[Python] Windows wheel cannot be installed on Python 3.8

[asfimport]

λ pip install C:\tmp\arrow-verify-release-wheels\pyarrow-0.16.0-cp38-cp38m-win_amd64.whl ERROR: pyarrow-0.16.0-cp38-cp38m-win_amd64.whl is not a supported wheel on this platform.

The wheel came from

https://bintray.com/apache/arrow/download_file?file_path=python-rc%2F0.16.0-rc2%2Fpyarrow-0.16.0-cp38-cp38m-win_amd64.whl

The "m" ABI tag appears to have been removed in Python 3.8

pypa/setuptools#1822

Locally I have pip 20.0.2, wheel 0.34.1, and setuptools 45.1.0.post20200127

Krisztian Szucs / @kszucs:
@wesm These wheels have not been uploaded to pypi https://pypi.org/project/pyarrow/#files

If I recall correctly the ABI tag issue was fixed during the release process and the cp38m wheels were not removed from bintray.

I suggest to simply delete the cp38m wheels from both bintray channels.

Wes McKinney / @wesm:
Does the one on PyPI work? Will this happen again in the next release? I lost track of the resolution

[asfimport]

Neal Richardson / @nealrichardson:
IIRC we fixed this by removing the version pin on whatever python build tools package we are using (maybe it was wheel, I don't remember). The "m" issue had been fixed upstream already but we were stuck on an old version. So it should not happen in the next release.

Krisztian Szucs / @kszucs:
Here is the discussion where we applied the fix after the release 0.16 release and I manually uploaded the new ones: #6353 (comment)

Despite that I managed to manually delete the windows wheels with the previous (wrong) abi tag seems like bintray has kept them.

Wes McKinney / @wesm:
Alright, but bintray only contains the RC's right? So having a "dirty" RC is not really a big deal as long as it doesn't happen again next time

[asfimport]

Krisztian Szucs / @kszucs:
Bintray have both rc and "official" release artifacts, people use pypi for installing wheels so it should not cause problems.

[asfimport]

Wes McKinney / @wesm:
What is the status of this?

[asfimport]

Krisztian Szucs / @kszucs:
I've removed the dirty pyarrow-0.16.0-cp38-cp38m-win_amd64.* files from the 0.16 bintray release, but I left them under the 0.16.0-rc2 tag.
