"git cherry-pick/revert" with or without "--[no-]edit" did not spawn the editor as expected (e.g. "revert --no-edit" after a conflict still asked to edit the message), which has been corrected. * en/sequencer-edit-upon-conflict-fix: sequencer: fix edit handling for cherry-pick and revert messages
2021-03-31sequencer: fix edit handling for cherry-pick and revert messagesLibravatar Elijah Newren1-11/+41
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.

2021-03-20merge-ort: write $GIT_DIR/AUTO_MERGE whenever we hit a conflictLibravatar Elijah Newren1-0/+5
There are a variety of questions users might ask while resolving conflicts: * What changes have been made since the previous (first) parent? * What changes are staged? * What is still unstaged? (or what is still conflicted?) * What changes did I make to resolve conflicts so far? The first three of these have simple answers: * git diff HEAD * git diff --cached * git diff There was no way to answer the final question previously. Adding one is trivial in merge-ort, since it works by creating a tree representing what should be written to the working copy complete with conflict markers. Simply write that tree to .git/AUTO_MERGE, allowing users to answer the fourth question with * git diff AUTO_MERGE I avoided using a name like "MERGE_AUTO", because that would be merge-specific (much like MERGE_HEAD, REBASE_HEAD, REVERT_HEAD, CHERRY_PICK_HEAD) and I wanted a name that didn't change depending on which type of operation the merge was part of. Ensure that paths which clean out other temporary operation-specific files (e.g. CHERRY_PICK_HEAD, MERGE_MSG, rebase-merge/ state directory) also clean out this AUTO_MERGE file.

2021-01-28rebase -i: do leave commit message intact in fixup! chainsLibravatar Johannes Schindelin1-1/+12
In 6e98de72c03 (sequencer (rebase -i): add support for the 'fixup' and 'squash' commands, 2017-01-02), this developer introduced a change of behavior by mistake: when encountering a `fixup!` commit (or multiple `fixup!` commits) without any `squash!` commit thrown in, the final `git commit` was invoked with `--cleanup=strip`. Prior to that commit, the commit command had been called without that `--cleanup` option. Since we explicitly read the original commit message from a file in that case, there is really no sense in forcing that clean-up. We actually need to actively suppress that clean-up lest a configured `commit.cleanup` may interfere with what we want to do: leave the commit message unchanged.

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.

2020-09-30sequencer: handle ignore_footer when parsing trailersLibravatar Jeff King1-0/+9
The append_signoff() function takes an "ignore_footer" argument, which specifies a number of bytes at the end of the message buffer which should not be considered (they cannot contain trailers, and the trailer is spliced in before them). But to find the existing trailers, it calls into has_conforming_trailer(). That function takes an ignore_footer parameter, but since 967dfd4d56 (sequencer: use trailer's trailer layout, 2016-11-02) the parameter is completely ignored. The trailer interface we're using takes a single string, with no option to tell it to use part of the string. However, since we have a mutable strbuf, we can work around this by simply overwriting (and later restoring) the boundary with a NUL. I'm not sure if this can actually trigger a bug in practice. It's easy to get a non-zero ignore_footer by doing something like this: git commit -F - --cleanup=verbatim <<-EOF subject body Signed-off-by: me # this looks like a comment, but is actually in the # message! That makes the earlier s-o-b fake. EOF git commit --amend -s There git-commit calls ignore_non_trailer() to count up the "#" cruft, which becomes the ignore_footer header. But it works even without this patch! That's because the trailer code _also_ calls ignore_non_trailer() and skips the cruft, too. So it happens to work because the only callers with a non-zero ignore_footer are using the exact same function that the trailer parser uses internally. And that seems true for all of the current callers, but there's nothing guaranteeing it. We're better off only feeding the correct buffer to the trailer code in the first place.

2020-09-30sequencer: drop repository argument from run_git_commit()Libravatar Jeff King1-6/+5
When we switched to using an external git-commit call in b0a3186140 (sequencer: simplify root commit creation, 2019-08-19), this function didn't need to care about the repository object any more. Arguably we could be passing along the repository path to the external git-commit by using "--git-dir=r->path" here. But for the most part the sequencer code relies on sub-process finding the same repository we're already in (using the same environment variables or discovery process we did). But we don't have a convenient interface for doing so, and there's no indication that we need to. Let's just drop the unused parameter for now.

2020-09-25sequencer: stop abbreviating stopped-sha fileLibravatar Junio C Hamano1-5/+6
The object name written to this file is not exposed to end-users and the only reader of this file immediately expands it back to a full object name. Stop abbreviating while writing, and expect a full object name while reading, which simplifies the code a bit. Signed-off-by: Junio C Hamano <gitster@pobox.com>
