close/reopen to retrigger CI

[mattip]

ahh, finally got appveyor integration working here 👍

[multibuilder]

I was too optmistic. The build is stuck on setting up the conda environment

[cclauss]

Each test will timeout after 60 minutes. Perhaps go to https://ci.appveyor.com/project/multibuild/multibuild/settings and set the build timeout to 5 or 10 minutes and let's see if any Python passes the test.

I set the timeout to 10 minutes

Comment out the failing tests so we have a working CI...

• Python 2.7 32-bit fails but 64-bit passes.
• Python 3.6 fails but 3.5 and 3.7 pass.

This may change if the image: is set to something more modern than the current Visual Studio 2015.

Sounds reasonable, we should be using 2017 at the very least

[cclauss]

Please kill jobs 1.0.2 - 1.0.7 at https://ci.appveyor.com/project/multibuilder/multibuild/history

But allow 1.0.8 and 1.0.9 to run to completion.

[mattip]

Done

[cclauss]

Whack 1.0.7 too, please.

[mattip]

right now 1.0.9 is running

[cclauss]

Fascinating... 1.0.8 ran on my AppVeyor but failed on yours...

[mattip]

For now I have updated settings to allow User to run builds

[cclauss]

Steps forward...

• Land this PR so we have tests that pass while we enhance.
• Upgrade image: https://www.appveyor.com/docs/windows-images-software 2019 or 2022?
• Try to re-enable Pythons. Do we want to stick to supported branches or support legacy too?
• Test on Linux and macOS on AppVeyor or on GitHub Actions?

Test on Linux and macOS on AppVeyor or on GitHub Actions?

I would prefer github actions, using the test.yml that I added a few hours ago.

Try to re-enable Pythons. Do we want to stick to supported branches or support legacy too?

We should still support python2.7, and probably python3.6 as well. I think we can drop python3.5, python3.4 and the older macOS<10.9. @matthew-brett thoughts?

[cclauss]

Just for the record... Python 2 died 776 days ago on 1/1/2020 but we can support it if desired.

Thanks @cclauss, let's put this in, like you say, to have at least one passing test
