Description of problem:
There's a known bug in mod_perl-1.99_07 that ships with Redhat 9 that truncates
POST requests after the first 8192 characters.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Try this little script from inside Apache:

read (STDIN, $in, $ENV{'CONTENT_LENGTH'}); 
print "Content Length: $ENV{'CONTENT_LENGTH'}\n\n<P>\n"; 
print "Data Input: $in\n\n<P>\n"; 
print "Data Length: ", length $in; 

2.  Set apache directives 'SetHandler perl-script; PerlHandler
ModPerl::Registry::handler' to execute it from within mod_perl, and POST > 8192
bytes to it.

Actual Results:  You only get back the first 8192 bytes of whatever you POSTed.

Expected Results:  If you run it under apache directive 'SetHandler cgi-script'
(mod_cgi) it works like it should.  You get back the entire content of your POST.

Additional info:

It's a known bug in mod_perl.  Please provide a working mod_perl for Redhat 9
(or better still, Apache 1.3/mod_perl 1.2, which are generally known not to suck.)

http://perl.apache.org/dist/mod_perl-2.0-current/Changes - note the entry about
"fix the method content() in Apache::compat to read a whole request body."

mod_perl-1.99_09 is in Rawhide, please provide a Redhat 9 compatible version.

Please build yourself a copy of the one from rawhide.

This mod_perl bug is causing a lot of trouble on my websites.  It was subtle 
enough to slip by our testing, so we went ahead with upgrading the production 
sites to RH9.  Now, I've got piles of users complaining that their forum posts 
are being lost.  I did find a rawhide mod_perl-1.99_09 rpm, but it's not 
compatible, and I don't know how to "build yourself a copy of the one from 

I think it would be really helpful if Red Hat could build a RH9 compatible 
mod_perl-1.99_09 and put it into the update pipe.

Otherwise, I'm looking at bulding from source Perl/Apache/mod_perl/etc... to 
get this fixed.
