This is not really necessary as there is no actual change in the
behaviour of the updates API between 1.2 and 1.3. However, as we plan to
use the new \core\update\api client for this in the future, it makes
only sense to have these two synced already now. In other words, Moodle
3.0 site will use the same version 1.3 for all download.moodle.org/api
end points.
This was a regression of my recent improvement of rendering the "Check
for updates" button. There is now unified parameter ?fetchupdates=1 that
can be used on either admin/index.php or admin/plugins.php, so that we
can use a common UI widget for both locations (without the need to pass
the URL explicitly).
The admin setting updateautodeploy no longer exists. The two existing
config.php flags $CFG->disableupdateautodeploy and
$CFG->disableonclickaddoninstall merged into a single one.
General backup/restore does not need to handle external data sources natively - so
any changes needed to achieve this should be contained to the plugin that needs it.
Using standard subplugin support, this commits implements
the restore of logstore subplugins in general and the
standard logstore is particular. Notes:
- TODO: Decide about these 2 pending issues:
1) Some logs are already created (events fired) by the restore process itself. Every time
an API is used and it fires events... corresponding (and actual!)
logs are created. We need to prevent restore to duplicate them (or,
alternatively, stop firing events when restore is happening).
2) There are 2 pieces of information in the logs that, right now, can
not be restored, because the process does not know enough to be able
to remap that information to its new counterparts. We are talking
about objectid and other columns. So we need to specify, in some way
understandable by restore, to which existing mappings they correspond
to.
Using standard subplugin support, this commit implements
the backup of logstore subplugins in general and the
standard logstore in particular. Notes:
- Uses a custom final element (base64_encode_final_element) to
support the storage of serialized 'other' information in logs.
- Organization: Instead of directly extending backup_subplugin,
every logstore extends backup_tool_log_logstore_subplugin just
in case any shared code is needed in the future.
- Implements both course and activity logs, sharing the structure
completely (both are based in contextid to pick the target
information, from database or whatever other logstores use).
In order to implement the backup and restore of log stores, that
are created as subplugins of the tool_log plugin , we need to
extend subplugins support from activities to virtually any plugin.
Basically that implies moving the add_subplugin_structure() method from
its current, restricted, activity level to general restore_structure_step.
This commit implements the change in restore, covered with tests verifying
old, bc behavior and also new, general one.

If there is an available archived zip with the version of the plugin
currently installed, we can use it to cancel/abort the upgrade of the
plugin. This is internally handled as the installation of the archived
zip and goes through all the validation and confirmation.
Additionally, some other parts were improved. Most notably, renderer no
longer decides itself if some installation can be cancelled but it
always asks the controller (plugin manager).
The button for installation was moved to the left so there should be
first buttons to add things, and then buttons to cancel things (which is
common in normal forms).
The method move_plugin_directory() was a relict from previous 2.9
implementation within tool_installadon_installer and was originally
supposed to be used to move whole plugin folders. The archiving feature
has been finally implemented via using zip files (so that we do not have
actual PHP code present in the dataroot) and we do not need this method.
This should allow the admin to revert the upgrade of existing plugins,
such when the dependency chain leads to a dead-end. Additionally, we
archive (as a last-chance copy) the to-be-installed plugins when
cancelling their installation. This is mainly for developers who could
otherwise loose their code. For the same reason, plugins are being
archived upon uninstallation, too.
Do not attempt to read an unreadable directory because previously the generated
errors were hard to fathom.
Thanks to James McQuillan for the basis of the patch.
$plugin was not being set before the version file was included.
This caused an E_WARNING: Creating default object from empty value
This change creates the plugin object before the version file sets its parameters.
Most of the functionality provided by this tool (typically the
validation and actual deployment of the plugin package) has been moved
to the core level. So this is becoming just a thin wrapper and user
interface for installing new plugins via the administration UI.
Also fixes MDL-49600 as we no longer keep the unzipped contents of the
packages in the persistent temp directories.
The plugin manager's method install_remote_plugins() has been changed to
install_plugins() and it is now able to install plugins from the
provided list of locally available ZIP files, too. This is used by the
Install plugins admin tool.
During the testing, I was experiencing weird behaviour - after a single
plugin updated was installed, I ended up on admin/index.php?cache=1. I
believe it was caused by the missing opcache_reset().
The plugins check screen (displayed during core upgrade and/or plugins
upgrade) now supports installation of remote plugins. This includes
installation of missing dependencies (both single and bulk mode) and
installation of available updates (both single and bulk mode).
All the HTTP query parameters supported by admin/index.php are now
explicitly enlisted. Previously, the \core\update\deployer used
its own additional parameters (and was source of some serious problems
in the past).
The implementation uses the plugin manager as the controller and
provides an unified interface for installing any remote plugin or
plugins (be it available update or missing dependency).
As a side effect, we now validate available updates which was not
happening before.
The new method core_plugin_manager::install_remote_plugins() will serve
as a backend for all the ways of installing ZIP packages from the moodle
plugins directory, such as installing new plugins (by clicking the
Install button in the plugins directory), installing available updates
(single and bulk mode) and installing missing dependencies (single and
bulk mode).
The method should be used both for validation pre-check screen and,
after the confirmation, for actual installation. Note that we
intentionally repeat the whole procedure after confirmation. Unzipping
plugins is cheap and fast and the ZIPs themselves are already available
in the \core\update\code_manager's cache.
We will need to add support for archiving existing code to prevent
accidental data-loss.
This basically provides what mdeploy.php was doing, but better. We now
have consistent way of installing all remote ZIP packages, always
validate them and we can perform bulk operations, too.
If the grade and submission were modified at exactly the same time,
assume that this means the grade was automatically created for the submission
and is not a real grade from a teacher interaction.
Set the cursor to a pointer for an active tab with a link to
indicate that the tab is still clickable, even though it is
active. See also MDL-46470 and MDL-51207.
Previously, the validator was used for installation of the new plugins
only. We now validate every incoming plugin package. As a result, we
must no longer insists on the target location is empty. Instead, warning
is raised.
Provides a bit more compact layout. Finally cleans up the relevant LESS
files and makes available updates info boxes consistent across all
screens where they are displayed.
The mdeploy.php standalone script (used to download and unzip plugins
into the dirroot) and the \core\update\deployer class (as a
communication bridge between the core and the mdeploy.php) was
originally designed and implemented with the assumption that it would be
eventually used for updating the Moodle core itself, too. Therefore it
was written as standalone utility without dependency on the Moodle core
libraries.
However, it never happened and there is no real demand for that. So now
there is no need to have and maintain a completely parallel solution for
common things like fetching and unzipping plugin ZIPs.
Additional reasoning for mdeploy.php was that the core is not very
reliable during the core upgrade and we could run into various troubles.
This does not seem to be that bad. We rely on a lot of core
functionality (such as output rendering, DB access etc) and plugins
deployment seems to work well (and better) with common core libraries.
So long mdeploy, and thanks for all the hard work you did for us.
If the plugin was missing from disk, the required core version was
displayed as "Moodle {$a}" because the core dependency resolver always
returns an object.
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.
