2018-02-13Merge branch 'pw/sequencer-in-process-commit'Libravatar Junio C Hamano3-263/+34
The sequencer infrastructure is shared across "git cherry-pick", "git rebase -i", etc., and has always spawned "git commit" when it needs to create a commit. It has been taught to do so internally, when able, by reusing the codepath "git commit" itself uses, which gives performance boost for a few tens of percents in some sample scenarios. * pw/sequencer-in-process-commit: sequencer: run 'prepare-commit-msg' hook t7505: add tests for cherry-pick and rebase -i/-p t7505: style fixes sequencer: assign only free()able strings to gpg_sign sequencer: improve config handling t3512/t3513: remove KNOWN_FAILURE_CHERRY_PICK_SEES_EMPTY_COMMIT=1 sequencer: try to commit without forking 'git commit' sequencer: load commit related config sequencer: simplify adding Signed-off-by: trailer commit: move print_commit_summary() to libgit commit: move post-rewrite code to libgit Add a function to update HEAD after creating a commit commit: move empty message checks to libgit t3404: check intermediate squash messages

2018-01-24sequencer: run 'prepare-commit-msg' hookLibravatar Phillip Wood1-2/+0
Commit 356ee4659b ("sequencer: try to commit without forking 'git commit'", 2017-11-24) forgot to run the 'prepare-commit-msg' hook when creating the commit. Fix this by writing the commit message to a different file and running the hook. Using a different file means that if the commit is cancelled the original message file is unchanged. Also move the checks for an empty commit so the order matches 'git commit'.

2018-01-04diff: introduce DIFF_PICKAXE_KINDS_MASKLibravatar Stefan Beller1-2/+2
Currently the check whether to perform pickaxing is done via checking `diffopt->pickaxe`, which contains the command line argument that we want to pickaxe for. Soon we'll introduce a new type of pickaxing, that will not store anything in the `.pickaxe` field, so let's migrate the check to be dependent on pickaxe_opts. It is not enough to just replace the check for pickaxe by pickaxe_opts, because flags might be set, but pickaxing was not requested ('-i'). To cope with that, introduce a mask to check only for the bits indicating the modes of operation. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-01-03clone: do not clean up directories we didn't createLibravatar Jeff King1-4/+16
Once upon a time, git-clone would refuse to write into a directory that it did not itself create. The cleanup routines for a failed clone could therefore just remove the git and worktree dirs completely. In 55892d2398 (Allow cloning to an existing empty directory, 2009-01-11), we learned to write into an existing directory. Which means that doing: mkdir foo git clone will-fail foo ends up deleting foo. This isn't a huge catastrophe, since by definition foo must be empty. But it's somewhat confusing; we should leave the filesystem as we found it. Because we know that the only directory we'll write into is an empty one, we can handle this case by just passing the KEEP_TOPLEVEL flag to our recursive delete (if we could write into populated directories, we'd have to keep track of what we wrote and what we did not, which would be much harder). Note that we need to handle the work-tree and git-dir separately, though, as only one might exist (and the new tests in t5600 cover all cases).

2018-01-03clone: factor out dir_exists() helperLibravatar Jeff King1-3/+8
Two parts of git-clone's setup logic check whether a directory exists, and they both call stat directly with the same scratch "struct stat" buffer. Let's pull that into a helper, which has a few advantages: - it makes the purpose of the stat calls more obvious - it makes it clear that we don't care about the information in "buf" remaining valid - if we later decide to make the check more robust (e.g., complaining about non-directories), we can do it in one place Note that we could just use file_exists() for this, which has identical code. But we specifically care about directories, so this future-proofs us against that function later getting more picky about seeing actual files.

2017-12-28checkout: avoid using the rev_info flag leak_pendingLibravatar René Scharfe1-12/+1
The leak_pending flag is so awkward to use that multiple comments had to be added around each occurrence. We only use it for remembering the commits whose marks we have to clear after checking if the old HEAD is detached. This is easy, though: We need to do that for the old commit, the new one -- and for all refs. Don't bother tracking exactly which commits need their flags cleared, just nuke all we have in-core. This change is safe because refs can point at anything, so other program parts can't depend on any kept flags anyway. And since all refs are loaded we have to basically deal with all commits anyway, so performance should not be negatively impacted.

When 212945d4a85dfa172ea55ec73b1d830ef2d8582f ("Teach git-describe to verify annotated tag names before output") made Git favor the embedded name of annotated tags, it accidentally changed the output format when the --all flag is given, only printing the tag's name without the prefix.

2017-12-22commit: add support for --fixup <commit> -m"<extra message>"Libravatar Ævar Arnfjörð Bjarmason1-3/+5
Add support for supplying the -m option with --fixup. Doing so has errored out ever since --fixup was introduced. Before this, the only way to amend the fixup message while committing was to use --edit and amend it in the editor. The use-case for this feature is one of: * Leaving a quick note to self when creating a --fixup commit when it's not self-evident why the commit should be squashed without a note into another one. * (Ab)using the --fixup feature to "fix up" commits that have already been pushed to a branch that doesn't allow non-fast-forwards, i.e. just noting "this should have been part of that other commit", and if the history ever got rewritten in the future the two should be combined. In such a case you might want to leave a small message, e.g. "forgot this part, which broke XYZ". With this, --fixup <commit> -m"More" -m"Details" will result in a commit message like: !fixup <subject of <commit>> More Details The reason the test being added here seems to squash "More" at the end of the subject line of the commit being fixed up is because the test code is using "%s%b" so the body immediately follows the subject, it's not a bug in this code, and other tests t7500-commit.sh do the same thing. When the --fixup option was initially added the "Option -m cannot be combined" error was expanded from -c, -C and -F to also include --fixup[1] Those options could also support combining with -m, but given what they do I can't think of a good use-case for doing that, so I have not made the more invasive change of splitting up the logic in commit.c to first act on those, and then on -m options. 1. d71b8ba7c9 ("commit: --fixup option for use with rebase --autosquash", 2010-11-02) Helped-by: Eric Sunshine <sunshine@sunshineco.com> Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-12-19builtin/describe.c: describe a blobLibravatar Stefan Beller1-5/+57
Sometimes users are given a hash of an object and they want to identify it further (ex.: Use verify-pack to find the largest blobs, but what are these? or [1]) When describing commits, we try to anchor them to tags or refs, as these are conceptually on a higher level than the commit. And if there is no ref or tag that matches exactly, we're out of luck. So we employ a heuristic to make up a name for the commit. These names are ambiguous, there might be different tags or refs to anchor to, and there might be different path in the DAG to travel to arrive at the commit precisely. When describing a blob, we want to describe the blob from a higher layer as well, which is a tuple of (commit, deep/path) as the tree objects involved are rather uninteresting. The same blob can be referenced by multiple commits, so how we decide which commit to use? This patch implements a rather naive approach on this: As there are no back pointers from blobs to commits in which the blob occurs, we'll start walking from any tips available, listing the blobs in-order of the commit and once we found the blob, we'll take the first commit that listed the blob. For example git describe --tags v0.99:Makefile conversion-901-g7672db20c2:Makefile tells us the Makefile as it was in v0.99 was introduced in commit 7672db20. The walking is performed in reverse order to show the introduction of a blob rather than its last occurrence.

Prior to commit a2d725b7bdf7 ("Use an external program to implement fetching with curl", 2009-08-05), if Git was compiled with NO_CURL, the get_refs_list and fetch methods in struct transport might not be populated, hence the checks in clone and fetch. After that commit, all transports populate get_refs_list and fetch, making the checks in clone and fetch redundant. Remove those checks.
