This code was originally taken from; https://github.com/durana/moodle-cachestore_redis
Special thanks to Mark Nielsen and Adam Durana for their work on this.
Since the original import;
- Mode session support has been added.
- Some cleanup of names has been made.
- Data guarantee and references support was added.
The SDK that this plugin was designed around is not compatible with recent
versions of Alfresco so the decisio has been made to move the repository to
the plugins database.
Introducing both APIs in moodle along with:
- search_box widget to add a tiny search box
- admin settings with setup steps helper
- cache for search results
- template for a search result
- php unit stuff
Many thanks to Tomasz Muras, Prateek Sachan and Daniel Neis for their contributions, for starting this development
and for pushing for it to be completed. Also thanks to other contributors: Jonathan Harker and eugeneventer.
The admin setting updateautodeploy no longer exists. The two existing
config.php flags $CFG->disableupdateautodeploy and
$CFG->disableonclickaddoninstall merged into a single 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).
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.
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 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.
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.
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.
