Scott schafer got me the idea: We can avoid repeating the path for
workspaces dependencies everywhere if we declare them in the virtual
package once and treat them as workspace dependencies from there on.
It is a common pattern to have an active conda base env (that sets
`CONDA_PREFIX`) and then create a venv on top of that (setting
`VIRTUAL_ENV`).
Previously, we would error when both `VIRTUAL_ENV` and `CONDA_PREFIX`
were set, now `VIRTUAL_ENV` takes precedence over `CONDA_PREFIX`.
Fixes#2028
## Summary
We would like to be able to configure the installer-name so that other
tools can co-exist with `uv`. In `pixi` we would like to use `pixi-uv`
as the installer name, for example, to be able to distinguish them from
packages installed by pure `uv`.
## Summary
This PR changes our user-facing representation for paths to use relative
paths, when the path is within the current working directory. This
mirrors what we do in Ruff. (If the path is _outside_ the current
working directory, we print an absolute path.)
Before:
```shell
❯ uv venv .venv2
Using Python 3.12.2 interpreter at: /Users/crmarsh/workspace/uv/.venv/bin/python3
Creating virtualenv at: .venv2
Activate with: source .venv2/bin/activate
```
After:
```shell
❯ cargo run venv .venv2
Finished dev [unoptimized + debuginfo] target(s) in 0.15s
Running `target/debug/uv venv .venv2`
Using Python 3.12.2 interpreter at: .venv/bin/python3
Creating virtualenv at: .venv2
Activate with: source .venv2/bin/activate
```
Note that we still want to use the existing `.simplified_display()`
anywhere that the path is being simplified, but _still_ intended for
machine consumption (e.g., when passing to `.current_dir()`).

## Summary
If you have a file `typing.py` in the current working directory, `python
-m` doesn't work in some Python versions:
```sh
❯ python -m foo
Could not import runpy module
Traceback (most recent call last):
File "/Users/crmarsh/.local/share/rtx/installs/python/3.9.18/lib/python3.9/runpy.py", line 15, in <module>
import importlib.util
File "/Users/crmarsh/.local/share/rtx/installs/python/3.9.18/lib/python3.9/importlib/util.py", line 2, in <module>
from . import abc
File "/Users/crmarsh/.local/share/rtx/installs/python/3.9.18/lib/python3.9/importlib/abc.py", line 17, in <module>
from typing import Protocol, runtime_checkable
ImportError: cannot import name 'Protocol' from 'typing' (/Users/crmarsh/workspace/uv/typing.py)
```
This did _not_ cause problems for us on Python 3.11 or later, because we
set `PYTHONSAFEPATH`, which avoids adding the current working directory
to `sys.path`. However, on earlier versions, we _were_ failing with the
above. (It's important that we run interpreter discovery in the current
working directory, since doing otherwise breaks pyenv shims.)
The fix implemented here uses `-I` to run Python in isolated mode, which
is even stricter. The downside of isolated mode is that we currently
rely on setting `PYTHONPATH` to find the "fake module" that we create on
disk, and `-I` means `PYTHONPATH` is totally ignored. So, instead, we
run a script directly, and that _script_ injects the path we care about
into `PYTHONSAFEPATH`.
Closes https://github.com/astral-sh/uv/issues/2547.

## Summary
We strip extras by default, but there are some valid use-cases in which
they're required (see the linked issue). This PR doesn't change our
default, but it does add `--no-strip-extras`, which lets users preserve
extras in the output requirements.
Closes https://github.com/astral-sh/uv/issues/1595.
## Summary
We had the right fixup for `torchsde`, but a subsequent fixup was making
it invalid. In general, we should apply as few of these as we can, so
lets stop as soon as we succeed.
Closes https://github.com/astral-sh/uv/issues/2546.
## Test Plan

## Summary
I tried out `cargo shear` to see if there are any unused dependencies
that `cargo udeps` isn't reporting. It turned out, there are a few. This
PR removes those dependencies.
## Test Plan
`cargo build`
## Summary
In reality, there's no such thing as the `site-packages` directory for a
given virtualenv. Rather, Python defines both `purelib` and `platlib`,
where the former is for pure-Python packages and the latter is for
packages that contain native code. These are almost always set to the
same thing... but they don't _have_ to be, and in fact of Fedora they
are not.
This PR changes the `site_packages` method to return an iterator of
directories.
Closes https://github.com/astral-sh/uv/issues/2527.
## Summary
When a user runs with `--output-file` and `--generate-hashes`, we should
_only_ update the hashes if the pinned version itself changes.

