** When the SQLITE_SYNC_DATAONLY flag is used, it means that the

//	** only way to prevent a call to xClose following a failed [sqlite3_vfs.xOpen]
//	** is for the [sqlite3_vfs.xOpen] to set the sqlite3_file.pMethods element

//	** The flags argument to xSync may be one of [SQLITE_SYNC_NORMAL] or
//	** [SQLITE_SYNC_FULL].  The first choice is the normal fsync().

//	** xLock() upgrades the database file lock.  In other words, xLock() moves the
//	** database file lock in the direction NONE toward EXCLUSIVE. The argument to
//	** xLock() is always on of SHARED, RESERVED, PENDING, or EXCLUSIVE, never

//	** to xUnlock() is a no-op.
//	** The xCheckReservedLock() method checks whether any database connection,
//	** either in this process or in some other process, is holding a RESERVED,
//	** PENDING, or EXCLUSIVE lock on the file.  It returns true
//	** if such a lock exists and false otherwise.
//	**
//	** The xFileControl() method is a generic interface that allows custom
//	** VFS implementations to directly control an open file using the
//	** [sqlite3_file_control()] interface.  The second "op" argument is an

//	** point to a structure that may contain arguments or space in which to
//	** write return values.  Potential uses for xFileControl() might be
//	** functions to enable blocking locks with timeouts, to change the
//	** locking strategy (for example to use dot-file locks), to inquire
//	** about the status of a lock, or to break stale locks.  The SQLite

/*
** CAPI3REF: Standard File Control Opcodes
** KEYWORDS: {file control opcodes} {file control opcode}
**
** These integer constants are opcodes for the xFileControl method
** of the [sqlite3_io_methods] object and for the [sqlite3_file_control()]
** interface.
**
** <ul>
** <li>[[SQLITE_FCNTL_LOCKSTATE]]
** The [SQLITE_FCNTL_LOCKSTATE] opcode is used for debugging.  This
** opcode causes the xFileControl method to write the current state of
** the lock (one of [SQLITE_LOCK_NONE], [SQLITE_LOCK_SHARED],
** [SQLITE_LOCK_RESERVED], [SQLITE_LOCK_PENDING], or [SQLITE_LOCK_EXCLUSIVE])
** into an integer that the pArg argument points to.
** This capability is only available if SQLite is compiled with [SQLITE_DEBUG].
**
** <li>[[SQLITE_FCNTL_SIZE_HINT]]
** The [SQLITE_FCNTL_SIZE_HINT] opcode is used by SQLite to give the VFS
** layer a hint of how large the database file will grow to be during the
** current transaction.  This hint is not guaranteed to be accurate but it
** is often close.  The underlying VFS might choose to preallocate database
** file space based on this hint in order to help writes to the database
** file run faster.
**
** <li>[[SQLITE_FCNTL_SIZE_LIMIT]]
** The [SQLITE_FCNTL_SIZE_LIMIT] opcode is used by in-memory VFS that
** implements [sqlite3_deserialize()] to set an upper bound on the size
** of the in-memory database.  The argument is a pointer to a [sqlite3_int64].
** If the integer pointed to is negative, then it is filled in with the
** current limit.  Otherwise the limit is set to the larger of the value
** of the integer pointed to and the current database size.  The integer
** pointed to is set to the new limit.
**
** <li>[[SQLITE_FCNTL_CHUNK_SIZE]]
** The [SQLITE_FCNTL_CHUNK_SIZE] opcode is used to request that the VFS
** extends and truncates the database file in chunks of a size specified
** by the user. The fourth argument to [sqlite3_file_control()] should
** point to an integer (type int) containing the new chunk-size to use
** for the nominated database. Allocating database file space in large
** chunks (say 1MB at a time), may reduce file-system fragmentation and
** improve performance on some systems.
**
** <li>[[SQLITE_FCNTL_FILE_POINTER]]
** The [SQLITE_FCNTL_FILE_POINTER] opcode is used to obtain a pointer
** to the [sqlite3_file] object associated with a particular database
** connection.  See also [SQLITE_FCNTL_JOURNAL_POINTER].
**
** <li>[[SQLITE_FCNTL_JOURNAL_POINTER]]
** The [SQLITE_FCNTL_JOURNAL_POINTER] opcode is used to obtain a pointer
** to the [sqlite3_file] object associated with the journal file (either
** the [rollback journal] or the [write-ahead log]) for a particular database
** connection.  See also [SQLITE_FCNTL_FILE_POINTER].
**
** <li>[[SQLITE_FCNTL_SYNC_OMITTED]]
** No longer in use.
**
** <li>[[SQLITE_FCNTL_SYNC]]
** The [SQLITE_FCNTL_SYNC] opcode is generated internally by SQLite and
** sent to the VFS immediately before the xSync method is invoked on a
** database file descriptor. Or, if the xSync method is not invoked
** because the user has configured SQLite with
** [PRAGMA synchronous | PRAGMA synchronous=OFF] it is invoked in place
** of the xSync method. In most cases, the pointer argument passed with
** this file-control is NULL. However, if the database file is being synced
** as part of a multi-database commit, the argument points to a nul-terminated
** string containing the transactions super-journal file name. VFSes that
** do not need this signal should silently ignore this opcode. Applications
** should not call [sqlite3_file_control()] with this opcode as doing so may
** disrupt the operation of the specialized VFSes that do require it.
**
** <li>[[SQLITE_FCNTL_COMMIT_PHASETWO]]
** The [SQLITE_FCNTL_COMMIT_PHASETWO] opcode is generated internally by SQLite
** and sent to the VFS after a transaction has been committed immediately
** but before the database is unlocked. VFSes that do not need this signal
** should silently ignore this opcode. Applications should not call
** [sqlite3_file_control()] with this opcode as doing so may disrupt the
** operation of the specialized VFSes that do require it.
**
** <li>[[SQLITE_FCNTL_WIN32_AV_RETRY]]
** ^The [SQLITE_FCNTL_WIN32_AV_RETRY] opcode is used to configure automatic
** retry counts and intervals for certain disk I/O operations for the
** windows [VFS] in order to provide robustness in the presence of
** anti-virus programs.  By default, the windows VFS will retry file read,
** file write, and file delete operations up to 10 times, with a delay
** of 25 milliseconds before the first retry and with the delay increasing
** by an additional 25 milliseconds with each subsequent retry.  This
** opcode allows these two values (10 retries and 25 milliseconds of delay)
** to be adjusted.  The values are changed for all database connections
** within the same process.  The argument is a pointer to an array of two
** integers where the first integer is the new retry count and the second
** integer is the delay.  If either integer is negative, then the setting
** is not changed but instead the prior value of that setting is written
** into the array entry, allowing the current retry settings to be
** interrogated.  The zDbName parameter is ignored.
**
** <li>[[SQLITE_FCNTL_PERSIST_WAL]]
** ^The [SQLITE_FCNTL_PERSIST_WAL] opcode is used to set or query the
** persistent [WAL | Write Ahead Log] setting.  By default, the auxiliary
** write ahead log ([WAL file]) and shared memory
** files used for transaction control
** are automatically deleted when the latest connection to the database
** closes.  Setting persistent WAL mode causes those files to persist after
** close.  Persisting the files is useful when other processes that do not
** have write permission on the directory containing the database file want
** to read the database file, as the WAL and shared memory files must exist
** in order for the database to be readable.  The fourth parameter to
** [sqlite3_file_control()] for this opcode should be a pointer to an integer.
** That integer is 0 to disable persistent WAL mode or 1 to enable persistent
** WAL mode.  If the integer is -1, then it is overwritten with the current
** WAL persistence setting.
**
** <li>[[SQLITE_FCNTL_POWERSAFE_OVERWRITE]]
** ^The [SQLITE_FCNTL_POWERSAFE_OVERWRITE] opcode is used to set or query the
** persistent "powersafe-overwrite" or "PSOW" setting.  The PSOW setting
** determines the [SQLITE_IOCAP_POWERSAFE_OVERWRITE] bit of the
** xDeviceCharacteristics methods. The fourth parameter to
** [sqlite3_file_control()] for this opcode should be a pointer to an integer.
** That integer is 0 to disable zero-damage mode or 1 to enable zero-damage
** mode.  If the integer is -1, then it is overwritten with the current
** zero-damage mode setting.
**
** <li>[[SQLITE_FCNTL_OVERWRITE]]
** ^The [SQLITE_FCNTL_OVERWRITE] opcode is invoked by SQLite after opening
** a write transaction to indicate that, unless it is rolled back for some
** reason, the entire database file will be overwritten by the current
** transaction. This is used by VACUUM operations.
**
** <li>[[SQLITE_FCNTL_VFSNAME]]
** ^The [SQLITE_FCNTL_VFSNAME] opcode can be used to obtain the names of
** all [VFSes] in the VFS stack.  The names are of all VFS shims and the
** final bottom-level VFS are written into memory obtained from
** [sqlite3_malloc()] and the result is stored in the char* variable
** that the fourth parameter of [sqlite3_file_control()] points to.
** The caller is responsible for freeing the memory when done.  As with
** all file-control actions, there is no guarantee that this will actually
** do anything.  Callers should initialize the char* variable to a NULL
** pointer in case this file-control is not implemented.  This file-control
** is intended for diagnostic use only.
**
** <li>[[SQLITE_FCNTL_VFS_POINTER]]
** ^The [SQLITE_FCNTL_VFS_POINTER] opcode finds a pointer to the top-level
** [VFSes] currently in use.  ^(The argument X in
** sqlite3_file_control(db,SQLITE_FCNTL_VFS_POINTER,X) must be
** of type "[sqlite3_vfs] **".  This opcodes will set *X
** to a pointer to the top-level VFS.)^
** ^When there are multiple VFS shims in the stack, this opcode finds the
** upper-most shim only.
**
** <li>[[SQLITE_FCNTL_PRAGMA]]
** ^Whenever a [PRAGMA] statement is parsed, an [SQLITE_FCNTL_PRAGMA]
** file control is sent to the open [sqlite3_file] object corresponding
** to the database file to which the pragma statement refers. ^The argument
** to the [SQLITE_FCNTL_PRAGMA] file control is an array of
** pointers to strings (char**) in which the second element of the array
** is the name of the pragma and the third element is the argument to the
** pragma or NULL if the pragma has no argument.  ^The handler for an
** [SQLITE_FCNTL_PRAGMA] file control can optionally make the first element
** of the char** argument point to a string obtained from [sqlite3_mprintf()]
** or the equivalent and that string will become the result of the pragma or
** the error message if the pragma fails. ^If the
** [SQLITE_FCNTL_PRAGMA] file control returns [SQLITE_NOTFOUND], then normal
** [PRAGMA] processing continues.  ^If the [SQLITE_FCNTL_PRAGMA]
** file control returns [SQLITE_OK], then the parser assumes that the
** VFS has handled the PRAGMA itself and the parser generates a no-op
** prepared statement if result string is NULL, or that returns a copy
** of the result string if the string is non-NULL.
** ^If the [SQLITE_FCNTL_PRAGMA] file control returns
** any result code other than [SQLITE_OK] or [SQLITE_NOTFOUND], that means
** that the VFS encountered an error while handling the [PRAGMA] and the
** compilation of the PRAGMA fails with an error.  ^The [SQLITE_FCNTL_PRAGMA]
** file control occurs at the beginning of pragma statement analysis and so
** it is able to override built-in [PRAGMA] statements.
**
** <li>[[SQLITE_FCNTL_BUSYHANDLER]]
** ^The [SQLITE_FCNTL_BUSYHANDLER]
** file-control may be invoked by SQLite on the database file handle
** shortly after it is opened in order to provide a custom VFS with access
** to the connection's busy-handler callback. The argument is of type (void**)
** - an array of two (void *) values. The first (void *) actually points
** to a function of type (int (*)(void *)). In order to invoke the connection's
** busy-handler, this function should be invoked with the second (void *) in
** the array as the only argument. If it returns non-zero, then the operation
** should be retried. If it returns zero, the custom VFS should abandon the
** current operation.
**
** <li>[[SQLITE_FCNTL_TEMPFILENAME]]
** ^Applications can invoke the [SQLITE_FCNTL_TEMPFILENAME] file-control
** to have SQLite generate a
** temporary filename using the same algorithm that is followed to generate
** temporary filenames for TEMP tables and other internal uses.  The
** argument should be a char** which will be filled with the filename
** written into memory obtained from [sqlite3_malloc()].  The caller should
** invoke [sqlite3_free()] on the result to avoid a memory leak.
**
** <li>[[SQLITE_FCNTL_MMAP_SIZE]]
** The [SQLITE_FCNTL_MMAP_SIZE] file control is used to query or set the
** maximum number of bytes that will be used for memory-mapped I/O.
** The argument is a pointer to a value of type sqlite3_int64 that
** is an advisory maximum number of bytes in the file to memory map.  The
** pointer is overwritten with the old value.  The limit is not changed if
** the value originally pointed to is negative, and so the current limit
** can be queried by passing in a pointer to a negative number.  This
** file-control is used internally to implement [PRAGMA mmap_size].
**
** <li>[[SQLITE_FCNTL_TRACE]]
** The [SQLITE_FCNTL_TRACE] file control provides advisory information
** to the VFS about what the higher layers of the SQLite stack are doing.
** This file control is used by some VFS activity tracing [shims].
** The argument is a zero-terminated string.  Higher layers in the
** SQLite stack may generate instances of this file control if
** the [SQLITE_USE_FCNTL_TRACE] compile-time option is enabled.
**
** <li>[[SQLITE_FCNTL_HAS_MOVED]]
** The [SQLITE_FCNTL_HAS_MOVED] file control interprets its argument as a
** pointer to an integer and it writes a boolean into that integer depending
** on whether or not the file has been renamed, moved, or deleted since it
** was first opened.
**
** <li>[[SQLITE_FCNTL_WIN32_GET_HANDLE]]
** The [SQLITE_FCNTL_WIN32_GET_HANDLE] opcode can be used to obtain the
** underlying native file handle associated with a file handle.  This file
** control interprets its argument as a pointer to a native file handle and
** writes the resulting value there.
**
** <li>[[SQLITE_FCNTL_WIN32_SET_HANDLE]]
** The [SQLITE_FCNTL_WIN32_SET_HANDLE] opcode is used for debugging.  This
** opcode causes the xFileControl method to swap the file handle with the one
** pointed to by the pArg argument.  This capability is used during testing
** and only needs to be supported when SQLITE_TEST is defined.
**
** <li>[[SQLITE_FCNTL_WAL_BLOCK]]
** The [SQLITE_FCNTL_WAL_BLOCK] is a signal to the VFS layer that it might
** be advantageous to block on the next WAL lock if the lock is not immediately
** available.  The WAL subsystem issues this signal during rare
** circumstances in order to fix a problem with priority inversion.
** Applications should <em>not</em> use this file-control.
**
** <li>[[SQLITE_FCNTL_ZIPVFS]]
** The [SQLITE_FCNTL_ZIPVFS] opcode is implemented by zipvfs only. All other
** VFS should return SQLITE_NOTFOUND for this opcode.
**
** <li>[[SQLITE_FCNTL_RBU]]
** The [SQLITE_FCNTL_RBU] opcode is implemented by the special VFS used by
** the RBU extension only.  All other VFS should return SQLITE_NOTFOUND for
** this opcode.
**
** <li>[[SQLITE_FCNTL_BEGIN_ATOMIC_WRITE]]
** If the [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] opcode returns SQLITE_OK, then
** the file descriptor is placed in "batch write mode", which
** means all subsequent write operations will be deferred and done
** atomically at the next [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE].  Systems
** that do not support batch atomic writes will return SQLITE_NOTFOUND.
** ^Following a successful SQLITE_FCNTL_BEGIN_ATOMIC_WRITE and prior to
** the closing [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE] or
** [SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE], SQLite will make
** no VFS interface calls on the same [sqlite3_file] file descriptor
** except for calls to the xWrite method and the xFileControl method
** with [SQLITE_FCNTL_SIZE_HINT].
**
** <li>[[SQLITE_FCNTL_COMMIT_ATOMIC_WRITE]]
** The [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE] opcode causes all write
** operations since the previous successful call to
** [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] to be performed atomically.
** This file control returns [SQLITE_OK] if and only if the writes were
** all performed successfully and have been committed to persistent storage.
** ^Regardless of whether or not it is successful, this file control takes
** the file descriptor out of batch write mode so that all subsequent
** write operations are independent.
** ^SQLite will never invoke SQLITE_FCNTL_COMMIT_ATOMIC_WRITE without
** a prior successful call to [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE].
**
** <li>[[SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE]]
** The [SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE] opcode causes all write
** operations since the previous successful call to
** [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] to be rolled back.
** ^This file control takes the file descriptor out of batch write mode
** so that all subsequent write operations are independent.
** ^SQLite will never invoke SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE without
** a prior successful call to [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE].
**
** <li>[[SQLITE_FCNTL_LOCK_TIMEOUT]]
** The [SQLITE_FCNTL_LOCK_TIMEOUT] opcode is used to configure a VFS
** to block for up to M milliseconds before failing when attempting to
** obtain a file lock using the xLock or xShmLock methods of the VFS.
** The parameter is a pointer to a 32-bit signed integer that contains
** the value that M is to be set to. Before returning, the 32-bit signed
** integer is overwritten with the previous value of M.
**
** <li>[[SQLITE_FCNTL_DATA_VERSION]]
** The [SQLITE_FCNTL_DATA_VERSION] opcode is used to detect changes to
** a database file.  The argument is a pointer to a 32-bit unsigned integer.
** The "data version" for the pager is written into the pointer.  The
** "data version" changes whenever any change occurs to the corresponding
** database file, either through SQL statements on the same database
** connection or through transactions committed by separate database
** connections possibly in other processes. The [sqlite3_total_changes()]
** interface can be used to find if any database on the connection has changed,
** but that interface responds to changes on TEMP as well as MAIN and does
** not provide a mechanism to detect changes to MAIN only.  Also, the
** [sqlite3_total_changes()] interface responds to internal changes only and
** omits changes made by other database connections.  The
** [PRAGMA data_version] command provides a mechanism to detect changes to
** a single attached database that occur due to other database connections,
** but omits changes implemented by the database connection on which it is
** called.  This file control is the only mechanism to detect changes that
** happen either internally or externally and that are associated with
** a particular attached database.
**
** <li>[[SQLITE_FCNTL_CKPT_START]]
** The [SQLITE_FCNTL_CKPT_START] opcode is invoked from within a checkpoint
** in wal mode before the client starts to copy pages from the wal
** file to the database file.
**
** <li>[[SQLITE_FCNTL_CKPT_DONE]]
** The [SQLITE_FCNTL_CKPT_DONE] opcode is invoked from within a checkpoint
** in wal mode after the client has finished copying pages from the wal
** file to the database file, but before the *-shm file is updated to
** record the fact that the pages have been checkpointed.
**
** <li>[[SQLITE_FCNTL_EXTERNAL_READER]]
** The EXPERIMENTAL [SQLITE_FCNTL_EXTERNAL_READER] opcode is used to detect
** whether or not there is a database client in another process with a wal-mode
** transaction open on the database or not. It is only available on unix.The
** (void*) argument passed with this file-control should be a pointer to a
** value of type (int). The integer value is set to 1 if the database is a wal
** mode database and there exists at least one client in another process that
** currently has an SQL transaction open on the database. It is set to 0 if
** the database is not a wal-mode db, or if there is no such connection in any
** other process. This opcode cannot be used to detect transactions opened
** by clients within the current process, only within other processes.
**
** <li>[[SQLITE_FCNTL_CKSM_FILE]]
** The [SQLITE_FCNTL_CKSM_FILE] opcode is for use internally by the
** [checksum VFS shim] only.
**
** <li>[[SQLITE_FCNTL_RESET_CACHE]]
** If there is currently no transaction open on the database, and the
** database is not a temp db, then the [SQLITE_FCNTL_RESET_CACHE] file-control
** purges the contents of the in-memory page cache. If there is an open
** transaction, or if the db is a temp-db, this opcode is a no-op, not an error.

//	/*
//	** CAPI3REF: OS Interface Object
//	**
//	** An instance of the sqlite3_vfs object defines the interface between
//	** the SQLite core and the underlying operating system.  The "vfs"
//	** in the name of the object stands for "virtual file system".  See
//	** the [VFS | VFS documentation] for further information.
//	**
//	** The VFS interface is sometimes extended by adding new methods onto
//	** the end.  Each time such an extension occurs, the iVersion field
//	** is incremented.  The iVersion value started out as 1 in
//	** SQLite [version 3.5.0] on [dateof:3.5.0], then increased to 2
//	** with SQLite [version 3.7.0] on [dateof:3.7.0], and then increased
//	** to 3 with SQLite [version 3.7.6] on [dateof:3.7.6].  Additional fields
//	** may be appended to the sqlite3_vfs object and the iVersion value
//	** may increase again in future versions of SQLite.
//	** Note that due to an oversight, the structure
//	** of the sqlite3_vfs object changed in the transition from
//	** SQLite [version 3.5.9] to [version 3.6.0] on [dateof:3.6.0]
//	** and yet the iVersion field was not increased.
//	**
//	** The szOsFile field is the size of the subclassed [sqlite3_file]
//	** structure used by this VFS.  mxPathname is the maximum length of
//	** a pathname in this VFS.
//	**
//	** Registered sqlite3_vfs objects are kept on a linked list formed by
//	** the pNext pointer.  The [sqlite3_vfs_register()]
//	** and [sqlite3_vfs_unregister()] interfaces manage this list
//	** in a thread-safe way.  The [sqlite3_vfs_find()] interface
//	** searches the list.  Neither the application code nor the VFS
//	** implementation should use the pNext pointer.
//	**
//	** The pNext field is the only field in the sqlite3_vfs
//	** structure that SQLite will ever modify.  SQLite will only access
//	** or modify this field while holding a particular static mutex.
//	** The application should never modify anything within the sqlite3_vfs
//	** object once the object has been registered.
//	**
//	** The zName field holds the name of the VFS module.  The name must
//	** be unique across all VFS modules.
//	**
//	** [[sqlite3_vfs.xOpen]]
//	** ^SQLite guarantees that the zFilename parameter to xOpen
//	** is either a NULL pointer or string obtained
//	** from xFullPathname() with an optional suffix added.
//	** ^If a suffix is added to the zFilename parameter, it will
//	** consist of a single "-" character followed by no more than
//	** 11 alphanumeric and/or "-" characters.
//	** ^SQLite further guarantees that
//	** the string will be valid and unchanged until xClose() is
//	** called. Because of the previous sentence,
//	** the [sqlite3_file] can safely store a pointer to the
//	** filename if it needs to remember the filename for some reason.
//	** If the zFilename parameter to xOpen is a NULL pointer then xOpen
//	** must invent its own temporary name for the file.  ^Whenever the
//	** xFilename parameter is NULL it will also be the case that the
//	** flags parameter will include [SQLITE_OPEN_DELETEONCLOSE].
//	**
//	** The flags argument to xOpen() includes all bits set in
//	** the flags argument to [sqlite3_open_v2()].  Or if [sqlite3_open()]
//	** or [sqlite3_open16()] is used, then flags includes at least
//	** [SQLITE_OPEN_READWRITE] | [SQLITE_OPEN_CREATE].
//	** If xOpen() opens a file read-only then it sets *pOutFlags to
//	** include [SQLITE_OPEN_READONLY].  Other bits in *pOutFlags may be set.
//	**
//	** ^(SQLite will also add one of the following flags to the xOpen()
//	** call, depending on the object being opened:
//	**
//	** <ul>
//	** <li>  [SQLITE_OPEN_MAIN_DB]
//	** <li>  [SQLITE_OPEN_MAIN_JOURNAL]
//	** <li>  [SQLITE_OPEN_TEMP_DB]
//	** <li>  [SQLITE_OPEN_TEMP_JOURNAL]
//	** <li>  [SQLITE_OPEN_TRANSIENT_DB]
//	** <li>  [SQLITE_OPEN_SUBJOURNAL]
//	** <li>  [SQLITE_OPEN_SUPER_JOURNAL]
//	** <li>  [SQLITE_OPEN_WAL]
//	** </ul>)^
//	**
//	** The file I/O implementation can use the object type flags to
//	** change the way it deals with files.  For example, an application
//	** that does not care about crash recovery or rollback might make
//	** the open of a journal file a no-op.  Writes to this journal would
//	** also be no-ops, and any attempt to read the journal would return
//	** SQLITE_IOERR.  Or the implementation might recognize that a database
//	** file will be doing page-aligned sector reads and writes in a random
//	** order and set up its I/O subsystem accordingly.
//	**
//	** SQLite might also add one of the following flags to the xOpen method:
//	**
//	** <ul>
//	** <li> [SQLITE_OPEN_DELETEONCLOSE]
//	** <li> [SQLITE_OPEN_EXCLUSIVE]
//	** </ul>
//	**
//	** The [SQLITE_OPEN_DELETEONCLOSE] flag means the file should be
//	** deleted when it is closed.  ^The [SQLITE_OPEN_DELETEONCLOSE]
//	** will be set for TEMP databases and their journals, transient
//	** databases, and subjournals.
//	**
//	** ^The [SQLITE_OPEN_EXCLUSIVE] flag is always used in conjunction
//	** with the [SQLITE_OPEN_CREATE] flag, which are both directly
//	** analogous to the O_EXCL and O_CREAT flags of the POSIX open()
//	** API.  The SQLITE_OPEN_EXCLUSIVE flag, when paired with the
//	** SQLITE_OPEN_CREATE, is used to indicate that file should always
//	** be created, and that it is an error if it already exists.
//	** It is <i>not</i> used to indicate the file should be opened
//	** for exclusive access.
//	**
//	** ^At least szOsFile bytes of memory are allocated by SQLite
//	** to hold the [sqlite3_file] structure passed as the third
//	** argument to xOpen.  The xOpen method does not have to
//	** allocate the structure; it should just fill it in.  Note that
//	** the xOpen method must set the sqlite3_file.pMethods to either
//	** a valid [sqlite3_io_methods] object or to NULL.  xOpen must do
//	** this even if the open fails.  SQLite expects that the sqlite3_file.pMethods
//	** element will be valid after xOpen returns regardless of the success
//	** or failure of the xOpen call.
//	**
//	** [[sqlite3_vfs.xAccess]]
//	** ^The flags argument to xAccess() may be [SQLITE_ACCESS_EXISTS]
//	** to test for the existence of a file, or [SQLITE_ACCESS_READWRITE] to
//	** test whether a file is readable and writable, or [SQLITE_ACCESS_READ]
//	** to test whether a file is at least readable.  The SQLITE_ACCESS_READ
//	** flag is never actually used and is not implemented in the built-in
//	** VFSes of SQLite.  The file is named by the second argument and can be a
//	** directory. The xAccess method returns [SQLITE_OK] on success or some
//	** non-zero error code if there is an I/O error or if the name of
//	** the file given in the second argument is illegal.  If SQLITE_OK
//	** is returned, then non-zero or zero is written into *pResOut to indicate
//	** whether or not the file is accessible.
//	**
//	** ^SQLite will always allocate at least mxPathname+1 bytes for the
//	** output buffer xFullPathname.  The exact size of the output buffer
//	** is also passed as a parameter to both  methods. If the output buffer
//	** is not large enough, [SQLITE_CANTOPEN] should be returned. Since this is
//	** handled as a fatal error by SQLite, vfs implementations should endeavor
//	** to prevent this by setting mxPathname to a sufficiently large value.
//	**
//	** The xRandomness(), xSleep(), xCurrentTime(), and xCurrentTimeInt64()
//	** interfaces are not strictly a part of the filesystem, but they are
//	** included in the VFS structure for completeness.
//	** The xRandomness() function attempts to return nBytes bytes
//	** of good-quality randomness into zOut.  The return value is
//	** the actual number of bytes of randomness obtained.
//	** The xSleep() method causes the calling thread to sleep for at
//	** least the number of microseconds given.  ^The xCurrentTime()
//	** method returns a Julian Day Number for the current date and time as
//	** a floating point value.
//	** ^The xCurrentTimeInt64() method returns, as an integer, the Julian
//	** Day Number multiplied by 86400000 (the number of milliseconds in
//	** a 24-hour day).
//	** ^SQLite will use the xCurrentTimeInt64() method to get the current
//	** date and time if that method is available (if iVersion is 2 or
//	** greater and the function pointer is not NULL) and will fall back
//	** to xCurrentTime() if xCurrentTimeInt64() is unavailable.
//	**
//	** ^The xSetSystemCall(), xGetSystemCall(), and xNestSystemCall() interfaces
//	** are not used by the SQLite core.  These optional interfaces are provided
//	** by some VFSes to facilitate testing of the VFS code. By overriding
//	** system calls with functions under its control, a test program can
//	** simulate faults and error conditions that would otherwise be difficult
//	** or impossible to induce.  The set of system calls that can be overridden
//	** varies from one VFS to another, and from one version of the same VFS to the
//	** next.  Applications that use these interfaces must be prepared for any
//	** or all of these interfaces to be NULL or for their behavior to change
//	** from one release to the next.  Applications must not attempt to access
//	** any of these methods if the iVersion of the VFS is less than 3.

//	** CAPI3REF: Memory Allocation Routines
//	**
//	** An instance of this object defines the interface between SQLite
//	** and low-level memory allocation routines.
//	**
//	** This object is used in only one place in the SQLite interface.
//	** A pointer to an instance of this object is the argument to
//	** [sqlite3_config()] when the configuration option is
//	** [SQLITE_CONFIG_MALLOC] or [SQLITE_CONFIG_GETMALLOC].
//	** By creating an instance of this object
//	** and passing it to [sqlite3_config]([SQLITE_CONFIG_MALLOC])
//	** during configuration, an application can specify an alternative
//	** memory allocation subsystem for SQLite to use for all of its
//	** dynamic memory needs.
//	**
//	** Note that SQLite comes with several [built-in memory allocators]
//	** that are perfectly adequate for the overwhelming majority of applications
//	** and that this object is only useful to a tiny minority of applications
//	** with specialized memory allocation requirements.  This object is
//	** also used during testing of SQLite in order to specify an alternative
//	** memory allocator that simulates memory out-of-memory conditions in
//	** order to verify that SQLite recovers gracefully from such
//	** conditions.
//	**
//	** The xMalloc, xRealloc, and xFree methods must work like the
//	** malloc(), realloc() and free() functions from the standard C library.
//	** ^SQLite guarantees that the second argument to
//	** xRealloc is always a value returned by a prior call to xRoundup.
//	**
//	** xSize should return the allocated size of a memory allocation
//	** previously obtained from xMalloc or xRealloc.  The allocated size
//	** is always at least as big as the requested size but may be larger.
//	**
//	** The xRoundup method returns what would be the allocated size of
//	** a memory allocation given a particular requested size.  Most memory
//	** allocators round up memory allocations at least to the next multiple
//	** of 8.  Some allocators round up to a larger multiple or to a power of 2.
//	** Every memory allocation request coming in through [sqlite3_malloc()]
//	** or [sqlite3_realloc()] first calls xRoundup.  If xRoundup returns 0,
//	** that causes the corresponding memory allocation to fail.
//	**
//	** The xInit method initializes the memory allocator.  For example,
//	** it might allocate any required mutexes or initialize internal data
//	** structures.  The xShutdown method is invoked (indirectly) by
//	** [sqlite3_shutdown()] and should deallocate any resources acquired
//	** by xInit.  The pAppData pointer is used as the only parameter to
//	** xInit and xShutdown.
//	**
//	** SQLite holds the [SQLITE_MUTEX_STATIC_MAIN] mutex when it invokes
//	** the xInit method, so the xInit method need not be threadsafe.  The
//	** xShutdown method is only called from [sqlite3_shutdown()] so it does
//	** not need to be threadsafe either.  For all other methods, SQLite
//	** holds the [SQLITE_MUTEX_STATIC_MEM] mutex as long as the
//	** [SQLITE_CONFIG_MEMSTATUS] configuration option is turned on (which
//	** it is by default) and so the methods are automatically serialized.
//	** However, if [SQLITE_CONFIG_MEMSTATUS] is disabled, then the other
//	** methods must be threadsafe or else make their own arrangements for
//	** serialization.

** CAPI3REF: Virtual Table Indexing Information
** KEYWORDS: sqlite3_index_info
**
** The sqlite3_index_info structure and its substructures is used as part
** of the [virtual table] interface to
** pass information into and receive the reply from the [xBestIndex]
** method of a [virtual table module].  The fields under **Inputs** are the
** inputs to xBestIndex and are read-only.  xBestIndex inserts its
** results into the **Outputs** fields.
**
** ^(The aConstraint[] array records WHERE clause constraints of the form:
**
** <blockquote>column OP expr</blockquote>
**
** where OP is =, &lt;, &lt;=, &gt;, or &gt;=.)^  ^(The particular operator is
** stored in aConstraint[].op using one of the
** [SQLITE_INDEX_CONSTRAINT_EQ | SQLITE_INDEX_CONSTRAINT_ values].)^
** ^(The index of the column is stored in
** aConstraint[].iColumn.)^  ^(aConstraint[].usable is TRUE if the
** expr on the right-hand side can be evaluated (and thus the constraint
** is usable) and false if it cannot.)^
**
** ^The optimizer automatically inverts terms of the form "expr OP column"
** and makes other simplifications to the WHERE clause in an attempt to
** get as many WHERE clause terms into the form shown above as possible.
** ^The aConstraint[] array only reports WHERE clause terms that are
** relevant to the particular virtual table being queried.
**
** ^Information about the ORDER BY clause is stored in aOrderBy[].
** ^Each term of aOrderBy records a column of the ORDER BY clause.
**
** The colUsed field indicates which columns of the virtual table may be
** required by the current scan. Virtual table columns are numbered from
** zero in the order in which they appear within the CREATE TABLE statement
** passed to sqlite3_declare_vtab(). For the first 63 columns (columns 0-62),
** the corresponding bit is set within the colUsed mask if the column may be
** required by SQLite. If the table has at least 64 columns and any column
** to the right of the first 63 is required, then bit 63 of colUsed is also
** set. In other words, column iCol may be required if the expression
** (colUsed & ((sqlite3_uint64)1 << (iCol>=63 ? 63 : iCol))) evaluates to
** non-zero.
**
** The [xBestIndex] method must fill aConstraintUsage[] with information
** about what parameters to pass to xFilter.  ^If argvIndex>0 then
** the right-hand side of the corresponding aConstraint[] is evaluated
** and becomes the argvIndex-th entry in argv.  ^(If aConstraintUsage[].omit
** is true, then the constraint is assumed to be fully handled by the
** virtual table and might not be checked again by the byte code.)^ ^(The
** aConstraintUsage[].omit flag is an optimization hint. When the omit flag
** is left in its default setting of false, the constraint will always be
** checked separately in byte code.  If the omit flag is change to true, then
** the constraint may or may not be checked in byte code.  In other words,
** when the omit flag is true there is no guarantee that the constraint will
** not be checked again using byte code.)^
**
** ^The idxNum and idxStr values are recorded and passed into the
** [xFilter] method.
** ^[sqlite3_free()] is used to free idxStr if and only if
** needToFreeIdxStr is true.
**
** ^The orderByConsumed means that output from [xFilter]/[xNext] will occur in
** the correct order to satisfy the ORDER BY clause so that no separate
** sorting step is required.
**
** ^The estimatedCost value is an estimate of the cost of a particular
** strategy. A cost of N indicates that the cost of the strategy is similar
** to a linear scan of an SQLite table with N rows. A cost of log(N)
** indicates that the expense of the operation is similar to that of a
** binary search on a unique indexed field of an SQLite table with N rows.
**
** ^The estimatedRows value is an estimate of the number of rows that
** will be returned by the strategy.
**
** The xBestIndex method may optionally populate the idxFlags field with a
** mask of SQLITE_INDEX_SCAN_* flags. Currently there is only one such flag -
** SQLITE_INDEX_SCAN_UNIQUE. If the xBestIndex method sets this flag, SQLite
** assumes that the strategy may visit at most one row.
**
** Additionally, if xBestIndex sets the SQLITE_INDEX_SCAN_UNIQUE flag, then
** SQLite also assumes that if a call to the xUpdate() method is made as
** part of the same statement to delete or update a virtual table row and the
** implementation returns SQLITE_CONSTRAINT, then there is no need to rollback
** any database changes. In other words, if the xUpdate() returns
** SQLITE_CONSTRAINT, the database contents must be exactly as they were
** before xUpdate was called. By contrast, if SQLITE_INDEX_SCAN_UNIQUE is not
** set and xUpdate returns SQLITE_CONSTRAINT, any database changes made by
** the xUpdate method are automatically rolled back by SQLite.
**
** IMPORTANT: The estimatedRows field was added to the sqlite3_index_info
** structure for SQLite [version 3.8.2] ([dateof:3.8.2]).
** If a virtual table extension is
** used with an SQLite version earlier than 3.8.2, the results of attempting
** to read or write the estimatedRows field are undefined (but are likely
** to include crashing the application). The estimatedRows field should
** therefore only be used if [sqlite3_libversion_number()] returns a
** value greater than or equal to 3008002. Similarly, the idxFlags field
** was added for [version 3.9.0] ([dateof:3.9.0]).
** It may therefore only be used if
** sqlite3_libversion_number() returns a value greater than or equal to
** 3009000.

