[Owncloud] ownCloud 5 encryption pre release

[Dirk Kastens]

Hi,

I just installed the pre release and tried the new encryption feature. I 
upgraded from 5.0.6 using rsync.

OS: Scientific Linux release 6.4 (Carbon)
HTTP: Apache 2.2.15-28.sl6
PHP: 5.3.3-22.el6

There are some problems:

1. There are lots of errors in the owncloud.log:

{"app":"PHP","message":"Call to a member function getFileInfo() on a 
non-object at 
\/var\/www\/html\/owncloud\/lib\/files\/filesystem.php#621","level":4,"time":1369737911}

2. I'm authenticating against LDAP. After enabling encryption, the first 
login always fails with HTTP error 500. After reloading the page, I'm 
logged in.

2. owncloud becomes EXTREMELY slow after enabling encryption. Changing a 
directory in the web interface takes about 30 seconds. I first had to 
increase the memory limit in php.ini to 2048M to get owncloud to work. 
Before that I always got the error:

{"app":"PHP","message":"Allowed memory size of 1073741824 bytes 
exhausted (tried to allocate 1484274654 bytes) at 
\/var\/www\/html\/owncloud\/lib\/files\/storage\/local.php#113","level":4,"time":1369732536}

3. Opening a big text file (an export of my Windows firewall rules), the 
text editor shows garbage on some lines (see attached pictures. The 
first shows the file with encryption disabled, the second with 
encryption enabled). The garbage occurs in regular intervals several 
times in the big file. The file itself seems to be ok, because the 
downloaded file looks good.
