## 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
{"ci":true,"cpu":"x86_64","distro":{"id":"jammy","libc":{"lib":"glibc","version":"2.35"},"name":"Ubuntu","version":"22.04"},"implementation":{"name":"CPython","version":"3.12.2"},"installer":{"name":"pip","version":"24.0"},"openssl_version":"OpenSSL

* Windows GHA: `pip/24.0
{"ci":true,"cpu":"AMD64","implementation":{"name":"CPython","version":"3.12.2"},"installer":{"name":"pip","version":"24.0"},"openssl_version":"OpenSSL

3.0.13 30 Jan
2024","python":"3.12.2","rustc_version":"1.76.0","system":{"name":"Darwin","release":"23.2.0"}}`
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}`
* OSX 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":"macOS","version":"14.2.1","id":null,"libc":null},"system":{"name":"Darwin","release":"23.2.0"},"cpu":"arm64","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
directory, we seem to have broken pyenv shims.
Closes https://github.com/astral-sh/uv/issues/2488.
## Test Plan
Without this change (resolving to the Homebrew Python, even though we
start with a shim):

## 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.
## Summary
The authentication middleware extracts in-URL credentials from URLs that
pass through it; however, by the time a request reaches the store, the
credentials will have already been removed, and relocated to the header.
So we were never propagating in-URL credentials.
This PR adds an explicit pass wherein we pass in-URL credentials to the
store prior to doing any work.
Closes https://github.com/astral-sh/uv/issues/2444.
## Test Plan
`cargo run pip install` against an authenticated AWS registry.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Adds basic keyring auth support for `uv` commands. Adds clone of `pip`'s
`--keyring-provider subprocess` argument (using CLI `keyring` tool).
See issue: https://github.com/astral-sh/uv/issues/1520
## Test Plan
<!-- How was it tested? -->
Hard to write full-suite unit tests due to reliance on
`process::Command` for `keyring` cli
Manually tested end-to-end in a project with GCP artifact registry using
keyring password:

## Summary
Django is actually pretty large (the wheel is 8MB, the source
distribution is 10MB). There's nothing specific to Django in any of
these tests, so this just replaces it with a much smaller dependency.
We should prune these down eventually since the scenarios cover a lot of
this -- this is just a bandaid.
## Summary
This may be required elsewhere, but all the traces in that issue are
related to persisting the temporary directory to our persistent cache,
so lets start there.
See: https://github.com/astral-sh/uv/issues/1491.
The architecture of uv does not necessarily match that of the python
interpreter (#2326). In cross compiling/testing scenarios the operating
system can also mismatch. To solve this, we move arch and os detection
to python, vendoring the relevant pypa/packaging code, preventing
mismatches between what the python interpreter was compiled for and what
uv was compiled for.
To make the scripts more manageable, they are now a directory in a
tempdir and we run them with `python -m` . I've simplified the
pypa/packaging code since we're still building the tags in rust. A
`Platform` is now instantiated by querying the python interpreter for
its platform. The pypa/packaging files are copied verbatim for easier
updates except a `lru_cache()` python 3.7 backport.
Error handling is done by a `"result": "success|error"` field that allow
passing error details to rust:
```console
$ uv venv --no-cache
× Can't use Python at `/home/konsti/projects/uv/.venv/bin/python3`
╰─▶ Unknown operation system `linux`
```
I've used the [maturin sysconfig
collection](855f6d2cb1/sysconfig)
as reference. I'm unsure how to test these changes across the wide
variety of platforms.
Fixes#2326
## Summary
Small follow up to https://github.com/astral-sh/uv/pull/2362 to check if
`SSL_CERT_FILE` is set to enable `--native-tls` functionality. This
maintains backwards compatibility with `0.1.17` and below users
leveraging only `SSL_CERT_FILE`.
Closes https://github.com/astral-sh/uv/issues/2400
## Test Plan
<!-- How was it tested? -->
Assuming `SSL_CERT_FILE` is already working via `--native-tls`, this is
simply a shortcut to enable `--native-tls` functionality implicitly
while still being able to let `rustls-native-certs` handle the loading
of `SSL_CERT_FILE` instead of ourselves.
Edit: Manually tested by setting up own self-signed CA certificate
bundle and set `SSL_CERT_FILE` to this and confirmed the loading happens
without having to specify `--native-tls`.
## Summary
Per [PEP 508](https://peps.python.org/pep-0508/), `python_version` is
just major and minor:

