I completely agree.

I also thought the sorting was just a bug. From what I understand by
looking how the code has evolved, the sorting in the no-walk case was
not intentional, but more of a consequence of the implementation. That
patch you suggested was my first attempt and led me to find the broken
cherry-pick test cases that I then fixed in patch 2/4. But, it clearly
would break the test case in t4202 called 'git log --no-walk <commits>
sorts by commit time'. So I started digging from there and found e.g.
For convenience, I have pasted the commit message of the commit
mentioned in that thread at the end of this email. So we would be
breaking at least Johannes's use case if we changed it. I would think
almost everyone who doesn't already know would expect "git rev-list A
B" to list them in that order, so is a migration desired? Or just
change the default for --no-walk from "sorted" to "unsorted" in git
By the way, git-log's documentation says "By default, the commits are
shown in reverse chronological order.", which to some degree is in
support of the current behavior.

Teach revision machinery about --no-walk
The flag "no_walk" is present in struct rev_info since a long time, but
so far has been in use exclusively by "git show".
With this flag, you can see all your refs, ordered by date of the last
$ git log --abbrev-commit --pretty=oneline --decorate --all --no-walk
which is extremely helpful if you have to juggle with a lot topic
branches, and do not remember in which one you introduced that uber
debug option, or simply want to get an overview what is cooking.
(Note that the "git log" invocation above does not output the same as
$ git show --abbrev-commit --pretty=oneline --decorate --all --quiet
since "git show" keeps the alphabetic order that "--all" returns the
refs in, even if the option "--date-order" was passed.)
For good measure, this also adds the "--do-walk" option which overrides
