Re: Scripts works under CGI but not under mod_perl

["Manoj Bist" <suppressed>]

Hi Perrin,

Is there some recommended way to detect if STDOUT is being manipulated?  
This is what I am doing.

1. Build a standalone binary that uses this lib.
2. Run this binary in the debugger and insert breakpoints in read, write, open and close.

The library is using TCP sockets to communicate with the server.

Is  there some way to debug apache/mod_perl in the debugger?  

Thanks a lot,

Manoj.

Okay, so that's what you need to focus on.  Do you know if it's
connecting over TCP sockets or pipes?  There may be issues if it's
trying to manipulate STDOUT.

I don't see how this could cause you trouble, unless you are loading
other things directly from httpd.conf.  It probably has to do with
STDOUT.