//	** ^The xShutdown() method may be NULL.
//	**
//	** ^SQLite automatically serializes calls to the xInit method,

//	** not need to be threadsafe either.  All other methods must be threadsafe
//	** in multithreaded applications.
//	**
//	** ^SQLite will never invoke xInit() more than once without an intervening
//	** call to xShutdown().
//	**
//	** [[the xCreate() page cache methods]]
//	** ^SQLite invokes the xCreate() method to construct a new cache instance.
//	** SQLite will typically create one cache instance for each open database file,
//	** though this is not guaranteed. ^The
//	** first parameter, szPage, is the size in bytes of the pages that must
//	** be allocated by the cache.  ^szPage will always a power of two.  ^The

//	** extra szExtra bytes on each page to store metadata about the underlying
//	** database page on disk.  The value passed into szExtra depends
//	** on the SQLite version, the target platform, and how SQLite was compiled.
//	** ^The third argument to xCreate(), bPurgeable, is true if the cache being
//	** created will be used to cache database pages of a file stored on disk, or
//	** false if it is used for an in-memory database. The cache implementation
//	** does not have to do anything special based with the value of bPurgeable;
//	** it is purely advisory.  ^On a cache where bPurgeable is false, SQLite will
//	** never invoke xUnpin() except to deliberately delete a page.
//	** ^In other words, calls to xUnpin() on a cache with bPurgeable set to
//	** false will always have the "discard" flag set to true.
//	** ^Hence, a cache created with bPurgeable false will
//	** never contain any unpinned pages.
//	**
//	** [[the xCachesize() page cache method]]
//	** ^(The xCachesize() method may be called at any time by SQLite to set the

//	** parameter, the implementation is not required to do anything with this
//	** value; it is advisory only.
//	**
//	** [[the xPagecount() page cache methods]]
//	** The xPagecount() method must return the number of pages currently
//	** stored in the cache, both pinned and unpinned.
//	**
//	** [[the xFetch() page cache methods]]
//	** The xFetch() method locates a page in the cache and returns a pointer to
//	** an sqlite3_pcache_page object associated with that page, or a NULL pointer.
//	** The pBuf element of the returned sqlite3_pcache_page object will be a
//	** pointer to a buffer of szPage bytes used to store the content of a
//	** single database page.  The pExtra element of sqlite3_pcache_page will be
//	** a pointer to the szExtra bytes of extra storage that SQLite has requested
//	** for each entry in the page cache.
//	**
//	** The page to be fetched is determined by the key. ^The minimum key value
//	** is 1.  After it has been retrieved using xFetch, the page is considered
//	** to be "pinned".
//	**
//	** If the requested page is already in the page cache, then the page cache
//	** implementation must return a pointer to the page buffer with its content
//	** intact.  If the requested page is not already in the cache, then the
//	** cache implementation should use the value of the createFlag
//	** parameter to help it determined what action to take:
//	**
//	** <table border=1 width=85% align=center>
//	** <tr><th> createFlag <th> Behavior when page is not already in cache
//	** <tr><td> 0 <td> Do not allocate a new page.  Return NULL.
//	** <tr><td> 1 <td> Allocate a new page if it easy and convenient to do so.
//	**                 Otherwise return NULL.
//	** <tr><td> 2 <td> Make every effort to allocate a new page.  Only return
//	**                 NULL if allocating a new page is effectively impossible.
//	** </table>
//	**
//	** ^(SQLite will normally invoke xFetch() with a createFlag of 0 or 1.  SQLite
//	** will only use a createFlag of 2 after a prior call with a createFlag of 1
//	** failed.)^  In between the xFetch() calls, SQLite may
//	** attempt to unpin one or more cache pages by spilling the content of
//	** pinned pages to disk and synching the operating system disk cache.
//	**
//	** [[the xUnpin() page cache method]]
//	** ^xUnpin() is called by SQLite with a pointer to a currently pinned page
//	** as its second argument.  If the third parameter, discard, is non-zero,
//	** then the page must be evicted from the cache.
//	** ^If the discard parameter is
//	** zero, then the page may be discarded or retained at the discretion of
//	** page cache implementation. ^The page cache implementation
//	** may choose to evict unpinned pages at any time.
//	**
//	** The cache must not perform any reference counting. A single
//	** call to xUnpin() unpins the page regardless of the number of prior calls
//	** to xFetch().
//	**
//	** [[the xRekey() page cache methods]]
//	** The xRekey() method is used to change the key value associated with the
//	** page passed as the second argument. If the cache
//	** previously contains an entry associated with newKey, it must be
//	** discarded. ^Any prior cache entry associated with newKey is guaranteed not
//	** to be pinned.
//	**
//	** When SQLite calls the xTruncate() method, the cache must discard all
//	** existing cache entries with page numbers (keys) greater than or equal
//	** to the value of the iLimit parameter passed to xTruncate(). If any
//	** of these pages are pinned, they are implicitly unpinned, meaning that
//	** they can be safely discarded.
//	**
//	** [[the xDestroy() page cache method]]

**   in duplicate primary key values.
**
**   The conflicting row in this case is the database row with the matching
**   primary key.
**
** <dt>SQLITE_CHANGESET_FOREIGN_KEY<dd>

//	/*
//	** CAPI3REF: Rebasing changesets
//	** EXPERIMENTAL
//	**
//	** Suppose there is a site hosting a database in state S0. And that
//	** modifications are made that move that database to state S1 and a
//	** changeset recorded (the "local" changeset). Then, a changeset based
//	** on S0 is received from another site (the "remote" changeset) and
//	** applied to the database. The database is then in state
//	** (S1+"remote"), where the exact state depends on any conflict
//	** resolution decisions (OMIT or REPLACE) made while applying "remote".
//	** Rebasing a changeset is to update it to take those conflict
//	** resolution decisions into account, so that the same conflicts
//	** do not have to be resolved elsewhere in the network.
//	**
//	** For example, if both the local and remote changesets contain an
//	** INSERT of the same key on "CREATE TABLE t1(a PRIMARY KEY, b)":
//	**
//	**   local:  INSERT INTO t1 VALUES(1, 'v1');
//	**   remote: INSERT INTO t1 VALUES(1, 'v2');
//	**
//	** and the conflict resolution is REPLACE, then the INSERT change is
//	** removed from the local changeset (it was overridden). Or, if the
//	** conflict resolution was "OMIT", then the local changeset is modified
//	** to instead contain:
//	**
//	**           UPDATE t1 SET b = 'v2' WHERE a=1;
//	**
//	** Changes within the local changeset are rebased as follows:
//	**
//	** <dl>
//	** <dt>Local INSERT<dd>
//	**   This may only conflict with a remote INSERT. If the conflict
//	**   resolution was OMIT, then add an UPDATE change to the rebased
//	**   changeset. Or, if the conflict resolution was REPLACE, add
//	**   nothing to the rebased changeset.
//	**
//	** <dt>Local DELETE<dd>
//	**   This may conflict with a remote UPDATE or DELETE. In both cases the
//	**   only possible resolution is OMIT. If the remote operation was a
//	**   DELETE, then add no change to the rebased changeset. If the remote
//	**   operation was an UPDATE, then the old.* fields of change are updated
//	**   to reflect the new.* values in the UPDATE.
//	**
//	** <dt>Local UPDATE<dd>
//	**   This may conflict with a remote UPDATE or DELETE. If it conflicts
//	**   with a DELETE, and the conflict resolution was OMIT, then the update
//	**   is changed into an INSERT. Any undefined values in the new.* record
//	**   from the update change are filled in using the old.* values from
//	**   the conflicting DELETE. Or, if the conflict resolution was REPLACE,
//	**   the UPDATE change is simply omitted from the rebased changeset.
//	**
//	**   If conflict is with a remote UPDATE and the resolution is OMIT, then
//	**   the old.* values are rebased using the new.* values in the remote
//	**   change. Or, if the resolution is REPLACE, then the change is copied
//	**   into the rebased changeset with updates to columns also updated by
//	**   the conflicting remote UPDATE removed. If this means no columns would
//	**   be updated, the change is omitted.
//	** </dl>
//	**
//	** A local change may be rebased against multiple remote changes
//	** simultaneously. If a single key is modified by multiple remote
//	** changesets, they are combined as follows before the local changeset
//	** is rebased:
//	**
//	** <ul>
//	**    <li> If there has been one or more REPLACE resolutions on a
//	**         key, it is rebased according to a REPLACE.
//	**
//	**    <li> If there have been no REPLACE resolutions on a key, then
//	**         the local changeset is rebased according to the most recent
//	**         of the OMIT resolutions.
//	** </ul>
//	**
//	** Note that conflict resolutions from multiple remote changesets are
//	** combined on a per-field basis, not per-row. This means that in the
//	** case of multiple remote UPDATE operations, some fields of a single
//	** local change may be rebased for REPLACE while others are rebased for
//	** OMIT.
//	**
//	** In order to rebase a local changeset, the remote changeset must first
//	** be applied to the local database using sqlite3changeset_apply_v2() and
//	** the buffer of rebase information captured. Then:
//	**
//	** <ol>
//	**   <li> An sqlite3_rebaser object is created by calling
//	**        sqlite3rebaser_create().
//	**   <li> The new object is configured with the rebase buffer obtained from
//	**        sqlite3changeset_apply_v2() by calling sqlite3rebaser_configure().
//	**        If the local changeset is to be rebased against multiple remote
//	**        changesets, then sqlite3rebaser_configure() should be called
//	**        multiple times, in the same order that the multiple
//	**        sqlite3changeset_apply_v2() calls were made.
//	**   <li> Each local changeset is rebased by calling sqlite3rebaser_rebase().

** xColumnSize(pFts, iCol, pnToken):
**   If parameter iCol is less than zero, set output variable *pnToken
**   to the total number of tokens in the current row. Or, if iCol is
**   non-negative but less than the number of columns in the table, set
**   *pnToken to the number of tokens in column iCol of the current row.
**
**   If parameter iCol is greater than or equal to the number of columns
**   in the table, SQLITE_RANGE is returned. Or, if an error occurs (e.g.
**   an OOM condition or IO error), an appropriate SQLite error code is
**   returned.
**
**   This function may be quite inefficient if used with an FTS5 table
**   created with the "columnsize=0" option.
**
** xColumnText:
**   If parameter iCol is less than zero, or greater than or equal to the
**   number of columns in the table, SQLITE_RANGE is returned.
**
**   Otherwise, this function attempts to retrieve the text of column iCol of
**   the current document. If successful, (*pz) is set to point to a buffer
**   containing the text in utf-8 encoding, (*pn) is set to the size in bytes
**   (not characters) of the buffer and SQLITE_OK is returned. Otherwise,
**   if an error occurs, an SQLite error code is returned and the final values
**   of (*pz) and (*pn) are undefined.
**
** xPhraseCount:
**   Returns the number of phrases in the current query expression.
**
** xPhraseSize:
**   If parameter iCol is less than zero, or greater than or equal to the
**   number of phrases in the current query, as returned by xPhraseCount,
**   0 is returned. Otherwise, this function returns the number of tokens in
**   phrase iPhrase of the query. Phrases are numbered starting from zero.
**
** xInstCount:
**   Set *pnInst to the total number of occurrences of all phrases within
**   the query within the current row. Return SQLITE_OK if successful, or
**   an error code (i.e. SQLITE_NOMEM) if an error occurs.
**
**   This API can be quite slow if used with an FTS5 table created with the
**   "detail=none" or "detail=column" option. If the FTS5 table is created
**   with either "detail=none" or "detail=column" and "content=" option
**   (i.e. if it is a contentless table), then this API always returns 0.
**
** xInst:
**   Query for the details of phrase match iIdx within the current row.
**   Phrase matches are numbered starting from zero, so the iIdx argument
**   should be greater than or equal to zero and smaller than the value
**   output by xInstCount(). If iIdx is less than zero or greater than
**   or equal to the value returned by xInstCount(), SQLITE_RANGE is returned.
**
**   Otherwise, output parameter *piPhrase is set to the phrase number, *piCol
**   to the column in which it occurs and *piOff the token offset of the
**   first token of the phrase. SQLITE_OK is returned if successful, or an
**   error code (i.e. SQLITE_NOMEM) if an error occurs.
**
**   This API can be quite slow if used with an FTS5 table created with the
**   "detail=none" or "detail=column" option.
**
** xRowid:
**   Returns the rowid of the current row.
**
** xTokenize:
**   Tokenize text using the tokenizer belonging to the FTS5 table.
**
** xQueryPhrase(pFts5, iPhrase, pUserData, xCallback):
**   This API function is used to query the FTS table for phrase iPhrase
**   of the current query. Specifically, a query equivalent to:
**
**       ... FROM ftstable WHERE ftstable MATCH $p ORDER BY rowid
**
**   with $p set to a phrase equivalent to the phrase iPhrase of the
**   current query is executed. Any column filter that applies to
**   phrase iPhrase of the current query is included in $p. For each
**   row visited, the callback function passed as the fourth argument
**   is invoked. The context and API objects passed to the callback
**   function may be used to access the properties of each matched row.
**   Invoking Api.xUserData() returns a copy of the pointer passed as
**   the third argument to pUserData.
**
**   If parameter iPhrase is less than zero, or greater than or equal to
**   the number of phrases in the query, as returned by xPhraseCount(),
**   this function returns SQLITE_RANGE.
**
**   If the callback function returns any value other than SQLITE_OK, the
**   query is abandoned and the xQueryPhrase function returns immediately.
**   If the returned value is SQLITE_DONE, xQueryPhrase returns SQLITE_OK.
**   Otherwise, the error code is propagated upwards.
**
**   If the query runs to completion without incident, SQLITE_OK is returned.
**   Or, if some error occurs before the query completes or is aborted by
**   the callback, an SQLite error code is returned.
**
**
** xSetAuxdata(pFts5, pAux, xDelete)
**
**   Save the pointer passed as the second argument as the extension function's
**   "auxiliary data". The pointer may then be retrieved by the current or any
**   future invocation of the same fts5 extension function made as part of
**   the same MATCH query using the xGetAuxdata() API.
**
**   Each extension function is allocated a single auxiliary data slot for
**   each FTS query (MATCH expression). If the extension function is invoked
**   more than once for a single FTS query, then all invocations share a
**   single auxiliary data context.
**
**   If there is already an auxiliary data pointer when this function is
**   invoked, then it is replaced by the new pointer. If an xDelete callback
**   was specified along with the original pointer, it is invoked at this
**   point.
**
**   The xDelete callback, if one is specified, is also invoked on the
**   auxiliary data pointer after the FTS5 query has finished.
**
**   If an error (e.g. an OOM condition) occurs within this function,
**   the auxiliary data is set to NULL and an error code returned. If the
**   xDelete parameter was not NULL, it is invoked on the auxiliary data
**   pointer before returning.
**
**
** xGetAuxdata(pFts5, bClear)
**
**   Returns the current auxiliary data pointer for the fts5 extension
**   function. See the xSetAuxdata() method for details.
**
**   If the bClear argument is non-zero, then the auxiliary data is cleared
**   (set to NULL) before this function returns. In this case the xDelete,
**   if any, is not invoked.
**
**
** xRowCount(pFts5, pnRow)
**
**   This function is used to retrieve the total number of rows in the table.
**   In other words, the same value that would be returned by:
**
**        SELECT count(*) FROM ftstable;
**
** xPhraseFirst()
**   This function is used, along with type Fts5PhraseIter and the xPhraseNext
**   method, to iterate through all instances of a single query phrase within
**   the current row. This is the same information as is accessible via the
**   xInstCount/xInst APIs. While the xInstCount/xInst APIs are more convenient
**   to use, this API may be faster under some circumstances. To iterate
**   through instances of phrase iPhrase, use the following code:
**
**       Fts5PhraseIter iter;
**       int iCol, iOff;
**       for(pApi->xPhraseFirst(pFts, iPhrase, &iter, &iCol, &iOff);
**           iCol>=0;
**           pApi->xPhraseNext(pFts, &iter, &iCol, &iOff)
**       ){
**         // An instance of phrase iPhrase at offset iOff of column iCol
**       }
**
**   The Fts5PhraseIter structure is defined above. Applications should not
**   modify this structure directly - it should only be used as shown above
**   with the xPhraseFirst() and xPhraseNext() API methods (and by
**   xPhraseFirstColumn() and xPhraseNextColumn() as illustrated below).
**
**   This API can be quite slow if used with an FTS5 table created with the
**   "detail=none" or "detail=column" option. If the FTS5 table is created
**   with either "detail=none" or "detail=column" and "content=" option
**   (i.e. if it is a contentless table), then this API always iterates
**   through an empty set (all calls to xPhraseFirst() set iCol to -1).
**
** xPhraseNext()
**   See xPhraseFirst above.
**
** xPhraseFirstColumn()
**   This function and xPhraseNextColumn() are similar to the xPhraseFirst()
**   and xPhraseNext() APIs described above. The difference is that instead
**   of iterating through all instances of a phrase in the current row, these
**   APIs are used to iterate through the set of columns in the current row
**   that contain one or more instances of a specified phrase. For example:
**
**       Fts5PhraseIter iter;
**       int iCol;
**       for(pApi->xPhraseFirstColumn(pFts, iPhrase, &iter, &iCol);
**           iCol>=0;
**           pApi->xPhraseNextColumn(pFts, &iter, &iCol)
**       ){
**         // Column iCol contains at least one instance of phrase iPhrase
**       }
**
**   This API can be quite slow if used with an FTS5 table created with the
**   "detail=none" option. If the FTS5 table is created with either
**   "detail=none" "content=" option (i.e. if it is a contentless table),
**   then this API always iterates through an empty set (all calls to
**   xPhraseFirstColumn() set iCol to -1).
**
**   The information accessed using this API and its companion
**   xPhraseFirstColumn() may also be obtained using xPhraseFirst/xPhraseNext
**   (or xInst/xInstCount). The chief advantage of this API is that it is
**   significantly more efficient than those alternatives when used with
**   "detail=column" tables.
**
** xPhraseNextColumn()
**   See xPhraseFirstColumn above.
**
** xQueryToken(pFts5, iPhrase, iToken, ppToken, pnToken)
**   This is used to access token iToken of phrase iPhrase of the current
**   query. Before returning, output parameter *ppToken is set to point
**   to a buffer containing the requested token, and *pnToken to the
**   size of this buffer in bytes.
**
**   If iPhrase or iToken are less than zero, or if iPhrase is greater than
**   or equal to the number of phrases in the query as reported by
**   xPhraseCount(), or if iToken is equal to or greater than the number of
**   tokens in the phrase, SQLITE_RANGE is returned and *ppToken and *pnToken

	are both zeroed.

**
**   The output text is not a copy of the query text that specified the
**   token. It is the output of the tokenizer module. For tokendata=1
**   tables, this includes any embedded 0x00 and trailing data.
**
** xInstToken(pFts5, iIdx, iToken, ppToken, pnToken)
**   This is used to access token iToken of phrase hit iIdx within the
**   current row. If iIdx is less than zero or greater than or equal to the
**   value returned by xInstCount(), SQLITE_RANGE is returned.  Otherwise,
**   output variable (*ppToken) is set to point to a buffer containing the
**   matching document token, and (*pnToken) to the size of that buffer in
**   bytes. This API is not available if the specified token matches a
**   prefix query term. In that case both output variables are always set
**   to 0.
**
**   The output text is not a copy of the document text that was tokenized.
**   It is the output of the tokenizer module. For tokendata=1 tables, this
**   includes any embedded 0x00 and trailing data.
**
**   This API can be quite slow if used with an FTS5 table created with the
**   "detail=none" or "detail=column" option.

** Lookaside malloc is a set of fixed-size buffers that can be used
** to satisfy small transient memory allocation requests for objects
** associated with a particular database connection.  The use of
** lookaside malloc provides a significant performance enhancement
** (approx 10%) by avoiding numerous malloc/free requests while parsing
** SQL statements.
**
** The Lookaside structure holds configuration information about the
** lookaside malloc subsystem.  Each available memory allocation in
** the lookaside subsystem is stored on a linked list of LookasideSlot
** objects.
**
** Lookaside allocations are only allowed for objects that are associated
** with a particular database connection.  Hence, schema information cannot
** be stored in lookaside because in shared cache mode the schema information
** is shared by multiple database connections.  Therefore, while parsing
** schema information, the Lookaside.bEnabled flag is cleared so that
** lookaside allocations are not used to construct the schema objects.
**
** New lookaside allocations are only allowed if bDisable==0.  When
** bDisable is greater than zero, sz is set to zero which effectively
** disables lookaside without adding a new test for the bDisable flag
** in a performance-critical path.  sz should be set by to szTrue whenever
** bDisable changes back to zero.
**
** Lookaside buffers are initially held on the pInit list.  As they are
** used and freed, they are added back to the pFree list.  New allocations
** come off of pFree first, then pInit as a fallback.  This dual-list
** allows use to compute a high-water mark - the maximum number of allocations
** outstanding at any point in the past - by subtracting the number of
** allocations on the pInit list from the total number of allocations.
**
** Enhancement on 2019-12-12:  Two-size-lookaside
** The default lookaside configuration is 100 slots of 1200 bytes each.
** The larger slot sizes are important for performance, but they waste
** a lot of space, as most lookaside allocations are less than 128 bytes.
** The two-size-lookaside enhancement breaks up the lookaside allocation
** into two pools:  One of 128-byte slots and the other of the default size
** (1200-byte) slots.   Allocations are filled from the small-pool first,
** failing over to the full-size pool if that does not work.  Thus more
** lookaside slots are available while also using less memory.
** This enhancement can be omitted by compiling with
** SQLITE_OMIT_TWOSIZE_LOOKASIDE.

**
**   FUNCTION(zName, nArg, iArg, bNC, xFunc)

**     implemented by C function xFunc that accepts nArg arguments. The
**     value passed as iArg is cast to a (void*) and made available
**     as the user-data (sqlite3_user_data()) for the function. If
**     argument bNC is true, then the SQLITE_FUNC_NEEDCOLL flag is set.
**
**   VFUNCTION(zName, nArg, iArg, bNC, xFunc)
**     Like FUNCTION except it omits the SQLITE_FUNC_CONSTANT flag.
**
**   SFUNCTION(zName, nArg, iArg, bNC, xFunc)
**     Like FUNCTION except it omits the SQLITE_FUNC_CONSTANT flag and
**     adds the SQLITE_DIRECTONLY flag.
**
**   INLINE_FUNC(zName, nArg, iFuncId, mFlags)
**     zName is the name of a function that is implemented by in-line
**     byte code rather than by the usual callbacks. The iFuncId
**     parameter determines the function id.  The mFlags parameter is
**     optional SQLITE_FUNC_ flags for this function.
**
**   TEST_FUNC(zName, nArg, iFuncId, mFlags)
**     zName is the name of a test-only function implemented by in-line
**     byte code rather than by the usual callbacks. The iFuncId
**     parameter determines the function id.  The mFlags parameter is
**     optional SQLITE_FUNC_ flags for this function.
**
**   DFUNCTION(zName, nArg, iArg, bNC, xFunc)
**     Like FUNCTION except it omits the SQLITE_FUNC_CONSTANT flag and
**     adds the SQLITE_FUNC_SLOCHNG flag.  Used for date & time functions
**     and functions like sqlite_version() that can change, but not during
**     a single query.  The iArg is ignored.  The user-data is always set
**     to a NULL pointer.  The bNC parameter is not used.
**
**   MFUNCTION(zName, nArg, xPtr, xFunc)
**     For math-library functions.  xPtr is an arbitrary pointer.
**
**   PURE_DATE(zName, nArg, iArg, bNC, xFunc)
**     Used for "pure" date/time functions, this macro is like DFUNCTION
**     except that it does set the SQLITE_FUNC_CONSTANT flags.  iArg is
**     ignored and the user-data for these functions is set to an
**     arbitrary non-NULL pointer.  The bNC parameter is not used.
**
**   AGGREGATE(zName, nArg, iArg, bNC, xStep, xFinal)
**     Used to create an aggregate function definition implemented by
**     the C functions xStep and xFinal. The first four parameters
**     are interpreted in the same way as the first 4 parameters to
**     FUNCTION().
**
**   WAGGREGATE(zName, nArg, iArg, xStep, xFinal, xValue, xInverse)
**     Used to create an aggregate function definition implemented by
**     the C functions xStep and xFinal. The first four parameters
**     are interpreted in the same way as the first 4 parameters to
**     FUNCTION().
**
**   LIKEFUNC(zName, nArg, pArg, flags)
**     Used to create a scalar function definition of a function zName
**     that accepts nArg arguments and is implemented by a call to C
**     function likeFunc. Argument pArg is cast to a (void *) and made
**     available as the function user-data (sqlite3_user_data()). The
**     FuncDef.flags variable is set to the value passed as the flags
**     parameter.

** An object of this type is created for each virtual table present in

** instance of the sqlite3_vtab* handle used to access the virtual table
** implementation. sqlite3_vtab* handles can not be shared between
** database connections, even when the rest of the in-memory database
** schema is shared, as the implementation often stores the database
** connection handle passed to it via the xConnect() or xCreate() method
** during initialization internally. This database connection handle may
** then be used by the virtual table implementation to access real tables
** within the database. So that they appear as part of the callers
** transaction, these accesses need to be made via the same database
** connection as that used to execute SQL operations on the virtual table.
**
** All VTable objects that correspond to a single table in a shared
** database schema are initially stored in a linked-list pointed to by
** the Table.pVTable member variable of the corresponding Table object.
** When an sqlite3_prepare() operation is required to access the virtual
** table, it searches the list for the VTable that corresponds to the
** database connection doing the preparing so as to use the correct
** sqlite3_vtab* handle in the compiled query.
**
** When an in-memory Table object is deleted (for example when the
** schema is being reloaded for some reason), the VTable objects are not
** deleted and the sqlite3_vtab* handles are not xDisconnect()ed
** immediately. Instead, they are moved from the Table.pVTable list to
** another linked list headed by the sqlite3.pDisconnect member of the
** corresponding sqlite3 structure. They are then deleted/xDisconnected
** next time a statement is prepared using said sqlite3*. This is done
** to avoid deadlock issues involving multiple sqlite3.mutex mutexes.
** Refer to comments above function sqlite3VtabUnlockList() for an
** explanation as to why it is safe to add an entry to an sqlite3.pDisconnect
** list without holding the corresponding sqlite3.mutex mutex.

** fields, for the purposes of doing a comparison.
**
** A record is an object that contains one or more fields of data.
** Records are used to store the content of a table row and to store
** the key of an index.  A blob encoding of a record is created by
** the OP_MakeRecord opcode of the VDBE and is disassembled by the
** OP_Column opcode.
**
** An instance of this object serves as a "key" for doing a search on
** an index b+tree. The goal of the search is to find the entry that
** is closed to the key described by this object.  This object might hold
** just a prefix of the key.  The number of fields is given by
** pKeyInfo->nField.
**
** The r1 and r2 fields are the values to return if this key is less than
** or greater than a key in the btree, respectively.  These are normally
** -1 and +1 respectively, but might be inverted to +1 and -1 if the b-tree
** is in DESC order.
**
** The key comparison functions actually return default_rc when they find
** an equals comparison.  default_rc can be -1, 0, or +1.  If there are
** multiple entries in the b-tree with the same key (when only looking
** at the first pKeyInfo->nFields,) then default_rc can be set to -1 to
** cause the search to find the last match, or +1 to cause the search to
** find the first match.
**
** The key comparison functions will set eqSeen to true if they ever
** get and equal results when comparing this structure to a b-tree record.
** When default_rc!=0, the search might end up on the record immediately
** before the first match or immediately after the last match.  The
** eqSeen field will indicate whether or not an exact match exists in the
** b-tree.

/*
** Each SQL index is represented in memory by an
** instance of the following structure.
**
** The columns of the table that are to be indexed are described
** by the aiColumn[] field of this structure.  For example, suppose
** we have the following table and index:
**
**     CREATE TABLE Ex1(c1 int, c2 int, c3 text);
**     CREATE INDEX Ex2 ON Ex1(c3,c1);
**
** In the Table structure describing Ex1, nCol==3 because there are
** three columns in the table.  In the Index structure describing
** Ex2, nColumn==2 since 2 of the 3 columns of Ex1 are indexed.
** The value of aiColumn is {2, 0}.  aiColumn[0]==2 because the
** first column to be indexed (c3) has an index of 2 in Ex1.aCol[].
** The second column to be indexed (c1) has an index of 0 in
** Ex1.aCol[], hence Ex2.aiColumn[1]==0.
**
** The Index.onError field determines whether or not the indexed columns
** must be unique and what to do if they are not.  When Index.onError=OE_None,
** it means this is not a unique index.  Otherwise it is a unique index
** and the value of Index.onError indicates which conflict resolution
** algorithm to employ when an attempt is made to insert a non-unique
** element.
**
** The colNotIdxed bitmask is used in combination with SrcItem.colUsed
** for a fast test to see if an index can serve as a covering index.
** colNotIdxed has a 1 bit for every column of the original table that
** is *not* available in the index.  Thus the expression
** "colUsed & colNotIdxed" will be non-zero if the index is not a
** covering index.  The most significant bit of of colNotIdxed will always
** be true (note-20221022-a).  If a column beyond the 63rd column of the
** table is used, the "colUsed & colNotIdxed" test will always be non-zero
** and we have to assume either that the index is not covering, or use
** an alternative (slower) algorithm to determine whether or not
** the index is covering.
**
** While parsing a CREATE TABLE or CREATE INDEX statement in order to
** generate VDBE code (as opposed to parsing one read from an sqlite_schema
** table as part of parsing an existing database schema), transient instances
** of this structure may be created. In this case the Index.tnum variable is
** used to store the address of a VDBE instruction, not a database page
** number (it cannot - the database page is not allocated until the VDBE
** program is executed). See convertToWithoutRowidTable() for details.

** as opcodes here. For example, the parser defines TK_GE to be an integer
** code representing the ">=" operator. This same integer code is reused
** to represent the greater-than-or-equal-to operator in the expression
** tree.
**
** If the expression is an SQL literal (TK_INTEGER, TK_FLOAT, TK_BLOB,
** or TK_STRING), then Expr.u.zToken contains the text of the SQL literal. If
** the expression is a variable (TK_VARIABLE), then Expr.u.zToken contains the
** variable name. Finally, if the expression is an SQL function (TK_FUNCTION),
** then Expr.u.zToken contains the name of the function.
**
** Expr.pRight and Expr.pLeft are the left and right subexpressions of a
** binary operator. Either or both may be NULL.
**
** Expr.x.pList is a list of arguments if the expression is an SQL function,
** a CASE expression or an IN expression of the form "<lhs> IN (<y>, <z>...)".
** Expr.x.pSelect is used if the expression is a sub-select or an expression of
** the form "<lhs> IN (SELECT ...)". If the EP_xIsSelect bit is set in the
** Expr.flags mask, then Expr.x.pSelect is valid. Otherwise, Expr.x.pList is
** valid.
**
** An expression of the form ID or ID.ID refers to a column in a table.
** For such expressions, Expr.op is set to TK_COLUMN and Expr.iTable is
** the integer cursor number of a VDBE cursor pointing to that table and
** Expr.iColumn is the column number for the specific column.  If the
** expression is used as a result in an aggregate SELECT, then the
** value is also stored in the Expr.iAgg column in the aggregate so that
** it can be accessed after all aggregates are computed.
**
** If the expression is an unbound variable marker (a question mark
** character '?' in the original SQL) then the Expr.iTable holds the index
** number for that variable.
**
** If the expression is a subquery then Expr.iColumn holds an integer
** register number containing the result of the subquery.  If the
** subquery gives a constant result, then iTable is -1.  If the subquery
** gives a different answer at different times during statement processing
** then iTable is the address of a subroutine that computes the subquery.
**
** If the Expr is of type OP_Column, and the table it is selecting from
** is a disk table or the "old.*" pseudo-table, then pTab points to the
** corresponding table definition.
**
** ALLOCATION NOTES:
**
** Expr objects can use a lot of memory space in database schema.  To
** help reduce memory requirements, sometimes an Expr object will be
** truncated.  And to reduce the number of memory allocations, sometimes
** two or more Expr objects will be stored in a single memory allocation,
** together with Expr.u.zToken strings.
**
** If the EP_Reduced and EP_TokenOnly flags are set when
** an Expr object is truncated.  When EP_Reduced is set, then all
** the child Expr objects in the Expr.pLeft and Expr.pRight subtrees
** are contained within the same memory allocation.  Note, however, that
** the subtrees in Expr.x.pList or Expr.x.pSelect are always separately
** allocated, regardless of whether or not EP_Reduced is set.

**     SRT_Output      Generate a row of output (using the OP_ResultRow
**                     opcode) for each row in the result set.
**
**     SRT_Mem         Only valid if the result is a single column.
**                     Store the first column of the first result row
**                     in register pDest->iSDParm then abandon the rest
**                     of the query.  This destination implies "LIMIT 1".
**
**     SRT_Set         The result must be a single column.  Store each
**                     row of result as the key in table pDest->iSDParm.
**                     Apply the affinity pDest->affSdst before storing
**                     results.  Used to implement "IN (SELECT ...)".
**
**     SRT_EphemTab    Create an temporary table pDest->iSDParm and store
**                     the result there. The cursor is left open after
**                     returning.  This is like SRT_Table except that
**                     this destination uses OP_OpenEphemeral to create
**                     the table first.
**
**     SRT_Coroutine   Generate a co-routine that returns a new row of
**                     results each time it is invoked.  The entry point
**                     of the co-routine is stored in register pDest->iSDParm
**                     and the result row is stored in pDest->nDest registers
**                     starting with pDest->iSdst.
**
**     SRT_Table       Store results in temporary table pDest->iSDParm.
**     SRT_Fifo        This is like SRT_EphemTab except that the table
**                     is assumed to already be open.  SRT_Fifo has
**                     the additional property of being able to ignore
**                     the ORDER BY clause.
**
**     SRT_DistFifo    Store results in a temporary table pDest->iSDParm.
**                     But also use temporary table pDest->iSDParm+1 as
**                     a record of all prior results and ignore any duplicate
**                     rows.  Name means:  "Distinct Fifo".
**
**     SRT_Queue       Store results in priority queue pDest->iSDParm (really
**                     an index).  Append a sequence number so that all entries
**                     are distinct.
**
**     SRT_DistQueue   Store results in priority queue pDest->iSDParm only if
**                     the same record has never been stored before.  The
**                     index at pDest->iSDParm+1 hold all prior stores.
**
**     SRT_Upfrom      Store results in the temporary table already opened by
**                     pDest->iSDParm. If (pDest->iSDParm<0), then the temp
**                     table is an intkey table - in this case the first
**                     column returned by the SELECT is used as the integer
**                     key. If (pDest->iSDParm>0), then the table is an index
**                     table. (pDest->iSDParm) is the number of key columns in
**                     each index record in this case.

**                                If an equivalent interface exists by
**                                a different name, using a separate -D

** This file contains the C functions that implement a memory
** allocation subsystem for use by SQLite.
**
** This version of the memory allocation subsystem omits all
** use of malloc(). The application gives SQLite a block of memory
** before calling sqlite3_initialize() from which allocations
** are made and returned by the xMalloc() and xRealloc()
** implementations. Once sqlite3_initialize() has been called,
** the amount of memory available to SQLite is fixed and cannot
** be changed.
**
** This version of the memory allocation subsystem is included
** in the build only if SQLITE_ENABLE_MEMSYS5 is defined.
**
** This memory allocator uses the following algorithm:
**
**   1.  All memory allocation sizes are rounded up to a power of 2.
**
**   2.  If two adjacent free blocks are the halves of a larger block,
**       then the two blocks are coalesced into the single larger block.
**
**   3.  New memory is allocated from the first available free block.
**
** This algorithm is described in: J. M. Robson. "Bounds for Some Functions
** Concerning Dynamic Storage Allocation". Journal of the Association for
** Computing Machinery, Volume 21, Number 8, July 1974, pages 491-499.
**
** Let n be the size of the largest allocation divided by the minimum
** allocation size (after rounding all sizes up to a power of 2.)  Let M
** be the maximum amount of memory ever outstanding at one time.  Let
** N be the total amount of memory available for allocation.  Robson
** proved that this memory allocator will never breakdown due to
** fragmentation as long as the following constraint holds:
**
**      N >=  M*(1 + log2(n)/2) - n + 1
**
** The sqlite3_status() logic tracks the maximum values of n and M so
** that an application can, at any time, verify this constraint.

/******************************************************************************
*************************** Posix Advisory Locking ****************************
**
** POSIX advisory locks are broken by design.  ANSI STD 1003.1 (1996)
** section 6.5.2.2 lines 483 through 490 specify that when a process
** sets or clears a lock, that operation overrides any prior locks set
** by the same process.  It does not explicitly say so, but this implies
** that it overrides locks set by the same process using a different
** file descriptor.  Consider this test case:
**
**       int fd1 = open("./file1", O_RDWR|O_CREAT, 0644);
**       int fd2 = open("./file2", O_RDWR|O_CREAT, 0644);
**
** Suppose ./file1 and ./file2 are really the same file (because
** one is a hard or symbolic link to the other) then if you set
** an exclusive lock on fd1, then try to get an exclusive lock
** on fd2, it works.  I would have expected the second lock to
** fail since there was already a lock on the file due to fd1.
** But not so.  Since both locks came from the same process, the
** second overrides the first, even though they were on different
** file descriptors opened on different file names.
**
** This means that we cannot use POSIX locks to synchronize file access
** among competing threads of the same process.  POSIX locks will work fine
** to synchronize access for threads in separate processes, but not
** threads within the same process.
**
** To work around the problem, SQLite has to manage file locks internally
** on its own.  Whenever a new database is opened, we have to find the
** specific inode of the database file (the inode is determined by the
** st_dev and st_ino fields of the stat structure that fstat() fills in)
** and check for locks already existing on that inode.  When locks are
** created or removed, we have to look at our own internal record of the
** locks to see if another thread has previously set a lock on that same
** inode.
**
** (Aside: The use of inode numbers as unique IDs does not work on VxWorks.
** For VxWorks, we have to use the alternative unique ID system based on
** canonical filename and implemented in the previous division.)
**
** The sqlite3_file structure for POSIX is no longer just an integer file
** descriptor.  It is now a structure that holds the integer file
** descriptor and a pointer to a structure that describes the internal
** locks on the corresponding inode.  There is one locking structure
** per inode, so if the same inode is opened twice, both unixFile structures
** point to the same locking structure.  The locking structure keeps
** a reference count (so we will know when to delete it) and a "cnt"
** field that tells us its internal lock status.  cnt==0 means the
** file is unlocked.  cnt==-1 means the file has an exclusive lock.
** cnt>0 means there are cnt shared locks on the file.
**
** Any attempt to lock or unlock a file first checks the locking
** structure.  The fcntl() system call is only invoked to set a
** POSIX lock if the internal lock structure transitions between
** a locked and an unlocked state.
**
** But wait:  there are yet more problems with POSIX advisory locks.
**
** If you close a file descriptor that points to a file that has locks,
** all locks on that file that are owned by the current process are
** released.  To work around this problem, each unixInodeInfo object
** maintains a count of the number of pending locks on the inode.
** When an attempt is made to close an unixFile, if there are
** other unixFile open on the same inode that are holding locks, the call
** to close() the file descriptor is deferred until all of the locks clear.
** The unixInodeInfo structure keeps a list of file descriptors that need to
** be closed and that list is walked (and cleared) when the last lock
** clears.
**
** Yet another problem:  LinuxThreads do not play well with posix locks.
**
** Many older versions of linux use the LinuxThreads library which is
** not posix compliant.  Under LinuxThreads, a lock created by thread
** A cannot be modified or overridden by a different thread B.
** Only thread A can modify the lock.  Locking behavior is correct
** if the application uses the newer Native Posix Thread Library (NPTL)
** on linux - with NPTL a lock created by thread A can override locks
** in thread B.  But there is no way to know at compile-time which
** threading library is being used.  So there is no way to know at
** compile-time whether or not thread A can override locks on thread B.
** One has to do a run-time check to discover the behavior of the
** current process.
**
** SQLite used to support LinuxThreads.  But support for LinuxThreads
** was dropped beginning with version 3.7.0.  SQLite will still work with
** LinuxThreads provided that (1) there is no more than one connection
** per database file in the same process and (2) database connections
** do not move across threads.

