Subject: [PATCH v3 0/9] The final building block for a faster rebase -i
Date: Wed, 26 Apr 2017 13:59:07 +0200 (CEST) [thread overview]
Message-ID: <cover.1493207864.git.johannes.schindelin@gmx.de> (raw)
In-Reply-To: <cover.1493128210.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 v2:
- rearranged error_errno() calls to come before any subsequent free()
and close()
- now call close(fd) in case of error to avoid resource leaks
- removed unused `format` variable holding the value of
rebase.instructionFormat from rearrange_squash()
- modified rearrange_squash() to make it easier to reason about
subjects[i] taking custody of a strbuf's buffer (this should enable
Coverity to see that there is no resource leak here)
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
