Subject: [PATCH v5 0/2] rebase -i: extend rebase.missingCommitsCheck
Date: Sat, 25 Jan 2020 18:54:34 +0100 [thread overview]
Message-ID: <20200125175436.29786-1-alban.gruin@gmail.com> (raw)
In-Reply-To: <20200111173917.15690-1-alban.gruin@gmail.com>
To prevent mistakes when editing a branch, rebase features a knob,
rebase.missingCommitsCheck, to warn the user if a commit was dropped.
Unfortunately, this check is only effective for the initial edit, which
means that if you edit the todo list at a later point of the rebase and
drop a commit, no warnings or errors would be issued.
This adds the ability to check if commits were dropped when editing the
todo list with `--edit-todo', and when resuming a rebase.
The first patch moves moves check_todo_list_from_file() and
`edit_todo_list_advice' from sequencer.c to rebase-interactive.c so the
latter can be used by edit_todo_list() and todo_list_check(). The
second patch adds the check to `--edit-todo' and `--continue' and tests.
This is based on 393adf7a6f ("sequencer: directly call pick_commits()
from complete_action()", 2019-11-24).
The tip of this series is tagged as "edit-todo-drop-v5" at
https://github.com/agrn/git.
Changes since v4:
- Added a test to check that no errors are raised when editing the todo
list after pausing the rebase; it was provided by Phillip Wood.
- Fixed the issue pointed out by this test by creating a backup of the
todo list even if the edited list is incorrect. This step was moved
before the user edits the list, so the backup can be created with
copy_file() instead of todo_list_write_to_file().
- In edit_todo_list(), `incorrect' is set to 0 by default. This only
concerns the initial edit case; instead of opening and parsing the
backup, we use directly `old_todo' as a reference.
- Don't check if the "dropped" file flag exists at the initial edit.
