Subject: Re: [PHP-DEV] Multithreaded C Gearman worker to run PHP scripts
From: thomas@koch.ro (Thomas Koch)

As Johannes suggested (thx!) I made a gearman_worker sapi:

http://github.com/thkoch2001/php-
src/tree/857657ddce9aad9709cc39832fb716555021725c/sapi/gearman_worker

(or http://tinyurl.com/gearmanworkersapi )

and linked the old code against it:

http://github.com/thkoch2001/gearman-php-worker/

It starts now, waits for tasks, but segfaults as soon as a task is received. 
Need to debug it tomorrow.

If anybody wants to guide me... :-) It seems that something with opening the 
script files goes wrong:
