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 mutex
Yii Mutex
This package provides mutex implementation and allows mutual execution of concurrent processes in order to prevent "race conditions".
This is achieved by using a "lock" mechanism. Each possibly concurrent processes cooperates by acquiring a lock before accessing the corresponding data.
Requirements
- PHP 7.4 or higher.
Installation
The package could be installed with Composer:
General usage
There are multiple ways you can use the package. You can execute a callback in a synchronized mode i.e. only a single instance of the callback is executed at the same time:
Another way is to manually open and close mutex:
It could be done on lower level:
And if you want even more control, you can acquire mutex manually:
Mutex drivers
There are some mutex drivers available as separate packages:
If you want to provide your own driver, you need to implement MutexFactoryInterface and MutexInterface.
There is ready to extend Mutex, MutexFactory and a RetryAcquireTrait that contains retryAcquire()
method implementing the "wait for a lock for a certain time" functionality.
When implementing your own drivers, you need to take care of automatic unlocking. For example using a destructor:
and shutdown function:
Note that you should not call the exit() or die() functions in the destructor or shutdown function. Since calling
these functions in the destructor and shutdown function will prevent all subsequent completion functions from executing.
