git repo 损坏的问题

Problems with corrupt git repo

提问by epsilones

My git repo got corrupted while running a find and replace command (See here: Git reset failing after find and replace). So I deleted some pack files about which git told me that there were not reachable. So I ran rm ./.git/index, git reset. When running git commit, I got this message :

我的 git 存储库在运行查找和替换命令时损坏（请参阅此处：查找和替换后 Git 重置失败）。所以我删除了一些 git 告诉我无法访问的包文件。所以我运行 rm ./.git/index, git reset。运行 git commit 时，我收到以下消息：

fatal: corrupt tree sha $someSHA

Finally git fsck, my working directory went clean and I was able to commit. The pb now is that when I run git checkout some_other_branch, I got this message

最后 git fsck，我的工作目录变得干净，我能够提交。现在的 pb 是当我运行 git checkout some_other_branch 时，我收到了这条消息

fatal: unable to read tree $someSHA

(The $someSHA appearing are the same). Someone could help me ?

（出现的 $someSHA 是相同的）。有人可以帮助我吗？

First: Make a backup of your .gitdirectory in case you corrupt things more in this process. Then:

第一：备份您的.git目录，以防您在此过程中损坏更多内容。然后：

• Put back the best version of the packfiles you have available.

• For each of the corrupt packfiles, run:

  mv .git/objects/pack/pack-**yourpack**.pack oldpack
  git unpack-objects -r < oldpack
  

• Run git fsck --fulland git checkoutagain, give us the output.

• Looks like now you should be able to check out, but you will have to run git checkout -f **yourbranch**, as you have changes in your working dir that are not yet committed. These changes will get lost when you run git checkout -f, though.

• 放回可用的包文件的最佳版本。

• 对于每个损坏的包文件，运行：

  mv .git/objects/pack/pack-**yourpack**.pack oldpack
  git unpack-objects -r < oldpack
  

• 运行git fsck --full并git checkout再次，给我们的输出。

• 看起来现在您应该可以检出，但是您必须运行git checkout -f **yourbranch**，因为您的工作目录中有尚未提交的更改。git checkout -f但是，当您运行 时，这些更改将丢失。
