How to Contribute
Help with mod_perl is always welcome. You do not have to know any code to help out - we also need help testing, answering questions, improving documentation, etc.
Issues
Bugs and problems can be reported at:
https://rt.cpan.org/Dist/Display.html?Name=mod_perl
which can be accessed from the "Issues" link in the left-hand menu on the metacpan.org page, https://metacpan.org/pod/mod_perl2 .
(Note: You will need to log in to https://rt.cpan.org in order to get the "Report a new bug" button on the bug tracker page.)
Discussions
There is a low-volume mailing list for mod_perl users and developers to share ideas, solve problems and discuss things related to mod_perl and the Apache::* modules.
Send an email to modperl@perl.apache.org. Before doing so, you should subscribe by sending an email to modperl-subscribe@perl.apache.org. Send an email to modperl-unsubscribe@perl.apache.org to unsubscribe.
There is also a low-volume mailing list for discussions about the development of the core mod_perl.
Send an email to dev@perl.apache.org. Before doing so, you should subscribe by sending an email to dev-subscribe@perl.apache.org. Send an email to dev-unsubscribe@perl.apache.org to unsubscribe.
Testing
You can help by testing mod_perl as widely as possible. Running the tests on a wide variety of platforms, Apache httpd versions, Perl versions and other factors is a great help in uncovering problems and improving mod_perl.
Code development
Development happens in a Subversion repo. The canonical location is currently at:
https://svn.apache.org/repos/asf/perl/
The current mod_perl 2.0 development branch is at modperl/trunk under the above URL.
Create your own copy of that branch by running:
svn co https://svn.apache.org/repos/asf/perl/modperl/trunk/ mod_perl2
