Detailed Description

Job for updating translation memory.

job params:

• command: the command to run, defaults to 'rebuild'
• service: the service to write to, if set to null the job will write to the default (primary) service and its replicas.
• errorCount: number of errors encountered while trying to perform the write on this service

This job handles retries itself and return false in allowRetries to disable JobQueue's internal retry service.

If mirroring is activated on the primary service then the first job will try to write to all services, it will resend a new job to every single service that failed and will increment errorCount. When too many errors occur on single service the job is dropped.

allowRetries()

TTMServerMessageUpdateJob::allowRetries

(

)

@inheritDoc

backoffDelay()

static TTMServerMessageUpdateJob::backoffDelay ( $errorCount )

static

Parameters

int

$errorCount

The number of times the job has errored out.

Returns

int Number of seconds to delay. With the default minimum exponent of 6 the possible return values are 64, 128, 256, 512 and 1024 giving a maximum delay of 17 minutes.

getHandle()

TTMServerMessageUpdateJob::getHandle ( )

protected

Extracted for testing purpose.

Returns

MessageHandle

getTranslation()

TTMServerMessageUpdateJob::getTranslation ( MessageHandle $handle )

protected

Extracted for testing purpose.

Parameters

MessageHandle

$handle

Returns

string

newJob()

static TTMServerMessageUpdateJob::newJob ( MessageHandle $handle, $command )

static

Parameters

MessageHandle	$handle
string	$command

Returns

self

resend()

TTMServerMessageUpdateJob::resend ( self $job )

protected

Extracted for testing purpose.

Parameters

self

$job

Definition at line 202 of file TTMServerMessageUpdateJob.php.

run()

TTMServerMessageUpdateJob::run

(

)

Fetch all the translations and update them.

Returns

bool

Definition at line 82 of file TTMServerMessageUpdateJob.php.

setDelay()

TTMServerMessageUpdateJob::setDelay

(

$delay

)

Set a delay for this job.

Note that this might not be possible, the JobQueue implementation handling this job doesn't support it (JobQueueDB) but is possible for the high performance JobQueueRedis. Note also that delays are minimums - at least JobQueueRedis makes no effort to remove the delay as soon as possible after it has expired. By default it only checks every five minutes or so. Note yet again that if another delay has been set that is longer then this one then the longer delay stays.

Parameters

int

$delay

seconds to delay this job if possible

const TTMServerMessageUpdateJob::WRITE_BACKOFF_EXPONENT = 7

protected

Constant used by backoffDelay().

With 7 the cumulative delay between the first and last attempt is between 8 and 33 minutes.
