Hello,
since Git 2.16.1, I've noticed a bad behaviour of git rebase -i -p. It
screws up merge commits created with --log (or config merge.log = true)
in my history. A good merge commit with message like:
Merge branch 'test'
* test:
c
b
is changed after rebase (without touching that commit in any way) into:
Merge branch 'test' a git-rebase-p-test.sh test: c b
It seems, like the commit message is interpreted somehow - the '*'
character is expanded to the list of files in the current directory and
the original spacing is removed. This happens during my regular work.
Here is a code that seems to be reproducing this behaviour well:
git init
touch a
git add a
git commit -m a
git checkout -b test
# a new branch made to merge back to master later
touch b
git add b
git commit -m b
touch c
git add c
git commit -m c
git checkout master
git merge --no-edit --log test
git log -1
# everything looks good at this point
export GIT_SEQUENCE_EDITOR='sed "1s/pick/reword/" -i'
# we are rewording only the first commit...
export EDITOR='sed "s/b/x/" -i'
# ...and changing its message from "b" to "x"
git rebase -i HEAD^1 -p
git log -1
# here, you can see the bad merge commit message
Regards
Jan
