Build PR branches only once (for origin branches) and skip docs changes

[joerick]

My PR branches get built twice on some CI services (Appveyor, Travis, Github), once for the PR and once for the branch. This disables the branch build, for anything other than master, to save some CI time.

Also, on services that support it, I've disabled docs changes from needing CI runs.

But I sometimes test in my own repository (development only on one system). So this configuration may introduce additional, obsolete PR.

So you have your own CI services set up on your fork?

yes. Github actions are enabled out of box based on .github/workflow directory.

EDIT:
For example In #307 I test subprocess.run on windows without shell on my own branch and base on result I found this bug with PATH ignore.

[joerick]

Okay, you'd have to enable those yourself by deleting this change if you have a branch that you want test on.

And there isn't a way to ignore PRs coming from the same repo (rather than pushes to branches in the repo)?

[joerick]

I don't think so, but I had an idea- you could test your personal branches by raising a PR to your own fork's master branch, rather than upstream master

basing on https://help.github.com/en/actions/reference/workflow-syntax-for-github-actions#jobsjob_idif
https://help.github.com/en/actions/reference/context-and-expression-syntax-for-github-actions and https://help.github.com/en/actions/reference/context-and-expression-syntax-for-github-actions#github-context

In github workflow it maybe something like

jobs:
  test:
  if: github.repository != 'joerick/cibuildwheel' || github.ref == master || github.event_name == 'pull_request'

[joerick]

Ah, okay, I'll give that a shot.
