Subject: [RFC PATCH 1/9] t3404: demonstrate that --edit-todo does not check for dropped commits
Date: Wed, 17 Jul 2019 16:39:10 +0200	[thread overview]
Message-ID: <20190717143918.7406-2-alban.gruin@gmail.com> (raw)
In-Reply-To: <20190717143918.7406-1-alban.gruin@gmail.com>

When set to "warn" or "error", `rebase.missingCommitCheck' would make
rebase -i warn if the user removed commits from the todo list to prevent
mistakes.  Unfortunately, rebase --edit-todo and rebase --continue don't
take it into account.

This adds three tests to t3404 to demonstrate this.  The first one is
not broken, as when `rebase.missingCommitsCheck' is not set, nothing in
particular must be done towards dropped commits.  The two others are
broken, demonstrating the problem.
