* Makes it possible to safely call acquire_lock so that it throws an
exception instead of returning false if it can't get a lock (which
most existing uses assumed it already does).
* Fix some omissions from the requirelockingbeforewrite option (it
now checks on delete).
* Modinfo uses a versioned cache, so it is not necessary to delete
items, only increase the version. (Provided we keep track of
cacherev carefully...)
1. Modified the password related forms
2. Added a new constant in moodlelib.php called MAX_PASSWORD_CHARACTERS
3. Added a new method in moodlelib.php called exeeds_password_length
4. Updated the upgrade.text
Add a pepper to the users supplied password.
The pepper is stored in CFG and user to add extra security to
the password hash. By effectively breaking the information to
create the hashed password into two and storing it in more
than one place.
* Add parameter to drop zero time units. So a time interval like
"3d 0h 0s" will be returned as "3d" only.
* Add parameter to display full format for time units. E.g. Instead of
"3d 2h", it will be returned as "3 days 2 hours"
* Deprecate unused dateintervaldayshoursmins langconfig string.
Replace the bcrypt password hashing algorithm with SHA-512.
Existing bcrypt hashes will be updated to SHA-512 when a user
logs in next. Support for old md5 hashes has been removed.
Any reamining md5 hashes are replaced with SHA-512 hashes
from strong random passwords.
Since PHP 7.0 the random_bytes() is nativley available and Moodle
LMS requires greater than PHP 7, the native PHP funciton can be
used exclusively. Deprecating random_bytes_emulate.
* all constans usable in ABORT_AFTER_CONFIG should be always defined
* MDL_PERFDB and $PERF->logwrites not used after legacy log removal
* MDL_PERF_TEST should be documented in codebase
* deprecated warnings in shutdowb manager
New functions:
* `core_user::get_profile_picture` for retrieving user picture.
* `core_user::get_profile_url` for retrieving profile url.
* `core_user::get_fullname` for retrieving user full name.
Note: the context is not used as this stage. It will be used by "User Disguises" plugin, which will be implemented later.
This commit implements the communication api updates
when a user is updated. It handles the room membership
when a user is suspended and deleted.
Originally implemented as MDL-76703.

This commit implements the core communication api in the
core course to create or update matrix roomand its members
according to course settings. This commit will add the
communicaiton room in the course so that users can access
communication room from course.
Originally implemented as MDL-76702, MDL-76705 and MDL-76703.

With Moodle 4.1 and up, we have stopped to work with strftime(),
because it's deprecated for PHP 8.1 and up and, instead we are
using core_date::strftime() that performs the conversions using
the php-intl extension.
The original strftime() had a lot of OS-specific dependencies,
both about locale names and charsets used to provide the information.
Instead, the php-intl gets rid of all those OS-specific nightmares
and only uses ICU/Unicode locales and UTF-8.
Because of that, the old utf-8 => windows charset => utf-8
conversions aren't needed anymore. Hence, removing them.
At the moment, quiz_statistics\task\recalculate gives no useful
information about what it is doing, which makes it hard to investigate
if the task fails. This commit makes it more usefully verbose.
Also, following this change, one instance of this task will not
run for more than one hour at a time.
As part of this commit, I have added a new helper mtrace_exception.
to consistently log exceptions in scheduled tasks. It is sad to
add a new function to moodlelib.php, but that seemed the logical place.
Looking at other tasks, this method is badly needed. Many are just
logging the ->getMessage() which is normaly insufficient for proper
debugging. However, swiching all existing tasks to use the new function
will need to wait for a future MDL.
Default value of the $flag argument changed in PHP 8.1 from ENT_COMPAT to ENT_QUOTES | ENT_SUBSTITUTE
To ensure consistent behavior across different PHP version the second parameter is now required for the functions:
htmlspecialchars(), htmlentities(), htmlspecialchars_decode(), html_entity_decode() and get_html_translation_table()
This allows admins to configure whether contact site support is
available to everyone, authenticated users, or nobody.
The behat testing checks linked and direct access for each setting,
as well as adding testing that the support page override works as
expected.
