NAME
|
|
----
|
|
git-contacts - List people who might be interested in a set of changes
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git contacts' (<patch>|<range>|<rev>)...
|
|
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
Given a set of changes, specified as patch files or revisions, determine people
|
|
who might be interested in those changes. This is done by consulting the
|
|
history of each patch or revision hunk to find people mentioned by commits
|
|
which touched the lines of files under consideration.
|
|
|
|
Input consists of one or more patch files or revision arguments. A revision
|
|
argument can be a range or a single `<rev>` which is interpreted as
|
|
`<rev>..HEAD`, thus the same revision arguments are accepted as for
|
|
linkgit:git-format-patch[1]. Patch files and revision arguments can be combined
|
|
in the same invocation.
|
|
|
|
This command can be useful for determining the list of people with whom to
|
|
discuss proposed changes, or for finding the list of recipients to Cc: when
|
|
submitting a patch series via `git send-email`. For the latter case, `git
|
|
contacts` can be used as the argument to `git send-email`'s `--cc-cmd` option.
|
|
|
|
|
|
DISCUSSION
|
|
----------
|
|
|
|
`git blame` is invoked for each hunk in a patch file or revision. For each
|
|
commit mentioned by `git blame`, the commit message is consulted for people who
|
|
authored, reviewed, signed, acknowledged, or were Cc:'d. Once the list of
|
|
participants is known, each person's relevance is computed 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 exceed
|
|
a minimum threshold of participation.
|
|
|
|
|
|
OUTPUT
|
|
------
|
|
|
|
For each person of interest, a single line is output, terminated by a newline.
|
|
If the person's name is known, ``Name $$<user@host>$$'' is printed; otherwise
|
|
only ``$$<user@host>$$'' is printed.
|
|
|

EXAMPLES
|
|
--------
|
|
|
|
* Consult patch files:
|
|
+
|
|
------------
|
|
$ git contacts feature/*.patch
|
|
------------
|
|
|
|
* Revision range:
|
|
+
|
|
------------
|
|
$ git contacts R1..R2
|
|
------------
|
|
|
|
* From a single revision to `HEAD`:
|
|
+
|
|
------------
|
|
$ git contacts origin
|
|
------------
|
|
|
|
* Helper for `git send-email`:
|
|
+
|
|
------------
|
|
$ git send-email --cc-cmd='git contacts' feature/*.patch
|
|
------------
|
|
|
|
|
|
LIMITATIONS
|
|
-----------
|
|
|
|
Several conditions controlling a person's significance are currently
|
|
hard-coded, such as minimum participation level (10%), blame date-limiting (5
|
|
years), and `-C` level for detecting moved and copied lines (a single `-C`). In
|
|
the future, these conditions may become configurable.
