We have been provided with https://python.visualstudio.com/cpython and a measure of build machines to help us run continuous integration builds. The benefits are more reliable builds (especially Mac and Windows) and higher parallelism than our current services.

My PR adds the build definition files and fixes some test bugs to ensure we can successfully test on this platform. There are a few more manual steps to make it work against our repo, which we will do immediately after merging the changes.

Can you explain what Visual Studio Team Services is?

[brettcannon]

https://www.visualstudio.com/team-services/

It's Microsoft's GitHub hosting, issue tracking, and CI/CD platform.

This is implemented and merged now. I'll leave it to core-workflow to decide whether and when to make the builds required and/or reduce use of Travis/AppVeyor.

[gpshead]

Your PRs made modifications to code and did not include a useful commit message or appropriate NEWS entries for the code modifications.

Further, VSTS is unreliable. core-workflow made a premature decision to turn off Travis and AppVeyor and make VSTS blocking.

[ammaraskar]

core-workflow made a premature decision to turn off Travis and AppVeyor and make VSTS blocking.

It looks like AppVeyor and Travis are still running as of the latest PR: #6965

Annoyingly, I don't think there's a way to make certain checks like VSTS be optional and not show up with a red cross on Github.

Hi Steve

I just saw VSTS in action, it's a great job, thank you.

Compared to Travis-CI:

• is there more computers for the tests on VSTS?

• with time, what will be the reference if there is a 'green' build? TravisCI or VSTS?

Thank you again for the job.
