>>> [!note] Migrated issue <!-- Drupal.org comment --> <!-- Migrated from issue #1072660. --> Reported by: [vertikal.dk](https://www.drupal.org/user/81257) >>> <p><b>Cron Debug 1.2 for Drupal 7.x</b></p> <p>Sandbox located here:<br> <a href="http://drupal.org/sandbox/vertikal.dk/1072626">http://drupal.org/sandbox/vertikal.dk/1072626</a></p> <p>Cron debug can run cron hooks while registering success and time elapsed for each. You can see which hooks will be run in which sequence, select which hooks to run and see their duration in the results as well as in the log.</p> <p>If a cron process times out, hangs or fails, you can see which ones finished successfully and which one did not finish properly by looking in the log when returning to Drupal's reports. All cron debug log entries are registered as "cron debug" and can be filtered separately. If the cron run failed, the usurper will be the top/last entry in the list of cron debug entries in the log.</p> <p>Notice that your regular cron jobs will run as usual if you have set them up. You might want to disable cron while debugging with cron debug. This module runs the cron jobs for each module separately from the usual cron run done in common.inc and invoked by cron.php.<br> Running cron.php will not register any debug code! You will have to run the cron debug routine to get this registration.</p> <p>Also notice that<br> * some modules have local settings, which enable and disable cron runs for that module. In such cases it will appear here as if the hook ran even though the function in the module might return without having done anything. In order to debug cron jobs in such modules, you will have to tamper with the module's own settings.<br> * some custom modules may call external functions and not return properly to Drupal in which case they may run as planned, but not register as finished in the log. Disable those jobs in order to have a smooth cron run, and (hopefully) a successful return to Drupal.</p> <p><b>Installation</b><br> Cron Debug can be installed like any other Drupal module -- place it in the modules directory for your site and enable it on the 'admin/build/modules' page.</p> <p>The module also exists in a D6-version, which will be added once I learn how to maintain several versions of a module.</p> <p><b>Why do I want to contribute a cron debug module to Drupal?</b><br> Well, because there is none, and the discussions about finding errors in cron runs are numerous and long, and solutions seem to employ all kinds of hacking and guesstimating. This module will put a bit of science into that equation and also deliver some hard evidence of slow routines or failures.<br> Like here <a href="http://drupal.org/cron">http://drupal.org/cron</a> and here <a href="http://drupal.org/node/123269">http://drupal.org/node/123269</a> and many other places.</p> <p><b>Who am I and what do I do?</b><br> I'm a professional Drupal developer in Denmark making my living developing in Drupal.<br> I develop full sites as well as custom modules and themes.<br> I contribute to the Drupal project with documentation and translation and also try to be active in the community by participating in events such as DrupalCons and local Drupal camps or days.</p> <p>I have done presentations and talks at several such events including DrupalCon Copenhagen.<br> <a href="http://www.archive.org/details/AddAMobileVersionToYourDrupalSite">http://www.archive.org/details/AddAMobileVersionToYourDrupalSite</a></p> <p>My work references are such as:<br> <a href="http://journalisten.dk/">http://journalisten.dk/</a> - main site of the Danish Journalist's union.<br> <a href="http://pressensuddannelsesfond.dk/">http://pressensuddannelsesfond.dk/</a> - application handling for the Danish press fund.<br> <a href="http://specialmedierne.dk/">http://specialmedierne.dk/</a> - web site for organization for Danish special media, magazines etc.<br> ...plus many others</p> <p>Hope that this makes the ball roll...</p> <p>And for the sake of confusion I add to this post the latest versions of the module with a few additions and edits - amongst those a hook_uninstall().</p> <p>Martin</p>
