Git合并分支不成

Question

What does it mean when i look at git log and see something like this:

Merge branch 'wtf' of my.site.com:~/repo

Usually It looks like this:

Merge branch 'wtf' of my.site.com:~/repo into some-other-branch

Which makes perfect sense to me.

Note, this particular repo is in a detatched head state and has apparently been this way for some time. I suspect this is the reason for the strange commit message.

Answer 1

当当前分支是master分支时，合并提交消息中未提及该分支。

Answer 2

As explained above by phd this is the correct answer.
Let's give some more details into it.

Whenever you merge 2 or more branches and the merge will result in a merge commit (for example when --no-ff merge occurs) git will generate the commit message for you. merge commit is the case when your commits are not producing a straight line, its when you have "derived" from your main commit lines and the merge should add the code back to your "main" line. It will result in a split log graph.

The commit message will include the names of the branches in the format Merge branch X into Y . If the current branch is master, meaning that you merge code into master, git will not add the master to your commit message .