Right now, we're using the provided version directly, so if it's, e.g.,
`-p 3.11.8`, we'll inject the wrong marker. This was causing `pandas` to
omit `numpy` when `-p 3.11.8` was provided, since its markers look like:
```
Requires-Dist: numpy<2,>=1.22.4; python_version < "3.11"
Requires-Dist: numpy<2,>=1.23.2; python_version == "3.11"
Requires-Dist: numpy<2,>=1.26.0; python_version >= "3.12"
```
Closes https://github.com/astral-sh/uv/issues/2392.
## Summary
This PR ensures that we expand environment variables _before_ sniffing
for the URL scheme (e.g., `file://` vs. `https://` vs. something else).
Closes https://github.com/astral-sh/uv/issues/2375.
## Summary
This is a more robust fix for
https://github.com/astral-sh/uv/issues/2300.
The basic issue is:
- When we resolve, we attempt to pre-fetch the distribution metadata for
candidate packages.
- It's possible that the resolution completes _without_ those pre-fetch
responses. (In the linked issue, this was mainly because we were running
with `--no-deps`, but the pre-fetch was causing us to attempt to build a
package to get its dependencies. The resolution would then finish before
the build completed.)
- In that case, the `Index` will be marked as "waiting" for that
response -- but it'll never come through.
- If there's a subsequent call to the `Index`, to see if we should fetch
or are waiting for that response, we'll end up waiting for it forever,
since it _looks_ like it's in-flight (but isn't). (In the linked issue,
we had to build the source distribution for the install phase of `pip
install`, but `setuptools` was in this bad state from the _resolve_
phase.)
This PR modifies the resolver to ensure that we flush the stream of
requests before returning. Specifically, we now `join` rather than
`select` between the resolution and request-handling futures.
This _could_ be wasteful, since we don't _need_ those requests, but it
at least ensures that every `.wait` is followed by ` .done`. In
practice, I expect this not to have any significant effect on
performance, since we end up using the pre-fetched distributions almost
every time.
## Test Plan
I ran through the test plan from
https://github.com/astral-sh/uv/pull/2373, but ran the build 10 times
and ensured it never crashed. (I reverted
https://github.com/astral-sh/uv/pull/2373, since that _also_ fixes the
issue in the proximate case, by never fetching `setuptools` during the
resolve phase.)
I also added logging to verify that requests are being handled _after_
the resolution completes, as expected.
I also introduced an arbitrary error in `fetch` to ensure that the error
was immediately propagated.
## What
Adds a `--dry-run` flag that ejects out of the installation process
early (but after resolution) and displays only what *would have*
installed
## Closes
Closes#1244
## Out of Scope
I think it may be nice to include a `dry-run` flag for `uninstall` even
though `pip` doesn't implement this... thinking `Would uninstall X
packages: ...`

## Summary
Follow-up for
395be442fc
adds `Requires` field to pip show output.
I've aimed to make it behave exactly the same as `pip` does for now, but
there seem to be subtle issues that may require some discussion going
forward:
- Should `uv pip show` support extras? `pip` has an open issue for it,
but currently does not support https://github.com/pypa/pip/issues/4824.
- Relatedly, `Requred-by` field (not implemented in this PR) in `pip
show` currently doesn't take the extras into account transparently, i.e.
when `PySocks` has been installed as an extra for `requests[socks]`,
`pip show PySocks` doesn't have `requests` or `requests[socks]` under
`Requred-by` field. Should `uv pip show` for now just replicate `pip`'s
behavior for now for simplicity and parity or try to cover the extras
for completeness?
## Test Plan
Added a couple of tests:
1. `requests==2.31.0` has four dependencies that would be ordered
differently unless sorted. Additionally, it has two dependencies that
are optionally included for extras.
2. `pandas==2.1.3` depends on different versions of `numpy` depending on
the python version used.
## Summary
It turns out that on macOS, reading the native certificates can add
hundreds of milliseconds to client initialization. This PR makes
`--native-tls` a command-line flag, to toggle (at runtime) the choice of
the `webpki` roots or the native system roots.
You can't accomplish this kind of configuration with the `reqwest`
builder API, so instead, I pulled out the heart of that logic from the
crate
(e319263851/src/async_impl/client.rs (L498)),
and modified it to allow toggling a choice of root.
Note that there's an open PR for this in reqwest
(https://github.com/seanmonstar/reqwest/pull/1848), along with an issue
(https://github.com/seanmonstar/reqwest/issues/1843), which I may ping,
but it's been around for a while and I believe reqwest is focused on its
next major release.
Closes https://github.com/astral-sh/uv/issues/2346.
## Summary
When running under `--no-deps`, we don't need to pre-fetch, because
pre-fetching fetches the _distribution_ metadata. But with `--no-deps`,
we only need the package metadata for the top-level requirements. We
never need distribution metadata.
Incidentally, this will fix https://github.com/astral-sh/uv/issues/2300.
## Test Plan
- `cargo test`
- `./target/debug/uv pip install --verbose --no-cache-dir --no-deps
--reinstall ddtrace==2.6.2 debugpy==1.8.1 ecdsa==0.18.0
editorconfig==0.12.4 --verbose` in a Python 3.10 Docker contain
repeatedly.
## Summary
This is analogous to #669, but for cases in which the package name is a
filesystem path. In such cases, we'll fail when parsing the _package
name_, since it doesn't start with a valid character, as opposed to
failing when we go to parse the remaining version specifier.
