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.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.x/tutorials/crontrigger.html - -The original version of this package included an optional "seconds" field, which -made it incompatible with both of these formats.

"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.SecondOptional | cron.Hour | cron.Dom | cron.Month | cron.Dow | cron.Descriptor)) - -The most popular alternative Cron expression format is Quartz: -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 - -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 / Chain - -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. -*/ -package cron diff --git a/vendor/github.com/robfig/cron/v3/go.mod b/vendor/github.com/robfig/cron/v3/go.mod deleted file mode 100644 index 8c95bf4..0000000 --- a/vendor/github.com/robfig/cron/v3/go.mod +++ /dev/null @@ -1,3 +0,0 @@ -module github.com/robfig/cron/v3 - -go 1.12 diff --git a/vendor/github.com/robfig/cron/v3/logger.go b/vendor/github.com/robfig/cron/v3/logger.go deleted file mode 100644 index b4efcc0..0000000 --- a/vendor/github.com/robfig/cron/v3/logger.go +++ /dev/null @@ -1,86 +0,0 @@ -package cron - -import ( - "io/ioutil" - "log" - "os" - "strings" - "time" -) - -// DefaultLogger is used by Cron if none is specified. -var DefaultLogger Logger = PrintfLogger(log.New(os.Stdout, "cron: ", log.LstdFlags)) - -// DiscardLogger can be used by callers to discard all log messages. -var DiscardLogger Logger = PrintfLogger(log.New(ioutil.Discard, "", 0)) - -// Logger is the interface used in this package for logging, so that any backend -// can be plugged in.