This PR handles the fragment part of the URL path.
It achieves this by splitting the fragment from the path before
normalization and parsing. It then sets the fragment back after the URL
has been parsed.
Resolve#2501
Brings us in-line with Python's behavior:
1. Prioritize `none` tags _after_ all of the relevant platform tags
2. Omit `none` tags for CPython versions less than the current version
3. Prioritize major (i.e. `py3-none`) version tags over minor (i.e.
`py3x-none`) version tags less than the current version
4. Add a `none-any` tag for the current CPython version
## Test plan
Tested on my Linux machine with a script to emit tags at the desired
glibc version:
```python
from packaging import tags
import re
exclude = re.compile("_(21|22|23|24|25|26|27|28|29|30|31|32|33|34|35|36|37|38|39)_")
for tag in tags.sys_tags():
if exclude.search(str(tag)):
continue
print(tag)
```
Then performed a diff with the snapshot in `tags.rs`
## Summary
Closes#1958
This adds linehaul metadata to uv's user-agent when pep 508 markers are
provided to the RegistryClientBuilder. Thanks to #2381, we were able to
leverage most information from markers and avoid inconsistency.
Linehaul is meant to be accompanying metadata pip sends in it's user
agent when talking to registries. You can see this output by running
something like `python -c 'from pip._internal.network.session import
user_agent; print(user_agent())'`.
In PyPI, this metadata processed by the
[linehaul-cloud-function](https://github.com/pypi/linehaul-cloud-function).
More info about linehaul can be found in #1958.
Below are some examples from pip:
* Linux GHA: `pip/24.0

Here's how uv results look like (sorry for the keys not having the same
order):
* Linux GHA: `uv/0.1.21
{"installer":{"name":"uv","version":"0.1.21"},"python":"3.12.2","implementation":{"name":"CPython","version":"3.12.2"},"distro":{"name":"Ubuntu","version":"22.04","id":"jammy","libc":null},"system":{"name":"Linux","release":"6.5.0-1016-azure"},"cpu":"x86_64","openssl_version":null,"setuptools_version":null,"rustc_version":null,"ci":true}`
* Windows GHA: `uv/0.1.21
{"installer":{"name":"uv","version":"0.1.21"},"python":"3.12.2","implementation":{"name":"CPython","version":"3.12.2"},"distro":null,"system":{"name":"Windows","release":"2022Server"},"cpu":"AMD64","openssl_version":null,"setuptools_version":null,"rustc_version":null,"ci":true}`

Distro information (such as the one pip uses `from pip._vendor import
distro` to retrieve instead of `platform` module) was not retrieved from
markers. Instead, the linux release codename/name/version uses
`sys-info` crate, adding about 50us of extra overhead on linux. The
distro osx version re-used the [mac_os version
implementation](99c992e38b/crates/platform-host/src/mac_os.rs)
from #2381 which adds about 20us of overhead on osx. I tried to use
other crates to avoid re-introducing `mac_os.rs` but most of them didn't
yield satisfactory performance (40ms-60ms~) or had the wrong values
needed (e.g. darwin version vs osx version).
I also didn't add libc retrieval or rustc retrieval as those seem to add
substantial overhead due to querying `ldd` or `rustc`. PyPy version
detection was also not added to avoid adding extra overhead to [support
PyPy for
linehaul](https://github.com/pypa/pip/blob/24.0/src/pip/_internal/network/session.py#L123).
All other behavior was kept 1-1 to match what pip's linehaul
implementation does (as of 24.0). This also aligns with what was
discussed in #1958.
## Test Plan
Added new integration test to uv-client.

