Does "git cherry-pick" even trigger pre-commit hook in the first
place? In my quick tests, it does not seem to.
$ git init test
$ cd test
$ printf "%s\n" '#!/bin/sh' 'echo >&2 no' 'exit 1' >.git/hooks/pre-commit
$ chmod +x .git/hooks/pre-commit
$ git commit --allow-empty -m initial
no
Up to this point, I set up a pre-commit that stops me
unconditionally and made sure it is working.
$ git commit --no-verify --allow-empty -m initial
[master (root-commit) 5d967c2] initial
$ I=$(git rev-parse HEAD)
$ echo "foo" >file
$ git add file
$ git commit --no-verify -m 'add file'
[master 93a33c4] add file
1 file changed, 1 insertion(+)
create mode 100644 file
Then I built two commits
$ git checkout --detach $I
HEAD is now at 5d967c2 initial
And rewound to the initial commit so that the second one can be
cherry-picked on top of it.
$ git cherry-pick master
[detached HEAD 699c604] add file
Date: Mon Mar 14 15:58:38 2022 -0700
1 file changed, 1 insertion(+)
create mode 100644 file
And that is understandable, as "cherry-pick" is more about replaying
what was committed in the past, with bugs and crufts preserved, than
committing a new-and-improved version out of an existing commit.
Perhaps in a case where a conflict stops the command there is
something? Let's see. Continuing from the above transcript:
$ git cherry-pick master
HEAD detached from 5d967c2
You are currently cherry-picking commit 93a33c4.
(all conflicts fixed: run "git cherry-pick --continue")
(use "git cherry-pick --skip" to skip this patch)
(use "git cherry-pick --abort" to cancel the cherry-pick operation)
nothing to commit, working tree clean
The previous cherry-pick is now empty, possibly due to conflict resolution.
If you wish to commit it anyway, use:
git commit --allow-empty
Otherwise, please use 'git cherry-pick --skip'
$ edit file
$ git commit --allow-empty -a
no
Of course, "git commit" to conclude a conflicted cherry-pick,
possibly with intervening conflict resolutin by editing working tree
files, would by default trigger pre-commit hook, and it of course
takes --no-verify as expected.
$ git commit --allow-empty -a --no-verify --no-edit
[detached HEAD 5858d22] add file
Date: Mon Mar 14 15:58:38 2022 -0700
Ahh, I think the user is fooled by a bad advice in the message.
(all conflicts fixed: run "git cherry-pick --continue") is wrong and
misleading advice added by those who did not think things through.
After fixing all conflicts, run "git commit" to record it and then
you run "git cherry-pick --continue" if there are more steps to
cherry-pick (i.e. "git cherry-pick A..B"). "git commit" takes not
just "--no-verify" but other options like "--reset-author" to let
you take over authorship if the conflict resolution (actually,
adjusting the original commit to the different context it is being
cherry-picked to) is so involved that a change of authorship is
warranted. "cherry-pick --continue" does not have all the necessary
flexibility and conceptually it is a separte operation (i.e. "please
continue the stopped sequence" is what it means) from concluding the
current step in the sequence.
