将大型Git存储库分割成许多较小的 [英] Split large Git repository into many smaller ones

问题描述

因此，在成功将SVN存储库转换为Git后，我现在有一个非常大的Git存储库，我想分解成多个较小的存储库并保留历史记录。 ，有人可以帮助分解可能看起来像这样的回购：

  MyHugeRepo / 
 .git / 
 DIR_A / 
 DIR_B / 
 DIR_1 / 
 DIR_2 / 
  

进入如下所示的两个存储库：

  MyABRepo / 
 .git 
 DIR_A / 
 DIR_B / 
 
 My12Repo / 
 .git 
 DIR_1 / 
 DIR_2 / 
  

我尝试了以上问题中的以下指示，但在尝试将多个目录放入单独的repo时并不适合（将子目录分离（移动）到单独的Git存储库中）。

解决方案

这会设置MyABRepo;当然也可以做类似My12Repo。

  git clone MyHugeRepo / MyABRepo.tmp / 
 cd MyABRepo.tmp 
 git filter-branch --prune-empty --index-filter'git rm --cached --ignore-unmatch DIR_1 / * DIR_2 / *'HEAD 
  

对.git / refs / original / refs / heads / master的引用仍然存在。您可以删除它：

  cd .. 
 git clone MyABRepo.tmp MyABRepo 
 
 code> 

如果一切顺利，您可以删除MyABRepo.tmp。

---

如果由于某种原因你得到一个关于.git-rewrite的错误，你可以试试这个：

  git clone MyHugeRepo / MyABRepo.tmp / 
 cd MyABRepo.tmp 
 git filter-branch -d /tmp/git-rewrite.tmp --prune-empty --index-filter'git rm --cached --ignore-unmatch DIR_1 / * DIR_2 / *'HEAD 
 cd .. 
 git clone MyABRepo.tmp MyABRepo 
  

这将创建并使用/tmp/git-rewrite.tmp作为临时目录，而不是 .git-rewrite 。
当然，只要你有写权限，而且目录没有，你可以替换你想要的任何路径而不是 /tmp/git-rewrite.tmp 已经存在。

After successfully converting an SVN repository to Git, I now have a very large Git repository that I want to break down into multiple smaller repositories and maintain history.

So, can someone help with breaking up a repo that might look like this:

MyHugeRepo/
   .git/
   DIR_A/
   DIR_B/
   DIR_1/
   DIR_2/

Into two repositories that look like this:

MyABRepo/
   .git
   DIR_A/
   DIR_B/

My12Repo/
   .git
   DIR_1/
   DIR_2/

I've tried following directions in this previous question but it doesn't really fit when trying to put multiple directories into a separate repo (Detach (move) subdirectory into separate Git repository).

解决方案

This will setup MyABRepo; you can do My12Repo similarly of course.

git clone MyHugeRepo/ MyABRepo.tmp/
cd MyABRepo.tmp
git filter-branch --prune-empty --index-filter 'git rm --cached --ignore-unmatch DIR_1/* DIR_2/*' HEAD 

A reference to .git/refs/original/refs/heads/master remains. You can remove that up with:

cd ..
git clone MyABRepo.tmp MyABRepo

If all went well you can then remove MyABRepo.tmp.

---

If for some reason you get an error regarding .git-rewrite, you can try this:

git clone MyHugeRepo/ MyABRepo.tmp/
cd MyABRepo.tmp
git filter-branch -d /tmp/git-rewrite.tmp --prune-empty --index-filter 'git rm --cached --ignore-unmatch DIR_1/* DIR_2/*' HEAD 
cd ..
git clone MyABRepo.tmp MyABRepo

This will create and use /tmp/git-rewrite.tmp as a temporary directory, instead of .git-rewrite. Naturally, you can substitute any path you wish instead of /tmp/git-rewrite.tmp, so long as you have write permission, and the directory does not already exist.
