Subject: [PATCH 0/3] Re-fix rebase -i with SHA-1 collisions
Date: Thu, 16 Jan 2020 21:18:23 +0000 [thread overview]
Message-ID: <pull.529.git.1579209506.gitgitgadget@gmail.com> (raw)
Triggered by one of brian's SHA-256 patch series, I looked at the reason why
the SHA-1 collision test case passed when it shouldn't. Turns out that the
regression test was not quite thorough enough, and the interactive rebase
did regress recently.
While in the area, I realized that the same bug exists in the code backing
the rebase.missingCommitsCheck feature: the backed-up todo list uses
shortened commit IDs that may very well become ambiguous during the rebase.
For good measure, this patch series fixes that, too.
Finally, I saw that git rebase --edit-todo reported the line in an awkward,
maybe even incorrect, way when there was an ambiguous commit ID, and I also
fixed that.
To make sure that the code can be easily adapted to SHA-256 after these
patches, I actually already made those adjustments on top and offered them
up at https://github.com/bk2204/git/pull/1.

parse_insn_line(): improve error message when parsing failed