	 ** confusion with SQLite lock names). The algorithms are complicated
	 ** slightly in order to be compatible with Windows95 systems simultaneously
	 ** accessing the same database file, in case that is ever required.
	 **
	 ** Symbols defined in os.h identify the 'pending byte' and the 'reserved
	 ** byte', each single bytes at well known offsets, and the 'shared byte
	 ** range', a range of 510 bytes at a well known offset.
	 **
	 ** To obtain a SHARED lock, a read-lock is obtained on the 'pending
	 ** byte'.  If this is successful, 'shared byte range' is read-locked
	 ** and the lock on the 'pending byte' released.  (Legacy note:  When
	 ** SQLite was first developed, Windows95 systems were still very common,
	 ** and Windows95 lacks a shared-lock capability.  So on Windows95, a
	 ** single randomly selected by from the 'shared byte range' is locked.
	 ** Windows95 is now pretty much extinct, but this work-around for the
	 ** lack of shared-locks on Windows95 lives on, for backwards
	 ** compatibility.)
	 **
	 ** A process may only obtain a RESERVED lock after it has a SHARED lock.
	 ** A RESERVED lock is implemented by grabbing a write-lock on the
	 ** 'reserved byte'.
	 **
	 ** An EXCLUSIVE lock may only be requested after either a SHARED or
	 ** RESERVED lock is held. An EXCLUSIVE lock is implemented by obtaining
	 ** a write-lock on the entire 'shared byte range'. Since all other locks
	 ** require a read-lock on one of the bytes within this range, this ensures
	 ** that no other locks are held on the database.
	 **
	 ** If a process that holds a RESERVED lock requests an EXCLUSIVE, then
	 ** a PENDING lock is obtained first. A PENDING lock is implemented by
	 ** obtaining a write-lock on the 'pending byte'. This ensures that no new
	 ** SHARED locks can be obtained, but existing SHARED locks are allowed to
	 ** persist. If the call to this function fails to obtain the EXCLUSIVE
	 ** lock in this case, it holds the PENDING lock instead. The client may
	 ** then re-attempt the EXCLUSIVE lock later on, after existing SHARED

** We could coalesce this object into unixInodeInfo, but that would mean
** every open file that does not use shared memory (in other words, most
** open files) would have to carry around this extra information.  So
** the unixInodeInfo object contains a pointer to this unixShmNode object
** and the unixShmNode object is created only when needed.
**
** unixMutexHeld() must be true when creating or destroying
** this object or while reading or writing the following fields:
**
**      nRef
**
** The following fields are read-only after the object is created:
**
**      hShm
**      zFilename

**   locks are held by the process on this slot. If it is set to -1, then
**   some client holds an EXCLUSIVE lock on the locking slot. If the aLock[]
**   value is set to a positive value, then it is the number of shared
**   locks currently held on the slot.
**
** aMutex[SQLITE_SHM_NLOCK]:
**   Normally, when SQLITE_ENABLE_SETLK_TIMEOUT is not defined, mutex
**   pShmMutex is used to protect the aLock[] array and the right to
**   call fcntl() on unixShmNode.hShm to obtain or release locks.
**
**   If SQLITE_ENABLE_SETLK_TIMEOUT is defined though, we use an array
**   of mutexes - one for each locking slot. To read or write locking
**   slot aLock[iSlot], the caller must hold the corresponding mutex
**   aMutex[iSlot]. Similarly, to call fcntl() to obtain or release a

//	** file with the "-shm" suffix added.  For example, if the database file
//	** is "/home/user1/config.db" then the file that is created and mmapped
//	** for shared memory will be called "/home/user1/config.db-shm".
//	**
//	** Another approach to is to use files in /dev/shm or /dev/tmp or an
//	** some other tmpfs mount. But if a file in a different directory
//	** from the database file is used, then differing access permissions
//	** or a chroot() might cause two different processes on the same
//	** database to end up using different files for shared memory -
//	** meaning that their memory would not really be shared - resulting
//	** in database corruption.  Nevertheless, this tmpfs file usage
//	** can be enabled at compile-time using -DSQLITE_SHM_DIRECTORY="/dev/shm"
//	** or the equivalent.  The use of the SQLITE_SHM_DIRECTORY compile-time
//	** option results in an incompatible build of SQLite;  builds of SQLite
//	** that with differing SQLITE_SHM_DIRECTORY settings attempt to use the
//	** same database file at the same time, database corruption will likely
//	** result. The SQLITE_SHM_DIRECTORY compile-time option is considered
//	** "unsupported" and may go away in a future SQLite release.
//	**
//	** When opening a new shared-memory file, if no other instances of that
//	** file are currently open, in this process or in other processes, then
//	** the file must be truncated to zero length or have its header cleared.
//	**
//	** If the original database file (pDbFd) is using the "unix-excl" VFS
//	** that means that an exclusive lock is held on the database file and
//	** that no other processes are able to read or write the database.  In
//	** that case, we do not really need shared memory.  No shared memory

** This division contains definitions of sqlite3_io_methods objects that

**

** A pointer to the F pointer is used as the pAppData value for VFS
** objects.  We have to do this instead of letting pAppData point
** directly at the finder-function since C90 rules prevent a void*

** and writers [http://sqlite.org/lockingv3.html].  The five file locking
** states (UNLOCKED, PENDING, SHARED, RESERVED, EXCLUSIVE) are implemented
** as POSIX read & write locks over fixed set of locations (via fsctl),
** on AFP and SMB only exclusive byte-range locks are available via fsctl
** with _IOWR('z', 23, struct ByteRangeLockPB2) to track the same 5 states.
** To simulate a F_RDLCK on the shared range, on AFP a randomly selected
** address in the shared range is taken for a SHARED lock, the entire
** shared range is taken for an EXCLUSIVE lock):
**
**      PENDING_BYTE        0x40000000
**      RESERVED_BYTE       0x40000001
**      SHARED_RANGE        0x40000002 -> 0x40000200
**
** This works well on the local file system, but shows a nearly 100x
** slowdown in read performance on AFP because the AFP client disables
** the read cache when byte-range locks are present.  Enabling the read
** cache exposes a cache coherency problem that is present on all OS X
** supported network file systems.  NFS and AFP both observe the
** close-to-open semantics for ensuring cache coherency
** [http://nfs.sourceforge.net/#faq_a8], which does not effectively
** address the requirements for concurrent database access by multiple
** readers and writers
** [http://www.nabble.com/SQLite-on-NFS-cache-coherency-td15655701.html].
**
** To address the performance and cache coherency issues, proxy file locking
** changes the way database access is controlled by limiting access to a
** single host at a time and moving file locks off of the database file
** and onto a proxy file on the local file system.
**
**
** Using proxy locks
** -----------------
**
** C APIs
**
**  sqlite3_file_control(db, dbname, SQLITE_FCNTL_SET_LOCKPROXYFILE,
**                       <proxy_path> | ":auto:");
**  sqlite3_file_control(db, dbname, SQLITE_FCNTL_GET_LOCKPROXYFILE,
**                       &<proxy_path>);
**
**
** SQL pragmas
**
**  PRAGMA [database.]lock_proxy_file=<proxy_path> | :auto:
**  PRAGMA [database.]lock_proxy_file
**
** Specifying ":auto:" means that if there is a conch file with a matching
** host ID in it, the proxy path in the conch file will be used, otherwise
** a proxy path based on the user's temp dir
** (via confstr(_CS_DARWIN_USER_TEMP_DIR,...)) will be used and the
** actual proxy file name is generated from the name and path of the
** database file.  For example:
**
**       For database path "/Users/me/foo.db"
**       The lock path will be "<tmpdir>/sqliteplocks/_Users_me_foo.db:auto:")
**
** Once a lock proxy is configured for a database connection, it can not
** be removed, however it may be switched to a different proxy path via
** the above APIs (assuming the conch file is not being held by another
** connection or process).
**
**
** How proxy locking works
** -----------------------
**
** Proxy file locking relies primarily on two new supporting files:
**
**   *  conch file to limit access to the database file to a single host
**      at a time
**
**   *  proxy file to act as a proxy for the advisory locks normally
**      taken on the database
**
** The conch file - to use a proxy file, sqlite must first "hold the conch"
** by taking an sqlite-style shared lock on the conch file, reading the
** contents and comparing the host's unique host ID (see below) and lock
** proxy path against the values stored in the conch.  The conch file is
** stored in the same directory as the database file and the file name
** is patterned after the database file name as ".<databasename>-conch".
** If the conch file does not exist, or its contents do not match the
** host ID and/or proxy path, then the lock is escalated to an exclusive
** lock and the conch file contents is updated with the host ID and proxy
** path and the lock is downgraded to a shared lock again.  If the conch
** is held by another process (with a shared lock), the exclusive lock
** will fail and SQLITE_BUSY is returned.
**
** The proxy file - a single-byte file used for all advisory file locks
** normally taken on the database file.   This allows for safe sharing
** of the database file for multiple readers and writers on the same
** host (the conch ensures that they all use the same local lock file).
**
** Requesting the lock proxy does not immediately take the conch, it is
** only taken when the first request to lock database file is made.
** This matches the semantics of the traditional locking behavior, where
** opening a connection to a database file does not take a lock on it.
** The shared lock and an open file descriptor are maintained until
** the connection to the database is closed.
**
** The proxy file and the lock file are never deleted so they only need
** to be created the first time they are used.
**
** Configuration options
** ---------------------
**
**  SQLITE_PREFER_PROXY_LOCKING
**
**       Database files accessed on non-local file systems are
**       automatically configured for proxy locking, lock files are
**       named automatically using the same logic as
**       PRAGMA lock_proxy_file=":auto:"
**
**  SQLITE_PROXY_DEBUG
**
**       Enables the logging of error messages during host id file
**       retrieval and creation
**
**  LOCKPROXYDIR
**
**       Overrides the default directory used for lock proxy files that
**       are named automatically via the ":auto:" setting
**
**  SQLITE_DEFAULT_PROXYDIR_PERMISSIONS
**
**       Permissions to use when creating a directory for storing the
**       lock proxy files, only used when LOCKPROXYDIR is not set.
**
**
** As mentioned above, when compiled with SQLITE_PREFER_PROXY_LOCKING,
** setting the environment variable SQLITE_FORCE_PROXY_LOCKING to 1 will
** force proxy locking to be used for every database file opened, and 0
** will force automatic proxy locking to be disabled for all database
** files (explicitly calling the SQLITE_FCNTL_SET_LOCKPROXYFILE pragma or
** sqlite_file_control API is not affected by SQLITE_FORCE_PROXY_LOCKING).
 */

/*
** Proxy locking is only available on MacOSX
 */
/*
** The proxy locking style is intended for use with AFP filesystems.
** And since AFP is only supported on MacOSX, the proxy locking is also
** restricted to MacOSX.

** This file implements an object that represents a fixed-length
** bitmap.  Bits are numbered starting with 1.
**
** A bitmap is used to record which pages of a database file have been
** journalled during a transaction, or which pages have the "dont-write"
** property.  Usually only a few pages are meet either condition.
** So the bitmap is usually sparse and has low cardinality.
** But sometimes (for example when during a DROP of a large table) most
** or all of the pages in a database can get journalled.  In those cases,
** the bitmap becomes dense with high cardinality.  The algorithm needs
** to handle both cases well.
**
** The size of the bitmap is fixed when the object is created.
**
** All bits are clear when the bitmap is created.  Individual bits
** may be set or cleared one at a time.
**
** Test operations are about 100 times more common that set operations.
** Clear operations are exceedingly rare.  There are usually between
** 5 and 500 set operations per Bitvec object, though the number of sets can
** sometimes grow into tens of thousands or larger.  The size of the
** Bitvec object is the number of pages in the database file at the
** start of a transaction, and is thus usually less than a few thousand,
** but can be as large as 2 billion for a really big database.

** A complete page cache is an instance of this structure.  Every

**
** A page cache entry is "clean" if it exactly matches what is currently
** on disk.  A page is "dirty" if it has been modified and needs to be
** persisted to disk.
**
** pDirty, pDirtyTail, pSynced:
**   All dirty pages are linked into the doubly linked list using
**   PgHdr.pDirtyNext and pDirtyPrev. The list is maintained in LRU order
**   such that p was added to the list more recently than p->pDirtyNext.
**   PCache.pDirty points to the first (newest) element in the list and
**   pDirtyTail to the last (oldest).
**
**   The PCache.pSynced variable is used to optimize searching for a dirty
**   page to eject from the cache mid-transaction. It is better to eject
**   a page that does not require a journal sync than one that does.
**   Therefore, pSynced is maintained so that it *almost* always points
**   to either the oldest page in the pDirty/pDirtyTail list that has a
**   clear PGHDR_NEED_SYNC flag or to a page that is older than this one
**   (so that the right page to eject can be found by following pDirtyPrev

*************************************************************************
**
** This file implements the default page cache implementation (the
** sqlite3_pcache interface). It also contains part of the implementation
** of the SQLITE_CONFIG_PAGECACHE and sqlite3_release_memory() features.
** If the default page cache implementation is overridden, then neither of
** these two features are available.
**
** A Page cache line looks like this:
**
**  -------------------------------------------------------------
**  |  database page content   |  PgHdr1  |  MemPage  |  PgHdr  |
**  -------------------------------------------------------------
**
** The database page content is up front (so that buffer overreads tend to
** flow harmlessly into the PgHdr1, MemPage, and PgHdr extensions).   MemPage
** is the extension added by the btree.c module containing information such
** as the database page number and how that database page is used.  PgHdr
** is added by the pcache.c layer and contains information used to keep track
** of which pages are "dirty".  PgHdr1 is an extension added by this
** module (pcache1.c).  The PgHdr1 header is a subclass of sqlite3_pcache_page.
** PgHdr1 contains information needed to look up a page by its page number.
** The superclass sqlite3_pcache_page.pBuf points to the start of the
** database page content and sqlite3_pcache_page.pExtra points to PgHdr.
**
** The size of the extension (MemPage+PgHdr+PgHdr1) can be determined at
** runtime using sqlite3_config(SQLITE_CONFIG_PCACHE_HDRSZ, &size).  The
** sizes of the extensions sum to 272 bytes on x64 for 3.8.10, but this
** size can vary according to architecture, compile-time options, and
** SQLite library version number.
**
** Historical note:  It used to be that if the SQLITE_PCACHE_SEPARATE_HEADER
** was defined, then the page content would be held in a separate memory
** allocation from the PgHdr1.  This was intended to avoid clownshoe memory
** allocations.  However, the btree layer needs a small (16-byte) overrun
** area after the page content buffer.  The header serves as that overrun
** area.  Therefore SQLITE_PCACHE_SEPARATE_HEADER was discontinued to avoid
** any possibility of a memory error.
**
** This module tracks pointers to PgHdr1 objects.  Only pcache.c communicates
** with this module.  Information is passed back and forth as PgHdr1 pointers.
**
** The pcache.c and pager.c modules deal pointers to PgHdr objects.
** The btree.c module deals with pointers to MemPage objects.
**
** SOURCE OF PAGE CACHE MEMORY:
**
** Memory for a page might come from any of three sources:
**
**    (1)  The general-purpose memory allocator - sqlite3Malloc()
**    (2)  Global page-cache memory provided using sqlite3_config() with
**         SQLITE_CONFIG_PAGECACHE.
**    (3)  PCache-local bulk allocation.
**
** The third case is a chunk of heap memory (defaulting to 100 pages worth)
** that is allocated when the page cache is created.  The size of the local
** bulk allocation can be adjusted using
**
**     sqlite3_config(SQLITE_CONFIG_PAGECACHE, (void*)0, 0, N).
**
** If N is positive, then N pages worth of memory are allocated using a single
** sqlite3Malloc() call and that memory is used for the first N pages allocated.
** Or if N is negative, then -1024*N bytes of memory are allocated and used
** for as many pages as can be accommodated.
**
** Only one of (2) or (3) can be used.  Once the memory available to (2) or
** (3) is exhausted, subsequent allocations fail over to the general-purpose
** memory allocator (1).
**
** Earlier versions of SQLite used only methods (1) and (2).  But experiments
** show that method (3) with N==100 provides about a 5% performance boost for
** common workloads.

** read a few bytes (no more than 16 bytes) past the end of the page buffer.
** It will only read past the end of the page buffer, never write.  This
** object is positioned immediately after the page buffer to serve as an
** overrun area, so that overreads are harmless.
**
** Variables isBulkLocal and isAnchor were once type "u8". That works,
** but causes a 2-byte gap in the structure for most architectures (since
** pointers must be either 4 or 8-byte aligned). As this structure is located
** in memory directly after the associated page data, if the database is
** corrupt, code at the b-tree layer may overread the page buffer and
** read part of this structure before the corruption is detected. This
** can cause a valgrind error if the uninitialized gap is accessed. Using u16
** ensures there is no such gap, and therefore no bytes of uninitialized
** memory in the structure.
**
** The pLruNext and pLruPrev pointers form a double-linked circular list
** of all pages that are unpinned.  The PGroup.lru element (which should be
** the only element on the list with PgHdr1.isAnchor set to 1) forms the

*************************************************************************
**
** This module implements an object we call a "RowSet".
**
** The RowSet object is a collection of rowids.  Rowids
** are inserted into the RowSet in an arbitrary order.  Inserts
** can be intermixed with tests to see if a given rowid has been
** previously inserted into the RowSet.
**
** After all inserts are finished, it is possible to extract the
** elements of the RowSet in sorted order.  Once this extraction
** process has started, no new elements may be inserted.
**
** Hence, the primitive operations for a RowSet are:
**
**    CREATE
**    INSERT
**    TEST
**    SMALLEST
**    DESTROY
**
** The CREATE and DESTROY primitives are the constructor and destructor,
** obviously.  The INSERT primitive adds a new element to the RowSet.
** TEST checks to see if an element is already in the RowSet.  SMALLEST
** extracts the least value from the RowSet.
**
** The INSERT primitive might allocate additional memory.  Memory is
** allocated in chunks so most INSERTs do no allocation.  There is an
** upper bound on the size of allocated memory.  No memory is freed
** until DESTROY.
**
** The TEST primitive includes a "batch" number.  The TEST primitive
** will only see elements that were inserted before the last change
** in the batch number.  In other words, if an INSERT occurs between
** two TESTs where the TESTs have the same batch number, then the
** value added by the INSERT will not be visible to the second TEST.
** The initial batch number is zero, so if the very first TEST contains
** a non-zero batch number, it will see all prior INSERTs.
**
** No INSERTs may occurs after a SMALLEST.  An assertion will fail if
** that is attempted.
**
** The cost of an INSERT is roughly constant.  (Sometimes new memory
** has to be allocated on an INSERT.)  The cost of a TEST with a new
** batch number is O(NlogN) where N is the number of elements in the RowSet.
** The cost of a TEST using the same batch number is O(logN).  The cost
** of the first SMALLEST is O(NlogN).  Second and subsequent SMALLEST
** primitives are constant time.  The cost of DESTROY is O(N).
**
** TEST and SMALLEST may not be used by the same RowSet.  This used to
** be possible, but the feature was not used, so it was removed in order
** to simplify the code.

/******************* NOTES ON THE DESIGN OF THE PAGER ************************
**
** This comment block describes invariants that hold when using a rollback
** journal.  These invariants do not apply for journal_mode=WAL,
** journal_mode=MEMORY, or journal_mode=OFF.
**
** Within this comment block, a page is deemed to have been synced
** automatically as soon as it is written when PRAGMA synchronous=OFF.
** Otherwise, the page is not synced until the xSync method of the VFS
** is called successfully on the file containing the page.
**
** Definition:  A page of the database file is said to be "overwriteable" if
** one or more of the following are true about the page:
**
**     (a)  The original content of the page as it was at the beginning of
**          the transaction has been written into the rollback journal and
**          synced.
**
**     (b)  The page was a freelist leaf page at the start of the transaction.
**
**     (c)  The page number is greater than the largest page that existed in
**          the database file at the start of the transaction.
**
** (1) A page of the database file is never overwritten unless one of the
**     following are true:
**
**     (a) The page and all other pages on the same sector are overwriteable.
**
**     (b) The atomic page write optimization is enabled, and the entire
**         transaction other than the update of the transaction sequence
**         number consists of a single page change.
**
** (2) The content of a page written into the rollback journal exactly matches
**     both the content in the database when the rollback journal was written
**     and the content in the database at the beginning of the current
**     transaction.
**
** (3) Writes to the database file are an integer multiple of the page size
**     in length and are aligned on a page boundary.
**
** (4) Reads from the database file are either aligned on a page boundary and
**     an integer multiple of the page size in length or are taken from the
**     first 100 bytes of the database file.
**
** (5) All writes to the database file are synced prior to the rollback journal
**     being deleted, truncated, or zeroed.
**
** (6) If a super-journal file is used, then all writes to the database file
**     are synced prior to the super-journal being deleted.
**
** Definition: Two databases (or the same database at two points it time)
** are said to be "logically equivalent" if they give the same answer to
** all queries.  Note in particular the content of freelist leaf
** pages can be changed arbitrarily without affecting the logical equivalence
** of the database.
**
** (7) At any time, if any subset, including the empty set and the total set,
**     of the unsynced changes to a rollback journal are removed and the
**     journal is rolled back, the resulting database file will be logically
**     equivalent to the database file at the beginning of the transaction.
**
** (8) When a transaction is rolled back, the xTruncate method of the VFS
**     is called to restore the database file to the same size it was at
**     the beginning of the transaction.  (In some VFSes, the xTruncate
**     method is a no-op, but that does not change the fact the SQLite will
**     invoke it.)
**
** (9) Whenever the database file is modified, at least one bit in the range
**     of bytes from 24 through 39 inclusive will be changed prior to releasing
**     the EXCLUSIVE lock, thus signaling other connections on the same
**     database to flush their caches.
**
** (10) The pattern of bits in bytes 24 through 39 shall not repeat in less
**      than one billion transactions.
**
** (11) A database file is well-formed at the beginning and at the conclusion
**      of every transaction.
**
** (12) An EXCLUSIVE lock is held on the database file when writing to
**      the database file.
**
** (13) A SHARED lock is held on the database file while reading any
**      content out of the database file.

**
**
**  OPEN:
**
**    The pager starts up in this state. Nothing is guaranteed in this
**    state - the file may or may not be locked and the database size is
**    unknown. The database may not be read or written.
**
**    * No read or write transaction is active.
**    * Any lock, or no lock at all, may be held on the database file.
**    * The dbSize, dbOrigSize and dbFileSize variables may not be trusted.
**
**  READER:
**
**    In this state all the requirements for reading the database in
**    rollback (non-WAL) mode are met. Unless the pager is (or recently
**    was) in exclusive-locking mode, a user-level read transaction is
**    open. The database size is known in this state.
**
**    A connection running with locking_mode=normal enters this state when
**    it opens a read-transaction on the database and returns to state
**    OPEN after the read-transaction is completed. However a connection
**    running in locking_mode=exclusive (including temp databases) remains in
**    this state even after the read-transaction is closed. The only way
**    a locking_mode=exclusive connection can transition from READER to OPEN
**    is via the ERROR state (see below).
**
**    * A read transaction may be active (but a write-transaction cannot).
**    * A SHARED or greater lock is held on the database file.
**    * The dbSize variable may be trusted (even if a user-level read
**      transaction is not active). The dbOrigSize and dbFileSize variables
**      may not be trusted at this point.
**    * If the database is a WAL database, then the WAL connection is open.
**    * Even if a read-transaction is not open, it is guaranteed that
**      there is no hot-journal in the file-system.
**
**  WRITER_LOCKED:
**
**    The pager moves to this state from READER when a write-transaction
**    is first opened on the database. In WRITER_LOCKED state, all locks
**    required to start a write-transaction are held, but no actual
**    modifications to the cache or database have taken place.
**
**    In rollback mode, a RESERVED or (if the transaction was opened with
**    BEGIN EXCLUSIVE) EXCLUSIVE lock is obtained on the database file when
**    moving to this state, but the journal file is not written to or opened
**    to in this state. If the transaction is committed or rolled back while
**    in WRITER_LOCKED state, all that is required is to unlock the database
**    file.
**
**    IN WAL mode, WalBeginWriteTransaction() is called to lock the log file.
**    If the connection is running with locking_mode=exclusive, an attempt
**    is made to obtain an EXCLUSIVE lock on the database file.
**
**    * A write transaction is active.
**    * If the connection is open in rollback-mode, a RESERVED or greater
**      lock is held on the database file.
**    * If the connection is open in WAL-mode, a WAL write transaction
**      is open (i.e. sqlite3WalBeginWriteTransaction() has been successfully
**      called).
**    * The dbSize, dbOrigSize and dbFileSize variables are all valid.
**    * The contents of the pager cache have not been modified.
**    * The journal file may or may not be open.
**    * Nothing (not even the first header) has been written to the journal.
**
**  WRITER_CACHEMOD:
**
**    A pager moves from WRITER_LOCKED state to this state when a page is
**    first modified by the upper layer. In rollback mode the journal file
**    is opened (if it is not already open) and a header written to the
**    start of it. The database file on disk has not been modified.
**
**    * A write transaction is active.
**    * A RESERVED or greater lock is held on the database file.
**    * The journal file is open and the first header has been written
**      to it, but the header has not been synced to disk.
**    * The contents of the page cache have been modified.
**
**  WRITER_DBMOD:
**
**    The pager transitions from WRITER_CACHEMOD into WRITER_DBMOD state
**    when it modifies the contents of the database file. WAL connections
**    never enter this state (since they do not modify the database file,
**    just the log file).
**
**    * A write transaction is active.
**    * An EXCLUSIVE or greater lock is held on the database file.
**    * The journal file is open and the first header has been written
**      and synced to disk.
**    * The contents of the page cache have been modified (and possibly
**      written to disk).
**
**  WRITER_FINISHED:
**
**    It is not possible for a WAL connection to enter this state.
**
**    A rollback-mode pager changes to WRITER_FINISHED state from WRITER_DBMOD
**    state after the entire transaction has been successfully written into the
**    database file. In this state the transaction may be committed simply
**    by finalizing the journal file. Once in WRITER_FINISHED state, it is
**    not possible to modify the database further. At this point, the upper
**    layer must either commit or rollback the transaction.
**
**    * A write transaction is active.
**    * An EXCLUSIVE or greater lock is held on the database file.
**    * All writing and syncing of journal and database data has finished.
**      If no error occurred, all that remains is to finalize the journal to
**      commit the transaction. If an error did occur, the caller will need
**      to rollback the transaction.
**
**  ERROR:
**
**    The ERROR state is entered when an IO or disk-full error (including
**    SQLITE_IOERR_NOMEM) occurs at a point in the code that makes it
**    difficult to be sure that the in-memory pager state (cache contents,
**    db size etc.) are consistent with the contents of the file-system.
**
**    Temporary pager files may enter the ERROR state, but in-memory pagers
**    cannot.
**
**    For example, if an IO error occurs while performing a rollback,
**    the contents of the page-cache may be left in an inconsistent state.
**    At this point it would be dangerous to change back to READER state
**    (as usually happens after a rollback). Any subsequent readers might
**    report database corruption (due to the inconsistent cache), and if
**    they upgrade to writers, they may inadvertently corrupt the database
**    file. To avoid this hazard, the pager switches into the ERROR state
**    instead of READER following such an error.
**
**    Once it has entered the ERROR state, any attempt to use the pager
**    to read or write data returns an error. Eventually, once all
**    outstanding transactions have been abandoned, the pager is able to
**    transition back to OPEN state, discarding the contents of the
**    page-cache and any other in-memory state at the same time. Everything
**    is reloaded from disk (and, if necessary, hot-journal rollback performed)
**    when a read-transaction is next opened on the pager (transitioning
**    the pager into READER state). At that point the system has recovered
**    from the error.
**
**    Specifically, the pager jumps into the ERROR state if:
**
**      1. An error occurs while attempting a rollback. This happens in
**         function sqlite3PagerRollback().
**
**      2. An error occurs while attempting to finalize a journal file
**         following a commit in function sqlite3PagerCommitPhaseTwo().
**
**      3. An error occurs while attempting to write to the journal or
**         database file in function pagerStress() in order to free up
**         memory.
**
**    In other cases, the error is returned to the b-tree layer. The b-tree
**    layer then attempts a rollback operation. If the error condition
**    persists, the pager enters the ERROR state via condition (1) above.
**
**    Condition (3) is necessary because it can be triggered by a read-only
**    statement executed within a transaction. In this case, if the error
**    code were simply returned to the user, the b-tree layer would not
**    automatically attempt a rollback, as it assumes that an error in a
**    read-only statement cannot leave the pager in an internally inconsistent
**    state.
**
**    * The Pager.errCode variable is set to something other than SQLITE_OK.
**    * There are one or more outstanding references to pages (after the
**      last reference is dropped the pager should move back to OPEN state).
**    * The pager is not an in-memory pager.
**
**
** Notes:
**
**   * A pager is never in WRITER_DBMOD or WRITER_FINISHED state if the
**     connection is open in WAL mode. A WAL connection is always in one
**     of the first four states.
**
**   * Normally, a connection open in exclusive mode is never in PAGER_OPEN
**     state. There are two exceptions: immediately after exclusive-mode has
**     been turned on (and before any read or write transactions are
**     executed), and when the pager is leaving the "error state".
**
**   * See also: assert_pager_state().

/*
** The Pager.eLock variable is almost always set to one of the
** following locking-states, according to the lock currently held on
** the database file: NO_LOCK, SHARED_LOCK, RESERVED_LOCK or EXCLUSIVE_LOCK.
** This variable is kept up to date as locks are taken and released by
** the pagerLockDb() and pagerUnlockDb() wrappers.
**
** If the VFS xLock() or xUnlock() returns an error other than SQLITE_BUSY
** (i.e. one of the SQLITE_IOERR subtypes), it is not clear whether or not
** the operation was successful. In these circumstances pagerLockDb() and
** pagerUnlockDb() take a conservative approach - eLock is always updated
** when unlocking the file, and only updated when locking the file if the
** VFS call is successful. This way, the Pager.eLock variable may be set
** to a less exclusive (lower) value than the lock that is actually held
** at the system level, but it is never set to a more exclusive value.
**
** This is usually safe. If an xUnlock fails or appears to fail, there may
** be a few redundant xLock() calls or a lock may be held for longer than
** required, but nothing really goes wrong.
**
** The exception is when the database file is unlocked as the pager moves
** from ERROR to OPEN state. At this point there may be a hot-journal file
** in the file-system that needs to be rolled back (as part of an OPEN->SHARED
** transition, by the same pager or any other). If the call to xUnlock()
** fails at this point and the pager is left holding an EXCLUSIVE lock, this
** can confuse the call to xCheckReservedLock() call made later as part
** of hot-journal detection.
**
** xCheckReservedLock() is defined as returning true "if there is a RESERVED
** lock held by this process or any others". So xCheckReservedLock may
** return true because the caller itself is holding an EXCLUSIVE lock (but
** doesn't know it because of a previous error in xUnlock). If this happens
** a hot-journal may be mistaken for a journal being created by an active
** transaction in another process, causing SQLite to read from the database
** without rolling it back.
**
** To work around this, if a call to xUnlock() fails when unlocking the
** database in the ERROR state, Pager.eLock is set to UNKNOWN_LOCK. It
** is only changed back to a real locking state after a successful call
** to xLock(EXCLUSIVE). Also, the code to do the OPEN->SHARED state transition
** omits the check for a hot-journal if Pager.eLock is set to UNKNOWN_LOCK
** lock. Instead, it assumes a hot-journal exists and obtains an EXCLUSIVE
** lock on the database file before attempting to roll it back. See function
** PagerSharedLock() for more detail.
**
** Pager.eLock may only be set to UNKNOWN_LOCK when the pager is in
** PAGER_OPEN state.

/*
** Bits of the Pager.doNotSpill flag.  See further description below.
 */

/*
** An open page cache is an instance of struct Pager. A description of
** some of the more important member variables follows:
**
** eState
**
**   The current 'state' of the pager object. See the comment and state
**   diagram above for a description of the pager state.
**
** eLock
**
**   For a real on-disk database, the current lock held on the database file -
**   NO_LOCK, SHARED_LOCK, RESERVED_LOCK or EXCLUSIVE_LOCK.
**
**   For a temporary or in-memory database (neither of which require any
**   locks), this variable is always set to EXCLUSIVE_LOCK. Since such
**   databases always have Pager.exclusiveMode==1, this tricks the pager
**   logic into thinking that it already has all the locks it will ever
**   need (and no reason to release them).
**
**   In some (obscure) circumstances, this variable may also be set to
**   UNKNOWN_LOCK. See the comment above the #define of UNKNOWN_LOCK for
**   details.
**
** changeCountDone
**
**   This boolean variable is used to make sure that the change-counter
**   (the 4-byte header field at byte offset 24 of the database file) is
**   not updated more often than necessary.
**
**   It is set to true when the change-counter field is updated, which
**   can only happen if an exclusive lock is held on the database file.
**   It is cleared (set to false) whenever an exclusive lock is
**   relinquished on the database file. Each time a transaction is committed,
**   The changeCountDone flag is inspected. If it is true, the work of
**   updating the change-counter is omitted for the current transaction.
**
**   This mechanism means that when running in exclusive mode, a connection
**   need only update the change-counter once, for the first transaction
**   committed.
**
** setSuper
**
**   When PagerCommitPhaseOne() is called to commit a transaction, it may
**   (or may not) specify a super-journal name to be written into the
**   journal file before it is synced to disk.
**
**   Whether or not a journal file contains a super-journal pointer affects
**   the way in which the journal file is finalized after the transaction is
**   committed or rolled back when running in "journal_mode=PERSIST" mode.
**   If a journal file does not contain a super-journal pointer, it is
**   finalized by overwriting the first journal header with zeroes. If
**   it does contain a super-journal pointer the journal file is finalized
**   by truncating it to zero bytes, just as if the connection were
**   running in "journal_mode=truncate" mode.
**
**   Journal files that contain super-journal pointers cannot be finalized
**   simply by overwriting the first journal-header with zeroes, as the
**   super-journal pointer could interfere with hot-journal rollback of any
**   subsequently interrupted transaction that reuses the journal file.
**
**   The flag is cleared as soon as the journal file is finalized (either
**   by PagerCommitPhaseTwo or PagerRollback). If an IO error prevents the
**   journal file from being successfully finalized, the setSuper flag
**   is cleared anyway (and the pager will move to ERROR state).
**
** doNotSpill
**
**   This variables control the behavior of cache-spills  (calls made by
**   the pcache module to the pagerStress() routine to write cached data
**   to the file-system in order to free up memory).
**
**   When bits SPILLFLAG_OFF or SPILLFLAG_ROLLBACK of doNotSpill are set,
**   writing to the database from pagerStress() is disabled altogether.
**   The SPILLFLAG_ROLLBACK case is done in a very obscure case that
**   comes up during savepoint rollback that requires the pcache module
**   to allocate a new page to prevent the journal file from being written
**   while it is being traversed by code in pager_playback().  The SPILLFLAG_OFF
**   case is a user preference.
**
**   If the SPILLFLAG_NOSYNC bit is set, writing to the database from
**   pagerStress() is permitted, but syncing the journal file is not.
**   This flag is set by sqlite3PagerWrite() when the file-system sector-size
**   is larger than the database page-size in order to prevent a journal sync
**   from happening in between the journalling of two pages on the same sector.
**
** subjInMemory
**
**   This is a boolean variable. If true, then any required sub-journal
**   is opened as an in-memory journal file. If false, then in-memory
**   sub-journals are only used for in-memory pager files.
**
**   This variable is updated by the upper layer each time a new
**   write-transaction is opened.
**
** dbSize, dbOrigSize, dbFileSize
**
**   Variable dbSize is set to the number of pages in the database file.
**   It is valid in PAGER_READER and higher states (all states except for
**   OPEN and ERROR).
**
**   dbSize is set based on the size of the database file, which may be
**   larger than the size of the database (the value stored at offset
**   28 of the database header by the btree). If the size of the file
**   is not an integer multiple of the page-size, the value stored in
**   dbSize is rounded down (i.e. a 5KB file with 2K page-size has dbSize==2).
**   Except, any file that is greater than 0 bytes in size is considered
**   to have at least one page. (i.e. a 1KB file with 2K page-size leads
**   to dbSize==1).
**
**   During a write-transaction, if pages with page-numbers greater than
**   dbSize are modified in the cache, dbSize is updated accordingly.
**   Similarly, if the database is truncated using PagerTruncateImage(),
**   dbSize is updated.
**
**   Variables dbOrigSize and dbFileSize are valid in states
**   PAGER_WRITER_LOCKED and higher. dbOrigSize is a copy of the dbSize
**   variable at the start of the transaction. It is used during rollback,
**   and to determine whether or not pages need to be journalled before
**   being modified.
**
**   Throughout a write-transaction, dbFileSize contains the size of
**   the file on disk in pages. It is set to a copy of dbSize when the
**   write-transaction is first opened, and updated when VFS calls are made
**   to write or truncate the database file on disk.
**
**   The only reason the dbFileSize variable is required is to suppress
**   unnecessary calls to xTruncate() after committing a transaction. If,
**   when a transaction is committed, the dbFileSize variable indicates
**   that the database file is larger than the database image (Pager.dbSize),
**   pager_truncate() is called. The pager_truncate() call uses xFilesize()
**   to measure the database file on disk, and then truncates it if required.
**   dbFileSize is not used when rolling back a transaction. In this case
**   pager_truncate() is called unconditionally (which means there may be
**   a call to xFilesize() that is not strictly required). In either case,
**   pager_truncate() may cause the file to become smaller or larger.
**
** dbHintSize
**
**   The dbHintSize variable is used to limit the number of calls made to
**   the VFS xFileControl(FCNTL_SIZE_HINT) method.
**
**   dbHintSize is set to a copy of the dbSize variable when a
**   write-transaction is opened (at the same time as dbFileSize and
**   dbOrigSize). If the xFileControl(FCNTL_SIZE_HINT) method is called,
**   dbHintSize is increased to the number of pages that correspond to the
**   size-hint passed to the method call. See pager_write_pagelist() for
**   details.
**
** errCode
**
**   The Pager.errCode variable is only ever used in PAGER_ERROR state. It
**   is set to zero in all other states. In PAGER_ERROR state, Pager.errCode
**   is always set to SQLITE_FULL, SQLITE_IOERR or one of the SQLITE_IOERR_XXX
**   sub-codes.
**
** syncFlags, walSyncFlags
**
**   syncFlags is either SQLITE_SYNC_NORMAL (0x02) or SQLITE_SYNC_FULL (0x03).
**   syncFlags is used for rollback mode.  walSyncFlags is used for WAL mode
**   and contains the flags used to sync the checkpoint operations in the
**   lower two bits, and sync flags used for transaction commits in the WAL
**   file in bits 0x04 and 0x08.  In other words, to get the correct sync flags
**   for checkpoint operations, use (walSyncFlags&0x03) and to get the correct
**   sync flags for transaction commit, use ((walSyncFlags>>2)&0x03).  Note
**   that with synchronous=NORMAL in WAL mode, transaction commit is not synced
**   meaning that the 0x04 and 0x08 bits are both zero.

