## Summary
The prior implementation only looks for dependencies which are sorted by
name then specifier.
I knew uv was meant to preserve sorted dependencies, but it never seemed
to work for me.
I've always used the "sort lines" feature of PyCharm/Sublime to sort
these lists, and I guess I'm not the only one. In such a case,
`flask-wtf>=1.2.1` is sorted before `flask>=3.0.2`.
After digging into the code I realised what was happening, hence this
merge request.
Maybe there's a tool I'm not aware of that people are using to sort
dependencies "properly", or are doing it by hand, but I think this is
worth supporting.

## Test Plan
`cargo test`
e.g., these are misleading cruft in the error message at
https://github.com/astral-sh/uv/pull/12168#discussion_r2078204601
```
❯ uv python find /foo/bar
error: No interpreter found for path `/foo/bar` in virtual environments, managed installations, or search path
❯ cargo run -q -- python find /foo/bar
error: No interpreter found at path `/foo/bar`
```
When removing a Python interpreter underneath an existing venv, uv
currently shows a not found error:
```
error: Failed to inspect Python interpreter from active virtual environment at `.venv/bin/python3`
Caused by: Python interpreter not found at `/home/konsti/projects/uv/.venv/bin/python3`
```
This is unintuitive, as the file for the Python interpreter does exist,
it is a broken symlink that needs to be replaced with `uv venv`.
I've been encountering those occasionally, and I expect users that
switch between versions a lot will, too, especially when they also use
pyenv or a similar Python manager.
The new error hints at this solution:
```
error: Failed to inspect Python interpreter from active virtual environment at `.venv/bin/python3`
Caused by: Broken symlink at `.venv/bin/python3`, was the underlying Python interpreter removed?
hint: To recreate the virtual environment, run `uv venv`
```
PEP 639 does not allow any characters that aren't in either their
limited glob syntax or the alphanumeric Unicode characters. This means
there's no way to express a glob such as `**/@test` for the excludes.
We extend the glob syntax from PEP 639 by introducing backslash escapes,
which can escape all characters but path separators (forward and
backwards slashes) to be parsed verbatim.
This means we have two glob parsers: The strict PEP 639 parser for
`project.license-files`, and our extended parser for `tool.uv`, with a
slight difference if you need to use special characters, to both adhere
to PEP 639 and to support cases such as #13280.
Fixes#13280
We have test coverage for this elsewhere, but managed Python versions
are a distinct case because we know the _full_ version before querying
the interpreter (whereas, when we find them on the `PATH`, we usually
only know `X.y` from the file name).
This pre-filter logic now matches our subsequent logic at
060be9cef1/crates/uv-python/src/discovery.rs (L2146-L2149)060be9cef1
shows the snapshot change.
## Summary
Add a `--show-extras` argument to the `uv tool list` cli, to show which
extra dependencies were installed with the tool.
i.e.
```bash
$ uv tool install fastapi --with requests --with typer==0.14
```
```bash
$ uv tool list --show-extras
fastapi v0.115.12 [extras: requests, typer==0.14]
- fastapi
```
## Test Plan
Added a new test function based on the others in the same file, with the
other arguments tested with the new argument as well.
The goal of this PR is to support reproducible builds and best-effort
platform-independent builds. Previously, while the build backend would
build the same source dist and wheel on the same machine, they would
look different across different operating systems. This PR fixes the
platform-dependent walk dir order by sorting and removes
platform-specific permissions from the source dist that had caused those
differences.
The reproducibility goal does not extend to platform-dependent
filesystem features, such as permissions and links, especially in
interaction with Git. Since most users share code across platforms
through Git, we're focusing on cross-platform behavior under Git. One of
those caveats is intentional: If a file, such as a bash script, has an
executable bit, we preserve it. This means that E.g. builds of Git
checkout of a repository with an executable shell script in the sources
will have different archives on Unix and Windows. Another relevant case
are symlinks: By default, Git on Windows replaces symlinks with a file
that contains the path to the target file
(https://stackoverflow.com/q/5917249/3549270). (This example comes from
Cargo, where it means that the package archive is different on Windows
when symlinking license from the repository root to a workspace package)

## Summary
This adds GraalPy download metadata so that `uv python install graalpy`
works. See https://github.com/astral-sh/uv/issues/13114
## Test Plan
The existing integration test was changed to test this functionality.
In #13302, there was an IO error without context. This error seems to be
caused by a symlink error. Switching as symlinking to `fs_err` ensures
these errors will carry context in the future.
## Summary
We now show a user-visible warning if we're using a "stale" virtual
environment due to `--no-sync`. I'd also be fine erroring here.
Closes https://github.com/astral-sh/uv/issues/13235.
Add configuration documentation for the build backend and make it the
preview default.
The build backend should generally work with default configuration
unless you want specific features such as flat layout or module
renaming, there is only a dedicated configuration, but no concept or
guide page for the build backend. Once the build backend is stable, we
can update the guide documentation to explain that uv defaults to its
own build backend, but other build backends are also supported.
The uv build backend becomes the default in preview, giving it more
exposure from users and preparing it to make it the default proper. The
current documentation retains warnings that the build backend is in
preview.

## Summary
If a script has some requirements, and you provide `--with`, we
currently ignore any constraints from those requirements. We might want
to treat them as hard constraints in the future. For now, though, we
just treat them as preferences -- so we _prefer_ those versions, but
don't require them to match and still run the `--with` resolution in
isolation.

## Summary
Part of https://github.com/astral-sh/uv/issues/13173, but doesn't close
the issue. This just respects preferences if your script uses a
lockfile, since we already support that for locked _projects_.
#5577 fixed a bug on macos due to dynamically linking lzma/xz through
static linking. In #7686, this feature was moved to the performance
category.
This PR moves the `xz2/static` back to the general default features,
and, inspired by https://github.com/Homebrew/homebrew-core/pull/222211,
it structures and documents the feature flags cleaner.
We need to take care that this feature does not accidentally disable
features we want.

## Summary
The only thing that changed for #12175 relevant to the existing
downloads is the order of nesting, so we're checking all nested IO
errors instead of only the first one.
See #13238
## Test Plan
This is an educated guess based on what happens if I turn off the
network during a download.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Fixes#11970.
## Test Plan
<!-- How was it tested? -->
Ran `cargo nextest`
There is a new idna version of testpypi. While we don't select that
version due to the exclude-newer cutoff, the version is still available
to pubgrub as an incompatible choice, changing the error message on
conflicts.
## Summary
Part of #12838. Allow users to configure `python-downloads-json-url` in
`uv.toml` and not just from env.
I followed similar PR #8695, so same as there it's also available in the
CLI (I think maybe it's better not to be configurable from the CLI, but
since the mirror parameters are, I think it's better to do the same)
## Test Plan
<!-- How was it tested? -->
## Summary
In #10939 I added the generated
`crates/uv-python/src/download-metadata-minified.json` file which is a
minified version of `crates/uv-python/download-metadata.json`.
The main reason for this PR is to avoid bloating the git objects as this
is a single-line file.
As a bonus, I also filtered the embed json to include only the versions
for the compiled target. Which should improve the binary size and
performance by a bit.
## Test Plan
<!-- How was it tested? -->
Previously, we were using the wrong `Workspace` discovery and would
report the version of the workspace root, which would iterate up from
the `--project` directory and return the workspace root (with or without
a project in the root). Instead, we need `ProjectWorkspace` discovery
that returns the closest project.
This fixes `uv version --project <path>` where `<path>` belongs to a
workspace member.
Fixes#13213
I think this regressed in https://github.com/astral-sh/uv/pull/13027 — I
misunderstood what versions could be represented in the `pyvenv.cfg` (I
assumed they _never_ included pre-release components).
Closes#13233
uv’s default index strategy was designed with dependency confusion
attacks in mind. [According to the
docs](https://docs.astral.sh/uv/configuration/indexes/#searching-across-multiple-indexes),
“if a package exists on an internal index, it should always be installed
from the internal index, and never from PyPI”. Unfortunately, this is
not true in the case where authentication fails on that internal index.
In that case, uv will simply try the next index (even on the
`first-index` strategy). This means that uv is not secure by default in
this common scenario.
This PR causes uv to stop searching for a package if it encounters an
authentication failure at an index. It is possible to opt out of this
behavior for an index with a new `pyproject.toml` option
`ignore-error-codes`. For example:
```
[[tool.uv.index]]
name = "my-index"
url = "<index-url>"
ignore-error-codes = [401, 403]
```
This will also enable users to handle idiosyncratic registries in a more
fine-grained way. For example, PyTorch registries return a 403 when a
package is not found. In this PR, we special-case PyTorch registries to
ignore 403s, but users can use `ignore-error-codes` to handle similar
behaviors if they encounter them on internal registries.
Depends on #12651Closes#9429Closes#12362
If you pass a TOML file to `uv pip install` that isn't recognized, we
should just reject it instead of assuming `requirements.txt`. I just
don't see a real case where it's better to let the command proceed.
This is a reimplementation of #7248 with a new CLI interface.
The old `uv version` is now `uv self version` (also it has gained a
`--short` flag for parity).
The new `uv version` is now an interface for getting/setting the project
version.
To give a modicum of support for migration, if `uv version` is run and
we fail to find/read a `pyproject.toml` we will fallback to `uv self
version`. `uv version --project .` prevents this fallback from being
allowed.
The new API of `uv version` is as follows:
* pass nothing to read the project version
* pass a version to set the project version
* `--bump major|minor|patch` to semver-bump the project version
* `--dry-run` to show the result but not apply it
* `--short` to have the final printout contain only the final version
* `--output-format json` to get the final printout as json
```
$ uv version
myfast 0.1.0
$ uv version --bump major --dry-run
myfast 0.1.0 => 1.0.0
$ uv version 1.2.3 --dry-run
myfast 0.1.0 => 1.2.3
$ uv version 1.2.3
myfast 0.1.0 => 1.2.3
$ uv version --short
1.2.3
$ uv version --output-format json
{
"package_name": "myfast",
"version": "1.2.3",
"commit_info": null
}
```
Fixes#6298
Some registries (like Azure Artifact) can require you to authenticate
separately for every package URL if you do not authenticate for the
/simple endpoint. These changes make the auth middleware aware of index
URL endpoints and attempts to fetch keyring credentials for such an
index URL when making a request to any URL it's a prefix of.
The current uv behavior is to cache credentials either at the request
URL or realm level. But with these changes, we also need to cache
credentials at the index level. Note that when uv does not detect an
index URL for a request URL, it will continue to apply the old behavior.
Addresses part of #4056Closes#4583Closes#11236Closes#11391Closes#11507
Closes https://github.com/astral-sh/uv/issues/7804
Includes a few small minor changes to the messaging, but the primary
change is that in, e.g., `uvx foo`, if the `foo` package does not
provide the `foo` executable we will no longer execute an arbitrary
`foo` executable if present on the `PATH`. This prevents confusing and
surprising behavior, such as the user reported where they did `uv tool
install foobar` (which provides `foo`) then `uvx foo` (which does not
provide `foo`) later falls back to the executable provided by `foobar`
since it's on the `PATH`. We don't enforce this for `--from`, so things
like `uvx --from foo bash -c "..."` are still totally valid. We also
still allow `uvx foo` where the `foo` executable is provided by a
_dependency_ of `foo` instead of `foo` itself.
Most of the diff here is consolidating the logic of the
`hint_on_not_found` and `warn_executable_not_provided_by_package `
utilities.
## Summary
If you use `--torch-backend=auto`, we want to avoid selecting (e.g.) a
`+cu124` build of `torch` alongside a `+cu126` build of `torchvision`.

