PHP 5.2 Patch: http://public.vbulletin.com/bugs/php/gd-mutex-patch.txt libGD Patch: http://public.vbulletin.com/bugs/php/libgd-mutex-patch.txt Explanation: * pthread now initialises the mutex only once * win32 can set the mutex within DLLMain * Race condition fix by locking prior to checking font cache Problems not fixed: * calling gdFontCacheSetup before obtaining a lock is going to cause the race condition still, I know the ruby wrappers do this. * Unusure about behaviour of using the non bundled GD library on windows with PHP since DLLMain and gdFontCacheMutexSetup may setup the critical section twice. Could make gdMutexSetup(x) a no-op for win32 too. ------------------------------------------------------------------------ [2007-03-23 01:21:26] paj...@php.net Hi Scott, Nuno, "Regarding the patch to the bundled GD library and the php wrapper, does it look reasonable? We've been running it for the past 2 days now without issue on a production server. I'd rather see something put into 5.2.2 " Yes, the patch for php (and unix) looks good. I will apply it during the weekend as well (or Nuno, you can do it if you have the time before). For the windows version, that's a good news, thanks to take the time to work on it. ------------------------------------------------------------------------ [2007-03-23 00:31:35] scottmacvicar at ntlworld dot com I have some time to spare over the weekend and a copy of VC6 installed now so I'll have a go at the win32 implementation. Regarding the patch to the bundled GD library and the php wrapper, does it look reasonable? We've been running it for the past 2 days now without issue on a production server. I'd rather see something put into 5.2.2 and then fix libGD. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
