In some situations, a group share is created before a user share, and
the recipient renamed the received share before the latter is created.
In this situation, the "file_target" was already modified and the second
created share must align to the already renamed share.
To achieve this, the MountProvider now groups only by "item_source"
value and sorts by share time. This makes it so that the least recent
share is selected as super-share and its "file_target" value is then
adjusted in all grouped shares.
This fixes the issue where this situation would have different
"file_target" values resulting in two shared folders appearing instead
of one.
* Wait for socket to be open
* Fix call on null
* Allow DB access for MountProviderTest
Makes unit tests pass when using object store, since their FS access is
actually oc_filecache DB access. It is currently not possible to mock
or bypass the logic from "SharedMount::verifyMountPoint()" triggered by
this test.
Link shares always allowed deletion, however internally the permissions
were stored as 7 which lacked delete permissions. This created an
inconsistency in the Webdav permissions.
This fix makes sure we include delete permissions in the share
permissions, which now become 15.
In case a client is still passing 7 for legacy reasons, it gets
converted automatically to 15.
* Move used OC_Group_xx to \OC\Group
* Add (deprecated) legacy wrapper in legacy, OC_Group_xx
* Replace deprecated use of OC_Group_xx with \OC\Group\xx
E-tag propagation replies on the mtime of the file. Order of events:
1. add file 'foo.txt' with content 'bar'
2. Set mtime to now() - 1
3. Check if etag changed.
Now this goes right often when 1 and 2 happen in the same second.
However imagine
1. add file 'foo.txt' with content 'bar' (at t=0.999)
2. Set mtime to now() - 1 (at t=1.001)
Now the mtime will be set to the same time. Thus not chaning the etag.