## Summary
Part of #8607. This is a pure refactor aimed at paving the way for
supporting the `default-extras` configuration in the `pyproject.toml`
file.
The `ExtraSpecification` struct has been refactored to align more
closely with the
[`DependencyGroups`](256b100a9e/crates/uv-configuration/src/dependency_groups.rs (L9))
struct.
## Test Plan
Existing tests.
## Summary
In https://github.com/astral-sh/uv/pull/12968, we added support for
upload time to `uv.lock`, but stylized as `upload_time`. The other keys
in `uv.lock` use kebab casing, as in common in Python formats, so this
really should've been `upload-time`. I want to change it ASAP to
minimize churn for users. Any users that already upgraded will of course
experience churn in their files a second time. But if we don't change it
now, we'll only increase the surface area of affected users.
So, this PR uses `upload-time` instead, but continues reading
`upload_time` to make it non-breaking.
Part of #11834
Currently, all Python installation are a streaming download-and-extract.
With this PR, we add the `UV_PYTHON_CACHE_DIR` variable. When set, the
installation is split into downloading the interpreter into
`UV_PYTHON_CACHE_DIR` and extracting it there from a second step. If the
archive is already present in `UV_PYTHON_CACHE_DIR`, we skip the
download.
The feature can be used to speed up tests and CI. Locally for me, `cargo
test -p uv -- python_install` goes from 43s to 7s (1,7s in release mode)
when setting `UV_PYTHON_CACHE_DIR`. It can also be used for offline
installation of Python interpreter, by copying the archives to a
directory in the offline machine, while the path rewriting is still
performed on the target machine on installation.
This PR restores #13041 and integrates two PRs from @zanieb:
* #13038
* #13040
It also adds tests for relative URI and fragment handling.
Closes#13037.

Just a small PR to add mentions to `pylock.toml` in the CLI manual where
appropriate.
I tried to say "PEP-751 compatible lock files" when appropriate to also
include the case `r"^pylock\.([^.]+)\.toml$"`. Feel free to change that
if you think it's cluttery.
I also tried to include the "single-use" wording when it made sense.
I also have almost never used the `uv pip` interface, so maybe there are
some other minor things to add here and there about the usage of
`pylock.toml` that I missed.

When working on #13025 I noticed this message was lacking versions,
which seems frustrating if you're debugging things.
I refactored the general `matches_interpreter` utilities that were added
in https://github.com/astral-sh/uv/pull/12884 into a more purpose-fit
function that returns an `Option` with the versions if there's a
mismatch.
This PR restores the `bogus_redirect` test that was
non-deterministically hanging (reverting #13076).
Mismatched package and distribution names were causing uv to hang prior
to #12917 (which added the `bogus_redirect` test). But with that fix, uv
was only checking for mismatched package names on the main thread (and
not the resolver thread). This allowed for a race condition which would
prevent uv from ever doing the check, triggering the original hang
condition. This PR adds the check to the resolver thread to prevent this
race condition.
When an index performs a bogus redirect or otherwise returns a different
distribution name than expected, uv currently hangs.
In the example case, requesting the simple index page for any package
returns the page for anyio. This mean querying the sniffio version map
returns only anyio entries, and the version maps resolves to an anyio
version. When the resolver makes a query for sniffio and waits for it to
resolve, the main thread finds an anyio and resolves only that in the
wait map, causing the hang.
We fix this by checking the name of the returned distribution against
the name of the requested distribution. For good measure, we add the
same check in `Request::Dist` and `Request::Installed`. For performance
and complexity reasons, we don't perform this check in the version map
itself, but only after a candidate distribution has been selected.

## Summary
Fixes several occurrences of the minor typo “This options” for “This
option.”
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
<!-- How was it tested? -->
Since this is just a typo fix in documentation and comment strings, no
particular testing was conducted.
## Notes
The typo fixes in `crates/uv-cli/src/lib.rs` would affect
`docs/reference/cli.md`. I assumed you might want to just re-generate
the reference documention, but fixing it up manually would look like:

## Summary
Provide an in-code switch to permit using the `uv build-backend` command
rather than the default `uv-build` in the Python PEP517 backend. This
option is intended to be used by downstream packagers to provide an
option of reusing `uv` that was built already instead of having to build
a second `uv-build` executable that largely overlaps with `uv`.
Fixes#12389
## Test Plan
The option is intended for downstream consumption only, and it is tested
downstream (via attempting to build a package using the `uv_build`
backend). The backend itself is covered by tests already.

## Summary
We accept `pylock.toml` as a requirements file (e.g., `uv sync
pylock.toml` or `uv pip install -r pylock.toml`). When you provide a
`pylock.toml` file, we don't allow you to provide other requirements, or
constraints, etc. And you can only provide one `pylock.toml` file, not
multiple.
We might want to remove this from `uv pip install` for now, since `pip`
may end up with a different interface (whereas `uv pip sync` is already
specific to uv), and most of the arguments aren't applicable (like
`--resolution`, etc.). Regardless, it's behind `--preview` for both
commands.
## Summary
This PR adds `uv export` support for [PEP
751](https://peps.python.org/pep-0751). We don't yet expose a way to
consume the generated lockfile, but it's a first step.
The logic to go from `uv.lock` to "flat set of packages to include, with
markers telling us when to include them" is all shared with the
`requirements.txt` export (and extracted in
https://github.com/astral-sh/uv/pull/12956). So most of the code is just
converting from our internal types to the PEP 751 schema.
As I suspected quite some time ago
(https://github.com/astral-sh/uv/pull/6738#issuecomment-2315466033),
it's problematic that we don't handle _every_ signal here. This PR adds
handling for all of the Unix signals except `SIGCHLD`, `SIGIO`, and
`SIGPOLL` which seem incorrect to forward. Also notable, we _cannot_
handle `SIGKILL` so if someone sends that to the PID instead of the
PGID, they will leave dangling subprocesses.
Instead, we could use `exec` and avoid this handling. However, we'd lose
the ability to add nice error message on failure (e.g., as someone is
trying to add in https://github.com/astral-sh/uv/pull/12201) and, more
critically, we'd need to figure out how to clean up resources properly
(i.e., temporary directories) which currently happens on `Drop`. In the
long-term, we'll probably want an option to use `exec` — but we'll need
to figure out when to clean up resources or accept that they will
dangle. This was last discussed in
https://github.com/astral-sh/uv/issues/3095 — discussion on that
approach should continue there.
A note on the implementation: I spent time time trying to write the
handler using a tokio stream, so we could dynamically iterate over a
list of signals instead of copy/pasting the implementation — I couldn't
get it to work though and it didn't seem critical.

## Summary
When adding a package with Git reference options (`--rev`, `--tag`,
`--branch`) that already has a Git source defined, use the existing Git
URL with the new reference instead of reporting an error.
This allows commands like `uv add requests --branch main` to work when
requests is already defined with a Git source in the project
configuration.
Previously, you would need to provide the whole Git url again for this
to work:
```bash
uv add git+https://github.com/psf/requests --branch main
```
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
- [x] Add unit tests for project
- [x] Add unit tests for script
- [x] Tested locally for project and script environments like below
### Testing Project
In a directory using the `uv` executable from this PR (via replacing
every `uv` with `cargo run --`) initialize a project and virtual
environment
```bash
uv init
uv venv
```
move into the environment
```bash
# on mac
source .venv/bin/activate
```
and add a dependency with a git url
```bash
uv add git+https://github.com/Textualize/rich --branch master
```
Then change the branch of the project to see that the branch can be
changed without need of the whole git url:
```bash
uv add rich --branch py310
```
### Testing Script
Create the following file, e.g. `script.py`:
```python
import time
from rich.progress import track
print("Starting")
for i in track(range(20), description="For example:"):
time.sleep(0.05)
print("Done")
```
Now using `uv` (referencing the executable of this PR) add the
dependency
```bash
uv add --script script.py 'git+https://github.com/Textualize/rich' --branch master
```
and check we can execute the script:
```bash
uv run script.py
```
To test the change update the branch
```bash
uv add --script script.py rich --branch py310
```
and check that the dependency is updated and the script is executed:
```bash
uv run script.py
```
<!-- How was it tested? -->

This is my first time contributing to `uv` (yay, 🤗) so let me know if
there is something obvious i am missing.
Unit tests will follow soon.

