This is driving me a little crazy and is becoming a larger problem in
#2596 where I need to move more types (like `Upgrade` and `Reinstall`)
into this crate. Anything that's shared across our core resolver,
install, and build crates needs to be defined in this crate to avoid
cyclic dependencies. We've outgrown it being a single file with some
shared traits.
There are no behavioral changes here.
If you pass a `pyproject.toml` that use Hatch's context formatting API,
we currently fail because the dependencies aren't valid under PEP 508.
This PR makes the static metadata parsing a little more relaxed, so that
we appropriately fall back to PEP 517 there.
## Summary
Passing `pyproject.toml` or `setup.py` to `pip uninstall` is a bit
strange, since it will often require running a resolution to resolve the
dependencies (e.g., build the project), which means we also need to
accept `--index-url` and friends.
## Summary
Hatch allows for highly dynamic customization of metadata via hooks. In
such cases, Hatch
can't upload the PEP 517 contract, in that the metadata Hatch would
return by
`prepare_metadata_for_build_wheel` isn't guaranteed to match that of the
built wheel.
Hatch disables `prepare_metadata_for_build_wheel` entirely for pip.
We'll instead disable
it on our end when metadata is defined as "dynamic" in the
pyproject.toml, which should
allow us to leverage the hook in _most_ cases while still avoiding
incorrect metadata for
the remaining cases.
Closes: https://github.com/astral-sh/uv/issues/2130.
## Summary
When a user passes a `pyproject.toml` to `pip compile` (e.g., `uv pip
compile pyproject.toml`), we extract the requirements from the
`pyproject.toml` directly. However... that isn't always possible (as
seen in the linked issues). When it's _not_, we instead need to run the
PEP 517 build hooks to identify the metadata.

## Summary
`uv` was failing to install requirements defined like:
```
file://localhost/Users/crmarsh/Downloads/iniconfig-2.0.0-py3-none-any.whl
```
Closes https://github.com/astral-sh/uv/issues/2652.
While writing tests for a new flag (`--emit-marker-expression`) for `uv
pip compile`, I noticed that one of my test cases (`pendulum 3.0.0`)
was published in Dec 2023. I wanted to include this package in my
tests, but since it comes after our `EXCLUDE_NEWER` constant, it wasn't
visible to `uv`.
In this PR, I chose to resolve this by bumping `EXCLUDE_NEWER` to
`2024-03-25T00:00:00Z`. I also considered a couple other options:
* For a specific test, override and provide a custom `--exclude-newer`
flag. I felt like this would maybe be okay, but we could easily wind
up in a situation where we do this a lot and have a bunch of different
`--exclude-newer` flags in our tests. I'm not sure if this is a huge
problem in practice. Maybe it's fine.
* Find another package (or invent one) with a similarly interesting
configuration. It seemed easier to just bump `EXCLUDE_NEWER`.
The way I did this was to run `cargo insta test` after bumping
`EXCLUDE_NEWER`.
I then reviewed the snapshot diffs, and if they looked reasonable, I
accepted them.
There was only one case where I changed the test to preserve what I
thought it
was trying to test. That's isolated in its own commit.
With https://github.com/pubgrub-rs/pubgrub/pull/190, pubgrub attaches
all types to a dependency provider to reduce the number of generics. We
need a dummy dependency provider now to emulate this. On the plus side,
pep440_rs drops its pubgrub dependency.
This test was introduced in 42973cd9cb. It
looks like it compares some values against some platform specific code
that attempts to find the OS version. But the comparisons made some
assumptions about what kind of data is available. In this commit, we try
to make the test a little more flexible on Linux by not assuming that
`Option` values are `Some`.
## Summary
I don't see a great reason to allow this, and it adds a lot of
complexity, so `pyproject.toml` files are now limited to `pip compile`
and `pip install -r` -- they can't be passed as `-c` or `--override`.
## Summary
Closes Issue:
- https://github.com/astral-sh/uv/issues/2626
## Test Plan
```
cargo run -- pip install -r dev-requirements.txt -r requirements.txt
```
where both requirements files have same `--index-url`
We put a `.gitignore` with `*` at the top of our cache. When maturin was
building a source distribution inside the cache, it would walk up the
tree to find a gitignore, see that and ignore all python files. We now
add an (empty) `.git` directory one directory below, in the root of
built-wheels cache. This prevents ignore walking further up (it marks
the top level a git repository).
