Remove support for the magical "repo-abbrev" comment in .mailmap
files. This was added to .mailmap parsing in [1], as a generalized
feature of the git-shortlog Perl script added earlier in [2].
There was no documentation or tests for this feature, and I don't
think it's used in practice anymore.
What it did was to allow you to specify a single string to be
search-replaced with "/.../" in the .mailmap file. E.g. for
linux.git's current .mailmap:
git archive --remote=git@gitlab.com:linux-kernel/linux.git \
HEAD -- .mailmap | grep -a repo-abbrev
# repo-abbrev: /pub/scm/linux/kernel/git/
Then when running e.g.:
git shortlog --merges --author=Linus -1 v5.10-rc7..v5.10 | grep Merge
We'd emit (the [...] is mine):
Merge tag [...]git://git.kernel.org/.../tip/tip
But will now emit:
Merge tag [...]git.kernel.org/pub/scm/linux/kernel/git/tip/tip
I think at this point this is just a historical artifact we can get
rid of. It was initially meant for Linus's own use when we integrated
the Perl script[2], but since then it seems he's stopped using it.
Digging through Linus's release announcements on the LKML[3] the last
release I can find that made use of this output is Linux 2.6.25-rc6
back in March 2008[4]. Later on Linus started using --no-merges[5],
and nowadays seems to prefer some custom not-quite-shortlog format of
merges from lieutenants[6].
You will still see it on linux.git if you run "git shortlog" manually
yourself with --merges, with this removed you can still get the same
output with:
git log --pretty=fuller v5.10-rc7..v5.10 |
sed 's!/pub/scm/linux/kernel/git/!/.../!g' |
git shortlog
Arguably we should do the same for the search-replacing of "[PATCH]"
at the beginning with "". That seems to be another relic of a bygone
era when linux.git patches would have their E-Mail subject lines
applied as-is by "git am" or whatever. But we documented that feature
in "git-shortlog(1)", and it seems more widely applicable than
something purely kernel-specific.

Now that shortlog supports reading from trailers, it can be useful to
combine counts from multiple trailers, or between trailers and authors.
This can be done manually by post-processing the output from multiple
runs, but it's non-trivial to make sure that each name/commit pair is
counted only once.
This patch teaches shortlog to accept multiple --group options on the
command line, and pull data from all of them. That makes it possible to
run:
git shortlog -ns --group=author --group=trailer:co-authored-by
to get a shortlog that counts authors and co-authors equally.
The implementation is mostly straightforward. The "group" enum becomes a
bitfield, and the trailer key becomes a list. I didn't bother
implementing the multi-group semantics for reading from stdin. It would
be possible to do, but the existing matching code makes it awkward, and
I doubt anybody cares.
The duplicate suppression we used for trailers now covers authors and
committers as well (though in non-trailer single-group mode we can skip
the hash insertion and lookup, since we only see one value per commit).
There is one subtlety: we now care about the case when no group bit is
set (in which case we default to showing the author). The caller in
builtin/log.c needs to be adapted to ask explicitly for authors, rather
than relying on shortlog_init(). It would be possible with some
gymnastics to make this keep working as-is, but it's not worth it for a
single caller.

If a project uses commit trailers, this patch lets you use
shortlog to see who is performing each action. For example,
running:
git shortlog -ns --group=trailer:reviewed-by
in git.git shows who has reviewed. You can even use a custom
format to see things like who has helped whom:
git shortlog --format="...helped %an (%ad)" \
--group=trailer:helped-by

In preparation for adding more grouping types, let's refactor the
committer/author grouping code and add a user-facing option that binds
them together. In particular:
- the main option is now "--group", to make it clear
that the various group types are mutually exclusive. The
"--committer" option is an alias for "--group=committer".
- we keep an enum rather than a binary flag, to prepare
for more values
- we prefer switch statements to ternary assignment, since
other group types will need more custom code

I looped over the toplevel header files, creating a temporary two-line C
program for each consisting of
#include "git-compat-util.h"
#include $HEADER
This patch is the result of manually fixing errors in compiling those
tiny programs.

In some situations you may want to group the commits not by author,
but by committer instead.
For example, when I just wanted to look up what I'm still missing from
linux-next in the current merge window, I don't care so much about who
wrote a patch, as what git tree it came from, which generally boils
down to "who committed it".
So make git shortlog take a "-c" or "--committer" option to switch
grouping to that.

The name path_list was correct for the first usage of that data structure,
but it really is a general-purpose string list.
$ perl -i -pe 's/path-list/string-list/g' $(git grep -l path-list)
$ perl -i -pe 's/path_list/string_list/g' $(git grep -l path_list)
$ git mv path-list.h string-list.h
$ git mv path-list.c string-list.c
$ perl -i -pe 's/has_path/has_string/g' $(git grep -l has_path)
$ perl -i -pe 's/path/string/g' string-list.[ch]
$ git mv Documentation/technical/api-path-list.txt \
Documentation/technical/api-string-list.txt
$ perl -i -pe 's/strdup_paths/strdup_strings/g' $(git grep -l strdup_paths)
... and then fix all users of string-list to access the member "string"
instead of "path".
Documentation/technical/api-string-list.txt needed some rewrapping, too.

With this patch, the user can override the default setting, to print
the commit messages using a user format instead of the onelines of the
commits. Example:
$ git shortlog --pretty='format:%s (%h)' <commit>..
Note that shortlog will only respect a user format setting, as the other
formats do not make much sense.
Wished for by Andrew Morton.

Shortlog is gives a pretty simple API for cases where you're already
identifying all of the individual commits. Make this available to
other code instead of requiring them to use the revision API and
command line.
