Getting Help with mod_perl 2.0 Core Development


This document covers the resources available to the mod_perl 2.0 core developer. Please notice that you probably want to read the user's help documentation if you have problems using mod_perl 2.0.

The following mailing lists and resources can be of a major interest to the mod_perl 2.0 developers.


Submitting Patches

If you submit patches the Porting/patching.pod manpage can be very useful. You can find it perl-5.7.0/Porting/patching.pod or similar or read it online at

Note that we prefer the patches inlined into an email. This makes easier to comment on them. If your email client mangles the spacing and wraps lines, then send them as MIME attachments.
