Fixes #1192
packaging.specifiers.SpecifierSet
(ireq.specifier
) provides equality andhash definition that are based on a canonical specifier representation.
Basing RequirementSummary equality and hash on those allows to easily
side-step any version/specifier normalization concerns on our side.
Effectively, makes equality and hash of
test_package==1.2.0
andtest_package==1.2
to be the same, as expected.Changelog-friendly one-liner: Fix pip 20.2 compatibility issue that caused pip-tools to sometime fail to stabilize in a constant number of rounds.
