Each cache entry is ~1 GB of our allotted 10 GB for the repository which
is quite a bit. We're probably losing cache entries all the time since
we add an entry per commit per pull request.
Saving the cache takes ~3 minutes
([example](2035812496)),
it's probably just slowing down CI. It's ~25% of our test runtime and
~50% of our clippy runtime.
Reduces the number of implementation branches handling `Range:full`,
deferring it to `PackageRange`.
Improves some user-facing messages, e.g. saying `all versions of
<package>` instead of `<package>*`.
Changes the member names of the `PackageRangeKind` enum — they were not
very clear.
## Summary
Installs the seed packages you get with `virtualenv`, but opt-in rather
than opt-out.
Closes https://github.com/astral-sh/puffin/issues/852.

## Summary
Our current setup uses the legacy `setup.py`-based builds if a
`pyproject.toml` file isn't present. This matches pip's behavior.
However, `pypa/build` uses PEP 517-based builds in such cases, and it
looks like pip plans to make that the default
(https://github.com/pypa/pip/issues/9175), with the limiting factor
being performance issues related to isolated builds.
This is now the default behavior, but the `--legacy-setup-py` flag
allows users to opt-in to using `setup.py` directly for distributions
that lack a `pyproject.toml`.
## Summary
This PR adds support for `prepare_metadata_for_build_wheel`, which
allows us to determine source distribution metadata without building the
source distribution. This represents an optimization for the resolver,
as we can skip the expensive build phase for build backends that support
it.
For reference, `prepare_metadata_for_build_wheel` seems to be supported
by:
- `hatchling` (as of
[1.0.9](https://hatch.pypa.io/latest/history/hatchling/#hatchling-v1.9.0)).
- `flit`
- `setuptools`
In fact, it seems to work for every backend _except_ those using legacy
`setup.py`.
Closes#599.
Refactoring split out from find links support: Find links files can be
represented as `Dist`, but not really as `File`, they don't have url nor
hashes.
`DistRequiresPython` is somewhat odd as an in between type.
Changes `File::size` from a `usize` to a `u64`.
The motivations are that with tensorflow wheels being 475 MB
(https://pypi.org/project/tensorflow/2.15.0.post1/#files), we're already
only one order of magnitude away and to avoid target dependent failures.
## Summary
If pre-releases are available for a package that we otherwise couldn't
resolve, we now show a hint that includes one of the example versions.
Closes https://github.com/astral-sh/puffin/issues/811.
Instead of trying to fixup _all_ the invalid version specifiers on pypi
and elsewhere, this filters out distributions with invalid
`requires-python` version specifiers that even
`LenientVersionSpecifiers` couldn't parse, as opposed to failing
entirely, which we currently do.
I would be nicer to model through an invalid distribution pubgrub type,
together with e.g. source dists with an unknown extension, so that the
version itself still shows up in the error trace.
At the same time, we reduce the log level for fixups from warning to
trace, as they are not actionable for the user.
Adjusts display of "no versions available" in error messages to be
consistent with other package/range pairings i.e. we usually display
"<package-name><range>".
## Summary
Right now, both the callback _and_ the "We have no compatible wheel"
paths have a lot of repeated code. This PR changes the callback to
_just_ remove all the wheels and handle the download, and the rest of
the method following the callback is responsible for finding and
building any wheels.
## Summary
I'm unable to run `puffin-cli` on `main` as the
`tracing-durations-export` is marked as optional, but the crate actually
depends on it to compile. Further, without `tracing-durations-export`,
there are `Option` types that can't resolve to a concrete type.
This PR fixes compilation with and without the feature.
Noticed these when working on something unrelated. Generally:
- Prefer `entry.file_type()` over `entry.path().is_file()` or similar,
as the former is almost always free on Unix.
- Call `entry.path()` once, since it allocates internally (returns a
`PathBuf`).
In the past, I moved us to `owo-colors`
(https://github.com/astral-sh/puffin/pull/121); then, we moved back,
because we ran into issues with overriding the settings to force-disable
colors. But `anstream` solved those problems, so I'm moving us _back_ to
`owo-colors`, since it's what `anstream` recommends, and it's already
used by many of our dependencies (`miette`, `configparser`).

## Summary
We can use `anstream` for all color control, rather than going through
`colored`. Note that we still need the `colored` crate, since `colored`
and `anstream` solve different problems. (`anstream` recommends using
`owo-colors` alongside it, but `colored` seems to work fine?)
Resolves the issue raised in
https://github.com/astral-sh/puffin/pull/742 via `anstream` rather than
`colored`.
Closes https://github.com/astral-sh/puffin/issues/782.
## Summary
Refactors the benchmark script such that we use a single `hyperfine`
invocation per benchmark, and thus get the comparative summary, which is
_way_ nicer:
```
Benchmark 1: ./target/release/puffin (install-cold)
Time (mean ± σ): 410.3 ms ± 19.9 ms [User: 173.7 ms, System: 1314.5 ms]
Range (min … max): 389.7 ms … 452.1 ms 10 runs
Benchmark 2: ./target/release/baseline (install-cold)
Time (mean ± σ): 418.2 ms ± 14.4 ms [User: 210.7 ms, System: 1246.0 ms]
Range (min … max): 397.3 ms … 445.7 ms 10 runs
Summary
'./target/release/puffin (install-cold)' ran
1.02 ± 0.06 times faster than './target/release/baseline (install-cold)'
```
Taking some of Zanie's suggestions to make the custom-path API simpler
in the benchmark script. Each tool is now a dedicated argument, like:
```
python -m scripts.bench --pip-sync --poetry requirements.in
```
To provide custom binaries:
```
python -m scripts.bench \
--puffin-path ./target/release/puffin \
--puffin-path ./target/release/baseline \
requirements.in
```
