Undefined index: extension at /var/www/owncloud/apps/files_versions/lib/storage.php#320

[enoch85]

Just wanted to inform you about an undefined index:

Error   PHP Undefined index: extension at /var/www/owncloud/apps/files_versions/lib/storage.php#320 2015-02-20T08:37:19+00:00

ownCloud 8.0

I tried creating versions for a file without extension, but couldn't make this warning appear (on stable8).
It must be something else.

@PVince81 Thanks for trying.

@enoch85 any idea how to reproduce this (maybe you can try to find which file was deleted/created/restored/whatever at that time from your access log?

Access.log from the same timespan:

Just had the same issue on 8.0.1 while deleting files via webdav using the desktop client

[DeepDiver1975]

{"reqId":"54fcf1ebeaae2c6b7799ec7fc8a34b7f","remoteAddr":"192.168.178.24","app":"PHP","message":"Undefined index: extension at /home/deepdiver/Development/ownCloud/stable8/apps/files_versions/lib/storage.php#320","level":3,"time":"2015-03-05T15:14:11+00:00"}

And I'm left with two stray version files ... awesome

[PVince81]

That could smell like concurrency, but not sure...

[iwurzer]

I have the same messages in our oc.log (OC 8.0.3, Windows Client 1.8.1)

Important: yesterday we had again some "mystic" file deletions. That means that a client, deleted some files/folders without an "user command". Short after this the same user - and only he/she" gets the entry within the log: {"reqId":"9c0cdcd6d6c2be2312cb203f5f6f5433" remoteAddr:"xx.xx.xx.xx" app:"PHP" message:"Undefined index: extension at /var/www/owncloud/apps/files_versions/lib/storage.php#320" level:3 time:"2015-06-23T17:17:55+02:00"}

For us (company) this is a "no go" because there is nearly no trust anymore within owncloud, because you cannot be sure, that your data is safe...

If needed - I have access.log, owncloud.log - but no client.log

[PVince81]

@iwurzer the mystic deletion could have been be #13391 when renaming a huge folder.

@enoch85 also there were issues with the versions app where moving a folder didn't always move the versions with them. This should be fixed in 8.0.6 and 8.1.1

Please reopen if you still see these warnings in 8.1.1.
