When we deprecate the use of a file, we often include tests which ensure
that the legacy behaviour is maintained. There are also legacy uses
in the community where people would like to use the deprecated API for a
period.
The issue that we face is that, if the deprecated file is included once,
then it will be included for all other, unrelated, tests. This means
that other tests may not detect cases where the deprecated file was
included.
We can solve these cases by running the test that performs the inclusion
in a deprecated process. This means that the inclusion is only performed
in that isolated process, and other unrelated tests do not include the
file.
However, we also then need to detect which files which are including the
file and which we do not know about.
This change introduces:
- an override to the TestCase::setInIsolation method to define a
constant when the test is running in isolation
- a new function that a file can call when it is included, to make sure
that the test process was isolated, where there is any test.
Apply the standard deprecation procedure to the old APIs, to
be removed in Moodle 4.2 (MDL-69882). Existing unit tests
cover the deprecation debugging.

This chagne adds support for a new feature known as Context Locking.
This allows a context to be locked, thereby removing all write
capabilities for all users (including admin) for that context, and all
child contexts.
- A new assertDebuggingCalledCount has been introduced, as multiple debugging messages
may be called in some cases, for example when calling events_cron with queued events
that need to be dispatched.
- events_update_definition has been moved out of setUp as debugging messages are only
caught by our phpunit custom stuff when they are called inside tests.
This patch replaces all homegrown timezone
stuff with standard PHP date/time code.
The main change is the introduction of core_date
class that returns normalised user and server
timezones. From now on nobody should be using
$CFG->timezone or $user->timezone directly!
Other new features and fixes:
* admins are prompted for timezone during install
* editing of other users is finally fixed
* timezones are displayed in user profile
* new $this->setTimezone() in phpunit
* time locale is now automatically reset in phpunit
* timezone is now automatically reset in phpunit
* phpunit has Australia/Perth as default timezone
List of changes:
* New OOP API using PHP namespace \core\session\.
* All handlers now update the sessions table consistently.
* Experimental DB session support in Oracle.
* Full support for session file handler (filesystem locking required).
* New option for alternative session directory.
* Official memcached session handler support.
* Workaround for memcached version with non-functional gc.
* Improved security - forced session id regeneration.
* Improved compatibility with recent PHP releases.
* Fixed borked CSS during install in debug mode.
* Switched to file based sessions in new installs.
* DB session setting disappears if DB does not support sessions.
* DB session setting disappears if session handler specified in config.php.
* Fast purging of sessions used in request only.
* No legacy distinction - file, database and memcached support the same functionality.
* Session handler name included in performance info.
* Fixed user_loggedin and user_loggedout event triggering.
* Other minor bugfixing and improvements.
* Fixed database session segfault if MUC disposed before $DB.
Limitations:
* Session access time is now updated right after session start.
* Support for $CFG->sessionlockloggedinonly was removed.
* First request does not update userid in sessions table.
* The timeouts may break badly if server hosting forces PHP.ini session settings.
* The session GC is a lot slower, we do not rely on external session timeouts.
* There cannot be any hooks triggered at the session write time.
* File and memcached handlers do not support session lock acquire timeouts.
* Some low level PHP session functions can not be used directly in Moodle code.