## Summary
This is included in PEP 751, so we lose it when converting from
`uv.lock`. I think it's a good piece of information to include in the
`uv.lock` anyway.
I noticed in the trace output that we weren't obfuscating the
`Credentials` password in a trace message. This PR creates a `Password`
newtype with a custom `Debug` implementation.
uv was failing to authenticate on 302 redirects when credentials were
available. This was because it was relying on `reqwest_middleware`'s
default redirect behavior which bypasses the middleware pipeline when
trying the redirect request (and hence bypasses our authentication
middleware). This PR updates uv to retrigger the middleware pipeline
when handling a 302 redirect, correctly using credentials from the URL,
the keyring, or `.netrc`.
Closes#5595Closes#11097
Fixes#12914.
When `PythonDownloadRequest` does not have the `implementation` set, do
not set it to CPython when calling `fill`, otherwise only CPython
interpreters are shown when listing interpreters available for download,
with `uv python list`.
## Summary
This PR simplifies the version formatting by replacing `.white()` with
`.cyan()` styling for consistency.
Resolves#12940
## Test Plan
I manually recreated the code and tested it with this patch:

## Summary
Untag the `config-settings` value to support JSON schema according to
the
[docs](https://docs.astral.sh/uv/reference/settings/#config-settings).
```toml
[tool.uv]
config-settings = { editable_mode = "compat" }
```
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
Verified using the "Even Better TOML" extension with paths to old and
new `uv.schema.json`.
## Notes
I could not reproduce the issue with either the `taplo` (on which Even
Better Toml is built, afaik) and `check-jsonschema` CLI tools; with both
old and new versions of the `uv.schema.json` validated the
`pyproject.toml`.
Maybe for these there is some additional regularization going on and
that's also how a breaking case ended up in the docs?
I'm unsure on how to test for this.
After about an hour, the Even better TOML VSCode extension was the only
way to reproduce failing validation.
Let me know if I can do something else.
<!-- How was it tested? -->
Currently, `uv init` works without a `git` executable, and with a
working `git` executable, but not with a broken `git`, be it from GitHub
Action's Windows CI or from the shim we insert.
`uv init` calls git twice: Once `git rev-parse` to check whether a git
repo already exists, and then `git init` (if there is no git repository
yet and no `--vcs none`).
By separately handling the cases where git failed during `git rev-parse`
doesn't work vs. where the is no repository when checking for an
existing repo work tree, we can avoid calling `git init` for broken git
and erroring. We have to hardcode the expected git command outputs to be
able to check.
This is a rebased and updated version of #11925 based on my review (I
didn't have permission to push to their branch).
For posterity I've preserved their commits but my final commit
essentially rewrites the whole thing anyway.
Fixes#11637

"Only show Python downloads, exclude installed distributions." might be
misunderstood as excluding installed distributions from `uv python list
--only-downloads`, implying that versions already installed won’t be
shown.
See #12769 for the motivation. We set the 4MB not only for the main
thread, but also for all tokio and rayon threads to fix a stack overflow
while unpacking wheels in production on Windows.
There are two variables for setting the stack size: A new
`UV_STACK_SIZE` that takes precedent, and the existing `RUST_MIN_STACK`.
When setting the stack size, `UV_STACK_SIZE` should be preferred, since
`RUST_MIN_STACK` affects all Rust applications, including build backends
we call (e.g., maturin). The minimum stack size is set to 1MB, the
lowest stack size we observed on a platform (Windows main thread).
Fixes#12769
## Test Plan
Tested manually with the example from #12769
## Summary
Closes#12855
This PR also fixed an issue, where `python_request` was matched against
`PythonVersion::Default`. Previously, if `python_request` was `3.13t`,
it would match the last branch, triggering a download of the Python
version if it wasn't already installed.

```
It was possible that a virtual environment became out of sync with the
interpreter it pointed to (for example, if a symlink was changed to an
updated Python version). In such a case, `pyvenv.cfg` and
`activate_this.py` would no longer be correct. This PR detects when the
`version` (`venv` module) or `version_info` (uv and `virtualenv`) field
in `pyvenv.cfg` is out of sync with the interpreter. In such a case, uv
recreates the virtual environment.
Closes#12461
We have been claiming in our releases that we provide
archives/installers for uv-build, but we only upload it as a wheel to
pypi. This is because cargo-dist tries to be helpful and find all your
apps, but this scales poorly to large workspaces like ours, as stuff
like this slips in. So invert the default and make uv the only package
dist will see until we say otherwise.
See e.g. https://github.com/astral-sh/uv/releases/tag/0.6.14Fixes#12883
By default, unlike on CI, a Windows machine does not allow creating
symlinks, so we have to unix-gate tests that assume symlinks.
We can't install the transformers ecosystem test on Windows due to
missing torch, so it is also unix-gated.
Windows translates error messages, so we have to filter the "File not
found" message, since it can also be a "Datei nicht gefunden".

From PEP 440:
> The exclusive ordered comparison <V MUST NOT allow a pre-release of
the specified version unless the specified version is itself a
pre-release. Allowing pre-releases that are earlier than, but not equal
to a specific pre-release may be accomplished by using <V.rc1 or
similar.
We had an additional check that would block this even if the specifier
did have a pre-release.
This likely didn't show up earlier because `Ranges` uses different code
in the resolver.
I checked these changes against `packaging` to verify their behavior:
```python
print(SpecifierSet("<1").contains("1a1", prereleases=True)) # False
print(SpecifierSet("<1a2").contains("1a1", prereleases=True)) # True
print(SpecifierSet("<1").contains("1dev1", prereleases=True)) # False
print(SpecifierSet("<1dev2").contains("1dev1", prereleases=True)) # True
print(SpecifierSet("<1a2").contains("1dev1", prereleases=True)) # True
```
Closes#12834
## Summary
This PR errors out when an Unknown Dependency Object Specifier is used
in dependency groups.
Fixes#12638
## Test Plan
The current behaviour is as follows:
```bash
➜ example git:(12638/dependency-object-specifier) ✗ cargo run -- sync
Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.21s
Running `/home/luna/Documents/uv/target/debug/uv sync`
error: Failed to generate package metadata for `example==0.1.0 @ virtual+.`
Caused by: Group `bar` contains a Dependency Object Specifier, which is not supported by uv
```
And the pyproject.toml to produce this is:
```toml
[project]
name = "example"
version = "0.1.0"
description = "Add your description here"
readme = "README.md"
requires-python = ">=3.13.2"
dependencies = []
[dependency-groups]
foo = ["pyparsing"]
bar = [{set-phasers-to = "stun"}]
```
## Summary
Closes#12806
Split `UV_INDEX` by any whitespace rather than only ASCII 32, which does
not align with the behavior of `PIP_EXTRA_INDEX_URL` and can possibly
lead to difficulties when migrating from pip to uv.
Clap unfortunately does not support passing multiple delimiters, writing
a custom parsing function involved parsing index into a Vec<Vec<Index>>
and flattening it afterwards in order to avoid breaking the --index
command line option.
There might be a prettier solution I overlooked, let me know if there is
anything I should change!

Check that the source and module directory exist when build a source
distribution, instead of delaying the check to building the wheel. This
prevents building source distributions that can never be built into
wheels.
I removed the `set_cksum` as the value of it is replaced inside of
`append_data`.

This should fix#12762 but I don't know how to test it.

## Summary
I think the lack of enforcement here is an oversight. We _do_ already
enforce this for user-level configuration files (contrary to the issue
-- at least, in my testing and from reading the code).
Closes https://github.com/astral-sh/uv/issues/12753.
## Summary
See the test cases. Previously, you could end up with something like:
```toml
[tool.uv.workspace]
members = [
"foo",
"bar",
"baz", "bop",
]
```

## Summary
Fixes#12606.
Two options considered, thanks to @zanieb's guidance are:
1. Special-casing on parse error and encountering the `environment.yml`
filename, possibly at `RequirementsTxt::parse`
2. Adding a new `RequirementsSource::EnvironmentYml` variant and
erroring on `RequirementSpecification::from_source`
I went with the latter for the following reasons:
- This edge case is explicitly modelled within the type system. However,
it changes the semantics of `RequirementsSource` to also model
_unsupported_ sources.
- (**Separation of concerns**) The special-casing would occur in the
`uv-requirements-txt` crate, which seems to be relatively deep in the
guts of the codebase. In my opinion, maintainers working in
`uv-requirements-txt` would reasonably assume the input file to be a
`requirements.txt` file, instead of having to be concerned with it being
another file format (`environment.yml`, `pyproject.toml`, etc.)
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
Manually tested as follows:
```sh
>>> cargo run -- pip install -r environment.yml
error: Conda environment file `environment.yml` is not supported
>>> cargo run -- add -r environment.yml
error: Conda environment file `environment.yml` is not supported
```
If you can point me to the appropriate test module, I can write up tests
for these to use `insta`.
<!-- How was it tested? -->
## Summary
Add an option to overwrite the list of available Python downloads from a
local JSON file by using the environment variable
`UV_PYTHON_DOWNLOADS_JSON_URL`
as an experimental support for providing custom sources for Python
distribution binaries #8015
related #10203
I probably should make the JSON to be fetched from a remote URL instead
of a local file.
please let me know what you think and I will modify the code
accordingly.

@jtfmumm mentioned a desire for this. I'm not sure how we should do
this. I kind of want to change this to something like...
```
$ uv python find
CPython 3.13 @ <path>
$ uv python find --only-path
<path>
$ uv python find --short
<path>
$ uv python find --only-version
3.13
```
The change in defaults would be breaking though.
uv has a global `--no-config` option, which indeed has an effect.

## Summary
Fix a suggestion in the docs on configs through environment variables,
which lists an option value that doesn't appear to exist.
The description implies that `unsafe-best-match` was intended here.
## Test Plan
Verified by providing `unsafe-any-match` as a parameter to `uv`. It
didn't error, but appeared to use the `first-index` strategy instead.
The value I changed it to behaves as described by the documentation.
In an attempt to avoid reporting shims as their resolved
`sys.executable` path, we report the queried executable path instead.
This seems more correct for this command, broadly? Interestingly, it
changes the reported paths for Homebrew Python

This will in principle fix the problem reported in #12611 that
`authenticate = "always"` is ignored for an index when `explicit =
true`. This change ensures all indexes are added to the URL auth
policies list passed to our auth middleware.

clear if there's any cases where these checks are overzealous.
## Summary
I noticed that these only support Basic credentials, but we may want to
allow users to provide Bearer tokens? This PR just generalizes the type.
serde needs to be told where to put underscores. someone clearly noticed
this when adding attributes for schemars, but they need to be present
for serde too and then schemars gets them for free.
Strictly speaking this would be a breaking change for anyone who noticed
the parsing was messed up and worked around it. So we add aliases for
backcompat, at least for a few releases.

## Summary
The overall strategy here is to make this code look more like
`requirements_txt.rs`: we seed the root members, then perform a DFS.
Previously, we created all nodes upfront, which caused problems when
using `--only-group`, since we'd omit "production" dependencies of
development dependencies.
Closes https://github.com/astral-sh/uv/issues/12526.
Adding dependency trace/parent comments ("via ...") to the export
command output.
This is a similar behavior to the pip compile output.
#### Note to the eager reviewer:
First of all - thanks!
Secondly, this is still a very rough draft. These are the first lines of
code I've ever written in Rust. This is still mostly an educational/fun
exercise for myself. If opening a Draft PR is creating too much noise -
I apologize and I will close it until it is ready.

## Summary
uv doesn't separate the metadata block from other blocks when adding the
`script` block to a script, which results in the next block being
considered part of the script block and causes errors when running.
See #12499 for more details.
Closes#12499
## Test Plan
I manually tested the most common scenario, but there's a few edge cases
that would be good to have tests for.
I would have written the tests also, but I was running into errors like
this:
```bash