//	** or any other database connection. Exactly how a journal is finalized
//	** depends on whether or not the pager is running in exclusive mode and
//	** the current journal-mode (Pager.journalMode value), as follows:
//	**
//	**   journalMode==MEMORY
//	**     Journal file descriptor is simply closed. This destroys an
//	**     in-memory journal.
//	**
//	**   journalMode==TRUNCATE
//	**     Journal file is truncated to zero bytes in size.
//	**
//	**   journalMode==PERSIST
//	**     The first 28 bytes of the journal file are zeroed. This invalidates
//	**     the first journal header in the file, and hence the entire journal
//	**     file. An invalid journal file cannot be rolled back.
//	**
//	**   journalMode==DELETE
//	**     The journal file is closed and deleted using sqlite3OsDelete().
//	**
//	**     If the pager is running in exclusive mode, this method of finalizing
//	**     the journal file is never used. Instead, if the journalMode is
//	**     DELETE and the pager is in exclusive mode, the method described under
//	**     journalMode==PERSIST is used instead.
//	**
//	** After the journal is finalized, the pager moves to PAGER_READER state.
//	** If running in non-exclusive rollback mode, the lock on the file is
//	** downgraded to a SHARED_LOCK.
//	**
//	** SQLITE_OK is returned if no error occurs. If an error occurs during
//	** any of the IO operations to finalize the journal file or unlock the
//	** database then the IO error code is returned to the user. If the
//	** operation to finalize the journal file fails, then the code still
//	** tries to unlock the database file if not in exclusive mode. If the

//	** to the first error encountered (the journal finalization one) is

//	**
//	** The journal file format is as follows:
//	**
//	**  (1)  8 byte prefix.  A copy of aJournalMagic[].
//	**  (2)  4 byte big-endian integer which is the number of valid page records
//	**       in the journal.  If this value is 0xffffffff, then compute the
//	**       number of page records from the journal size.
//	**  (3)  4 byte big-endian integer which is the initial value for the
//	**       sanity checksum.
//	**  (4)  4 byte integer which is the number of pages to truncate the
//	**       database to during a rollback.
//	**  (5)  4 byte big-endian integer which is the sector size.  The header
//	**       is this many bytes in size.
//	**  (6)  4 byte big-endian integer which is the page size.
//	**  (7)  zero padding out to the next sector size.
//	**  (8)  Zero or more pages instances, each as follows:
//	**        +  4 byte page number.
//	**        +  pPager->pageSize bytes of data.
//	**        +  4 byte checksum
//	**
//	** When we speak of the journal header, we mean the first 7 items above.
//	** Each entry in the journal is an instance of the 8th item.
//	**
//	** Call the value from the second bullet "nRec".  nRec is the number of
//	** valid page entries in the journal.  In most cases, you can compute the
//	** value of nRec from the size of the journal file.  But if a power
//	** failure occurred while the journal was being written, it could be the
//	** case that the size of the journal file had already been increased but
//	** the extra entries had not yet made it safely to disk.  In such a case,
//	** the value of nRec computed from the file size would be too large.  For
//	** that reason, we always use the nRec value in the header.
//	**
//	** If the nRec value is 0xffffffff it means that nRec should be computed
//	** from the file size.  This value is used when the user selects the
//	** no-sync option for the journal.  A power failure could lead to corruption
//	** in this case.  But for things like temporary table (which will be
//	** deleted when the power is restored) we don't care.
//	**
//	** If the file opened as the journal file is not a well-formed
//	** journal file then all pages up to the first corrupted page are rolled
//	** back (or no pages if the journal header is corrupted). The journal file
//	** is then deleted and SQLITE_OK returned, just as if no corruption had
//	** been encountered.
//	**
//	** If an I/O or malloc() error occurs, the journal-file is not deleted
//	** and an error code is returned.
//	**
//	** The isHot parameter indicates that we are trying to rollback a journal
//	** that might be a hot journal.  Or, it could be that the journal is
//	** preserved because of JOURNALMODE_PERSIST or JOURNALMODE_TRUNCATE.

//	** back any content.  If the journal is merely persistent, no reset is

//	**              in a state which would cause damage to the database
//	**              when it is rolled back.
//	**
//	**    FULL      The journal is synced twice before writes begin on the
//	**              database (with some additional information - the nRec field
//	**              of the journal header - being written in between the two
//	**              syncs).  If we assume that writing a
//	**              single disk sector is atomic, then this mode provides
//	**              assurance that the journal will not be corrupted to the
//	**              point of causing damage to the database during rollback.
//	**
//	**    EXTRA     This is like FULL except that is also syncs the directory
//	**              that contains the rollback journal after the rollback
//	**              journal is unlinked.
//	**
//	** The above is for a rollback-journal mode.  For WAL mode, OFF continues
//	** to mean that no syncs ever occur.  NORMAL means that the WAL is synced
//	** prior to the start of checkpoint and that the database file is synced
//	** at the conclusion of the checkpoint if the entire content of the WAL
//	** was written back into the database.  But no sync operations occur for
//	** an ordinary commit in NORMAL mode with WAL.  FULL means that the WAL
//	** file is synced following each commit operation, in addition to the
//	** syncs associated with NORMAL.  There is no difference between FULL
//	** and EXTRA for WAL mode.
//	**
//	** Do not confuse synchronous=FULL with SQLITE_SYNC_FULL.  The
//	** SQLITE_SYNC_FULL macro means to use the MacOSX-style full-fsync
//	** using fcntl(F_FULLFSYNC).  SQLITE_SYNC_NORMAL means to do an
//	** ordinary fsync() call.  There is no difference between SQLITE_SYNC_FULL
//	** and SQLITE_SYNC_NORMAL on platforms other than MacOSX.  But the
//	** synchronous=FULL versus synchronous=NORMAL setting determines when
//	** the xSync primitive is called and is relevant to all platforms.
//	**
//	** Numeric values associated with these states are OFF==1, NORMAL=2,
//	** and FULL=3.

//	** choose not to allocate a new page object and may reuse an existing
//	** object with no outstanding references.
//	**
//	** The extra data appended to a page is always initialized to zeros the
//	** first time a page is loaded into memory. If the page requested is
//	** already in the cache when this function is called, then the extra
//	** data is left as it was when the page object was last used.
//	**
//	** If the database image is smaller than the requested page or if
//	** the flags parameter contains the PAGER_GET_NOCONTENT bit and the
//	** requested page is not already stored in the cache, then no
//	** actual disk read occurs. In this case the memory image of the
//	** page is initialized to all zeros.
//	**
//	** If PAGER_GET_NOCONTENT is true, it means that we do not care about
//	** the contents of the page. This occurs in two scenarios:
//	**
//	**   a) When reading a free-list leaf page from the database, and
//	**
//	**   b) When a savepoint is being rolled back and we need to load
//	**      a new page into the cache to be filled with the data read
//	**      from the savepoint journal.
//	**
//	** If PAGER_GET_NOCONTENT is true, then the data returned is zeroed instead
//	** of being read from the database. Additionally, the bits corresponding
//	** to pgno in Pager.pInJournal (bitvec of pages already written to the
//	** journal file) and the PagerSavepoint.pInSavepoint bitvecs of any open
//	** savepoints are set. This means if the page is made writable at any
//	** point in the future, using a call to sqlite3PagerWrite(), its contents
//	** will not be journaled. This saves IO.
//	**
//	** The acquisition might fail for several reasons.  In all cases,
//	** an appropriate error code is returned and *ppPage is set to NULL.
//	**
//	** See also sqlite3PagerLookup().  Both this routine and Lookup() attempt
//	** to find a page in the in-memory cache first.  If the page is not already
//	** in memory, this routine goes to disk to read it in whereas Lookup()
//	** just returns 0.  This routine acquires a read-lock the first time it

**
** This file contains the implementation of a write-ahead log (WAL) used in
** "journal_mode=WAL" mode.
**
** WRITE-AHEAD LOG (WAL) FILE FORMAT
**
** A WAL file consists of a header followed by zero or more "frames".
** Each frame records the revised content of a single page from the
** database file.  All changes to the database are recorded by writing
** frames into the WAL.  Transactions commit when a frame is written that
** contains a commit marker.  A single WAL can and usually does record
** multiple transactions.  Periodically, the content of the WAL is
** transferred back into the database file in an operation called a
** "checkpoint".
**
** A single WAL file can be used multiple times.  In other words, the
** WAL can fill up with frames and then be checkpointed and then new
** frames can overwrite the old ones.  A WAL always grows from beginning
** toward the end.  Checksums and counters attached to each frame are
** used to determine which frames within the WAL are valid and which
** are leftovers from prior checkpoints.
**
** The WAL header is 32 bytes in size and consists of the following eight
** big-endian 32-bit unsigned integer values:
**
**     0: Magic number.  0x377f0682 or 0x377f0683
**     4: File format version.  Currently 3007000
**     8: Database page size.  Example: 1024
**    12: Checkpoint sequence number
**    16: Salt-1, random integer incremented with each checkpoint
**    20: Salt-2, a different random integer changing with each ckpt
**    24: Checksum-1 (first part of checksum for first 24 bytes of header).
**    28: Checksum-2 (second part of checksum for first 24 bytes of header).
**
** Immediately following the wal-header are zero or more frames. Each
** frame consists of a 24-byte frame-header followed by a <page-size> bytes
** of page data. The frame-header is six big-endian 32-bit unsigned
** integer values, as follows:
**
**     0: Page number.
**     4: For commit records, the size of the database image in pages
**        after the commit. For all other records, zero.
**     8: Salt-1 (copied from the header)
**    12: Salt-2 (copied from the header)
**    16: Checksum-1.
**    20: Checksum-2.
**
** A frame is considered valid if and only if the following conditions are
** true:
**
**    (1) The salt-1 and salt-2 values in the frame-header match
**        salt values in the wal-header
**
**    (2) The checksum values in the final 8 bytes of the frame-header
**        exactly match the checksum computed consecutively on the
**        WAL header and the first 8 bytes and the content of all frames
**        up to and including the current frame.
**
** The checksum is computed using 32-bit big-endian integers if the
** magic number in the first 4 bytes of the WAL is 0x377f0683 and it
** is computed using little-endian if the magic number is 0x377f0682.
** The checksum values are always stored in the frame header in a
** big-endian format regardless of which byte order is used to compute
** the checksum.  The checksum is computed by interpreting the input as
** an even number of unsigned 32-bit integers: x[0] through x[N].  The
** algorithm used for the checksum is as follows:
**
**   for i from 0 to n-1 step 2:
**     s0 += x[i] + s1;
**     s1 += x[i+1] + s0;
**   endfor
**
** Note that s0 and s1 are both weighted checksums using fibonacci weights
** in reverse order (the largest fibonacci weight occurs on the first element
** of the sequence being summed.)  The s1 value spans all 32-bit
** terms of the sequence whereas s0 omits the final term.
**
** On a checkpoint, the WAL is first VFS.xSync-ed, then valid content of the
** WAL is transferred into the database, then the database is VFS.xSync-ed.
** The VFS.xSync operations serve as write barriers - all writes launched
** before the xSync must complete before any write that launches after the
** xSync begins.
**
** After each checkpoint, the salt-1 value is incremented and the salt-2
** value is randomized.  This prevents old and new frames in the WAL from
** being considered valid at the same time and being checkpointing together
** following a crash.
**
** READER ALGORITHM
**
** To read a page from the database (call it page number P), a reader
** first checks the WAL to see if it contains page P.  If so, then the
** last valid instance of page P that is a followed by a commit frame
** or is a commit frame itself becomes the value read.  If the WAL
** contains no copies of page P that are valid and which are a commit
** frame or are followed by a commit frame, then page P is read from
** the database file.
**
** To start a read transaction, the reader records the index of the last
** valid frame in the WAL.  The reader uses this recorded "mxFrame" value
** for all subsequent read operations.  New transactions can be appended
** to the WAL, but as long as the reader uses its original mxFrame value
** and ignores the newly appended content, it will see a consistent snapshot
** of the database from a single point in time.  This technique allows
** multiple concurrent readers to view different versions of the database
** content simultaneously.
**
** The reader algorithm in the previous paragraphs works correctly, but
** because frames for page P can appear anywhere within the WAL, the
** reader has to scan the entire WAL looking for page P frames.  If the
** WAL is large (multiple megabytes is typical) that scan can be slow,
** and read performance suffers.  To overcome this problem, a separate
** data structure called the wal-index is maintained to expedite the
** search for frames of a particular page.
**
** WAL-INDEX FORMAT
**
** Conceptually, the wal-index is shared memory, though VFS implementations
** might choose to implement the wal-index using a mmapped file.  Because
** the wal-index is shared memory, SQLite does not support journal_mode=WAL
** on a network filesystem.  All users of the database must be able to
** share memory.
**
** In the default unix and windows implementation, the wal-index is a mmapped
** file whose name is the database name with a "-shm" suffix added.  For that
** reason, the wal-index is sometimes called the "shm" file.
**
** The wal-index is transient.  After a crash, the wal-index can (and should
** be) reconstructed from the original WAL file.  In fact, the VFS is required
** to either truncate or zero the header of the wal-index when the last
** connection to it closes.  Because the wal-index is transient, it can
** use an architecture-specific format; it does not have to be cross-platform.
** Hence, unlike the database and WAL file formats which store all values
** as big endian, the wal-index can store multi-byte values in the native
** byte order of the host computer.
**
** The purpose of the wal-index is to answer this question quickly:  Given
** a page number P and a maximum frame index M, return the index of the
** last frame in the wal before frame M for page P in the WAL, or return
** NULL if there are no frames for page P in the WAL prior to M.
**
** The wal-index consists of a header region, followed by an one or
** more index blocks.
**
** The wal-index header contains the total number of frames within the WAL
** in the mxFrame field.
**
** Each index block except for the first contains information on
** HASHTABLE_NPAGE frames. The first index block contains information on
** HASHTABLE_NPAGE_ONE frames. The values of HASHTABLE_NPAGE_ONE and
** HASHTABLE_NPAGE are selected so that together the wal-index header and
** first index block are the same size as all other index blocks in the
** wal-index.  The values are:
**
**   HASHTABLE_NPAGE      4096
**   HASHTABLE_NPAGE_ONE  4062
**
** Each index block contains two sections, a page-mapping that contains the
** database page number associated with each wal frame, and a hash-table
** that allows readers to query an index block for a specific page number.
** The page-mapping is an array of HASHTABLE_NPAGE (or HASHTABLE_NPAGE_ONE
** for the first index block) 32-bit page numbers. The first entry in the
** first index-block contains the database page number corresponding to the
** first frame in the WAL file. The first entry in the second index block
** in the WAL file corresponds to the (HASHTABLE_NPAGE_ONE+1)th frame in
** the log, and so on.
**
** The last index block in a wal-index usually contains less than the full
** complement of HASHTABLE_NPAGE (or HASHTABLE_NPAGE_ONE) page-numbers,
** depending on the contents of the WAL file. This does not change the
** allocated size of the page-mapping array - the page-mapping array merely
** contains unused entries.
**
** Even without using the hash table, the last frame for page P
** can be found by scanning the page-mapping sections of each index block
** starting with the last index block and moving toward the first, and
** within each index block, starting at the end and moving toward the
** beginning.  The first entry that equals P corresponds to the frame
** holding the content for that page.
**
** The hash table consists of HASHTABLE_NSLOT 16-bit unsigned integers.
** HASHTABLE_NSLOT = 2*HASHTABLE_NPAGE, and there is one entry in the
** hash table for each page number in the mapping section, so the hash
** table is never more than half full.  The expected number of collisions
** prior to finding a match is 1.  Each entry of the hash table is an
** 1-based index of an entry in the mapping section of the same
** index block.   Let K be the 1-based index of the largest entry in
** the mapping section.  (For index blocks other than the last, K will
** always be exactly HASHTABLE_NPAGE (4096) and for the last index block
** K will be (mxFrame%HASHTABLE_NPAGE).)  Unused slots of the hash table
** contain a value of 0.
**
** To look for page P in the hash table, first compute a hash iKey on
** P as follows:
**
**      iKey = (P * 383) % HASHTABLE_NSLOT
**
** Then start scanning entries of the hash table, starting with iKey
** (wrapping around to the beginning when the end of the hash table is
** reached) until an unused hash slot is found. Let the first unused slot
** be at index iUnused.  (iUnused might be less than iKey if there was
** wrap-around.) Because the hash table is never more than half full,
** the search is guaranteed to eventually hit an unused entry.  Let
** iMax be the value between iKey and iUnused, closest to iUnused,
** where aHash[iMax]==P.  If there is no iMax entry (if there exists
** no hash slot such that aHash[i]==p) then page P is not in the
** current index block.  Otherwise the iMax-th mapping entry of the
** current index block corresponds to the last entry that references
** page P.
**
** A hash search begins with the last index block and moves toward the
** first index block, looking for entries corresponding to page P.  On
** average, only two or three slots in each index block need to be
** examined in order to either find the last entry for page P, or to
** establish that no such entry exists in the block.  Each index block
** holds over 4000 entries.  So two or three index blocks are sufficient
** to cover a typical 10 megabyte WAL file, assuming 1K pages.  8 or 10
** comparisons (on average) suffice to either locate a frame in the
** WAL or to establish that the frame does not exist in the WAL.  This
** is much faster than scanning the entire 10MB WAL.
**
** Note that entries are added in order of increasing K.  Hence, one
** reader might be using some value K0 and a second reader that started
** at a later time (after additional transactions were added to the WAL
** and to the wal-index) might be using a different value K1, where K1>K0.
** Both readers can use the same hash table and mapping section to get
** the correct result.  There may be entries in the hash table with
** K>K0 but to the first reader, those entries will appear to be unused
** slots in the hash table and so the first reader will get an answer as
** if no values greater than K0 had ever been inserted into the hash table
** in the first place - which is what reader one wants.  Meanwhile, the
** second reader using K1 will see additional values that were inserted
** later, which is exactly what reader two wants.
**
** When a rollback occurs, the value of K is decreased. Hash table entries
** that correspond to frames greater than the new K value are removed
** from the hash table at this point.

** the mxFrame for that reader.  The value READMARK_NOT_USED (0xffffffff)
** for any aReadMark[] means that entry is unused.  aReadMark[0] is
** a special case; its value is never used and it exists as a place-holder
** to avoid having to offset aReadMark[] indexes by one.  Readers holding
** WAL_READ_LOCK(0) always ignore the entire WAL and read all content
** directly from the database.
**
** The value of aReadMark[K] may only be changed by a thread that
** is holding an exclusive lock on WAL_READ_LOCK(K).  Thus, the value of
** aReadMark[K] cannot changed while there is a reader is using that mark
** since the reader will be holding a shared lock on WAL_READ_LOCK(K).
**
** The checkpointer may only transfer frames from WAL to database where
** the frame numbers are less than or equal to every aReadMark[] that is
** in use (that is, every aReadMark[j] for which there is a corresponding
** WAL_READ_LOCK(j)).  New readers (usually) pick the aReadMark[] with the
** largest value and will increase an unused aReadMark[] to mxFrame if there
** is not already an aReadMark[] equal to mxFrame.  The exception to the
** previous sentence is when nBackfill equals mxFrame (meaning that everything
** in the WAL has been backfilled into the database) then new readers
** will choose aReadMark[0] which has value 0 and hence such reader will
** get all their all content directly from the database file and ignore
** the WAL.
**
** Writers normally append new frames to the end of the WAL.  However,
** if nBackfill equals mxFrame (meaning that all WAL content has been
** written back into the database) and if no readers are using the WAL
** (in other words, if there are no WAL_READ_LOCK(i) where i>0) then
** the writer will first "reset" the WAL back to the beginning and start
** writing new content beginning at frame 1.
**
** We assume that 32-bit loads are atomic and so no locks are needed in
** order to read from any aReadMark[] entries.

	 ** that the log file may have been wrapped by a writer, or that frames

	 **
	 ** Before checking that the live wal-index header has not changed

	 ** file that has not yet been checkpointed. This client will not need
	 ** to read any frames earlier than minFrame from the wal file - they

	 ** a version of page X that lies before pWal->minFrame (call that version
	 ** A) on the basis that there is a newer version (version B) of the same
	 ** page later in the wal file. But if version B happens to like past
	 ** frame pWal->hdr.mxFrame - then the client would incorrectly assume
	 ** that it can read version A from the database file. However, since

**
*************************************************************************
** This file implements an external (disk-based) database using BTrees.
** For a detailed discussion of BTrees, refer to
**
**     Donald E. Knuth, THE ART OF COMPUTER PROGRAMMING, Volume 3:
**     "Sorting And Searching", pages 473-480. Addison-Wesley
**     Publishing Company, Reading, Massachusetts.
**
** The basic idea is that each page of the file contains N database
** entries and N+1 pointers to subpages.
**
**   ----------------------------------------------------------------
**   |  Ptr(0) | Key(0) | Ptr(1) | Key(1) | ... | Key(N-1) | Ptr(N) |
**   ----------------------------------------------------------------
**
** All of the keys on the page that Ptr(0) points to have values less
** than Key(0).  All of the keys on page Ptr(1) and its subpages have
** values greater than Key(0) and less than Key(1).  All of the keys
** on Ptr(N) and its subpages have values greater than Key(N-1).  And
** so forth.
**
** Finding a particular key requires reading O(log(M)) pages from the
** disk where M is the number of entries in the tree.
**
** In this implementation, a single file can hold one or more separate
** BTrees.  Each BTree is identified by the index of its root page.  The
** key and data for any entry are combined to form the "payload".  A
** fixed amount of payload can be carried directly on the database
** page.  If the payload is larger than the preset amount then surplus
** bytes are stored on overflow pages.  The payload for an entry
** and the preceding pointer are combined to form a "Cell".  Each
** page has a small header which contains the Ptr(N) pointer and other
** information such as the size of key and data.
**
** FORMAT DETAILS
**
** The file is divided into pages.  The first page is called page 1,
** the second is page 2, and so forth.  A page number of zero indicates
** "no such page".  The page size can be any power of 2 between 512 and 65536.
** Each page can be either a btree page, a freelist page, an overflow
** page, or a pointer-map page.
**
** The first page is always a btree page.  The first 100 bytes of the first
** page contain a special header (the "file header") that describes the file.
** The format of the file header is as follows:
**
**   OFFSET   SIZE    DESCRIPTION
**      0      16     Header string: "SQLite format 3\000"
**     16       2     Page size in bytes.  (1 means 65536)
**     18       1     File format write version
**     19       1     File format read version
**     20       1     Bytes of unused space at the end of each page
**     21       1     Max embedded payload fraction (must be 64)
**     22       1     Min embedded payload fraction (must be 32)
**     23       1     Min leaf payload fraction (must be 32)
**     24       4     File change counter
**     28       4     The size of the database in pages
**     32       4     First freelist page
**     36       4     Number of freelist pages in the file
**     40      60     15 4-byte meta values passed to higher layers
**
**     40       4     Schema cookie
**     44       4     File format of schema layer
**     48       4     Size of page cache
**     52       4     Largest root-page (auto/incr_vacuum)
**     56       4     1=UTF-8 2=UTF16le 3=UTF16be
**     60       4     User version
**     64       4     Incremental vacuum mode
**     68       4     Application-ID
**     72      20     unused
**     92       4     The version-valid-for number
**     96       4     SQLITE_VERSION_NUMBER
**
** All of the integer values are big-endian (most significant byte first).
**
** The file change counter is incremented when the database is changed
** This counter allows other processes to know when the file has changed
** and thus when they need to flush their cache.
**
** The max embedded payload fraction is the amount of the total usable
** space in a page that can be consumed by a single cell for standard
** B-tree (non-LEAFDATA) tables.  A value of 255 means 100%.  The default
** is to limit the maximum cell size so that at least 4 cells will fit
** on one page.  Thus the default max embedded payload fraction is 64.
**
** If the payload for a cell is larger than the max payload, then extra
** payload is spilled to overflow pages.  Once an overflow page is allocated,
** as many bytes as possible are moved into the overflow pages without letting
** the cell size drop below the min embedded payload fraction.
**
** The min leaf payload fraction is like the min embedded payload fraction
** except that it applies to leaf nodes in a LEAFDATA tree.  The maximum
** payload fraction for a LEAFDATA tree is always 100% (or 255) and it
** not specified in the header.

** Each btree pages is divided into three sections:  The header, the
** cell pointer array, and the cell content area.  Page 1 also has a 100-byte
** file header that occurs before the page header.
**
**      |----------------|
**      | file header    |   100 bytes.  Page 1 only.
**      |----------------|
**      | page header    |   8 bytes for leaves.  12 bytes for interior nodes
**      |----------------|
**      | cell pointer   |   |  2 bytes per cell.  Sorted order.
**      | array          |   |  Grows downward
**      |                |   v
**      |----------------|
**      | unallocated    |
**      | space          |
**      |----------------|   ^  Grows upwards
**      | cell content   |   |  Arbitrary order interspersed with freeblocks.
**      | area           |   |  and free space fragments.
**      |----------------|
**
** The page headers looks like this:
**
**   OFFSET   SIZE     DESCRIPTION
**      0       1      Flags. 1: intkey, 2: zerodata, 4: leafdata, 8: leaf
**      1       2      byte offset to the first freeblock
**      3       2      number of cells on this page
**      5       2      first byte of the cell content area
**      7       1      number of fragmented free bytes
**      8       4      Right child (the Ptr(N) value).  Omitted on leaves.
**
** The flags define the format of this btree page.  The leaf flag means that
** this page has no children.  The zerodata flag means that this page carries
** only keys and no data.  The intkey flag means that the key is an integer
** which is stored in the key size entry of the cell header rather than in
** the payload area.
**
** The cell pointer array begins on the first byte after the page header.
** The cell pointer array contains zero or more 2-byte numbers which are
** offsets from the beginning of the page to the cell content in the cell
** content area.  The cell pointers occur in sorted order.  The system strives
** to keep free space after the last cell pointer so that new cells can
** be easily added without having to defragment the page.
**
** Cell content is stored at the very end of the page and grows toward the
** beginning of the page.
**
** Unused space within the cell content area is collected into a linked list of
** freeblocks.  Each freeblock is at least 4 bytes in size.  The byte offset
** to the first freeblock is given in the header.  Freeblocks occur in
** increasing order.  Because a freeblock must be at least 4 bytes in size,
** any group of 3 or fewer unused bytes in the cell content area cannot
** exist on the freeblock chain.  A group of 3 or fewer free bytes is called
** a fragment.  The total number of bytes in all fragments is recorded.
** in the page header at offset 7.
**
**    SIZE    DESCRIPTION
**      2     Byte offset of the next freeblock
**      2     Bytes in this freeblock
**
** Cells are of variable length.  Cells are stored in the cell content area at
** the end of the page.  Pointers to the cells are in the cell pointer array
** that immediately follows the page header.  Cells is not necessarily
** contiguous or in order, but cell pointers are contiguous and in order.
**
** Cell content makes use of variable length integers.  A variable
** length integer is 1 to 9 bytes where the lower 7 bits of each
** byte are used.  The integer consists of all bytes that have bit 8 set and
** the first byte with bit 8 clear.  The most significant byte of the integer
** appears first.  A variable-length integer may not be more than 9 bytes long.
** As a special case, all 8 bits of the 9th byte are used as data.  This
** allows a 64-bit integer to be encoded in 9 bytes.
**
**    0x00                      becomes  0x00000000
**    0x7f                      becomes  0x0000007f
**    0x81 0x00                 becomes  0x00000080
**    0x82 0x00                 becomes  0x00000100
**    0x80 0x7f                 becomes  0x0000007f
**    0x81 0x91 0xd1 0xac 0x78  becomes  0x12345678
**    0x81 0x81 0x81 0x81 0x01  becomes  0x10204081
**
** Variable length integers are used for rowids and to hold the number of
** bytes of key and data in a btree cell.
**
** The content of a cell looks like this:
**
**    SIZE    DESCRIPTION
**      4     Page number of the left child. Omitted if leaf flag is set.
**     var    Number of bytes of data. Omitted if the zerodata flag is set.
**     var    Number of bytes of key. Or the key itself if intkey flag is set.
**      *     Payload
**      4     First page of the overflow chain.  Omitted if no overflow
**
** Overflow pages form a linked list.  Each page except the last is completely
** filled with data (pagesize - 4 bytes).  The last page can have as little
** as 1 byte of data.
**
**    SIZE    DESCRIPTION
**      4     Page number of next overflow page
**      *     Data
**
** Freelist pages come in two subtypes: trunk pages and leaf pages.  The
** file header points to the first in a linked list of trunk page.  Each trunk
** page points to multiple leaf pages.  The content of a leaf page is
** unspecified.  A trunk page looks like this:
**
**    SIZE    DESCRIPTION
**      4     Page number of next trunk page
**      4     Number of leaf pointers on this page
**      *     zero or more pages numbers of leaves

//	** Set bit pgno of the BtShared.pHasContent bitvec. This is called

//	**
//	** The BtShared.pHasContent bitvec exists to work around an obscure
//	** bug caused by the interaction of two useful IO optimizations surrounding
//	** free-list leaf pages:
//	**
//	**   1) When all data is deleted from a page and the page becomes
//	**      a free-list leaf page, the page is not written to the database
//	**      (as free-list leaf pages contain no meaningful data). Sometimes
//	**      such a page is not even journalled (as it will not be modified,
//	**      why bother journalling it?).
//	**
//	**   2) When a free-list leaf page is reused, its content is not read
//	**      from the database or written to the journal file (why should it
//	**      be, if it is not at all meaningful?).
//	**
//	** By themselves, these optimizations work fine and provide a handy
//	** performance boost to bulk delete or insert operations. However, if
//	** a page is moved to the free-list and then reused within the same
//	** transaction, a problem comes up. If the page is not journalled when
//	** it is moved to the free-list and it is also not journalled when it
//	** is extracted from the free-list and reused, then the original data
//	** may be lost. In the event of a rollback, it may not be possible
//	** to restore the database to its original configuration.
//	**
//	** The solution is the BtShared.pHasContent bitvec. Whenever a page is
//	** moved to become a free-list leaf page, the corresponding bit is
//	** set in the bitvec. Whenever a leaf page is extracted from the free-list,
//	** optimization 2 above is omitted if the corresponding bit is already

//	**
//	** If the BTREE_WRCSR bit of wrFlag is clear, then the cursor can only

//	** for writing to be allowed:
//	**
//	** 1:  The cursor must have been opened with wrFlag containing BTREE_WRCSR
//	**
//	** 2:  Other database connections that share the same pager cache
//	**     but which are not in the READ_UNCOMMITTED state may not have
//	**     cursors open with wrFlag==0 on the same table.  Otherwise
//	**     the changes made by this write cursor would be visible to
//	**     the read cursors in the other database connection.
//	**
//	** 3:  The database must be writable (not on read-only media)
//	**
//	** 4:  There must be an active transaction.
//	**
//	** The BTREE_FORDELETE bit of wrFlag may optionally be set if BTREE_WRCSR

//	** rows are deleted, the FORDELETE flag is a hint that all SEEK and DELETE
//	** operations on this cursor can be no-ops and all READ operations can
//	** return a null row (2-bytes: 0x01 0x00).

//	** A CellArray object contains a cache of pointers and sizes for a
//	** consecutive sequence of cells that might be held on multiple pages.
//	**
//	** The cells in this array are the divider cell or cells from the pParent
//	** page plus up to three child pages.  There are a total of nCell cells.
//	**
//	** pRef is a pointer to one of the pages that contributes cells.  This is
//	** used to access information such as MemPage.intKey and MemPage.pBt->pageSize
//	** which should be common to all pages that contribute cells to this array.
//	**
//	** apCell[] and szCell[] hold, respectively, pointers to the start of each
//	** cell and the size of each cell.  Some of the apCell[] pointers might refer
//	** to overflow cells.  In other words, some apCel[] pointers might not point
//	** to content area of the pages.
//	**
//	** A szCell[] of zero means the size of that cell has not yet been computed.
//	**
//	** The cells come from as many as four different pages:
//	**
//	**             -----------
//	**             | Parent  |
//	**             -----------
//	**            /     |     **           /      |      **  ---------   ---------   ---------
//	**  |Child-1|   |Child-2|   |Child-3|
//	**  ---------   ---------   ---------
//	**
//	** The order of cells is in the array is for an index btree is:
//	**
//	**       1.  All cells from Child-1 in order
//	**       2.  The first divider cell from Parent
//	**       3.  All cells from Child-2 in order
//	**       4.  The second divider cell from Parent
//	**       5.  All cells from Child-3 in order
//	**
//	** For a table-btree (with rowids) the items 2 and 4 are empty because
//	** content exists only in leaves and there are no divider cells.
//	**
//	** For an index btree, the apEnd[] array holds pointer to the end of page
//	** for Child-1, the Parent, Child-2, the Parent (again), and Child-3,
//	** respectively. The ixNx[] array holds the number of cells contained in
//	** each of these 5 stages, and all stages to the left.  Hence:
//	**
//	**    ixNx[0] = Number of cells in Child-1.
//	**    ixNx[1] = Number of cells in Child-1 plus 1 for first divider.
//	**    ixNx[2] = Number of cells in Child-1 and Child-2 + 1 for 1st divider.
//	**    ixNx[3] = Number of cells in Child-1 and Child-2 + both divider cells
//	**    ixNx[4] = Total number of cells.
//	**
//	** For a table-btree, the concept is similar, except only apEnd[0]..apEnd[2]
//	** are used and they point to the leaf pages only, and the ixNx value are:
//	**
//	**    ixNx[0] = Number of cells in Child-1.
//	**    ixNx[1] = Number of cells in Child-1 and Child-2.
//	**    ixNx[2] = Total number of cells.
//	**
//	** Sometimes when deleting, a child page can have zero cells.  In those
//	** cases, ixNx[] entries with higher indexes, and the corresponding apEnd[]
//	** entries, shift down.  The end result is that each ixNx[] entry should
//	** be larger than the previous

//	** This routine redistributes cells on the iParentIdx'th child of pParent
//	** (hereafter "the page") and up to 2 siblings so that all pages have about the
//	** same amount of free space. Usually a single sibling on either side of the
//	** page are used in the balancing, though both siblings might come from one
//	** side if the page is the first or last child of its parent. If the page
//	** has fewer than 2 siblings (something which can only happen if the page
//	** is a root page or a child of a root page) then all available siblings
//	** participate in the balancing.
//	**
//	** The number of siblings of the page might be increased or decreased by
//	** one or two in an effort to keep pages nearly full but not over full.
//	**
//	** Note that when this routine is called, some of the cells on the page
//	** might not actually be stored in MemPage.aData[]. This can happen
//	** if the page is overfull. This routine ensures that all cells allocated
//	** to the page and its siblings fit into MemPage.aData[] before returning.
//	**
//	** In the course of balancing the page and its siblings, cells may be
//	** inserted into or removed from the parent page (pParent). Doing so
//	** may cause the parent page to become overfull or underfull. If this
//	** happens, it is the responsibility of the caller to invoke the correct
//	** balancing routine to fix this problem (see the balance() routine).
//	**
//	** If this routine fails for any reason, it might leave the database
//	** in a corrupted state. So if this routine fails, the database should
//	** be rolled back.
//	**
//	** The third argument to this function, aOvflSpace, is a pointer to a
//	** buffer big enough to hold one page. If while inserting cells into the parent
//	** page (pParent) the parent page becomes overfull, this buffer is
//	** used to store the parent's overflow cells. Because this function inserts
//	** a maximum of four divider cells into the parent page, and the maximum
//	** size of a cell stored within an internal node is always less than 1/4
//	** of the page-size, the aOvflSpace[] buffer is guaranteed to be large
//	** enough for all overflow cells.
//	**
//	** If aOvflSpace is set to a null pointer, this function returns
//	** SQLITE_NOMEM.

