In PHP 8.2 and later, setting a value to an undeclared class property is
deprecated and emits a deprecation notice.
So we need to add missing class properties that still need to be declared.
When we read the MUC configuration, a file which exists but is empty
will not error, but will cause all configuration to be empty.
We already perform an {{is_array()}} check on the {{$configuration}}
variable, but the default value for {{$configuration}} is an empty
array. In the case where the file exists, but is empty, no errors occur
when the file is loaded, and the initial {{$configuration}} value is
not overwritten, leading to the file being replaced with an empty copy.
Issues:
1. Fix setType calls
2. Changing from default to all and editing again, default is still selected.
3. Uncheck all options causes error.
4. Doesn't seem to be restricting based upon option.
5. Picked all and got coding error with the database thing.
6. Bad title: https://github.com/samhemelryk/moodle/commit/wip-MDL-37500-m25#L1R157
7. Amend comments - should only be removed once 2.5 is the minimum version for an upgrade.
8. Document the defaultsharing option.
Outcomes:
1. Fixed - copy paste error.
2. Fixed - mforms was applying the default value despite a value being provided. A quirk of elements with array names.
3. Fixed - validation now requires at least one option to be selected.
4. Fixed - issue rose from definitions not being re-parsed. cache/admin.php now reparses the first time a user visits the page.
5. Fixed - better purging of definitions when working with them anonymously. Unit test added.
6. Fixed - new string added and used.
7. Fixed - comments amended.
New issue to address parsing of definitions during upgrade.
New issue to add debugging notice if definition sets only one possible sharing option and that option is user input.
Bug: There was no way to create an instance of a lock plugin for use
within Moodle.
Solution: Implemented management interfaces as part of cache/admin.php
to allow for instances to be added and deleted.
This was done in along the same lines of adding store instances.
