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.
The plugins check screen now provides buttons to cancel installation of
a plugin. Available only for new installations (not upgrades) and for
additional plugins (not standard), given that the web server process has
write access to the plugin folder.
This has also been reported as MDL-48535.
As a part of the patch, there is improved processing of page URLs during
the upgrade. All this dancing around $reload URL is not needed once the
$PAGE->url is properly set to guide the admin on the correct page during
the upgrade process.
This is not really new class. Originally, the validator was implemented
in the scope of the tool_installaddon plugin. But we need its features
in other parts at the core level (e.g. during the upgrade to validate
available missing dependencies or available updates). Looking back, it
was a mistake to have it implemented at the plugin level rather than the
core level.
So this patch moves the tool_installaddon_validator class to
\core\update\validator class, together with associated unit tests,
fixture files and strings. There were changes made in the
tool_installaddon to make use of this new class instead of the old one.
This is a great step towards the bright future, hopefully there won't be
many regressions.

AMOS END
The plan is to have a single tool looking after all operations with
plugin ZIP packages (downloading, unzipping, moving to the dirroot and
back). For legacy reasons, we have that logic currently duplicated in
mdeploy and tool_installaddon. I would like to unify and simplify the
whole machinery to use the same code for available updates, manual
installation and plugin dependencies.
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 purpose of this class is to provide a general client for all APIs
available at https://download.moodle.org/api/ (e.g. available updates,
plugin info, plugins list etc). Currently, fetching data from this API
is done separately at several places. This leads to code duplication and
harder maintenance (I know it well).
Additionally, the existing client was implemented as
tool_installaddon_pluginfo_client in the admin/tool/installaddon/ scope.
I will soon need to use the same functionality in the
core_plugin_manager and it would hurt my karma if the core was depending
on a class provided by a admin tool plugin (even if it is standard one).
So, there is new \core\update\api client implementing the version 1.3 of
the pluginfo API. There is a TODO note left for remaining services.
The patch moves the resolving logic from the renderer (where it should
not really be) to the plugin manager (controller). This is needed
because we will need the very same logic to be used at other places.
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().
Plugin info objects are owned by the plugin manager (composition
pattern). Even if the plugin manager is a singleton, we need to keep
explicit reference to the plugin manager that owns the plugin info so
that we can mock up things in unit tests.
Therefore this patch introduces a new property of plugin info objects
that holds the reference to the instance of the plugin manager that made
(and hence owns) the given info instance.
The only trouble here is with static methods of plugin info classes such
as \core\plugininfo\base::get_enabled_plugins(). In these cases, the
code keeps using the core_plugin_manager singleton. The solution would
be to pass the plugin manager instance as a parameter but that is not
worth of change for now, IMHO.
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.
Before this patch, whenever core_plugin_manager::get_plugins() was
called, it always attached info about available updates. But this is
needed only in quite rare cases, such as when the admin is looking at
the Plugins overview and Plugins check screens. There is no need to load
this on other places and for non-admin users.
The patch removes the loading from the method
core_plugin_manager::get_plugins_of_type() and implements lazy loading
directly in the plugininfo classes so that it is loaded only when
\core\plugininfo\base::available_updates() is actually called.
The method should check against $CFG->disableupdatenotifications and not
$CFG->disableupdateautodeploy. This had to be a copy&paste mistake from
the \core\update\deployer::enabled().
While looking at it, I also fixed couple of places where this method
should and could be used.
The intention here is to make the table a little bit more compact (using
less columns) and to make use of the bootstrap based label elements if
available.
