The `--no-walk` flag supports two modes: either it sorts the revisions
given as input input or it doesn't. This is reflected in a single
`no_walk` flag, which reflects one of the three states "walk", "don't
walk but without sorting" and "don't walk but with sorting".
Split up the flag into two separate bits, one indicating whether we
should walk or not and one indicating whether the input should be sorted
or not. This will allow us to more easily introduce a new flag
`--unsorted-input`, which only impacts the sorting bit.

save_opts() should save any non-default values. It was intended to do
this, but since most options in struct replay_opts default to 0, it only
saved non-zero values. Unfortunately, this does not always work for
options.edit. Roughly speaking, options.edit had a default value of 0
for cherry-pick but a default value of 1 for revert. Make save_opts()
record a value whenever it differs from the default.
options.edit was also overly simplistic; we had more than two cases.
The behavior that previously existed was as follows:
Non-conflict commits Right after Conflict
revert Edit iff isatty(0) Edit (ignore isatty(0))
cherry-pick No edit See above
Specify --edit Edit (ignore isatty(0)) See above
Specify --no-edit (*) See above
(*) Before stopping for conflicts, No edit is the behavior. After
stopping for conflicts, the --no-edit flag is not saved so see
the first two rows.
However, the expected behavior is:
Non-conflict commits Right after Conflict
revert Edit iff isatty(0) Edit iff isatty(0)
cherry-pick No edit Edit iff isatty(0)
Specify --edit Edit (ignore isatty(0)) Edit (ignore isatty(0))
Specify --no-edit No edit No edit
In order to get the expected behavior, we need to change options.edit
to a tri-state: unspecified, false, or true. When specified, we follow
what it says. When unspecified, we need to check whether the current
commit being created is resolving a conflict as well as consulting
options.action and isatty(0). While at it, add a should_edit() utility
function that compresses options.edit down to a boolean based on the
additional information for the non-conflict case.
continue_single_pick() is the function responsible for resuming after
conflict cases, regardless of whether there is one commit being picked
or many. Make this function stop assuming edit behavior in all cases,
so that it can correctly handle !isatty(0) and specific requests to not
edit the commit message.

Allow the testsuite to run where it treats requests for "recursive" or
the default merge algorithm via consulting the environment variable
GIT_TEST_MERGE_ALGORITHM which is expected to either be "recursive" (the
old traditional algorithm) or "ort" (the new algorithm).
Also, allow folks to pick the new algorithm via config setting. It
turns out builtin/merge.c already had a way to allow users to specify a
different default merge algorithm: pull.twohead. Rather odd
configuration name (especially to be in the 'pull' namespace rather than
'merge') but it's there. Add that same configuration to rebase,
cherry-pick, and revert.
This required updating the various callsites that called merge_trees()
or merge_recursive() to conditionally call the new API, so this serves
as another demonstration of what the new API looks and feels like.
There are almost certainly some callsites that have not yet been
modified to work with the new merge algorithm, but this represents the
ones that I have been testing with thus far.

Ted reported an old typo in the git-commit.txt and merge-options.txt.
Namely, the phrase "Signed-off-by line" was used without either a
definite nor indefinite article.
Upon examination, it seems that the documentation (including items in
Documentation/, but also option help strings) have been quite
inconsistent on usage when referring to `Signed-off-by`.
First, very few places used a definite or indefinite article with the
phrase "Signed-off-by line", but that was the initial typo that led
to this investigation. So, normalize using either an indefinite or
definite article consistently.
The original phrasing, in Commit 3f971fc425 (Documentation updates,
2005-08-14), is "Add Signed-off-by line". Commit 6f855371a5 (Add
--signoff, --check, and long option-names. 2005-12-09) switched to
using "Add `Signed-off-by:` line", but didn't normalize the former
commit to match. Later commits seem to have cut and pasted from one
or the other, which is likely how the usage became so inconsistent.
Junio stated on the git mailing list in
<xmqqy2k1dfoh.fsf@gitster.c.googlers.com> a preference to leave off
the colon. Thus, prefer `Signed-off-by` (with backticks) for the
documentation files and Signed-off-by (without backticks) for option
help strings.
Additionally, Junio argued that "trailer" is now the standard term to
refer to `Signed-off-by`, saying that "becomes plenty clear that we
are not talking about any random line in the log message". As such,
prefer "trailer" over "line" anywhere the former word fits.
However, leave alone those few places in documentation that use
Signed-off-by to refer to the process (rather than the specific
trailer), or in places where mail headers are generally discussed in
comparison with Signed-off-by.

git am or rebase have a --skip flag to skip the current commit if the
user wishes to do so. During a cherry-pick or revert a user could
likewise skip a commit, but needs to use 'git reset' (or in the case
of conflicts 'git reset --merge'), followed by 'git (cherry-pick |
revert) --continue' to skip the commit. This is more annoying and
sometimes confusing on the users' part. Add a `--skip` option to make

After a successful switch, if a merge, cherry-pick or revert is ongoing,
it is canceled. This behavior has been with us from the very early
beginning, soon after git-merge was created but never actually
documented [1]. It may be a good idea to be transparent and tell the
user if some operation is canceled.
I consider this a better way of telling the user than just adding a
sentence or two in git-checkout.txt, which will be mostly ignored
anyway.
PS. Originally I wanted to print more details like
warning: cancelling an in-progress merge from <SHA-1>
which may allow some level of undo if the user wants to. But that seems
a lot more work. Perhaps it can be improved later if people still want
that.