** THREAD SAFETY NOTES:
**
**   Once it has been created using backup_init(), a single sqlite3_backup
**   structure may be accessed via two groups of thread-safe entry points:
**
**     * Via the sqlite3_backup_XXX() API function backup_step() and
**       backup_finish(). Both these functions obtain the source database
**       handle mutex and the mutex associated with the source BtShared
**       structure, in that order.
**
**     * Via the BackupUpdate() and BackupRestart() functions, which are
**       invoked by the pager layer to report various state changes in
**       the page cache associated with the source database. The mutex
**       associated with the source database BtShared structure will always
**       be held when either of these functions are invoked.
**
**   The other sqlite3_backup_XXX() API functions, backup_remaining() and
**   backup_pagecount() are not thread-safe functions. If they are called
**   while some other thread is calling backup_step() or backup_finish(),
**   the values returned may be invalid. There is no way for a call to
**   BackupUpdate() or BackupRestart() to interfere with backup_remaining()
**   or backup_pagecount().
**
**   Depending on the SQLite configuration, the database handles and/or
**   the Btree objects may have their own mutexes that require locking.
**   Non-sharable Btrees (in-memory databases for example), do not have
**   associated mutexes.

**
** (later):  It is reported to me that the mixed-endian problem
** on ARM7 is an issue with GCC, not with the ARM7 chip.  It seems
** that early versions of GCC stored the two words of a 64-bit
** float in the wrong order.  And that error has been propagated
** ever since.  The blame is not necessarily with GCC, though.
** GCC might have just copying the problem from a prior compiler.
** I am also told that newer versions of GCC that follow a different
** ABI get the byte order right.
**
** Developers using SQLite on an ARM7 should compile and run their
** application using -DSQLITE_DEBUG=1 at least once.  With DEBUG
** enabled, some asserts below will ensure that the byte order of
** floating point values is correct.
**
** (2007-08-30)  Frank van Vugt has studied this problem closely
** and has send his findings to the SQLite developers.  Frank
** writes that some Linux kernels offer floating point hardware
** emulation that uses only 32-bit mantissas instead of a full
** 48-bits as required by the IEEE standard.  (This is the
** CONFIG_FPE_FASTFPE option.)  On such systems, floating point
** byte swapping becomes very complicated.  To avoid problems,
** the necessary byte swapping is carried out using a 64-bit integer
** rather than a 64-bit float.  Frank assures us that the code here
** works for him.  We, the developers, have no way to independently
** verify this, but Frank seems to know what he is talking about

** M is the type of branch.  I is the direction taken for this instance of

**
**   M: 2 - two-way branch (I=0: fall-thru   1: jump                )
**      3 - two-way + NULL (I=0: fall-thru   1: jump      2: NULL   )
**      4 - OP_Jump        (I=0: jump p1     1: jump p2   2: jump p3)
**
** In other words, if M is 2, then I is either 0 (for fall-through) or
** 1 (for when the branch is taken).  If M is 3, the I is 0 for an
** ordinary fall-through, I is 1 if the branch was taken, and I is 2
** if the result of comparison is NULL.  For M=3, I=2 the jump may or
** may not be taken, depending on the SQLITE_JUMPIFNULL flags in p5.
** When M is 4, that means that an OP_Jump is being run.  I is 0, 1, or 2
** depending on if the operands are less than, equal, or greater than.
**
** iSrcLine is the source code line (from the __LINE__ macro) that
** generated the VDBE instruction combined with flag bits.  The source
** code line number is in the lower 24 bits of iSrcLine and the upper
** 8 bytes are flags.  The lower three bits of the flags indicate
** values for I that should never occur.  For example, if the branch is
** always taken, the flags should be 0x05 since the fall-through and
** alternate branch are never taken.  If a branch is never taken then
** flags should be 0x06 since only the fall-through approach is allowed.
**
** Bit 0x08 of the flags indicates an OP_Jump opcode that is only
** interested in equal or not-equal.  In other words, I==0 and I==2
** should be treated as equivalent
**
** Since only a line number is retained, not the filename, this macro
** only works for amalgamation builds.  But that is ok, since these macros
** should be no-ops except for special builds used to measure test coverage.

		 ** What follows is a massive switch statement where each case implements a
		 ** separate instruction in the virtual machine.  If we follow the usual
		 ** indentation conventions, each case should be indented by 6 spaces.  But
		 ** that is a lot of wasted space on the left margin.  So the code within
		 ** the switch statement will break with convention and be flush-left. Another
		 ** big comment (similar to this one) will mark the point in the code where
		 ** we transition back to normal indentation.
		 **
		 ** The formatting of each case is important.  The makefile for SQLite
		 ** generates two C files "opcodes.h" and "opcodes.c" by scanning this
		 ** file looking for lines that begin with "case OP_".  The opcodes.h files
		 ** will be filled with #defines that give unique integer values to each
		 ** opcode and the opcodes.c file is filled with an array of strings where
		 ** each string is the symbolic name for the corresponding opcode.  If the
		 ** case statement is followed by a comment of the form "/# same as ... #/"
		 ** that comment is used to determine the particular value of the opcode.
		 **
		 ** Other keywords in the comment that follows each case are used to
		 ** construct the OPFLG_INITIALIZER value that initializes opcodeProperty[].
		 ** Keywords include: in1, in2, in3, out2, out3.  See
		 ** the mkopcodeh.awk script for additional information.
		 **
		 ** Documentation about VDBE opcodes is generated by scanning this file
		 ** for lines of that contain "Opcode:".  That line and all subsequent
		 ** comment lines are used in the generation of the opcode.html documentation
		 ** file.

		 ** Synopsis: Scan-ahead up to P1 rows
		 **
		 ** This opcode is a prefix opcode to OP_SeekGE.  In other words, this
		 ** opcode must be immediately followed by OP_SeekGE. This constraint is
		 ** checked by assert() statements.
		 **
		 ** This opcode uses the P1 through P4 operands of the subsequent
		 ** OP_SeekGE.  In the text that follows, the operands of the subsequent
		 ** OP_SeekGE opcode are denoted as SeekOP.P1 through SeekOP.P4.   Only
		 ** the P1, P2 and P5 operands of this opcode are also used, and  are called
		 ** This.P1, This.P2 and This.P5.
		 **
		 ** This opcode helps to optimize IN operators on a multi-column index
		 ** where the IN operator is on the later terms of the index by avoiding
		 ** unnecessary seeks on the btree, substituting steps to the next row
		 ** of the b-tree instead.  A correct answer is obtained if this opcode
		 ** is omitted or is a no-op.
		 **
		 ** The SeekGE.P3 and SeekGE.P4 operands identify an unpacked key which
		 ** is the desired entry that we want the cursor SeekGE.P1 to be pointing
		 ** to.  Call this SeekGE.P3/P4 row the "target".
		 **
		 ** If the SeekGE.P1 cursor is not currently pointing to a valid row,
		 ** then this opcode is a no-op and control passes through into the OP_SeekGE.
		 **
		 ** If the SeekGE.P1 cursor is pointing to a valid row, then that row
		 ** might be the target row, or it might be near and slightly before the
		 ** target row, or it might be after the target row.  If the cursor is
		 ** currently before the target row, then this opcode attempts to position
		 ** the cursor on or after the target row by invoking sqlite3BtreeStep()
		 ** on the cursor between 1 and This.P1 times.
		 **
		 ** The This.P5 parameter is a flag that indicates what to do if the
		 ** cursor ends up pointing at a valid row that is past the target
		 ** row.  If This.P5 is false (0) then a jump is made to SeekGE.P2.  If
		 ** This.P5 is true (non-zero) then a jump is made to This.P2.  The P5==0
		 ** case occurs when there are no inequality constraints to the right of
		 ** the IN constraint.  The jump to SeekGE.P2 ends the loop.  The P5!=0 case
		 ** occurs when there are inequality constraints to the right of the IN
		 ** operator.  In that case, the This.P2 will point either directly to or
		 ** to setup code prior to the OP_IdxGT or OP_IdxGE opcode that checks for
		 ** loop terminate.
		 **
		 ** Possible outcomes from this opcode:<ol>
		 **
		 ** <li> If the cursor is initially not pointed to any valid row, then
		 **      fall through into the subsequent OP_SeekGE opcode.
		 **
		 ** <li> If the cursor is left pointing to a row that is before the target
		 **      row, even after making as many as This.P1 calls to
		 **      sqlite3BtreeNext(), then also fall through into OP_SeekGE.
		 **
		 ** <li> If the cursor is left pointing at the target row, either because it
		 **      was at the target row to begin with or because one or more
		 **      sqlite3BtreeNext() calls moved the cursor to the target row,
		 **      then jump to This.P2..,
		 **
		 ** <li> If the cursor started out before the target row and a call to
		 **      to sqlite3BtreeNext() moved the cursor off the end of the index
		 **      (indicating that the target row definitely does not exist in the
		 **      btree) then jump to SeekGE.P2, ending the loop.
		 **
		 ** <li> If the cursor ends up on a valid row that is past the target row
		 **      (indicating that the target row does not exist in the btree) then
		 **      jump to SeekOP.P2 if This.P5==0 or to This.P2 if This.P5>0.

** This file contains code for the VdbeSorter object, used in concert with
** a VdbeCursor to sort large numbers of keys for CREATE INDEX statements
** or by SELECT statements with ORDER BY clauses that cannot be satisfied
** using indexes and without LIMIT clauses.
**
** The VdbeSorter object implements a multi-threaded external merge sort
** algorithm that is efficient even if the number of elements being sorted
** exceeds the available memory.
**
** Here is the (internal, non-API) interface between this module and the
** rest of the SQLite system:
**
**    sqlite3VdbeSorterInit()       Create a new VdbeSorter object.
**
**    sqlite3VdbeSorterWrite()      Add a single new row to the VdbeSorter
**                                  object.  The row is a binary blob in the
**                                  OP_MakeRecord format that contains both
**                                  the ORDER BY key columns and result columns
**                                  in the case of a SELECT w/ ORDER BY, or
**                                  the complete record for an index entry
**                                  in the case of a CREATE INDEX.
**
**    sqlite3VdbeSorterRewind()     Sort all content previously added.
**                                  Position the read cursor on the
**                                  first sorted element.
**
**    sqlite3VdbeSorterNext()       Advance the read cursor to the next sorted
**                                  element.
**
**    sqlite3VdbeSorterRowkey()     Return the complete binary blob for the
**                                  row currently under the read cursor.
**
**    sqlite3VdbeSorterCompare()    Compare the binary blob for the row
**                                  currently under the read cursor against
**                                  another binary blob X and report if
**                                  X is strictly less than the read cursor.
**                                  Used to enforce uniqueness in a
**                                  CREATE UNIQUE INDEX statement.
**
**    sqlite3VdbeSorterClose()      Close the VdbeSorter object and reclaim
**                                  all resources.
**
**    sqlite3VdbeSorterReset()      Refurbish the VdbeSorter for reuse.  This
**                                  is like Close() followed by Init() only
**                                  much faster.
**
** The interfaces above must be called in a particular order.  Write() can
** only occur in between Init()/Reset() and Rewind().  Next(), Rowkey(), and
** Compare() can only occur in between Rewind() and Close()/Reset(). i.e.
**
**   Init()
**   for each record: Write()
**   Rewind()
**     Rowkey()/Compare()
**   Next()
**   Close()
**
** Algorithm:
**
** Records passed to the sorter via calls to Write() are initially held
** unsorted in main memory. Assuming the amount of memory used never exceeds
** a threshold, when Rewind() is called the set of records is sorted using
** an in-memory merge sort. In this case, no temporary files are required
** and subsequent calls to Rowkey(), Next() and Compare() read records
** directly from main memory.
**
** If the amount of space used to store records in main memory exceeds the
** threshold, then the set of records currently in memory are sorted and
** written to a temporary file in "Packed Memory Array" (PMA) format.
** A PMA created at this point is known as a "level-0 PMA". Higher levels
** of PMAs may be created by merging existing PMAs together - for example
** merging two or more level-0 PMAs together creates a level-1 PMA.
**
** The threshold for the amount of main memory to use before flushing
** records to a PMA is roughly the same as the limit configured for the
** page-cache of the main database. Specifically, the threshold is set to
** the value returned by "PRAGMA main.page_size" multiplied by
** that returned by "PRAGMA main.cache_size", in bytes.
**
** If the sorter is running in single-threaded mode, then all PMAs generated
** are appended to a single temporary file. Or, if the sorter is running in
** multi-threaded mode then up to (N+1) temporary files may be opened, where
** N is the configured number of worker threads. In this case, instead of
** sorting the records and writing the PMA to a temporary file itself, the
** calling thread usually launches a worker thread to do so. Except, if
** there are already N worker threads running, the main thread does the work
** itself.
**
** The sorter is running in multi-threaded mode if (a) the library was built
** with pre-processor symbol SQLITE_MAX_WORKER_THREADS set to a value greater
** than zero, and (b) worker threads have been enabled at runtime by calling
** "PRAGMA threads=N" with some value of N greater than 0.
**
** When Rewind() is called, any data remaining in memory is flushed to a
** final PMA. So at this point the data is stored in some number of sorted
** PMAs within temporary files on disk.
**
** If there are fewer than SORTER_MAX_MERGE_COUNT PMAs in total and the
** sorter is running in single-threaded mode, then these PMAs are merged
** incrementally as keys are retrieved from the sorter by the VDBE.  The
** MergeEngine object, described in further detail below, performs this
** merge.
**
** Or, if running in multi-threaded mode, then a background thread is
** launched to merge the existing PMAs. Once the background thread has
** merged T bytes of data into a single sorted PMA, the main thread
** begins reading keys from that PMA while the background thread proceeds
** with merging the next T bytes of data. And so on.
**
** Parameter T is set to half the value of the memory threshold used
** by Write() above to determine when to create a new PMA.
**
** If there are more than SORTER_MAX_MERGE_COUNT PMAs in total when
** Rewind() is called, then a hierarchy of incremental-merges is used.
** First, T bytes of data from the first SORTER_MAX_MERGE_COUNT PMAs on
** disk are merged together. Then T bytes of data from the second set, and
** so on, such that no operation ever merges more than SORTER_MAX_MERGE_COUNT
** PMAs at a time. This done is to improve locality.
**
** If running in multi-threaded mode and there are more than
** SORTER_MAX_MERGE_COUNT PMAs on disk when Rewind() is called, then more
** than one background thread may be created. Specifically, there may be
** one background thread for each temporary file on disk, and one background
** thread to merge the output of each of the others to a single PMA for
** the main thread to read from.

/*
** The MergeEngine object is used to combine two or more smaller PMAs into
** one big PMA using a merge operation.  Separate PMAs all need to be
** combined into one big PMA in order to be able to step through the sorted
** records in order.
**
** The aReadr[] array contains a PmaReader object for each of the PMAs being
** merged.  An aReadr[] object either points to a valid key or else is at EOF.
** ("EOF" means "End Of File".  When aReadr[] is at EOF there is no more data.)
** For the purposes of the paragraphs below, we assume that the array is
** actually N elements in size, where N is the smallest power of 2 greater
** to or equal to the number of PMAs being merged. The extra aReadr[] elements
** are treated as if they are empty (always at EOF).
**
** The aTree[] array is also N elements in size. The value of N is stored in
** the MergeEngine.nTree variable.
**
** The final (N/2) elements of aTree[] contain the results of comparing
** pairs of PMA keys together. Element i contains the result of
** comparing aReadr[2*i-N] and aReadr[2*i-N+1]. Whichever key is smaller, the
** aTree element is set to the index of it.
**
** For the purposes of this comparison, EOF is considered greater than any
** other key value. If the keys are equal (only possible with two EOF
** values), it doesn't matter which index is stored.
**
** The (N/4) elements of aTree[] that precede the final (N/2) described
** above contains the index of the smallest of each block of 4 PmaReaders
** And so on. So that aTree[1] contains the index of the PmaReader that
** currently points to the smallest key value. aTree[0] is unused.
**
** Example:
**
**     aReadr[0] -> Banana
**     aReadr[1] -> Feijoa
**     aReadr[2] -> Elderberry
**     aReadr[3] -> Currant
**     aReadr[4] -> Grapefruit
**     aReadr[5] -> Apple
**     aReadr[6] -> Durian
**     aReadr[7] -> EOF
**
**     aTree[] = { X, 5   0, 5    0, 3, 5, 6 }
**
** The current element is "Apple" (the value of the key indicated by
** PmaReader 5). When the Next() operation is invoked, PmaReader 5 will
** be advanced to the next key in its segment. Say the next key is
** "Eggplant":
**
**     aReadr[5] -> Eggplant
**
** The contents of aTree[] are updated first by comparing the new PmaReader
** 5 key to the current key of PmaReader 4 (still "Grapefruit"). The PmaReader
** 5 value is still smaller, so aTree[6] is set to 5. And so on up the tree.
** The value of PmaReader 6 - "Durian" - is now smaller than that of PmaReader
** 5, so aTree[3] is set to 6. Key 0 is smaller than key 6 (Banana<Durian),
** so the value written into element 1 of the array is 0. As follows:
**
**     aTree[] = { X, 0   0, 6    0, 3, 5, 6 }
**
** In other words, each time we advance to the next sorter element, log2(N)
** key comparison operations are required, where N is the number of segments
** being merged (rounded up to the next power of 2).

**
** There are two types of IncrMerger object - single (bUseThread==0) and

**
** A multi-threaded IncrMerger object uses two temporary files - aFile[0]
** and aFile[1]. Neither file is allowed to grow to more than mxSz bytes in
** size. When the IncrMerger is initialized, it reads enough data from
** pMerger to populate aFile[0]. It then sets variables within the
** corresponding PmaReader object to read from that file and kicks off
** a background thread to populate aFile[1] with the next mxSz bytes of
** sorted record data from pMerger.
**
** When the PmaReader reaches the end of aFile[0], it blocks until the
** background thread has finished populating aFile[1]. It then exchanges
** the contents of the aFile[0] and aFile[1] variables within this structure,
** sets the PmaReader fields to read from the new aFile[0] and kicks off
** another background thread to populate the new aFile[1]. And so on, until
** the contents of pMerger are exhausted.
**
** A single-threaded IncrMerger does not open any temporary files of its
** own. Instead, it has exclusive access to mxSz bytes of space beginning
** at offset iStartOff of file pTask->file2. And instead of using a
** background thread to prepare data for the PmaReader, with a single
** threaded IncrMerger the allocate part of pTask->file2 is "refilled" with
** keys from pMerger by the calling thread whenever the PmaReader runs out

** Update:  The in-memory journal is also used to temporarily cache
** smaller journals that are not critical for power-loss recovery.
** For example, statement journals that are not too big will be held
** entirely in memory, thus reducing the number of file I/O calls, and
** more importantly, reducing temporary file creation events.  If these
** journals become too large for memory, they are spilled to disk.  But

//	** This routine walks an expression tree and resolves references to
//	** table columns and result-set columns.  At the same time, do error
//	** checking on function usage and set a flag if any aggregate functions
//	** are seen.
//	**
//	** To resolve table columns references we look for nodes (or subtrees) of the
//	** form X.Y.Z or Y.Z or just Z where
//	**
//	**      X:   The name of a database.  Ex:  "main" or "temp" or
//	**           the symbolic name assigned to an ATTACH-ed database.
//	**
//	**      Y:   The name of a table in a FROM clause.  Or in a trigger
//	**           one of the special names "old" or "new".
//	**
//	**      Z:   The name of a column in table Y.
//	**
//	** The node at the root of the subtree is modified as follows:
//	**
//	**    Expr.op        Changed to TK_COLUMN
//	**    Expr.pTab      Points to the Table object for X.Y
//	**    Expr.iColumn   The column index in X.Y.  -1 for the rowid.
//	**    Expr.iTable    The VDBE cursor number for X.Y
//	**
//	**
//	** To resolve result-set references, look for expression nodes of the
//	** form Z (with no X and Y prefix) where the Z matches the right-hand
//	** size of an AS clause in the result-set of a SELECT.  The Z expression
//	** is replaced by a copy of the left-hand side of the result-set expression.
//	** Table-name and function resolution occurs on the substituted expression
//	** tree.  For example, in:
//	**
//	**      SELECT a+b AS x, c+d AS y FROM t1 ORDER BY x;
//	**
//	** The "x" term of the order by is replaced by "a+b" to render:
//	**
//	**      SELECT a+b AS x, c+d AS y FROM t1 ORDER BY a+b;
//	**
//	** Function calls are checked to make sure that the function is
//	** defined and that the correct number of arguments are specified.
//	** If the function is an aggregate function, then the NC_HasAgg flag is
//	** set and the opcode is changed from TK_FUNCTION to TK_AGG_FUNCTION.
//	** If an expression contains aggregate functions then the EP_Agg
//	** property on the expression is set.
//	**
//	** An error message is left in pParse if anything is amiss.  The number
//	** if errors is returned.

//	** be used either to test for membership in the RHS set or to iterate through
//	** all members of the RHS set, skipping duplicates.
//	**
//	** A cursor is opened on the b-tree object that is the RHS of the IN operator
//	** and the *piTab parameter is set to the index of that cursor.
//	**
//	** The returned value of this function indicates the b-tree type, as follows:
//	**
//	**   IN_INDEX_ROWID      - The cursor was opened on a database table.
//	**   IN_INDEX_INDEX_ASC  - The cursor was opened on an ascending index.
//	**   IN_INDEX_INDEX_DESC - The cursor was opened on a descending index.
//	**   IN_INDEX_EPH        - The cursor was opened on a specially created and
//	**                         populated ephemeral table.
//	**   IN_INDEX_NOOP       - No cursor was allocated.  The IN operator must be
//	**                         implemented as a sequence of comparisons.
//	**
//	** An existing b-tree might be used if the RHS expression pX is a simple
//	** subquery such as:
//	**
//	**     SELECT <column1>, <column2>... FROM <table>
//	**
//	** If the RHS of the IN operator is a list or a more complex subquery, then
//	** an ephemeral table might need to be generated from the RHS and then
//	** pX->iTable made to point to the ephemeral table instead of an
//	** existing table.  In this case, the creation and initialization of the
//	** ephemeral table might be put inside of a subroutine, the EP_Subrtn flag
//	** will be set on pX and the pX->y.sub fields will be set to show where
//	** the subroutine is coded.
//	**
//	** The inFlags parameter must contain, at a minimum, one of the bits
//	** IN_INDEX_MEMBERSHIP or IN_INDEX_LOOP but not both.  If inFlags contains
//	** IN_INDEX_MEMBERSHIP, then the generated table will be used for a fast
//	** membership test.  When the IN_INDEX_LOOP bit is set, the IN index will
//	** be used to loop over all values of the RHS of the IN operator.
//	**
//	** When IN_INDEX_LOOP is used (and the b-tree will be used to iterate
//	** through the set members) then the b-tree must not contain duplicates.
//	** An ephemeral table will be created unless the selected columns are guaranteed
//	** to be unique - either because it is an INTEGER PRIMARY KEY or due to
//	** a UNIQUE constraint or index.
//	**
//	** When IN_INDEX_MEMBERSHIP is used (and the b-tree will be used
//	** for fast set membership tests) then an ephemeral table must
//	** be used unless <columns> is a single INTEGER PRIMARY KEY column or an
//	** index can be found with the specified <columns> as its left-most.
//	**
//	** If the IN_INDEX_NOOP_OK and IN_INDEX_MEMBERSHIP are both set and
//	** if the RHS of the IN operator is a list (not a subquery) then this
//	** routine might decide that creating an ephemeral b-tree for membership
//	** testing is too expensive and return IN_INDEX_NOOP.  In that case, the
//	** calling routine should implement the IN operator using a sequence
//	** of Eq or Ne comparison operations.
//	**
//	** When the b-tree is being used for membership tests, the calling function
//	** might need to know whether or not the RHS side of the IN operator
//	** contains a NULL.  If prRhsHasNull is not a NULL pointer and
//	** if there is any chance that the (...) might contain a NULL value at
//	** runtime, then a register is allocated and the register number written
//	** to *prRhsHasNull. If there is no chance that the (...) contains a
//	** NULL value, then *prRhsHasNull is left unchanged.
//	**
//	** If a register is allocated and its location stored in *prRhsHasNull, then
//	** the value in that register will be NULL if the b-tree contains one or more
//	** NULL values, and it will be some non-NULL value if the b-tree contains no
//	** NULL values.
//	**
//	** If the aiMap parameter is not NULL, it must point to an array containing
//	** one element for each column returned by the SELECT statement on the RHS
//	** of the IN(...) operator. The i'th entry of the array is populated with the
//	** offset of the index column that matches the i'th column returned by the
//	** SELECT. For example, if the expression and selected index are:
//	**
//	**   (?,?,?) IN (SELECT a, b, c FROM t1)
//	**   CREATE INDEX i1 ON t1(b, c, a);
//	**
//	** then aiMap[] is populated with {2, 0, 1}.

**
*************************************************************************
** This file contains code associated with the ANALYZE command.
**
** The ANALYZE command gather statistics about the content of tables
** and indices.  These statistics are made available to the query planner
** to help it make better decisions about how to perform queries.
**
** The following system tables are or have been supported:
**
**    CREATE TABLE sqlite_stat1(tbl, idx, stat);
**    CREATE TABLE sqlite_stat2(tbl, idx, sampleno, sample);
**    CREATE TABLE sqlite_stat3(tbl, idx, nEq, nLt, nDLt, sample);
**    CREATE TABLE sqlite_stat4(tbl, idx, nEq, nLt, nDLt, sample);
**
** Additional tables might be added in future releases of SQLite.
** The sqlite_stat2 table is not created or used unless the SQLite version
** is between 3.6.18 and 3.7.8, inclusive, and unless SQLite is compiled
** with SQLITE_ENABLE_STAT2.  The sqlite_stat2 table is deprecated.
** The sqlite_stat2 table is superseded by sqlite_stat3, which is only
** created and used by SQLite versions 3.7.9 through 3.29.0 when
** SQLITE_ENABLE_STAT3 defined.  The functionality of sqlite_stat3
** is a superset of sqlite_stat2 and is also now deprecated.  The
** sqlite_stat4 is an enhanced version of sqlite_stat3 and is only
** available when compiled with SQLITE_ENABLE_STAT4 and in SQLite
** versions 3.8.1 and later.  STAT4 is the only variant that is still
** supported.
**
** For most applications, sqlite_stat1 provides all the statistics required
** for the query planner to make good choices.
**
** Format of sqlite_stat1:
**
** There is normally one row per index, with the index identified by the
** name in the idx column.  The tbl column is the name of the table to
** which the index belongs.  In each such row, the stat column will be
** a string consisting of a list of integers.  The first integer in this
** list is the number of rows in the index.  (This is the same as the
** number of rows in the table, except for partial indices.)  The second
** integer is the average number of rows in the index that have the same
** value in the first column of the index.  The third integer is the average
** number of rows in the index that have the same value for the first two
** columns.  The N-th integer (for N>1) is the average number of rows in
** the index which have the same value for the first N-1 columns.  For
** a K-column index, there will be K+1 integers in the stat column.  If
** the index is unique, then the last integer will be 1.
**
** The list of integers in the stat column can optionally be followed
** by the keyword "unordered".  The "unordered" keyword, if it is present,
** must be separated from the last integer by a single space.  If the
** "unordered" keyword is present, then the query planner assumes that
** the index is unordered and will not use the index for a range query.
**
** If the sqlite_stat1.idx column is NULL, then the sqlite_stat1.stat
** column contains a single integer which is the (estimated) number of
** rows in the table identified by sqlite_stat1.tbl.
**
** Format of sqlite_stat2:
**
** The sqlite_stat2 is only created and is only used if SQLite is compiled
** with SQLITE_ENABLE_STAT2 and if the SQLite version number is between
** 3.6.18 and 3.7.8.  The "stat2" table contains additional information
** about the distribution of keys within an index.  The index is identified by
** the "idx" column and the "tbl" column is the name of the table to which
** the index belongs.  There are usually 10 rows in the sqlite_stat2
** table for each index.
**
** The sqlite_stat2 entries for an index that have sampleno between 0 and 9
** inclusive are samples of the left-most key value in the index taken at
** evenly spaced points along the index.  Let the number of samples be S
** (10 in the standard build) and let C be the number of rows in the index.
** Then the sampled rows are given by:
**
**     rownumber = (i*C*2 + C)/(S*2)
**
** For i between 0 and S-1.  Conceptually, the index space is divided into
** S uniform buckets and the samples are the middle row from each bucket.
**
** The format for sqlite_stat2 is recorded here for legacy reference.  This
** version of SQLite does not support sqlite_stat2.  It neither reads nor
** writes the sqlite_stat2 table.  This version of SQLite only supports
** sqlite_stat3.
**
** Format for sqlite_stat3:
**
** The sqlite_stat3 format is a subset of sqlite_stat4.  Hence, the
** sqlite_stat4 format will be described first.  Further information
** about sqlite_stat3 follows the sqlite_stat4 description.
**
** Format for sqlite_stat4:
**
** As with sqlite_stat2, the sqlite_stat4 table contains histogram data
** to aid the query planner in choosing good indices based on the values
** that indexed columns are compared against in the WHERE clauses of
** queries.
**
** The sqlite_stat4 table contains multiple entries for each index.
** The idx column names the index and the tbl column is the table of the
** index.  If the idx and tbl columns are the same, then the sample is
** of the INTEGER PRIMARY KEY.  The sample column is a blob which is the
** binary encoding of a key from the index.  The nEq column is a
** list of integers.  The first integer is the approximate number
** of entries in the index whose left-most column exactly matches
** the left-most column of the sample.  The second integer in nEq
** is the approximate number of entries in the index where the
** first two columns match the first two columns of the sample.
** And so forth.  nLt is another list of integers that show the approximate
** number of entries that are strictly less than the sample.  The first
** integer in nLt contains the number of entries in the index where the
** left-most column is less than the left-most column of the sample.
** The K-th integer in the nLt entry is the number of index entries
** where the first K columns are less than the first K columns of the
** sample.  The nDLt column is like nLt except that it contains the
** number of distinct entries in the index that are less than the
** sample.
**
** There can be an arbitrary number of sqlite_stat4 entries per index.
** The ANALYZE command will typically generate sqlite_stat4 tables
** that contain between 10 and 40 samples which are distributed across
** the key space, though not uniformly, and which include samples with
** large nEq values.
**
** Format for sqlite_stat3 redux:
**
** The sqlite_stat3 table is like sqlite_stat4 except that it only
** looks at the left-most column of the index.  The sqlite_stat3.sample
** column contains the actual value of the left-most column instead
** of a blob encoding of the complete index key as is found in
** sqlite_stat4.sample.  The nEq, nLt, and nDLt entries of sqlite_stat3
** all contain just a single integer which is the same as the first
** integer in the equivalent columns in sqlite_stat4.

//	** various fields of the database.  The first argument to the auth function
//	** is a copy of the 3rd argument to this routine.  The second argument
//	** to the auth function is one of these constants:
//	**
//	**       SQLITE_CREATE_INDEX
//	**       SQLITE_CREATE_TABLE
//	**       SQLITE_CREATE_TEMP_INDEX
//	**       SQLITE_CREATE_TEMP_TABLE

//	** means that the SQL statement will never-run - the sqlite3_exec() call
//	** will return with an error.  SQLITE_IGNORE means that the SQL statement
//	** should run but attempts to read the specified column will return NULL
//	** and attempts to write the column will be ignored.
//	**
//	** Setting the auth function to NULL disables this hook.  The default

/*
** Deferred and Immediate FKs
** --------------------------
**
** Foreign keys in SQLite come in two flavours: deferred and immediate.
** If an immediate foreign key constraint is violated,
** SQLITE_CONSTRAINT_FOREIGNKEY is returned and the current
** statement transaction rolled back. If a
** deferred foreign key constraint is violated, no action is taken
** immediately. However if the application attempts to commit the
** transaction before fixing the constraint violation, the attempt fails.
**
** Deferred constraints are implemented using a simple counter associated
** with the database handle. The counter is set to zero each time a
** database transaction is opened. Each time a statement is executed
** that causes a foreign key violation, the counter is incremented. Each
** time a statement is executed that removes an existing violation from
** the database, the counter is decremented. When the transaction is
** committed, the commit fails if the current value of the counter is
** greater than zero. This scheme has two big drawbacks:
**
**   * When a commit fails due to a deferred foreign key constraint,
**     there is no way to tell which foreign constraint is not satisfied,
**     or which row it is not satisfied for.
**
**   * If the database contains foreign key violations when the
**     transaction is opened, this may cause the mechanism to malfunction.
**
** Despite these problems, this approach is adopted as it seems simpler
** than the alternatives.
**
** INSERT operations:
**
**   I.1) For each FK for which the table is the child table, search
**        the parent table for a match. If none is found increment the
**        constraint counter.
**
**   I.2) For each FK for which the table is the parent table,
**        search the child table for rows that correspond to the new
**        row in the parent table. Decrement the counter for each row
**        found (as the constraint is now satisfied).
**
** DELETE operations:
**
**   D.1) For each FK for which the table is the child table,
**        search the parent table for a row that corresponds to the
**        deleted row in the child table. If such a row is not found,
**        decrement the counter.
**
**   D.2) For each FK for which the table is the parent table, search
**        the child table for rows that correspond to the deleted row
**        in the parent table. For each found increment the counter.
**
** UPDATE operations:
**
**   An UPDATE command requires that all 4 steps above are taken, but only
**   for FK constraints for which the affected columns are actually
**   modified (values must be compared at runtime).
**
** Note that I.1 and D.1 are very similar operations, as are I.2 and D.2.
** This simplifies the implementation a bit.
**
** For the purposes of immediate FK constraints, the OR REPLACE conflict
** resolution is considered to delete rows before the new row is inserted.
** If a delete caused by OR REPLACE violates an FK constraint, an exception
** is thrown, even if the FK constraint would be satisfied after the new
** row is inserted.
**
** Immediate constraints are usually handled similarly. The only difference
** is that the counter used is stored as part of each individual statement
** object (struct Vdbe). If, after the statement has run, its immediate
** constraint counter is greater than zero,
** it returns SQLITE_CONSTRAINT_FOREIGNKEY
** and the statement transaction is rolled back. An exception is an INSERT
** statement that inserts a single row only (no triggers). In this case,
** instead of using a counter, an exception is thrown immediately if the
** INSERT violates a foreign key constraint. This is necessary as such
** an INSERT does not open a statement transaction.
**
** TODO: How should dropping a table be handled? How should renaming a
** table be handled?
**
**
** Query API Notes
** ---------------
**
** Before coding an UPDATE or DELETE row operation, the code-generator
** for those two operations needs to know whether or not the operation
** requires any FK processing and, if so, which columns of the original
** row are required by the FK processing VDBE code (i.e. if FKs were
** implemented using triggers, which of the old.* columns would be
** accessed). No information is required by the code-generator before
** coding an INSERT operation. The functions used by the UPDATE/DELETE
** generation code to query for this information are:
**
**   sqlite3FkRequired() - Test to see if FK processing is required.
**   sqlite3FkOldmask()  - Query for the set of required old.* columns.
**
**
** Externally accessible module functions
** --------------------------------------
**
**   sqlite3FkCheck()    - Check for foreign key violations.
**   sqlite3FkActions()  - Code triggers for ON UPDATE/ON DELETE actions.
**   sqlite3FkDelete()   - Delete an FKey structure.
 */

/*
** VDBE Calling Convention
** -----------------------
**
** Example:
**
**   For the following INSERT statement:
**
**     CREATE TABLE t1(a, b INTEGER PRIMARY KEY, c);
**     INSERT INTO t1 VALUES(1, 2, 3.1);
**
**   Register (x):        2    (type integer)
**   Register (x+1):      1    (type integer)
**   Register (x+2):      NULL (type NULL)
**   Register (x+3):      3.1  (type real)
 */

// C documentation
//
//	/*
//	** A foreign key constraint requires that the key columns in the parent
//	** table are collectively subject to a UNIQUE or PRIMARY KEY constraint.
//	** Given that pParent is the parent table for foreign key constraint pFKey,
//	** search the schema for a unique index on the parent key columns.
//	**
//	** If successful, zero is returned. If the parent key is an INTEGER PRIMARY
//	** KEY column, then output variable *ppIdx is set to NULL. Otherwise, *ppIdx
//	** is set to point to the unique index.
//	**

