撤消'git push' [英] Undoing a 'git push'

问题描述

这就是我在我的应该是稳定的分支上所做的...

$ b

 ％git rebase master 
首先，倒带头重播你的作品... 
快速转发alpha-0.3.0来掌握。 
％git status 
＃在分支上alpha-0.3.0 
＃你的分支在53次提交之前超过'origin / alpha-0.3.0'。 
＃
无需提交（工作目录清理）
％git push 
获取远程主管... 
 refs / 
 refs / heads / 
 refs / tags / 
 refs / remotes / 
'refs / heads / master'：最新
更新'refs / heads / alpha-0.3.0'
从cc4b63bebb6e6dd04407f8788938244b78c50285 
到83c9191dea88d146400853af5eb7555f252001b0 
完成$ b $ refs / heads / unstable'：最新
更新远程服务器信息
  

我后来意识到这是一个错误。我想撤销整个过程，并将alpha-0.3.0分支恢复到原来的状态。

我应该怎么做？

解决方案

您需要确保此存储库的其他用户不会获取不正确的更改或尝试在您想要删除的提交之上构建因为你即将倒回历史。

然后你需要'强制'推送旧的参考。 $ p> git push -f origin last_known_good_commit：branch_name


或者你的情况

  git push -f原点cc4b63bebb6：alpha-0.3.0 
  

您可能在远程存储库上设置了 receive.denyNonFastForwards 。如果是这种情况，那么你会得到一个错误，其中包括短语 [远程拒绝] 。

这种情况下，你将不得不删除并重新创建分支。

  git push origin：alpha-0.3.0 
 git push origin cc4b63bebb6：refs / heads / alpha-0.3.0 
  

如果这不起作用 - 也许是因为你有 receive.denyDeletes set，那么你必须直接访问版本库。在远程存储库中，您必须执行类似下面的管道命令。

  git update-ref refs / heads / alpha -0.3.0 cc4b63bebb6 83c9191dea8 
  

Here's what I did on my supposed-to-be-stable branch...

% git rebase master
First, rewinding head to replay your work on top of it...
Fast-forwarded alpha-0.3.0 to master.
% git status
# On branch alpha-0.3.0
# Your branch is ahead of 'origin/alpha-0.3.0' by 53 commits.
#
nothing to commit (working directory clean)
% git push
Fetching remote heads...
  refs/
  refs/heads/
  refs/tags/
  refs/remotes/
'refs/heads/master': up-to-date
updating 'refs/heads/alpha-0.3.0'
  from cc4b63bebb6e6dd04407f8788938244b78c50285
  to   83c9191dea88d146400853af5eb7555f252001b0
    done
'refs/heads/unstable': up-to-date
Updating remote server info

That was all a mistake as I later realized. I'd like to undo this entire process, and revert the alpha-0.3.0 branch back to what it was.

What should I do?

解决方案

You need to make sure that no other users of this repository are fetching the incorrect changes or trying to build on top of the commits that you want removed because you are about to rewind history.

Then you need to 'force' push the old reference.

git push -f origin last_known_good_commit:branch_name

or in your case

git push -f origin cc4b63bebb6:alpha-0.3.0

You may have receive.denyNonFastForwards set on the remote repository. If this is the case, then you will get an error which includes the phrase [remote rejected].

In this scenario, you will have to delete and recreate the branch.

git push origin :alpha-0.3.0
git push origin cc4b63bebb6:refs/heads/alpha-0.3.0

If this doesn't work - perhaps because you have receive.denyDeletes set, then you have to have direct access to the repository. In the remote repository, you then have to do something like the following plumbing command.

git update-ref refs/heads/alpha-0.3.0 cc4b63bebb6 83c9191dea8