## Summary
We tend not to run tests for individual crates, which can lead to weird
situations like this, where crates are missing optional features that
are otherwise installed globally.
## Test Plan
Run `cargo test --profile fast-build -p uv-scripts`, which otherwise
fails to compile.
The idea here is that we introduce a new stdout_important method for
things that want to care about the difference between "quiet" and
"silent".
This PR is WIP because it has no actual uses of stdout_important, and we
should have at least one before landing this. Perhaps someone has a
suggestion for commands that would really benefit from this distinction?
Fixes#10431
## Summary
This PR extends `[[tool.uv.index]]` to support `--find-links`-style
"flat" indexes, so that users can point to such indexes without using
`--find-links` _and_ get access to the full functionality of
`[[tool.uv.index]]` (e.g., they can now pin packages to
`--find-links`-style indexes).
Note that, at present, `--find-links` indexes actually have some quirky
behavior, in that we combine them into a single entity and then merge
the discovered distributions into each Simple API-style index. The
motivation here, IIRC, was to match pip's behavior quite closely. I'm
interested in _removing_ that behavior, but it'd be breaking (and may
also be inconvenient for some use-cases). So, the behavior for indexes
passed in via `--find-links` remains completely unchanged. However,
`[[tool.uv.index]]` entries with `format = "flat"` are now treated
identically to those defined with `format = "simple"` (the default), in
that we stop after we find the first-matching index, etc.
Closes https://github.com/astral-sh/uv/issues/11634.
## Summary
I don't know if I actually want to commit this, but I did it on the
plane last time and just polished it off (got it to compile) while
waiting to board.
We were not applying the `authenticate = "always"` behavior to `uv pip`
commands (related to #12362). This PR addresses that, applying
authentication policies wherever we set up a registry client.
## Summary
This fixes https://github.com/astral-sh/uv/issues/12426 which helps use
a more accurate arg name in the help output.
## Test Plan
I didn't test it locally, @charliermarsh gave me guidance on what to
change so I looked around that file for another example of `value_name`
and repeated what I saw. I kept it formatted to 1 line based on it not
being a long line. The other example of `value_name` had everything on
separate lines because there were a bunch of parameters passed in.

## Summary
This PR modifies the requirement source entities to store a (new)
container struct that wraps `IndexUrl`. This will allow us to store
user-defined metadata alongside `IndexUrl`, and propagate that metadata
throughout resolution.
Specifically, I need to store the "kind" of the index (Simple API vs.
`--find-links`), but I also ran into this problem when I tried to add
support for overriding `Cache-Control` headers on a per-index basis: at
present, we have no way to passing around metadata alongside an
`IndexUrl`.
Match the module name to its module directory with potentially different
casing.
For example, a package may have the dist-info-normalized package name
`pil_util`, but the importable module is named `PIL_util`.
We get the module name either as dist-info-normalized package name, or
explicitly from the user. For dist-info-normalizing a package name, the
rules are lowercasing, replacing `.` with `_` and replace `-` with `_`.
Since `.` and `-` are not allowed in module names, we can check whether
a directory name matches our expected module name by lowercasing it.
Fixes#12187

## Summary
In general, we merge `--find-links` entries into each index. If a
package is pinned to an index, though, it seems surprising (and wrong)
that we'd ever select a distribution from `--find-links`. This PR
modifies the provider to ignore `--find-links` for any explicitly pinned
packages.
Allows `uv python list <request>` to filter the installed list. I often
want this and it's not hard to add.
I tested the remote download filtering locally (#12381 is needed for
snapshot tests)

## Summary
I want to use the flat index client from within the registry client, so
making them both depend on the same underlying primitives rather than
having the flat index client depend on the registry client.
## Summary
We respect `--exclude-newer` during resolution, but we weren't applying
it to individual _files_ when writing the lockfile. As a result, if
wheels were added to a distribution after its initial release, we'd end
up including them in the lockfile, even if they were uploaded after the
`--exclude-newer` date.
Closes https://github.com/astral-sh/uv/issues/12296.
## Summary
It's possible that the PyTorch version the user depends on isn't in the
latest index. These indexes are equally trusted, so we should override
the policy.
Closes#12357.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
This fixes a case described in #12333, where trailing comments in
dependencies can be unexpectedly shifted when a new dependency is added.
Fixes#12333.

`cargo test` (Added a snapshot test)
## Summary
Resolves#11794.
When `uv python find` is given a `--script` option, either the existing
environment for that script or the Python executable that would be used
to create it will be returned. If neither are found, the command exits
with exit code 1.
`--script` is incompatible with all other options to the same command.
## Test Plan
Unit tests.
## Summary
This crate is for standards-compliant types, but this is explicitly a
type that's custom to uv. It's also strange because we kind of want to
reference `IndexUrl` on the registry type, but that's in a crate that
_depends_ on `uv-pypi-types`, which to me is a sign that this is off.
There was a bug where `UV_MANAGED_PYTHON` and `UV_NO_MANAGED_PYTHON`
only accepted `true` or `false`. This switches to the boolish value
parser for those flags.
Closes#12336
## Summary
Fixes the failing `cache_prune::prune_unzipped` test that was causing CI
failures in my other PR (#12328) and others like PR #12327.
The error message format changed to show a specific version constraint
(`iniconfig<=2.0.0`) rather than the generic 'all versions' message.
This PR updates the test to expect the new, more specific error message.
## Test Plan
Ran `cargo test -p uv cache_prune::prune_unzipped` to verify the test
now passes.
Previously, we required a username to perform a fetch from the keyring
because the `keyring` CLI only supported fetching password for a given
service and username. Unfortunately, this is different from the keyring
Python API which supported fetching a username _and_ password for a
given service. We can't (easily) use the Python API because we don't
expect `keyring` to be installed in a specific environment during
network requests. This means that we did not have parity with `pip`.
Way back in https://github.com/jaraco/keyring/pull/678 we got a `--mode
creds` flag added to `keyring`'s CLI which supports parity with the
Python API. Since `keyring` is expensive to invoke and we cannot be
certain that users are on the latest version of keyring, we've not added
support for invoking keyring with this flag. However, now that we have a
mode that says authentication is _required_ for an index (#11896), we
might as well _try_ to invoke keyring with `--mode creds` when there is
no username. This will address use-cases where the username is
non-constant and move us closer to `pip` parity.
This addresses a small part of #12280, namely when you have
`authenticate` set to `always`, it will output a distinct error message
for the case where you have a username but are missing a password.
## Summary
This is a prototype that I'm considering shipping under `--preview`,
based on [`light-the-torch`](https://github.com/pmeier/light-the-torch).
`light-the-torch` patches pip to pull PyTorch packages from the PyTorch
indexes automatically. And, in particular, `light-the-torch` will query
the installed CUDA drivers to determine which indexes are compatible
with your system.
This PR implements equivalent behavior under `--torch-backend auto`,
though you can also set `--torch-backend cpu`, etc. for convenience.
When enabled, the registry client will fetch from the appropriate
PyTorch index when it sees a package from the PyTorch ecosystem (and
ignore any other configured indexes, _unless_ the package is explicitly
pinned to a different index).
Right now, this is only implemented in the `uv pip` CLI, since it
doesn't quite fit into the lockfile APIs given that it relies on feature
detection on the currently-running machine.
## Test Plan
On macOS, you can test this with (e.g.):
```shell
UV_TORCH_BACKEND=auto UV_CUDA_DRIVER_VERSION=450.80.2 cargo run \
pip install torch --python-platform linux --python-version 3.12
```
On a GPU-enabled EC2 machine:
```shell

```
## Summary
I think this is reasonable to change. Right now, if you're on Python
3.11, the resolver returns `multiprocess-0.70.17-py311-none-any.whl`,
but `multiprocess-0.70.17-py310-none-any.whl` is in the cache, we'll
reuse `multiprocess-0.70.17-py310-none-any.whl` (since it _is_
compatible with Python 3.11).
Instead, we now _require_ the cached wheel to match the wheel returned
by the resolver.
Closes https://github.com/astral-sh/uv/issues/12273.
Currently, for users to specify at the command line whether to use
uv-managed or system Python interpreters, they use the
`--python-preference` parameter, which takes four possible values. This
is more complex than necessary since the normal case is to either say
"only managed" or "not managed". This PR hides the old
`--python-preference` parameter from help and documentation and adds two
new flags: `--managed-python` and `--no-managed-python` to capture the
"only managed" and "not managed" cases.
I have successfully tested this locally but currently cannot add
snapshot tests because of problems with distinguishing managed vs.
system interpreters in CI (and non-determinism when run on different
developers' machines). The `--python-preference` test in
`tool-install.rs` is currently ignored for this reason. See #5144 and
#7473.

