## Summary This PR adds support for resolving and installing dependencies via direct URLs, like: ``` werkzeug @ https://files.pythonhosted.org/packages/ff/1d/960bb4017c68674a1cb099534840f18d3def3ce44aed12b5ed8b78e0153e/Werkzeug-2.0.0-py3-none-any.whl ``` These are fairly common (e.g., with `torch`), but you most often see them as Git dependencies. Broadly, structs like `RemoteDistribution` and friends are now enums that can represent either registry-based dependencies or URL-based dependencies: ```rust /// A built distribution (wheel) that exists as a remote file (e.g., on `PyPI`). #[derive(Debug, Clone)] #[allow(clippy::large_enum_variant)] pub enum RemoteDistribution { /// The distribution exists in a registry, like `PyPI`. Registry(PackageName, Version, File), /// The distribution exists at an arbitrary URL. Url(PackageName, Url), } ``` In the resolver, we now allow packages to take on an extra, optional `Url` field: ```rust #[derive(Debug, Clone, Eq, Derivative)] #[derivative(PartialEq, Hash)] pub enum PubGrubPackage { Root, Package( PackageName, Option<DistInfoName>, #[derivative(PartialEq = "ignore")] #[derivative(PartialOrd = "ignore")] #[derivative(Hash = "ignore")] Option<Url>, ), } ``` However, for the purpose of version satisfaction, we ignore the URL. This allows for the URL dependency to satisfy the transitive request in cases like: ``` flask==3.0.0 werkzeug @ https://files.pythonhosted.org/packages/c3/fc/254c3e9b5feb89ff5b9076a23218dafbc99c96ac5941e900b71206e6313b/werkzeug-3.0.1-py3-none-any.whl ``` There are a couple limitations in the current approach: - The caching for remote URLs is done separately in the resolver vs. the installer. I decided not to sweat this too much... We need to figure out caching holistically. - We don't support any sort of time-based cache for remote URLs -- they just exist forever. This will be a problem for URL dependencies, where we need some way to evict and refresh them. But I've deferred it for now. - I think I need to redo how this is modeled in the resolver, because right now, we don't detect a variety of invalid cases, e.g., providing two different URLs for a dependency, asking for a URL dependency and a _different version_ of the same dependency in the list of first-party dependencies, etc. - (We don't yet support VCS dependencies.)
