git错误：对象文件为空（object-file-is-empty）的解决方案

背景介绍

在日常开发过程中我们可能因为操作不当导致git版本库出问题，最经常出的一个问题就是对象文件为空错误object-file-is-empty，一般提示如下所示：

error: object file .git/objects/31/65329bb680e30595f242b7c4d8406ca63eeab0 is empty
fatal: loose object 3165329bb680e30595f242b7c4d8406ca63eeab0 (stored in .git/objects/31/65329bb680e30595f242b7c4d8406ca63eeab0) is corrupt

最优解决方案

1.运行 git fsck --full

luyi@ubuntu:~/projects/example$ git fsck --full
error: object file .git/objects/3a/60046cdd45cf3e943d1294b3cb251a63fb9552 is empty
error: object file .git/objects/3a/60046cdd45cf3e943d1294b3cb251a63fb9552 is empty
fatal: loose object 3a60046cdd45cf3e943d1294b3cb251a63fb9552 (stored in .git/objects/3a/60046cdd45cf3e943d1294b3cb251a63fb9552) is corrupt

2. 选中空文件，删除 rm filepath

luyi@ubuntu:~/projects/example$ rm .git/objects/3a/60046cdd45cf3e943d1294b3cb251a63fb9552
rm: remove write-protected regular empty file ‘.git/objects/3a/60046cdd45cf3e943d1294b3cb251a63fb9552’? y

3.再次运行 git fsck --full 一般会检查到另外一个新的空文件，再删之。一劳永逸的办法就是在.git目录下find . -type f -empty -delete -print 会删除全部空文件

luyi@ubuntu:~/projects/example/.git$ find . -type f -empty -delete -print
./objects/c6/492f7ad72197e2fb247dcb7d9215035acdca7f
./objects/9f/fe81f4bb7367c00539a9a0d366ff2a7558bfed
./objects/7c/b9a39246389a8417006b9365f6136823034110
./objects/de/1092e8c90cb025e99501a4be0035753b259572
./objects/6f/a8c9109f2e0d29095490ca8f4eaf024a6e2dcb

4.至此，所有空文件删除完毕，再运行 git fsck --full，还是有错，head指向元素不存在，是之前一个空文件，我们已经删了。肿么办呢？

luyi@ubuntu:~/projects/example/.git$ git fsck --full

5.手动获得最后两条reflog ,运行tail -n 2 .git/logs/refs/heads/ia

luyi@ubuntu:~/projects/example$ tail -n 2 .git/logs/refs/heads/ia
3a0ecb6511eb0815eb49a0939073ee8ac8674f8a 99cb711e331e1a2f9b0d2b1d27b3cdff8bbe0ba5 卢祎 <luy@jjmmw.com> 1477039998 +0800    commit: nested into app

6.head当前是指向最新的那一条记录，所以我们看一下parent commit 即倒数第二条提交 git show 99cb711e331e1a2f9b0d2b1d27b3cdff8bbe0ba5

luyi@ubuntu:~/projects/example$ git show 99cb711e331e1a2f9b0d2b1d27b3cdff8bbe0ba5commit 99cb711e331e1a2f9b0d2b1d27b3cdff8bbe0ba5
Date:   Fri Oct 21 16:53:18 2016 +0800

    nested into app

diff --git a/pzbm/templates/pzbm/base.html b/pzbm/templates/pzbm/base.html
index 70331c5..c96d12c 100644
--- a/pzbm/templates/pzbm/base.html
+++ b/pzbm/templates/pzbm/base.html
@@ -6,7 +6,7 @@

我们可以看到内容，是好着的

7.那么我们就重新设置head,使其指向倒数第二条 git update-ref HEAD 99cb711e331e1a2f9b0d2b1d27b3cdff8bbe0ba5

luyi@ubuntu:~/projects/example$ git update-ref HEAD 99cb711e331e1a2f9b0d2b1d27b3cdff8bbe0ba5
