Rolling builds not very useful

We tried to use rolling builds to manage a queue of builds, but it resulted in builds we did not want to be cancelled to be cancelled. In a private project, it would cancel all but the latest build regardless of branch. So we would end of with no build for the latest changes in several branches. We would prefer that it cancel duplicate builds per branch.

On a opensource project the problem was similar, here is what the person who manages that project said:

Here is my PR for which the rolling build never worked correctly. Appveyor kept cancelling all my commit builds (even manual)

Looks like the rolling build is not very reliable.

    OK, do you have a suggestion on how to improve them?

    Add an option to do basically the same thing but keeping one build per branch (treating a PR on github as a different branch)

    This would save us a few builds, not a lot, but anything that helps...

    Well, looking at the implementation of rolling builds... this is actually how they are supposed to work. If you start a new master build all other "master" builds will be cancelled; if you start a new "some_other_branch" build all other "some_other_branch" builds will be cancelled, but not "master" ones. The same for PRs, but PR # is the key there. Do you observe a different behavior?

    I think the rolling builds do work as Feodor explained.

    The rolling builds work also for pull requests.

    So, I think there is no issue any more.
