For some reason the aws-sdk-php package does not caclulate the
signiture correctly when accessing an object in a bucket with a name of
'.'.
When we are at the top of a S3 bucket there is a need(?) to have a directory
name. Per standard Unix the name picked was '.' (dot or period). This
choice exercises the aws-sdk bug.
This fix is to add a field to the method to store the name to use instead of
'.' which at this point is hard coded to '<root>'. We also add a private
function 'cleanKey()' which will test for the '.' name and replace it with
the variable. Finally all calls to manipulate objects where the path is
not obviously not '.' are processed through cleanKey().
An example where we don't process through clean key would be
'Key' => $path.'/',
Use correct relationship operator
Per feed back use === instead of ==
use '/' instead of '<root>'
Now the external storage correctly returns the mount points visible only
for the current user by using the method getAbsoluteMountPoints() which
is already filtered.
Since that call was missing the backend name which is important for the
UI, this one was added as well.
Each storage backend has a default priority, assigned to any system mounts
created in ownCloud. mount.json can be manually modified to change these
priorities.
The priority order is as follows:
* Personal
* User
* Group
* Global
Within each mount type, the mount with the highest priority is active.
The storage backend defaults were chosen to be the following:
* Local - 150
* Remote storage - 100
* SMB / CIFS with OC login - 90
An issue existed where `readData` used `OCP\User::getUser()` to get the user
for personal mount points, which worked in all situations apart from when a
personal mount point was used for sharing, so the return from `getUser()` is
not the user that owns the share. As such, any personal mount points would not
work correctly when shared.
`readData` and `writeData` have been changed from using a `$isPersonal`
boolean to using a `$user` string|null. `$isPersonal = false` can now be
written as `$user = NULL` (or left out in the case of `readData`), and
`$isPersonal = true` can be written as `$user = OCP\User::getUser()`.