Deptry (from #2490) is a mid sized rust package with additional python
packages, so instead of using it in the test i've replaced it with a
small (44KB total) reproducer that uses cffi for faster building, the
entire test taking <2s on my machine.
Fixes#2490
## Summary
Ensures that (e.g.) installs from conda-forge, Homebrew, and other
distributions don't expose `uv self update` at all.
We'll still show `uv self update` for `pip install uv`, but it will fail
with a good error. Removing the `uv self update` from `pip`-installed
`uv` is more complicated, since we'd need to build separately for the
installer vs. for PyPI.
Closes#2588.
## Summary
This PR enables the source distribution database to be used with unnamed
requirements (i.e., URLs without a package name). The (significant)
upside here is that we can now use PEP 517 hooks to resolve unnamed
requirement metadata _and_ reuse any computation in the cache.
The changes to `crates/uv-distribution/src/source/mod.rs` are quite
extensive, but mostly mechanical. The core idea is that we introduce a
new `BuildableSource` abstraction, which can either be a distribution,
or an unnamed URL:
```rust
/// A reference to a source that can be built into a built distribution.
///
/// This can either be a distribution (e.g., a package on a registry) or a direct URL.
///
/// Distributions can _also_ point to URLs in lieu of a registry; however, the primary distinction
/// here is that a distribution will always include a package name, while a URL will not.
#[derive(Debug, Clone, Copy)]
pub enum BuildableSource<'a> {
Dist(&'a SourceDist),
Url(SourceUrl<'a>),
}
```
All the methods on the source distribution database now accept
`BuildableSource`. `BuildableSource` has a `name()` method, but it
returns `Option<&PackageName>`, and everything is required to work with
and without a package name.
The main drawback of this approach (which isn't a terrible one) is that
we can no longer include the package name in the cache. (We do continue
to use the package name for registry-based distributions, since those
always have a name.). The package name was included in the cache route
for two reasons: (1) it's nice for debugging; and (2) we use it to power
`uv cache clean flask`, to identify the entries that are relevant for
Flask.
To solve this, I changed the `uv cache clean` code to look one level
deeper. So, when we want to determine whether to remove the cache entry
for a given URL, we now look into the directory to see if there are any
wheels that match the package name. This isn't as nice, but it does work
(and we have test coverage for it -- all passing).
I also considered removing the package name from the cache routes for
non-registry _wheels_, for consistency... But, it would require a cache
bump, and it didn't feel important enough to merit that.
## Summary
Detects unused cache entries, which can come in a few forms:
1. Directories that are out-dated via our versioning scheme.
2. Old source distribution builds (i.e., we have a more recent version).
3. Old wheels (stored in `archive-v0`, but not symlinked-to from
anywhere in the cache).
Closes https://github.com/astral-sh/puffin/issues/1059.
Closes#2566
We were storing the username e.g. `charlie@astral.sh` as a
percent-encoded string `charlie%40astral.sh` which resulted in different
headers and broke JFrog's artifactory which apparently does not decode
usernames.
Tested with a JFrog artifactory and AWS CodeArtifact although it is
worth noting that AWS does _not_ have a username with an `@` — it'd be
nice to test another artifactory with percent-encoded characters in the
username and/or password.
## Summary
In `pip uninstall`, we shouldn't need to resolve unnamed requirements,
since we already index packages in `site-packages` by their URL.
This also changes `uninstall` to ignore editables, which matches pip's
behavior.
Part of: https://github.com/astral-sh/uv/issues/313.
## Test Plan
Run `cargo run pip install ./scripts/editable-installs/black_editable`,
followed by each of the following:
- `cargo run pip uninstall ./scripts/editable-installs/black_editable`
- `cargo run pip uninstall black`
- `cargo run pip uninstall ./scripts/editable-installs/black_editable
black`
## Summary
This PR ensures that if a package is already satisfied by the current
environment, we don't bother resolving the named requirement.
Part of: https://github.com/astral-sh/uv/issues/313.
## Test Plan
- `cargo run pip install ./scripts/editable-installs/black_editable`
- `cargo run pip install black --verbose`
## Summary
For example: `cargo run pip install .`
The strategy taken here is to attempt to extract the package name from
the distribution without executing the PEP 517 build steps. We could
choose to do that in the future if this proves lacking, but it adds
complexity.
Part of: https://github.com/astral-sh/uv/issues/313.
## Summary
This PR enables `uv pip install` to accept unnamed requirements, as long
as the requirement ends with the wheel or source distribution archive
name. For example: `cargo run pip install
~/Downloads/anyio-4.3.0.tar.gz`.
