Right, for an even further concern, what if libxml was used in a portion of the entire process outside the PHP code..? (e.g. in a Apache module). If such collision could well happen, we'd be better off leaving it use the ordinary allocators. On the other hand, it should be worth paying attention to that circular references are big threats against reference count based garbage collection. As we have to handle memory allocations with great care in threaded servers, it'd be safer to use Zend's MM here. > Then, do we even need to worry about re-entrance then? > So, we may define the same memory handling functions a few times. > xmlInitParser is already re-entrant safe. IMO the point is xmlInitParse() itself is designed to be reentrant while it isn't when it comes to the memory manager.. But I'm not sure if libxml is actually reentrant then :) Moriyoshi -- PHP CVS Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
