From c948b813aef5f061e571be7080801ec92e1aa79b Mon Sep 17 00:00:00 2001 From: =?utf8?q?David=20Mudr=C3=A1k?= Date: Wed, 7 Oct 2015 14:40:43 +0200 Subject: [PATCH] MDL-49329 admin: Add plugin manager method for installing remote packs 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. --- admin/renderer.php | 45 +++++- lang/en/admin.php | 4 +- lang/en/plugin.php | 6 + lib/classes/plugin_manager.php | 176 +++++++++++++++++++++ theme/bootstrapbase/less/moodle/admin.less | 13 ++ theme/bootstrapbase/style/moodle.css | 2 +- 6 files changed, 237 insertions(+), 9 deletions(-) diff --git a/admin/renderer.php b/admin/renderer.php index 5a760aa8a56..b6cc6adf9ff 100644 --- a/admin/renderer.php +++ b/admin/renderer.php @@ -999,6 +999,16 @@ class core_admin_renderer extends plugin_renderer_base { ); } + $installableupdates = $pluginman->filter_installable($pluginman->available_updates()); + if ($installableupdates) { + $out .= $this->output->single_button( + new moodle_url($this->page->url, array('installupdatex' => 1)), + get_string('updateavailableinstallall', 'core_admin', count($installableupdates)), + 'post', + array('class' => 'singlebutton updateavailableinstallall') + ); + } + $out .= html_writer::div(html_writer::link(new moodle_url($this->page->url, array('showallplugins' => 0)), get_string('plugincheckattention', 'core_plugin')).'
