The contents of this attribute are an implementation detail, as
documented for #9442, so we should not parse it, to support non-CPython
VMs with distutils2 in the future.
Unfortunately, one use comes directly from PEP 345, so an edit will have
to be agreed before fixing the code (see comment in p7g.markers).
Other remaining uses are found in p7g.compiler and could be replaced by
the platform module (which also parses sys.version, but then it wouldn’t
be my fault :)
- minor cleanup in Metadata
- trigger creation of the sysconfig._CONFIG_VARS dict
- home_page is used over home-page: it’s not a compound word, it’s an
escaped space
Distutils2 is now synchronized with Packaging.
This change also makes sure the logger handlers are not alterated after an
installation. That also fixes the remaining environment alteration issue in
test_packaging.
