Git-如何将分支拆分为其自己的存储库? [英] Git - How to split a branch to it's own repository?

问题描述

我有一个存储库，其中某个分支( admin )已从 develop 分支出来.看起来大概是这样

I have a repository where a branch (admin) has been branched out from develop at some point. It looks roughly like this

develop            c2        c4        c5
      *------------*---------*---------*------------...
      c1            \ 
                     \____________________*c3
                          admin

我希望developer分支保持不变，而admin分支应该拥有自己的存储库.作为记录，我使用的是sourcetree + bitbucket.

I want the develop branch to stay the same and admin branch should have it's own repository. For the record, I'm using sourcetree+bitbucket.

我尝试了此答案，并尝试了 git push url://to/new/repository.git admin:develop .在我的新仓库中，它的历史是从对开发(c1)的第一次提交开始的.在新的存储库中看起来像这样.

I tried the method mentioned in this answer and tried git push url://to/new/repository.git admin:develop. What it did in my new repo is that the history started from the first commit of develop (c1). it looks like this in the new repository.

c1      c2                           c3
*-------*----------------------------*
             develop

但是我想从c2启动这个新的存储库.这是正常行为还是我做错了什么?达到预期效果的正确方法是什么?

I wanted to start this new repository from c2 however. Is it normal behavior or have I done somthing wrong? What's the correct way to achieve desired result?

推荐答案

git checkout -b sliced-admin admin                   # start with admin
git rev-list develop.. | tail -1 >.git/info/grafts   # slice out the develop history
git filter-branch                                    # .
rm .git/info/grafts                                  # .

现在将sliced-admin分支推到您想要的任何地方

Now push the sliced-admin branch wherever you want

git push u://r/l sliced-admin:itsnamethere
