Shapecode - Cron Bundle

This bundle provides a simple interface for registering repeated scheduled tasks within your application.

Install instructions

Installing this bundle can be done through these simple steps:

Add the bundle to your project through composer:

composer require shapecode/cron-bundle

Add the bundle to your config if it flex did not do it for you:

<?php

// config/bundles.php
return [
    // ...
    Shapecode\Bundle\CronBundle\ShapecodeCronBundle::class,
    // ...
];

Update your DB schema ...

... with Doctrine schema update method ...

php bin/console doctrine:schema:update --force

Creating your own tasks

Creating your own tasks with CronBundle couldn't be easier - all you have to do is create a normal Symfony2 Command (or ContainerAwareCommand) and tag it with the CronJob annotation, as demonstrated below:

<?php

declare(strict_types=1);

namespace App\DemoBundle\Command;

use Shapecode\Bundle\CronBundle\Annotation\CronJob;
use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;

/**
 * @CronJob("*\/5 * * * *")
 * Will be executed every 5 minutes
 */
class DemoCommand extends Command
{
    
    public function configure() : void
    {
		// Must have a name configured
		// ...
    }
    
    public function execute(InputInterface $input, OutputInterface $output) : void
    {
		// Your code here
    }
}

The interval spec ("*/5 * * * *" in the above example) use the standard cronjob schedule format and can be modified whenever you choose. You have to escape the / in this example because it would close the annotation. You can also register your command multiple times by using the annotation more than once with different values. For your CronJob to be scanned and included in future runs, you must first run php bin/console shapecode:cron:scan - it will be scheduled to run the next time you run php app/console shapecode:cron:run

Register your new Crons:

$ php bin/console shapecode:cron:scan
$ php bin/console shapecode:cron:run

Running your cron jobs automatically

This bundle is designed around the idea that your tasks will be run with a minimum interval - the tasks will be run no more frequently than you schedule them, but they can only run when you trigger then (by running bin/console shapecode:cron:run).

To facilitate this, you can create a cron job on your system like this:

*/5 * * * * php /path/to/symfony/bin/console shapecode:cron:run

This will schedule your tasks to run at almost every 5 minutes - for instance, tasks which are scheduled to run every 3 minutes will only run every 5 minutes.

Disabling and enabling individual cron jobs from the command line

This bundle allows you to easily disable and enable individual scheduled CronJobs from the command-line.

To disable a CronJob, run: bin/console shapecode:cron:edit your:cron:job --enable n, where your:cron:job is the name of the CronJob in your project you would like to disable.

Running the above will disable your CronJob until you manually enable it again. Please note that even though the next_run field on the cron_job table will still hold a datetime value, your disabled cronjob will not be run.

To enable a cron job, run: bin/console shapecode:cron:edit your:cron:job --enable y, where your:cron:job is the name of the CronJob in your project you would like to enable.

Config

By default, all cronjobs run until they are finished (or exceed the default timeout of 60s set by the Process component. When running cronjob from a controller, a timeout for running cronjobs can be useful as the HTTP request might get killed by PHP due to a maximum execution limit. By specifying a timeout, all jobs get killed automatically, and the correct job result (which would not indicate any success) will be persisted (see #26). A default value of null lets the Process component use its default timeout, otherwise the specified timeout in seconds (as float) is applied (see Process component docs). Important: The timeout is applied to every cronjob, regardless from where (controller or CLI) it is executed.

shapecode_cron:
    timeout: null # default. A number (of type float) can be specified
