GIT恢复上次分离的HEAD [英] GIT restore last detached HEAD

问题描述

请在我的项目中遇到一个大问题：这是场景。
我有一个GIT下的xcode项目。今天我意识到最后一次提交会破坏一些测试，所以我检查了之前的提交。
我使用SourceTree，这是warnig

这样做会使您的工作副本成为'分离的HEAD'，这意味着您将不再在分支上。如果你想在这之后提交，你可能想要再次签出一个分支，或者创建一个新的分支。这是正常的吗？

我工作了一整天，最后我承诺一切。
所以我需要合并我在开发分支上的工作，所以我检查开发分支，并且...我的工作立即消失：（b / b）

我知道错了分离我的头和Sourcetree警告我...但有一种方法可以恢复我的作品？

非常感谢。

git reflog ，它会显示修订版本的历史 HEAD / code>指向。你的分离的头应该在那里。一旦你找到它，做 git checkout -b my-new-branch abc123 或 git branch my-new-branch abc123 （其中 abc123 是detached HEAD的SHA-1）创建一个新分支，指向你已分离的头部，现在你可以在闲暇时合并该分支。

一般来说，如果你在分离的头部上工作后检查一个分支，Git应该告诉你来自已经分离的头部的提交，所以如果需要的话可以恢复它。我从来没有使用过SourceTree，所以我不会知道它是否转发该消息。但是如果它显示了这条消息，那么你应该可以使用它来找到提交，并再次使用 git checkout -b 或 git分支从该提交中创建一个分支。

Please, I have a big problem in my project: this is the scenario. I have an xcode project under GIT. Today i realized that the last commit breaks some tests, so i checkout the previous commit. I use SourceTree and this is the warnig

Doing so will make your working copy a 'detached HEAD', which means you won't be on a branch anymore. If you want to commit after this you'll probably want to either checkout a branch again, or create a new branch. Is this ok?

I worked for an entire day and at the end i committed everything. So i needed to merge my work on develop branch so i checkout the develop branch and...my work instantly disappear :(

I know was wrong to detach my HEAD and Sourcetree warned me...but there is a way to restore my works?

thanks a lot.

解决方案

If you type git reflog, it will show you the history of what revisions HEAD pointed to. Your detached head should be in there. Once you find it, do git checkout -b my-new-branch abc123 or git branch my-new-branch abc123 (where abc123 is the SHA-1 of the detached HEAD) to create a new branch that points to your detached head. Now you can merge that branch at your leisure.

Generally, if you check out a branch after working on a detached head, Git should tell you the commit from the detached head you had been on, so you can recover it if you need. I've never used SourceTree, so I don't know if it relays that message. But if it did display that message, then you should be able to use that to find the commit, and again use git checkout -b or git branch to create a branch from that commit.
