今天执行`git pull`时遇到麻烦，应该是昨天电脑异常关机造成的git数据损坏：

$git pull
    error: object file .git/objects/88/526655aa4eca14ead2d443e80082276a79e0c2 is empty
    error: object file .git/objects/88/526655aa4eca14ead2d443e80082276a79e0c2 is empty
    fatal: loose object 88526655aa4eca14ead2d443e80082276a79e0c2 (stored in .git/objects/88/526655aa4eca14ead2d443e80082276a79e0c2) is corrupt
    fatal: The remote end hung up unexpectedly

这种情况以前也偶尔遇到过，我当时的解决办法又笨又简单，就是删除当前代码重新从远程仓库下载一份代码，反正只要确保远程仓库是最新完整的代码就没问题。  
这次不同了，本地有不少花时间生成的中间结果代码，删除之后重建要花时间，所以就不想用这么笨的办法。  
在stackoverflow上找到这篇文章[《how to fix GIT error: object file is empty?》][how to fix GIT error_ object file is empty]，几个answer提供了不同的解决方式，第一种方法，好烦好复杂，看不下去，后来发现国内不少翻译这篇文章的帖子，介绍的就是第一种方法。

而第二个answer提供的方法就简单明白许多，过程就三步：

![在这里插入图片描述][70]

于是尝试用这个办法：

step1:  
删除所有因为数据损坏导致的空对象文件(remove any empty object files)。执行第一步没有任何输出

$ find .git/objects/ -type f -empty | xargs rm

step2:  
下载上一步删除的对象文件(fetch down the missing objects)

$ git fetch -p
    error: refs/heads/master does not point to a valid object!
    error: refs/remotes/origin/master does not point to a valid object!
    error: refs/heads/master does not point to a valid object!

step3:  
做一次全面的存储对象检查(do a full object store check)

$ git fsck --full

    Checking objects: 100% (6619/6619), done.

三步完成之后，再次执行`git pull`，错误消失，成功。
