Adds support for disabling installation from pre-built wheels i.e. the
package must be built from source locally.
We will still always use pre-built wheels for metadata during
resolution.
Available via `--no-binary` and `--no-binary-package <name>` flags in
`pip install` and `pip sync`. There is no flag for `pip compile` since
no installation happens there.
```
--no-binary
Don't install pre-built wheels.
When enabled, all installed packages will be installed from a source distribution.
The resolver will still use pre-built wheels for metadata.
--no-binary-package <NO_BINARY_PACKAGE>
Don't install pre-built wheels for a specific package.
When enabled, the specified packages will be installed from a source distribution.
The resolver will still use pre-built wheels for metadata.
```
When packages are already installed, the `--no-binary` flag will have no
affect without the `--reinstall` flag. In the future, I'd like to change
this by tracking if a local distribution is from a pre-built wheel or a
locally-built wheel. However, this is significantly more complex and
different than `pip`'s behavior so deferring for now.
For reference, `pip`'s flag works as follows:
```
--no-binary <format_control>
Do not use binary packages. Can be supplied multiple times, and each time adds to the
existing value. Accepts either ":all:" to disable all binary packages, ":none:" to empty the
set (notice the colons), or one or more package names with commas between them (no colons).
Note that some packages are tricky to compile and may fail to install when this option is
used on them.
```
Note we are not matching the exact `pip` interface here because it seems
complicated to use. I think we may want to consider adjusting our
interface for this behavior since we're not entirely compatible anyway
e.g. I think `--force-build` and `--force-build-package` are clearer
names. We could also consider matching the `pip` interface or only
allowing `--no-binary <package>` for compatibility. We can of course do
whatever we want in our _own_ install interfaces later.
Additionally, we may want to further consider the semantics of
`--no-binary`. For example, if I run `pip install pydantic --no-binary`
I expect _just_ Pydantic to be installed without binaries but by default
we will build all of Pydantic's dependencies too.
This work was prompted by #895, as it is much easier to measure
performance gains from building source distributions if we have a flag
to ensure we actually build source distributions. Additionally, this is
a flag I have used frequently in production to debug packages that ship
Cythonized wheels.
Improves some of the "no versions of <package> are available" messages
by showing the complement or inversion of the package.
Does not address cases like
```
Because there are no versions of crow that satisfy any of:
crow>1.0.0,<2.0.0a5
crow>2.0.0a7,<2.0.0b1
crow>2.0.0b1,<2.0.0b5
...
```
which are a bit more complicated; I'll focus on those cases in a
follow-up.
## Summary
I don't know if this is actually a good change, but it tries to make the
editable install experience more consistent. Specifically, we now
support...
```
# Use a relative path with a `file://` prefix.
# Prior to this PR, we supported `file:../foo`, but not `file://../foo`, which felt inconsistent.
-e file://../foo
# Use environment variables with paths, not just URLs.
# Prior to this PR, we supported `file://${PROJECT_ROOT}/../foo`, but not the below.
-e ${PROJECT_ROOT}/../foo
```
Importantly, `-e file://../foo` is actually not supported by pip... `-e
file:../foo` _is_ supported though. We support both, as of this PR. Open
to feedback.
On top of https://github.com/astral-sh/puffin/pull/947, we can also box
`PrioritizedDistribution`.
In a simple benchmark, this seems to slightly improve performance when
comparing only this commit to main, even though the benchmark is too
noisy to establish significance:
```

This is https://github.com/astral-sh/puffin/pull/947 again but this time
merging into main instead of downstack, sorry for the noise.

Windows has a default stack size of 1MB, which makes puffin often fail
with stack overflows. The PR reduces stack size by three changes:
* Boxing `File` in `Dist`, reducing the size from 496 to 240.
* Boxing the largest futures.
* Boxing `CachePolicy`
## Method
Debugging happened on linux using
https://github.com/astral-sh/puffin/pull/941 to limit the stack size to
1MB. Used ran the command below.