## Summary
I suspect this only affects packages with quotes in the requires-python,
which is typically an error but one that we correct for in
`LenientVersionSpecifiers`.
Closes https://github.com/astral-sh/uv/issues/12260.
Reject lockfiles where the package version and the wheel versions are
incoherent. This implicitly checks that all wheel files have the same
version.
It does not check for the source dist version, since a source dist may
not contain a version in the filename and attempting to deserialize
source dist filenames we may not need is a performance overhead for
something that's already slow in `uv run`.
Fixes#12164
## Summary
This has come up a few times, so it seems worth addressing. If you
migrate from a flat layout to a `src` layout or vice versa, we now
invalidate the package metadata.
Closes https://github.com/astral-sh/uv/issues/12047
## Summary
This ended up being more involved than expected. The gist is that we
setup all the packages we want to reinstall upfront (they're passed in
on the command-line); but at that point, we don't have names for all the
packages that the user has specified. (Consider, e.g., `uv pip install
.` -- we don't have a name for `.`, so we can't add it to the list of
`Reinstall` packages.)
Now, `Reinstall` also accepts paths, so we can augment `Reinstall` based
on the user-provided paths.
Closes#12038.
This is a minimal redux of #10861 to be compatible with `uv pip`.
This implements the interface described in:
https://github.com/pypa/pip/pull/13065#issuecomment-2544000876 for `uv
pip install` and `uv pip compile`. Namely `--group <[path:]name>`, where
`path` when not defined defaults to `pyproject.toml`.
In that interface they add `--group` to `pip install`, `pip download`,
and `pip wheel`. Notably we do not define `uv pip download` and `uv pip
wheel`, so for parity we only need to implement `uv pip install`.
However, we also support `uv pip compile` which is not part of pip
itself, and `--group` makes sense there too.
----
The behaviour of `--group` for `uv pip` commands makes sense for the
cases upstream pip supports, but has confusing meanings in cases that
only we support (because reading pyproject.tomls is New Tech to them but
heavily supported by us). **Specifically case (h) below is a concerning
footgun, and case (e) below may get complaints from people who aren't
well-versed in dependency-groups-as-they-pertain-to-wheels.**
## Only Group Flags
Group flags on their own work reasonably and uncontroversially, except
perhaps that they don't do very clever automatic project discovery.
a) `uv pip install --group path/to/pyproject.toml:mygroup` pulls up
`path/to/project.toml` and installs all the packages listed by its
`mygroup` dependency-group (essentially treating it like another kind of
requirements.txt). In this regard it functions similarly to
`--only-group` in the rest of uv's interface.
b) `uv pip install --group mygroup` is just sugar for `uv pip install
--group pyproject.toml:mygroup` (**note that no project discovery
occurs**, upstream pip simply hardcodes the path "pyproject.toml" here
and we reproduce that.)
c) `uv pip install --group a/pyproject.toml:groupx --group
b/pyproject.toml:groupy`, and any other instance of multiple `--group`
flags, can be understood as completely independent requests for the
given groups at the given files.
## Groups With Named Packages
Groups being mixed with named packages also work in a fairly
unsurprising way, especially if you understand that things like
dependency-groups are not really supposed to exist on pypi, they're just
for local development.
d) `uv pip install mypackage --group path/to/pyproject.toml:mygroup`
much like multiple instances of `--group` the two requests here are
essentially completely independent: pleases install `mypackage`, and
please also install `path/to/pyproject.toml:mygroup`.
e) `uv pip install mypackage --group mygroup` is exactly the same, but
this is where it becomes possible for someone to be a little confused,
as you might think `mygroup` is supposed to refer to `mypackage` in some
way (it can't). But no, it's sourcing `pyproject.toml:mygroup` from the
current working directory.
## Groups With Requirements/Sourcetrees/Editables
Requirements and sourcetrees are where I expect users to get confused.
It behaves *exactly* the same as it does in the previous sections but
you would absolutely be forgiven for expecting a different behaviour.
*Especially* because `--group` with the rest of uv *does* do something
different.
f) `uv pip install -r a/pyproject.toml --group b/pyproject.toml:mygroup`
is again just two independent requests (install `a/pyproject.toml`'s
dependencies, and `b/pyproject.toml`'s `mygroup`).
g) `uv pip install -r pyproject.toml --group mygroup` is exactly like
the previous case but *incidentally* the two requests refer to the same
file. What the user wanted to happen is almost certainly happening, but
they are likely getting "lucky" here that they're requesting something
simple.
h) `uv pip install -r a/pyproject.toml --group mygroup` is again exactly
the same but the user is likely to get surprised and upset as this
invocation actually sources two different files (install
`a/pyproject.toml`'s dependencies, and `pyproject.toml`'s `mygroup`)! I
would expect most people to assume the `--group` flag here is covering
all applicable requirements/sourcetrees/editables, but no, it continues
to be a totally independent reference to a file with a hardcoded
relative path.

There were no GraalPy binary wheels were available when uv support was
added, and thus the abi tag was never tested against actual packages.
Now that GraalPy publishes binary wheels to

incorrect and the version info incorrectly determined.

In #10669, a pyproject.toml with requires-python but no environment had
a lockfile covering only a subset of the requires-python space:
```toml
resolution-markers = [
"python_full_version >= '3.10' and platform_python_implementation == 'CPython'",
"python_full_version == '3.9.*'",
"python_full_version < '3.9'",
]
```
This marker set is invalid, we have to reject the lockfile. (We can
still use the versions though, to avoid churn).
Part 1/2 of #10669
These changes add support for
```
uv python pin 3.12 --global
```
This adds the specified version to a `.python-version` file in the
user-level config directory. uv will now use the user-level version as a
fallback if no version is found in the project directory or its
ancestors.
Closes#4972
When making changes to uv that require new (or altered) settings, there
are many places in the code that need to change. This slows down work,
reduces confidence in changes for new developers, and adds noise to PRs.
The goal of this PR is to reduce the number of points that need to
change (and that the developer needs to understand) when making changes
to settings.
This PR consolidates `ResolverSettings` and `ResolverInstallerSettings`
by factoring out the shared settings and using a new field
`resolver_settings` on `ResolverInstallerSettings`. This not only
reduces repetition, but makes it easier for a human to parse the code
without having to compare long lists of fields to spot differences (the
difference was that `ResolverInstallerSettings` had two extra fields).
This also removes `ResolverSettingsRef` and
`ResolverInstallerSettingsRef`, using normal Rust references instead.
For the time being, I've left `InstallerSettingsRef` in place because it
appears to have a semantic meaning that might be relied upon. However,
it would now be straightforward to refactor to pass
`&ResolverInstallerSettings` wherever `InstallerSettingsRef` appears,
further reducing sprawl.
The change has the downside of adding
`settings.resolver_settings.<field>` and requiring dereferencing at
various points where it was not required before (with the *SettingsRef
approach). But this means there are significantly fewer places that must
change to update settings.
Following the upstream release and #12120, removes gating preventing
installation of the managed musl Python versions.
Of note
- The filtering of musl Python distributions has moved from the Rust
runtime to the metadata fetcher
- The filtering is now conditional on the PBS release date, removing all
old static musl distributions
- We could support the `+static` musl downloads in the future; right
now, they are deprioritized when selecting a variant
- I added test to CI which uses Alpine and installs numpy

## Summary
This PR is meant to fix issue #11862
It allows to send sized bodies during `publish`
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
the PR was tested on the MRE from #11862
<!-- How was it tested? -->
## Summary
Follow up to https://github.com/astral-sh/uv/pull/11888 with added
support for uv tool run.
Changes
* Added functionality for running windows scripts in previous PR was
moved from run.rs to uv_shell::runnable.
* EXE was added as a supported type, this simplified integration across
both uv run and uvx while retaining a backwards compatible behavior and
properly prioritizing .exe over others. Name was adjusted to runnable as
a result to better represent intent.
## Test Plan
New tests added.
## Documentation
Added new documentation.
Reduce the overhead of `uv run` in large workspaces. Instead of
re-discovering the entire workspace each time we resolve the metadata of
a member, we can the discovered set of workspace members. Care needs to
be taken to not cache the discovery for `uv init`, `uv add` and `uv
remove`, which change the definitions of workspace members.
Below is apache airflow e3fe06382df4b19f2c0de40ce7c0bdc726754c74 `uv run
python` with a minimal payload. With this change, we avoid a ~350ms
overhead of each `uv run` invocation.
```
$ hyperfine --warmup 2 \
"uv run --no-dev python -c \"print('hi')\"" \
"uv-profiling run --no-dev python -c \"print('hi')\""
Benchmark 1: uv run --no-dev python -c "print('hi')"
Time (mean ± σ): 492.6 ms ± 7.0 ms [User: 393.2 ms, System: 97.1 ms]
Range (min … max): 482.3 ms … 501.5 ms 10 runs
Benchmark 2: uv-profiling run --no-dev python -c "print('hi')"
Time (mean ± σ): 129.7 ms ± 2.5 ms [User: 105.4 ms, System: 23.2 ms]
Range (min … max): 126.0 ms … 136.1 ms 22 runs
Summary
uv-profiling run --no-dev python -c "print('hi')" ran
3.80 ± 0.09 times faster than uv run --no-dev python -c "print('hi')"
```
The profile after those change below. We still spend a large chunk in
toml parsing (both `uv.lock` and `pyproject.toml`), but it's not
excessive anymore.

Adds a new optional key `auth-policy` to `[tool.uv.index]` that sets the
authentication policy for the index URL.
The default is `"auto"`, which attempts to authenticate when necessary.
`"always"` always attempts to authenticate and fails if the endpoint is
unauthenticated. `"never"` never attempts to authenticate.
These policy address two kinds of cases:
* Some indexes don’t fail on unauthenticated requests; instead they just
forward to the public PyPI. This can leave the user confused as to why
their package is missing. The "always" policy prevents this.
* "never" allows users to ensure their credentials couldn't be leaked to
an unexpected index, though it will only allow for successful requests
on an index that doesn't require credentials.
Closes#11600
In the publish client, we have to set the client retries to 0 as the
retry middleware is incompatible with upload bodies. This however also
sets `client.retry_policy()` to a zero-retry policy, so we need to
construct our own policy.

This PR moves functions for finding user- and system-level config
directories to public functions in `uv_fs::config`. This will allow them
to be used in future work without duplicating code.
This adds support for inferring dependency group conflict sets from the
directly defined conflicts in configuration. For example, if you declare
a conflict between groups `alpha` and `beta` and `dev` includes `beta`,
then we will infer a conflict between `dev` and `alpha`. We will also
handle a conflict between two groups if they transitively include groups
that conflict with each other. See #11232 for more details.
Closes#11232
## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
The way the `tool update-shell` checks if the command to export the PATH
exists or not in the RC files is a blind search, and therefore if finds
the command inside comments.
example with .zshenv
This content
```
# uv
# export PATH="/Users/cholas/.local/bin:$PATH"
```
Generates the following msg
```
error: The executable directory /Users/cholas/.local/bin is not in PATH, but the Zsh configuration files are already up-to-date
```
With this change, that content won't be considered as configured and the
following will be added
```
# uv
export PATH="/Users/cholas/.local/bin:$PATH"
```
This will make the `update-shell` more reliable
## Test Plan
I tested with and without the change with commented export in zsh in
mac. Tested running `cargo run -- tool update-shell`

I somehow missed running an actual integration test of the PEP 517 API
in CI and the python shim was using the old uv CLI interface still.
The tests include pip, uv and `python -m build`. They must be a in CI
job since we can't depend on the Python package in the Rust tests (we
only get the binary in `cargo test`, not the `uv_build` wheel).
## Summary
The order here is slightly off... As-is, we fetch the metadata for the
dependency, _then_ insert the URLs and indexes into the fork state -- so
the fetch doesn't take the explicit index or URL into account. This has
mostly been unobserved because we re-fetch anyway in the next request,
but if we do things in the right order (add to fork state, fetch
dependencies, insert dependencies), we can cut down on the fetches.
Closes https://github.com/astral-sh/uv/issues/12056.
Thank you for uv, it has game-changer capabilities in the field of
Python package and environment maangement!
## Summary
This is a small PR adding the option `module-name`
(`tool.uv.build-backend.module-name`) to the uv build backend (
https://github.com/astral-sh/uv/issues/8779 ).
Currently, the uv build backend will assume that the module name matches
the (dash to underdash-transformed) package name. In some packaging
scenarios this is not the case, and currently there exists no
possibility to override it, which this PR addresses.
From the main issue ( https://github.com/astral-sh/uv/issues/8779 ) I
could not tell if there is any extensive roadmap or plans how to
implement more complex scenarios, hence this PR as a suggestion for a
small feature with a big impact for certain scenarios.
I am new to Rust, I hope the borrow/reference usage is correct.
## Test Plan
So far I tested this at an example, if desired I can look into extending
the tests.

