Subject: [PATCH v2 0/9] The final building block for a faster rebase -i
Date: Tue, 25 Apr 2017 15:51:46 +0200 (CEST) [thread overview]
Message-ID: <cover.1493128210.git.johannes.schindelin@gmx.de> (raw)
In-Reply-To: <cover.1472833365.git.johannes.schindelin@gmx.de>
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
