我可以在 reflog 中添加一行吗？

Question

由于一个拙劣的 git commit --fixup，我正处于 rebase 地狱之中。我想我已经确定了来源，而且我的处境比开始时更好。但是，如果我查看 git reflog，这一系列 'rebase -i' 行看起来就像我之前的拙劣尝试。

我可以将自己的行添加到 reflog 吗？说一些看起来像的东西：

$ git reflog mark '== we are not worse off than we started here =='
$ git reflog -3
cb6536f HEAD@{0}: mark: == we are not worse off than we started here ==
cb6536f HEAD@{1}: rebase -i (finish): fixup! foo: baz the widgets
9db07de HEAD@{1}: rebase -i (pick): fixup! baz: implement widget bazzing

您可以随时使用 git 用于添加新的 reflog 条目的相同命令添加新的 reflog 条目，即 git update-ref。这是一个 "plumbing"（面向脚本的）命令，因此对用户来说不是很友好，您可能想要添加自己的小包装脚本或别名。

示例：

git update-ref -m 'mark: whatever' HEAD HEAD
git update-ref -m 'mark: another thing' refs/heads/branch branch
git update-ref -m 'mark: third thing' refs/heads/branch refs/heads/branch
hash=$(git rev-parse refs/heads/branch) && \
   git update-ref -m 'mark: 4' refs/heads/branch $hash

请注意 <ref>（第一个非选项参数）必须完整拼写。 <newvalue> 可以是解析为有效 SHA-1 的任何内容，这就是三个示例的中间命令可以工作的原因，但为了安全起见，最好使用第三种形式（重复 <ref> 准确）或使用实际的 SHA-1 哈希（第四种形式），让 git rev-parse 验证这实际上是一个有效的分支名称。

（使用 HEAD 时可以跳过验证，因为如果 HEAD 不是有效名称，git 根本无法运行。）

如本文所述2020 thread：

There is the option core.logAllRefUpdates, which has the value "always" in more modern versions of Git.
The documentation says:

If the option is set to always, then a missing reflog is automatically created for any ref under refs/.

Now, that assumes that you want reflogs for all your refs, but there's really not much downside to having a reflog and not using it.

杰夫·金斯补充道：

The current rule is actually to append to any reflog that already exists, or to consult core.logAllRefUpdates when deciding whether to create one that doesn't exist. So I think setting a one-shot config variable like:
git -c core.logAllRefUpdates=always update-ref refs/foo/bar ...
would create the reflog, and then any subsequent updates (even without that config set) would append to it.

You can also do this:
mkdir -p .git/logs/refs/foo/
touch .git/logs/refs/foo/bar
git update-ref refs/foo/bar ...
but I wouldn't recommend it.
When we eventually move to supporting other ref backend formats, they won't necessarily store the logs in the same way.

我可以在 reflog 中添加一行吗？

Can I add a line to the reflog?