//	** This routine is called to handle SQL of the following forms:
//	**
//	**    insert into TABLE (IDLIST) values(EXPRLIST),(EXPRLIST),...
//	**    insert into TABLE (IDLIST) select
//	**    insert into TABLE (IDLIST) default values
//	**
//	** The IDLIST following the table name is always optional.  If omitted,
//	** then a list of all (non-hidden) columns for the table is substituted.
//	** The IDLIST appears in the pColumn parameter.  pColumn is NULL if IDLIST
//	** is omitted.
//	**
//	** For the pSelect parameter holds the values to be inserted for the
//	** first two forms shown above.  A VALUES clause is really just short-hand
//	** for a SELECT statement that omits the FROM clause and everything else
//	** that follows.  If the pSelect parameter is NULL, that means that the
//	** DEFAULT VALUES form of the INSERT statement is intended.
//	**
//	** The code generated follows one of four templates.  For a simple
//	** insert with data coming from a single-row VALUES clause, the code executes
//	** once straight down through.  Pseudo-code follows (we call this
//	** the "1st template"):
//	**
//	**         open write cursor to <table> and its indices
//	**         put VALUES clause expressions into registers
//	**         write the resulting record into <table>
//	**         cleanup
//	**
//	** The three remaining templates assume the statement is of the form
//	**
//	**   INSERT INTO <table> SELECT ...
//	**
//	** If the SELECT clause is of the restricted form "SELECT * FROM <table2>" -
//	** in other words if the SELECT pulls all columns from a single table
//	** and there is no WHERE or LIMIT or GROUP BY or ORDER BY clauses, and
//	** if <table2> and <table1> are distinct tables but have identical
//	** schemas, including all the same indices, then a special optimization
//	** is invoked that copies raw records from <table2> over to <table1>.
//	** See the xferOptimization() function for the implementation of this
//	** template.  This is the 2nd template.
//	**
//	**         open a write cursor to <table>
//	**         open read cursor on <table2>
//	**         transfer all records in <table2> over to <table>
//	**         close cursors
//	**         foreach index on <table>
//	**           open a write cursor on the <table> index
//	**           open a read cursor on the corresponding <table2> index
//	**           transfer all records from the read to the write cursors
//	**           close cursors
//	**         end foreach
//	**
//	** The 3rd template is for when the second template does not apply
//	** and the SELECT clause does not read from <table> at any time.
//	** The generated code follows this template:
//	**
//	**         X <- A
//	**         goto B
//	**      A: setup for the SELECT
//	**         loop over the rows in the SELECT
//	**           load values into registers R..R+n
//	**           yield X
//	**         end loop
//	**         cleanup after the SELECT
//	**         end-coroutine X
//	**      B: open write cursor to <table> and its indices
//	**      C: yield X, at EOF goto D
//	**         insert the select result into <table> from R..R+n
//	**         goto C
//	**      D: cleanup
//	**
//	** The 4th template is used if the insert statement takes its
//	** values from a SELECT but the data is being inserted into a table
//	** that is also read as part of the SELECT.  In the third form,
//	** we have to use an intermediate table to store the results of
//	** the select.  The template is like this:
//	**
//	**         X <- A
//	**         goto B
//	**      A: setup for the SELECT
//	**         loop over the tables in the SELECT
//	**           load value into register R..R+n
//	**           yield X
//	**         end loop
//	**         cleanup after the SELECT
//	**         end co-routine R
//	**      B: open temp table
//	**      L: yield X, at EOF goto M
//	**         insert row from R..R+n into temp table
//	**         goto L
//	**      M: open write cursor to <table> and its indices
//	**         rewind temp table
//	**      C: loop over rows of intermediate table
//	**           transfer values form intermediate table into <table>
//	**         end loop
//	**      D: cleanup

//	** Generate code to do constraint checks prior to an INSERT or an UPDATE
//	** on table pTab.
//	**
//	** The regNewData parameter is the first register in a range that contains
//	** the data to be inserted or the data after the update.  There will be
//	** pTab->nCol+1 registers in this range.  The first register (the one
//	** that regNewData points to) will contain the new rowid, or NULL in the
//	** case of a WITHOUT ROWID table.  The second register in the range will
//	** contain the content of the first table column.  The third register will
//	** contain the content of the second table column.  And so forth.
//	**
//	** The regOldData parameter is similar to regNewData except that it contains
//	** the data prior to an UPDATE rather than afterwards.  regOldData is zero
//	** for an INSERT.  This routine can distinguish between UPDATE and INSERT by
//	** checking regOldData for zero.
//	**
//	** For an UPDATE, the pkChng boolean is true if the true primary key (the
//	** rowid for a normal table or the PRIMARY KEY for a WITHOUT ROWID table)
//	** might be modified by the UPDATE.  If pkChng is false, then the key of
//	** the iDataCur content table is guaranteed to be unchanged by the UPDATE.
//	**
//	** For an INSERT, the pkChng boolean indicates whether or not the rowid
//	** was explicitly specified as part of the INSERT statement.  If pkChng
//	** is zero, it means that the either rowid is computed automatically or
//	** that the table is a WITHOUT ROWID table and has no rowid.  On an INSERT,
//	** pkChng will only be true if the INSERT statement provides an integer
//	** value for either the rowid column or its INTEGER PRIMARY KEY alias.
//	**
//	** The code generated by this routine will store new index entries into
//	** registers identified by aRegIdx[].  No index entry is created for
//	** indices where aRegIdx[i]==0.  The order of indices in aRegIdx[] is
//	** the same as the order of indices on the linked list of indices
//	** at pTab->pIndex.
//	**
//	** (2019-05-07) The generated code also creates a new record for the
//	** main table, if pTab is a rowid table, and stores that record in the
//	** register identified by aRegIdx[nIdx] - in other words in the first
//	** entry of aRegIdx[] past the last index.  It is important that the
//	** record be generated during constraint checks to avoid affinity changes
//	** to the register content that occur after constraint checks but before
//	** the new record is inserted.
//	**
//	** The caller must have already opened writeable cursors on the main
//	** table and all applicable indices (that is to say, all indices for which
//	** aRegIdx[] is not zero).  iDataCur is the cursor for the main table when
//	** inserting or updating a rowid table, or the cursor for the PRIMARY KEY
//	** index when operating on a WITHOUT ROWID table.  iIdxCur is the cursor
//	** for the first index in the pTab->pIndex list.  Cursors for other indices
//	** are at iIdxCur+N for the N-th element of the pTab->pIndex list.
//	**
//	** This routine also generates code to check constraints.  NOT NULL,
//	** CHECK, and UNIQUE constraints are all checked.  If a constraint fails,
//	** then the appropriate action is performed.  There are five possible
//	** actions: ROLLBACK, ABORT, FAIL, REPLACE, and IGNORE.
//	**
//	**  Constraint type  Action       What Happens
//	**  ---------------  ----------   ----------------------------------------
//	**  any              ROLLBACK     The current transaction is rolled back and
//	**                                sqlite3_step() returns immediately with a
//	**                                return code of SQLITE_CONSTRAINT.
//	**
//	**  any              ABORT        Back out changes from the current command
//	**                                only (do not do a complete rollback) then
//	**                                cause sqlite3_step() to return immediately
//	**                                with SQLITE_CONSTRAINT.
//	**
//	**  any              FAIL         Sqlite3_step() returns immediately with a
//	**                                return code of SQLITE_CONSTRAINT.  The
//	**                                transaction is not rolled back and any
//	**                                changes to prior rows are retained.
//	**
//	**  any              IGNORE       The attempt in insert or update the current
//	**                                row is skipped, without throwing an error.
//	**                                Processing continues with the next row.
//	**                                (There is an immediate jump to ignoreDest.)
//	**
//	**  NOT NULL         REPLACE      The NULL value is replace by the default
//	**                                value for that column.  If the default value
//	**                                is NULL, the action is the same as ABORT.
//	**
//	**  UNIQUE           REPLACE      The other row that conflicts with the row
//	**                                being inserted is removed.
//	**
//	**  CHECK            REPLACE      Illegal.  The results in an exception.
//	**
//	** Which action to take is determined by the overrideError parameter.
//	** Or if overrideError==OE_Default, then the pParse->onError parameter
//	** is used.  Or if pParse->onError==OE_Default then the onError value
//	** for the constraint is used.

	 **   (C)  Unique index that do use OE_Replace by default.

		 ** DETERMINATION OF WHEN TO RUN ANALYZE
		 **
		 ** In the current implementation, a table is analyzed if only if all of
		 ** the following are true:
		 **
		 ** (1) MASK bit 0x02 is set.
		 **
		 ** (2) The query planner used sqlite_stat1-style statistics for one or
		 **     more indexes of the table at some point during the lifetime of
		 **     the current connection.
		 **
		 ** (3) One or more indexes of the table are currently unanalyzed OR
		 **     the number of rows in the table has increased by 25 times or more
		 **     since the last time ANALYZE was run.
		 **
		 ** The rules for when tables are analyzed are likely to change in
		 ** future releases.

//	**
//	**     Parameter iTab is the cursor number of an ephemeral table that must
//	**     be opened before the VM code generated by this routine is executed.
//	**     The ephemeral cursor table is queried for a record identical to the
//	**     record formed by the current array of registers. If one is found,
//	**     jump to VM address addrRepeat. Otherwise, insert a new record into
//	**     the ephemeral cursor and proceed.
//	**
//	**     The returned value in this case is a copy of parameter iTab.
//	**
//	**   WHERE_DISTINCT_ORDERED:
//	**     In this case rows are being delivered sorted order. The ephemeral
//	**     table is not required. Instead, the current set of values
//	**     is compared against previous row. If they match, the new row
//	**     is not distinct and control jumps to VM address addrRepeat. Otherwise,
//	**     the VM program proceeds with processing the new row.
//	**
//	**     The returned value in this case is the register number of the first
//	**     in an array of registers used to store the previous result row so that
//	**     it can be compared to the next. The caller must ensure that this
//	**     register is initialized to NULL.  (The fixDistinctOpenEph() routine
//	**     will take care of this initialization.)
//	**
//	**   WHERE_DISTINCT_UNIQUE:
//	**     In this case it has already been determined that the rows are distinct.
//	**     No special action is required. The return value is zero.
//	**
//	** Parameter pEList is the list of expressions used to generated the
//	** contents of each row. It is used by this routine to determine (a)
//	** how many elements there are in the array of registers and (b) the
//	** collation sequences that should be used for the comparisons if

//	** Alternative compound select code generator for cases when there
//	** is an ORDER BY clause.
//	**
//	** We assume a query of the following form:
//	**
//	**      <selectA>  <operator>  <selectB>  ORDER BY <orderbylist>
//	**
//	** <operator> is one of UNION ALL, UNION, EXCEPT, or INTERSECT.  The idea
//	** is to code both <selectA> and <selectB> with the ORDER BY clause as
//	** co-routines.  Then run the co-routines in parallel and merge the results
//	** into the output.  In addition to the two coroutines (called selectA and
//	** selectB) there are 7 subroutines:
//	**
//	**    outA:    Move the output of the selectA coroutine into the output
//	**             of the compound query.
//	**
//	**    outB:    Move the output of the selectB coroutine into the output
//	**             of the compound query.  (Only generated for UNION and
//	**             UNION ALL.  EXCEPT and INSERTSECT never output a row that
//	**             appears only in B.)
//	**
//	**    AltB:    Called when there is data from both coroutines and A<B.
//	**
//	**    AeqB:    Called when there is data from both coroutines and A==B.
//	**
//	**    AgtB:    Called when there is data from both coroutines and A>B.
//	**
//	**    EofA:    Called when data is exhausted from selectA.
//	**
//	**    EofB:    Called when data is exhausted from selectB.
//	**
//	** The implementation of the latter five subroutines depend on which
//	** <operator> is used:
//	**
//	**
//	**             UNION ALL         UNION            EXCEPT          INTERSECT
//	**          -------------  -----------------  --------------  -----------------
//	**   AltB:   outA, nextA      outA, nextA       outA, nextA         nextA
//	**
//	**   AeqB:   outA, nextA         nextA             nextA         outA, nextA
//	**
//	**   AgtB:   outB, nextB      outB, nextB          nextB            nextB
//	**
//	**   EofA:   outB, nextB      outB, nextB          halt             halt
//	**
//	**   EofB:   outA, nextA      outA, nextA       outA, nextA         halt
//	**
//	** In the AltB, AeqB, and AgtB subroutines, an EOF on A following nextA
//	** causes an immediate jump to EofA and an EOF on B following nextB causes
//	** an immediate jump to EofB.  Within EofA and EofB, and EOF on entry or
//	** following nextX causes a jump to the end of the select processing.
//	**
//	** Duplicate removal in the UNION, EXCEPT, and INTERSECT cases is handled
//	** within the output subroutine.  The regPrev register set holds the previously
//	** output value.  A comparison is made against this value and the output
//	** is skipped if the next results would be the same as the previous.
//	**
//	** The implementation plan is to implement the two coroutines and seven
//	** subroutines first, then put the control logic at the bottom.  Like this:
//	**
//	**          goto Init
//	**     coA: coroutine for left query (A)
//	**     coB: coroutine for right query (B)
//	**    outA: output one row of A
//	**    outB: output one row of B (UNION and UNION ALL only)
//	**    EofA: ...
//	**    EofB: ...
//	**    AltB: ...
//	**    AeqB: ...
//	**    AgtB: ...
//	**    Init: initialize coroutine registers
//	**          yield coA
//	**          if eof(A) goto EofA
//	**          yield coB
//	**          if eof(B) goto EofB
//	**    Cmpr: Compare A, B
//	**          Jump AltB, AeqB, AgtB
//	**     End: ...
//	**
//	** We call AltB, AeqB, AgtB, EofA, and EofB "subroutines" but they are not
//	** actually called using Gosub and they do not Return.  EofA and EofB loop
//	** until all data is exhausted then jump to the "end" label.  AltB, AeqB,
//	** and AgtB jump to either L2 or to one of EofA or EofB.

//	** All references to columns in table iTable are to be replaced by corresponding
//	** expressions in pEList.
//	**
//	** ## About "isOuterJoin":
//	**
//	** The isOuterJoin column indicates that the replacement will occur into a
//	** position in the parent that NULL-able due to an OUTER JOIN.  Either the
//	** target slot in the parent is the right operand of a LEFT JOIN, or one of
//	** the left operands of a RIGHT JOIN.  In either case, we need to potentially
//	** bypass the substituted expression with OP_IfNullRow.
//	**
//	** Suppose the original expression is an integer constant. Even though the table
//	** has the nullRow flag set, because the expression is an integer constant,
//	** it will not be NULLed out.  So instead, we insert an OP_IfNullRow opcode
//	** that checks to see if the nullRow flag is set on the table.  If the nullRow
//	** flag is set, then the value in the register is set to NULL and the original
//	** expression is bypassed.  If the nullRow flag is not set, then the original
//	** expression runs to populate the register.
//	**
//	** Example where this is needed:
//	**
//	**      CREATE TABLE t1(a INTEGER PRIMARY KEY, b INT);
//	**      CREATE TABLE t2(x INT UNIQUE);
//	**
//	**      SELECT a,b,m,x FROM t1 LEFT JOIN (SELECT 59 AS m,x FROM t2) ON b=x;
//	**
//	** When the subquery on the right side of the LEFT JOIN is flattened, we
//	** have to add OP_IfNullRow in front of the OP_Integer that implements the
//	** "m" value of the subquery so that a NULL will be loaded instead of 59
//	** when processing a non-matched row of the left.

//	/*
//	** This routine attempts to flatten subqueries as a performance optimization.
//	** This routine returns 1 if it makes changes and 0 if no flattening occurs.
//	**
//	** To understand the concept of flattening, consider the following
//	** query:
//	**
//	**     SELECT a FROM (SELECT x+y AS a FROM t1 WHERE z<100) WHERE a>5
//	**
//	** The default way of implementing this query is to execute the
//	** subquery first and store the results in a temporary table, then
//	** run the outer query on that temporary table.  This requires two
//	** passes over the data.  Furthermore, because the temporary table
//	** has no indices, the WHERE clause on the outer query cannot be
//	** optimized.
//	**
//	** This routine attempts to rewrite queries such as the above into
//	** a single flat select, like this:
//	**
//	**     SELECT x+y AS a FROM t1 WHERE z<100 AND a>5
//	**
//	** The code generated for this simplification gives the same result
//	** but only has to scan the data once.  And because indices might
//	** exist on the table t1, a complete scan of the data might be
//	** avoided.
//	**
//	** Flattening is subject to the following constraints:
//	**
//	**  (**)  We no longer attempt to flatten aggregate subqueries. Was:
//	**        The subquery and the outer query cannot both be aggregates.
//	**
//	**  (**)  We no longer attempt to flatten aggregate subqueries. Was:
//	**        (2) If the subquery is an aggregate then
//	**        (2a) the outer query must not be a join and
//	**        (2b) the outer query must not use subqueries
//	**             other than the one FROM-clause subquery that is a candidate
//	**             for flattening.  (This is due to ticket [2f7170d73bf9abf80]
//	**             from 2015-02-09.)
//	**
//	**   (3)  If the subquery is the right operand of a LEFT JOIN then
//	**        (3a) the subquery may not be a join and
//	**        (3b) the FROM clause of the subquery may not contain a virtual
//	**             table and
//	**        (**) Was: "The outer query may not have a GROUP BY." This case
//	**             is now managed correctly
//	**        (3d) the outer query may not be DISTINCT.
//	**        See also (26) for restrictions on RIGHT JOIN.
//	**
//	**   (4)  The subquery can not be DISTINCT.
//	**
//	**  (**)  At one point restrictions (4) and (5) defined a subset of DISTINCT
//	**        sub-queries that were excluded from this optimization. Restriction
//	**        (4) has since been expanded to exclude all DISTINCT subqueries.
//	**
//	**  (**)  We no longer attempt to flatten aggregate subqueries.  Was:
//	**        If the subquery is aggregate, the outer query may not be DISTINCT.
//	**
//	**   (7)  The subquery must have a FROM clause.  TODO:  For subqueries without
//	**        A FROM clause, consider adding a FROM clause with the special
//	**        table sqlite_once that consists of a single row containing a
//	**        single NULL.
//	**
//	**   (8)  If the subquery uses LIMIT then the outer query may not be a join.
//	**
//	**   (9)  If the subquery uses LIMIT then the outer query may not be aggregate.
//	**
//	**  (**)  Restriction (10) was removed from the code on 2005-02-05 but we
//	**        accidentally carried the comment forward until 2014-09-15.  Original
//	**        constraint: "If the subquery is aggregate then the outer query
//	**        may not use LIMIT."
//	**
//	**  (11)  The subquery and the outer query may not both have ORDER BY clauses.
//	**
//	**  (**)  Not implemented.  Subsumed into restriction (3).  Was previously
//	**        a separate restriction deriving from ticket #350.
//	**
//	**  (13)  The subquery and outer query may not both use LIMIT.
//	**
//	**  (14)  The subquery may not use OFFSET.
//	**
//	**  (15)  If the outer query is part of a compound select, then the
//	**        subquery may not use LIMIT.
//	**        (See ticket #2339 and ticket [02a8e81d44]).
//	**
//	**  (16)  If the outer query is aggregate, then the subquery may not
//	**        use ORDER BY.  (Ticket #2942)  This used to not matter
//	**        until we introduced the group_concat() function.
//	**
//	**  (17)  If the subquery is a compound select, then
//	**        (17a) all compound operators must be a UNION ALL, and
//	**        (17b) no terms within the subquery compound may be aggregate
//	**              or DISTINCT, and
//	**        (17c) every term within the subquery compound must have a FROM clause
//	**        (17d) the outer query may not be
//	**              (17d1) aggregate, or
//	**              (17d2) DISTINCT
//	**        (17e) the subquery may not contain window functions, and
//	**        (17f) the subquery must not be the RHS of a LEFT JOIN.
//	**        (17g) either the subquery is the first element of the outer
//	**              query or there are no RIGHT or FULL JOINs in any arm
//	**              of the subquery.  (This is a duplicate of condition (27b).)
//	**        (17h) The corresponding result set expressions in all arms of the
//	**              compound must have the same affinity.
//	**
//	**        The parent and sub-query may contain WHERE clauses. Subject to
//	**        rules (11), (13) and (14), they may also contain ORDER BY,
//	**        LIMIT and OFFSET clauses.  The subquery cannot use any compound
//	**        operator other than UNION ALL because all the other compound
//	**        operators have an implied DISTINCT which is disallowed by
//	**        restriction (4).
//	**
//	**        Also, each component of the sub-query must return the same number
//	**        of result columns. This is actually a requirement for any compound
//	**        SELECT statement, but all the code here does is make sure that no
//	**        such (illegal) sub-query is flattened. The caller will detect the
//	**        syntax error and return a detailed message.
//	**
//	**  (18)  If the sub-query is a compound select, then all terms of the
//	**        ORDER BY clause of the parent must be copies of a term returned
//	**        by the parent query.
//	**
//	**  (19)  If the subquery uses LIMIT then the outer query may not
//	**        have a WHERE clause.
//	**
//	**  (20)  If the sub-query is a compound select, then it must not use
//	**        an ORDER BY clause.  Ticket #3773.  We could relax this constraint
//	**        somewhat by saying that the terms of the ORDER BY clause must
//	**        appear as unmodified result columns in the outer query.  But we
//	**        have other optimizations in mind to deal with that case.
//	**
//	**  (21)  If the subquery uses LIMIT then the outer query may not be
//	**        DISTINCT.  (See ticket [752e1646fc]).
//	**
//	**  (22)  The subquery may not be a recursive CTE.
//	**
//	**  (23)  If the outer query is a recursive CTE, then the sub-query may not be
//	**        a compound query.  This restriction is because transforming the
//	**        parent to a compound query confuses the code that handles
//	**        recursive queries in multiSelect().
//	**
//	**  (**)  We no longer attempt to flatten aggregate subqueries.  Was:
//	**        The subquery may not be an aggregate that uses the built-in min() or
//	**        or max() functions.  (Without this restriction, a query like:
//	**        "SELECT x FROM (SELECT max(y), x FROM t1)" would not necessarily
//	**        return the value X for which Y was maximal.)
//	**
//	**  (25)  If either the subquery or the parent query contains a window
//	**        function in the select list or ORDER BY clause, flattening
//	**        is not attempted.
//	**
//	**  (26)  The subquery may not be the right operand of a RIGHT JOIN.
//	**        See also (3) for restrictions on LEFT JOIN.
//	**
//	**  (27)  The subquery may not contain a FULL or RIGHT JOIN unless it
//	**        is the first element of the parent query.  Two subcases:
//	**        (27a) the subquery is not a compound query.
//	**        (27b) the subquery is a compound query and the RIGHT JOIN occurs
//	**              in any arm of the compound query.  (See also (17g).)
//	**
//	**  (28)  The subquery is not a MATERIALIZED CTE.  (This is handled
//	**        in the caller before ever reaching this routine.)
//	**
//	**
//	** In this routine, the "p" parameter is a pointer to the outer query.
//	** The subquery is p->pSrc->a[iFrom].  isAgg is true if the outer query
//	** uses aggregates.
//	**
//	** If flattening is not attempted, this routine is a no-op and returns 0.
//	** If flattening is attempted this routine returns 1.
//	**
//	** All of the expression analysis must occur on both the outer query and
//	** the subquery before this routine runs.

//	**      SELECT * FROM t1, t2, t3 WHERE t1.a=39 AND t2.b=t1.a AND t3.c=t2.b
//	**
//	** Is transformed into
//	**
//	**      SELECT * FROM t1, t2, t3 WHERE t1.a=39 AND t2.b=39 AND t3.c=39
//	**
//	** Return true if any transformations where made and false if not.
//	**
//	** Implementation note:  Constant propagation is tricky due to affinity
//	** and collating sequence interactions.  Consider this example:
//	**
//	**    CREATE TABLE t1(a INT,b TEXT);
//	**    INSERT INTO t1 VALUES(123,'0123');
//	**    SELECT * FROM t1 WHERE a=123 AND b=a;
//	**    SELECT * FROM t1 WHERE a=123 AND b=123;
//	**
//	** The two SELECT statements above should return different answers.  b=a
//	** is always true because the comparison uses numeric affinity, but b=123
//	** is false because it uses text affinity and '0123' is not the same as '123'.
//	** To work around this, the expression tree is not actually changed from
//	** "b=a" to "b=123" but rather the "a" in "b=a" is tagged with EP_FixedCol
//	** and the "123" value is hung off of the pLeft pointer.  Code generator
//	** routines know to generate the constant "123" instead of looking up the
//	** column value.  Also, to avoid collation problems, this optimization is
//	** only attempted if the "a=123" term uses the default BINARY collation.
//	**
//	** 2021-05-25 forum post 6a06202608: Another troublesome case is...
//	**
//	**    CREATE TABLE t1(x);
//	**    INSERT INTO t1 VALUES(10.0);
//	**    SELECT 1 FROM t1 WHERE x=10 AND x LIKE 10;
//	**
//	** The query should return no rows, because the t1.x value is '10.0' not '10'
//	** and '10.0' is not LIKE '10'.  But if we are not careful, the first WHERE
//	** term "x=10" will cause the second WHERE term to become "10 LIKE 10",
//	** resulting in a false positive.  To avoid this, constant propagation for
//	** columns with BLOB affinity is only allowed if the constant is used with
//	** operators ==, <=, <, >=, >, or IS in a way that will cause the correct
//	** type conversions to occur.  See logic associated with the bHasAffBlob flag
//	** for details.

//	**     WHERE x=5 AND y=10;
//	**
//	** The hope is that the terms added to the inner query will make it more

//	**           disallow this optimization for aggregate subqueries, but now
//	**           it is allowed by putting the extra terms on the HAVING clause.
//	**           The added HAVING clause is pointless if the subquery lacks
//	**           a GROUP BY clause.  But such a HAVING clause is also harmless
//	**           so there does not appear to be any reason to add extra logic
//	**           to suppress it. **)
//	**
//	**   (2) The inner query is the recursive part of a common table expression.
//	**
//	**   (3) The inner query has a LIMIT clause (since the changes to the WHERE
//	**       clause would change the meaning of the LIMIT).
//	**
//	**   (4) The inner query is the right operand of a LEFT JOIN and the
//	**       expression to be pushed down does not come from the ON clause
//	**       on that LEFT JOIN.
//	**
//	**   (5) The WHERE clause expression originates in the ON or USING clause
//	**       of a LEFT JOIN where iCursor is not the right-hand table of that
//	**       left join.  An example:
//	**
//	**           SELECT *
//	**           FROM (SELECT 1 AS a1 UNION ALL SELECT 2) AS aa
//	**           JOIN (SELECT 1 AS b2 UNION ALL SELECT 2) AS bb ON (a1=b2)
//	**           LEFT JOIN (SELECT 8 AS c3 UNION ALL SELECT 9) AS cc ON (b2=2);
//	**
//	**       The correct answer is three rows:  (1,1,NULL),(2,2,8),(2,2,9).
//	**       But if the (b2=2) term were to be pushed down into the bb subquery,
//	**       then the (1,1,NULL) row would be suppressed.
//	**
//	**   (6) Window functions make things tricky as changes to the WHERE clause
//	**       of the inner query could change the window over which window
//	**       functions are calculated. Therefore, do not attempt the optimization
//	**       if:
//	**
//	**     (6a) The inner query uses multiple incompatible window partitions.
//	**
//	**     (6b) The inner query is a compound and uses window-functions.
//	**
//	**     (6c) The WHERE clause does not consist entirely of constants and
//	**          copies of expressions found in the PARTITION BY clause of
//	**          all window-functions used by the sub-query. It is safe to
//	**          filter out entire partitions, as this does not change the
//	**          window over which any window-function is calculated.
//	**
//	**   (7) The inner query is a Common Table Expression (CTE) that should
//	**       be materialized.  (This restriction is implemented in the calling
//	**       routine.)
//	**
//	**   (8) If the subquery is a compound that uses UNION, INTERSECT,
//	**       or EXCEPT, then all of the result set columns for all arms of
//	**       the compound must use the BINARY collating sequence.
//	**
//	**   (9) All three of the following are true:
//	**
//	**       (9a) The WHERE clause expression originates in the ON or USING clause
//	**            of a join (either an INNER or an OUTER join), and
//	**
//	**       (9b) The subquery is to the right of the ON/USING clause
//	**
//	**       (9c) There is a RIGHT JOIN (or FULL JOIN) in between the ON/USING
//	**            clause and the subquery.
//	**
//	**       Without this restriction, the push-down optimization might move
//	**       the ON/USING filter expression from the left side of a RIGHT JOIN
//	**       over to the right side, which leads to incorrect answers.  See
//	**       also restriction (6) in sqlite3ExprIsSingleTableConstraint().
//	**
//	**  (10) The inner query is not the right-hand table of a RIGHT JOIN.
//	**
//	**  (11) The subquery is not a VALUES clause
//	**
//	** Return 0 if no changes are made and non-zero if one or more WHERE clause
//	** terms are duplicated into the subquery.

//	** The most recently coded instruction was an OP_Column to retrieve the
//	** i-th column of table pTab. This routine sets the P4 parameter of the
//	** OP_Column to the default value, if any.
//	**
//	** The default value of a column is specified by a DEFAULT clause in the
//	** column definition. This was either supplied by the user when the table
//	** was created, or added later to the table definition by an ALTER TABLE
//	** command. If the latter, then the row-records in the table btree on disk
//	** may not contain a value for the column and the default value, taken
//	** from the P4 parameter of the OP_Column instruction, is returned instead.
//	** If the former, then all row-records are guaranteed to include a value
//	** for the column and the P4 value is not required.
//	**
//	** Column definitions created by an ALTER TABLE command may only have
//	** literal default values specified: a number, null or a string. (If a more
//	** complicated default expression value was provided, it is evaluated
//	** when the ALTER TABLE is executed and one of the literal values written
//	** into the sqlite_schema table.)
//	**
//	** Therefore, the P4 parameter is only required if the default value for
//	** the column is a literal number, string or null. The sqlite3ValueFromExpr()
//	** function is capable of transforming these types of expressions into
//	** sqlite3_value objects.
//	**
//	** If column as REAL affinity and the table is an ordinary b-tree table
//	** (not a virtual table) then the value might have been stored as an
//	** integer.  In that case, add an OP_RealAffinity opcode to make sure
//	** it has been converted into REAL.

//	** The VACUUM command is used to clean up the database,

//	**
//	**   (1)  Create a new transient database file
//	**   (2)  Copy all content from the database being vacuumed into
//	**        the new transient database file
//	**   (3)  Copy content from the transient database back into the
//	**        original database.
//	**
//	** The transient database requires temporary disk space approximately
//	** equal to the size of the original database.  The copy operation of
//	** step (3) requires additional temporary disk space approximately equal
//	** to the size of the original database for the rollback journal.
//	** Hence, temporary disk space that is approximately 2x the size of the
//	** original database is required.  Every page of the database is written
//	** approximately 3 times:  Once for step (2) and twice for step (3).
//	** Two writes per page are required in step (3) because the original
//	** database content must be written into the rollback journal prior to
//	** overwriting the database with the vacuumed content.
//	**
//	** Only 1x temporary space and only 1x writes would be required if
//	** the copy of step (3) were replaced by deleting the original database
//	** and renaming the transient database as the original.  But that will
//	** not work if other processes are attached to the original database.
//	** And a power loss in between deleting the original and renaming the

** The query generator uses an array of instances of this structure to

** clause subexpression is separated from the others by AND operators,
** usually, or sometimes subexpressions separated by OR.
**
** All WhereTerms are collected into a single WhereClause structure.
** The following identity holds:
**
**        WhereTerm.pWC->a[WhereTerm.idx] == WhereTerm
**
** When a term is of the form:
**
**              X <op> <expr>
**
** where X is a column name and <op> is one of certain operators,
** then WhereTerm.leftCursor and WhereTerm.u.leftColumn record the
** cursor number and column number for X.  WhereTerm.eOperator records
** the <op> using a bitmask encoding defined by WO_xxx below.  The
** use of a bitmask encoding for the operator allows us to search
** quickly for terms that match any of several different operators.
**
** A WhereTerm might also be two or more subterms connected by OR:
**
**         (t1.X <op> <expr>) OR (t1.Y <op> <expr>) OR ....
**
** In this second case, wtFlag has the TERM_ORINFO bit set and eOperator==WO_OR
** and the WhereTerm.u.pOrInfo field points to auxiliary information that
** is collected about the OR clause.
**
** If a term in the WHERE clause does not match either of the two previous
** categories, then eOperator==0.  The WhereTerm.pExpr field is still set
** to the original subexpression content and wtFlags is set up appropriately
** but no other fields in the WhereTerm object are meaningful.
**
** When eOperator!=0, prereqRight and prereqAll record sets of cursor numbers,
** but they do so indirectly.  A single WhereMaskSet structure translates
** cursor number into bits and the translated bit is stored in the prereq
** fields.  The translation is used in order to maximize the number of
** bits that will fit in a Bitmask.  The VDBE cursor numbers might be
** spread out over the non-negative integers.  For example, the cursor
** numbers might be 3, 8, 9, 10, 20, 23, 41, and 45.  The WhereMaskSet
** translates these sparse cursor numbers into consecutive integers
** beginning with 0 in order to make the best possible use of the available
** bits in the Bitmask.  So, in the example above, the cursor numbers
** would be mapped into integers 0 through 7.
**
** The number of terms in a join is limited by the number of bits
** in prereqRight and prereqAll.  The default is 64 bits, hence SQLite
** is only able to process joins with 64 or fewer tables.

//	** Cursor iCur is open on an intkey b-tree (a table). Register iRowid contains

//	** function generates code to do a deferred seek of cursor iCur to the
//	** rowid stored in register iRowid.
//	**
//	** Normally, this is just:
//	**
//	**   OP_DeferredSeek $iCur $iRowid
//	**
//	** Which causes a seek on $iCur to the row with rowid $iRowid.
//	**
//	** However, if the scan currently being coded is a branch of an OR-loop and

//	** is added that might allow OP_Column to omit the seek and instead do its
//	** lookup on the index, thus avoiding an expensive seek operation.  To
//	** enable this optimization, the P3 of OP_DeferredSeek is set to iIdxCur
//	** and P4 is set to an array of integers containing one entry for each column
//	** in the table.  For each table column, if the column is the i'th
//	** column of the index, then the corresponding array entry is set to (i+1).
//	** If the column does not appear in the index at all, the array entry is set

//	** Analyze a term that consists of two or more OR-connected
//	** subterms.  So in:
//	**
//	**     ... WHERE  (a=5) AND (b=7 OR c=9 OR d=13) AND (d=13)
//	**                          ^^^^^^^^^^^^^^^^^^^^
//	**
//	** This routine analyzes terms such as the middle term in the above example.
//	** A WhereOrTerm object is computed and attached to the term under
//	** analysis, regardless of the outcome of the analysis.  Hence:
//	**
//	**     WhereTerm.wtFlags   |=  TERM_ORINFO
//	**     WhereTerm.u.pOrInfo  =  a dynamically allocated WhereOrTerm object
//	**
//	** The term being analyzed must have two or more of OR-connected subterms.
//	** A single subterm might be a set of AND-connected sub-subterms.
//	** Examples of terms under analysis:
//	**
//	**     (A)     t1.x=t2.y OR t1.x=t2.z OR t1.y=15 OR t1.z=t3.a+5
//	**     (B)     x=expr1 OR expr2=x OR x=expr3
//	**     (C)     t1.x=t2.y OR (t1.x=t2.z AND t1.y=15)
//	**     (D)     x=expr1 OR (y>11 AND y<22 AND z LIKE '*hello*')
//	**     (E)     (p.a=1 AND q.b=2 AND r.c=3) OR (p.x=4 AND q.y=5 AND r.z=6)
//	**     (F)     x>A OR (x=A AND y>=B)
//	**
//	** CASE 1:
//	**
//	** If all subterms are of the form T.C=expr for some single column of C and
//	** a single table T (as shown in example B above) then create a new virtual
//	** term that is an equivalent IN expression.  In other words, if the term
//	** being analyzed is:
//	**
//	**      x = expr1  OR  expr2 = x  OR  x = expr3
//	**
//	** then create a new virtual term like this:
//	**
//	**      x IN (expr1,expr2,expr3)
//	**
//	** CASE 2:
//	**
//	** If there are exactly two disjuncts and one side has x>A and the other side
//	** has x=A (for the same x and A) then add a new virtual conjunct term to the
//	** WHERE clause of the form "x>=A".  Example:
//	**
//	**      x>A OR (x=A AND y>B)    adds:    x>=A
//	**
//	** The added conjunct can sometimes be helpful in query planning.
//	**
//	** CASE 3:
//	**
//	** If all subterms are indexable by a single table T, then set
//	**
//	**     WhereTerm.eOperator              =  WO_OR
//	**     WhereTerm.u.pOrInfo->indexable  |=  the cursor number for table T
//	**
//	** A subterm is "indexable" if it is of the form
//	** "T.C <op> <expr>" where C is any column of table T and
//	** <op> is one of "=", "<", "<=", ">", ">=", "IS NULL", or "IN".
//	** A subterm is also indexable if it is an AND of two or more
//	** subsubterms at least one of which is indexable.  Indexable AND
//	** subterms have their eOperator set to WO_AND and they have
//	** u.pAndInfo set to a dynamically allocated WhereAndTerm object.
//	**
//	** From another point of view, "indexable" means that the subterm could
//	** potentially be used with an index if an appropriate index exists.
//	** This analysis does not consider whether or not the index exists; that
//	** is decided elsewhere.  This analysis only looks at whether subterms
//	** appropriate for indexing exist.
//	**
//	** All examples A through E above satisfy case 3.  But if a term
//	** also satisfies case 1 (such as B) we know that the optimizer will
//	** always prefer case 1, so in that case we pretend that case 3 is not
//	** satisfied.
//	**
//	** It might be the case that multiple tables are indexable.  For example,
//	** (E) above is indexable on tables P, Q, and R.
//	**
//	** Terms that satisfy case 3 are candidates for lookup by using
//	** separate indices to find rowids for each subterm and composing
//	** the union of all rowids using a RowSet object.  This is similar
//	** to "bitmap indices" in other database engines.
//	**
//	** OTHERWISE:
//	**
//	** If none of cases 1, 2, or 3 apply, then leave the eOperator set to
//	** zero.  This term is not useful for search.

