Github pull request to a deleted branch

Question

I'm not sure how this would play out in Github and I don't want to mess up things so I wonder if you can answer this.

I have the following branches in my repo:

master
|
|
|
*   
|\  branch A - New branch for bigger framework changes
| |
| |
| |
| *
| |
| |
| |
| *   
| |\  branch B - New feature branch depending on the bigger framework changes
| | | 
| | |
| | |
| | * 
| | |

I'm done with the work with both Branch A and B , they are pushed to Github. I created a pull request of Branch A (compared to master). I'm about to create another pull request of Branch B compared to Branch A to get my changes revised. What happens if Branch A gets merged to master and the branch is deleted? Will I be able to merge Branch B from the original pull request or I'll need to open a new one comparing Branch B to the master?

Answer 1

If A is getting merged into master before B , then you should open the pull request from branch B to master. Otherwise you can request B be merged into A and then both into master .

Github just recently added support for showing 'deleted' branches, but I wouldn't count on it for a proper workflow.