In subsequent PRs, I'll expand the scope of supported archives and
patterns.
Part of: https://github.com/astral-sh/uv/issues/313.
## Summary
First piece of https://github.com/astral-sh/uv/issues/313. In order to
support unnamed requirements, we need to be able to parse them in
`requirements-txt`, which in turn means that we need to introduce a new
type that's distinct from `pep508::Requirement`, given that these
_aren't_ PEP 508-compatible requirements.
Part of: https://github.com/astral-sh/uv/issues/313.
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 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`.

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

## 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

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:

Here's how uv results look like (sorry for the keys not having the same
order):

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
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
Resolves https://github.com/astral-sh/uv/issues/2391
<!-- What's the purpose of the change? What does it do, and why? -->

## 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.
Inspired by https://github.com/astral-sh/uv/issues/2356.
## Summary
Add a new env variable `UV_SYSTEM` as alias for the cli argument
`--system`.
Use cases:
- No need to specify on each uv call inside the docker container the
`--system` flag
- It allows installing and configuring uv in a base container and in the
child containers nobody needs to know if you need the `--system` cli
flag
- The Home Assistant development env can be set up via devcontainer or a
venv. Both use some common scripts. Instead of adding duplicate or
special code to identify the dev container to set the `--system` flag,
it would be nicer to set it via an env variable.
I'm unfamiliar with Rust and tried to add the support by looking at the
code.
## Test Plan
I did test it manually
`UV_SYSTEM_PYTHON=true uv pip install requests`
## Summary
It turns out that when we iterate over the incompatibilities of a
package, PubGrub will _also_ show us the inverse dependencies. I suspect
this was rare, because we have a version check at the bottom... So, this
specifically required that you had some dependency that didn't end up
appearing in the output resolution, but that matched the version
constraints of the package you care about.
In this case, `langchain-community` depends on `langchain-core`. So we
were seeing an incompatibility like:
```rust
FromDependencyOf(Package(PackageName("langchain-community"), None, None), Range { segments: [(Included("0.0.10"), Included("0.0.10")), (Included("0.0.11"), Included("0.0.11"))] }, Package(PackageName("langchain-core"), None, None), Range { segments: [(Included("0.1.8"), Excluded("0.2"))] })
```
Where we were iterating over `langchain-core`, and looking for version
`0.0.11`... which happens to match `langchain-community`.
(`langchain-community was omitted from the resolution; hence, it didn't
exist in the map.)
Closes https://github.com/astral-sh/uv/issues/2358.
## Summary
We now initialize an HTTP client in advance for remote requirements
files. It turns out this adds a significant overhead, even for
operations like auditing the environment (at least on macOS).
This PR makes initialization lazy. After a lot of evaluation, I took the
easiest route, which is: we just pass in `Connectivity`, and then use
the default HTTP client. So we won't respect netrc files and anything
else that we get from our registry client. If we want to keep using the
registry client, we _can_, it's just way more ceremony to pass down a
closure.
See: https://github.com/astral-sh/uv/issues/2346.
## Test Plan
- Verified that `cargo run pip compile
https://raw.githubusercontent.com/ansible/ansible/f1ded0f41759235eb15a7d13dbc3c95dce5d5acd/requirements.txt`
completed without error.
- Verified that `cargo run pip compile
https://raw.githubusercontent.com/ansible/ansible/f1ded0f41759235eb15a7d13dbc3c95dce5d5acd/requirements.txt
--offline` failed with an error.
- Verified that `./target/release/uv pip install requests` completed in
0-2ms, rather than hundreds.
## Summary
In #2000, I shipped a regression whereby we stopped writing relative
paths for scripts within `data` directories. The net effect here is that
we aren't _uninstalling_ binaries in all cases. (This does _not_ apply
to entrypoints, only scripts in `data` directories.)
Closes https://github.com/astral-sh/uv/issues/2330.
## Test Plan
Most Python packages ship entrypoints, not binaries, so I don't know how
to test this cheaply. But I did test it locally by verifying that `uv`
is now removed from the `bin` directory after an uninstall.
## Summary
Some zip files can't be streamed; in particular, `rs-async-zip` doesn't
support data descriptors right now (though it may in the future). This
PR adds a fallback path for such zips that downloads the entire zip file
to disk, then unzips it from disk (which gives us `Seek`).
Closes https://github.com/astral-sh/uv/issues/2216.
