libs: use "struct repository *" argument, not "the_repository" As can easily be seen from grepping in our sources, we had these uses of "the_repository" in various library code in cases where the function in question was already getting a "struct repository *" argument. Let's use that argument instead. Out of these changes only the changes to "cache-tree.c", "commit-reach.c", "shallow.c" and "upload-pack.c" would have cleanly applied before the migration away from the "repo_*()" wrapper macros in the preceding commits. The rest aren't new, as we'd previously implicitly refer to "the_repository", but it's now more obvious that we were doing the wrong thing all along, and should have used the parameter instead. The change to change "get_index_format_default(the_repository)" in "read-cache.c" to use the "r" variable instead should arguably have been part of [1], or in the subsequent cleanup in [2]. Let's do it here, as can be seen from the initial code in [3] it's not important that we use "the_repository" there, but would prefer to always use the current repository. This change excludes the "the_repository" use in "upload-pack.c"'s upload_pack_advertise(), as the in-flight [4] makes that change. 1. ee1f0c242ef (read-cache: add index.skipHash config option, 2023-01-06) 2. 6269f8eaad0 (treewide: always have a valid "index_state.repo" member, 2023-01-17) 3. 7211b9e7534 (repo-settings: consolidate some config settings, 2019-08-13) 4. <Y/hbUsGPVNAxTdmS@coredump.intra.peff.net> Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

C style: use standard style for "TRANSLATORS" comments Change all the "TRANSLATORS: [...]" comments in the C code to use the regular Git coding style, and amend the style guide so that the example there uses that style. This custom style was necessary back in 2010 when the gettext support was initially added, and was subsequently documented in commit cbcfd4e3ea ("i18n: mention "TRANSLATORS:" marker in Documentation/CodingGuidelines", 2014-04-18). GNU xgettext hasn't had the parsing limitation that necessitated this exception for almost 3 years. Since its 0.19 release on 2014-06-02 it's been able to recognize TRANSLATOR comments in the standard Git comment syntax[1]. Usually we'd like to keep compatibility with software that's that young, but in this case literally the only person who needs to be using a gettext newer than 3 years old is Jiang Xin (the only person who runs & commits "make pot" results), so I think in this case we can make an exception. This xgettext parsing feature was added after a thread on the Git mailing list[2] which continued on the bug-gettext[3] list, but we never subsequently changed our style & styleguide, do so. There are already longstanding changes in git that use the standard comment style & have their TRANSLATORS comments extracted properly without getting the literal "*"'s mixed up in the text, as would happen before xgettext 0.19. Commit 7ff2683253 ("builtin-am: implement -i/--interactive", 2015-08-04) added one such comment, which in commit df0617bfa7 ("l10n: git.pot: v2.6.0 round 1 (123 new, 41 removed)", 2015-09-05) got picked up in the po/git.pot file with the right format, showing that Jiang already runs a modern xgettext. The xgettext parser does not handle the sort of non-standard comment style that I'm amending here in sequencer.c, but that isn't standard Git comment syntax anyway. With this change to sequencer.c & "make pot" the comment in the pot file is now correct: #. TRANSLATORS: %s will be "revert", "cherry-pick" or -#. * "rebase -i". +#. "rebase -i". 1. http://git.savannah.gnu.org/cgit/gettext.git/commit/?id=10af7fe6bd 2. <2ce9ec406501d112e032c8208417f8100bed04c6.1397712142.git.worldhello.net@gmail.com> (https://public-inbox.org/git/2ce9ec406501d112e032c8208417f8100bed04c6.1397712142.git.worldhello.net@gmail.com/) 3. https://lists.gnu.org/archive/html/bug-gettext/2014-04/msg00016.html Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Acked-by: Jiang Xin <worldhello.net@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