This PR is in support of #12005, where we need to import
`DependencyGroups` in the `uv-pypi-types` crate without a circular
dependency on `uv-workspace`.
uv itself is a large package with many dependencies and lots of
features. To build a package using the uv build backend, you shouldn't
have to download and install the entirety of uv. For platform where we
don't provide wheels, it should be possible and fast to compile the uv
build backend. To that end, we're introducing a python package that
contains a trimmed down version of uv that only contains the build
backend, with a minimal dependency tree in rust.
The `uv_build` package is publish from CI just like uv itself. It is
part of the workspace, but has much less dependencies for its own
binary. We're using cargo deny to enforce that the network stack is not
part of the dependencies. A new build profile ensure we're getting the
minimum possible binary size for a rust binary.

## Summary
In https://github.com/astral-sh/uv/issues/11998, a user is attempting to
vendor `pydantic-core`. But when they add `pydantic-core = { path =
"src/foo/vendor/pydantic-core" } `, we're installing it as a virtual
package, since `pydantic-core/pyproject.toml` contains `package =
false`.
This PR allows users to mark dependencies as "explicitly a package" or
"explicitly not a package" (i.e., virtual), as a workaround.
Closes https://github.com/astral-sh/uv/issues/11998.
## Summary
This PR adds support for `SitePackages::satisfies` with unnamed
overrides and requirements.
The main challenge here was cases like: you have a `requirements.in`
with `git+https://github.com/pallets/flask` in it, and an
`overrides.txt` with `flask==2.0.0` in it. You _need_ to include
`flask==2.0.0`, but you can't know that without resolving the unnamed
URL requirement (since overrides only take effect when the package is
included, like constraints).
We now make the assumption that any unnamed overrides _are_ relevant,
for the purpose of the satisfies check. This is conservative, but this
whole check is an optimization anyway.
## Summary
Closes https://github.com/astral-sh/uv/issues/9151
This adds support for running .ps1, .cmd, .bat legacy scripts typically
provided by setuptools [legacy script
files](https://packaging.python.org/en/latest/guides/distributing-packages-using-setuptools/#scripts).
Note, .bat and .cmd scripts were somewhat supported previously by
[Command](https://doc.rust-lang.org/std/process/index.html#batch-file-special-handling)
when the extension was explicit but documentation says such behavior
should not be relied upon.
In addition, when no extension is provided and a legacy script exists,
it will try to infer the appropriate extension on Windows and use the
right runtime with preference for .ps1. Only powershell.exe and cmd.exe
are supported right now.
## Test Plan
Added tests. Tested with nuitka locally via uv run.
Note uvx support will be added in a follow up.
## Summary
Small omission I noticed last night. This was overly strict (so, didn't
lead to any incorrect behavior; more that we did unnecessary work in
some cases).

<!-- What's the purpose of the change? What does it do, and why? -->
Similar to https://github.com/astral-sh/uv/pull/11399

Tested manually and with snapshot tests.

## Summary
If we're looking at (e.g.) `python3.12`, and we have a `requires-python:
">=3.12.7, <3.13"`, then checking if the range includes `3.12` will
return `false`. Instead, we need to look at the lower- and upper-bound
major-minors of the `requires-python`.
Closes https://github.com/astral-sh/uv/issues/11825.
We prepend the interpreter discovery in a temporary path to `sys.path`,
which we have to strip to avoid the `sys.path` value containing a
then-deleted temp dir.
If we see `uvx script.py`, we exit early, giving a hint to use `uv run
script.py` if the script exists. If it does not exist, we suggest
running `uv run` with a normalized package name.
This PR includes a snapshot test for each of these scenarios.
An alternative approach would be to wait until we encounter an error,
and then add the hint. But if there happens to be a malicious package
called `script-py`, this would be run unintentionally (a point raised by
@zanieb).
Closes#10784

## Summary
I believe `zlib-rs` is now a better choice on ARM and x86, so I'm just
going to assume it's a better choice everywhere. It's much easier to
build (removes our CMake dependency), and in my benchmarking, it's
substantially faster on ARM and faster or ~exactly even on my x86
Windows machine.
We migrated to `zlib-rs` once before (#9184); however, I later reverted
it as I learned that they were only doing compile-time feature
detection, and so `zlib-rs` was meaningfully slower on x86. They now
perform runtime feature detection:
https://trifectatech.org/blog/zlib-rs-is-faster-than-c/.
To benchmark, I wrote a script to create a local Simple API-compliant
registry (see the commit history) for a single package. Then I ran the
`install-cold` benchmark against that registry to install NumPy.
On ARM:
```
❯ uv run resolver --uv-pip-path ../../zlib-ng --uv-pip-path ../../zlib-rs \
--benchmark install-cold \
req.txt --warmup 10 --min-runs 30
Benchmark 1: ../../zlib-ng (install-cold)
Time (mean ± σ): 165.7 ms ± 34.7 ms [User: 64.4 ms, System: 93.2 ms]
Range (min … max): 141.8 ms … 293.2 ms 30 runs
Benchmark 2: ../../zlib-rs (install-cold)
Time (mean ± σ): 150.9 ms ± 16.2 ms [User: 57.4 ms, System: 86.4 ms]
Range (min … max): 135.3 ms … 202.4 ms 30 runs
Summary
../../zlib-rs (install-cold) ran
1.10 ± 0.26 times faster than ../../zlib-ng (install-cold)
```
I benchmarked this about 100 times on my Windows machine and found it
difficult to conclude anything beyond "They're nearly the same". Here's
an example:
```
PS C:\Users\crmar\workspace\puffin> hyperfine --prepare "uv venv" "zlib-rs.exe pip sync ./scripts/benchmark/req.txt" "zlib-ng.exe pip sync ./scripts/benchmark/req.txt" "zlib-rs.exe pip sync ./scripts/benchmark/req.txt" "zlib-ng.exe pip sync ./scripts/benchmark/req.txt" --runs 10 --warmup 5

1.02 ± 0.05 times faster than zlib-ng.exe pip sync ./scripts/benchmark/req.txt
```
Closes#11885.
At certain points in the code, dependency groups are represented by
`DevGroups*` naming, probably as a historical artifact. This PR updates
the naming.
This includes renaming `uv-configuration/src/dev.rs` to
`uv-configuration/src/dependency_groups.rs`.

## Summary
Follow on to #11706. In the original PR, I tried to solve the issue by
getting rid of the `ctrlc::set_handler` call. Unfortunately, this didn't
work on windows due to an issue with the console crate. console 0.15.11
includes https://github.com/console-rs/console/pull/235, which resolves
the issue, so now we can get rid of the call.
<!-- What's the purpose of the change? What does it do, and why? -->
This change is not super important but I still think it's worthwhile.
For one, spinning up a background thread to handle `SIGINT`s when we're
going to be raising the `SIGINT` from within the function is more
technical complexity than needed, now that there's an easy way to
explicitly catch the Ctrl-C from the terminal input. Secondly,
`ctrlc::set_handler`'s
[docs](https://docs.rs/ctrlc/3.4.5/ctrlc/fn.set_handler.html) advise
that you set the handler just once, at the beginning of the program, so
this use seems somewhat error prone. In fact, uv already has a second
[callsite](461f4d9007/crates/uv/src/commands/project/add.rs (L596-L611))
for this function (though I'm not sure if the two callsites could
currently ever both occur on the same run of uv)
## Test Plan
I've tested this manually on linux (WSL ubuntu) and windows, though not
on aarch64-apple-darwin as I don't have a machine running that. I would
appreciate if someone would double-check that it works on such machines.
As discussed in the original PR, this change is pretty hard to test due
to the fact that the behavior only occurs if stderr is connected to a
tty. I experimented with using pseudoterminals to test this but it's
still quite tricky due to the lack of x-platform non-blocking reads on
the pty.
<!-- How was it tested? -->
Fixes#11217
By default, a 64-bit uv does not see a 32-bit global (HKLM) installation
of Python in the registry
(https://github.com/astral-sh/uv/issues/11217). To work around this, we
manually request both 32-bit and 64-bit access using registry access
flags (https://peps.python.org/pep-0514/#sample-code). The flags have no
effect on 32-bit (https://stackoverflow.com/a/12796797/3549270).
This effect is that there is an asymmetry between discovery modes: For
the registry-based discovery using PEP 514, we discover both 32-bit and
64-bit Pythons, while for managed installations, we are stricter and
only discover those matching in bit-ness.
I tested this manually with an additional 32-bit installation of CPython
on a 64-bit machine and windows with 32-bit and 64-bit (x86_64 and i686)
builds of uv.
Three edition 2021 compatible sets of changes in preparation for the
edition 2025 split out from #11724.
In edition 2025, `gen` is a keyword, so we escape it as `r#gen`. `ref`
and `ref mut` are not allowed anymore for `&T` and `&mut T`, so we
remove them. `cargo fmt` now formats inside of macros, which the 2021
formatter doesn't undo.
## Summary
Testing with `UV_PYTHON_INSTALL_DIR` environment variable has some
problems. This PR fix them.
- `UV_PYTHON_INSTALL_DIR` must be an absolute path.
- Cargo tries to find Python executables from each crates in test. If it
is relative path, cargo searches in different directories for each
tests.
- Skip the test asserting help messages.
- Clap shows the current value of the environment variables. If
`UV_PYTHON_INSTALL_DIR` is set, the test fails.
## Test Plan
<!-- How was it tested? -->
All tests pass with
`UV_PYTHON_INSTALL_DIR=/path/to/my/home/uv/target/testpython`.
## Summary
In. https://github.com/astral-sh/uv/issues/11857, we had a case of a
user that was seeing incorrect resolution results after upgrading to a
newer version of macOS, since we retained cache information about the
interpreter. This PR adds the OS name and version to the cache key for
the interpreter. This seems to be extremely cheap, and it's nice to make
this robust so that users don't run into the same confusion in the
future.
Closes https://github.com/astral-sh/uv/issues/11857.
## Summary
We need to decouple the "Is this shell supported by `update-shell`?"
logic from the "Does this shell have known configuration files?" logic,
specifically for Windows, which we can always update but not via
configuration files.
Closes https://github.com/astral-sh/uv/issues/11803.
## Summary
We use a similar strategy to the ephemeral overlay: set
`include-system-site-packages` in the `pyvenv.cfg`, and clear it
whenever we access a new environment.
Closes https://github.com/astral-sh/uv/issues/11829.
## Test Plan
Difficult to test because we don't really have support for system
packages in our test infrastructure. But...

