Hello there.
We are trying to troubleshoot our cron.php problem and would like to know where I can get more detailed info somewhere about all the tasks (in our case 85 of them) and what these tasks do and what tables they query and the logic behind them
Specifically.
- What is a "component" and what is its functions? (need more info to understand other than just "The component this scheduled task belongs to.")?
- What is the role of the "classname" (more info to understand other than " The class extending scheduled_task to be called when running this task.")?
- What is "blocking" and when is that triggered to changed its value?
- What is "faildelay" and when does that happen and what is recorded when something fails and how do we know what has failed?
- What is "customized" (more info other than "Used on upgrades to prevent overwriting custom schedules.") how does it work?
And all the task list shown.. more detail info on what each task does would be extremely useful in understanding them and what their limitations or conditions are.
for example: the one I really need to look at is: \\core\\task\\question_cron_task
| \\enrol_flatfile\\task\\flatfile_sync_task |