## Test Plan
`cargo run pip install --extra-index-url https://buf.build/gen/python
hashb_foxglove_protocolbuffers_python==25.3.0.1.20240226043130+465630478360
--force-reinstall -n`
## Summary
The netrc middleware we added in
https://github.com/astral-sh/uv/pull/2241 has a slight problem. If you
include credentials in your index URL, _and_ in the netrc file, the
crate blindly adds the netrc credentials as a header. And given the
`ReqwestBuilder` API, this means you end up with _two_ `Authorization`
headers, which always leads to an invalid request, though the exact
failure can take different forms.
This PR removes the middleware crate in favor of our own middleware.
Instead of using the `RequestInitialiser` API, we have to use the
`Middleware` API, so that we can remove the header on the request
itself.
Closes https://github.com/astral-sh/uv/issues/2323.
## Test Plan
- Verified that running against a private index with credentials in the
URL (but no netrc file) worked without error.
- Verified that running against a private index with credentials in the
netrc file (but not the URL) worked without error.
- Verified that running against a private index with a mix of
credentials in both _also_ worked without error.
## Summary
We write this a few lines down with a value passed in by the caller. I
suspect I missed that this was already here (with a less accurate value)
when adding `INSTALLER`.
`packaging==24.0` came out which broke this test. It has to run without
`--exclude-newer` since it's testing an index that doesn't support it.
Instead, though, we can just disable dependencies, since the test still
exercises the same logic.
Preparing for #2058, i found it hard to follow where which discovery
function gets called. I moved all the discovery functions to a
`find_python` module (some exposed through `PythonEnvironment`) and
documented which subcommand uses which python discovery strategy.
No functional changes.

`install_extra_index_url_has_priority` started failing because
`packaging` had a new release. I'm not sure if this preserves the index
order check as intended, but it does unblock CI.
## Summary
No behavioral changes; just taking code that's duplicated between two
branches in `distribution_database.rs` and pulling it into its own
method.
## Summary
Addressing the extremely slow performance detailed in
https://github.com/astral-sh/uv/issues/2220. There are two changes to
increase download performance:
1. setting `accept-encoding: identity`, in the spirit of
https://github.com/pypa/pip/pull/1688
2. increasing buffer from 8KiB to 128KiB.
### 1. accept-encoding: identity
I think this related `pip` PR has a good explanation of what's going on:
https://github.com/pypa/pip/pull/1688
```
# We use Accept-Encoding: identity here because requests
# defaults to accepting compressed responses. This breaks in
# a variety of ways depending on how the server is configured.
# - Some servers will notice that the file isn't a compressible
# file and will leave the file alone and with an empty
# Content-Encoding
# - Some servers will notice that the file is already
# compressed and will leave the file alone and will add a
# Content-Encoding: gzip header
# - Some servers won't notice anything at all and will take
# a file that's already been compressed and compress it again
# and set the Content-Encoding: gzip header
```
The `files.pythonhosted.org` server is the 1st kind. Example debug log I
added in `uv` when installing against PyPI:
<img width="1459" alt="image"
src="https://github.com/astral-sh/uv/assets/12058921/ef10d758-46aa-4c8e-9dba-47f33437401b">
(there is no `content-encoding` header in this response, the `whl`
hasn't been compressed, and there is a content-length header)
Our internal mirror is the third case. It does seem sensible that our
mirror should be modified to act like the 1st kind. But `uv` should
handle all three cases like `pip` does.
### 2. buffer increase
In https://github.com/astral-sh/uv/issues/2220 I observed that `pip`'s
downloading was causing up-to 128KiB flushes in our mirror.
After fix 1, `uv` was still only causing up-to 8KiB flushes, and was
slower to download than `pip`. Increasing this buffer from the default
8KiB led to a download performance improvement against our mirror and
the expected observed 128KiB flushes.
## Test Plan
Ran benchmarking as instructed by @charliermarsh
<img width="1447" alt="image"
src="https://github.com/astral-sh/uv/assets/12058921/840d9c8d-4b98-4bfa-89f3-073a2dec1f23">
No performance improvement or regression.
## Summary
In #1813, we were failing to install `scikit-image==0.19.3` from source
in Python 3.11. Confusingly, though, the trace showed that the build
command exited with status 0...
The issue is that we get results from the PEP 517 hooks by reading from
`stdout` -- that is, we `print` at the end of the script, and parse the
printed output on the other side.
It turns out that for `scikit-image`, in this case, there was output
_after_ the wheel filename:
```

```
We need the `scikit_image-0.19.3-cp311-cp311-macosx_14_0_arm64.whl`
line, but we were failing to find it due to all the extra output at the
end (presumedly, some kind of `atexit` logging).
