从远程git存储库中恢复未提交的提交 [英] Recover unreferenced commits from remote git repository

问题描述

不幸的是，有人做了 push -f ，这样任何远程分支都不会引用这些提交。

更糟糕的是，我没有在本地克隆中提交这些提交。

我的目标基本上是恢复那些提交。这些是我尝试过的一些事情：

• git checkout -b恢复< commit_id> ：fatal：引用不是树


• git push origin< commit_id>：recovery

  
  

  错误：refs / heads / recovery没有指向有效的对象！错误：
  无法推送到不合格目标：恢复目标
  refspec既不匹配远程的现有参考，也不以
  refs /开头，我们无法根据来源引用

存储库位于bitbucket上，并且提交可以从Web界面访问，所以它没有被垃圾回收。

解决方案

问题是您的本地存储库没有该提交ID。 b

  git checkout -b恢复< commit_id> 
 git push origin< commit_id>：recovery 
  

这两个命令都因此失败，如果我使用本地不存在的提交ID，我会得到与GitHub回购完全相同的消息。

我认为答案只是简单地提取丢失的提交在本地，以下列方式之一：

  git fetch origin＃1 
 git fetch origin SHA1＃2 
 git fetch origin SHA1：refs / remotes / origin / recovery＃3 
  

不幸的是，这些工作都没有成功。根据这个答案。截至目前，它不再有效。

有一个帮助页面在GitHub上，但没有答案，你可以使用：它基本上说，如果你有你可以在本地创建一个分支并推送它。是的，但是如果你本地没有提交，那么是什么？它不会回答。

我可以考虑两种选择：

1. 找到有这个提交的队友。用 git log SHA1 检查很容易。如果任何人拥有它，他们可以使用 git分支恢复SHA1 从它创建一个分支，然后推送它。 联系bitbucket支持。因为他们有提交，所以他们应该能够为你创建一个恢复分支。

Here's the situation : some commits have been done in a remote repository.

Unfortunately, someone did push -f such that no remote branch references these commits anymore.

To make matters worse, I don't have those commits in my local clone.

My goal is basically to recover those commits. These are some of the things I tried :

• git checkout -b recovery <commit_id> : fatal: reference is not a tree
• git push origin <commit_id>:recovery

  error: refs/heads/recovery does not point to a valid object! error: unable to push to unqualified destination: recovery The destination refspec neither matches an existing ref on the remote nor begins with refs/, and we are unable to guess a prefix based on the source ref.

The repository is on bitbucket, and the commit is accessible from the web interface, so it hasn't been garbage-collected.

解决方案

The problem is that your local repository doesn't have that commit id.

git checkout -b recovery <commit_id>
git push origin <commit_id>:recovery

Both of these commands fail for that reason, I get the exact same messages with a GitHub repo if I use a commit id that doesn't exist locally.

I thought the answer will be simply fetching the lost commits locally, in one of these ways:

git fetch origin         #1
git fetch origin SHA1    #2
git fetch origin SHA1:refs/remotes/origin/recovery  #3

Unfortunately none of these work. It seems #2 used to work as of Git v1.4 according to this answer. As of now, it doesn't work anymore.

There is a help page for this on GitHub, but with no answer that you can use: it basically says that if you have the commit locally you can create a branch from it and push it. Yeah, but if you don't have the commit locally then what? It doesn't answer that.

I can think of two options:

1. Find a teammate who has this commit. It's easy to check with git log SHA1. If anybody has it, they can create a branch from it with git branch recovery SHA1 and then push it.
2. Contact bitbucket support. Since they have the commit, somewhere, they should be able to create a recovery branch for you.