## Summary
By running `get_interpreter_info.py` outside of the current working

## Summary
If a package uses Hatch's `root.uri` feature, we currently error:
```toml
dependencies = [
"black @ {root:uri}/../black_editable"
]
```
Even though we're using PEP 517 hooks to get the metadata, which
_should_ support this. The problem is that we load the full
`PyProjectToml`, which means we parse the requirements, which means we
reject what looks like a relative URL in dependencies.
Instead, we should only enforce a limited subset of `pyproject.toml`
(arguably none).
Closes https://github.com/astral-sh/uv/issues/2475.
## Summary
This PR adds limited support for PEP 440-compatible local version
testing. Our behavior is _not_ comprehensively in-line with the spec.
However, it does fix by _far_ the biggest practical limitation, and
resolves all the issues that've been raised on uv related to local
versions without introducing much complexity into the resolver, so it
feels like a good tradeoff for me.
I'll summarize the change here, but for more context, see [Andrew's
write-up](https://github.com/astral-sh/uv/issues/1855#issuecomment-1967024866)
in the linked issue.
Local version identifiers are really tricky because of asymmetry.
`==1.2.3` should allow `1.2.3+foo`, but `==1.2.3+foo` should not allow
`1.2.3`. It's very hard to map them to PubGrub, because PubGrub doesn't
think of things in terms of individual specifiers (unlike the PEP 440
spec) -- it only thinks in terms of ranges.
Right now, resolving PyTorch and friends fails, because...
- The user provides requirements like `torch==2.0.0+cu118` and
`torchvision==0.15.1+cu118`.
- We then match those exact versions.
- We then look at the requirements of `torchvision==0.15.1+cu118`, which
includes `torch==2.0.0`.
- Under PEP 440, this is fine, because `torch @ 2.0.0+cu118` should be
compatible with `torch==2.0.0`.
- In our model, though, it's not, because these are different versions.
If we change our comparison logic in various places to allow this, we
risk breaking some fundamental assumptions of PubGrub around version
continuity.
- Thus, we fail to resolve, because we can't accept both `torch @ 2.0.0`
and `torch @ 2.0.0+cu118`.
As compared to the solutions we explored in
https://github.com/astral-sh/uv/issues/1855#issuecomment-1967024866, at
a high level, this approach differs in that we lie about the
_dependencies_ of packages that rely on our local-version-using package,
rather than lying about the versions that exist, or the version we're
returning, etc.
In short:
- When users specify local versions upfront, we keep track of them. So,
above, we'd take note of `torch` and `torchvision`.
- When we convert the dependencies of a package to PubGrub ranges, we
check if the requirement matches `torch` or `torchvision`. If it's
an`==`, we check if it matches (in the above example) for
`torch==2.0.0`. If so, we _change_ the requirement to
`torch==2.0.0+cu118`. (If it's `==` some other version, we return an
incompatibility.)
In other words, we selectively override the declared dependencies by
making them _more specific_ if a compatible local version was specified
upfront.
The net effect here is that the motivating PyTorch resolutions all work.
And, in general, transitive local versions work as expected.
The thing that still _doesn't_ work is: imagine if there were _only_
local versions of `torch` available. Like, `torch @ 2.0.0` didn't exist,
but `torch @ 2.0.0+cpu` did, and `torch @ 2.0.0+gpu` did, and so on.
`pip install torch==2.0.0` would arbitrarily choose one one `2.0.0+cpu`
or `2.0.0+gpu`, and that's correct as per PEP 440 (local version
segments should be completely ignored on `torch==2.0.0`). However, uv
would fail to identify a compatible version. I'd _probably_ prefer to
fix this, although candidly I think our behavior is _ok_ in practice,
and it's never been reported as an issue.

## Summary
Right now, the middleware doesn't apply credentials that were
_originally_ sourced from a URL. This requires that we call
`with_url_encoded_auth` whenever we create a request to ensure that any
credentials that were passed in as part of an index URL (for example)
are respected.
This PR modifies `uv-auth` to instead apply those credentials in the
middleware itself. This seems preferable to me. As far as I can tell, we
can _only_ add in-URL credentials to the store ourselves (since in-URL
credentials are converted to headers by the time they reach the
middleware). And if we ever _didn't_ apply those credentials to new
URLs, it'd be a bug in the logic that precedes the middleware (i.e., us
forgetting to call `with_url_encoded_auth`).
## Test Plan
`cargo run pip install` with an authenticated index.
## Summary
This PR attempts to use a similar trick to that we added in
https://github.com/astral-sh/uv/pull/1878, but for post-releases.
In https://github.com/astral-sh/uv/pull/1878, we added a fake "minimum"
version to enable us to treat `< 1.0.0` as _excluding_ pre-releases of
1.0.0.
Today, on `main`, we accept post-releases and local versions in `>
1.0.0`. But per PEP 440, that should _exclude_ post-releases and local
versions, unless the specifier is itself a pre-release, in which case,
pre-releases are allowed (e.g., `> 1.0.0.post0` should allow `>
1.0.0.post1`).
To support this, we add a fake "maximum" version that's greater than all
the post and local releases for a given version. This leverages our last
remaining free bit in the compact representation.
`path_segments_mut` returns an `Err` for cannot-be-a-base URLs. These
won't be valid when we try to fetch them anyway, but we need to avoid a
panic.
Closes https://github.com/astral-sh/uv/issues/2460.
## Summary
It turns out that pip does _not_ validate the normalization of the
version specifier in the `.dist-info` directory. In particular, it seems
that some tools replace the `+` in a local version segment with a `_`.
Closes https://github.com/astral-sh/uv/issues/2424.
