Extends #254
Adds validation of extra names provided by users in `pip-compile` e.g.
```
error: invalid value 'foo!' for '--extra <EXTRA>': Extra names must start and end with a
letter or digit and may only contain -, _, ., and alphanumeric characters
```
We'll want to add something similar to `PackageName`. I'd be curious to
improve the AP, making the unvalidated nature of `::normalize` clear?
Perhaps worth pursuing later though as I don't have a better idea.
## Summary
This PR adds support for resolving and installing dependencies via
direct URLs, like:
```
werkzeug @ 960bb4017c/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 @ 254c3e9b5f/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.)
Tests would sometimes flake with this locally e.g. "1.50s" was not
filtered correctly.

This also allows us to get rid of `PinnedPackage` _and_ to remove some
`Result<...>` types due to needless conversions between
otherwise-identical types.
Extends #253Closes#241
Adds `extras` to `RequirementsSpecification` to track extras used to
construct the requirements so we can throw an error when not all of the
requested extras are used.
Going to add some tests.
Extends #239Closes#245
Normalizes optional dependency group names found in pyproject files
before comparing them to the normalized user-requested extras.
Adds support for `pip-compile --extra <name> ...` which includes
optional dependencies in the specified group in the resolution.
Following precedent in `pip-compile`, if a given extra is not found,
there is no error. ~We could consider warning in this case.~ We should
probably add an error but it expands scope and will be considered
separately in #241
We now accept a pre-release if (1) all versions are pre-releases, or (2)
there was a pre-release marker in the dependency specifiers for a direct
dependency.
The code is written such that we can support a variety of pre-release
strategies.
Closes https://github.com/astral-sh/puffin/issues/191.
To check to top 1k (current state):
```bash
scripts/resolve/get_pypi_top_8k.sh
cargo run --bin puffin-dev -- resolve-many scripts/resolve/pypi_top_8k_flat.txt --limit 1000
```
Results:
```
Errors: pywin32, geoip2, maxminddb, pypika, dirac
Success: 995, Error: 5
```
pywin32 has no solution for the build environment, 3 have no
`[build-system]` entry in pyproject.toml, `dirac` is missing cmake
Like `pip-compile`, we now respect existing versions from the
`requirements.txt` provided via `--output-file`, unless you pass a
`--upgrade` flag.
Closes#166.
Previously, we had two python interpreter metadata structs, one in
gourgeist and one in puffin. Both would spawn a subprocess to query
overlapping metadata and both would appear in the cli crate, if you
weren't careful you could even have to different base interpreters at
once. This change unifies this to one set of metadata, queried and
cached once.
Another effect of this crate is proper separation of python interpreter
and venv. A base interpreter (such as `/usr/bin/python/`, but also pyenv
and conda installed python) has a set of metadata. A venv has a root and
inherits the base python metadata except for `sys.prefix`, which unlike
`sys.base_prefix`, gets set to the venv root. From the root and the
interpreter info we can compute the paths inside the venv. We can reuse
the interpreter info of the base interpreter when creating a venv
without having to query the newly created `python`.
This is isn't ready, but it can resolve
`meine_stadt_transparent==0.2.14`.
The source distributions are currently being built serially one after
the other, i don't know if that is incidentally due to the resolution
order, because sdist building is blocking or because of something in the
resolver that could be improved.
It's a bit annoying that the thing that was supposed to do http requests
now suddenly also has to a whole download/unpack/resolve/install/build
routine, it messes up the type hierarchy. The much bigger problem though
is avoid recursive crate dependencies, it's the reason for the callback
and for splitting the builder into two crates (badly named atm)
As elsewhere, we just use the `pip` and `pip-compile` APIs. So we
support `--index-url` to override PyPI, then `--extra-index-url` to add
_additional_ indexes, and `--no-index` to avoid hitting the index at
all.
Closes#156.
Allows the user to select between clone, hardlink, and copy semantics
for installs. (The pnpm documentation has a decent description of what
these mean: https://pnpm.io/npmrc#package-import-method.)
Closes#159.
Borrows terminology from pnpm by introducing three resolution modes:
- "Highest": always choose the highest compliant version (default).
- "Lowest": always choose the lowest compliant version.
- "LowestDirect": choose the lowest compliant version of direct
dependencies, and the highest compliant version of any transitive
dependencies. (This makes a bit more sense than "lowest".)
Closes https://github.com/astral-sh/puffin/issues/142.
Builds up a complete resolved graph from PubGrub, and shows the sources
that led to each package being included in the resolution, like
`pip-compile`.
Closes https://github.com/astral-sh/puffin/issues/60.
Gets rid of the custom `DistInfo` struct in the site-packages
abstraction in favor of a new kind of distribution
(`InstalledDistribution`). No change in behavior.
This is also a lot faster. Unfortunately it copies a lot of code from
the sync cli since the `Printer` is private.
The first commit are some refactorings i made when i thought about how i
could reuse the existing code.
