[Python-Dev] [Python-checkins] bpo-33522: Enable CI builds onVisual Studio Team Services (GH-6865) (GH-6925)


Fair point. It was because the new platforms are not identical to any of our existing ones and so exposed gaps in our tests (and one wart in tempfile, which I had explicitly reviewed by two others and gave its own bug and NEWS item).

Pre-squashing, the change had nearly 100 attempts at resolving them all, and I saw no value in cluttering the main history with them for a not-yet-approved CI system, and also no possibility of it ever being approved if there were test failures.

Happy to discuss any particular changes if you have specific concerns.

Why did this commit modify .py files, unittests, and test.support?

That is inappropriate for something claiming to merely enable a CI platform.