//	** For a full scan, assuming the table (or index) contains nRow rows:

//	**     cost = nRow * (K+3.0)                // scan of non-covering index
//	**
//	** where K is a value between 1.1 and 3.0 set based on the relative
//	** estimated average size of the index and table records.
//	**
//	** For an index scan, where nVisit is the number of index rows visited

//	** the index b-tree:
//	**
//	**     cost = nSeek * (log(nRow) + K * nVisit)          // covering index
//	**     cost = nSeek * (log(nRow) + (K+3.0) * nVisit)    // non-covering index

//	** Normally, nSeek is 1. nSeek values greater than 1 come about if the
//	** WHERE clause includes "x IN (....)" terms used in place of "x=?". Or when
//	** implicit "x IN (SELECT x FROM tbl)" terms are added for skip-scans.
//	**
//	** The estimated values (nRow, nVisit, nSeek) often contain a large amount
//	** of uncertainty.  For this reason, scoring is designed to pick plans that
//	** "do the least harm" if the estimates are inaccurate.  For example, a

//	** Generate the beginning of the loop used for WHERE clause processing.
//	** The return value is a pointer to an opaque structure that contains
//	** information needed to terminate the loop.  Later, the calling routine
//	** should invoke sqlite3WhereEnd() with the return value of this function
//	** in order to complete the WHERE clause processing.
//	**
//	** If an error occurs, this routine returns NULL.
//	**
//	** The basic idea is to do a nested loop, one loop for each table in
//	** the FROM clause of a select.  (INSERT and UPDATE statements are the
//	** same as a SELECT with only a single table in the FROM clause.)  For
//	** example, if the SQL is this:
//	**
//	**       SELECT * FROM t1, t2, t3 WHERE ...;
//	**
//	** Then the code generated is conceptually like the following:
//	**
//	**      foreach row1 in t1 do       \    Code generated
//	**        foreach row2 in t2 do      |-- by sqlite3WhereBegin()
//	**          foreach row3 in t3 do   /
//	**            ...
//	**          end                     \    Code generated
//	**        end                        |-- by sqlite3WhereEnd()
//	**      end                         /
//	**
//	** Note that the loops might not be nested in the order in which they
//	** appear in the FROM clause if a different order is better able to make
//	** use of indices.  Note also that when the IN operator appears in
//	** the WHERE clause, it might result in additional nested loops for
//	** scanning through all values on the right-hand side of the IN.
//	**
//	** There are Btree cursors associated with each table.  t1 uses cursor
//	** number pTabList->a[0].iCursor.  t2 uses the cursor pTabList->a[1].iCursor.
//	** And so forth.  This routine generates code to open those VDBE cursors
//	** and sqlite3WhereEnd() generates the code to close them.
//	**
//	** The code that sqlite3WhereBegin() generates leaves the cursors named
//	** in pTabList pointing at their appropriate entries.  The [...] code
//	** can use OP_Column and OP_Rowid opcodes on these cursors to extract
//	** data from the various tables of the loop.
//	**
//	** If the WHERE clause is empty, the foreach loops must each scan their
//	** entire tables.  Thus a three-way join is an O(N^3) operation.  But if
//	** the tables have indices and there are terms in the WHERE clause that
//	** refer to those indices, a complete table scan can be avoided and the
//	** code will run much faster.  Most of the work of this routine is checking
//	** to see if there are indices that can be used to speed up the loop.
//	**
//	** Terms of the WHERE clause are also used to limit which rows actually
//	** make it to the "..." in the middle of the loop.  After each "foreach",
//	** terms of the WHERE clause that use only terms in that loop and outer
//	** loops are evaluated and if false a jump is made around all subsequent
//	** inner loops (or around the "..." if the test occurs within the inner-
//	** most loop)
//	**
//	** OUTER JOINS
//	**
//	** An outer join of tables t1 and t2 is conceptually coded as follows:
//	**
//	**    foreach row1 in t1 do
//	**      flag = 0
//	**      foreach row2 in t2 do
//	**        start:
//	**          ...
//	**          flag = 1
//	**      end
//	**      if flag==0 then
//	**        move the row2 cursor to a null row
//	**        goto start
//	**      fi
//	**    end
//	**
//	** ORDER BY CLAUSE PROCESSING
//	**
//	** pOrderBy is a pointer to the ORDER BY clause (or the GROUP BY clause
//	** if the WHERE_GROUPBY flag is set in wctrlFlags) of a SELECT statement
//	** if there is one.  If there is no ORDER BY clause or if this routine
//	** is called from an UPDATE or DELETE statement, then pOrderBy is NULL.
//	**
//	** The iIdxCur parameter is the cursor number of an index.  If
//	** WHERE_OR_SUBCLAUSE is set, iIdxCur is the cursor number of an index
//	** to use for OR clause processing.  The WHERE clause should use this
//	** specific cursor.  If WHERE_ONEPASS_DESIRED is set, then iIdxCur is
//	** the first cursor in an array of cursors for all indices.  iIdxCur should
//	** be used to compute the appropriate cursor depending on which index is
//	** used.

/*
** SELECT REWRITING
**
**   Any SELECT statement that contains one or more window functions in
**   either the select list or ORDER BY clause (the only two places window
**   functions may be used) is transformed by function sqlite3WindowRewrite()
**   in order to support window function processing. For example, with the
**   schema:
**
**     CREATE TABLE t1(a, b, c, d, e, f, g);
**
**   the statement:
**
**     SELECT a+1, max(b) OVER (PARTITION BY c ORDER BY d) FROM t1 ORDER BY e;
**
**   is transformed to:
**
**     SELECT a+1, max(b) OVER (PARTITION BY c ORDER BY d) FROM (
**         SELECT a, e, c, d, b FROM t1 ORDER BY c, d
**     ) ORDER BY e;
**
**   The flattening optimization is disabled when processing this transformed
**   SELECT statement. This allows the implementation of the window function
**   (in this case max()) to process rows sorted in order of (c, d), which
**   makes things easier for obvious reasons. More generally:
**
**     * FROM, WHERE, GROUP BY and HAVING clauses are all moved to
**       the sub-query.
**
**     * ORDER BY, LIMIT and OFFSET remain part of the parent query.
**
**     * Terminals from each of the expression trees that make up the
**       select-list and ORDER BY expressions in the parent query are
**       selected by the sub-query. For the purposes of the transformation,
**       terminals are column references and aggregate functions.
**
**   If there is more than one window function in the SELECT that uses
**   the same window declaration (the OVER bit), then a single scan may
**   be used to process more than one window function. For example:
**
**     SELECT max(b) OVER (PARTITION BY c ORDER BY d),
**            min(e) OVER (PARTITION BY c ORDER BY d)
**     FROM t1;
**
**   is transformed in the same way as the example above. However:
**
**     SELECT max(b) OVER (PARTITION BY c ORDER BY d),
**            min(e) OVER (PARTITION BY a ORDER BY b)
**     FROM t1;
**
**   Must be transformed to:
**
**     SELECT max(b) OVER (PARTITION BY c ORDER BY d) FROM (
**         SELECT e, min(e) OVER (PARTITION BY a ORDER BY b), c, d, b FROM
**           SELECT a, e, c, d, b FROM t1 ORDER BY a, b
**         ) ORDER BY c, d
**     ) ORDER BY e;
**
**   so that both min() and max() may process rows in the order defined by
**   their respective window declarations.
**
** INTERFACE WITH SELECT.C
**
**   When processing the rewritten SELECT statement, code in select.c calls
**   sqlite3WhereBegin() to begin iterating through the results of the
**   sub-query, which is always implemented as a co-routine. It then calls
**   sqlite3WindowCodeStep() to process rows and finish the scan by calling
**   sqlite3WhereEnd().
**
**   sqlite3WindowCodeStep() generates VM code so that, for each row returned
**   by the sub-query a sub-routine (OP_Gosub) coded by select.c is invoked.
**   When the sub-routine is invoked:
**
**     * The results of all window-functions for the row are stored
**       in the associated Window.regResult registers.
**
**     * The required terminal values are stored in the current row of
**       temp table Window.iEphCsr.
**
**   In some cases, depending on the window frame and the specific window
**   functions invoked, sqlite3WindowCodeStep() caches each entire partition
**   in a temp table before returning any rows. In other cases it does not.
**   This detail is encapsulated within this file, the code generated by
**   select.c is the same in either case.
**
** BUILT-IN WINDOW FUNCTIONS
**
**   This implementation features the following built-in window functions:
**
**     row_number()
**     rank()
**     dense_rank()
**     percent_rank()
**     cume_dist()
**     ntile(N)
**     lead(expr [, offset [, default]])
**     lag(expr [, offset [, default]])
**     first_value(expr)
**     last_value(expr)
**     nth_value(expr, N)
**
**   These are the same built-in window functions supported by Postgres.
**   Although the behaviour of aggregate window functions (functions that
**   can be used as either aggregates or window functions) allows them to
**   be implemented using an API, built-in window functions are much more
**   esoteric. Additionally, some window functions (e.g. nth_value())
**   may only be implemented by caching the entire partition in memory.
**   As such, some built-in window functions use the same API as aggregate
**   window functions and some are implemented directly using VDBE
**   instructions. Additionally, for those functions that use the API, the
**   window frame is sometimes modified before the SELECT statement is
**   rewritten. For example, regardless of the specified window frame, the
**   row_number() function always uses:
**
**     ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW
**
**   See sqlite3WindowUpdate() for details.
**
**   As well as some of the built-in window functions, aggregate window
**   functions min() and max() are implemented using VDBE instructions if
**   the start of the window frame is declared as anything other than
**   UNBOUNDED PRECEDING.

** A single instance of this structure is allocated on the stack by
** sqlite3WindowCodeStep() and a pointer to it passed to the various helper
** routines. This is to reduce the number of arguments required by each
** helper function.
**
** regArg:
**   Each window function requires an accumulator register (just as an
**   ordinary aggregate function does). This variable is set to the first
**   in an array of accumulator registers - one for each window function
**   in the WindowCodeArg.pMWin list.
**
** eDelete:
**   The window functions implementation sometimes caches the input rows
**   that it processes in a temporary table. If it is not zero, this
**   variable indicates when rows may be removed from the temp table (in
**   order to reduce memory requirements - it would always be safe just
**   to leave them there). Possible values for eDelete are:
**
**      WINDOW_RETURN_ROW:
**        An input row can be discarded after it is returned to the caller.
**
**      WINDOW_AGGINVERSE:
**        An input row can be discarded after the window functions xInverse()
**        callbacks have been invoked in it.
**
**      WINDOW_AGGSTEP:
**        An input row can be discarded after the window functions xStep()
**        callbacks have been invoked in it.
**
** start,current,end
**   Consider a window-frame similar to the following:
**
**     (ORDER BY a, b GROUPS BETWEEN 2 PRECEDING AND 2 FOLLOWING)
**
**   The windows functions implementation caches the input rows in a temp
**   table, sorted by "a, b" (it actually populates the cache lazily, and
**   aggressively removes rows once they are no longer required, but that's
**   a mere detail). It keeps three cursors open on the temp table. One
**   (current) that points to the next row to return to the query engine
**   once its window function values have been calculated. Another (end)
**   points to the next row to call the xStep() method of each window function
**   on (so that it is 2 groups ahead of current). And a third (start) that
**   points to the next row to call the xInverse() method of each window
**   function on.
**
**   Each cursor (start, current and end) consists of a VDBE cursor
**   (WindowCsrAndReg.csr) and an array of registers (starting at
**   WindowCodeArg.reg) that always contains a copy of the peer values
**   read from the corresponding cursor.
**
**   Depending on the window-frame in question, all three cursors may not
**   be required. In this case both WindowCodeArg.csr and reg are set to
**   0.

//	** The pseudo-code above uses the following shorthand:

//	**   AGGSTEP:    invoke the aggregate xStep() function for each window function
//	**               with arguments read from the current row of cursor csrEnd, then
//	**               step cursor csrEnd forward one row (i.e. sqlite3BtreeNext()).
//	**
//	**   RETURN_ROW: return a row to the caller based on the contents of the
//	**               current row of csrCurrent and the current state of all
//	**               aggregates. Then step cursor csrCurrent forward one row.
//	**
//	**   AGGINVERSE: invoke the aggregate xInverse() function for each window
//	**               functions with arguments read from the current row of cursor
//	**               csrStart. Then step csrStart forward one row.
//	**
//	** There are two other ROWS window frames that are handled significantly
//	** differently from the above - "BETWEEN <expr> PRECEDING AND <expr> PRECEDING"
//	** and "BETWEEN <expr> FOLLOWING AND <expr> FOLLOWING". These are special
//	** cases because they change the order in which the three cursors (csrStart,
//	** csrCurrent and csrEnd) iterate through the ephemeral table. Cases that

//	** For the most part, the patterns above are adapted to support UNBOUNDED by

//	** This is optimized of course - branches that will never be taken and
//	** conditions that are always true are omitted from the VM code. The only
//	** exceptional case is:
//	**
//	**   ROWS BETWEEN <expr1> FOLLOWING AND UNBOUNDED FOLLOWING
//	**
//	**     ... loop started by sqlite3WhereBegin() ...

//	**     }
//	**     while( !eof csrCurrent ){
//	**       RETURN_ROW
//	**     }
//	**
//	** Also requiring special handling are the cases:
//	**
//	**   ROWS BETWEEN <expr1> PRECEDING AND <expr2> PRECEDING
//	**   ROWS BETWEEN <expr1> FOLLOWING AND <expr2> FOLLOWING
//	**
//	** when (expr1 < expr2). This is detected at runtime, not by this function.
//	** To handle this case, the pseudo-code programs depicted above are modified
//	** slightly to be:
//	**
//	**     ... loop started by sqlite3WhereBegin() ...
//	**     if( new partition ){
//	**       Gosub flush
//	**     }
//	**     Insert new row into eph table.
//	**     if( first row of partition ){
//	**       Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent)
//	**       regEnd = <expr2>
//	**       regStart = <expr1>
//	**       if( regEnd < regStart ){
//	**         RETURN_ROW
//	**         delete eph table contents
//	**         continue
//	**       }
//	**     ...
//	**
//	** The new "continue" statement in the above jumps to the next iteration
//	** of the outer loop - the one started by sqlite3WhereBegin().
//	**
//	** The various GROUPS cases are implemented using the same patterns as
//	** ROWS. The VM code is modified slightly so that:
//	**
//	**   1. The else branch in the main loop is only taken if the row just
//	**      added to the ephemeral table is the start of a new group. In
//	**      other words, it becomes:
//	**
//	**         ... loop started by sqlite3WhereBegin() ...
//	**         if( new partition ){
//	**           Gosub flush
//	**         }
//	**         Insert new row into eph table.
//	**         if( first row of partition ){
//	**           Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent)
//	**           regEnd = <expr2>
//	**           regStart = <expr1>
//	**         }else if( new group ){
//	**           ...
//	**         }
//	**       }
//	**
//	**   2. Instead of processing a single row, each RETURN_ROW, AGGSTEP or
//	**      AGGINVERSE step processes the current row of the relevant cursor and
//	**      all subsequent rows belonging to the same group.
//	**
//	** RANGE window frames are a little different again. As for GROUPS, the
//	** main loop runs once per group only. And RETURN_ROW, AGGSTEP and AGGINVERSE
//	** deal in groups instead of rows. As for ROWS and GROUPS, there are three
//	** basic cases:
//	**
//	**   RANGE BETWEEN <expr1> PRECEDING AND <expr2> FOLLOWING
//	**
//	**     ... loop started by sqlite3WhereBegin() ...
//	**       if( new partition ){
//	**         Gosub flush
//	**       }
//	**       Insert new row into eph table.
//	**       if( first row of partition ){
//	**         Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent)
//	**         regEnd = <expr2>
//	**         regStart = <expr1>

//	**    YYCODETYPE         is the data type used to store the integer codes
//	**                       that represent terminal and non-terminal symbols.
//	**                       "unsigned char" is used if there are fewer than
//	**                       256 symbols.  Larger types otherwise.
//	**    YYNOCODE           is a number of type YYCODETYPE that is not used for
//	**                       any terminal or nonterminal symbol.
//	**    YYFALLBACK         If defined, this indicates that one or more tokens
//	**                       (also known as: "terminal symbols") have fall-back
//	**                       values which should be used if the original symbol
//	**                       would not parse.  This permits keywords to sometimes
//	**                       be used as identifiers, for example.
//	**    YYACTIONTYPE       is the data type used for "action codes" - numbers
//	**                       that indicate what to do in response to the next
//	**                       token.
//	**    sqlite3ParserTOKENTYPE     is the data type used for minor type for terminal
//	**                       symbols.  Background: A "minor type" is a semantic
//	**                       value associated with a terminal or non-terminal
//	**                       symbols.  For example, for an "ID" terminal symbol,
//	**                       the minor type might be the name of the identifier.
//	**                       Each non-terminal can have a different minor type.
//	**                       Terminal symbols all have the same minor type, though.
//	**                       This macros defines the minor type for terminal
//	**                       symbols.
//	**    YYMINORTYPE        is the data type used for all minor types.
//	**                       This is typically a union of many types, one of
//	**                       which is sqlite3ParserTOKENTYPE.  The entry in the union
//	**                       for terminal symbols is called "yy0".
//	**    YYSTACKDEPTH       is the maximum depth of the parser's stack.  If
//	**                       zero the stack is dynamically sized using realloc()
//	**    sqlite3ParserARG_SDECL     A static variable declaration for the %extra_argument
//	**    sqlite3ParserARG_PDECL     A parameter declaration for the %extra_argument
//	**    sqlite3ParserARG_PARAM     Code to pass %extra_argument as a subroutine parameter
//	**    sqlite3ParserARG_STORE     Code to store %extra_argument into yypParser
//	**    sqlite3ParserARG_FETCH     Code to extract %extra_argument from yypParser
//	**    sqlite3ParserCTX_*         As sqlite3ParserARG_ except for %extra_context
//	**    YYERRORSYMBOL      is the code number of the error symbol.  If not
//	**                       defined, then do no error processing.
//	**    YYNSTATE           the combined number of states.
//	**    YYNRULE            the number of rules in the grammar
//	**    YYNTOKEN           Number of terminal symbols

//	** Suppose the action integer is N.  Then the action is determined as

//	**     and YY_MAX_REDUCE
//	**
//	** The action table is constructed as a single large table named yy_action[].
//	** Given state S and lookahead X, the action is computed as either:
//	**
//	**    (A)   N = yy_action[ yy_shift_ofst[S] + X ]
//	**    (B)   N = yy_default[S]
//	**
//	** The (A) formula is preferred.  The B formula is used instead if
//	** yy_lookahead[yy_shift_ofst[S]+X] is not equal to X.
//	**
//	** The formulas above are for computing the action when the lookahead is
//	** a terminal symbol.  If the lookahead is a non-terminal (as occurs after
//	** a reduce action) then the yy_reduce_ofst[] array is used in place of
//	** the yy_shift_ofst[] array.
//	**
//	** The following are the tables generated in this section:
//	**
//	**  yy_action[]        A single table containing all actions.
//	**  yy_lookahead[]     A table containing the lookahead for each entry in
//	**                     yy_action.  Used to detect hash collisions.
//	**  yy_shift_ofst[]    For each state, the offset into yy_action for

//	** Special handling is require for CREATE TRIGGER statements.
//	** Whenever the CREATE TRIGGER keywords are seen, the statement
//	** must end with ";END;".

//	** This implementation uses a state machine with 8 states:
//	**
//	**   (0) INVALID   We have not yet seen a non-whitespace character.
//	**
//	**   (1) START     At the beginning or end of an SQL statement.  This routine
//	**                 returns 1 if it ends in the START state and 0 if it ends
//	**                 in any other state.
//	**
//	**   (2) NORMAL    We are in the middle of statement which ends with a single
//	**                 semicolon.
//	**
//	**   (3) EXPLAIN   The keyword EXPLAIN has been seen at the beginning of
//	**                 a statement.
//	**
//	**   (4) CREATE    The keyword CREATE has been seen at the beginning of a
//	**                 statement, possibly preceded by EXPLAIN and/or followed by
//	**                 TEMP or TEMPORARY
//	**
//	**   (5) TRIGGER   We are in the middle of a trigger definition that must be
//	**                 ended by a semicolon, the keyword END, and another semicolon.
//	**
//	**   (6) SEMI      We've seen the first semicolon in the ";END;" that occurs at
//	**                 the end of a trigger definition.
//	**
//	**   (7) END       We've seen the ";END" of the ";END;" that occurs at the end
//	**                 of a trigger definition.
//	**
//	** Transitions between states above are determined by tokens extracted
//	** from the input.  The following tokens are significant:
//	**
//	**   (0) tkSEMI      A semicolon.
//	**   (1) tkWS        Whitespace.
//	**   (2) tkOTHER     Any other SQL token.
//	**   (3) tkEXPLAIN   The "explain" keyword.
//	**   (4) tkCREATE    The "create" keyword.
//	**   (5) tkTEMP      The "temp" or "temporary" keyword.
//	**   (6) tkTRIGGER   The "trigger" keyword.
//	**   (7) tkEND       The "end" keyword.
//	**
//	** Whitespace never causes a state transition and is always ignored.
//	** This means that a SQL string of all whitespace is invalid.
//	**
//	** If we compile with SQLITE_OMIT_TRIGGER, all of the computation needed
//	** to recognize the end of a trigger can be omitted.  All we have to do
//	** is look for a semicolon that is not part of an string or comment.

/* The full-text index is stored in a series of b+tree (-like)

** are built from the bottom up, things will be described from the
** bottom up.
**
**
**** Varints ****
** The basic unit of encoding is a variable-length integer called a
** varint.  We encode variable-length integers in little-endian order
** using seven bits * per byte as follows:
**
** KEY:
**         A = 0xxxxxxx    7 bits of data and one flag bit
**         B = 1xxxxxxx    7 bits of data and one flag bit
**
**  7 bits - A
** 14 bits - BA
** 21 bits - BBA
** and so on.
**
** This is similar in concept to how sqlite encodes "varints" but
** the encoding is not the same.  SQLite varints are big-endian
** are are limited to 9 bytes in length whereas FTS3 varints are
** little-endian and can be up to 10 bytes in length (in theory).
**
** Example encodings:
**
**     1:    0x01
**   127:    0x7f
**   128:    0x81 0x00
**
**
**** Document lists ****
** A doclist (document list) holds a docid-sorted list of hits for a
** given term.  Doclists hold docids and associated token positions.
** A docid is the unique integer identifier for a single document.
** A position is the index of a word within the document.  The first
** word of the document has a position of 0.
**
** FTS3 used to optionally store character offsets using a compile-time
** option.  But that functionality is no longer supported.
**
** A doclist is stored like this:
**
** array {
**   varint docid;          (delta from previous doclist)
**   array {                (position list for column 0)
**     varint position;     (2 more than the delta from previous position)
**   }
**   array {
**     varint POS_COLUMN;   (marks start of position list for new column)
**     varint column;       (index of new column)
**     array {
**       varint position;   (2 more than the delta from previous position)
**     }
**   }
**   varint POS_END;        (marks end of positions for this document.
** }
**
** Here, array { X } means zero or more occurrences of X, adjacent in
** memory.  A "position" is an index of a token in the token stream
** generated by the tokenizer. Note that POS_END and POS_COLUMN occur
** in the same logical place as the position element, and act as sentinals
** ending a position list array.  POS_END is 0.  POS_COLUMN is 1.
** The positions numbers are not stored literally but rather as two more
** than the difference from the prior position, or the just the position plus
** 2 for the first position.  Example:
**
**   label:       A B C D E  F  G H   I  J K
**   value:     123 5 9 1 1 14 35 0 234 72 0
**
** The 123 value is the first docid.  For column zero in this document
** there are two matches at positions 3 and 10 (5-2 and 9-2+3).  The 1
** at D signals the start of a new column; the 1 at E indicates that the
** new column is column number 1.  There are two positions at 12 and 45
** (14-2 and 35-2+12).  The 0 at H indicate the end-of-document.  The
** 234 at I is the delta to next docid (357).  It has one position 70
** (72-2) and then terminates with the 0 at K.
**
** A "position-list" is the list of positions for multiple columns for
** a single docid.  A "column-list" is the set of positions for a single
** column.  Hence, a position-list consists of one or more column-lists,
** a document record consists of a docid followed by a position-list and
** a doclist consists of one or more document records.
**
** A bare doclist omits the position information, becoming an
** array of varint-encoded docids.
**
**** Segment leaf nodes ****
** Segment leaf nodes store terms and doclists, ordered by term.  Leaf
** nodes are written using LeafWriter, and read using LeafReader (to
** iterate through a single leaf node's data) and LeavesReader (to
** iterate through a segment's entire leaf layer).  Leaf nodes have
** the format:
**
** varint iHeight;             (height from leaf level, always 0)
** varint nTerm;               (length of first term)
** char pTerm[nTerm];          (content of first term)
** varint nDoclist;            (length of term's associated doclist)
** char pDoclist[nDoclist];    (content of doclist)
** array {
**                             (further terms are delta-encoded)
**   varint nPrefix;           (length of prefix shared with previous term)
**   varint nSuffix;           (length of unshared suffix)
**   char pTermSuffix[nSuffix];(unshared suffix of next term)
**   varint nDoclist;          (length of term's associated doclist)
**   char pDoclist[nDoclist];  (content of doclist)
** }
**
** Here, array { X } means zero or more occurrences of X, adjacent in
** memory.
**
** Leaf nodes are broken into blocks which are stored contiguously in
** the %_segments table in sorted order.  This means that when the end
** of a node is reached, the next term is in the node with the next
** greater node id.
**
** New data is spilled to a new leaf node when the current node
** exceeds LEAF_MAX bytes (default 2048).  New data which itself is
** larger than STANDALONE_MIN (default 1024) is placed in a standalone
** node (a leaf node with a single term and doclist).  The goal of
** these settings is to pack together groups of small doclists while
** making it efficient to directly access large doclists.  The
** assumption is that large doclists represent terms which are more
** likely to be query targets.
**
** TODO(shess) It may be useful for blocking decisions to be more
** dynamic.  For instance, it may make more sense to have a 2.5k leaf
** node rather than splitting into 2k and .5k nodes.  My intuition is
** that this might extend through 2x or 4x the pagesize.
**
**
**** Segment interior nodes ****
** Segment interior nodes store blockids for subtree nodes and terms
** to describe what data is stored by the each subtree.  Interior
** nodes are written using InteriorWriter, and read using
** InteriorReader.  InteriorWriters are created as needed when
** SegmentWriter creates new leaf nodes, or when an interior node
** itself grows too big and must be split.  The format of interior
** nodes:
**
** varint iHeight;           (height from leaf level, always >0)
** varint iBlockid;          (block id of node's leftmost subtree)
** optional {
**   varint nTerm;           (length of first term)
**   char pTerm[nTerm];      (content of first term)
**   array {
**                                (further terms are delta-encoded)
**     varint nPrefix;            (length of shared prefix with previous term)
**     varint nSuffix;            (length of unshared suffix)
**     char pTermSuffix[nSuffix]; (unshared suffix of next term)
**   }
** }
**
** Here, optional { X } means an optional element, while array { X }
** means zero or more occurrences of X, adjacent in memory.
**
** An interior node encodes n terms separating n+1 subtrees.  The
** subtree blocks are contiguous, so only the first subtree's blockid
** is encoded.  The subtree at iBlockid will contain all terms less
** than the first term encoded (or all terms if no term is encoded).
** Otherwise, for terms greater than or equal to pTerm[i] but less
** than pTerm[i+1], the subtree for that term will be rooted at
** iBlockid+i.  Interior nodes only store enough term data to
** distinguish adjacent children (if the rightmost term of the left
** child is "something", and the leftmost term of the right child is
** "wicked", only "w" is stored).
**
** New data is spilled to a new interior node at the same height when
** the current node exceeds INTERIOR_MAX bytes (default 2048).
** INTERIOR_MIN_TERMS (default 7) keeps large terms from monopolizing
** interior nodes and making the tree too skinny.  The interior nodes
** at a given height are naturally tracked by interior nodes at
** height+1, and so on.
**
**
**** Segment directory ****
** The segment directory in table %_segdir stores meta-information for
** merging and deleting segments, and also the root node of the
** segment's tree.
**
** The root node is the top node of the segment's tree after encoding
** the entire segment, restricted to ROOT_MAX bytes (default 1024).
** This could be either a leaf node or an interior node.  If the top
** node requires more than ROOT_MAX bytes, it is flushed to %_segments
** and a new root interior node is generated (which should always fit
** within ROOT_MAX because it only needs space for 2 varints, the
** height and the blockid of the previous root).
**
** The meta-information in the segment directory is:
**   level               - segment level (see below)
**   idx                 - index within level
**                       - (level,idx uniquely identify a segment)
**   start_block         - first leaf node
**   leaves_end_block    - last leaf node
**   end_block           - last block (including interior nodes)
**   root                - contents of root node
**
** If the root node is a leaf node, then start_block,
** leaves_end_block, and end_block are all 0.
**
**
**** Segment merging ****
** To amortize update costs, segments are grouped into levels and
** merged in batches.  Each increase in level represents exponentially
** more documents.
**
** New documents (actually, document updates) are tokenized and
** written individually (using LeafWriter) to a level 0 segment, with
** incrementing idx.  When idx reaches MERGE_COUNT (default 16), all
** level 0 segments are merged into a single level 1 segment.  Level 1
** is populated like level 0, and eventually MERGE_COUNT level 1
** segments are merged to a single level 2 segment (representing
** MERGE_COUNT^2 updates), and so on.
**
** A segment merge traverses all segments at a given level in
** parallel, performing a straightforward sorted merge.  Since segment
** leaf nodes are written in to the %_segments table in order, this
** merge traverses the underlying sqlite disk structures efficiently.
** After the merge, all segment blocks from the merged level are
** deleted.
**
** MERGE_COUNT controls how often we merge segments.  16 seems to be
** somewhat of a sweet spot for insertion performance.  32 and 64 show
** very similar performance numbers to 16 on insertion, though they're
** a tiny bit slower (perhaps due to more overhead in merge-time
** sorting).  8 is about 20% slower than 16, 4 about 50% slower than
** 16, 2 about 66% slower than 16.
**
** At query time, high MERGE_COUNT increases the number of segments
** which need to be scanned and merged.  For instance, with 100k docs
** inserted:
**
**    MERGE_COUNT   segments
**       16           25
**        8           12
**        4           10
**        2            6
**
** This appears to have only a moderate impact on queries for very
** frequent terms (which are somewhat dominated by segment merge
** costs), and infrequent and non-existent terms still seem to be fast
** even with many segments.
**
** TODO(shess) That said, it would be nice to have a better query-side
** argument for MERGE_COUNT of 16.  Also, it is possible/likely that
** optimizations to things like doclist merging will swing the sweet
** spot around.
**
**
**
**** Handling of deletions and updates ****
** Since we're using a segmented structure, with no docid-oriented
** index into the term index, we clearly cannot simply update the term
** index when a document is deleted or updated.  For deletions, we
** write an empty doclist (varint(docid) varint(POS_END)), for updates
** we simply write the new doclist.  Segment merges overwrite older
** data for a particular docid with newer data, so deletes or updates
** will eventually overtake the earlier data and knock it out.  The
** query logic likewise merges doclists so that newer data knocks out
** older data.

******************************************************************************
**
** SQLite JSON functions.
**
** This file began as an extension in ext/misc/json1.c in 2015.  That
** extension proved so useful that it has now been moved into the core.
**
** The original design stored all JSON as pure text, canonical RFC-8259.
** Support for JSON-5 extensions was added with version 3.42.0 (2023-05-16).
** All generated JSON text still conforms strictly to RFC-8259, but text
** with JSON-5 extensions is accepted as input.
**
** Beginning with version 3.45.0 (circa 2024-01-01), these routines also
** accept BLOB values that have JSON encoded using a binary representation
** called "JSONB".  The name JSONB comes from PostgreSQL, however the on-disk
** format SQLite JSONB is completely different and incompatible with
** PostgreSQL JSONB.
**
** Decoding and interpreting JSONB is still O(N) where N is the size of
** the input, the same as text JSON.  However, the constant of proportionality
** for JSONB is much smaller due to faster parsing.  The size of each
** element in JSONB is encoded in its header, so there is no need to search
** for delimiters using persnickety syntax rules.  JSONB seems to be about
** 3x faster than text JSON as a result.  JSONB is also tends to be slightly
** smaller than text JSON, by 5% or 10%, but there are corner cases where
** JSONB can be slightly larger.  So you are not far mistaken to say that
** a JSONB blob is the same size as the equivalent RFC-8259 text.
**
**
** THE JSONB ENCODING:
**
** Every JSON element is encoded in JSONB as a header and a payload.
** The header is between 1 and 9 bytes in size.  The payload is zero
** or more bytes.
**
** The lower 4 bits of the first byte of the header determines the
** element type:
**
**    0:   NULL
**    1:   TRUE
**    2:   FALSE
**    3:   INT        -- RFC-8259 integer literal
**    4:   INT5       -- JSON5 integer literal
**    5:   FLOAT      -- RFC-8259 floating point literal
**    6:   FLOAT5     -- JSON5 floating point literal
**    7:   TEXT       -- Text literal acceptable to both SQL and JSON
**    8:   TEXTJ      -- Text containing RFC-8259 escapes
**    9:   TEXT5      -- Text containing JSON5 and/or RFC-8259 escapes
**   10:   TEXTRAW    -- Text containing unescaped syntax characters
**   11:   ARRAY
**   12:   OBJECT
**
** The other three possible values (13-15) are reserved for future
** enhancements.
**
** The upper 4 bits of the first byte determine the size of the header
** and sometimes also the size of the payload.  If X is the first byte
** of the element and if X>>4 is between 0 and 11, then the payload
** will be that many bytes in size and the header is exactly one byte
** in size.  Other four values for X>>4 (12-15) indicate that the header
** is more than one byte in size and that the payload size is determined
** by the remainder of the header, interpreted as a unsigned big-endian
** integer.
**
**   Value of X>>4         Size integer        Total header size
**   -------------     --------------------    -----------------
**        12           1 byte (0-255)                2
**        13           2 byte (0-65535)              3
**        14           4 byte (0-4294967295)         5
**        15           8 byte (0-1.8e19)             9
**
** The payload size need not be expressed in its minimal form.  For example,
** if the payload size is 10, the size can be expressed in any of 5 different
** ways: (1) (X>>4)==10, (2) (X>>4)==12 following by on 0x0a byte,
** (3) (X>>4)==13 followed by 0x00 and 0x0a, (4) (X>>4)==14 followed by
** 0x00 0x00 0x00 0x0a, or (5) (X>>4)==15 followed by 7 bytes of 0x00 and
** a single byte of 0x0a.  The shorter forms are preferred, of course, but
** sometimes when generating JSONB, the payload size is not known in advance
** and it is convenient to reserve sufficient header space to cover the
** largest possible payload size and then come back later and patch up
** the size when it becomes known, resulting in a non-minimal encoding.
**
** The value (X>>4)==15 is not actually used in the current implementation
** (as SQLite is currently unable handle BLOBs larger than about 2GB)
** but is included in the design to allow for future enhancements.
**
** The payload follows the header.  NULL, TRUE, and FALSE have no payload and
** their payload size must always be zero.  The payload for INT, INT5,
** FLOAT, FLOAT5, TEXT, TEXTJ, TEXT5, and TEXTROW is text.  Note that the
** "..." or '...' delimiters are omitted from the various text encodings.
** The payload for ARRAY and OBJECT is a list of additional elements that
** are the content for the array or object.  The payload for an OBJECT
** must be an even number of elements.  The first element of each pair is
** the label and must be of type TEXT, TEXTJ, TEXT5, or TEXTRAW.
**
** A valid JSONB blob consists of a single element, as described above.
** Usually this will be an ARRAY or OBJECT element which has many more
** elements as its content.  But the overall blob is just a single element.
**
** Input validation for JSONB blobs simply checks that the element type
** code is between 0 and 12 and that the total size of the element
** (header plus payload) is the same as the size of the BLOB.  If those
** checks are true, the BLOB is assumed to be JSONB and processing continues.
** Errors are only raised if some other miscoding is discovered during
** processing.
**
** Additional information can be found in the doc/jsonb.md file of the
** canonical SQLite source tree.

//	** pTarget is the target. pPatch is the patch.  The target is updated

//	**
//	** The original RFC-7396 algorithm is this:

//	**   define MergePatch(Target, Patch):
//	**     if Patch is an Object:
//	**       if Target is not an Object:

//	**     for each Name/Value pair in Patch:
//	**         if Value is null:
//	**           if Name exists in Target:
//	**             remove the Name/Value pair from Target
//	**         else:

//	**       return Target
//	**     else:
//	**       return Patch
//	**
//	** Here is an equivalent algorithm restructured to show the actual
//	** implementation:
//	**
//	** 01   define MergePatch(Target, Patch):
//	** 02      if Patch is not an Object:
//	** 03         return Patch
//	** 04      else: // if Patch is an Object
//	** 05         if Target is not an Object:
//	** 06            Target = {}
//	** 07      for each Name/Value pair in Patch:
//	** 08         if Name exists in Target:
//	** 09            if Value is null:
//	** 10               remove the Name/Value pair from Target
//	** 11            else
//	** 12               Target[name] = MergePatch(Target[Name], Value)

//	** 16            else:

//	** Check the JSON argument to see if it is well-formed.  The FLAGS argument
//	** encodes the various constraints on what is meant by "well-formed":
//	**
//	**     0x01      Canonical RFC-8259 JSON text
//	**     0x02      JSON text with optional JSON-5 extensions
//	**     0x04      Superficially appears to be JSONB
//	**     0x08      Strictly well-formed JSONB
//	**
//	** If the FLAGS argument is omitted, it defaults to 1.  Useful values for
//	** FLAGS include:
//	**
//	**    1          Strict canonical JSON text
//	**    2          JSON text perhaps with JSON-5 extensions
//	**    4          Superficially appears to be JSONB
//	**    5          Canonical JSON text or superficial JSONB
//	**    6          JSON-5 text or superficial JSONB
//	**    8          Strict JSONB
//	**    9          Canonical JSON text or strict JSONB
//	**    10         JSON-5 text or strict JSONB
//	**
//	** Other flag combinations are redundant.  For example, every canonical
//	** JSON text is also well-formed JSON-5 text, so FLAG values 2 and 3
//	** are the same.  Similarly, any input that passes a strict JSONB validation
//	** will also pass the superficial validation so 12 through 15 are the same
//	** as 8 through 11 respectively.
//	**
//	** This routine runs in linear time to validate text and when doing strict
//	** JSONB validation.  Superficial JSONB validation is constant time,
//	** assuming the BLOB is already in memory.  The performance advantage
//	** of superficial JSONB validation is why that option is provided.
//	** Application developers can choose to do fast superficial validation or
//	** slower strict validation, according to their specific needs.
//	**
//	** Only the lower four bits of the FLAGS argument are currently used.
//	** Higher bits are reserved for future expansion.   To facilitate
//	** compatibility, the current implementation raises an error if any bit
//	** in FLAGS is set other than the lower four bits.
//	**
//	** The original circa 2015 implementation of the JSON routines in
//	** SQLite only supported canonical RFC-8259 JSON text and the json_valid()
//	** function only accepted one argument.  That is why the default value
//	** for the FLAGS argument is 1, since FLAGS=1 causes this routine to only
//	** recognize canonical RFC-8259 JSON text as valid.  The extra FLAGS
//	** argument was added when the JSON routines were extended to support
//	** JSON5-like extensions and binary JSONB stored in BLOBs.
//	**
//	** Return Values:
//	**
//	**   *   Raise an error if FLAGS is outside the range of 1 to 15.
//	**   *   Return NULL if the input is NULL
//	**   *   Return 1 if the input is well-formed.
//	**   *   Return 0 if the input is not well-formed.