This PR modifies the hooks to instead write their results to files that
are passed in by the parent. On the other end, we then read the results
back from disk. This makes it much more robust to "other" output in the
script.
Closes https://github.com/astral-sh/uv/issues/1813.
## Test Plan
Ran `cargo run pip install scikit-image==0.19.3 --reinstall
--no-cache-dir` on Python 3.11.
## Summary
It turns out that setuptools includes a shim to patch distutils. I'll
admit that I don't fully understand why or how it's different, but this
is the trick `pip` uses to ensure that it gets the "original" distutils.
We actually use distutils in two places: once for the system Python
scheme, and once for virtual environments. In virtualenv, they _do_ use
the patched distutils, so this could deviate in ways I don't understand.
Closes#2302.
Extends the "compatibility" types introduced in #1293 to apply to source
distributions as well as wheels.
- We now track the most-relevant incompatible source distribution
- Exclude newer, Python requirements, and yanked versions are all
tracked as incompatibilities in the new model (this lets us remove
`DistMetadata`!)
Since Python 3.7, deterministic pycs are possible (see [PEP
552](https://peps.python.org/pep-0552/))

## Summary
PyPI now supports Metadata 2.2, which means distributions with Metadata
2.2-compliant metadata will start to appear. The upside is that if a
source distribution includes a `PKG-INFO` file with (1) a metadata
version of 2.2 or greater, and (2) no dynamic fields (at least, of the
fields we rely on), we can read the metadata from the `PKG-INFO` file
directly rather than running _any_ of the PEP 517 build hooks.
Closes https://github.com/astral-sh/uv/issues/2009.
This PR tweaks uv to support reading `requirements.txt` regardless of
whether it is encoded as UTF-8 or UTF-16. This is particularly relevant
on Windows where `uv pip freeze > requirements.txt` will likely write a
UTF-16 encoded `requirements.txt` file.
There is some discussion on #1666 where it's suggested that perhaps
we should explicitly not support this. I didn't see that until I
had already put this PR together, but even so, I think it's worth
considering this. UTF-16 is predominant on Windows. It is very easy
to produce a UTF-16 encoded file. Moreover, there is an easy and well
specified way to recognize and transcode UTF-16 encoded data to UTF-8.
I think the downside of this is that it could encourage the use UTF-16
encoded `requirements.txt` files *in addition* to UTF-8 encoded
files, and it would probably be nice to converge and standardize on
one encoding. One possible alternative to this PR is that we provide
a better error message. Another alternative is to ensure that a
`-o/--output` flag exists for all commands (neither `uv pip freeze` nor
`pip freeze` have such a flag) so that users can always write output
to a file without relying on their environment's piping behavior.
(Although this last alternative seems a little sad to me.)
It's also worth noting the [PEP-0508] doesn't seem to mention file
encoding at all. So I think from a "do the standards allow this"
perspective, this change is OK.
Finally, `pip` itself seems to work with UTF-16 encoded
`requirements.txt` files.
I think I personally overall lean towards supporting UTF-16 for
`requirements.txt` files. In part because I think it smoothes out the
UX a little bit, in part because there is no obvious specification
(that I'm aware of) that mandates that these files are UTF-8, and
finally in part because `pip` supports it too.
Fixes#1666, Fixes#2276

## Summary
refactor pip_list function to trim end of joined elements
fixed: https://github.com/astral-sh/uv/issues/2296
<!-- How was it tested? -->
## Summary
If a user provides a source distribution via a direct path, it can
either be an archive (like a `.tar.gz` or `.zip` file) or a directory.
If the former, we need to extract (e.g., unzip) the contents at some
point. Previously, this extraction was in `uv-build`; this PR lifts it
up to the distribution database.
The first benefit here is that various methods that take the
distribution are now simpler, as they can assume a directory.
The second benefit is that we no longer extract _multiple times_ when
working with a source distribution. (Previously, if we tried to get the
metadata, then fell back and built the wheel, we'd extract the wheel
_twice_.)
## Summary
This PR removes the URL conflict errors when the output of a `uv pip
compile` is used as a constraint to a subsequent `uv pip compile`.
