2021-01-25Merge branch 'dl/reflog-with-single-entry'Libravatar Junio C Hamano3-32/+63
After expiring a reflog and making a single commit, the reflog for the branch would record a single entry that knows both @{0} and @{1}, but we failed to answer "what commit were we on?", i.e. @{1} * dl/reflog-with-single-entry: refs: allow @{n} to work with n-sized reflog refs: factor out set_read_ref_cutoffs()
2021-01-25Merge branch 'sj/untracked-files-in-submodule-directory-is-not-dirty'Libravatar Junio C Hamano9-19/+42
"git diff" showed a submodule working tree with untracked cruft as "Submodule commit <objectname>-dirty", but a natural expectation is that the "-dirty" indicator would align with "git describe --dirty", which does not consider having untracked files in the working tree as source of dirtiness. The inconsistency has been fixed. * sj/untracked-files-in-submodule-directory-is-not-dirty: diff: do not show submodule with untracked files as "-dirty"

2021-01-14ci/install-depends: attempt to fix "brew cask" stuffLibravatar Junio C Hamano1-4/+4
We run "git pull" against "$cask_repo"; clarify that we are expecting not to have any of our own modifications and running "git pull" to merely update, by passing "--ff-only" on the command line. Also, the "brew cask install" command line triggers an error message that says: Error: Calling brew cask install is disabled! Use brew install [--cask] instead. In addition, "brew install caskroom/cask/perforce" step triggers an error that says: Error: caskroom/cask was moved. Tap homebrew/cask instead. Attempt to see if blindly following the suggestion in these error messages gets us into a better shape. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-01-12shortlog: remove unused(?) "repo-abbrev" featureLibravatar Ævar Arnfjörð Bjarmason9-56/+21
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. 1. 7595e2ee6ef (git-shortlog: make common repository prefix configurable with .mailmap, 2006-11-25) 2. fa375c7f1b6 (Add git-shortlog perl script, 2005-06-04) 3. https://lore.kernel.org/lkml/ 4. https://lore.kernel.org/lkml/alpine.LFD.1.00.0803161651350.3020@woody.linux-foundation.org/ 5. https://lore.kernel.org/lkml/BANLkTinrbh7Xi27an3uY7pDWrNKhJRYmEA@mail.gmail.com/ 6. https://lore.kernel.org/lkml/CAHk-=wg1+kf1AVzXA-RQX0zjM6t9J2Kay9xyuNqcFHWV-y5ZYw@mail.gmail.com/ Acked-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

This behavior was last discussed on the mailing list in the thread starting at [1].

2021-01-12mailmap doc + tests: add better examples & test themLibravatar Ævar Arnfjörð Bjarmason2-20/+117
Change the mailmap documentation added in 0925ce4d49 (Add map_user() and clear_mailmap() to mailmap, 2009-02-08) to continue discussing the Jane/Joe example. I think this makes things a lot less confusing as we're building up more complex examples using one set of data which covers all the things we'd like to discuss. Also add tests to assert that what our documentation says is what's actually happening. This is mostly (or entirely) covered by existing tests which I'm not deleting, but having these tests for the synopsis makes it easier to follow-along while reading the tests & docs.
