我该如何恢复我的Git存储库以查找“缺失的树”错误？ [英] How can I recover my Git repository for a "missing tree" error?

问题描述

我们正在使用Gerrit作为我们的Git存储库。在一个活动了好几个月的项目上，我们突然无法推动任何改变。当我们执行 git push 时，我们看到如下错误：
$ b

error：unpack failed：错误树14d62f0ed4385e3f68f226ac133fa9932a9c65c9

执行 git fsck --full yield：

我们所有的开发者elopers在尝试推送时遇到同样的错误。到目前为止，我们已经尝试重新初始化gerrit repo（git init --bare ...）并推动它。我们也尝试使用单独的回购来创建新的gerrit项目。最后，我们不断收到相同的错误。

有没有人知道原因是什么，或者如何恢复？

$ b $使用 git push --no-thin 而不是 git push 。

从Git文档：

当发送者和接收者共享许多相同的对象时发送的数据量。默认值是--thin。

We are using Gerrit for our Git repository. On a project that has been active for several months, we are suddenly unable to push any changes. When we execute git push we see the following error:

error: unpack failed: error Missing tree 14d62f0ed4385e3f68f226ac133fa9932a9c65c9

Executing git fsck --full yields:

All of our developers are experiencing the same error when they try to push. So far, we've tried re-initializing the gerrit repo (git init --bare ...) and pushing up to it. We've also tried creating a new gerrit project with a separate repo. In the end, we keep getting the same error.

Does anyone have any insight on what the cause would be, or how to recover?

解决方案

Use git push --no-thin instead of git push.

From Git docs:

A thin transfer significantly reduces the amount of sent data when the sender and receiver share many of the same objects in common. The default is --thin.
