Nguyễn Gia Phong 078e0effb7 Add memoization mechanism for file download 
This is intentionally dependent from caching, which relies on cache dir.

Tzu-ping Chung 4683ad02e3 Allow filtering constraints with markers 2020-08-07 13:55:38 +08:00
Chris Hunt 8b838ebb89 Prepare lazy wheels more so they are downloaded 
This keeps all knowledge about preparation and types of requirements in
`RequirementPreparer`, so there's one place to look when we're ready to
start breaking it apart later.

Chris Hunt f0d4df10eb Propagate lazy_wheel option through RequirementPreparer 
Reduces dependence on Candidate (and Resolver (and Factory)).

Chris Hunt e49dcfdc35 Move lazy_wheel warning out of Resolver 
This warning just needs to be traced in one place for all commands,
there's no need for the resolver to know about it. Moving the warning
out of the Resolver will make it easier to change how we provide the
option.

Nguyễn Gia Phong 5d15291274 Use lazy wheel to obtain dep info for new resolver 2020-07-21 16:00:34 +07:00
Tzu-ping Chung 01e0700e68 Skip installing if the version matches locally 
This check only applies to explicit requirements since we avoid
downloading the dist from finder altogether when there is a matching
installation (although the check wouldn’t change the behaviour in that
case anyway).

We can do this when we build the `ExplicitRequirement` instead, like how
we did for `SpecifierRequirement`, but that would require us to resolve
the direct requirement’s version eagerly, which I don’t want to.

The implemented approach checks the version only after resolution, at
which point the distribution is already built anyway and the operation
is cheap.

Tzu-ping Chung d5204dd0ba Move markers check into the ireq->req constructor 
This makes the check apply to ALL requirement constructions, no
exceptions.

Tzu-ping Chung 418d9051b8 Set max_rounds to an incredibly large number 
We really don't want to raise ResolutionTooDeep yet since the metric is
not very useful. Try to avoid this until we come up with a better method
to count.

Rewrite get_topological_weights to allow cycles 
We take the length for the longest path to any node from root, ignoring
any paths that contain any node twice (i.e. cycles).