**
** OVERVIEW
**
**  The RBU extension requires that the RBU update be packaged as an
**  SQLite database. The tables it expects to find are described in
**  sqlite3rbu.h.  Essentially, for each table xyz in the target database
**  that the user wishes to write to, a corresponding data_xyz table is
**  created in the RBU database and populated with one row for each row to
**  update, insert or delete from the target table.
**
**  The update proceeds in three stages:
**
**  1) The database is updated. The modified database pages are written
**     to a *-oal file. A *-oal file is just like a *-wal file, except
**     that it is named "<database>-oal" instead of "<database>-wal".
**     Because regular SQLite clients do not look for file named
**     "<database>-oal", they go on using the original database in
**     rollback mode while the *-oal file is being generated.
**
**     During this stage RBU does not update the database by writing
**     directly to the target tables. Instead it creates "imposter"
**     tables using the SQLITE_TESTCTRL_IMPOSTER interface that it uses
**     to update each b-tree individually. All updates required by each
**     b-tree are completed before moving on to the next, and all
**     updates are done in sorted key order.
**
**  2) The "<database>-oal" file is moved to the equivalent "<database>-wal"
**     location using a call to rename(2). Before doing this the RBU
**     module takes an EXCLUSIVE lock on the database file, ensuring
**     that there are no other active readers.
**
**     Once the EXCLUSIVE lock is released, any other database readers
**     detect the new *-wal file and read the database in wal mode. At
**     this point they see the new version of the database - including
**     the updates made as part of the RBU update.
**
**  3) The new *-wal file is checkpointed. This proceeds in the same way
**     as a regular database checkpoint, except that a single frame is
**     checkpointed each time sqlite3rbu_step() is called. If the RBU
**     handle is closed before the entire *-wal file is checkpointed,
**     the checkpoint progress is saved in the RBU database and the
**     checkpoint can be resumed by another RBU client at some point in
**     the future.
**
** POTENTIAL PROBLEMS
**
**  The rename() call might not be portable. And RBU is not currently
**  syncing the directory after renaming the file.
**
**  When state is saved, any commit to the *-oal file and the commit to
**  the RBU update database are not atomic. So if the power fails at the
**  wrong moment they might get out of sync. As the main database will be
**  committed before the RBU update database this will likely either just
**  pass unnoticed, or result in SQLITE_CONSTRAINT errors (due to UNIQUE
**  constraint violations).
**
**  If some client does modify the target database mid RBU update, or some
**  other error occurs, the RBU extension will keep throwing errors. It's
**  not really clear how to get out of this state. The system could just
**  by delete the RBU update database and *-oal file and have the device
**  download the update again and start over.
**
**  At present, for an UPDATE, both the new.* and old.* records are
**  collected in the rbu_xyz table. And for both UPDATEs and DELETEs all
**  fields are collected.  This means we're probably writing a lot more
**  data to disk when saving the state of an ongoing update to the RBU
**  update database than is strictly necessary.

/*
** SUMMARY
**
** Writing a transaction containing a large number of operations on
** b-tree indexes that are collectively larger than the available cache
** memory can be very inefficient.
**
** The problem is that in order to update a b-tree, the leaf page (at least)
** containing the entry being inserted or deleted must be modified. If the
** working set of leaves is larger than the available cache memory, then a
** single leaf that is modified more than once as part of the transaction
** may be loaded from or written to the persistent media multiple times.
** Additionally, because the index updates are likely to be applied in
** random order, access to pages within the database is also likely to be in
** random order, which is itself quite inefficient.
**
** One way to improve the situation is to sort the operations on each index
** by index key before applying them to the b-tree. This leads to an IO
** pattern that resembles a single linear scan through the index b-tree,
** and all but guarantees each modified leaf page is loaded and stored
** exactly once. SQLite uses this trick to improve the performance of
** CREATE INDEX commands. This extension allows it to be used to improve
** the performance of large transactions on existing databases.
**
** Additionally, this extension allows the work involved in writing the
** large transaction to be broken down into sub-transactions performed
** sequentially by separate processes. This is useful if the system cannot
** guarantee that a single update process will run for long enough to apply
** the entire update, for example because the update is being applied on a
** mobile device that is frequently rebooted. Even after the writer process
** has committed one or more sub-transactions, other database clients continue
** to read from the original database snapshot. In other words, partially
** applied transactions are not visible to other clients.
**
** "RBU" stands for "Resumable Bulk Update". As in a large database update
** transmitted via a wireless network to a mobile device. A transaction
** applied using this extension is hence refered to as an "RBU update".
**
**
** LIMITATIONS
**
** An "RBU update" transaction is subject to the following limitations:
**
**   * The transaction must consist of INSERT, UPDATE and DELETE operations
**     only.
**
**   * INSERT statements may not use any default values.
**
**   * UPDATE and DELETE statements must identify their target rows by
**     non-NULL PRIMARY KEY values. Rows with NULL values stored in PRIMARY
**     KEY fields may not be updated or deleted. If the table being written
**     has no PRIMARY KEY, affected rows must be identified by rowid.
**
**   * UPDATE statements may not modify PRIMARY KEY columns.
**
**   * No triggers will be fired.
**
**   * No foreign key violations are detected or reported.
**
**   * CHECK constraints are not enforced.
**
**   * No constraint handling mode except for "OR ROLLBACK" is supported.
**
**
** PREPARATION
**
** An "RBU update" is stored as a separate SQLite database. A database
** containing an RBU update is an "RBU database". For each table in the
** target database to be updated, the RBU database should contain a table
** named "data_<target name>" containing the same set of columns as the
** target table, and one more - "rbu_control". The data_% table should
** have no PRIMARY KEY or UNIQUE constraints, but each column should have
** the same type as the corresponding column in the target database.
** The "rbu_control" column should have no type at all. For example, if
** the target database contains:
**
**   CREATE TABLE t1(a INTEGER PRIMARY KEY, b TEXT, c UNIQUE);
**
** Then the RBU database should contain:
**
**   CREATE TABLE data_t1(a INTEGER, b TEXT, c, rbu_control);
**
** The order of the columns in the data_% table does not matter.
**
** Instead of a regular table, the RBU database may also contain virtual
** tables or views named using the data_<target> naming scheme.
**
** Instead of the plain data_<target> naming scheme, RBU database tables
** may also be named data<integer>_<target>, where <integer> is any sequence
** of zero or more numeric characters (0-9). This can be significant because
** tables within the RBU database are always processed in order sorted by
** name. By judicious selection of the <integer> portion of the names
** of the RBU tables the user can therefore control the order in which they
** are processed. This can be useful, for example, to ensure that "external
** content" FTS4 tables are updated before their underlying content tables.
**
** If the target database table is a virtual table or a table that has no
** PRIMARY KEY declaration, the data_% table must also contain a column
** named "rbu_rowid". This column is mapped to the table's implicit primary
** key column - "rowid". Virtual tables for which the "rowid" column does
** not function like a primary key value cannot be updated using RBU. For
** example, if the target db contains either of the following:
**
**   CREATE VIRTUAL TABLE x1 USING fts3(a, b);
**   CREATE TABLE x1(a, b)
**
** then the RBU database should contain:
**
**   CREATE TABLE data_x1(a, b, rbu_rowid, rbu_control);
**
** All non-hidden columns (i.e. all columns matched by "SELECT *") of the
** target table must be present in the input table. For virtual tables,
** hidden columns are optional - they are updated by RBU if present in
** the input table, or not otherwise. For example, to write to an fts4
** table with a hidden languageid column such as:
**
**   CREATE VIRTUAL TABLE ft1 USING fts4(a, b, languageid='langid');
**
** Either of the following input table schemas may be used:
**
**   CREATE TABLE data_ft1(a, b, langid, rbu_rowid, rbu_control);
**   CREATE TABLE data_ft1(a, b, rbu_rowid, rbu_control);
**
** For each row to INSERT into the target database as part of the RBU
** update, the corresponding data_% table should contain a single record
** with the "rbu_control" column set to contain integer value 0. The
** other columns should be set to the values that make up the new record
** to insert.
**
** If the target database table has an INTEGER PRIMARY KEY, it is not
** possible to insert a NULL value into the IPK column. Attempting to
** do so results in an SQLITE_MISMATCH error.
**
** For each row to DELETE from the target database as part of the RBU
** update, the corresponding data_% table should contain a single record
** with the "rbu_control" column set to contain integer value 1. The
** real primary key values of the row to delete should be stored in the
** corresponding columns of the data_% table. The values stored in the
** other columns are not used.
**
** For each row to UPDATE from the target database as part of the RBU
** update, the corresponding data_% table should contain a single record
** with the "rbu_control" column set to contain a value of type text.
** The real primary key values identifying the row to update should be
** stored in the corresponding columns of the data_% table row, as should
** the new values of all columns being update. The text value in the
** "rbu_control" column must contain the same number of characters as
** there are columns in the target database table, and must consist entirely
** of 'x' and '.' characters (or in some special cases 'd' - see below). For
** each column that is being updated, the corresponding character is set to
** 'x'. For those that remain as they are, the corresponding character of the
** rbu_control value should be set to '.'. For example, given the tables
** above, the update statement:
**
**   UPDATE t1 SET c = 'usa' WHERE a = 4;
**
** is represented by the data_t1 row created by:
**
**   INSERT INTO data_t1(a, b, c, rbu_control) VALUES(4, NULL, 'usa', '..x');
**
** Instead of an 'x' character, characters of the rbu_control value specified
** for UPDATEs may also be set to 'd'. In this case, instead of updating the
** target table with the value stored in the corresponding data_% column, the
** user-defined SQL function "rbu_delta()" is invoked and the result stored in
** the target table column. rbu_delta() is invoked with two arguments - the
** original value currently stored in the target table column and the
** value specified in the data_xxx table.
**
** For example, this row:
**
**   INSERT INTO data_t1(a, b, c, rbu_control) VALUES(4, NULL, 'usa', '..d');
**
** is similar to an UPDATE statement such as:
**
**   UPDATE t1 SET c = rbu_delta(c, 'usa') WHERE a = 4;
**
** Finally, if an 'f' character appears in place of a 'd' or 's' in an
** ota_control string, the contents of the data_xxx table column is assumed
** to be a "fossil delta" - a patch to be applied to a blob value in the
** format used by the fossil source-code management system. In this case
** the existing value within the target database table must be of type BLOB.
** It is replaced by the result of applying the specified fossil delta to
** itself.
**
** If the target database table is a virtual table or a table with no PRIMARY
** KEY, the rbu_control value should not include a character corresponding
** to the rbu_rowid value. For example, this:
**
**   INSERT INTO data_ft1(a, b, rbu_rowid, rbu_control)
**       VALUES(NULL, 'usa', 12, '.x');
**
** causes a result similar to:
**
**   UPDATE ft1 SET b = 'usa' WHERE rowid = 12;
**
** The data_xxx tables themselves should have no PRIMARY KEY declarations.
** However, RBU is more efficient if reading the rows in from each data_xxx
** table in "rowid" order is roughly the same as reading them sorted by
** the PRIMARY KEY of the corresponding target database table. In other
** words, rows should be sorted using the destination table PRIMARY KEY
** fields before they are inserted into the data_xxx tables.
**
** USAGE
**
** The API declared below allows an application to apply an RBU update
** stored on disk to an existing target database. Essentially, the
** application:
**
**     1) Opens an RBU handle using the sqlite3rbu_open() function.
**
**     2) Registers any required virtual table modules with the database
**        handle returned by sqlite3rbu_db(). Also, if required, register
**        the rbu_delta() implementation.
**
**     3) Calls the sqlite3rbu_step() function one or more times on
**        the new handle. Each call to sqlite3rbu_step() performs a single
**        b-tree operation, so thousands of calls may be required to apply
**        a complete update.
**
**     4) Calls sqlite3rbu_close() to close the RBU update handle. If
**        sqlite3rbu_step() has been called enough times to completely
**        apply the update to the target database, then the RBU database
**        is marked as fully applied. Otherwise, the state of the RBU
**        update application is saved in the RBU database for later
**        resumption.
**
** See comments below for more detail on APIs.
**
** If an update is only partially applied to the target database by the
** time sqlite3rbu_close() is called, various state information is saved
** within the RBU database. This allows subsequent processes to automatically
** resume the RBU update from where it left off.
**
** To remove all RBU extension state information, returning an RBU database
** to its original contents, it is sufficient to drop all tables that begin
** with the prefix "rbu_"
**
** DATABASE LOCKING
**
** An RBU update may not be applied to a database in WAL mode. Attempting
** to do so is an error (SQLITE_ERROR).
**
** While an RBU handle is open, a SHARED lock may be held on the target
** database file. This means it is possible for other clients to read the
** database, but not to write it.
**
** If an RBU update is started and then suspended before it is completed,
** then an external client writes to the database, then attempting to resume
** the suspended RBU update is also an error (SQLITE_BUSY).

/**************************************************************************
** Beginning of RBU VFS shim methods. The VFS shim modifies the behaviour
** of a standard VFS in the following ways:
**
** 1. Whenever the first page of a main database file is read or
**    written, the value of the change-counter cookie is stored in
**    rbu_file.iCookie. Similarly, the value of the "write-version"
**    database header field is stored in rbu_file.iWriteVer. This ensures
**    that the values are always trustworthy within an open transaction.
**
** 2. Whenever an SQLITE_OPEN_WAL file is opened, the (rbu_file.pWalFd)
**    member variable of the associated database file descriptor is set
**    to point to the new file. A mutex protected linked list of all main
**    db fds opened using a particular RBU VFS is maintained at
**    rbu_vfs.pMain to facilitate this.
**
** 3. Using a new file-control "SQLITE_FCNTL_RBU", a main db rbu_file
**    object can be marked as the target database of an RBU update. This
**    turns on the following extra special behaviour:
**
** 3a. If xAccess() is called to check if there exists a *-wal file
**     associated with an RBU target database currently in RBU_STAGE_OAL
**     stage (preparing the *-oal file), the following special handling
**     applies:
**
**      * if the *-wal file does exist, return SQLITE_CANTOPEN. An RBU
**        target database may not be in wal mode already.
**
**      * if the *-wal file does not exist, set the output parameter to
**        non-zero (to tell SQLite that it does exist) anyway.
**
**     Then, when xOpen() is called to open the *-wal file associated with
**     the RBU target in RBU_STAGE_OAL stage, instead of opening the *-wal
**     file, the rbu vfs opens the corresponding *-oal file instead.
**
** 3b. The *-shm pages returned by xShmMap() for a target db file in
**     RBU_STAGE_OAL mode are actually stored in heap memory. This is to
**     avoid creating a *-shm file on disk. Additionally, xShmLock() calls
**     are no-ops on target database files in RBU_STAGE_OAL mode. This is
**     because assert() statements in some VFS implementations fail if
**     xShmLock() is called before xShmMap().
**
** 3c. If an EXCLUSIVE lock is attempted on a target database file in any
**     mode except RBU_STAGE_DONE (all work completed and checkpointed), it
**     fails with an SQLITE_BUSY error. This is to stop RBU connections
**     from automatically checkpointing a *-wal (or *-oal) file from within
**     sqlite3_close().
**
** 3d. In RBU_STAGE_CAPTURE mode, all xRead() calls on the wal file, and
**     all xWrite() calls on the target database file perform no IO.
**     Instead the frame and page numbers that would be read and written
**     are recorded. Additionally, successful attempts to obtain exclusive
**     xShmLock() WRITER, CHECKPOINTER and READ0 locks on the target
**     database file are recorded. xShmLock() calls to unlock the same
**     locks are no-ops (so that once obtained, these locks are never
**     relinquished). Finally, calls to xSync() on the target database
**     file fail with SQLITE_NOTICE errors.

** by the following number of bytes for the same purpose.
 */

// C documentation
//
//	/*
//	** Page paths:
//	**
//	**   The value of the 'path' column describes the path taken from the
//	**   root-node of the b-tree structure to each page. The value of the
//	**   root-node path is '/'.
//	**
//	**   The value of the path for the left-most child page of the root of
//	**   a b-tree is '/000/'. (Btrees store content ordered from left to right
//	**   so the pages to the left have smaller keys than the pages to the right.)
//	**   The next to left-most child of the root page is
//	**   '/001', and so on, each sibling page identified by a 3-digit hex
//	**   value. The children of the 451st left-most sibling have paths such
//	**   as '/1c2/000/, '/1c2/001/' etc.
//	**
//	**   Overflow pages are specified by appending a '+' character and a
//	**   six-digit hexadecimal value to the path to the cell they are linked
//	**   from. For example, the three overflow pages in a chain linked from
//	**   the left-most cell of the 450th child of the root page are identified
//	**   by the paths:
//	**
//	**      '/1c2/000+000000'         // First page in overflow chain
//	**      '/1c2/000+000001'         // Second page in overflow chain
//	**      '/1c2/000+000002'         // Third page in overflow chain
//	**
//	**   If the paths are sorted using the BINARY collation sequence, then
//	**   the overflow pages associated with a cell will appear earlier in the
//	**   sort-order than its child page:
//	**
//	**      '/1c2/000/'               // Left-most child of 451st child of root

** This file contains an implementation of the "sqlite_dbpage" virtual table.
**
** The sqlite_dbpage virtual table is used to read or write whole raw

** retrieved.
**
** Usage example:
**
**    SELECT data FROM sqlite_dbpage('aux1') WHERE pgno=123;
**
** This is an eponymous virtual table so it does not need to be created before
** use.  The optional argument to the sqlite_dbpage() table name is the
** schema for the database file that is to be read.  The default schema is
** "main".
**
** The data field of sqlite_dbpage table can be updated.  The new
** value must be a BLOB which is the correct page size, otherwise the
** update fails.  Rows may not be deleted or inserted.

/*
** RECORD FORMAT:
**
** The following record format is similar to (but not compatible with) that
** used in SQLite database files. This format is used as part of the
** change-set binary format, and so must be architecture independent.
**
** Unlike the SQLite database record format, each field is self-contained -
** there is no separation of header and data. Each field begins with a
** single byte describing its type, as follows:
**
**       0x00: Undefined value.
**       0x01: Integer value.
**       0x02: Real value.
**       0x03: Text value.
**       0x04: Blob value.
**       0x05: SQL NULL value.
**
** Note that the above match the definitions of SQLITE_INTEGER, SQLITE_TEXT
** and so on in sqlite3.h. For undefined and NULL values, the field consists
** only of the single type byte. For other types of values, the type byte
** is followed by:
**
**   Text values:
**     A varint containing the number of bytes in the value (encoded using
**     UTF-8). Followed by a buffer containing the UTF-8 representation
**     of the text value. There is no nul terminator.
**
**   Blob values:
**     A varint containing the number of bytes in the value, followed by
**     a buffer containing the value itself.
**
**   Integer values:
**     An 8-byte big-endian integer value.
**
**   Real values:
**     An 8-byte big-endian IEEE 754-2008 real value.
**
** Varint values are encoded in the same way as varints in the SQLite
** record format.
**
** CHANGESET FORMAT:
**
** A changeset is a collection of DELETE, UPDATE and INSERT operations on
** one or more tables. Operations on a single table are grouped together,
** but may occur in any order (i.e. deletes, updates and inserts are all
** mixed together).
**
** Each group of changes begins with a table header:
**
**   1 byte: Constant 0x54 (capital 'T')
**   Varint: Number of columns in the table.
**   nCol bytes: 0x01 for PK columns, 0x00 otherwise.
**   N bytes: Unqualified table name (encoded using UTF-8). Nul-terminated.
**
** Followed by one or more changes to the table.
**
**   1 byte: Either SQLITE_INSERT (0x12), UPDATE (0x17) or DELETE (0x09).
**   1 byte: The "indirect-change" flag.
**   old.* record: (delete and update only)
**   new.* record: (insert and update only)
**
** The "old.*" and "new.*" records, if present, are N field records in the
** format described above under "RECORD FORMAT", where N is the number of
** columns in the table. The i'th field of each record is associated with
** the i'th column of the table, counting from left to right in the order
** in which columns were declared in the CREATE TABLE statement.
**
** The new.* record that is part of each INSERT change contains the values
** that make up the new row. Similarly, the old.* record that is part of each
** DELETE change contains the values that made up the row that was deleted
** from the database. In the changeset format, the records that are part
** of INSERT or DELETE changes never contain any undefined (type byte 0x00)
** fields.
**
** Within the old.* record associated with an UPDATE change, all fields
** associated with table columns that are not PRIMARY KEY columns and are
** not modified by the UPDATE change are set to "undefined". Other fields
** are set to the values that made up the row before the UPDATE that the
** change records took place. Within the new.* record, fields associated
** with table columns modified by the UPDATE change contain the new
** values. Fields associated with table columns that are not modified
** are set to "undefined".
**
** PATCHSET FORMAT:
**
** A patchset is also a collection of changes. It is similar to a changeset,
** but leaves undefined those fields that are not useful if no conflict
** resolution is required when applying the changeset.
**
** Each group of changes begins with a table header:
**
**   1 byte: Constant 0x50 (capital 'P')
**   Varint: Number of columns in the table.
**   nCol bytes: 0x01 for PK columns, 0x00 otherwise.
**   N bytes: Unqualified table name (encoded using UTF-8). Nul-terminated.
**
** Followed by one or more changes to the table.
**
**   1 byte: Either SQLITE_INSERT (0x12), UPDATE (0x17) or DELETE (0x09).
**   1 byte: The "indirect-change" flag.
**   single record: (PK fields for DELETE, PK and modified fields for UPDATE,
**                   full record for INSERT).
**
** As in the changeset format, each field of the single record that is part
** of a patchset change is associated with the correspondingly positioned
** table column, counting from left to right within the CREATE TABLE
** statement.
**
** For a DELETE change, all fields within the record except those associated
** with PRIMARY KEY columns are omitted. The PRIMARY KEY fields contain the
** values identifying the row to delete.
**
** For an UPDATE change, all fields except those associated with PRIMARY KEY
** columns and columns that are modified by the UPDATE are set to "undefined".
** PRIMARY KEY fields contain the values identifying the table row to update,
** and fields associated with modified columns contain the new column values.
**
** The records associated with INSERT changes are in the same format as for
** changesets. It is not possible for a record associated with an INSERT
** change to contain a field set to "undefined".
**
** REBASE BLOB FORMAT:
**
** A rebase blob may be output by sqlite3changeset_apply_v2() and its
** streaming equivalent for use with the sqlite3_rebaser APIs to rebase
** existing changesets. A rebase blob contains one entry for each conflict
** resolved using either the OMIT or REPLACE strategies within the apply_v2()
** call.
**
** The format used for a rebase blob is very similar to that used for
** changesets. All entries related to a single table are grouped together.
**
** Each group of entries begins with a table header in changeset format:
**
**   1 byte: Constant 0x54 (capital 'T')
**   Varint: Number of columns in the table.
**   nCol bytes: 0x01 for PK columns, 0x00 otherwise.
**   N bytes: Unqualified table name (encoded using UTF-8). Nul-terminated.
**
** Followed by one or more entries associated with the table.
**
**   1 byte: Either SQLITE_INSERT (0x12), DELETE (0x09).
**   1 byte: Flag. 0x01 for REPLACE, 0x00 for OMIT.
**   record: (in the record format defined above).
**
** In a rebase blob, the first field is set to SQLITE_INSERT if the change
** that caused the conflict was an INSERT or UPDATE, or to SQLITE_DELETE if
** it was a DELETE. The second field is set to 0x01 if the conflict
** resolution strategy was REPLACE, or 0x00 if it was OMIT.
**
** If the change that caused the conflict was a DELETE, then the single
** record is a copy of the old.* record from the original changeset. If it
** was an INSERT, then the single record is a copy of the new.* record. If
** the conflicting change was an UPDATE, then the single record is a copy
** of the new.* record with the PK fields filled in based on the original
** old.* record.

//	**    fts5YYCODETYPE         is the data type used to store the integer codes
//	**                       that represent terminal and non-terminal symbols.
//	**                       "unsigned char" is used if there are fewer than
//	**                       256 symbols.  Larger types otherwise.
//	**    fts5YYNOCODE           is a number of type fts5YYCODETYPE that is not used for
//	**                       any terminal or nonterminal symbol.
//	**    fts5YYFALLBACK         If defined, this indicates that one or more tokens
//	**                       (also known as: "terminal symbols") have fall-back
//	**                       values which should be used if the original symbol
//	**                       would not parse.  This permits keywords to sometimes
//	**                       be used as identifiers, for example.
//	**    fts5YYACTIONTYPE       is the data type used for "action codes" - numbers
//	**                       that indicate what to do in response to the next
//	**                       token.
//	**    sqlite3Fts5ParserFTS5TOKENTYPE     is the data type used for minor type for terminal
//	**                       symbols.  Background: A "minor type" is a semantic
//	**                       value associated with a terminal or non-terminal
//	**                       symbols.  For example, for an "ID" terminal symbol,
//	**                       the minor type might be the name of the identifier.
//	**                       Each non-terminal can have a different minor type.
//	**                       Terminal symbols all have the same minor type, though.
//	**                       This macros defines the minor type for terminal
//	**                       symbols.
//	**    fts5YYMINORTYPE        is the data type used for all minor types.
//	**                       This is typically a union of many types, one of
//	**                       which is sqlite3Fts5ParserFTS5TOKENTYPE.  The entry in the union
//	**                       for terminal symbols is called "fts5yy0".
//	**    fts5YYSTACKDEPTH       is the maximum depth of the parser's stack.  If
//	**                       zero the stack is dynamically sized using realloc()

//	**                       defined, then do no error processing.
//	**    fts5YYNSTATE           the combined number of states.

//	** Suppose the action integer is N.  Then the action is determined as

//	**     and fts5YY_MAX_REDUCE
//	**
//	** The action table is constructed as a single large table named fts5yy_action[].
//	** Given state S and lookahead X, the action is computed as either:
//	**
//	**    (A)   N = fts5yy_action[ fts5yy_shift_ofst[S] + X ]
//	**    (B)   N = fts5yy_default[S]
//	**
//	** The (A) formula is preferred.  The B formula is used instead if
//	** fts5yy_lookahead[fts5yy_shift_ofst[S]+X] is not equal to X.
//	**
//	** The formulas above are for computing the action when the lookahead is
//	** a terminal symbol.  If the lookahead is a non-terminal (as occurs after
//	** a reduce action) then the fts5yy_reduce_ofst[] array is used in place of
//	** the fts5yy_shift_ofst[] array.
//	**
//	** The following are the tables generated in this section:
//	**
//	**  fts5yy_action[]        A single table containing all actions.
//	**  fts5yy_lookahead[]     A table containing the lookahead for each entry in
//	**                     fts5yy_action.  Used to detect hash collisions.

//	**                     shifting terminals.
//	**  fts5yy_reduce_ofst[]   For each state, the offset into fts5yy_action for
//	**                     shifting non-terminals after a reduce.

 */

/* #include "fts5Int.h" */

/*
** Overview:
**
** The %_data table contains all the FTS indexes for an FTS5 virtual table.
** As well as the main term index, there may be up to 31 prefix indexes.
** The format is similar to FTS3/4, except that:
**
**   * all segment b-tree leaf data is stored in fixed size page records
**     (e.g. 1000 bytes). A single doclist may span multiple pages. Care is
**     taken to ensure it is possible to iterate in either direction through
**     the entries in a doclist, or to seek to a specific entry within a
**     doclist, without loading it into memory.
**
**   * large doclists that span many pages have associated "doclist index"
**     records that contain a copy of the first rowid on each page spanned by
**     the doclist. This is used to speed up seek operations, and merges of
**     large doclists with very small doclists.
**
**   * extra fields in the "structure record" record the state of ongoing
**     incremental merge operations.
**
 */

/*
** There are two versions of the format used for the structure record:
**
**   1. the legacy format, that may be read by all fts5 versions, and
**
**   2. the V2 format, which is used by contentless_delete=1 databases.
**
** Both begin with a 4-byte "configuration cookie" value. Then, a legacy
** format structure record contains a varint - the number of levels in
** the structure. Whereas a V2 structure record contains the constant
** 4 bytes [0xff 0x00 0x00 0x01]. This is unambiguous as the value of a
** varint has to be at least 16256 to begin with "0xFF". And the default
** maximum number of levels is 64.
**
** See below for more on structure record formats.
 */

/*
** Details:
**
** The %_data table managed by this module,
**
**     CREATE TABLE %_data(id INTEGER PRIMARY KEY, block BLOB);
**
** , contains the following 6 types of records. See the comments surrounding
** the FTS5_*_ROWID macros below for a description of how %_data rowids are
** assigned to each fo them.
**
** 1. Structure Records:
**
**   The set of segments that make up an index - the index structure - are
**   recorded in a single record within the %_data table. The record consists
**   of a single 32-bit configuration cookie value followed by a list of
**   SQLite varints.
**
**   If the structure record is a V2 record, the configuration cookie is
**   followed by the following 4 bytes: [0xFF 0x00 0x00 0x01].
**
**   Next, the record continues with three varints:
**
**     + number of levels,
**     + total number of segments on all levels,
**     + value of write counter.
**
**   Then, for each level from 0 to nMax:
**
**     + number of input segments in ongoing merge.
**     + total number of segments in level.
**     + for each segment from oldest to newest:
**         + segment id (always > 0)
**         + first leaf page number (often 1, always greater than 0)
**         + final leaf page number
**
**      Then, for V2 structures only:
**
**         + lower origin counter value,
**         + upper origin counter value,
**         + the number of tombstone hash pages.
**
** 2. The Averages Record:
**
**   A single record within the %_data table. The data is a list of varints.
**   The first value is the number of rows in the index. Then, for each column
**   from left to right, the total number of tokens in the column for all
**   rows of the table.
**
** 3. Segment leaves:
**
**   TERM/DOCLIST FORMAT:
**
**     Most of each segment leaf is taken up by term/doclist data. The
**     general format of term/doclist, starting with the first term
**     on the leaf page, is:
**
**         varint : size of first term
**         blob:    first term data
**         doclist: first doclist
**         zero-or-more {
**           varint:  number of bytes in common with previous term
**           varint:  number of bytes of new term data (nNew)
**           blob:    nNew bytes of new term data
**           doclist: next doclist
**         }
**
**     doclist format:
**
**         varint:  first rowid
**         poslist: first poslist
**         zero-or-more {
**           varint:  rowid delta (always > 0)
**           poslist: next poslist
**         }
**
**     poslist format:
**
**         varint: size of poslist in bytes multiplied by 2, not including
**                 this field. Plus 1 if this entry carries the "delete" flag.
**         collist: collist for column 0
**         zero-or-more {
**           0x01 byte
**           varint: column number (I)
**           collist: collist for column I
**         }
**
**     collist format:
**
**         varint: first offset + 2
**         zero-or-more {
**           varint: offset delta + 2
**         }
**
**   PAGE FORMAT
**
**     Each leaf page begins with a 4-byte header containing 2 16-bit
**     unsigned integer fields in big-endian format. They are:
**
**       * The byte offset of the first rowid on the page, if it exists
**         and occurs before the first term (otherwise 0).
**
**       * The byte offset of the start of the page footer. If the page
**         footer is 0 bytes in size, then this field is the same as the
**         size of the leaf page in bytes.
**
**     The page footer consists of a single varint for each term located
**     on the page. Each varint is the byte offset of the current term
**     within the page, delta-compressed against the previous value. In
**     other words, the first varint in the footer is the byte offset of
**     the first term, the second is the byte offset of the second less that
**     of the first, and so on.
**
**     The term/doclist format described above is accurate if the entire
**     term/doclist data fits on a single leaf page. If this is not the case,
**     the format is changed in two ways:
**
**       + if the first rowid on a page occurs before the first term, it
**         is stored as a literal value:
**
**             varint:  first rowid
**
**       + the first term on each page is stored in the same way as the
**         very first term of the segment:
**
**             varint : size of first term
**             blob:    first term data
**
** 5. Segment doclist indexes:
**
**   Doclist indexes are themselves b-trees, however they usually consist of
**   a single leaf record only. The format of each doclist index leaf page
**   is:
**
**     * Flags byte. Bits are:
**         0x01: Clear if leaf is also the root page, otherwise set.
**
**     * Page number of fts index leaf page. As a varint.
**
**     * First rowid on page indicated by previous field. As a varint.
**
**     * A list of varints, one for each subsequent termless page. A
**       positive delta if the termless page contains at least one rowid,
**       or an 0x00 byte otherwise.
**
**   Internal doclist index nodes are:
**
**     * Flags byte. Bits are:
**         0x01: Clear for root page, otherwise set.
**
**     * Page number of first child page. As a varint.
**
**     * Copy of first rowid on page indicated by previous field. As a varint.
**
**     * A list of delta-encoded varints - the first rowid on each subsequent
**       child page.
**
** 6. Tombstone Hash Page
**
**   These records are only ever present in contentless_delete=1 tables.
**   There are zero or more of these associated with each segment. They
**   are used to store the tombstone rowids for rows contained in the
**   associated segments.
**
**   The set of nHashPg tombstone hash pages associated with a single
**   segment together form a single hash table containing tombstone rowids.
**   To find the page of the hash on which a key might be stored:
**
**       iPg = (rowid % nHashPg)
**
**   Then, within page iPg, which has nSlot slots:
**
**       iSlot = (rowid / nHashPg) % nSlot
**
**   Each tombstone hash page begins with an 8 byte header:
**
**     1-byte:  Key-size (the size in bytes of each slot). Either 4 or 8.
**     1-byte:  rowid-0-tombstone flag. This flag is only valid on the
**              first tombstone hash page for each segment (iPg=0). If set,
**              the hash table contains rowid 0. If clear, it does not.
**              Rowid 0 is handled specially.
**     2-bytes: unused.
**     4-bytes: Big-endian integer containing number of entries on page.
**
**   Following this are nSlot 4 or 8 byte slots (depending on the key-size
**   in the first byte of the page header). The number of slots may be
**   determined based on the size of the page record and the key-size:
**
**     nSlot = (nByte - 8) / key-size
 */

/*
** Rowids for the averages and structure records in the %_data table.
 */

/*
** Macros determining the rowids used by segment leaves and dlidx leaves
** and nodes. All nodes and leaves are stored in the %_data table with large

**
** Each segment has a unique non-zero 16-bit id.
**
** The rowid for each segment leaf is found by passing the segment id and
** the leaf page number to the FTS5_SEGMENT_ROWID macro. Leaves are numbered
** sequentially starting from 1.

** Each time a blob is read from the %_data table, it is padded with this
** many zero bytes. This makes it easier to decode the various record formats
** without overreading if the records are corrupt.

** NOTES ON TRANSACTIONS:
**
** SQLite invokes the following virtual table methods as transactions are
** opened and closed by the user:
**
**     xBegin():    Start of a new transaction.
**     xSync():     Initial part of two-phase commit.
**     xCommit():   Final part of two-phase commit.
**     xRollback(): Rollback the transaction.
**
** Anything that is required as part of a commit that may fail is performed
** in the xSync() callback. Current versions of SQLite ignore any errors
** returned by xCommit().
**
** And as sub-transactions are opened/closed:
**
**     xSavepoint(int S):  Open savepoint S.
**     xRelease(int S):    Commit and close savepoint S.
**     xRollbackTo(int S): Rollback to start of savepoint S.
**
** During a write-transaction the fts5_index.c module may cache some data
** in-memory. It is flushed to disk whenever xSync(), xRelease() or
** xSavepoint() is called. And discarded whenever xRollback() or xRollbackTo()
** is called.
**
** Additionally, if SQLITE_DEBUG is defined, an instance of the following
** structure is used to record the current transaction state. This information
** is not required, but it is used in the assert() statements executed by
** function fts5CheckTransactionState() (see below).

//	**   5. A < or <= constraint against the rowid column.
//	**   6. A > or >= constraint against the rowid column.

//	** Within the ORDER BY, the following are supported:
//	**
//	**   5. ORDER BY rank [ASC|DESC]
//	**   6. ORDER BY rowid [ASC|DESC]
//	**
//	** Information for the xFilter call is passed via both the idxNum and
//	** idxStr variables. Specifically, idxNum is a bitmask of the following
//	** flags used to encode the ORDER BY clause:
//	**
//	**     FTS5_BI_ORDER_RANK
//	**     FTS5_BI_ORDER_ROWID
//	**     FTS5_BI_ORDER_DESC
//	**
//	** idxStr is used to encode data from the WHERE clause. For each argument
//	** passed to the xFilter method, the following is appended to idxStr:
//	**
//	**   Match against table column:            "m"
//	**   Match against rank column:             "r"
//	**   Match against other column:            "M<column-number>"
//	**   LIKE  against other column:            "L<column-number>"
//	**   GLOB  against other column:            "G<column-number>"
//	**   Equality constraint against the rowid: "="
//	**   A < or <= against the rowid:           "<"
//	**   A > or >= against the rowid:           ">"
//	**
//	** This function ensures that there is at most one "r" or "=". And that if
//	** there exists an "=" then there is no "<" or ">".
//	**
//	** Costs are assigned as follows:
//	**
//	**  a) If an unusable MATCH operator is present in the WHERE clause, the
//	**     cost is unconditionally set to 1e50 (a really big number).
//	**
//	**  a) If a MATCH operator is present, the cost depends on the other
//	**     constraints also present. As follows:
//	**
//	**       * No other constraints:         cost=1000.0
//	**       * One rowid range constraint:   cost=750.0
//	**       * Both rowid range constraints: cost=500.0
//	**       * An == rowid constraint:       cost=100.0
//	**
//	**  b) Otherwise, if there is no MATCH:
//	**
//	**       * No other constraints:         cost=1000000.0
//	**       * One rowid range constraint:   cost=750000.0
//	**       * Both rowid range constraints: cost=250000.0
//	**       * An == rowid constraint:       cost=10.0
