For sites that rely on environment variables to set configuration,
ensure they are also present when executing task process.

It's better for the task to fail gracefully rather than silently
swallow any errors, so that the task API can schedule re-tries.
If the endpoint is temporarily down and/or misbehaving, this will
allow admins to have clearer failures.
The above syntax is defined as supported by the class, for example the
format '5/10' means:
"At every 10th <unit> from 5 through <max>."
It is analogous to '5-<max>/10'.
Previously, a set of calculated quiz statistics would only 'last' for
15 minutes. Then they would be considered invalid and not used.
Now, computed statistics are kept indefinitely. Instead, when a new
batch of values are computed for a particular set of settings, older numbers
for the same settings are deleted first. Therefore,
question_stats_cleanup_task is no more.
* CLI adhoc_task.php: new option --id
* cron::run_adhoc_task($taskid) for running tasks by id
* core\task\manager::get_adhoc_task($taskid) for retreival/locking
The enabled state of a plugin is a tri-state value (boolean or
null). We should be consistent with elsewhere by only considering
boolean false as an actually disabled plugin.
See also cdcb53a1 for similar change in task management.
Allow adhoc tasks to implement this method, so they too can have
descriptive names for themselves. Default implementation added to
return the class name itself.
This patch modifies the way copy data is shared in order to mitigate potential race conditions
and ensure that the serialised controller stored in the DB is always in a valid state.
The restore controller is now considered the "source of truth" for all information about the
copy operation. Backup controllers can no longer contain information about course copies.
As copy creation is not atomic, it is still possible for copy controllers to become orphaned or
exist in an invalid state. To mitigate this the backup cleanup task has been modified to call
a new helper method copy_helper::cleanup_orphaned_copy_controllers.
Summary of changes in this patch:
- Copy data must now be passed through the restore controller's constructor
- base_controller::get_copy has been deprecated in favour of restore_controller::get_copy
- base_controller::set_copy has been deprecated without replacement
- core_backup\copy\copy has been deprecated, use copy_helper.class.php's copy_helper instead
- backup_cleanup_task will now clean up orphaned controllers from copy operations that went awry
Thanks to Peter Burnett for assiting with testing this patch.
This patch changes the way adhoc tasks are chosen to run. It now calculates
how many runners each type of adhoc task should be allowed to use. In the
case that not all the runners are utilised, it attempts to infer which
tasks do not take a long time to run, and gives those to the vacant runners.
Thanks to Brendan Heywood for guidance and SQL help.
When "Path to PHP CLI" is not defined, an exception with the message
in cannotfindthepathtothecli should be displayed, and the page should
be redirected to System paths settings page.
Apart from that, this patch also replaced core_task to tool_task,
because this message wasn't traslated properly.
Use scheduled_task crontab field verification in
admin/tool/task to unify how Moodle deals with
crontab definition and its verification.
This helps remove duplicated code and fix
crontab definition not allowed in the web form,
but actually was valid.
Updated crontab fields precision on task_scheduled
table to have enough room for the worst case:
all possible different values separated by comma.
