[mp2] useless warning on ModPerl::Util::exit()
Bug report follows.
Thanks a million.

-------------8<---------- Start Bug Report ------------8<----------
1. Problem Description:
Useless warning in error_log:
[Mon Sep 29 16:43:15 2003] -e: Use of uninitialized value.
This occurs whenever a handler script calls ModPerl::Util::exit()
or simply exit(). There is no other available information.
Running Perl 5.8.0 and mod_perl 1.99.10, both fresh rebuilds from
source today.
This is the *only* warning in a fairly large mod_perl application,
and the only unfixable problem I've had porting it.
Otherwise, thumbs up. mod_perl 2.0 rocks. :)

[mp2] POST form limits; mod_perl + Mozilla Firebird
Posted by ydnar <yd...@paradigm-healthcare.com>.
I have a large form (1000+ form elements) which uses method="POST". Only
the first 429 elements/parameters are passed to my mod_perl application.
The odd thing is, it only happens with Mozilla Firebird (Win32), and not
MSIE. I originally thought this was a browser issue, but when I tried
the same code under CGI, all elements were successfully passed from both
Firebird and MSIE.
Upgrading from Firebird 0.7.1 to the latest nightly (dated 2003-11-12)
increased the number of passed form elements from approx. 269 to the
current 429. Strangely, f the form used method="GET" then all form
elements were passed regardless of browser type or version.
I am going to try to reproduce the problem under the most recent build
of mod_perl now.
If this can be narrowed down to mod_perl specifically, I'll make a more
formal bug report. I was wondering if anyone had seen anything like this
before.
Thanks,
y

Please disregard, the latest build (mod_perl-1.99_11) fixed the problem.

According to your report you are running 5.8.1:

I tested it with 5.8.0 and 5.8.1, but I can't get to reproduce it.
Do you get this problem if you run this test:
cd modperl-1.99-dev
t/TEST -v modperl/exit
run:
tail -F t/logs/error_log
in another console and see if you get this warnings. If not, please post a
very short handler which we can reproduce the problem with (ideally adjust
t/response/TestModperl/exit.pm to reproduce it).
