Subject:   One of two gdawful bugs in Apache/Win32, start capturing child errors.
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a6af5d1be04edfc1456fa586797447ec2f2e58b3;p=thirdparty%2Fapache%2Fhttpd.git

  One of two gdawful bugs in Apache/Win32, start capturing child errors.
  The other [significant] error is the tendancy for the parent to restart
  instantly on init errors, which are never corrected.  But that's a patch
  for another day.

 Changes with Apache 1.3.23
 
+  *) Cause Win32 to capture all child-worker process errors in
+     Apache to the main server error log, until the child can
+     open it's own error logs.  [William Rowe]
+
   *) Revert mod_negotation's handling of path_info and query_args
      to the 1.3.20 behavior.  PR: 8628, 8582, 8538  [William Rowe]
