These new settings are designed to enchance user privacy surrounding
groups. They allow groups to be configured so that users outside the
group cannot see the group, so that users in the group cannot see each
other, or so that users cannot see the group at all, even if they are in
it. This avoids issues where a group may be assigned based on sensitive
personal information (such as a person requiring special arrangements
due to a disability).
By default, groups are visible to all and available for participation in
activities, which maintains the current behaviour.
For performance, a new cache has been added to track the number of
groups on a course that are not visible to non-members. This allows us
to revert to the existing behaviour if the new features are not being
used at all on a course, and only apply the new visibility conditions if
they are.
Users who have the moodle/course:viewhiddengroups capability should be
concious of exposing hidden groups when showing their screen to other
users. The "Switch role to..." feature can be used to show a course page
on screen without exposing private availability conditions, for example.
The changes cover several specific areas:
* grouplib functions, which most code should use to get lists of groups
and members (this includes the participants page).
* Activities supporting group overrides will not allow overrides for
groups that are hidden from all users.
* Activities supporting separate/visible groups modes will only allow
groups with the new "participation" flag enabled to be selected.
* Group messaging will be disabled for groups where members cannot see
each other, or cannot see the group at all.
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:
- The following task tests have been moved within the level2 directory:
- \core\adhoc_task_test => \core\task\adhoc_task_test
- \core\scheduled_task_test => \core\task\scheduled_task_test
- \core\calendar_cron_task_test => \core\task\calendar_cron_task_test
- \core\h5p_get_content_types_task_test => \core\task\h5p_get_content_types_task_test
- \core\task_database_logger_test => \core\task\database_logger_test
- \core\task_logging_test => \core\task\logging_test
- The following event tests have been moved within level2 directory:
- \core\event_context_locked_test => \core\event\context_locked_test
- \core\event_deprecated_test => \core\event\deprecated_test
- \core\event_grade_deleted_test => \core\event\grade_deleted_test
- \core\event_profile_field_test => \core\event\profile_field_test
- \core\event_unknown_logged_test => \core\event\unknown_logged_test
- \core\event_user_graded_test => \core\event\user_graded_test
- \core\event_user_password_updated_test => \core\event\user_password_updated_test
- The following output tests have been moved within level2 directory:
- \core\mustache_template_finder_test => \core\output\mustache_template_finder_test
- \core\mustache_template_source_loader_test => \core\output\mustache_template_source_loader_test
- \core\output_mustache_helper_collection_test => \core\output\mustache_helper_collection_test
- The following tests have been moved to their correct tests directories:
- lib/tests/time_splittings_test.php => analytics/tests/time_splittings_test.php
- All the classes and tests under lib/filebrowser and lib/filestorage
belong to core, not to core_files. Some day we should move
them to their correct subsystem.
- All the classes and tests under lib/grade belong to core, not
to core_grades. Some day we should move them to their correct
subsystem.
- The core_grades_external class and its \core\grades_external_test
unit test should belong to the grades subsystem or, alternatively,
to \core\external, they both should be moved together.
- The core_grading_external class and its \core\grading_external_test
unit test should belong to the grading subsystem or, alternatively,
to \core\external, they both should be moved together.
- The \core\message\message and \core\message\inbound (may be others)
classes, and their associated tests should go to the core_message
subsystem.
- The core_user class, and its associated tests should go to the
core_user subsystem.
- The \core\update namespace is plain wrong (update is not valid API)
and needs action 1) create it or 2) move elsewhere.
The methods assertContains() and assertNotContains() now perform
strict (type and value) comparison, pretty much like assertSame()
does.
A couple of new assertContainsEquals() and assertNotContainsEquals()
methods have been created to provide old (non-strict) behavior, pretty
much like assertEquals() do.
Apart from replacing the calls needing a relaxed comparison to those
new methods, there are also a couple of alternative, about how to
fix this, depending of every case:
- If the test is making any array_values() conversion, then it's better
to remove that conversion and use assertArrayHasKey(), that is not
strict.
- Sometimes if may be also possible to, simply, cast the expectation
to the exact type coming in the array. I've not applied this technique
to any of the cases in core.

The optional parameters of assertEquals() and assertNotEquals()
are deprecated in PHPUnit 8 (to be removed in PHPUnit 9):
- delta => use assertEqualsWithDelta()
- canonicalize => use assertEqualsCanonicalizing()
- ignoreCase => use assertEqualsIgnoringCase
- maxDepth => removed without replacement.
More info @ https://github.com/sebastianbergmann/phpunit/issues/3341
Initial search done with:
ag 'assert(Not)?Equals\(.*,.*,' --php
Then, running tests and fixing remaining cases.
Both assertContains() and assertNotContains() are deprecated in PHPUnit 8
for operations on strings. Also the optional case parameter is. All uses
must be changed to one of:
- assertStringContainsString()
- assertStringContainsStringIgnoringCase()
- assertStringNotContainsString()
- assertStringNotContainsStringIgnoringCase()
More info: https://github.com/sebastianbergmann/phpunit/issues/3422
Regexp to find all uses:
ag 'assert(Not)?Contains\('
These function updates are in preparation for the participants_search
class, which will be used to support multiple values per filter when
filtering the participants page.
A new optional parameter $context has been added to the
core_group::groups_get_members_join() function.
Besides, some core_group methods now accept -1 (USERSWITHOUTHGROUP) for
the groupid field.
Refactor similar SQL generation code from get_users_by_capability
and get_enrolled_uses to make get_with_capability_sql.
Modified files: accesslib.php, enrollib.php, grouplib.php, new tests.