If you run `uv pip compile`, the output file will contain your Git
dependencies, but pinned to a specific commit, like:
```
git+https://github.com/pallets/werkzeug@32e69512134c2f8183c6438b2b2e13fd24e9d19f
```
If you then use the output as a constraint to a subsequent resolution
(e.g., perhaps you require
`git+https://github.com/pallets/werkzeug@main`), we currently fail. I
think this is a reasonable workflow to support when all of these
requirements are coming from _your own_ dependencies. So we now assume
when resolving that the former is a more precise variant of the latter.
Closes https://github.com/astral-sh/uv/issues/1903.
Closes https://github.com/astral-sh/uv/issues/2266.
## Test Plan
`cargo test`
## Summary
This PR enables use of the Windows Store Pythons even with `py` is not
installed. Specifically, we need to ensure that the `python.exe` and
`python3.exe` executables installed into the
`C:\Users\crmar\AppData\Local\Microsoft\WindowsApp` directory _are_ used
when they're not "App execution aliases" (which merely open the Windows
Store, to help you install Python).
When `py` is installed, this isn't strictly necessary, since the
"resolved" executables are discovered via `py`. These look like
`C:\Users\crmar\AppData\Local\Microsoft\WindowsApps\PythonSoftwareFoundation.Python.3.11_qbs5n2kfra8p0\python.exe`.
Closes https://github.com/astral-sh/uv/issues/2264.
## Test Plan
- Removed all Python installations from my Windows machine.
- Uninstalled `py`.
- Enabled "App execution aliases".
- Verified that for both `cargo run venv --python python.exe` and `cargo
run venv --python python3.exe`, `uv` exited with a failure that no
Python could be found.
- Installed Python 3.10 via the Windows Store.
- Verified that the above commands succeeded without error.
- Verified that `cargo run venv --python python3.10.exe` _also_
succeeded.
- Now that `packse` is being published to PyPI we can install it from
there.
- Tweaks the tooling around scenario updates to manage a temporary
virtual environment for you.
- Makes use of a new index URL
- Includes local version segment scenarios (supersedes
https://github.com/astral-sh/uv/pull/2022)
Sometimes, the first time we read from the stdout of the bytecode
compiler python subprocess, we get an empty string back (no newline). If
we try to write to stdin, it will often be a broken pipe (#2245). After
we got an empty string the first time, we will get the same empty string
if we read a line again.
The details of this behavior are mysterious to me, but it seems that it
can be identified by the first empty string. We check by inserting
starting with a `Ready` message on the Python side. When we encounter
the broken state, we discard the interpreter and try again.
We have to introduce a third timeout check for the interpreter launch
itself.
Minimized test script:
```bash
#!/usr/bin/env bash
set -euo pipefail
while true; do
date --iso-8601=seconds # Progress indicator
rm -rf testenv
target/profiling/uv venv testenv -q --python 3.12
VIRTUAL_ENV=$PWD/testenv target/profiling/uv pip install -q --compile wheel==0.42.0
done
```
Run as
```
cargo build --profile profiling && bash compile_bug.sh
```
Fixes#2245
## Summary
In #2102, I did some refactor, and changed a method to return the Python
executable path rather than the parent directory path. But I missed this
one codepath for Conda on Windows.
Closes https://github.com/astral-sh/uv/issues/2269.
## Test Plan
- Installed micromamba on my Windows machine.
- Reproduced the failure in the linked issue.
- Verified that `python.exe` exists at `${CONDA_PREFIX}\python.exe`.
- Ran with this change; installed successfully.
## Summary
In the list of tags produced by `Tags::from_env`, higher-priority tags
are expected to come earlier in the list. Right now, though, we push
tags like `py38` before `py312`. So if you run `cargo run pip install
multiprocess -n --reinstall --verbose` on Python 3.12, you get the
`py38` wheel rather than the `py32` wheel.
Closes https://github.com/astral-sh/uv/issues/2261.
## Summary
This PR adds support for pip's `--no-build-isolation`. When enabled,
build requirements won't be installed during PEP 517-style builds, but
the source environment _will_ be used when executing the build steps
themselves.
Closes https://github.com/astral-sh/uv/issues/1715.
Fix parsing `pytest;'4.0'>=python_version`, where previously the
operator and the variable were incorrectly tokenized as one invalid
operator.
Fixes#2247
Running the pep508_rs tests was failing due to uv-fs depending on
`fs_err::tokio` even when not selected. But the function that used it is
unused anyway, so i removed it.
## Summary
It turns out that by keeping the `RECORD` file open, older versions of
Windows mark it for deletion, but don't allow it to be deleted until
it's closed. As such, we end up leaving the `.dist-info` directory
around, since it appears non-empty; but once the program terminates, we
_do_ delete `RECORD`, leaving it empty. This then creates the impression
that a package exists where it does not.
