Orientation for shared images broken #20484

After upgrading ownCloud to version 8.1.4, shared images (including thumbnails) that require rotation are no longer being rotated in the UI. This is only happening when an account other than the owner of the image is accessing it. The owner can still see all the thumbnails and images with a correct orientation based on EXIF data.

Example of debug entries in the log when one of these shared images is accessed:

{"reqId":"8+4ddYHXwnHf3I\/TBn+e","remoteAddr":"","app":"core","message":"Generating preview for \"\/shared folders\/photos\/Camera New (test)\/20151108_115921.jpg\" with \"OC\\Preview\\JPEG\"","level":0,"time":"November 12, 2015 07:06:22","method":"GET","url":"\/owncloud\/index.php\/core\/preview.png?file=%2Fshared+folders%2Fphotos%2FCamera+New+%28test%29%2F20151108_115921.jpg&c=3d7aac3fcadb160785927bd393424122&x=36&y=36&forceIcon=0"}

The problem seems to be caused by a change in 'lib\private\preview\image.php'. Here's the diff between the code in 8.1.3 and 8.1.4:

<       if ($fileInfo['encrypted'] === true) {

>       $useTempFile = $fileInfo->isEncrypted() || !$fileInfo->getStorage()->isLocal();
>       if ($useTempFile) {
>       if ($useTempFile) {
>           unlink($fileName);
>       }

I have no external storage and no encryption configured on my server, but for some reason, the shared file path becomes something like '/tmp/oc_tmp_1SPFjp-.JPG', which causes the EXIF info lookup to fail. I didn't know what the right fix would be here since I'm not familiar with the "larger picture" but reverting to the code snippet above fixed my problem. Just raising this in case anyone else notices this issue. All this was happening on an otherwise unchanged CentOS 6 / Apache 2.2 / PHP 5.6 server with ownCloud running on it for over a year and a half without issues.

It would be good to know if this is also a problem on 8.2


The problem is due to the shared storage not implementing isLocal thus defaulting to false

Implementing isLocal for the shared storage isn't possible atm without major hacks due to the way the shared storages is implemented

OK, so it's still happening on 8.2 and what would be the long term solution then and for which milestone?

@icewind1991 what do you think ?


sorry, there is a workaround for it to look good in the shared users?

Still having this problem on 8.2.2 when uploading pictures with an admin account into a folder shared by another user:

When uploading the exact same file as the user that owns this share there isn't a problem at all and rotating works as expected:

Same problem here - would be very happy if this could be solved. Thank you!


Fix is here: #21615


Thank you!

@MorrisJobke Could this be backported to 8.2 ?
