FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package simple-job-queue
Simple PHP Job Queue
I wanted/needed a simple job queue that could be used on a database, but also used with other adapters like beanstalkd/redis/etc if needed. Didn't really see a good option for a standalone job queue for a database.
Install
Requirements: PHP 7.4 or higher.
Note on Beanstalkd: The
pda/pheanstalkpackage is only needed if you use the Beanstalkd adapter. It is listed undersuggestincomposer.json(not a hard requirement) so pure database users are not forced to install it.
Usage
In order for this to work, you need a way to add jobs to the queue and a way to process the jobs (a worker). Below are examples of how to add a job to the queue and how to process the job.
Adding a new job
MySQL
PostgreSQL
SQLite3
Beanstalkd
Running a worker
See example_worker.php for file or see below:
Handling long processes
Supervisord is going to be your jam. Look up the many, many articles on how to implement this.
Configurable options
Several behaviors can be tuned via the $options array passed to the constructor (or setOptions()):
stale_timeout(int, seconds): How long to wait before a reserved job is considered "stale" and can be re-claimed by another worker (DB backends only). Default:300(5 minutes). This default preserves the historical behavior exactly.
Example:
Additional methods (additive, non-breaking)
New methods have been added that do not change any existing behavior:
releaseJob($job)— Un-reserves a job that was previously obtained viagetNextJobAndReserve(), making it available again immediately (useful if processing was abandoned).getReadyCount(?string $pipeline = null): intgetBuriedCount(?string $pipeline = null): int
These work for all supported backends. Pass a pipeline name to query a specific one, or omit to use the currently selected pipeline.
See the source or tests for usage examples. All new functionality follows the same "select/watch pipeline + connection" contract as the rest of the library.
Testing
PHPUnit Tests with sqlite3 examples for the time being.
