[performance] processing media and scheduled jobs improvements (#1482)

Browse source 
* replace media workers with just runners.WorkerPool, move to state structure, use go-sched for global task scheduling

* improved code comment

* fix worker tryUntil function, update go-runners/go-sched

* make preprocess functions package public, use these where possible to stop doubled up processing

* remove separate emoji worker pool

* limit calls to time.Now() during media preprocessing

* use Processor{} to manage singular runtime of processing media

* ensure workers get started when media manager is used

* improved error setting in processing media, fix media test

* port changes from processingmedia to processing emoji

* finish code commenting

* finish code commenting and comment-out client API + federator worker pools until concurrency worker pools replaced

* linterrrrrrrrrrrrrrrr

# cron
Cron V3 has been released!
To download the specific tagged release, run:
go get github.com/robfig/cron/v3@v3.0.0
Import it in your program as:
import "github.com/robfig/cron/v3"
It requires Go 1.11 or later due to usage of Go Modules.
Refer to the documentation here:
http://godoc.org/github.com/robfig/cron
The rest of this document describes the the advances in v3 and a list of
breaking changes for users that wish to upgrade from an earlier version.
## Upgrading to v3 (June 2019)
cron v3 is a major upgrade to the library that addresses all outstanding bugs,
feature requests, and rough edges. It is based on a merge of master which
contains various fixes to issues found over the years and the v2 branch which
contains some backwards-incompatible features like the ability to remove cron
jobs. In addition, v3 adds support for Go Modules, cleans up rough edges like
the timezone support, and fixes a number of bugs.
New features:
- Support for Go modules. Callers must now import this library as
`github.com/robfig/cron/v3`, instead of `gopkg.in/...`
- Fixed bugs:
- 0f01e6b parser: fix combining of Dow and Dom (#70)
- dbf3220 adjust times when rolling the clock forward to handle non-existent midnight (#157)
- eeecf15 spec_test.go: ensure an error is returned on 0 increment (#144)
- 70971dc cron.Entries(): update request for snapshot to include a reply channel (#97)
- 1cba5e6 cron: fix: removing a job causes the next scheduled job to run too late (#206)
- Standard cron spec parsing by default (first field is "minute"), with an easy
way to opt into the seconds field (quartz-compatible). Although, note that the
year field (optional in Quartz) is not supported.
- Extensible, key/value logging via an interface that complies with
the https://github.com/go-logr/logr project.
- The new Chain & JobWrapper types allow you to install "interceptors" to add
cross-cutting behavior like the following:
- Recover any panics from jobs
- Delay a job's execution if the previous run hasn't completed yet
- Skip a job's execution if the previous run hasn't completed yet
- Log each job's invocations
- Notification when jobs are completed
It is backwards incompatible with both v1 and v2. These updates are required:
- The v1 branch accepted an optional seconds field at the beginning of the cron
spec. This is non-standard and has led to a lot of confusion. The new default
parser conforms to the standard as described by [the Cron wikipedia page].
UPDATING: To retain the old behavior, construct your Cron with a custom
parser:
// Seconds field, required
cron.New(cron.WithSeconds())
// Seconds field, optional
cron.New(
cron.WithParser(
cron.SecondOptional | cron.Minute | cron.Hour | cron.Dom | cron.Month | cron.Dow | cron.Descriptor))
- The Cron type now accepts functional options on construction rather than the
previous ad-hoc behavior modification mechanisms (setting a field, calling a setter).
UPDATING: Code that sets Cron.ErrorLogger or calls Cron.SetLocation must be
updated to provide those values on construction.
- CRON_TZ is now the recommended way to specify the timezone of a single
schedule, which is sanctioned by the specification. The legacy "TZ=" prefix
will continue to be supported since it is unambiguous and easy to do so.
UPDATING: No update is required.
- By default, cron will no longer recover panics in jobs that it runs.
Recovering can be surprising (see issue #192) and seems to be at odds with
typical behavior of libraries. Relatedly, the `cron.WithPanicLogger` option
has been removed to accommodate the more general JobWrapper type.
UPDATING: To opt into panic recovery and configure the panic logger:
cron.New(cron.WithChain(
cron.Recover(logger), // or use cron.DefaultLogger
))
- In adding support for https://github.com/go-logr/logr, `cron.WithVerboseLogger` was
removed, since it is duplicative with the leveled logging.
UPDATING: Callers should use `WithLogger` and specify a logger that does not
discard `Info` logs. For convenience, one is provided that wraps `*log.Logger`:
cron.New(
cron.WithLogger(cron.VerbosePrintfLogger(logger)))
### Background - Cron spec format
There are two cron spec formats in common usage:
- The "standard" cron format, described on [the Cron wikipedia page] and used by
the cron Linux system utility.
- The cron format used by [the Quartz Scheduler], commonly used for scheduled
jobs in Java software
[the Cron wikipedia page]: https://en.wikipedia.org/wiki/Cron
[the Quartz Scheduler]: http://www.quartz-scheduler.org/documentation/quartz-2.3.0/tutorials/tutorial-lesson-06.html
The original version of this package included an optional "seconds" field, which
made it incompatible with both of these formats. Now, the "standard" format is

