## Summary
Now, `puffin_warnings::warn_once` and `puffin_warnings::warn` will go to
`stderr`, as long as the user isn't running under `--quiet`. Previously,
these went through `tracing`, and so were only visible when running
under `--verbose`.
I saw warnings when we were e.g. unzipping wheel and setuptools in two
tasks at the same time. We now keep track of in flight unzips.
This introduces a `OnceMap` abstraction which we also use in the
resolver.
## Summary
This PR adds support for local path dependencies. The approach mostly
just falls out of our existing approach and infrastructure for Git and
URL dependencies.
Closes https://github.com/astral-sh/puffin/issues/436. (We'll open a
separate issue for editable installs.)
## Test Plan
Added `pip-compile` tests that pre-download a wheel or source
distribution, then install it via local path.
## Summary
This PR unifies the behavior that lived in the resolver's `distribution`
crates with the behaviors that were spread between the various structs
in the installer crate into a single `Fetcher` struct that is intended
to manage all interactions with distributions. Specifically, the
interface of this struct is such that it can access distribution
metadata, download distributions, return those downloads, etc., all with
a common cache.
Overall, this is mostly just DRYing up code that was repeated between
the two crates, and putting it behind a reasonable shared interface.
## Summary
This crate only contains types, and I want to introduce a new crate for
all _operations_ on distributions, so this feels like a more natural
name given we also have `pypi-types`.

Extends #424 with support for URL dependency incompatibilities.
Requires changes to `miette` to prevent URLs from being word wrapped;
accepted upstream in https://github.com/zkat/miette/pull/321
Always¹ clear the temporary directories we create.
* Clear source dist downloads: Previously, the temporary directories
would remain in the cache dir, now they are cleared properly
* Clear wheel file downloads: Delete the `.whl` file, we only need to
cache the unpacked wheel
* Consistent handling of cache arguments: Abstract the handling for CLI
cache args away, again making sure we remove the `--no-cache` temp dir.
There are no more `into_path()` calls that persist `TempDir`s that i
could find.
¹Assuming drop is run, and deleting the directory doesn't silently
error.
A fork will let us stay up to date with the upstream while replaying our
work on top of it.
I expect a similar workflow to the RustPython-Parser fork we maintained,
except that I wrote an automation to create tags for each commit on the
fork (https://github.com/zanieb/pubgrub/pull/2) so we do not need to
manually tag and document each commit.
To update with the upstream:
- Rebase our fork's `main` branch on top of the latest changes in
upstream's `dev` branch
- Force push, overwriting our `main` branch history
- Change the commit hash here to the last commit on `main` in our fork
Since we automatically tag each commit on the fork, we should never lose
the commits that are dropped from `main` during rebase.
This works by filtering out files with a more recent upload time, so if
the index you use does not provide upload times, the results might be
inaccurate. pypi provides upload times for all files. This is, the field
is non-nullable in the warehouse schema, but the simple API PEP does not
know this field.
If you have only pypi dependencies, this means deterministic,
reproducible(!) resolution. We could try doing the same for git repos
but it doesn't seem worth the effort, i'd recommend pinning commits
since git histories are arbitrarily malleable and also if you care about
reproducibility and such you such not use git dependencies but a custom
index.
Timestamps are given either as RFC 3339 timestamps such as
`2006-12-02T02:07:43Z` or as UTC dates in the same format such as
`2006-12-02`. Dates are interpreted as including this day, i.e. until
midnight UTC that day. Date only is required to make this ergonomic and
midnight seems like an ergonomic choice.

I was moved to do this because I noticed `malloc`/`free` taking up a
fairly sizeable percentage of time during light profiling.
As is becoming a pattern, it will be easier to review this
commit-by-commit.
Ref #396 (wouldn't call this issue fixed)
-----
I did also try adding a `smallvec` optimization to the
`Version::release` field, but it didn't bare any fruit. I still think
there is more to explore since the results I observed don't quite line
up with what I expect. (So probably either my mental model is off or my
measurement process is flawed.) You can see that attempt with a little
more explanation here:
https://github.com/astral-sh/puffin/commit/f9528b4ecd1b0c260df7e8ad57b9ddc4da09d273
In the course of adding the `smallvec` optimization, I also shrunk the
`Version` fields from a `usize` to a `u32`. They should at least be a
fixed size integer since version numbers aren't used to index memory,
and I shrunk it to `u32` since it seems reasonable to assume that all
version numbers will be smaller than `2^32`.
Ran `cargo upgrade --incompatible`, seems there are no changes required.

`which` 5.0.0 seems to have only error message changes.
The normalized name abstractions were not consistently, this PR uses
them where they were previously missing:
* `WheelFilename::distribution`
* `Requirement::name`
* `Requirement::extras`
* `Metadata21::name`
* `Metadata21::provides_dist`
With `puffin-package` depending on `pep508_rs` this would be cyclical
crate dependency, so `puffin-normalize` gets split out from
`puffin-package`.
`DistInfoName` has the same task and semantics as `PackageName`, so it's
merged into the latter.
`PackageName` and `ExtraName` documentation is moved onto the type and
their constructors are called `new` instead of `normalize`. We now use
these constructors rarely enough the implicit allocation by
`to_string()` shouldn't matter anymore, while more actual cloning
becomes visible.
This also allows us to get rid of `PinnedPackage` _and_ to remove some
`Result<...>` types due to needless conversions between
otherwise-identical types.
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)
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.
This needs far better error handling and user-facing feedback, but it
does the basic operation (and includes discovery of the `pyproject.toml`
file, etc.).
This PR modifies the `install-wheel-rs` (and a few other crates) to get
everything playing nicely. Specifically, CI should pass, and all these
crates now use workspace dependencies between one another.
As part of this change, I split out the wheel name parsing into its own
`wheel-filename` crate, and the compatibility tag parsing into its own
`platform-tags` crate.
This PR modifies the PEP 440 and PEP 508 crates to pass CI, primarily by
fixing all lint violations.
We're also now using these crates in the workspace via `path`.
(Previously, we were still fetching them from Cargo.)
