## [1.6.0] - 2022-10-13
|
||||
1.7.0 - 2023-10-22
|
||||
------------------
|
||||
This version of fsnotify needs Go 1.17.
|
||||
|
||||
### Additions
|
||||
|
||||
- illumos: add FEN backend to support illumos and Solaris. ([#371])
|
||||
|
||||
- all: add `NewBufferedWatcher()` to use a buffered channel, which can be useful
|
||||
in cases where you can't control the kernel buffer and receive a large number
|
||||
of events in bursts. ([#550], [#572])
|
||||
|
||||
- all: add `AddWith()`, which is identical to `Add()` but allows passing
|
||||
options. ([#521])
|
||||
|
||||
- windows: allow setting the ReadDirectoryChangesW() buffer size with
|
||||
`fsnotify.WithBufferSize()`; the default of 64K is the highest value that
|
||||
works on all platforms and is enough for most purposes, but in some cases a
|
||||
highest buffer is needed. ([#521])
|
||||
|
||||
### Changes and fixes
|
||||
|
||||
- inotify: remove watcher if a watched path is renamed ([#518])
|
||||
|
||||
After a rename the reported name wasn't updated, or even an empty string.
|
||||
Inotify doesn't provide any good facilities to update it, so just remove the
|
||||
watcher. This is already how it worked on kqueue and FEN.
|
||||
|
||||
On Windows this does work, and remains working.
|
||||
|
||||
- windows: don't listen for file attribute changes ([#520])
|
||||
|
||||
File attribute changes are sent as `FILE_ACTION_MODIFIED` by the Windows API,
|
||||
with no way to see if they're a file write or attribute change, so would show
|
||||
up as a fsnotify.Write event. This is never useful, and could result in many
|
||||
spurious Write events.
|
||||
|
||||
- windows: return `ErrEventOverflow` if the buffer is full ([#525])
|
||||
|
||||
Before it would merely return "short read", making it hard to detect this
|
||||
error.
|
||||
|
||||
- kqueue: make sure events for all files are delivered properly when removing a
|
||||
watched directory ([#526])
|
||||
|
||||
Previously they would get sent with `""` (empty string) or `"."` as the path
|
||||
name.
|
||||
|
||||
- kqueue: don't emit spurious Create events for symbolic links ([#524])
|
||||
|
||||
The link would get resolved but kqueue would "forget" it already saw the link
|
||||
itself, resulting on a Create for every Write event for the directory.
|
||||
|
||||
- all: return `ErrClosed` on `Add()` when the watcher is closed ([#516])
|
||||
|
||||
- other: add `Watcher.Errors` and `Watcher.Events` to the no-op `Watcher` in
|
||||
`backend_other.go`, making it easier to use on unsupported platforms such as
|
||||
WASM, AIX, etc. ([#528])
|
||||
|
||||
- other: use the `backend_other.go` no-op if the `appengine` build tag is set;
|
||||
Google AppEngine forbids usage of the unsafe package so the inotify backend
|
||||
won't compile there.

1.6.0 - 2022-10-13
|
||||
------------------
|
||||
This version of fsnotify needs Go 1.16 (this was already the case since 1.5.1,
|
||||
but not documented). It also increases the minimum Linux version to 2.6.32.

FAQ

### Will a file still be watched when it's moved to another directory?
|

No, not unless you are watching the location it was moved to.

### Are subdirectories watched too?
|
||||
### Are subdirectories watched?
|

No, you must add watches for any directory you want to watch (a recursive

watcher is on the roadmap: [#18]).

### Do I have to watch the Error and Event channels in a goroutine?
|
||||
As of now, yes (you can read both channels in the same goroutine using `select`,

you don't need a separate goroutine for both channels; see the example).

|

|
||||
### Why do I get many Chmod events?
|
||||
Some programs may generate a lot of attribute changes; for example Spotlight on
|
||||
macOS, anti-virus programs, backup applications, and some others are known to do
|
||||
this. As a rule, it's typically best to ignore Chmod events. They're often not
|
||||
useful, and tend to cause problems.
|
||||
|
||||
Spotlight indexing on macOS can result in multiple events (see [#15]). A
|
||||
temporary workaround is to add your folder(s) to the *Spotlight Privacy
|
||||
settings* until we have a native FSEvents implementation (see [#11]).

### Watching a file doesn't work well
|
||||
Watching individual files (rather than directories) is generally not recommended
|
||||
as many programs (especially editors) update files atomically: it will write to
|
||||
a temporary file which is then moved to to destination, overwriting the original
|
||||
(or some variant thereof). The watcher on the original file is now lost, as that
|
||||
no longer exists.
|
||||
|
||||
The upshot of this is that a power failure or crash won't leave a half-written
|
||||
file.
|
||||
|
||||
Watch the parent directory and use `Event.Name` to filter out files you're not
|
||||
interested in. There is an example of this in `cmd/fsnotify/file.go`.
