Hello!
I guess I've found a bug in mod_perl2.
I've run into troubles accessing the __DATA__ section of my
modules/handlers. A minimal demonstration handler looks like this:
#!/usr/bin/perl
package TestHandler;
sub handler {
warn tell DATA;
return 0;
}
1;
__DATA__
foobarbaz
Correct result without preloading of the module:
93 at /mnt/data/pro/konstrukt/dev/lib/TestHandler.pm line 4.
Incorrect result when preloading it with the Apache directive PerlModule
or in a script which is loaded by PerlRequire:
103 at /mnt/data/pro/konstrukt/dev/lib/TestHandler.pm line 4.
The cursor is positioned at the end of the file. On some larger files it
is often positioned somewhere in the middle of the DATA section.
These results are from the _first_ run after `apache2 restart` and I
have not read anything from DATA. I know that you have to store the
original DATA position on the first request, if you want to read from it
in multiple requests. But I don't read from DATA, the position is
already wrong before the first read.
My configuration details (Debian testing):
[EMAIL PROTECTED] dpkg -l | pcregrep '(libapache2-mod-perl2 |apache2 )'
ii apache2 2.0.55-4.1 [..]
ii libapache2-mod-perl2 2.0.2-2 [..]
[EMAIL PROTECTED] uname -a
Linux server.zentrifuge.intra 2.6.17 #1 PREEMPT Tue Jul 11 02:32:04

Same problem on Ubuntu Dapper:
ii apache2 2.0.55-4ubuntu2
ii libapache2-mod-perl2 2.0.2-2ubuntu1
Linux m1ndfuck 2.6.15-26-386 #1 PREEMPT Fri Jul 7 19:27:00 UTC 2006

The problem does not appear on my Apache1/mod_perl1 installation. It
also doesn't appear on Apache2/mod_perl2 using xampp/WindowsXP.
It also does not appear when using the preforking MPM. So there seems to
be a problem in this combination:
-Apache2/mod_perl2 with threaded MPM (or perchild MPM)
-Preloading the Perl module using 'PerlModule' or 'PerlRequire'
Best regards
