The short name of the cc licenses are trailed with a suffix containing
the version number (current 3.0 and 4.0). The old cc* licenses become
the new cc-*-3.0 licenses and are disables, because the new cc*-4.0
licenses are the current ones.
This is a backport of MDL-43195.
If a statically accelerated cache returns an empty array then the value
was still fetched from the non-static cache store.
The check of the `$result` should be strictly checked against `false`,
which is the value used if no value was found.
If a plugin attempts to do something that would lock coursemodinfo cache
during install (such as creating a course module), this currently fails
as check_lock_state is not implemented in cache_disabled. Adding the
cache_loader_with_locking interface ensures that all lock methods are
implemented.
The feature added in 4.1 to lock the modinfo cache does not work when
using Redis, because:
* The API to acquire a cache lock is confusing, and the code did not
check that it successfully acquired a lock before going on to build
the cache anyway.
* Unlike the other types of cache lock, the Redis store did not retry
the lock for a timeout period before giving up and failing.
This change fixes both points.
Replaced 4 occurrences of get_debug_type() by gettype() to keep PHP 7.4 compatibility. Note this
has not been applied to 4.2dev and up because, there, it's safe to use get_debug_type().
Cache locking fails if the cache store supports multiple identifiers
(in core, the only two which do are cachestore_static and
cachestore_mongodb, so this is unlikely to cause severe problems).
The new library version should work without problems with older
php-mongodb extension versions:
- v1.15.0 (paired version, tested).
- v1.14.1 (tested)
So, here, in 401_STABLE, we aren't raising the requirements. We have
done that in master, in order to get php82 support, but not here. For
more details about compatibilities, see:
https://www.mongodb.com/docs/drivers/php/#compatibility
This updates the library from v1.13.1. Fixes some php81 warnings
leading to failed/risky tests.

In some cases, we get an error message such as:
Wrong parameter count for Redis::zRem()
Within the delete_many function. This function requires at least one
key to be supplied, but if delete_many is called with an empty array,
we will call it with no keys.
The cache file is only ever written to in the `write_file` function,
where it does so by writing to a temp file and performing an atomic
rename of that file. When writing, the target file is never locked.
The cache file is only ever read in the `get` function, and there is no
need for an exclusive lock in that situation.
There is therefore no need to obtain any lock, shared or exclusive, to
read the cache file. Doing so only affects performance of the file sytem
as file locks must be needlessly obtained and written to disk for a read
operation which does not benefit from them.
The Redis cache store and session handler both do a 'ping()' after
connecting to Redis. This is unnecessary because the connect() call
has just checked the network connection and it's hardly likely that
the server has gone down since then.
According to my profiling, both connect() and ping() take
measurable time when talking to a separate server, i.e. a few
milliseconds. So it's not the case that connect() doesn't really
talk to the server, as I initially wondered.
If using Redis on a separate (non-localhost) server for both session
and cache store, removing these ping calls can save a millisecond
or two per request.
Applied the following changes to various testcase classes:
- Namespaced with component[\level2-API]
- Moved to level2-API subdirectory when required.
- Fixed incorrect use statements with leading backslash.
- Remove file phpdoc block
- Remove MOODLE_INTERNAL if not needed.
- Changed code to point to global scope when needed.
- Fix some relative paths and comments here and there.
- All them passing individually.
- Complete runs passing too.
Special mention to:
- Some fixtures, initially defined in the test files have been
moved to new files in fixtures subdirectory, leaving the unit
test files clearer:
- moodle2_course_format_test.php
- Rename wrong named test:
- baseoptiogroup_test = baseoptigroup_test
When deleting a cache instance, it tried to purge it, even though
purge only makes sense for an individual definition (not the whole
instance). As a result, it errored.
This change includes addition of tests for verifying the secondary
and tertiary nav highlights.
It also includes the tests to verify the breadcrumbs for the pages.
Create or update the breadcrumbs in the site administration
pages where it is required.
Highlight the corresponding site adminstration tab.
Highlight the primary nav to Site administration when user
is navigating to any of the site administration pages.
Also changed the boostnavbar so that the nodes in the secondary
navigation are not shown in the breadcrumbs when user is in site
administration page.
