Functions that are not part of a class:
| cron_run() X-Ref |
| Execute cron tasks |
| cron_run_scheduled_tasks(int $timenow) X-Ref |
| Execute all queued scheduled tasks, applying necessary concurrency limits and time limits. param: int $timenow The time this process started. |
| cron_run_adhoc_tasks(int $timenow, $keepalive = 0, $checklimits = true) X-Ref |
| Execute all queued adhoc tasks, applying necessary concurrency limits and time limits. param: int $timenow The time this process started. param: int $keepalive Keep this function alive for N seconds and poll for new adhoc tasks. param: bool $checklimits Should we check limits? |
| cron_run_inner_scheduled_task(\core\task\task_base $task) X-Ref |
| Shared code that handles running of a single scheduled task within the cron. Not intended for calling directly outside of this library! param: \core\task\task_base $task |
| cron_run_inner_adhoc_task(\core\task\adhoc_task $task) X-Ref |
| Shared code that handles running of a single adhoc task within the cron. param: \core\task\adhoc_task $task |
| cron_set_process_title(string $title) X-Ref |
| Sets the process title This makes it very easy for a sysadmin to immediately see what task a cron process is running at any given moment. param: string $title process status title |
| cron_trace_time_and_memory() X-Ref |
| Output some standard information during cron runs. Specifically current time and memory usage. This method also does gc_collect_cycles() (before displaying memory usage) to try to help PHP manage memory better. |
| cron_prepare_core_renderer($restore = false) X-Ref |
