问题描述
恢复已提交的 git 合并同时保留稍后合并同一分支的选项的最佳方法是什么?
What's the best way to revert a committed git merge while keeping the option of merging the same branch at a later point?
这是一种情况，当我将一个分支合并到 HEAD 中，然后决定我目前不想要这些更改，但仍然希望在以后的某个时间选择将它们合并到 HEAD.
This is for a situation when I merge a branch into HEAD, then decide that I do not want these changes at the present, but still want the option to merge them into HEAD at some later point.
"git revert -m 1" 将代码恢复到合并前的状态，但分支仍然以某种方式标记为已经合并".因此，稍后与同一分支重复合并是行不通的.
"git revert -m 1" reverts the code to the pre-merge state, but the branch is still somehow marked as "already merged". So a repeated merge with the same branch at a later point does not work.
这应该是一个非常普遍的问题(而且 git 是一个进化的工具)，但我找不到一个简单干净的解决方案(除了销毁 git 存储库并再次从远程拉取它).我错过了什么吗?
This should be a very common problem (and git is an evolved tool), yet I cannot find a simple clean solution (apart from destroying the git repository and pulling it from remote again). Am I missing something?
推荐答案
很抱歉，你浪费了你的分支.
Sorry to say that you have wasted your branch.
但是有一个解决方法.诀窍是暂时重写"合并提交，以便它忘记分支是父分支.假设 X 是合并提交:
But there is a workaround. The trick is to "rewrite" the merge commit temporarily so that it forgets that the branch is a parent. Assume X is the merge commit:
git replace --graft X X^ # pretend that there is just one parent
git merge branch # merge the branch again
git replace --delete X # remove the replacement
