Description:
------------
I use php as an ISAPI server extension on my self-written web server.
Works quite well, except when I remove the extension from memory, i.e.,
FreeLibrary(hInst) where hInst is the handle to php4isapi.dll. In most
cases, this causes the DLL to go belly-up.
I traced the problem into the Zend stuff - in zend_shutdown() there's a
call to zend_shutdown_timeout_thread() which terminates the timeut
thread... or at least it's supposed to do so. Unfortunately,
zend_shutdown_timeout_thread() just posts a WM_QUIT message for the
thread and then happily goes on deleting thread data... and when the
timeout thread finally processes the WM_QUIT message, all data are
gone, and it hops to an unused address.
Solution to this problem is simple - just make sure that
zend_shutdown_timeout_thread() allows the other thread to receive the
WM_QUIT message before continuing. I've included a modified version in
the "reproduce code" area below which has the desired effect.
Reproduce code:
---------------
void zend_shutdown_timeout_thread()
{
if (!timeout_thread_initialized) {
return;
}
PostThreadMessage(timeout_thread_id, WM_QUIT, 0, 0);
Sleep(0); // <- this does the trick!
}