```
RUSTFLAGS=-Zprint-type-sizes cargo +nightly build -p puffin-cli -j 1 > type-sizes.txt && top-type-sizes -w -s -h 10 < type-sizes.txt > sizes.txt
```
The main drawback is top-type-sizes not saying what the `__awaitee` is,
so it requires manually looking up with a future with matching size.
When the `brotli` features on `reqwest` is active, a lot of brotli types
show up. Toggling this feature however seems to have no effect. I assume
they are false positives since the `brotli` crate has elaborate control
about allocation. The sizes are therefore shown with the feature off.
## Results
The largest future goes from 12208B to 6416B, the largest type
(`PrioritizedDistribution`, see also #948) from 17448B to 9264B. Full
diff: https://gist.github.com/konstin/62635c0d12110a616a1b2bfcde21304f
For the second commit, i iteratively boxed the largest file until the
tests passed, then with an 800KB stack limit looked through the
backtrace of a failing test and added some more boxing.
Quick benchmarking showed no difference:
```console
$ hyperfine --warmup 2 "target/profiling/main-dev resolve meine_stadt_transparent" "target/profiling/puffin-dev resolve meine_stadt_transparent"

By default, windows has a stack size limit of 1MB which we run against
in debug without any explicit culprit. A new environment variable
`PUFFIN_STACK_SIZE` allows setting an artificially smaller stack size.
We should definitely sort this out per #863 but until then I want to
stop getting false reports of failed CI please and this seems better
than turning off the test entirely.
Alternatively #993
## Summary
I got confused by why `VerbatimUrl` was on `Path`. Since it's directly
computed from it, I think we should just compute it as-needed. I think
it's also possibly-buggy because the URL is the URL of the _directory_,
not the artifact itself, which differs from other distributions.
Missing piece for the release.

```
## Summary
This PR adds a release workflow powered by `cargo-dist`. It's similar to
the version that's PR'd in Ruff
(https://github.com/astral-sh/ruff/pull/9559), with the exception that
it doesn't include the Docker build or the "update dependents" step for
pre-commit.
## Summary
This PR is like #957, but for validating the virtual environment, rather
than the cache. So, if you have a local wheel, and you rebuild it, we'll
now correctly uninstall and reinstall it in the virtual environment.
## Summary
- This was inherited from
d719988323/src/metadata.rs (LL78C2-L91C26)
- ...which introduced this code here:
9cd1d43f7c
- ...with the originating issue here:
https://github.com/PyO3/maturin/issues/612
- ...and the upstream issue here:
https://github.com/staktrace/mailparse/issues/50
It seems like the goal was to support Unicode in certain header fields,
but I don't think this is necessary for us. We only use
`get_first_value` for `Requires-Python`, which has to be ASCII, doesn't
it?
In my testing, it seems like the `charset` hack can also be removed. The
tests I copied over actually work without it, which makes me a bit
skeptical.
The main benefit here is that we get to a remove a _big_ dependency
stack, including Chumsky and Stacker and psm which have limited
cross-platform support.
## Summary
This is a small correctness improvement that ensures that we avoid using
stale cache entries for local dependencies in the install plan. We
already have some logic like this in the source distribution builder,
but it didn't apply in the install plan, and so we'd end up using stale
wheels.
Specifically, now, if you create a new local wheel, and run `pip sync`,
we'll mark the cache entries as stale and make sure we unzip it and
install it. (If the wheel is _already_ installed, we won't reinstall it
though, which will be a separate change. This is just about reading from
the cache, not the environment.)
## Summary
This adds a benchmark in which we reuse the lockfile, but add a new
dependency to the input requirements.

Fixes#965
We have to canonicalize the interpreter path, otherwise the home is set
to the venv dir instead of the real root. This would make
python-build-standalone fail with the encodings module not being found
because its home is wrong.