Reworks how log verbosity flags work.
* `<no argument>` is the same, equivalent to `RUST_LOG=off`
* `-v` is the same, equivalent to `RUST_LOG=uv=debug`
* `-vv` is now equivalent to `RUST_LOG=uv=trace` (previously it only
enabled more log message context)
* `-vvv` is now equivalent to `RUST_LOG=trace` (previously it was
equivalent to `-vv`)
The "more context" that `-vv` had has been moved to an orthogonal
setting via an environment variable. Setting `UV_LOG_CONTEXT=1` will add
the extra context that `-vv` did.
In the future we may make these more granular as we try to use
`info!/warn!` more.

On Windows, trying to read a file inside what is not a directory but
another file results in a not found error, while on Unix we get a not a
directory error. We check explicitly if something included in a
workspace glob is a non-directory to fix the behavior on Windows.
Three network settings are always passed together (though in random
method parameter orders). I factored these out into a struct to make planned future
changes easier.

## Summary
This pull request introduces validation for unique index names in the
`tool.uv.index` field and adds corresponding tests to ensure the
functionality. The most important changes include adding a custom
deserializer function, updating the `ToolUv` struct to use the new
deserializer, and adding tests to verify the behavior.
Validation and deserialization:
*
[`crates/uv-workspace/src/pyproject.rs`](diffhunk://#diff-e12cd255985adfd45ab06f398cb420d2f543841ccbeea4175ccf827aa9215b9dR283-R311):
Added a custom deserializer function `deserialize_index_vec` to validate
that index names in the `tool.uv.index` field are unique.
*
[`crates/uv-workspace/src/pyproject.rs`](diffhunk://#diff-e12cd255985adfd45ab06f398cb420d2f543841ccbeea4175ccf827aa9215b9dR374):
Updated the `ToolUv` struct to use the `deserialize_index_vec` function
for the `index` field.
Testing:
*
[`crates/uv/tests/it/lock.rs`](diffhunk://#diff-82edd36151736f44055f699a34c8b19a63ffc4cf3c86bf5fb34d69f8ac88a957R15336):
Added a test `lock_repeat_named_index` to verify that duplicate index
names result in an error.

Added a test `lock_unique_named_index` to verify that unique index names
result in successful lock file generation.
Schema update:

Updated the schema to set the default value of the `index` field to
`null`.
Fixes#11804
## Test Plan
### Steps to reproduce and verify the fix:
1. Clone the repository and checkout the feature branch
```bash
git clone https://github.com/astral-sh/uv.git
cd uv
git checkout feature/warn-duplicate-index-names
```
2. Build the modified binary
```bash
cargo build
```
3. Create a test project using the system installed uv
```bash
uv init uv-test
cd uv-test
```
4. Manually edit pyproject.toml to add duplicate index names
```toml
[[tool.uv.index]]
name = "alpha_b"
url = "<omitted>"
[[tool.uv.index]]
name = "alpha_b"
url = "<omitted>"
```
5. Try to add a package using the modified binary
```bash
../target/debug/uv add numpy
```
### Results
Before: use release binary

After: use self build binary

Now when attempting to use a pyproject.toml with duplicate index names,
the modified binary correctly detects the issue and produces an error
message:
```
error: Failed to parse: `pyproject.toml`
Caused by: TOML parse error at line 9, column 1
|
9 | [[tool.uv.index]]
| ^^^^^^^^^^^^^^^^^
duplicate index name `alpha_b`
```

## Summary
Follow up for https://github.com/astral-sh/uv/pull/11738
I missed this while reviewing the truncation changes.
`format!("{:.N}", value)` only truncates if the `fmt::Display`
implementation supports it (by reading `f.precision()` in trait
implementation).
So in our case `format!("{:.N}", version.to_string())` will work but not
`format!("{:.N}", version)` unless `Version` supports it.
Since we only need it once, I am just truncating after the string is
created.

## Summary
Closes#2410
<!-- What's the purpose of the change? What does it do, and why? -->
This changes the name of files in `wheels` bucket to use a hash instead
of the wheel name as to not exceed maximum file length limit on various
systems.
This only addresses the primary concern of #2410. It still does _not_
address:
- Path limit of 260 on windows:
https://github.com/astral-sh/uv/issues/2410#issuecomment-2062020882
To solve this we need to opt-in to longer path limits on windows
([ref](https://github.com/astral-sh/uv/issues/2410#issuecomment-2150532658)),
but I think that is a separate issue and should be a separate MR.
- Exceeding filename limit while building a wheel from source
distribution
As per my understanding, this is out of uv's control. Name of the output
wheel will be decided by build-backend used by the project. For wheels
built from source distribution, pip also uses the wheel names in cache.
So I have not touched `sdists` cache.
I have added a `filename: WheelFileName` field in `Archive`, so we can
use it while indexing instead of relying on the filename on disk.
Another way to do this was to read `.dist-info/WHEEL` and
`.dist-info/METADATA` and build `WheelFileName` but that seems less
robust and will be slower.
## Test Plan
<!-- How was it tested? -->
Tested by installing `yt-dlp`, `httpie` and `sqlalchemy` and verifying
that cache files in `wheels` bucket use hash.

Currently, we're using both the official `windows-*` with
`windows-registry` crates as well as `winreg`, an older,
community-maintained crate.
To unify the codebase, we follow the lead of rustup that already
performed this migration
(bce3ed67d2).
This is also a prerequisite to unblock the unification of the
windows-sys crate versions.
I've manually tested that `uv tool update-shell` works for adding to
PATH and correctly detects when PATH was already added.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Resolves#11704
Propagate errors from `uv_console::confirm` up instead of `unwrap`ping
them, causing panics.
## Test Plan
<!-- How was it tested? -->
Regression testing the bug is very difficult, as the behavior of
`confirm` changes based on whether `uv` is talking to a `tty`. We can
trick it using ptys, but the best rust pty crate I could find only
provides blocking reads of the spawned child, which is insufficient to
write the regression test.

## Summary
The animation shadows any interactive authentication prompt which may
occur when resolving dependencies of private repos.
Fixes https://github.com/astral-sh/uv/issues/5107.
## Test Plan
I started creating `install_git_private_https_interactive` as a
regression test but am unsure how to test this because it is interactive
and I don't really know the test framework
## Summary
This is the pattern I see in a variety of crates, and I believe this is
preferred if you don't _need_ an owned `String`, since you can avoid the
allocation. This could be pretty impactful for us?
## Summary
Since we use `SmallString` internally, there's no benefit to passing an
owned string to the `PackageName` constructor (same goes for
`ExtraName`, etc.). I've kept them for now (maybe that will change in
the future, so it's useful to have clients passed own values if they
_can_), but removed a bunch of usages where we were casting from `&str`
to `String` needlessly to use the constructor.

## Summary
I noticed that when running "uv build --all-packages" in an empty
workspace with no buildable packages, it reports that there are
buildable packages. Which I believe to be an error in the message. This
patch fixes the typo. I did not find any relevant issues.
## Test Plan
I've verified, to the best of my ability, that this did not introduce
any additional errors in related existing tests. Considering the nature
of the change I believe it's sufficient.
## Summary
Like `uv add --script`, `uv lock --script` will now initialize a PEP 723
script tag if it doesn't already exist.

## Summary
* Upgrade the rust toolchain to 1.85.0. This does not increase the MSRV.
* Update windows trampoline to 1.86 nightly beta (previously in 1.85
nightly beta).
## Test Plan
Existing tests
## Summary
Likely not critical since these tend to run prior to resolution rather
than in parallel with it, but we _should_ respect in-flight requests
here.
According to the [UV
documentation](https://docs.astral.sh/uv/configuration/files/#env), the
UV_ENV_FILE environment variable should support multiple .env files,
separated by spaces. However, when I tried using this feature in my
repository, it didn’t work as expected.
To investigate, I checked the UV repository for relevant tests and found
`run_with_multiple_env_files`.
This test asserts the following `error: No environment file found at:
.env1 .env2.`
This discrepancy could indicate either a mismatch between the
documentation and the implementation or a bug in the code.
I decided to fix the issue in the code since the ability to pass
multiple `.env` files is a valuable feature.
If my fix isn’t appropriate, I’d be happy to make any necessary
adjustments.

## Summary
I believe these are not necessary... They're currently used in two
places:
1. When building wheels. But that's already wrapped in an in-flight map,
which does the same thing.
2. When fetching source distribution metadata. But every route there
uses it's own `flock` to coordinate across processes, so this seems
redundant?
In #6827, we switched the uv-dev binary to not being built by default.
As an unintended side effect, we were also stopping to run the tests
that ensured the schema was up-to-date.
To fix this, we split uv-dev into an unconditional library, with only
the binary being a conditional build. This way, `cargo test` and `cargo
nextest` pick those tests up again.
An alternative would be running tests with the `dev` feature, with the
side effect of always building the uv-dev binary, too.
## Summary
As-is, we used the refined interpreter to _resolve_, but we then created
the tool environment with the "old" interpreter. So we risked running
(e.g.) code that requires Python 3.12 in a Python 3.10 environment. We
need to propagate the updated interpreter.
This is fairly hard to test, because it requires an environment in which
we're able to download new interpreters.
Closes
https://github.com/astral-sh/uv/issues/11678#issuecomment-2672659074.
Currently, `uv tool list --show-paths` will show backslashes as path
separators for packages but not entrypoints. This PR changes this to be
consistent.
Closes#10426.
## Summary
Today, if you have a lockfile that includes conflict markers, we write
those markers out to `requirements.txt` in `uv export`. This is
problematic, since no tool will ever evaluate those markers correctly
downstream.
This PR adds handling for the conflict markers, though it's quite
involved. Specifically, we have a new reachability algorithm that
tracks, for each node, the reachable marker for that node _and_ the
marker conditions under which each conflict item is `true` (at that
node).
I'm slightly worried that this algorithm could be wrong for graphs with
cycles, but we only use this logic for lockfiles with conflicts anyway,
so I think it's a strict improvement over the status quo.

## Summary
We need to compute the set of activated groups prior to evaluating the
conflict markers on the groups' dependencies.

Solving spent a chunk of its time just converting resolutions, the left
two blocks:

These blocks are `ResolverOutput::from_state` with 1.3% and
`ForkState::into_resolution` with 4.1% of resolver thread runtime for
apache airflow universal.
We reduce the overhead spent in those functions, to now 1.1% and 2.1% of
resolver time spend in those functions by:
Commit 1: Replace the hash set for the edges with a vec in
`ForkState::into_resolution`. We deduplicate edges anyway when
collecting them, and the hash-and-insert was slow.
Commit 2: Reduce the distribution clonign in
`ResolverOutput::from_state` by using an `Arc`.
The same profile excerpt for the resolver with the branch (note that
there is now an unrelated block between the two we optimized):

Wall times are noisy, but the profiles show those changes as
improvements.

