It does not run for `git revert`. This does look like an oversight to me, but you'll have to bear with me since I am relatively unfamiliar with the sequencer code. Ultimately `git revert` calls do_pick_commit() which either calls do_commit() or run_git_commit(). A couple of curiosities there: - do_commit() does fall back to run_git_commit() if it has the VERIFY_MSG bit set in `flags`. - run_git_commit() passes `-n` only when VERIFY_MSG *isn't* set, so the VERIFY_MSG bit does imply that the pre-commit hook would be run there. - when do_pick_commit() does have to fall back to run_git_commit(), it sets the VERIFY_MSG bit in flags. But we never end up calling run_git_commit() (except in the case of errors) because do_pick_commit() special-cases `command == TODO_REVERT` (which is the case for `git revert`) and calls `do_commit()`. But it gets weirder: do_commit() calls run_git_commit() itself, but before the caller in do_pick_commit() has had a chance to add VERIFY_MSG to the flags. So I suspect that this is an oversight, but perhaps somebody more familiar with this code could confirm my thinking. Thanks, Taylor ^ permalink raw reply [flat|nested] 10+ messages in thread

IIRC, the "--continue" option that creates a commit came much later for lazy folks; the norm was to conclude your conflict resolution with "git commit" so that the HEAD and the index and the working tree matches before running "--continue". Wouldn't that work in this case? That is $ git <some sequencing command> A..B ... ... stops with conflict $ edit $ git add ... $ git commit --no-verify $ git <that sequencing command> --continue ^ permalink raw reply [flat|nested] 10+ messages in thread

It does not run for `git revert`. The general rule for cherry-pick, revert and rebase is that if the commit message is edited then the commit is made with --verify and if the commit message is not being edited then the commit is made with --no-verify. I think the reasoning for this is that if the user has altered the commit message or contents and they have a pre-commit hook set then it is reasonable to check the new commit is acceptable to the hook. There are some exceptions to this which are oversights (for example I think we always pass --no-verify when committing a conflict resolution with 'git rebase --continue' even though the editor opens when committing in that case - I should try and fix that) For 'git revert --continue' the commit is made when sequencer_continue() calls continue_single_pick() which looks like static int continue_single_pick(struct repository *r, struct replay_opts *opts) { struct strvec argv = STRVEC_INIT; int ret; if (!refs_ref_exists(get_main_ref_store(r), "CHERRY_PICK_HEAD") && !refs_ref_exists(get_main_ref_store(r), "REVERT_HEAD")) return error(_("no cherry-pick or revert in progress")); strvec_push(&argv, "commit"); /* * continue_single_pick() handles the case of recovering from a * conflict. should_edit() doesn't handle that case; for a conflict, * we want to edit if the user asked for it, or if they didn't specify * and stdin is a tty. */ if (!opts->edit || (opts->edit < 0 && !isatty(0))) /* * Include --cleanup=strip as well because we don't want the * "# Conflicts:" messages. */ strvec_pushl(&argv, "--no-edit", "--cleanup=strip", NULL); ret = run_command_v_opt(argv.v, RUN_GIT_CMD); strvec_clear(&argv); return ret; } It runs git commit directly and never passes --no-verify. I wouldn't be opposed to someone adding support for --no-verify (and --no-edit) to "cherry-pick/revert/rebase --continue" on the understanding that it only applied when committing the conflict resolution. There is a possible confusion for users though who might expect that the options passed with '--continue' applied to all the commits made by the command. > This does look like an oversight to me, but you'll have to bear with me > since I am relatively unfamiliar with the sequencer code. > > Ultimately `git revert` calls do_pick_commit() This is what happens when we are picking commits, the commit made with '--continue' uses a different code path > which either calls > do_commit() or run_git_commit().

Calling run_git_commit() there is not a fallback it, that call is used to reword commits once they have been picked (see 450efe2d53 ("rebase -i: always update HEAD before rewording", 2019-08-19) for the reasoning behind this) . Because the message is being edited there is no point in going through do_commit(). > But we never end up calling run_git_commit() (except in the case of > errors) because do_pick_commit() special-cases `command == TODO_REVERT` > (which is the case for `git revert`) and calls `do_commit()`. > > But it gets weirder: do_commit() calls run_git_commit() itself, but > before the caller in do_pick_commit() has had a chance to add VERIFY_MSG > to the flags. do_commit() does not change the flags that it is called with - callers that want VERIFY_MSG will set that before they call do_commit(). do_commit() is there to commit simple picks without forking 'git commit' > So I suspect that this is an oversight, but perhaps somebody more > familiar with this code could confirm my thinking. I hope the above helps - basically the idea is "if the commit has been edited use VERIFY_MSG" and --continue unhelpfully uses a completely different code-path to the main commit picking/reverting loop.

Yeah, that feels like we are just trying to confuse the user ;).
