[Extension] Crontab

Yii 1.1 Extensions
1

I just created a extension to manage system cron jobs with Yii that can also be used to run Application console commands.

http://www.yiiframework.com/extension/yii-crontab/

2

just release version 0.3

Previous jobs are now retrieve from crontab file for further modifications and stuff…

Looks nice. :) Two notes:

  • You should better use __construct() as constructor name.

  • Maybe add a comment, that the crontab file must be writeable for the webserver if you want to manage jobs through a webinterface. This should be a well considered decision, as it can open up a huge security hole.

Crontab file access is based upon user permission. If user is wwwuser1, the extension creates a crontab file(typically, this is just a normal text file) for that user in the directory of this extension and then use ‘crontab file’ unix command to load the jobs in system crontab for that user. I guess there shouldn’t be any security holes.

I’m going to try to use it for my current project :)

Can you please add other documentation?

I’ve extracted everything under the folder extensions, but when you try to do


$cron = new Crontab('my_crontab'); // my_crontab file will store all added jobs

It will exit with this error:




PHP Error

In the usage guide document (http://www.yiiframework.com/extension/yii-crontab) has code lines


Usage


See the following code example:


// Usage with ApplicationConsole and normal jobs

 

    $cron = new Crontab('my_crontab'); // my_crontab file will store all added jobs

 

    $jobs_obj = $cron->getJobs(); // previous jobs saved in my_crontab

 

    foreach($jobs_obj as $job)

        echo $job->getCommand();

 

    $cron->eraseJobs(); // erase all previous jobs in my_crontab

 

    // Application console job

    $cron->addApplicationJob('yiicmd', 'test1', array(), '*');

 

    // to change job values:

    $jobs_obj = $cron->getJobs();

    $jobs_obj[0]->setParams(array("'datetime'"));

    $jobs_obj[0]->setCommandName('test');

 

    // <= adds a job with: * * * * * php /home/user/my_project/www/yiicmd.php test 'datetime'

 

    // add an other job

    $job = new CronApplicationJob('yiicmd', 'test', array("'datetime"), '0', '0'); // run every day

    $job->setParams(array("'date'"));

    $cron->add($job);

 

    // <= adds a second job with: 0 0 * * * php /home/user/my_project/www/yiicmd.php test 'date'

 

    // add a regular cron job

    $cron->addJob('/home/user/myprogram.bin', '0', '0', '*', '*', '1'); // run every monday

    $jobs_obj = $cron->getJobs();

    echo $jobs_obj[2]->getCommand();

 

    // <= adds a third job with: 0 0 * * 1 /home/user/myprogram.bin 

 

    $cron->removeJob(2); // removes job with offset 2 (last added here)

 

    $cron->saveCronFile(); // save to my_crontab cronfile

 

    $cron->saveToCrontab(); // adds all my_crontab jobs to system (replacing previous my_crontab jobs)

I don’t know where is php file to put these code lines? Please help me

thanks
