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>

git notes merge: Manual conflict resolution, part 2/2 When the notes merge conflicts in .git/NOTES_MERGE_WORKTREE have been resolved, we need to record a new notes commit on the appropriate notes ref with the resolved notes. This patch implements 'git notes merge --commit' which the user should run after resolving conflicts in the notes merge worktree. This command finalizes the notes merge by recombining the partial notes tree from part 1 with the now-resolved conflicts in the notes merge worktree in a merge commit, and updating the appropriate ref to this merge commit. In order to correctly finalize the merge, we need to keep track of three things: - The partial merge result from part 1, containing the auto-merged notes. This is now stored into a ref called .git/NOTES_MERGE_PARTIAL. - The unmerged notes. These are already stored in .git/NOTES_MERGE_WORKTREE, thanks to part 1. - The notes ref to be updated by the finalized merge result. This is now stored in a symref called .git/NOTES_MERGE_REF. In addition to "git notes merge --commit", which uses the above details to create the finalized notes merge commit, this patch also implements "git notes merge --reset", which aborts the ongoing notes merge by simply removing the files/directory described above. FTR, "git notes merge --commit" reuses "git notes merge --reset" to remove the information described above (.git/NOTES_MERGE_*) after the notes merge have been successfully finalized. The patch also contains documentation and testcases for the two new options.

git notes merge: Handle real, non-conflicting notes merges This continuation of the 'git notes merge' implementation teaches notes-merge to properly do real merges between notes trees: Two diffs are performed, one from $base to $remote, and another from $base to $local. The paths in each diff are normalized to SHA1 object names. The two diffs are then consolidated into a single list of change pairs to be evaluated. Each change pair consist of: - The annotated object's SHA1 - The $base SHA1 (i.e. the common ancestor notes for this object) - The $local SHA1 (i.e. the current notes for this object) - The $remote SHA1 (i.e. the to-be-merged notes for this object) From the pair ($base -> $local, $base -> $remote), we can determine the merge result using regular 3-way rules. If conflicts are encountered in this process, we fail loudly and exit (conflict handling to be added in a future patch), If we can complete the merge without conflicts, the resulting notes tree is committed, and the current notes ref updated. The patch includes added testcases verifying that we can successfully do real conflict-less merges. This patch has been improved by the following contributions: - Jonathan Nieder: Future-proof by always checking add_note() return value - Stephen Boyd: Use test_commit - Jonathan Nieder: Use trace_printf(...) instead of OUTPUT(o, 5, ...) - Junio C Hamano: fixup minor style issues Thanks-to: Jonathan Nieder <jrnieder@gmail.com> Thanks-to: Stephen Boyd <bebarino@gmail.com> Thanks-to: Junio C Hamano <gitster@pobox.com> Signed-off-by: Johan Herland <johan@herland.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

git notes merge: Manual conflict resolution, part 2/2 When the notes merge conflicts in .git/NOTES_MERGE_WORKTREE have been resolved, we need to record a new notes commit on the appropriate notes ref with the resolved notes. This patch implements 'git notes merge --commit' which the user should run after resolving conflicts in the notes merge worktree. This command finalizes the notes merge by recombining the partial notes tree from part 1 with the now-resolved conflicts in the notes merge worktree in a merge commit, and updating the appropriate ref to this merge commit. In order to correctly finalize the merge, we need to keep track of three things: - The partial merge result from part 1, containing the auto-merged notes. This is now stored into a ref called .git/NOTES_MERGE_PARTIAL. - The unmerged notes. These are already stored in .git/NOTES_MERGE_WORKTREE, thanks to part 1. - The notes ref to be updated by the finalized merge result. This is now stored in a symref called .git/NOTES_MERGE_REF. In addition to "git notes merge --commit", which uses the above details to create the finalized notes merge commit, this patch also implements "git notes merge --reset", which aborts the ongoing notes merge by simply removing the files/directory described above. FTR, "git notes merge --commit" reuses "git notes merge --reset" to remove the information described above (.git/NOTES_MERGE_*) after the notes merge have been successfully finalized. The patch also contains documentation and testcases for the two new options.

git notes merge: Handle real, non-conflicting notes merges This continuation of the 'git notes merge' implementation teaches notes-merge to properly do real merges between notes trees: Two diffs are performed, one from $base to $remote, and another from $base to $local. The paths in each diff are normalized to SHA1 object names. The two diffs are then consolidated into a single list of change pairs to be evaluated. Each change pair consist of: - The annotated object's SHA1 - The $base SHA1 (i.e. the common ancestor notes for this object) - The $local SHA1 (i.e. the current notes for this object) - The $remote SHA1 (i.e. the to-be-merged notes for this object) From the pair ($base -> $local, $base -> $remote), we can determine the merge result using regular 3-way rules. If conflicts are encountered in this process, we fail loudly and exit (conflict handling to be added in a future patch), If we can complete the merge without conflicts, the resulting notes tree is committed, and the current notes ref updated. The patch includes added testcases verifying that we can successfully do real conflict-less merges. This patch has been improved by the following contributions: - Jonathan Nieder: Future-proof by always checking add_note() return value - Stephen Boyd: Use test_commit - Jonathan Nieder: Use trace_printf(...) instead of OUTPUT(o, 5, ...) - Junio C Hamano: fixup minor style issues Thanks-to: Jonathan Nieder <jrnieder@gmail.com> Thanks-to: Stephen Boyd <bebarino@gmail.com> Thanks-to: Junio C Hamano <gitster@pobox.com> Signed-off-by: Johan Herland <johan@herland.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

git notes merge: Handle real, non-conflicting notes merges This continuation of the 'git notes merge' implementation teaches notes-merge to properly do real merges between notes trees: Two diffs are performed, one from $base to $remote, and another from $base to $local. The paths in each diff are normalized to SHA1 object names. The two diffs are then consolidated into a single list of change pairs to be evaluated. Each change pair consist of: - The annotated object's SHA1 - The $base SHA1 (i.e. the common ancestor notes for this object) - The $local SHA1 (i.e. the current notes for this object) - The $remote SHA1 (i.e. the to-be-merged notes for this object) From the pair ($base -> $local, $base -> $remote), we can determine the merge result using regular 3-way rules. If conflicts are encountered in this process, we fail loudly and exit (conflict handling to be added in a future patch), If we can complete the merge without conflicts, the resulting notes tree is committed, and the current notes ref updated. The patch includes added testcases verifying that we can successfully do real conflict-less merges. This patch has been improved by the following contributions: - Jonathan Nieder: Future-proof by always checking add_note() return value - Stephen Boyd: Use test_commit - Jonathan Nieder: Use trace_printf(...) instead of OUTPUT(o, 5, ...) - Junio C Hamano: fixup minor style issues Thanks-to: Jonathan Nieder <jrnieder@gmail.com> Thanks-to: Stephen Boyd <bebarino@gmail.com> Thanks-to: Junio C Hamano <gitster@pobox.com> Signed-off-by: Johan Herland <johan@herland.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
