This patch includes refreshing of borked files in file pool and basic prevention of race conditions. It also helps with diagnosing of file pool permission problems, detects coding errors and some other type of problems including sha1 collision jackpot.
I have accidentally spotted this typo while working on this branch. It
has never caused any harm as both parameters callerurl and returnurl are
always passed. Blame copy/pasting of code blocks.
The method available_update_deployer::make_execution_widget() used to
have hard-coded return URL. Now it accepts the return URL as the second
parameter and passes it to the mdeploy.php utility.
The callerurl parameter is now correctly passed and used.
Not all add-ons require administrator's attention during the upgrade
now. They are now listed only if there is an update available for them.
Also, it's not true any more that add-ons must be updated manually. They
can be updated using the automatic deployment feature, too.
Plugins that are to be installed and plugins that are missing from disk
are now highlighted at the Plugins overview screen. Other statuses (such as
of plugin to be upgraded) should not be needed at this page as those
are primarily intended for the Plugins checks screen during the upgrade.
If the plugin has been only deployed to the disk without installing into
the database, do not allow going through the uninstallation procedure.
Not only it does not have much sense. But it can also lead to some
tricky situation due to dependencies. Better to block it and wait till
the plugin is either fully installed or removed from the disk.
The permissions check is not correct (even users with grade capability should not
see user identities) and $assignment->get_renderer() is preferred over $OUTPUT.
This change is a large change to the way sessions are handled
within MUC after it was discovered that session did not function
as expected when any store other than the default session store
was being used.
As part of this change the session loader has been largely
customised in order to consolidate session data for the loader.
The unit tests have also being greatly increased to provide
better coverage for sessions.
