* | cherry-pick: don't forget -s on failureMiklos Vajna2012-09-141-0/+65
|/ | | | | | | | | | | | | | | In case 'git cherry-pick -s <commit>' failed, the user had to use 'git commit -s' (i.e. state the -s option again), which is easy to forget about. Instead, write the signed-off-by line early, so plain 'git commit' will have the same result. Also update 'git commit -s', so that in case there is already a relevant Signed-off-by line before the Conflicts: line, it won't add one more at the end of the message. If there is no such line, then add it before the the Conflicts: line. Signed-off-by: Miklos Vajna <vmiklos@suse.cz> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When giving multiple individual revisions to cherry-pick or revert, as in 'git cherry-pick A B' or 'git revert B A', one would expect them to be picked/reverted in the order given on the command line. They are instead ordered by their commit timestamp -- in chronological order for "cherry-pick" and in reverse chronological order for "revert". This matches the order in which one would usually give them on the command line, making this bug somewhat hard to notice. Still, it has been reported at least once before [1]. It seems like the chronological sorting happened by accident because the revision walker has traditionally always sorted commits in reverse chronological order when rev_info.no_walk was enabled. In the case of 'git revert B A' where B is newer than A, this sorting is a no-op. For 'git cherry-pick A B', the sorting would reverse the arguments, but because the sequencer also flips the rev_info.reverse flag when picking (as opposed to reverting), the end result is a chronological order. The rev_info.reverse flag was probably flipped so that the revision walker emits B before C in 'git cherry-pick A..C'; that it happened to effectively undo the unexpected sorting done when not walking, was probably a coincidence that allowed this bug to happen at all. Fix the bug by telling the revision walker not to sort the commits when not walking. The only case we want to reverse the order is now when cherry-picking and walking revisions (rev_info.no_walk = 0).

* | cherry-pick: add --allow-empty-message optionChris Webb2012-08-061-0/+3
|/ | | | | | | | | | | | | Scripts such as "git rebase -i" cannot currently cherry-pick commits which have an empty commit message, as git cherry-pick calls git commit without the --allow-empty-message option. Add an --allow-empty-message option to git cherry-pick which is passed through to git commit, so this behaviour can be overridden.

| | | | | | | | | | | | | | | | | | | | | | | | The earlier "--keep-redundant-commit" series broke "cherry-pick" that is given a commit whose change is already in the current history. Such a cherry-pick would result in an empty change, and should stop with an error, telling the user that conflict resolution may have made the result empty (which is exactly what is happening), but we silently dropped the change on the floor without any message nor non-zero exit code.

| | | | | | | | | | | | | | | | | | | | | | | | | | In the case the pointer could be NULL, the function that gave the caller the NULL pointer would already have issued an error message, so simply returning early with an error status without issuing a new message is sufficient. The same for parse_commit() that will show necessary error message when the argument is not NULL, and will return error silently when the argument is NULL.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The git-cherry-pick --allow-empty command by default only preserves empty commits that were originally empty, i.e only those commits for which <commit>^{tree} and <commit>^^{tree} are equal. By default commits which are non-empty, but were made empty by the inclusion of a prior commit on the current history are filtered out. This option allows us to override that behavior and include redundant commits as empty commits in the change history. Note that this patch changes the default behavior of git cherry-pick slightly. Prior to this patch all commits in a cherry-pick sequence were applied and git commit was run. The implication here was that, if a commit was redundant, and the commit did not trigger the fast forward logic, the git commit operation, and therefore the git cherry-pick operation would fail, displaying the cherry pick advice (i.e. run git commit --allow-empty). With this patch however, such redundant commits are automatically skipped without stopping, unless --keep-redundant-commits is specified, in which case, they are automatically applied as empty commits.

| * git-cherry-pick: add allow-empty optionNeil Horman2012-04-111-2/+5
| | | | | | | | | | | | | | | | | | | | | | git cherry-pick fails when picking a non-ff commit that is empty. The advice given with the failure is that a git-commit --allow-empty should be issued to explicitly add the empty commit during the cherry pick. This option allows a user to specify before hand that they want to keep the empty commit. This eliminates the need to issue both a cherry pick and a commit operation.

| | | | | | | | | | | | | | | | | | | | When cherry-pick fails it offers a helpful hint about how to proceed. The hint tells the user how to do the cleanup needed by the conflicted cherry-pick and finish the job after conflict resolution. In case of cherry-pick --no-commit, the hint goes too far. It tells the user to finish up with 'git commit'. That is not what this git-cherry-pick was trying to do in the first place. Restrict the hint in case of --no-commit to avoid giving this extra advice. Also, add a test verifying the reduced hint for the --no-commit version of cherry-pick.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | Expose the cherry-picking machinery through a public sequencer_pick_revisions() (renamed from pick_revisions() in builtin/revert.c), so that cherry-picking and reverting are special cases of a general sequencer operation. The cherry-pick builtin is now a thin wrapper that does command-line argument parsing before calling into sequencer_pick_revisions(). In the future, we can write a new "foo" builtin that calls into the sequencer like: memset(&opts, 0, sizeof(opts)); opts.action = REPLAY_FOO; opts.revisions = xmalloc(sizeof(*opts.revs)); parse_args_populate_opts(argc, argv, &opts); init_revisions(opts.revs); sequencer_pick_revisions(&opts); This patch does not intend to make any functional changes.

* revert: Introduce --reset to remove sequencer stateRamkumar Ramachandra2011-08-041-0/+19
To explicitly remove the sequencer state for a fresh cherry-pick or revert invocation, introduce a new subcommand called "--reset" to remove the sequencer state. Take the opportunity to publicly expose the sequencer paths, and a generic function called "remove_sequencer_state" that various git programs can use to remove the sequencer state in a uniform manner; "git reset" uses it later in this series. Introducing this public API is also in line with our long-term goal of eventually factoring out functions from revert.c into a generic commit sequencer.
