Git：如何在特定提交之前删除历史记录 [英] Git: how to remove history before a specific commit

问题描述

  root  -  c1  -  c2  -  ..  -  c1000  -  c1001  - c1002  -  ..  -  c2000  -  top 
  

我想要：

  root = c1000  -  c1001  -  c1002  -  ..  -  c2000  -  top 
  
 p> 
 
 
如何？
 
 
 
（我想我可以通过 git filter ）
 
 
 
（当然我知道这意味着历史重写...）
解决方案
最简单的方法是使用git嫁接。如果您编辑.git / info / grafts文件，您可以将行放入格式文件中。 
 
 
  [ref] [parent1] [ parent2] ...  
 
 
 
然后将左侧引用的任何提交视为右侧列出的父代是承诺。因此，您可以插入一行，如 
 
 
  c1000  
 
 
 
它会被视为没有父母。然后可以通过运行git-filter-branch来烘焙。
 
I.e., I have:
root -- c1 -- c2 -- .. - c1000 -- c1001 -- c1002 -- .. -- c2000 -- top
and I want to have:
root = c1000 -- c1001 -- c1002 -- .. -- c2000 -- top
How?

(I guess I can do via git filter-branch, but how exactly?)

(Of course I know that this means history-rewriting...)
解决方案
Easiest way is with a git graft. If you edit the file .git/info/grafts, you can put lines in the file of the format 

[ref] [parent1] [parent2] ...

Any commits referenced on the left side are then treated as if the parents listed on the right are the parents of that commit. So you can insert a line like

c1000

and it will be treated as though it has no parents. This can then be "baked in stone" by running git-filter-branch.
