Subject: [PATCH v4 03/19] rebase (interactive-backend): make --keep-empty the default
Date: Thu, 16 Jan 2020 06:14:17 +0000
Message-ID: <179f82ab83e669ca8da7ce999607cae584bc18df.1579155273.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.679.v4.git.git.1579155273.gitgitgadget@gmail.com>

From: Elijah Newren <newren@gmail.com>

Different rebase backends have different treatment for commits which
start empty (i.e. have no changes relative to their parent), and the
--keep-empty option was added at some point to allow adjusting behavior
for the interactive backend.  The handling of commits which start empty
is actually quite similar to commit b00bf1c9a8dd (git-rebase: make
--allow-empty-message the default, 2018-06-27), which pointed out that
the behavior for various backends is often more happenstance than
design.  The specific change made in that commit is actually quite
relevant as well and much of the logic there directly applies here.

It makes a lot of sense in 'git commit' to error out on the creation of
empty commits, unless an override flag is provided.  However, once
someone determines that there is a rare case that merits using the
manual override to create such a commit, it is somewhere between
annoying and harmful to have to take extra steps to keep such
intentional commits around.  Granted, empty commits are quite rare,
which is why handling of them doesn't get considered much and folks tend
to defer to existing (accidental) behavior and assume there was a reason
for it, leading them to just add flags (--keep-empty in this case) that
allow them to override the bad defaults.  Fix the interactive backend so
that --keep-empty is the default, much like we did with
--allow-empty-message.  The am backend should also be fixed to have
--keep-empty semantics for commits that start empty, but that is not
included in this patch other than a testcase documenting the failure.

Note that there was one test in t3421 which appears to have been written
expecting --keep-empty to not be the default as correct behavior.  This
test was introduced in commit 00b8be5a4d38 ("add tests for rebasing of
empty commits", 2013-06-06), which was part of a series focusing on
rebase topology and which had an interesting original cover letter at
https://lore.kernel.org/git/1347949878-12578-1-git-send-email-martinvonz@gmail.com/
which noted
    Your input especially appreciated on whether you agree with the
    intent of the test cases.
and then went into a long example about how one of the many tests added
had several questions about whether it was correct.  As such, I believe
most the tests in that series were about testing rebase topology with as
many different flags as possible and were not trying to state in general
how those flags should behave otherwise.