Closes https://github.com/astral-sh/uv/issues/2074.
## Summary
If we fallback to streaming the wheel (because the registry doesn't
support range requests), we currently don't cache the metadata at all.
This PR fixes that, ensuring that we cache based on the same HTTP
policies, etc.
## Summary
We're seeing reports that Sonatype Nexus isn't working with cached data.
Users are reporting 304 responses that show "Found modified response..."
path in the logs. I can't reproduce this on latest Sonatype Nexus, but
my best guess is that there's a 304 response that is failing our
validators, and we try to use that as if it's a "complete" response?
Closes https://github.com/astral-sh/uv/issues/1754.
## Summary
Add netrc support to the uv-client.
closes#1405
## Test Plan
I've added a corresponding test case to validate the correct header.
Furthermore a tested it against a real world private repository.
## Summary
Per the
[`EXTERNALLY-MANAGED`](https://packaging.python.org/en/latest/specifications/externally-managed-environments/)
spec, installers SHOULD add a `--break-system-packages` flag to allow
users to override the package manager warnings raised by
`EXTERNALLY-MANAGED`. This PR adds the flag to comply with the spec, and
enable system Python installs on newer versions of certain
distributions.
While this flag feels kind of bad, it's not necessarily a change in
behavior. We _already_ allow installing into these system distributions
-- it's just that `EXTERNALLY-MANAGED` doesn't exist for distributions
that were packaged prior to the spec, so we don't run into this problem.
Closes https://github.com/astral-sh/uv/issues/2234.
## Summary
This is no longer necessary as `AsyncHttpRangeReader` now accepts
`ClientWithMiddleware` -- which is good, because it means all relevant
middleware will be enforced (like offline, or `.netrc` in the future).
## Summary
Fix computing replacements pattern for pip_list tests to count
characters in the original directory string rather than the
regex::escape'd string. The latter yields incorrect results if the
workspace path contains characters such as `-` or `.`.
Fixes#2232
## Test Plan
`cargo test --test pip_list` in a directory named `uv-test` to provoke
the bug.
## Summary
Allow using http(s) urls for constraints and requirements files handed
to the CLI, by handling paths starting with `http://` or `https://`
differently. This allows commands for such as: `uv pip install -c
https://raw.githubusercontent.com/apache/airflow/constraints-2.8.1/constraints-3.8.txt
requests`.
closes#1332
## Test Plan
Testing install using a `constraints.txt` file hosted on github in the
airflow repository:
fbdc2eba8e/crates/uv/tests/pip_install.rs (L1440-L1484)
## Advice Needed
- filesystem/http dispatch is implemented at a relatively low level (at
`crates/uv-fs/src/lib.rs#read_to_string`). Should I change some naming
here so it is obvious that the function is able to dispatch?
- I kept the CLI argument for -c and -r as a PathBuf, even though now it
is technically either a path or a url. We could either keep this as is
for now, or implement a new enum for this case? The enum could then
handle dispatch to files/http.
- Using another abstraction layer like
https://docs.rs/object_store/latest/object_store/ for the
files/urls/[s3] could work as well, though I ran into a bug during
testing which I couldn't debug
## Summary
Follow up from discussion in https://github.com/astral-sh/uv/pull/2223
Detect CMD.exe by checking if `PROMPT` env var is set on windows,
otherwise assume it's PowerShell.
Note, this will not work if user modifies their system env vars to
include `PROMPT` by default or if they launch nested PowerShell from
Command Prompt (e.g. `Developer PowerShell for VS 2022`).
## Test Plan
Only tested locally, although we try to add some CI tests that
specifically use CMD.exe

## Summary
Implementation for https://github.com/astral-sh/uv/issues/1594
The output will contain only the name, version and location of the
packages for now but it should be extendable to include other
information in the future.
Quite inexperienced with Rust, so please forgive me if there are things
that obviously don't make sense 😭
## Test Plan
Added a bunch of unit tests. The exit code behavior matches `pip`'s
behavior:
- When the package is found -> exit code 0
- When the package isn't found -> exit code 1
- When one package is found but another isn't -> exit code 0
Implements `pip list --format=freeze` and `pip list --format=json`
Closes https://github.com/astral-sh/uv/issues/1970
## Test Plan
Extended existing `pip list` tests to match output.
