腐败git repo的问题

Question

运行查找和替换命令时,我的git repo损坏了(参见此处:查找和替换后Git重置失败).所以我删除了一些包文件,告诉我哪些git告诉我无法访问.所以我运行了rm ./.git/index,git reset.运行git commit时,我收到了以下消息:

fatal: corrupt tree sha $someSHA

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

fatal: unable to read tree $someSHA

(出现的$ someSHA是相同的).有人可以帮帮我吗？

当我运行git fsck --full时,我得到了一个系列

error: refs/remotes/repo0/master does not point to a valid object!
error: refs/remotes/repo1/new-version does not point to a valid object!
...

然后是一系列的

broken link from    tree d935b909f76ea92728d71038d0a67384353e65e1
              to    blob 05b97658ebd47fee25b76d80ac76cbd07d77961d
...

然后一些失踪的斑点......

我运行了git log --raw --all --full-history - subdir/my-file,我得到了

error: refs/remotes/repo0/master does not point to a valid object!
error: refs/remotes/repo1/new-version does not point to a valid object!
...
error: Could not read 9096eb9d9dcbdf15a04e0a7c78a3744936f82ac7

我跑了git fsck --full,我得到了很多线

error: packfile .git/objects/pack/pack-fbfd8042e1e96bf5ffff88f9b5a230b8f5e4d4c4.pack does not match index
fatal: packfile .git/objects/pack/pack-fbfd8042e1e96bf5ffff88f9b5a230b8f5e4d4c4.pack cannot be accessed
...

当跑到git checkout另一个分支时,我得到了很多消息:

error: packfile .git/objects/pack/pack-3e7a0c040a5e3d1c21b91256d583424d82a59706.pack does not match index
warning: packfile .git/objects/pack/pack-3e7a0c040a5e3d1c21b91256d583424d82a59706.pack cannot be accessed

按照建议的答案,我解压缩文件,当我签出时,我得到一些行如下:

error: packfile .git/objects/pack/pack-fbfd8042e1e96bf5ffff88f9b5a230b8f5e4d4c4.pack does not match index
warning: packfile .git/objects/pack/pack-fbfd8042e1e96bf5ffff88f9b5a230b8f5e4d4c4.pack cannot be accesse....

然后是一系列以

 error: Your local changes to the following files would be overwritten by checkout:
.idea_local_work/.name
.idea_local_work/libraries/sass_stdlib.xml
.idea_local_work/scopes/scope_settings.xml
... and then aborting

Answer 1

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:

• 放回您可用的最佳版本的packfiles.

• 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.

• 看起来你现在应该可以退房了,但是你必须运行git checkout -f **yourbranch**,因为你的工作目录中有尚未提交的更改.git checkout -f但是,当您运行时,这些更改将会丢失.
