git - 没有强制推送的 Git 镜像

Question

是否有可能以某种方式设置一个像往常一样工作的 git 存储库 --mirror 用于拉入它，但在从它推送到另一个 repo 时不强制？

Answer 1

您可以添加 --no-force 来禁用强制行为，如下所示：

git push --mirror --no-force

这将禁用非快进更新（使用 git 1.8.0.2 测试）。

Answer 2

I'd like to do a git push --mirror that will fail if a non-fast forward update is required.

A git push --mirror should fail if the upstream repo has its config set to receive.denyNonFastForwards true:

git config man page:

receive.denyNonFastForwards

If set to true, git-receive-pack will deny a ref update which is not a fast-forward.
Use this to prevent such an update via a push, even if that push is forced.
This configuration variable is set when initializing a shared repository.

That means you wouldn"t have to "reproduce what --mirror" does: you could simply use it, and still have that push fail if any non-fastforward merge is involved.

Answer 3

有没有办法重现 --mirror 对其他选项的作用？

镜像的某些功能可以通过多次推送来执行：

git push <remote> --all  # push all branches
git push <remote> --tags # push all tags
git push <remote> refs/remotes/* #push the remote refs
