Moodle Upgrade notes

This file contains important information for developers on changes to the Moodle codebase.

More detailed information on key changes can be found in the Developer update notes for your version of Moodle.

The format of this change log follows the advice given at Keep a CHANGELOG.

5.0dev

core

Added

  • The core/sortable_list Javascript module now emits native events, removing the jQuery dependency from calling code that wants to listen for the events. Backwards compatibility with existing code using jQuery is preserved

    For more information see MDL-72293

  • \core\output\activity_header now uses the is_title_allowed() method when setting the title in the constructor.

    This method has been improved to give priority to the 'notitle' option in the theme config for the current page layout, over the top-level option in the theme.

    For example, the Boost theme sets $THEME->activityheaderconfig['notitle'] = true; by default, but in its secure pagelayout, it has 'notitle' = false. This prevents display of the title in all layouts except secure.

    For more information see MDL-75610

  • The deprecated implementation in course/view.php, which uses the extern_server_course function to handle routing between internal and external courses, can be improved by utilizing the Hook API. This enhancement is essential for a project involving multiple universities, as the Hook API provides a more generalized and flexible approach to route users to external courses from within other plugins.

    For more information see MDL-83473

Changed

  • The {user_preferences}.value database field is now TEXT instead of CHAR. This means that any queries with a condition on this field in a WHERE or JOIN statement will need updating to use $DB->sql_compare_text(). See the $newusers query in \core\task\send_new_users_password_task::execute for an example.

    For more information see MDL-46739

  • All uses of the following PHPUnit methods have been removed as these methods are deprecated upstream without direct replacement:

    • withConsecutive
    • willReturnConsecutive
    • onConsecutive

    Any plugin using these methods must update their uses.

    For more information see MDL-81308

Deprecated

  • The methods want_read_slave and perf_get_reads_slave in lib/dml/moodle_database.php have been deprecated in favour of renamed versions that substitute slave for replica.

    For more information see MDL-71257

  • The trait moodle_read_slave_trait has been deprecated in favour of a functionally identical version called moodle_read_replica_trait. The renamed trait substitutes the terminology of slave with replica, and master with primary.

    For more information see MDL-71257

  • question_make_default_categories()

    No longer creates a default category in either CONTEXT_SYSTEM, CONTEXT_COURSE, or CONTEXT_COURSECAT. Superceded by question_get_default_category which can optionally create one if it does not exist.

    For more information see MDL-71378

  • question_delete_course()

    No replacement. Course contexts no longer hold question categories.

    For more information see MDL-71378

  • question_delete_course_category()

    Course category contexts no longer hold question categories.

    For more information see MDL-71378

  • The 'core_renderer::sr_text()' function has been deprecated, use 'core_renderer::visually_hidden_text()' instead.

Deprecated

  • The course_format_ajax_support function is now deprecated. Use course_get_format($course)->supports_ajax() instead.

    For more information see MDL-82351

core_courseformat

Added

  • A new core_courseformat\base::get_generic_section_name method is created to know how a specific format name the sections. This method is also used by plugins to know how to name the sections instead of using using a direct get_string on "sectionnamer" that may not exists.

    For more information see MDL-82349

  • Add core_courseformat\base::invalidate_all_session_caches to reset course editor cache for all users when course is changed. This method can be used as an alternative to core_courseformat\base::session_cache_reset for resetting the cache for the current user in case the change in the course should be reflected for all users.

    For more information see MDL-83185

core_enrol

Changed

  • The after_user_enrolled hook now contains a roleid property to allow for listeners to determine which role was assigned during user enrolment (if any)

    No replacement, not used anywhere in core.

