* Plugins can now explicitly declare supported and incompatible Moodle
versions in version.php
- $plugin->supported[37,39];
supported takes an array of ascending numbers, that correspond to a
range of branch numbers of supported versions, inclusive. Moodle
versions that are outside of this range will produce a message
notifying at install time, but will allow for installation.
- $plugin->incompatible = 36;
incompatible takes a single int corresponding to the first incompatible
branch. Any Moodle versions including and below this will be prevented
from installing the plugin, and a message will be given when
attempting installation.
The previous version of the plugin manager's method
get_remote_plugin_info() was suitable for installing missing
dependencies only. To make use of for installing new plugins and/or
available updates, it must be clear that we are requesting information
for the particular plugin version only, not "given or higher" version.
The patch improves the dependencies resolution in the plugin manager so
that the information about availability of the missing dependency is
included and can be displayed at the Plugins check screen during the
upgrade.
The actual loading of available updates info objects is moved back to
the plugin manager class. As we can now mockup the manager in unit
tests, this allows us to bypass the real \core\update\checker and have
unit tests for \core\plugininfo\base::available_updates().
We can now override the plugin manager's methods in the testable
subclass while still keeping the singleton behaviour of it. The change
makes use of late static binding.
