[PyQt] Versioning wheels

[Eduard Babayan]

Hello

Starting from pyqt5 version 5.7 wheels now include 2 versions. Recent ones
look like this
: PyQt5-5.11.3-5.11.2_a-cp35.cp36.cp37.cp38-abi3-macosx_10_6_intel.whl

I noticed because it broke version parsing automation in my company. Now
that is not that important of course. But still there are questions

Can anyone shed some light on why wheels include 2 versions? Also Pip
cannot parse second version and if it's for humans the use still
unclear. Latter
is especially strange for names like in example above containing two patch
versions 5.11.3. And 5.11.2. Why not have only one.

Thanks.

Regards
Eduard

The first is the PyQt version, the second is the Qt version bundled in
it.

The '5.11.3' is the version number of PyQt.

The '5.11.2_a' is the build tag. pip should have no problem parsing it.

See...

https://www.python.org/dev/peps/pep-0427/#file-name-convention

For PyQt the build tag is made up of the version of Qt included in the wheel (ie. 5.11.2 in this case) optionally followed by an underscore and a letter (ie. '_a' in this case). The letter allows the release a new wheels to replace previous ones for the same PyQt and Qt versions.
