Dear Martin,
I changed to eaccelerator, but this locked my MOODLE 1.8 with message:
Fatal error: Call to undefined function _rm() in /home/eadcom/public_html/lib/eaccelerator.class.php on line 65
Now I have a BIG PROBLEM, because my moodle is out.
How Can I go back to NONE ?
Tks a lot.

As an emergency fix, you can put in your config.php file a line saying

 $CFG->rcache = false;

right after the lines that show the database connection details.

Martin,
First I wanted to offer my thanks for your suggestions in this thread. I was at my wit's end trying to figure out how to get back into my moodle after this same problem occurred for me. black eye

I wonder if you might have a suggestion about how the settings for that page should be set. I have enabled the APC module on my server but I have no idea what the settings should be for the performance page. I don't want to screw it up again but uploading of files is painful for my learners.

Applied a patch to 1.8 and 1.9/HEAD to prevent Moodle from breaking if you say you have eaccelerator... and you don't. Or you did, but was disabled.

The code was catering for the situation, but there was a subtle error in the logic.

Unfortunately, APC is not supported in rcache (Moodle still takes advantage of the main aspect of APC and other precompilers... the precompiler itself!).

Does APC have shmem abilities these days? If it does, we could have a plugin - just someone needs to write it wink

Martin - APC uses shmem by default. I've created MDL-11375 as a request to create the plugin. I believe this would be especially helpful considering that PHP6 plans to include APC by default. Peace - Anthony

Hmmm. Looking at http://au2.php.net/apc it looks like it offers shmem services (apc_add(), apc_store(), etc). So yep, an APC user could roll up their sleeves and add APC support.

If the semantics of the shmem API are the same as for eaccelerator, then you can probably just make a copy of the eaccelerator class and hack it till it works.

And I have an initial implementation of this. All I need is testers wink

You need these 3 patches. It is part of a larger patchseries that give Moodle a big perf boost. A few of them are in 1.9 already, others are delayed for 2.0.

Implement the class...
