Merging multiple branches from same master

Question

I have created multiple branches (say, b1... bn) from same master (M).

Now, when I merge them, as the job is done, one by one, will my master become M +b1+... bn, or the last merger will overwrite the previous merges, and leave me with M + bn, and all the merges ie b1, b2 are lost?

Answer 1

如果您将 m 与 b1 合并并获得 mb1 然后将 mb1 与 b2 合并以获得 mb1b2 ... mb1b2...bi，如果您没有合并任何分支，则此类分支中的更改将不会累积反映在主分支上
