From c20e9ae8362fbb10bccd02e91100d25b720db95b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?David=20Mudr=C3=A1k?= Date: Fri, 9 Oct 2015 18:07:28 +0200 Subject: [PATCH] MDL-49329 admin: Add ability to cancel upgrade of the plugin 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). --- admin/index.php | 141 ++++++++++++++++----- admin/renderer.php | 74 +++++------ lang/en/admin.php | 2 +- lang/en/plugin.php | 5 +- lib/classes/plugin_manager.php | 67 +++++++++- theme/bootstrapbase/less/moodle/admin.less | 2 +- theme/bootstrapbase/style/moodle.css | 2 +- 7 files changed, 217 insertions(+), 76 deletions(-) diff --git a/admin/index.php b/admin/index.php index f9bf80d90d183..b2ccf8c99ecdf 100644 --- a/admin/index.php +++ b/admin/index.php @@ -112,6 +112,9 @@ $abortinstall = optional_param('abortinstall', null, PARAM_COMPONENT);
