2019-08-19sequencer: simplify root commit creationPhillip Wood
Adapt try_to_commit() to create a new root commit rather than special casing this in run_git_commit(). This significantly reduces the amount of special case code for creating the root commit and reduces the number of commit code paths we have to worry about.

2019-08-19rebase -i: check for updated todo after squash and rewordPhillip Wood
While a rebase is stopped for the user to edit a commit message it can be convenient for them to also edit the todo list. The scripted version of rebase supported this but the C version does not. We already check to see if the todo list has been updated by an exec command so extend this to rewords and squashes. It only costs a single stat call to do this so it should not affect the speed of the rebase (especially as it has just stopped for the user to edit a message) Note that for squashes the editor may be opened on a different pick to the squash itself as we edit the message at the end of a chain fixups and squashes.

2019-08-19rebase -i: always update HEAD before rewordingPhillip Wood
If the user runs git log while rewording a commit it is confusing if sometimes we're amending the commit that's being reworded and at other times we're creating a new commit depending on whether we could fast-forward or not[1]. Fix this inconsistency by always committing the picked commit and then running 'git commit --amend' to do the reword. The first commit is performed by the sequencer without forking git commit and does not impact on the speed of rebase. In a test rewording 100 commits with GIT_EDITOR=true GIT_SEQUENCE_EDITOR='sed -i s/pick/reword/' \ ../bin-wrappers/git rebase -i --root and taking the best of three runs the current master took 957ms and with this patch it took 961ms. This change fixes rewording the new root commit when rearranging commits with --root. Note that the new code no longer updates CHERRY_PICK_HEAD after creating a root commit - I'm not sure why the old code was that creating that ref after a successful commit, everywhere else it is removed after a successful commit.

2019-08-19merge-recursive: don't force external callers to do our loggingElijah Newren
Alternatively, you can view this as "make the merge functions behave more similarly." merge-recursive has three different entry points: merge_trees(), merge_recursive(), and merge_recursive_generic(). Two of these would call diff_warn_rename_limit(), but merge_trees() didn't. This lead to callers of merge_trees() needing to manually call diff_warn_rename_limit() themselves. Move this to the new merge_finalize() function to make sure that all three entry points run this function. Note that there are two external callers of merge_trees(), one in sequencer.c and one in builtin/checkout.c. The one in sequencer.c is cleaned up by this patch and just transfers where the call to diff_warn_rename_limit() is made; the one in builtin/checkout.c is for switching to a different commit and in the very rare case where the warning might be triggered, it would probably be helpful to include (e.g. if someone is modifying a file that has been renamed in moving to the other commit, but there are so many renames between the commits that the limit kicks in and none are detected, it may help to have an explanation about why they got a delete/modify conflict instead of a proper content merge in a renamed file).

2019-07-02cherry-pick/revert: add --skip optionRohit Ashiwal
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 skipping commits easier for the user and to make the commands more consistent. In the next commit, we will change the advice messages hence finishing the process of teaching revert and cherry-pick "how to skip commits".

2019-06-27rebase: fix garbled progress display with '-x'SZEDER Gábor
When running a command with the 'exec' instruction during an interactive rebase session, or for a range of commits using 'git rebase -x', the output can be a bit garbled when the name of the command is short enough: $ git rebase -x true HEAD~5 Executing: true Executing: true Executing: true Executing: true Executing: true) Successfully rebased and updated refs/heads/master. Note the ')' at the end of the last line. It gets more garbled as the range of commits increases: $ git rebase -x true HEAD~50 Executing: true) [ repeated 3 more times ] Executing: true0) [ repeated 44 more times ] Executing: true00) Successfully rebased and updated refs/heads/master. Those extra numbers and ')' are remnants of the previously displayed "Rebasing (N/M)" progress lines that are usually completely overwritten by the "Executing: <cmd>" lines, unless 'cmd' is short and the "N/M" part is long. Make sure that the previously displayed "Rebasing (N/M)" line is cleared by using the term_clear_line() helper function added in the previous patch. Do so only when not being '--verbose', because in that case these "Rebasing (N/M)" lines are not printed as progress (i.e. as lines with '\r' at the end), but as "regular" output (with '\n' at the end). A couple of other rebase commands print similar messages, e.g. "Stopped at <abbrev-oid>... <subject>" for the 'edit' or 'break' commands, or the "Successfully rebased and updated <full-ref>." at the very end. These are so long that they practically always overwrite that "Rebasing (N/M)" progress line, but let's be prudent, and clear the last line before printing these, too. In 't3420-rebase-autostash.sh' two helper functions prepare the expected output of four tests that check the full output of 'git rebase' and thus are affected by this change, so adjust their expectations to account for the new line clearing. Note that this patch doesn't completely eliminate the possibility of similar garbled outputs, e.g. some error messages from rebase or the "Auto-merging <file>" message from within the depths of the merge machinery might not be long enough to completely cover the last "Rebasing (N/M)" line. This patch doesn't do anything about them, because dealing with them individually would result in way too much churn, while having a catch-all term_clear_line() call in the common code path of pick_commits() would hide the "Rebasing (N/M)" line way too soon, and it would either flicker or be invisible.

