pytest_cov.__version__ string is broken on >=2.10.1

[christophebedard]

Summary

Expected vs actual result

I expect pytest_cov.__version__ == 'x.y.z', but as of 2.10.1 it's pytest_cov.__version__ == "__version__ = 'x.y.z'": da61b91#diff-cfb899e3f5cac1afba8f5bafcd74392faf2677836ed2f3b068217df610ea6e82R2

This broke code that relied on the version string. There's no explanation in the CHANGELOG:

pytest-cov/CHANGELOG.rst

Lines 36 to 42 in 2cd0094

	2.10.1 (2020-08-14)
	-------------------
	* Support for ``pytest-xdist`` 2.0, which breaks compatibility with ``pytest-xdist`` before 1.22.3 (from 2017).
	Contributed by Zac Hatfield-Dodds in `#412 <https://github.com/pytest-dev/pytest-cov/pull/412>`_.
	* Fixed the ``LocalPath has no attribute startswith`` failure that occurred when using the ``pytester`` plugin
	in inline mode.

Looking at PEP 396 I'm not sure this is valid: https://www.python.org/dev/peps/pep-0396/#id27

Assuming this was not intentional, I think this might be caused by a tooling bug. A few commits before 2.10.1 was tagged, this config file here for bumping the version number was changed: https://github.com/pytest-dev/pytest-cov/pull/420/files#diff-9ea6e1e3dde6d4a7e08c7c88eceed69ca745d0d2c779f8f85219b22266efff7f (c4b0722).

I'll try to fix it.

An unfortunate consequence of me using old bumpversion and messing up the quotes :-(

[christophebedard]

😆 thanks for fixing it!

[dirk-thomas]

Thanks for addressing this. Will there a new patch release with this fix in the near future?

[ionelmc]

Yes, yes. Gonna sort it out this week.
