如何获取合并分支从哪里分配的提交 [英] How to get commit where merged branch forked from

问题描述

o---1---o---o---o---o     master
     \         /
      o---o---2           feature

是否可以在不使用reflog的情况下获得提交1？
使用git 2.4.2

Is it possible to get commit 1 without using reflog ? Using git 2.4.2

我试过了：

I tried:

git merge-base master feature
git merge-base feature master
returns: commit 2 
git merge-base --fork-point master feature
git merge-base --fork-point feature master
returns nothing ( exit code 1 )

我有点困惑，这不是默认的git的一部分。您至少会期望这将是 merge-base 的 - fork-point 选项的行为。如果有人知道更好/默认的选择。请把它放在评论或作为一个单独的答案！

I am somewhat baffled that this is not part of git as default. You would at least expect that this would be the behavior of the --fork-point option for merge-base. If anyone knows a better/default alternative. Please put it in the comments or as a separate answer !
