This patch series reimplements the expensive pre- and post-processing of the todo script in C. And it concludes the work I did to accelerate rebase -i. Changes since v1: - rebased to the current `master` (which advanced quite a bit since v1 was sent to the list on September 2nd, 2016) - downcased error messages - marked error messages for translation - moved an "else" onto the same line as the preceding closing brace - described the priorities of `fixup! <something>` in the man page, as suggested by Philip Oakley Johannes Schindelin (9): rebase -i: generate the script via rebase--helper rebase -i: remove useless indentation rebase -i: do not invent onelines when expanding/collapsing SHA-1s rebase -i: also expand/collapse the SHA-1s via the rebase--helper t3404: relax rebase.missingCommitsCheck tests rebase -i: check for missing commits in the rebase--helper rebase -i: skip unnecessary picks using the rebase--helper t3415: test fixup with wrapped oneline rebase -i: rearrange fixup/squash lines using the rebase--helper Documentation/git-rebase.txt | 16 +- builtin/rebase--helper.c | 29 ++- git-rebase--interactive.sh | 362 ++++------------------------- sequencer.c | 515 ++++++++++++++++++++++++++++++++++++++++++ sequencer.h | 8 + t/t3404-rebase-interactive.sh | 22 +- t/t3415-rebase-autosquash.sh | 16 +- 7 files changed, 625 insertions(+), 343 deletions(-) base-commit: e2cb6ab84c94f147f1259260961513b40c36108a Based-On: rebase--helper at https://github.com/dscho/git Fetch-Base-Via: git fetch https://github.com/dscho/git rebase--helper Published-As: https://github.com/dscho/git/releases/tag/rebase-i-extra-v2 Fetch-It-Via: git fetch https://github.com/dscho/git rebase-i-extra-v2 Interdiff vs v1: diff --git a/Documentation/git-rebase.txt b/Documentation/git-rebase.txt index 67d48e68831..da79fbda5b3 100644 --- a/Documentation/git-rebase.txt +++ b/Documentation/git-rebase.txt @@ -425,13 +425,15 @@ without an explicit `--interactive`. --autosquash:: --no-autosquash:: When the commit log message begins with "squash! ..."
