Neil Horman	b27cfb0d8d	git-cherry-pick: Add keep-redundant-commits option 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.

Neil Horman	df478b744c	git-cherry-pick: add allow-empty option 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.

Ramkumar Ramachandra	043a4492b3	sequencer: factor code out of revert builtin 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.

Jonathan Nieder	d596118d7a	revert: stop creating and removing sequencer-old directory Now that "git reset" no longer implicitly removes .git/sequencer that the operator may or may not have wanted to keep, the logic to write a backup copy of .git/sequencer and remove it when stale is not needed any more. Simplify the sequencer API and repository layout by dropping it. Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	13 years ago
Jonathan Nieder	f80a87262a	revert: rename --reset option to --quit The option to "git cherry-pick" and "git revert" to discard the sequencer state introduced by v1.7.8-rc0~141^2~6 (revert: Introduce --reset to remove sequencer state, 2011-08-04) has a confusing name. Change it now, while we still have the time. The new name for "cherry-pick, please get out of my way, since I've long forgotten about the sequence of commits I was cherry-picking when you wrote that old .git/sequencer directory" is --quit. Mnemonic: this is analagous to quiting a program the user is no longer using --- we just want to get out of the multiple-command cherry-pick procedure and not to reset HEAD or rewind any other old state. The "--reset" option is kept as a synonym to minimize the impact. We might consider dropping it for simplicity in a separate patch, though. Adjust documentation and tests to use the newly preferred name (--quit) instead of --reset. While at it, let's clarify the short descriptions of these operations in "-h" output. Before: --reset forget the current operation --continue continue the current operation After: --quit end revert or cherry-pick sequence --continue resume revert or cherry-pick sequence Noticed-by: Phil Hord <phil.hord@gmail.com> Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	13 years ago
Ramkumar Ramachandra	26ae337be1	revert: Introduce --reset to remove sequencer state 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.
