This is basically the same as my original series which was dropped
for no good reasons, plus all the other features I also sent patches
This is way superior to the current git-contacts that sits on the contrib area.
For the uninitiated, this tool finds people that might be interested
in a patch, by going back through the history for each single hunk
modified, and finding people that reviewed, acknowledged, signed, or
authored the code the patch is modifying.
It does this by running `git blame` incrementally on each hunk, and
then parsing the commit message. After gathering all the relevant
people, it groups them to show what exactly was their role when the
participated in the development of the relevant commit, and on how
many relevant commits they participated. They are only displayed if
they pass a minimum threshold of participation.
% git related master..fc/transport/improv
Junio C Hamano <gits...@pobox.com> (signer: 90%, author: 5%)
Felipe Contreras <felipe.contre...@gmail.com> (author: 25%, reviewer: 2%)
Sverre Rabbelier <srabbel...@gmail.com> (author: 17%, acker: 2%, signer: 7%)
Jeff King <p...@peff.net> (acker: 17%, author: 10%)
Shawn O. Pearce <spea...@spearce.org> (author: 5%, signer: 2%, cced: 2%)
Elijah Newren <new...@gmail.com> (author: 10%)
In addition, it has an option to output the list of commits, instead
of the contributors, which allows you to easily find out the previous
changes to the lines your patches modify.
% git related -c master..fc/transport/improv
99d9ec0 Merge branch 'fc/transport-helper-no-refspec'
67c9c78 transport-helper: barf when user tries old:new

a93b4a0 transport-helper: warn when refspec is not used
664059f transport-helper: update remote helper namespace
c4458ec fast-export: Allow pruned-references in mark file
Moreover, when sending patches for review, you can configure `git
send-email` to use `git related` to find relevant people that should
% git send-email --cc-cmd='git related' *.patch
It has way many more features than git-contacts which is a rewrite in
Perl of this script, but only the initial bare minimum stage.
I've also added tests, and this is how git-contacts fares in comparison:

git-contacts doesn't show the kind of involvement (reviewer, author)
nor does it group people by their email address.

Also, it doesn't have the option to show the commits themselves, which
is useful to investigate the diffs. This feature alone is what makes
the make "git-contacts" not appropriate, because if this feature is
implemented, 'git contacts --commits' wouldn't have anything to do
For that matter it doesn't support any options at all (e.g.
--min-percent, --since), and doesn't have a usage helper (--help).
Just put git-related in your PATH, and enjoy :)
