At pfSense we are currently trying to integrate Xcache together with PHP 5.2.0. Unfortunatly XCache behaves quite unstable and causes lots of core dumps.

Disabling XCache, solves these issues.

I was able to track it down to the fact, that the following page allways results in a HTTP 500 if beeing saved and if using Xcache:

​http://pfsense.com/cgi-bin/cvsweb.cgi/pfSense/usr/local/www/system_advanced.php?rev=1.191;content-type=text%2Fx-cvsweb-markup

If trying to save the above page using EAccelerator I do not get a HTTP 500.

I even tried to use XCache v1.1.0 but the issue remains.

Enabled/Used? modules (in that order):

# add additional extensions below
extension=xcache.so
#extension=xdebug.so
extension=radius.so
#extension=suhosin.so
#extension=uuid.so

# standard PHP extension
extension=bz2.so
extension=bcmath.so
extension=ctype.so
extension=curl.so
extension=gettext.so
extension=mbstring.so
extension=pcntl.so
extension=posix.so
extension=session.so
extension=shmop.so
extension=sysvmsg.so
extension=sysvsem.so
extension=sysvshm.so
extension=tokenizer.so
extension=xml.so
extension=simplexml.so
extension=zlib.so

XCache config:

[xcache]
xcache.mmap_path = "/tmp/xcache"
xcache.cacher = On
xcache.size = 6M
xcache.stat = On
xcache.optimizer = On
auto_globals_jit = Off

xcache loads cached PHP files when directory name is changed

xcache will load a pre-compiled PHP file if the directory name is changed. For example:

+ Create folder1 + Create file1.php ++ Inside file1 type:

<?php echo dirname(FILE); ?>

+ Save file1.php + Browse to ​http://dom.ext/folder1/file1.php + Copy contents to text editor

+ Rename folder1 to folder2. Keep file1.php name intact. + Browse to ​http://dom.ext/folder2/file1.php + Copy contents to text editor

+ You will notice the contents are the same and xcache is using the older version of the PHP script even though clearly the directory path has changed.

-- Note: Might not be an xcache bug, but it's annoying and replicable on other systems all the same. Happens with APC (Alternative PHP Cache) too.

Thank you, Best Regards,

Hi there,

I'm running several servers with Gentoo Linux. Gentoo Linux uses a concept of hardlinking sources of php apps to achieve multiple goals:

• It saves a lot of diskspace / inodes
• You can update all instances of this software at the same time
• The caching of sources with eaccelerator or xcache is more effective, since all identical scripts have to be cache only once
• Backups are done faster

...

In short: There are many pluses by using this concept, which is why many other people are using this concept besides from Gentoo, too.

On the xcache website is a list of tested applications, including Gallery2. I'm using Gallery2 with xcache and hardlinked sources on my server and I'm encountering the same issue with xcache now which I encountered using eaccelerator:

When xcache is active, on _every_ site that content of the gallery is shown, which first hit the cache. For example: You are running a gallery2 at ​http://www.example.org/gallery2 , another one at ​http://www.example.org/gallery2-new and a third one at ​http://www.example2.org/gallery2 on the same server and xcache is active. Now someone accesses ​http://www.example.org/gallery2 and afterwards the other ones. This will result in that way, that everyone who visits _any_ of these galleries will see the content of ​http://www.example.org/gallery2 .

I can provide a root login and a demo if necessary, but I'd like to not post it here. I'm loged in to freenode everyday and my registered username is "Judge" there. A second option to get in contact is to instant message me with AIM - my Screenname is mfcjudge . I Also use Jabber : thejudge@… . Finally, you can write me a email at mailYYYY@… (replace YYYY by current year).
