Resolves: python-poetry/poetry#5902 and partially python-poetry/poetry#2415
An alternative solution to python-poetry/poetry#5902 as proposed in python-poetry/poetry#5903.
Currently poetry re-downloads direct origin packages multiple times during locking because the deferred cache used to store downloaded packages is indexed using a dependency object with an explicit constraint while the lookup is done with a dependency object with an unbounded constraint which do not test equal.
This PR solves that issue by changing the
__eq__
equality check for direct origin dependencies to not consider the constraint. This should pose no problems since direct origin dependencies pointing to the same origin implicitly have the same constraint.Should I add a test for this or do we consider this an implementation detail for the sake of our current caching mechanism?
