I actually tried to reorder the patches and they seem to work OK as
expected. And I think it makes sense to order them the way I've
been suggesting, so I'll tentatively queue the result of reordering
on 'rr/rebase-checkout-reflog' and push it out as a part of 'pu'.
Please check to see if I introduced a new bug while doing so.
Regardless of the ordering, however, I suspect two patches that
change the message recorded in reflog in "rebase" need further
fixing.
For example, the one in "git reabse" does this:
GIT_REFLOG_ACTION="$GIT_REFLOG_ACTION: checkout $onto_name"
git checkout -q "$onto^0" || die "could not detach HEAD"
git update-ref ORIG_HEAD $orig_head
...
run_specific_rebase
But the specific rebase, e.g. git-rebase--interactive, does this:
case $head_name in
refs/*)
message="$GIT_REFLOG_ACTION: $head_name onto $onto" &&
git update-ref -m "$message" $head_name $newhead $orig_head &&
git symbolic-ref \
-m "$GIT_REFLOG_ACTION: returning to $head_name" \
HEAD $head_name
;;
esac && {
I think the message you added to "git reabse" is only meant for that
specific "checkout $onto", but it is set globally. Wouldn't it
affect later use, which expected it to be "rebase" and nothing else?
Perhaps something like this on top of the entire series may be
sufficient (which will be queued as "SQUASH???" at the tip).
Hint for anybody (not limited to Ram):
There also are other 'git checkout' invocations in git-rebase\*.sh
that are not yet covered by these "nicer reflog message" patches,
which may want to be fixed up before these two icing-on-cake patches
become ready to be merged; see output of
git grep -C2 'git checkout' -- git-rebase\*.sh
Thanks.