Introduce optname() that does the early half of original opterror() to
come up with the name of the option reported back to the user, and use
it to kill opterror(). The callers of opterror() now directly call
error() using the string returned by opterror() instead.
There are a few issues with opterror()
- it tries to assemble an English sentence from pieces. This is not
great for translators because we give them pieces instead of a full
sentence.
- It's a wrapper around error() and needs some hack to let the
compiler know it always returns -1.
- Since it takes a string instead of printf format, one call site has
to assemble the string manually before passing to it.
Using error() directly solves the second and third problems.
It kind helps the first problem as well because "%s does foo" does
give a translator a full sentence in a sense and let them reorder if
needed. But it has limitations, if the subject part has to change
based on the rest of the sentence, that language is screwed. This is
also why I try to avoid calling optname() when 'flags' is known in
advance.

The previous config handling relied on global variables, called
git_default_config() even when the key had already been handled by
git_sequencer_config() and did not initialize the diff configuration
variables. Improve this by: i) loading the default values for message
cleanup and gpg signing of commits into struct replay_opts;
ii) restructuring the code to return immediately once a key is
handled; and iii) calling git_diff_basic_config(). Note that
unfortunately it is not possible to return early if the key is handled
by git_gpg_config() as it does not indicate to the caller if the key
has been handled or not.
The sequencer should probably have been calling
git_diff_basic_config() before as it creates a patch when there are
conflicts. The shell version uses 'diff-tree' to create the patch so
calling git_diff_basic_config() should match that. Although 'git
commit' calls git_diff_ui_config() I don't think the output of
print_commit_summary() is affected by anything that is loaded by that
as print_commit_summary() always turns on rename detection so would
ignore the value in the user's configuration anyway. The other values
loaded by git_diff_ui_config() are about the formatting of patches so
are not relevant to print_commit_summary().

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).

When 'git log' is passed the --no-walk option, no revision walk takes
place, naturally. Perhaps somewhat surprisingly, however, the provided
revisions still get sorted by commit date. So e.g 'git log --no-walk
HEAD HEAD~1' and 'git log --no-walk HEAD~1 HEAD' give the same result
(unless the two revisions share the commit date, in which case they
will retain the order given on the command line). As the commit that
introduced --no-walk (8e64006 (Teach revision machinery about
--no-walk, 2007-07-24)) points out, the sorting is intentional, to
allow things like
git log --abbrev-commit --pretty=oneline --decorate --all --no-walk
to show all refs in order by commit date.
But there are also other cases where the sorting is not wanted, such
as
<command producing revisions in order> |
git log --oneline --no-walk --stdin
To accomodate both cases, leave the decision of whether or not to sort
up to the caller, by allowing --no-walk={sorted,unsorted}, defaulting
to 'sorted' for backward-compatibility reasons.

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

Advice messages are by definition meant for human end-users, and prime
candidates for i18n/l10n. They tend to also be more verbose to be helpful,
and need to be longer than just one line.
Although we do not have parameterized multi-line advice messages yet, once
we do, we cannot emit such a message like this:
advise(_("Please rename %s to something else"), gostak);
advise(_("so that we can avoid distimming %s unnecessarily."), doshes);
because some translations may need to have the replacement of 'gostak' on
the second line (or 'doshes' on the first line). Some languages may even
need to use three lines in order to fit the same message within a
reasonable width.
Instead, it has to be a single advise() construct, like this:
advise(_("Please rename %s to something else\n"
"so that we can avoid distimming %s unnecessarily."),
gostak, doshes);
Update the advise() function and its existing callers to
- take a format string that can be multi-line and translatable as a
whole;
- use the string and the parameters to form a localized message; and
- show each line in the result with the localization of the "hint: ".

an instruction sheet like this is now perfectly valid:
pick 35b0426
pick fbd5bbcbc2e
pick 7362160f
While at it, also fix a bug introduced by 5a5d80f4 (revert: Introduce
--continue to continue the operation, 2011-08-04) that failed to read
lines that are too long to fit on the commit-id-shaped buffer we
currently use; eliminate the need for the buffer altogether. In
addition to literal SHA-1 hexes, you can now safely use expressions
like the following in the instruction sheet:
featurebranch~4
rr/revert-cherry-pick-continue^2~12@{12 days ago}
[jc: simplify parsing]

Memory allocated to the fields of msg by get_message() isn't freed.
This is potentially a big leak, because fresh memory is allocated to
store the commit message for each commit. Fix this using
free_message().

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.

As v1.7.8-rc0~141^2~4 (2011-08-04) explains, git cherry-pick removes
the sequencer state just before applying the final patch. In the
single-pick case, that was a good thing, since --abort and --continue
work fine without access to such state and removing it provides a
signal that git should not complain about the need to clobber it ("a
cherry-pick or revert is already in progress") in sequences like the
following:
git cherry-pick foo
git read-tree -m -u HEAD; # forget that; let's try a different one
git cherry-pick bar
After the recent patch "allow single-pick in the middle of cherry-pick
sequence" we don't need that hack any more. In the new regime, a
traditional "git cherry-pick <commit>" command never looks at
.git/sequencer, so we do not need to cripple "git cherry-pick
<commit>..<commit>" for it any more.
So now you can run "git cherry-pick --abort" near the end of a
multi-pick sequence and it will abort the entire sequence, instead of
misbehaving and aborting just the final commit.

After messing up a difficult conflict resolution in the middle of a
cherry-pick sequence, it can be useful to be able to
git checkout HEAD . && git cherry-pick that-one-commit
to restart the conflict resolution. The current code however errors out
saying that another cherry-pick is already in progress.
