possible issue in mod_perl 2.0.4 with respect to STDERR

--001636e1f93d82dc2b04782b4c82
Content-Type: text/plain; charset=ISO-8859-1

Configuration error log is in my applications httpd config file is


ErrorLog = "'| rotatelogs \log\error_log 1M "'

But if print something on STDERR from mod_perl program , Say debug print
(print STDERR "DEBUG ";) this is going to \log\error_log instead of
\log\error_log.NNN

Is this is a mod perl issue or i am doing something wrong

I suspect this ErrorLog directive resides inside a VHost?

STDERR is bound to the programs notion of file descriptor 2 or whatever
it is on windows, not to the ErrorLog.

If you want to write to a VHost's ErrorLog use $r->log &co.

In addition to what is said here
http://www.gossamer-threads.com/lists/modperl/modperl/99248# 99248
another way to capture STDERR could be a PERLIO layer or to tie STDERR
to something.

No its not VHOST

Now what i don't under stand is when print STDERR why its printing to
/nfs/private/user/sns/log/ursforms.myserver-44088.log how does it know this
file ?