Need to look at escaping in the Windows test 🪟
## Summary
`pip` uses `sysconfig` for Python 3.10 and later by default; however, it
falls back to `distutils` for earlier Python versions, and distros can
actually tell `pip` to continue falling back to `distutils` via the
`_PIP_USE_SYSCONFIG` variable.
By _always_ using `sysconfig`, we're doing the wrong then when
installing into some system Pythons, e.g., on Debian prior to Python
3.10.
This PR modifies our logic to mirror `pip` exactly, which is what's been
recommended to me as the right thing to do.
Closes https://github.com/astral-sh/uv/issues/2113.
## Test Plan
Most notably, the new Debian tests pass here (which fail on main:
https://github.com/astral-sh/uv/pull/2144).
I also added Pyston as a second stress-test.
## Summary
This PR migrates our virtualenv creation from a setup that assumes prior
knowledge of the correct paths, to a technique borrowed from
`virtualenv` whereby we use `sysconfig` and `distutils` to determine the
paths. The general trick is to grab the expected paths with `sysconfig`,
then make them all relative, then make them absolute for a given
directory.
Closes#2095.
Closes#2153.
## Summary
This makes `--python python3` and `--python 3.10` more consistent on
Windows.
Closes https://github.com/astral-sh/uv/issues/2213.
## Test Plan
Ran `cargo run venv --python python3.12` with the Windows Store Python.
## Summary
We have logic in `python_query.rs` to filter out Windows Store shims
when you use invocations like `-p 3.10`, but not `--python python3`,
which is uncommon but allowed on Windows.
Closes#2211.
## Summary
Our Windows shim detection wasn't catching shims like `python3.12.exe`.
Closes#2208.
## Test Plan
Installed Python 3.12 via the Windows Store; verified that `cargo run
venv --python 3.12` failed before but passes after this change.
## Summary
When determining "direct" dependencies, we need to ensure that we
respect markers. In the linked issue, the user had an optional
dependency like:
```toml
[project.optional-dependencies]
dev = [
"setuptools>=64",
"setuptools_scm>=8"
]
```
By not respecting markers, we tried to resolve `setuptools` to the
lowest-available version. However, since `setuptools>=64` _isn't_
enabled (since it's optional), we won't respect _that_ constraint.
To be consistent, we need to omit optional dependencies just as we will
at resolution time.
Closes https://github.com/astral-sh/uv/issues/2203.
## Test Plan
`cargo test`
Follow-up to #2086: Don't use timeouts for the entire workers, but only
for the section that's about communicating with the (potentially broken)
`python` subprocess. I've also raised the timeout to 60s.
Add a `--compile` option to `pip install` and `pip sync`.
I chose to implement this as a separate pass over the entire venv. If we
wanted to compile during installation, we'd have to make sure that
writing is exclusive, to avoid concurrent processes writing broken
`.pyc` files. Additionally, this ensures that the entire site-packages
are bytecode compiled, even if there are packages that aren't from this
`uv` invocation. The disadvantage is that we do not update RECORD and
rely on this comment from [PEP 491](https://peps.python.org/pep-0491/):
> Uninstallers should be smart enough to remove .pyc even if it is not
mentioned in RECORD.
If this is a problem we can change it to run during installation and
write RECORD entries.
Internally, this is implemented as an async work-stealing subprocess
worker pool. The producer is a directory traversal over site-packages,
sending each `.py` file to a bounded async FIFO queue/channel. Each
worker has a long-running python process. It pops the queue to get a
single path (or exists if the channel is closed), then sends it to
stdin, waits until it's informed that the compilation is done through a
line on stdout, and repeat. This is fast, e.g. installing `jupyter
plotly` on Python 3.12 it processes 15876 files in 319ms with 32 threads
(vs. 3.8s with a single core). The python processes internally calls
`compileall.compile_file`, the same as pip.
Like pip, we ignore and silence all compilation errors
(https://github.com/astral-sh/uv/issues/1559). There is a 10s timeout to
handle the case when the workers got stuck. For the reviewers, please
check if i missed any spots where we could deadlock, this is the hardest
part of this PR.
I've added `uv-dev compile <dir>` and `uv-dev clear-compile <dir>`
commands, mainly for my own benchmarking. I don't want to expose them in
`uv`, they almost certainly not the correct workflow and we don't want
to support them.
Fixes#1788Closes#1559Closes#1928
## Summary
We have at least one reported case of this happening. It's preferable
IMO to move on rather than fail hard despite sub-pbar registry behavior.
Closes https://github.com/astral-sh/uv/issues/2099.
