2013-07-21contrib: contacts: add documentationLibravatar Eric Sunshine1-0/+94
Assuming that git-contacts may some day be promoted to a core git command, the documentation is written and formatted as if it already belongs in Documentation/ even though it presently resides in contrib/contacts.

2013-07-21contrib: contacts: add mailmap supportLibravatar Eric Sunshine1-0/+18
The purpose of git-contacts is to determine a list of people who might have some interest in a patch or set of changes. It can be used as git-send-email's --cc-cmd argument or the computed list might be used to ask for comments on a proposed change. As such, it is important to report up-to-date email addresses in the computed list rather than potentially outdated ones recorded with commits. Apply git's mailmap functionality to the retrieved contacts in order to achieve this goal. Signed-off-by: Eric Sunshine <sunshine@sunshineco.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-07-21contrib: contacts: interpret committish akin to format-patchLibravatar Eric Sunshine1-1/+18
As a convenience, accept the same style <since> committish as accepted by git-format-patch. For example: % git contacts origin will consider commits in the current branch built atop 'origin', just as "git format-patch origin" will format commits built atop 'origin'.

2013-07-21contrib: contacts: add ability to parse from committishLibravatar Eric Sunshine1-6/+32
For example: % git contacts R1..R2 Committishes and patch files can be mentioned in the same invocation: % git contacts R1..R2 extra/*.patch Signed-off-by: Eric Sunshine <sunshine@sunshineco.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-07-21contrib: add git-contacts helperLibravatar Eric Sunshine1-0/+127
This script lists people that might be interested in a patch by going back through the history for each patch hunk, and finding people that reviewed, acknowledged, signed, authored, or were Cc:'d on 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 participants, it determines each person's relevance by considering how many commits mentioned that person compared with the total number of commits under consideration. The final output consists only of participants who pass a minimum threshold of participation. Several conditions controlling a person's significance are currently hard-coded, such as minimum participation level, blame date-limiting, and -C level for detecting moved and copied lines. In the future, these conditions may become configurable. For example: % git contacts 0001-remote-hg-trivial-cleanups.patch Felipe Contreras <felipe.contreras@gmail.com> Jeff King <peff@peff.net> Max Horn <max@quendi.de> Junio C Hamano <gitster@pobox.com> Thus, it can be invoked as git-send-email's --cc-cmd option, among other possible uses. This is a Perl rewrite of Felipe Contreras' git-related patch series[1] written in Ruby.
