Well, my main one is in my own extension where I was relying on HANDLE_BLOCK_INTERRUPTIONS and it surprised me that this was a null macro under Apache2. There are a number of sections in the engine using that macro as well. If they aren't needed, we should remove them, but if they are needed, surely they are also needed under Apache2 or other sapis so it would be good to have a sapi-independent mechanism for deferring signals. The Apache2 flakyness I have seen has been weird dangling stuff on shutdown that I always just ignored. -Rasmus -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