/*
Package cron implements a cron spec parser and job runner.
Installation
To download the specific tagged release, run:
go get github.com/robfig/cron/v3@v3.0.0
Import it in your program as:
import "github.com/robfig/cron/v3"
It requires Go 1.11 or later due to usage of Go Modules.
Usage
Callers may register Funcs to be invoked on a given schedule. Cron will run
them in their own goroutines.
c := cron.New()
c.AddFunc("30 * * * *", func() { fmt.Println("Every hour on the half hour") })
c.AddFunc("30 3-6,20-23 * * *", func() { fmt.Println(".. in the range 3-6am, 8-11pm") })
c.AddFunc("CRON_TZ=Asia/Tokyo 30 04 * * *", func() { fmt.Println("Runs at 04:30 Tokyo time every day") })
c.AddFunc("@hourly", func() { fmt.Println("Every hour, starting an hour from now") })
c.AddFunc("@every 1h30m", func() { fmt.Println("Every hour thirty, starting an hour thirty from now") })
c.Start()
..
// Funcs are invoked in their own goroutine, asynchronously.
...
// Funcs may also be added to a running Cron
c.AddFunc("@daily", func() { fmt.Println("Every day") })
..
// Inspect the cron job entries' next and previous run times.
inspect(c.Entries())
..
c.Stop() // Stop the scheduler (does not stop any jobs already running).
CRON Expression Format
A cron expression represents a set of times, using 5 space-separated fields.
Field name | Mandatory? | Allowed values | Allowed special characters
---------- | ---------- | -------------- | --------------------------
Minutes | Yes | 0-59 | * / , -
Hours | Yes | 0-23 | * / , -
Day of month | Yes | 1-31 | * / , - ?
Month | Yes | 1-12 or JAN-DEC | * / , -
Day of week | Yes | 0-6 or SUN-SAT | * / , - ?
Month and Day-of-week field values are case insensitive. "SUN", "Sun", and
"sun" are equally accepted.
The specific interpretation of the format is based on the Cron Wikipedia page:
https://en.wikipedia.org/wiki/Cron
Alternative Formats
Alternative Cron expression formats support other fields like seconds. You can
implement that by creating a custom Parser as follows.
cron.New(
cron.WithParser(
cron.NewParser(
cron.SecondOptional | cron.Minute | cron.Hour | cron.Dom | cron.Month | cron.Dow | cron.Descriptor)))
Since adding Seconds is the most common modification to the standard cron spec,
cron provides a builtin function to do that, which is equivalent to the custom
parser you saw earlier, except that its seconds field is REQUIRED:
cron.New(cron.WithSeconds())
That emulates Quartz, the most popular alternative Cron schedule format:
http://www.quartz-scheduler.org/documentation/quartz-2.x/tutorials/crontrigger.html
Special Characters
Asterisk ( * )
The asterisk indicates that the cron expression will match for all values of the
field; e.g., using an asterisk in the 5th field (month) would indicate every
month.
Slash ( / )
Slashes are used to describe increments of ranges. For example 3-59/15 in the
1st field (minutes) would indicate the 3rd minute of the hour and every 15
minutes thereafter. The form "*\/..." is equivalent to the form "first-last/...",
that is, an increment over the largest possible range of the field. The form
"N/..." is accepted as meaning "N-MAX/...", that is, starting at N, use the
increment until the end of that specific range. It does not wrap around.
Comma ( , )
Commas are used to separate items of a list. For example, using "MON,WED,FRI" in
the 5th field (day of week) would mean Mondays, Wednesdays and Fridays.
Hyphen ( - )
Hyphens are used to define ranges. For example, 9-17 would indicate every
hour between 9am and 5pm inclusive.
Question mark ( ? )
Question mark may be used instead of '*' for leaving either day-of-month or
day-of-week blank.
Predefined schedules
You may use one of several pre-defined schedules in place of a cron expression.
Entry | Description | Equivalent To
----- | ----------- | -------------
@yearly (or @annually) | Run once a year, midnight, Jan. 1st | 0 0 1 1 *
