Shutdown handlers are processed in order. If something in a shutdown
handler uses a file which is stored in a per-request directory, and
another, unrelated, per-request directory was created before the handler
started. then a fresh per-request directory will be required.
There is an existing warning if cron doesn't run at all (hasn't run
for 24 hours). This commit adds a warning if cron hasn't run for 3
minutes, based on the recommendation that cron should run every
minute.
Purge cache just for the current user to avoid redirection when 2
simultaneous users try to sign up at the same time and some policy
has to be agreed.
The 'createduser' invalidation event has been removed also because
is not used any more.
Thanks John Azinheira for spotting it!
Before this change the query examined at every course_module record in
the context table.
With this change we use the course_modules table to more efficiently
find all the activities in the course, which means that many less
records in the context table need to be examined.
When no value is set for an option element and a user selects it, a
POST request is made, which is incorrect. Usually that option is a
placeholder value, e.g., "Choose..." - the form expecting the end user
to choose an actual value.
Changed the template loading to buffer the requests for templates
so that they can be sent in batches to the server to save large
volumes of network requests.
Changed the getTemplate function in templates.js to use the
core_output_load_template_with_dependencies function to load the
requested template and all of the dependencies required to render it.
The dependencies are added to the relevant caches so that when the
template is rendered they aren't re-requested from the server.
3.7 (min PHP 7.1) requires 3.2 (first version supporting PHP 7.1)
This just deletes all the upgrade steps previous to 3.2.0. Some
small adjustments, like adding missing MOODLE_INTERNAL or tweaking
globals can also be applied when needed.
Also includes an upgrade step to prevent upgrading from any
version < 2016120500 (v3.2.0) as anti-cheating measure.
Next commit will get rid of/deprecate all the upgradelib functions
not used anymore in codebase. (note there isn't any this time).