2019-06-27status: do not report errors in sequencer/todoPhillip Wood
commit 4a72486de9 ("fix cherry-pick/revert status after commit", 2019-04-16) used parse_insn_line() to parse the first line of the todo list to check if it was a pick or revert. However if the todo list is left over from an old cherry-pick or revert and references a commit that no longer exists then parse_insn_line() prints an error message which is confusing for users [1]. Instead parse just the command name so that the user is alerted to the presence of stale sequencer state by status reporting that a cherry-pick or revert is in progress. Note that we should not be leaving stale sequencer state lying around (or at least not as often) after commit b07d9bfd17 ("commit/reset: try to clean up sequencer state", 2019-04-16). However the user may still have stale state that predates that commit. Also avoid printing an error message if for some reason the user has a file called `sequencer` in $GIT_DIR.

2019-06-27sequencer: factor out todo command name parsingPhillip Wood
Factor out the code that parses the name of the command at the start of each line in the todo file into its own function so that it can be used in the next commit. As I don't want to burden other callers with having to pass in a pointer to the end of the line the test for an abbreviated command is changed. This change should not affect the behavior. Instead of testing `eol == bol + 1` the new code checks for the end of the line by testing for '\n', '\r' or '\0' following the abbreviated name. To avoid reading past the end of an empty string it also checks that there is actually a single character abbreviation before testing if it matches. This prevents it from matching '\0' as the abbreviated name and then trying to read another character.

2019-04-19sequencer: always discard index after checkoutPhillip Wood
As the checkout runs in a separate process our index will be out of date so it should be discarded. The existing callers are not doing this consistently so do it here to avoid the callers having to worry about it. This fixes some test failures that happen if do_interactive_rebase() is called without forking rebase--interactive which we will implement shortly. Running git rebase -i master topic starting on master created empty todo lists because all the commits in topic were marked as cherry-picks. After topic was checked out in prepare_branch_to_be_rebased() the working tree contained the contents from topic but the index contained master and the cache entries were still valid. This meant that diff_populate_filespec() which loads the blobs when calculating patch-id's ended up reading the contents for master from the working tree which actually contained topic.

2019-04-19cherry-pick/revert: add scissors line on merge conflictDenton Liu
Fix a bug where the scissors line is placed after the Conflicts: section, in the case where a merge conflict occurs and commit.cleanup = scissors. Helped-by: Phillip Wood <phillip.wood@dunelm.org.uk> Signed-off-by: Denton Liu <liu.denton@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2019-04-18sequencer: fix cleanup with --signoff and -xPhillip Wood
Before commit 356ee4659b ("sequencer: try to commit without forking 'git commit'", 2017-11-24) when --signoff or -x were given on the command line the commit message was cleaned up with --cleanup=space or commit.cleanup if it was set. Unfortunately this behavior was lost when I implemented committing without forking. Fix this and add some tests to catch future regressions.

2019-04-17fix cherry-pick/revert status after commitPhillip Wood
If the user commits a conflict resolution using `git commit` in the middle of a sequence of cherry-picks/reverts then `git status` missed the fact that a cherry-pick/revert is still in progress.

2019-04-17commit/reset: try to clean up sequencer statePhillip Wood
When cherry-picking or reverting a sequence of commits and if the final pick/revert has conflicts and the user uses `git commit` to commit the conflict resolution and does not run `git cherry-pick --continue` then the sequencer state is left behind. This can cause problems later. In my case I cherry-picked a sequence of commits the last one of which I committed with `git commit` after resolving some conflicts, then a while later, on a different branch I aborted a revert which rewound my HEAD to the end of the cherry-pick sequence on the previous branch. Avoid this potential problem by removing the sequencer state if we're committing or resetting the final pick in a sequence.
