Preventing master CI run when a commit a made on a feature branch

Currently, when I push a commit to a feature branch (linked to a Github PR), appveyor triggers two builds – one for the commit on the PR, and another one for the commit against master. How do I prevent the latter?

My appveyor.yml doesn't specificy this, since I want the feature branches to build.

branches:
  only:
    - master

Thanks

   Could you please elaborate scenario a little bit? My understanding is the following:

   • You created initial PR
     • Both feature and master branch builds triggered and this is OK
   • You created another commit to the same feature branch
     • Both feature and master branch builds triggered but this time you what it happen only in feature branch

   Is my understanding correct?

   So say I have a branch X. I push a commit to that branch X. I want only that branch X to build, not master. In case a PR has been created for that branch I want it to behave in the same way (i.e. only branch X should build).

   When this PR gets merged into master, only then master should build.

   How do I do this?

   OK, now I understand. We have opposite feature, option to set Do not build feature branches with open Pull Requests. We might think of implementing something like *Do not build virtual merge on *, can you please provide some business justification, in what scenario you do not need virtual merge?

   As workaround we can propose to edit YAML only in feature branch to have
   

   branches:
     only:
       - <feature_branch>
   

   and then revert this change before merge. Changes in YAML themselves can be done with [skip ci] or [ci skip] anywhere to commit message, to avoid triggering unneeded builds. I admin that this is not most elegant solution though...

   Our test phase is a heavy weight and un-conventional. It tests the building
   of images etc. We use the GH PR feature which checks that the PR must
   update with the master before the merge can happen. This ensures the PR is
   update with master before a merge, and that a corresponding CI run against
   the latest master has happened. So, we would like the flexibility to not
   run the virtual merges on every commit on a feature branch, and instead
   rely on the CI run triggered by the commit of master merging into the
   feature branch.

   Do you need this for clean build history, or to free up number of parallel jobs? If later, you can also call one of exit commands at init stage if APPVEYOR_REPO_BRANCH is master and APPVEYOR_PULL_REQUEST_NUMBER is not NULL (or DEFINED if you use CMD). Job will be stopped immediately, though some time will be still lost on job/VM creation.
   In any case I created GH issue to track this feature request.