    For more information see MDL-71378

core_reportbuilder

Added

  • New get_deprecated_tables method in base entity, to be overridden when an entity no longer uses a table (due to column/filter re-factoring, etc) in order to avoid breaking third-party reports

    For more information see MDL-78118

Changed

  • The get_active_conditions method of the base report class has a new $checkavailable parameter to determine whether to check the returned conditions availability

    For more information see MDL-82809

  • Report table instances no longer populate the countsql and countparams class properties. Instead calling code can access totalrows to obtain the same value, rather than manually counting via the prior properties

    For more information see MDL-83718

Removed

  • The following deprecated report entity elements have been removed:

    • comment:context
    • comment:contexturl
    • enrolment:method (plus enrolment formatter enrolment_name method)
    • 'enrolment:role`
    • file:context
    • file:contexturl
    • instance:context (tag)
    • instance:contexturl (tag)

    Use of the context table is also deprecated in the file and instance (tag) entities

    For more information see MDL-78118

  • Final removal of support for get_default_table_aliases method. Entities must now implement get_default_tables, which is now abstract, to define the tables they use

    For more information see MDL-82457

  • Remove mod_chat from Moodle 5.0

    For more information see MDL-82457

mod_assign

Fixed

  • The unit test for the privacy provider has been marked as final.

    A number of core tests had been incorrectly configured to extend this test but should instead be extending \mod_assign\tests\provider_testcase.

    Any community plugins extending the \mod_assign\privacy\provider_test test class should be updated to extend \mod_assign\tests\provider_testcase instead.

    For more information see MDL-81520

mod_feedback

Added

  • Added new mod_feedback_questions_reorder external function

    For more information see MDL-81745

    All shared functionality has been moved to a new autoloadable test-case: \mod_quiz\tests\attempt_walkthrough_testcase.

    To support this testcase the existing $files instance property should be replaced with a new static method, ::get_test_files. Both the existing instance property and the new static method can co-exist.

    For more information see MDL-81521

qbank_bulkmove

Deprecated

  • qbank_bulkmove/helper::get_displaydata

    Superceded by a modal and webservice, see qbank_bulkmove/modal_question_bank_bulkmove and core_question_external\move_questions

  • qbank_bulkmove\output\renderer::render_bulk_move_form

    Superceded by qbank_bulkmove\output\bulk_move

    For more information see MDL-71378

theme_boost

Removed

  • Remove chat and survey styles. Important note: the styles have been moved to the plugins as CSS files (and not SCSS) so themes might now need to override the mod_chat and mod_survey styles specifically as css does not have any definition for primary, gray and other colors accessible in the original scss version.

    For more information see MDL-82457

tool_brickfield

Deprecated

  • tool_brickfield\local\areas\core_question\answerbase::find_system_areas

    \core_component \core\component

    For more information see MDL-66903

  • Added the ability for unit tests to autoload classes in the \[component]\tests\ namespace from the [path/to/component]/tests/classes directory.

    For more information see MDL-66903

  • Added a helper to load fixtures from a components tests/fixtures/ folder:

    advanced_testcase::load_fixture(string $component, string $fixture): void;

  • Two new functions have been introduced in the \moodle_database class:

    • \moodle_database::get_counted_records_sql()
    • \moodle_database::get_counted_recordset_sql()

    These methods are compatible with all databases.

    They will check the current running database engine and apply the COUNT window function if it is supported, otherwise, they will use the usual COUNT function.

    The COUNT window function optimization is applied to the following databases:

    • PostgreSQL
    • MariaDB
    • Oracle

    Note: MySQL and SQL Server do not use this optimization due to insignificant performance differences before and after the improvement.

  • A new method, \core\output\::get_deprecated_icons(), has been added to the icon_system class. All deprecated icons should be registered through this method. Plugins can implement a callback to pluginname_get_deprecated_icons() to register their deprecated icons too. When $CFG->debugpageinfo is enabled, a console message will display a list of the deprecated icons.

    For more information see MDL-82212

  • Two new optional parameters have been added to the \core\output\notification constructor:

    • null|string $title - null|string $icon

    The following are examples of the new behaviour:

    Renderable name Renderer method name
    \core\output\action_menu\link render_action_menu__link
    \core\output\action_menu\link_primary render_action_menu__link_primary
