Description Nikita 2010-05-06 08:50:03 UTC

libXML from /usr/ports/textproc/libxml2 + php from /usr/ports/lang/php5 + memcached from /usr/ports/databases/pecl-memcaced = crash :)

I propose patch to fix it (in attachment), but I dont know is this best way, or my patch may break other software?

Fix: Use a patch in attachment.

Patch attached with submission follows:
How-To-Repeat: 1) Install PHP 5.3.0 from ports.
2) Install pecl-memcached from ports (or directly from PECL, using pecl install memcached) with sessions support.
3) Run any operation, like php -m or php -v.

I've the same problem here, on 7.3 Release, no memcached.
I had to remove the last part of /usr/ports/textproc/libxml2/files/ 
patch-configure in order to get a stable PHP.

Change from gnome to ale. Can you help us with this threads issue? I don't 
understand and know what's going on with your change of threads stuff in 
the libxml2 and other PHP modules.

From-To: open->feedback

Disabling thread-safety in libxml2 is not the right fix. 
The issue is that libmemcached is a multi-threaded library, 
while PHP is not linked with libthr and call dlopen/dlclose on it. 
Try compiling PHP with the new LINKTHR option.
