svn commit: r428029 - in /httpd/httpd/trunk: CHANGES os/win32/util_win32.c server/mpm/winnt/child.c

New Revision: 428029

URL: http://svn.apache.org/viewvc?rev=428029&view=rev
Log:
Fix return values from wait_for_many_objects.
The return value is index to the signaled thread in
the creted_threads array.
We can not use WAIT_TIMEOUT as return value
because its value is defined as 258, thus limiting
the MaxThreads to that value that leads to the
assertion errors.

 Changes with Apache 2.3.0
   [Remove entries to the current 2.0 and 2.2 section below, when backported]
 
+  *) mpm_winnt: Fix return values from wait_for_many_objects.
+     The return value is index to the signaled thread in the
+     creted_threads array. We can not use WAIT_TIMEOUT because
+     his value is defined as 258, thus limiting the MaxThreads
+     to that value. [Mladen Turk]
+
   *) mod_proxy_balancer: Workers can now be defined as part of
      a balancer cluster "set" in which members of a lower-numbered set
      are preferred over higher numbered ones. [Jim Jagielski]
