我有一个类似的问题。我的笔记本电脑在git操作期间电量耗尽。嘘
我没有任何备份。(注意,Ubuntu One不是git的备份解决方案;它将用损坏的存储库有帮助地覆盖您的健全存储库。)
对于git向导,如果这是修复它的不好方法,请发表评论。但是,它确实为我工作了……至少是暂时的。
步骤1:备份.git(实际上,我在每次更改后的步骤之间都执行此操作,但要使用新的复制到名称,例如.git-old-1,.git-old-2等)。 :
cp -a .git .git-old
步骤2:执行 git fsck --full
nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git fsck --full
error: object file .git/objects/8b/61d0135d3195966b443f6c73fb68466264c68e is empty
fatal: loose object 8b61d0135d3195966b443f6c73fb68466264c68e (stored in .git/objects/8b/61d0135d3195966b443f6c73fb68466264c68e) is corrupt
步骤3:删除空文件。我想通了。还是空白。
nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ rm .git/objects/8b/61d0135d3195966b443f6c73fb68466264c68e
rm: remove write-protected regular empty file `.git/objects/8b/61d0135d3195966b443f6c73fb68466264c68e'? y
步骤3:git fsck
再次运行。继续删除空文件。您还可以cd
进入.git
目录并运行find . -type f -empty -delete -print
以删除所有空文件。最终git开始告诉我它实际上是在处理对象目录:
nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git fsck --full
Checking object directories: 100% (256/256), done.
error: object file .git/objects/e0/cbccee33aea970f4887194047141f79a363636 is empty
fatal: loose object e0cbccee33aea970f4887194047141f79a363636 (stored in .git/objects/e0/cbccee33aea970f4887194047141f79a363636) is corrupt
步骤4:删除所有空文件后,我最终开始git fsck
实际运行:
nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git fsck --full
Checking object directories: 100% (256/256), done.
error: HEAD: invalid sha1 pointer af9fc0c5939eee40f6be2ed66381d74ec2be895f
error: refs/heads/master does not point to a valid object!
error: refs/heads/master.u1conflict does not point to a valid object!

missing blob e4cf65ddf80338d50ecd4abcf1caf1de3127c229
步骤5:尝试git reflog
。失败,因为我的头坏了。
nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git reflog
fatal: bad object HEAD
步骤6:Google。找到这个。手动获取reflog的最后两行:
nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ tail -n 2 .git/logs/refs/heads/master
f2d4c4868ec7719317a8fce9dc18c4f2e00ede04 9f0abf890b113a287e10d56b66dbab66adc1662d Nathan VanHoudnos <nathanvan@gmail.com> 1347306977 -0400 commit: up to p. 24, including correcting spelling of my name
9f0abf890b113a287e10d56b66dbab66adc1662d af9fc0c5939eee40f6be2ed66381d74ec2be895f Nathan VanHoudnos <nathanvan@gmail.com> 1347358589 -0400 commit: fixed up to page 28
步骤7:请注意,从步骤6中我们了解到HEAD当前指向最后的提交。因此,让我们尝试仅查看父提交:
nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git show 9f0abf890b113a287e10d56b66dbab66adc1662d
commit 9f0abf890b113a287e10d56b66dbab66adc1662d
Author: Nathan VanHoudnos <nathanvan@XXXXXX>
Date: Mon Sep 10 15:56:17 2012 -0400
up to p. 24, including correcting spelling of my name
diff --git a/tex/MCMC-in-IRT.tex b/tex/MCMC-in-IRT.tex
index 86e67a1..b860686 100644
--- a/tex/MCMC-in-IRT.tex
+++ b/tex/MCMC-in-IRT.tex
有效!
步骤8:所以现在我们需要将HEAD指向9f0abf890b113a287e10d56b66dbab66adc1662d。
nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git update-ref HEAD 9f0abf890b113a287e10d56b66dbab66adc1662d
哪个没抱怨。
步骤9:看看fsck怎么说:
nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git fsck --full
Checking object directories: 100% (256/256), done.
error: refs/heads/master.u1conflict does not point to a valid object!
error: 0e31469d372551bb2f51a186fa32795e39f94d5c: invalid sha1 pointer in cache-tree
dangling blob 03511c9868b5dbac4ef1343956776ac508c7c2a2
missing blob 8b61d0135d3195966b443f6c73fb68466264c68e
missing blob e89896b1282fbae6cf046bf21b62dd275aaa32f4
dangling blob dd09f7f1f033632b7ef90876d6802f5b5fede79a
missing blob caab8e3d18f2b8c8947f79af7885cdeeeae192fd
missing blob e4cf65ddf80338d50ecd4abcf1caf1de3127c229
步骤10:高速缓存树中的无效sha1指针似乎是来自(现已过时)索引文件(source)的。所以我杀了它并重置了仓库。
nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ rm .git/index
nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git reset
Unstaged changes after reset:
M tex/MCMC-in-IRT.tex
M tex/recipe-example/build-example-plots.R
M tex/recipe-example/build-failure-plots.R
步骤11:再次查看fsck ...
nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git fsck --full
Checking object directories: 100% (256/256), done.
error: refs/heads/master.u1conflict does not point to a valid object!
dangling blob 03511c9868b5dbac4ef1343956776ac508c7c2a2
dangling blob dd09f7f1f033632b7ef90876d6802f5b5fede79a
在晃来晃去斑点不是错误。我不关心master.u1冲突,现在它可以正常工作了,我不想再碰它了!
第12步:掌握本地编辑信息:
nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git status
# On branch master
# Changes not staged for commit:
# (use "git add <file>..." to update what will be committed)
# (use "git checkout -- <file>..." to discard changes in working directory)
#

# modified: tex/recipe-example/build-example-plots.R
# modified: tex/recipe-example/build-failure-plots.R
#
