SymfonyPIDManager
=================

[](#symfonypidmanager)

Description
-----------

[](#description)

This bundle is intended to prevent running a command twice at the same time.

When you spool your mails for an example with an cronjob and have a huge amount of mails, it could otherwise happen that the old instance is still sending emails while starting the command a second time.

\###Function The functionality is kept simple. Before executing a command this PIDManager writes the current pid (process id) into a configured file(pid\_path). Before running a second time it will check this file and return if the process is still running.

\###Warning This Bundle currently only works on Linux, because it detects running processes over the procfs (/proc/$pid).

Usage
-----

[](#usage)

\###With Symfony2

AppKernel.php add the following lines

```
new TuxCoder\PIDManagerBundle\PIDManagerBundle(),

```

config.yml add the following lines

```
pid_manager:
  commands:
    - name: swiftmailer:spool:send
      pid_path: /run/user/symfony/mail_spool.pid
    - name: secoundCommandName
      pid_path: /path/to/otherPidFile.pid

```

\###Without Symfony2 $pidManager=new \\TuxCoder\\PIDManagerBundle\\PIDManager(); $pidManager->setPidPath('/path/to/pid/file'); if(!$pidManager->isRunning()) { $pidManager->setRunning();

```
  //do some cool stuff

  $pidManager->setNotRunning();
} else {
  //error program is running
}

```

TODO
----

[](#todo)

- Write some Tests
- Add an event handler for "AllreadyRunningException".
- If requested also make it runnable on Windows, Mac, BSD....
