Important notice
We decided to move onto Symfony Messenger and we are therefore not maintaining this repository anymore. Feel free to fork it and make it your own.

Requirements
Note: it's necessary require the doctrine package in composer.json file.
Installation
Run composer require slm/queue-doctrine
.
If you have the laminas/laminas-component-installer package installed, it will ask you to enable the module (and SlmQueue
), both in Laminas and Mezzio. Otherwise, add the module to the list:
- in Laminas MVC, enable the module by adding
SlmQueueDoctrine
in your application.config.php file. - in Mezzio, enable the module by adding
SlmQueueDoctrine\ConfigProvider::class,
in your config.php file.
Note: Don't forget install SlmQueue in you config file, which is required.
Documentation
Before reading SlmQueueDoctrine documentation, please read SlmQueue documentation.
Configuring the connection
You need to register a doctrine connection which SlmQueueDoctrine will use to access the database into the service manager. Here are some examples.
Connection parameters can be defined in the application configuration:
<?php return [ 'doctrine' => [ 'connection' => [ // default connection name 'orm_default' => [ 'driverClass' => 'Doctrine\DBAL\Driver\PDOMySql\Driver', 'params' => [ 'host' => 'localhost', 'port' => '3306', 'user' => 'username', 'password' => 'password', 'dbname' => 'database', ] ] ] ], ];
Creating the table from SQL file
You must create the required table that will contain the queue's you may use the schema located in 'data/queue_default.sql'. If you change the table name look at Configuring queues
>mysql database < data/queue_default.sql
Creating the table from Doctrine Entity
There is an alternative way to create 'queue_default' table in your database by copying Doctrine Entity 'date/DefaultQueue.php' to your entity folder ('Application\Entity' in our example) and executing Doctrine's 'orm:schema-tool:update' command which should create the table for you. Notice that DefaultQueue entity is only used for table creation and is not used by this module internally.
Adding queues
return [ 'slm_queue' => [ 'queue_manager' => [ 'factories' => [ 'foo' => 'SlmQueueDoctrine\Factory\DoctrineQueueFactory' ] ] ] ];
Adding jobs
return [ 'slm_queue' => [ 'job_manager' => [ 'factories' => [ 'My\Job' => 'My\JobFactory' ] ] ] ];
Configuring queues
The following options can be set per queue ;
- connection (defaults to 'doctrine.connection.orm_default') : Name of the registered doctrine connection service
- table_name (defaults to 'queue_default') : Table name which should be used to store jobs
- deleted_lifetime (defaults to 0) : How long to keep deleted (successful) jobs (in minutes)
- buried_lifetime (defaults to 0) : How long to keep buried (failed) jobs (in minutes)
return [ 'slm_queue' => [ 'queues' => [ 'foo' => [ // ... ] ] ] ];
Provided Worker Strategies
In addition to the provided strategies by SlmQueue SlmQueueDoctrine comes with these strategies;
ClearObjectManagerStrategy
This strategy will clear the ObjectManager before execution of individual jobs. The job must implement the DoctrineModule\Persistence\ObjectManagerAwareInterface or SlmQueueDoctrine\Persistence\ObjectManagerAwareInterface.
listens to:
process.job
event at priority 1000
options:
- none
This strategy is enabled by default.
IdleNapStrategy
When no jobs are available in the queue this strategy will make the worker wait for a specific amount time before quering the database again.
listens to:
process.idle
event at priority 1
options:
nap_duration
defaults to 1 (second)
This strategy is enabled by default.
Operations on queues
push
Valid options are:
- scheduled: the time when the job will be scheduled to run next
- numeric string or integer - interpreted as a timestamp
- string parserable by the DateTime object
- DateTime instance
- delay: the delay before a job become available to be popped (defaults to 0 - no delay -)
- numeric string or integer - interpreted as seconds
- string parserable (ISO 8601 duration) by DateTimeInterval::__construct
- string parserable (relative parts) by DateTimeInterval::createFromDateString
- DateTimeInterval instance
- priority: the lower the priority is, the sooner the job get popped from the queue (default to 1024)
Examples:
// scheduled for execution asap $queue->push($job); // will get executed before jobs that have higher priority $queue->push($job, [ 'priority' => 200, ]); // scheduled for execution 2015-01-01 00:00:00 (system timezone applies) $queue->push($job, [ 'scheduled' => 1420070400, ]); // scheduled for execution 2015-01-01 00:00:00 (system timezone applies) $queue->push($job, [ 'scheduled' => '2015-01-01 00:00:00' ]); // scheduled for execution at 2015-01-01 01:00:00 $queue->push($job, [ 'scheduled' => '2015-01-01 00:00:00', 'delay' => 3600 ]); // scheduled for execution at now + 300 seconds $queue->push($job, [ 'delay' => 'PT300S' ]); // scheduled for execution at now + 2 weeks (1209600 seconds) $queue->push($job, [ 'delay' => '2 weeks' ]); // scheduled for execution at now + 300 seconds $queue->push($job, [ 'delay' => new DateInterval("PT300S")) ]);
Worker actions
Interact with workers from the command line from within the public folder of your Laminas Framework 2 application
Starting a worker
Start a worker that will keep monitoring a specific queue for jobs scheduled to be processed. This worker will continue until it has reached certain criteria (exceeds a memory limit or has processed a specified number of jobs).
vendor/bin/laminas slm-queue:start <queueName>
A worker will exit when you press cntr-C after it has finished the current job it is working on. (PHP doesn't support signal handling on Windows)
Recovering jobs
To recover jobs which are in the 'running' state for prolonged period of time (specified in minutes) use the following command.
vendor/bin/laminas slm-queue:doctrine:recover <queueName> [--executionTime=]
Note : Workers that are processing a job that is being recovered are NOT stopped.
