git致命：无法读取对象xxx：无效的参数 [英] git fatal: failed to read object xxx: Invalid argument

问题描述

如果我从远程访存获取以下错误：

  $ git pull 
 remote：计数对象：85，完成。 
 remote：压缩对象：100％（37/37），完成。 
 remote：合计85（增量63），重复使用69（增量48）
开箱对象：完成100％（85/85）。 
错误：inflate：数据流错误（未知压缩方法）
致命：无法读取对象8b0fd4094630fea108b60faa15535ffbc85d87cb：无效参数
错误：http://myremoterepo.com/project.git未发送所有必需的对象
  

我可以在本地提交。当我检查状态时：

 > $ git status分支vikas你的分支是基于'origin / master'，
>但上游消失了。 （使用git branch --unset-upstream到
> fixup）没有提交，工作目录干净
  

解决方案

最后我能解决这个问题。
我认为当我的电脑由于停电而关机时，问题发生了。

我能够在我的任何本地分支中提交任何更改。这意味着我的包文件没有损坏，但一些裁判无效。

首先备份您的 .git 。然后我使用 git fsck 命令

  $ git fsck --full 
错误：inflate：数据流错误（未知压缩方法）
错误：无法解压38fe6f16c7e8246d61150f0bc42629dbb532b5ce头部

我删除了文件 .git / objects / 38 / fe6f16c7e8246d61150f0bc42629dbb532b5ce 并继续执行这些步骤，直到获得以下输出：

  $ git fsck --full

现在我删除了所有三个ref（ .git / refs / remotes / origin / master ， .git / refs / remotes / origin / staging ， .git / refs / remotes / origin / development ）

瞧！现在我能够拉和推！

从此处获悉

I am getting the following error if I pull for fetch from remote

$ git pull
remote: Counting objects: 85, done.
remote: Compressing objects: 100% (37/37), done.
remote: Total 85 (delta 63), reused 69 (delta 48)

error: http://myremoterepo.com/project.git did not send all necessary objects

I can commit locally. When I check status:

> $ git status On branch vikas Your branch is based on 'origin/master',
> but the upstream is gone.   (use "git branch --unset-upstream" to
> fixup) nothing to commit, working directory clean

解决方案

Finally I was able to fix this issue. I think issue happened when my computer shutdown due to power cut.

I was able to commit any changes in any of my local branch. This means my pack file is no corrupted but some refs are invalid.

Back up your .git first. Then I use git fsck command

$ git fsck --full
error: inflate: data stream error (unknown compression method)
error: unable to unpack 38fe6f16c7e8246d61150f0bc42629dbb532b5ce header

fatal: loose object 38fe6f16c7e8246d61150f0bc42629dbb532b5ce (stored in .git/objects/38/fe6f16c7e8246d61150f0bc42629dbb532b5ce) is corrupt

I deleted the file .git/objects/38/fe6f16c7e8246d61150f0bc42629dbb532b5ce and continuing these steps until I get following output:

$ git fsck --full

...

Now I removed all three refs (.git/refs/remotes/origin/master, .git/refs/remotes/origin/staging, .git/refs/remotes/origin/development)

Voila! Now I was able to pull and push!
