Add Python 3.10 to CI

[frenck]

Breaking change

The following integrations have been disabled because they have incompatible Python dependencies for Home Assistant.

• apcupd
• apns
• xbee

Proposed change

Adds Python 3.10 to the CI

Notes:

• zwave has now commented dependencies, and tests are disabled. This allows us to ship it with Python 3.9, but not block Python 3.10
• icloud tests have been disabled, as those are currently not yet 3.10 compatible. Can be enabled again once we bump pyicloud.

Problematic packages:

• pyhton-nest -> nest integration.
  Update for python3.10 moving Callable usage to collections.abc jkoelker/python-nest#174

  'collections' has no attribute 'Callable'
  nest/nest.py:159

I've spend some time today looking into it. Some things I noticed which could be helpful in getting this PR done.

• Due to a bug in the vendored packaging lib, pip versions prior to 20.3.2 won't install wheels from PyPI even if they have been uploaded. Update packaging version to install Python 3.10 wheels. pypa/pip#9272
  The main issue for us is that 20.3 introduced the new dependency resolver which doesn't yet work for us. For < 21.0, e.g 20.3.4, it's possible to add --use-deprecated=legacy-resolver to pip install to still use the old resolver. The other option would obviously be fixing Upgrade to newer Python pip>=21.0 #59769 but that might take some time.
• Pandas started uploading wheels for all major platforms only with >= 1.3.4 (for Python 3.10). Looking at the changelog, both 1.3.4 and 1.3.5 should be compatible with 1.3.0.
• We currently pin grpcio==1.31.0 which seems to be incompatible with Python 3.10. Just looking at PyPI, version 1.41.0 seems to be the first for which the maintainers uploaded wheels.
• homeassistant-pyozw is incompatible, too. I haven't looked at it that closely, but from what I've seen it used cython. Thus it might be possible to rebuild it with a new cython version without much effort. Then again, the integration is officially deprecated, not sure it's worth it anymore.
• I initially had some issues building both numpy and pandas with Github actions. Installing software-properties-common in addition to cmake helped.

If you're only interested in the prepare-tests step for Python 3.10, you could use some temporary commands to speed up testing.

• Adding continue-on-error: true to the Create full Python ${{ matrix.python-version }} virtual environment step will store the wheel cache. Just make sure to disable the Restore full Python ${{ matrix.python-version }} virtual environment step, otherwise it won't do anything. As the prepare-tests will never fail, I would also suggest adding if: false to the pytest job temporarily.

Hope these help 🤞🏻

Pandas started uploading wheels for all major platforms only with >= 1.3.4 (for Python 3.10). Looking at the changelog, both 1.3.4 and 1.3.5 should be compatible with 1.3.0.

The pandas constrain was here because of Alpine 3.13, which we no longer have. The constrain has been lifted in this PR.

We currently pin grpcio==1.31.0 which seems to be incompatible with Python 3.10. Just looking at PyPI, version 1.41.0 seems to be the first for which the maintainers uploaded wheels.

Currently in progress. As a matter of fact, we have released a new wheels builder today that should deal with the last bits of issues we had. We are currently at our third attempt to update to 1.43.0 (thanks to @allenporter for that effort).

Ref: #63911

homeassistant-pyozw is incompatible, too. I haven't looked at it that closely, but from what I've seen it used cython. Thus it might be possible to rebuild it with a new cython version without much effort. Then again, the integration is officially deprecated, not sure it's worth it anymore.

The integration will be removed. This has been discussed already.

Not an issue here.

If you're only interested in the prepare-tests step for Python 3.10, you could use some temporary commands to speed up testing.

Not in a hurry. This will not be merged this release anyways, so we have over 1,5 months left ish to make it in time for 2022.3 (that is not a hard deadline though).

The other option would obviously be fixing Upgrade to newer Python pip #59769 but that might take some time.

PS: I've "resolved" that one locally (Well threw out anything that would cause an issue, just to get somewhere workable), however, it takes pip over 12 hours to resolve our full dependency tree (on an AMD Ryzen 7 machine). Which is not a workable solution.

😮 Ok, yeah 12h is indeed too long. Maybe a naive idea, what about this? (Assuming we start from a no-conflicts state.)
Dependency resolution likely only takes this long as pip constantly backtracks and installs multiple different versions in the process. It should be possible to speed this up by pinning every dependency from the start . I.e. use the output of pip freeze as constraints file.

Let's next say we want to update a "normal" dependency. Pip should be able to check fairly quickly if there are any conflicts with the given constraints. If there are, the next step would be to loosen only the conflicting dependency in the requirements file and try again to see if pip can find a solution now. Afterwards update the constraints.

At first this is a much more manual process, but maybe steps could be automated as part of the CI pipeline.

Something like pip-compile with its --upgrade-package option could also work. Although you might have already tried that one. https://pip-tools.readthedocs.io/en/latest/

The fact we even need to consider those tools is just too stupid to put into words.

For hyperframe:
The requirement probably needs to be >=6.0. Version 5.2 still uses the removed import.
https://github.com/python-hyper/hyperframe/blob/v5.2.0/hyperframe/flags.py#L10-L14

Regarding the apns tests:
If you don't want to remove them just yet, you could skip the file for pytest.
https://docs.pytest.org/en/latest/how-to/skipping.html#summary

[frenck]

Regarding the apns tests

The integration is pending deletion and has 0 active users according to statistics. I think we can safely remove it 😉

The requirement probably needs to be >=6.0

We can't, as we need <6.0. Additionally, 5.2.0 imports it conditionally, works :)

Got confused with the line number there. The invalid use was in L14, same as the conditional import.
