From 377fdf3860e317b68392c678fa25e081251baecc Mon Sep 17 00:00:00 2001 From: Vincent Petry Date: Thu, 19 Jan 2017 15:02:46 +0100 Subject: Skip null groups in group manager (#26871) (#26956) * Skip null groups in group manager (#26871) * Skip null groups in group manager * Also skip null groups in group manager's search function * Add more group null checks in sharing code * Add unit tests for null group safety in group manager * Add unit tests for sharing code null group checks * Added tests for null groups handling in sharing code * Ignore moveShare optional repair in mount provider In some cases, data is inconsistent in the oc_share table due to legacy data. The mount provider might attempt to make it consistent but if the target group does not exist any more it cannot work. In such case we simply ignore the exception as it is not critical. Keeping the exception would break user accounts as they would be unable to use their filesystem. * Adjust null group handing + tests * Fix new group manager tests Signed-off-by: Morris Jobke --- lib/private/Share20/DefaultShareProvider.php | 4 ++++ lib/private/Share20/Manager.php | 13 +++++++++---- 2 files changed, 13 insertions(+), 4 deletions(-) (limited to 'lib/private/Share20') diff --git a/lib/private/Share20/DefaultShareProvider.php b/lib/private/Share20/DefaultShareProvider.php index fe6472c31a0..e4ae26be13d 100644 --- a/lib/private/Share20/DefaultShareProvider.php +++ b/lib/private/Share20/DefaultShareProvider.php @@ -329,6 +329,10 @@ class DefaultShareProvider implements IShareProvider { $group = $this->groupManager->get($share->getSharedWith()); $user = $this->userManager->get($recipient); + if (is_null($group)) { + throw new ProviderException('Group "' . $share->getSharedWith() .
