Subject RE: os-windows/5171: Apache server goes into an infinite loop aft er CGI error

Yes, when I was debugging the loop I checked that errno was indeed EINTR.

I don't think the Win32 C RTL actually uses EINTR. It was likely set by
Apache itself
e.g. here in main\buff.c (sendwithtimeout):
			WSASetLastError(EINTR);	/* Simulate an alarm() */

There are several places where errno is set to WSAGetLastError, so this call
have the indirect effect of setting errno to EINTR.

At least, that is my conjecture. I didn't actually observe EINTR being set
on; it was
already set by the time I broke into the process to debug it.

Scanning through the code, there are quite a few loops that check EINTR.
Maybe the loop
you are still observing is happening somewhere else besides the one stuck
loop that I encountered.

Jim, thanks for the info. Did you verify that errno 
was indeed set to EINTR? I have a fix for this in the 
current development tree, but one tester is still reporting the infinite
loop problem. 

If you are interested, you can download the latest development code for
Apache 1.3 from http://dev.apache.org/from-cvs and give it a spin. 
I'd be interested to know if you still see the same problem.
