From c3fe22633b56e7b5cef38500ac4c6e9d69fdc801 Mon Sep 17 00:00:00 2001 From: Vincent Petry Date: Wed, 28 Jun 2017 18:55:39 +0200 Subject: [PATCH 01/13] Add repair step to repair mismatch filecache paths Whenever a parent-child relationship describes a specific path but the entry's actual path is different, this new repair step will adjust it. In the event where another entry already exists under that name, the latter is deleted and replaced by the above entry. This should help preserve the metadata associated with the original entry. --- lib/private/Repair.php | 2 + .../Repair/RepairMismatchFileCachePath.php | 407 ++++++++++++++ .../RepairMismatchFileCachePathTest.php | 495 ++++++++++++++++++ tests/lib/TestCase.php | 6 +- 4 files changed, 909 insertions(+), 1 deletion(-) create mode 100644 lib/private/Repair/RepairMismatchFileCachePath.php create mode 100644 tests/lib/Repair/RepairMismatchFileCachePathTest.php diff --git a/lib/private/Repair.php b/lib/private/Repair.php index fe9e6ba756a6..968db2ce8d04 100644 --- a/lib/private/Repair.php +++ b/lib/private/Repair.php @@ -53,6 +53,7 @@ use Symfony\Component\EventDispatcher\EventDispatcher; use Symfony\Component\EventDispatcher\GenericEvent; use OC\Repair\MoveAvatarOutsideHome; +use OC\Repair\RepairMismatchFileCachePath; class Repair implements IOutput{ /* @var IRepairStep[] */ @@ -126,6 +127,7 @@ public function addStep($repairStep) { public static function getRepairSteps() { return [ new RepairMimeTypes(\OC::$server->getConfig()), + new RepairMismatchFileCachePath(\OC::$server->getDatabaseConnection(), \OC::$server->getMimeTypeLoader()), new FillETags(\OC::$server->getDatabaseConnection()), new CleanTags(\OC::$server->getDatabaseConnection(), \OC::$server->getUserManager()), new DropOldTables(\OC::$server->getDatabaseConnection()), diff --git a/lib/private/Repair/RepairMismatchFileCachePath.php b/lib/private/Repair/RepairMismatchFileCachePath.php new file mode 100644 index 000000000000..14a9f920a3cd --- /dev/null +++ b/lib/private/Repair/RepairMismatchFileCachePath.php @@ -0,0 +1,407 @@ + + * + * @copyright Copyright (c) 2017, ownCloud GmbH + * @license AGPL-3.0 + * + * This code is free software: you can redistribute it and/or modify + * it under the terms of the GNU Affero General Public License, version 3, + * as published by the Free Software Foundation. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
