Parameters

array $params

Member Function Documentation

◆ ack()

JobQueue::ack ( Job $job )

final

Acknowledge that a job was completed.

This does nothing for certain queue classes or if "claimTTL" is not set. Outside callers should use JobQueueGroup::ack() instead of this function.

Parameters

Job $job

Returns: void

Exceptions

JobQueueError

Definition at line 400 of file JobQueue.php.

Referenced by ack(), batchPush(), deduplicateRootJob(), delete(), and pop().

◆ batchPush()

JobQueue::batchPush	(	array	$jobs,
			$flags = `0`
	)

final

Push a batch of jobs into the queue.

This does not require $wgJobClasses to be set for the given job type. Outside callers should use JobQueueGroup::push() instead of this function.

Parameters

IJobSpecification[]	$jobs
int	$flags	Bitfield (supports JobQueue::QOS_ATOMIC)

Returns: void

Exceptions

JobQueueError

◆ deduplicateRootJob()

JobQueue::deduplicateRootJob ( IJobSpecification $job )

final

Register the "root job" of a given job into the queue for de-duplication.

This should only be called right after all the new jobs have been inserted. This is used to turn older, duplicate, job entries into no-ops. The root job information will remain in the registry until it simply falls out of cache.

This requires that $job has two special fields in the "params" array:

rootJobSignature : hash (e.g. SHA1) that identifies the task
rootJobTimestamp : TS_MW timestamp of this instance of the task

A "root job" is a conceptual job that consist of potentially many smaller jobs that are actually inserted into the queue. For example, "refreshLinks" jobs are spawned when a template is edited. One can think of the task as "update links of pages that use template X" and an instance of that task as a "root job". However, what actually goes into the queue are range and leaf job subtypes. Since these jobs include things like page ID ranges and DB master positions, and can morph into smaller jobs recursively, simple duplicate detection for individual jobs being identical (like that of job_sha1) is not useful.

In the case of "refreshLinks", if these jobs are still in the queue when the template is edited again, we want all of these old refreshLinks jobs for that template to become no-ops. This can greatly reduce server load, since refreshLinks jobs involves parsing. Essentially, the new batch of jobs belong to a new "root job" and the older ones to a previous "root job" for the same task of "update links of pages that use template X".

This does nothing for certain queue classes.

◆ factory()

static JobQueue::factory ( array $params )

staticfinal

Get a job queue object of the specified type.

$params includes:

class : What job class to use (determines job type)
domain : Database domain ID of the wiki the jobs are for (defaults to current wiki)
type : The name of the job types this queue handles
order : Order that pop() selects jobs, one of "fifo", "timestamp" or "random". If "fifo" is used, the queue will effectively be FIFO. Note that job completion will not appear to be exactly FIFO if there are multiple job runners since jobs can take different times to finish once popped. If "timestamp" is used, the queue will at least be loosely ordered by timestamp, allowing for some jobs to be popped off out of order. If "random" is used, pop() will pick jobs in random order. Note that it may only be weakly random (e.g. a lottery of the oldest X). If "any" is choosen, the queue will use whatever order is the fastest. This might be useful for improving concurrency for job acquisition.
claimTTL : If supported, the queue will recycle jobs that have been popped but not acknowledged as completed after this many seconds. Recycling of jobs simply means re-inserting them into the queue. Jobs can be attempted up to three times before being discarded.
readOnlyReason : Set this to a string to make the queue read-only.
stash : A BagOStuff instance that can be used for root job deduplication
stats : A StatsdDataFactoryInterface [optional]

Queue classes should throw an exception if they do not support the options given.

◆ isEmpty()

JobQueue::isEmpty ( )

final

Quickly check if the queue has no available (unacquired, non-delayed) jobs.

Queue classes should use caching if they are any slower without memcached.

If caching is used, this might return false when there are actually no jobs. If pop() is called and returns false then it should correct the cache. Also, calling flushCaches() first prevents this. However, this affect is typically not distinguishable from the race condition between isEmpty() and pop().
