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.
