[7.0.3RC1] Repeated log message: touch() UTime failed permission denied

[PVince81]

On OC 7.0.3 RC1 my log is full of:

{"reqId":"54456cf12cd77","app":"PHP","message":"touch(): Utime failed: Permission denied at \/srv\/www\/htdocs\/owncloud\/lib\/private\/config.php#141","level":3,"time":"2014-10-20T20:13:37+00:00","method":"PROPFIND","url":"\/remote.php\/webdav\/clientsync"}

They appeared while the sync client was running.

The permissions seem to be correct:

-rw-rw---- 1 root www  541 Oct 20 22:16 config.php

drwxrwx---   2 wwwrun  www 4.0K Oct 20 10:40 config

Note: this is installed from the openSUSE 13.1 RPM, so the permissions should be correct.
If not, we need to find how to tweak them.

Discussed this with @LukasReschke and we can't explain why it is logging messages even though the @touch call is done with a @ which should eliminate such warnings.

Needs further research.

@craigpg @MTRichards @karlitscheck potential log filler

This is the full listing of my config dir:

vincent-server:/srv/www/htdocs/owncloud # ls -l config
total 36K
-rw-r----- 1 root root 458 Nov 19  2013 config.debug.php
-rw-rw---- 1 root www  541 Oct 20 22:22 config.php
-rw-r----- 1 root www  23K Oct 16 08:46 config.sample.php
-rw-r----- 1 root www   55 Aug 20 12:54 noupdate.config.php

From what I saw in the code there's a loop that goes over all the config files, and it probably also looks at that file "config.debug.php" which has different permissions and tries to touch it.
This would explain the "permission denied" issue.
But doesn't explain why the message is still logged.

To make the messages disappear, I needed to set group writing permissions on ALL files in the config folder:

-rw-rw---- 1 root www 458 Nov 19  2013 config.debug.php
-rw-rw---- 1 root www 541 Oct 20 22:24 config.php
-rw-rw---- 1 root www 23K Oct 16 08:46 config.sample.php
-rw-rw---- 1 root www  55 Aug 20 12:54 noupdate.config.php

@LukasReschke should maybe the touch() be only applied to the actual config.php, not the other files ?

Still getting this in 7.0.3RC2 on my server and it is annoying.
I hope it doesn't have any side effects...

I'll take a look tomorrow. Shouldn't have any side-effects except potentially spamming your logs ;)