@monthly | Run once a month, midnight, first of month | 0 0 1 * *
@weekly | Run once a week, midnight between Sat/Sun | 0 0 * * 0
@daily (or @midnight) | Run once a day, midnight | 0 0 * * *
@hourly | Run once an hour, beginning of hour | 0 * * * *
Intervals
You may also schedule a job to execute at fixed intervals, starting at the time it's added
or cron is run. This is supported by formatting the cron spec like this:
@every <duration>
where "duration" is a string accepted by time.ParseDuration
(http://golang.org/pkg/time/#ParseDuration).
For example, "@every 1h30m10s" would indicate a schedule that activates after
1 hour, 30 minutes, 10 seconds, and then every interval after that.
Note: The interval does not take the job runtime into account. For example,
if a job takes 3 minutes to run, and it is scheduled to run every 5 minutes,
it will have only 2 minutes of idle time between each run.
Time zones
By default, all interpretation and scheduling is done in the machine's local
time zone (time.Local). You can specify a different time zone on construction:
cron.New(
cron.WithLocation(time.UTC))
Individual cron schedules may also override the time zone they are to be
interpreted in by providing an additional space-separated field at the beginning
of the cron spec, of the form "CRON_TZ=Asia/Tokyo".
For example:
# Runs at 6am in time.Local
cron.New().AddFunc("0 6 * * ?", ...)
# Runs at 6am in America/New_York
nyc, _ := time.LoadLocation("America/New_York")
c := cron.New(cron.WithLocation(nyc))
c.AddFunc("0 6 * * ?", ...)
# Runs at 6am in Asia/Tokyo
cron.New().AddFunc("CRON_TZ=Asia/Tokyo 0 6 * * ?", ...)
# Runs at 6am in Asia/Tokyo
c := cron.New(cron.WithLocation(nyc))
c.SetLocation("America/New_York")
c.AddFunc("CRON_TZ=Asia/Tokyo 0 6 * * ?", ...)
The prefix "TZ=(TIME ZONE)" is also supported for legacy compatibility.
Be aware that jobs scheduled during daylight-savings leap-ahead transitions will
not be run!
Job Wrappers
A Cron runner may be configured with a chain of job wrappers to add
cross-cutting functionality to all submitted jobs. For example, they may be used
to achieve the following effects:
- Recover any panics from jobs (activated by default)
- Delay a job's execution if the previous run hasn't completed yet
- Skip a job's execution if the previous run hasn't completed yet
- Log each job's invocations
Install wrappers for all jobs added to a cron using the `cron.WithChain` option:
cron.New(cron.WithChain(
cron.SkipIfStillRunning(logger),
))
Install wrappers for individual jobs by explicitly wrapping them:
job = cron.NewChain(
cron.SkipIfStillRunning(logger),
).Then(job)
Thread safety
Since the Cron service runs concurrently with the calling code, some amount of
care must be taken to ensure proper synchronization.
All cron methods are designed to be correctly synchronized as long as the caller
ensures that invocations have a clear happens-before ordering between them.
Logging
Cron defines a Logger interface that is a subset of the one defined in
github.com/go-logr/logr. It has two logging levels (Info and Error), and
parameters are key/value pairs. This makes it possible for cron logging to plug
into structured logging systems. An adapter, [Verbose]PrintfLogger, is provided
to wrap the standard library *log.Logger.
For additional insight into Cron operations, verbose logging may be activated
which will record job runs, scheduling decisions, and added or removed jobs.
Activate it with a one-off logger as follows:
cron.New(
cron.WithLogger(
cron.VerbosePrintfLogger(log.New(os.Stdout, "cron: ", log.LstdFlags))))
Implementation
Cron entries are stored in an array, sorted by their next activation time. Cron
sleeps until the next job is due to be run.
Upon waking:
- it runs each entry that is active on that second
- it calculates the next run times for the jobs that were run
- it re-sorts the array of entries by next activation time.
- it goes to sleep until the soonest job.
