Hi, 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 for.
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. For example: % 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 0460ed2 documentation: trivial style cleanups 126aac5 transport-helper: fix remote helper namespace regression 21610d8 transport-helper: clarify pushing without refspecs 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 be Cc'ed: % 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: --- expected 2013-10-10 21:13:45.938291298 +0000 +++ actual 2013-10-10 21:13:45.937291298 +0000 @@ -1,2 +1,2 @@ -Jon Stewart <j...@stewart.com> (author: 50%) -Pablo Escobar <pa...@escobar.com> (author: 50%) +Jon Stewart <j...@stewart.com> +Pablo Escobar <pa...@escobar.com> not ok 1 - basic git-contacts doesn't show the amount of involvement, but that's easy to fix. --- expected 2013-10-10 21:13:45.975291299 +0000 +++ actual 2013-10-10 21:13:45.974291299 +0000 @@ -1,2 +1,3 @@ -John Poppins <j...@doe.com> (author: 66%) -Jon Stewart <j...@stewart.com> (reviewer: 33%, author: 33%) +John Doe <j...@doe.com> +John Poppins <j...@doe.com> +Jon Stewart <j...@stewart.com> not ok 2 - others git-contacts doesn't show the kind of involvement (reviewer, author) nor does it group people by their email address. (skip other failures) expecting success: git related -craw -1 master | git log --format='%s' --no-walk --stdin > actual && cat > expected <<-EOF && four three one EOF test_cmp expected actual not ok 7 - commits 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 with "contacts". 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 :) Cheers.  http://article.gmane.org/gmane.comp.version-control.git/226058 -- Felipe Contreras -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
