Subject: bpo-40275: test.support.check_impl_detail() uses sys.implementation (GH-20468)
X-Git-Tag: v3.10.0a1~792
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=b0461e19b5ecb2d89917b23efb5ce1048fab1b22;p=thirdparty%2FPython%2Fcpython.git

bpo-40275: test.support.check_impl_detail() uses sys.implementation (GH-20468)

check_impl_detail() of test.support now uses sys.implementation.name,
instead of platform.python_implementation().lower(). This change
prepares test.support to import the platform module lazily.
