#264 fixed xcache fails with hardlinked sources and gallery2 moo Der_Judge

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 , another one at and a third one at on the same server and xcache is active. Now someone accesses and afterwards the other ones. This will result in that way, that everyone who visits _any_ of these galleries will see the content of .

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).

#97 invalid var cache is loosing his value after some time (3-4 hours) moo Dioxin


the var cache is loosing his value after some time (3-4 hours). we store two big string arrays in the cache and after some time, the caching is getting purged automatically.

we set the cache entries via: xcache_set('wikiCache', $wikiCache, 0);

any known issues about this?

what does this setting mean: xcache.var_gc_interval=300

no explanation found in the docs.

thank you in advance :)