Instead of always using all available threads for bytecode compilation,
respect `UV_CONCURRENT_INSTALLS`, so the parallelism is configurable
instead of hardcoded. We reuse the install limit since bytecode
compilation only runs after install.
Revert #11601 for now
We run Python interpreter discovery with `-I` (#2500) which means these
environments variables are ignored when determining `sys.path`. Unless
we decide to remove the `-I` flag from the `sys.path` query, we
shouldn't release these changes to interpreter discovery caching.
I noticed that the latest two `sync-python-releases` jobs failed due to
`httpx.RemoteProtocolError: peer closed connection without sending
complete message body (incomplete chunked read)`.
For the current python-build-standalone release, each request page
(defaulting to 30 items per page) takes about 20 seconds and loads
around 32MB of data. This extensive data load might be causing the
request to frequently fail.
In this PR, I reduced number of items per page to 10 and added
`Accept-Encoding: gzip, deflate` to the request header. Now, it takes
about 6 seconds to load, and the compressed response size has been
reduced to 534KB. I hope this would addresses the request failure.
We want to use `sys.path` for package discovery (#2500, #9849). For
that, we need to know the correct value of `sys.path`. `sys.path` is a
runtime-changeable value, which gets influenced from a lot of different
sources: Environment variables, CLI arguments, `.pth` files with
scripting, `sys.path.append()` at runtime, a distributor patching
Python, etc. We cannot capture them all accurately, especially since
it's possible to change `sys.path` mid-execution. Instead, we do a best
effort attempt at matching the user's expectation.
The assumption is that package installation generally happens in venv
site-packages, system/user site-packages (including pypy shipping
packages with std), and `PYTHONPATH`. Specifically, we reuse
`PYTHONPATH` as dedicated way for users to tell uv to include specific
directories in package discovery.
A common way to influence `sys.path` that is not using venvs is setting
`PYTHONPATH`. To support this we're capturing `PYTHONPATH` as part of
the cache invalidation, i.e. we refresh the interpreter metadata if it
changed. For completeness, we're also capturing other environment
variables documented as influencing `sys.path` or other fields in the
interpreter info.
This PR does not include reading registry values for `sys.path`
additions on Windows as documented in
https://docs.python.org/3.11/using/windows.html#finding-modules. It
notably also does not include parsing of python CLI arguments, we only
consider their environment variable versions for package installation
and listing. We could try parsing CLI flags in `uv run python`, but we'd
still miss them when Python is launched indirectly through a script, and
it's more consistent to only consider uv's own arguments and environment
variables, similar to uv's behavior in other places.
This change keeps dependency group keys sorted when adding new ones.
If earlier dependency group keys were not sorted, we just append the new
group key to avoid churn in `pyproject.toml`. See discussion on #11447.
I've added a new snapshot test to capture this case.
Closes#11447.
## Summary
When tests are run downstream, the `COLUMNS` environment variable is
used to force fixed output width and avoid test failures due to
different terminal widths. However, this occasionally causes test
regressions when other tests rely on different output width. Use the
same `COLUMNS` value in CI to ensure consistent output and catch any
regressions.
## Test Plan
It wasn't, it's supposed to be tested by the CI :-).

The particular example I honed in on here was the `e3nn -> sympy 1.13.1`
and `e3nn -> sympy 1.13.3` dependency edges. In particular, while the
former correctly has a conflict marker, the latter's conflict marker was
getting simplified to `true`. This makes the edges trivially
overlapping, and results in both of them getting installed
simultaneously. (A similar problem happens for the `e3nn -> torch`
dependency edges.)
Why does this happen? Well, conflict marker simplification works by
detecting which extras are known to be enabled (and disabled) for each
node in the graph. This ends up being expressed as a set of sets, where
each inner set contains items corresponding to "extras is included" or
"extra is excluded."
The logic then is if _all_ of these sets are satisfied by the conflict
marker on the dependency edge, then this conflict marker can be
simplified by assuming all of the inclusions/exclusions to be true.
In this particular case, we run into an issue where the set of
assumptions discovered for `e3nn` is:
{test[sevennet]}, {}, {~test[m3gnet], ~test[alignn], test[all]}
And the corresponding conflict marker for `e3nn -> sympy 1.13.1` is:
extra == 'extra-4-test-all'
or extra == 'extra-4-test-chgnet'
or (extra != 'extra-4-test-alignn' and extra != 'extra-4-test-m3gnet')
And the conflict marker for `e3nn -> sympy 1.13.3` is:
extra == 'extra-4-test-alignn' or extra == 'extra-4-test-m3gnet'
Evaluating each of the sets above for `sympy 1.13.1`'s conflict
marker results in them all being true. Simplifying in turn results in
the marker being true. For `sympy 1.13.3`, not all of the sets are
satisfied, so this marker is not simplified.
I think the fundamental problem here is that our inferences aren't quite
rich enough to make these logical leaps. In particular, the conflict
marker for `e3nn -> sympy 1.13.3` is not satisfied by _any_ of our sets.
One might therefore conclude that this dependency edge is impossible.
But! The `test[sevennet]` set doesn't actually rule out `test[m3gnet]`
from being included, for example, because there is no conflict. So it is
actually possible for this marker to evaluate to true.
And I think this reveals the problem: for the `e3nn -> sympy 1.13.1`
conflict marker, the inferences don't capture the fact that
`test[sevennet]` _might_ have `test[m3gnet]` enabled, and that would in
turn result in the conflict marker evaluating to `false`. This directly
implies that our simplification here is inappropriate.
It would be nice to revisit how we build our inferences here so that
they are richer and enable us to make correct logical leaps. For now, we
fix this particular bug with a bit of a cop-out: we skip conflict marker
simplification when there are ambiguous dependency edges.
Fixes#11479
The place to look in this snapshot is the `name = "e3nn"` dependency.
Its dependencies on `sympy` and `torch` consist of multiple versions
with overlapping conflict markers. They are getting incorrectly
simplified to `true`.
Initially, we were limiting Git schemes to HTTPS and SSH as only
supported schemes. We lost this validation in #3429. This incidentally
allowed file schemes, which apparently work with Git out of the box.
A caveat for this is that in tool.uv.sources, we parse the git field
always as URL. This caused a problem with #11425: repo = { git =
'c:\path\to\repo', rev = "xxxxx" } was parsed as a URL where c: is the
scheme, causing a bad error message down the line.
This PR:
* Puts Git URL validation back in place. It bans everything but HTTPS,
SSH, and file URLs. This could be a breaking change, if users were using
a git transport protocol were not aware of, even though never
intentionally supported.
* Allows file: URL in Git: This seems to be supported by Git and we were
supporting it albeit unintentionally, so it's reasonable to continue to
support it.
* It does not allow relative paths in the git field in tool.uv.sources.
Absolute file URLs are supported, whether we want relative file URLs for
Git too should be discussed separately.
Closes#3429: We reject the input with a proper error message, while
hinting the user towards file:. If there's still desire for relative
path support, we can keep it open.

This typo wasn't caught because the `($arg:expr, false)` macro branch
was never exercised.
For example, prior to this change, if you add
```
show_settings!(globals, false);
```
below, you'll get a compiler error.
When running `uv pip install .` in a directory with a pyproject.toml
that does not configure a build, we will invoke setuptools and get a

We want to build `uv-build` without depending on the network crates. In
preparation for that, we split uv-git into uv-git and uv-git-types,
where only uv-git depends on reqwest, so that uv-build can use
uv-git-types.
## Summary
This PR fixes a subtle issue arising from our propagation of
preferences. When we resolve a fork, we take the solution from that fork
and mark all the chosen versions as "preferred" as we move on to the
next fork.
In this specific case, the resolver ended up solving a macOS-specific
fork first, which led us to pick `2.6.0` rather than `2.6.0+cpu`. This
in itself is correct; but when we moved on to the next fork, we
preferred `2.6.0` over `2.6.0+cpu`, despite the fact that `2.6.0` _only_
includes macOS wheel, and that branch was focused on Linux.
Now, in preferences, we prefer local variants (if they exist). If the
local variant ends up not working, we'll presumedly backtrack to the
base version anyway.
Closes https://github.com/astral-sh/uv/issues/11406.
## Summary
If the user provides a PEP 508 requirement (e.g., `uvx
change_wheel_version`), then we should us that verbatim for the
executable, rather than normalizing the package name.
Closes https://github.com/astral-sh/uv/issues/11521.
## Summary
This PR revives https://github.com/astral-sh/uv/pull/10017, which might
be viable now that we _don't_ enforce any platforms by default.
The basic idea here is that users can mark certain platforms as required
(empty, by default). When resolving, we ensure that the specified
platforms have wheel coverage, backtracking if not.
For example, to require that we include a version of PyTorch that
supports Intel macOS:
```toml
[project]
name = "project"
version = "0.1.0"
requires-python = ">=3.11"
dependencies = ["torch>1.13"]
[tool.uv]
required-platforms = [
"sys_platform == 'darwin' and platform_machine == 'x86_64'"
]
```
Other than that, the forking is identical to past iterations of this PR.
This would give users a way to resolve the tail of issues in #9711, but
with manual opt-in to supporting specific platforms.
## Summary
This is an alternative to the approach we took in #11063 whereby we
always included `provides-extra` and `requires-dist`, since we needed
some way to differentiate between "no extras" and "lockfile was
generated by a uv version that didn't include extras".
Instead, this PR adds a minor version (called a "revision") to the
lockfile that we can use to indicate support for this feature. While
lockfile version bumps are backwards-incompatible, older uv versions
_can_ read lockfiles with a later revision -- they just won't understand
all the data.
In a future major version bump, we could simplify things and change the
schema to use a (major, minor) format instead of these two separate
fields. But this is the only way to do it that's backwards-compatible
with existing uv versions.

Initially it seemed like `app.py` might be slightly more desirable but
people seem to overwhelmingly favour `main.py` as a good "generic" name.
Fixes#7782
Closes#11285
Closes https://github.com/astral-sh/uv/pull/11437
This changes `-p` from an alias of `--python-version` to `--python`
while retaining backwards compatibility for `--python-version`-like
fallback behavior when the requested version, e.g., `-p 3.12`, cannot be
found.
This was initially implemented with a hidden `--python-legacy` flag
which allows us to special case the short `-p` flag — unlike the
implementation in #11437. However, after further discussion, we decided
the behavior difference between `-p` and `--python` would be confusing
so now `-p` is an alias for `--python` and `--python` is special-cased
when a version is used.
Additionally, we now respect the `UV_PYTHON` environment variable, but
it is ignored when `--python-version` is set. If you want different
`--python-version` and `--python` values, you must do so explicitly. I
considered banning this, but it is valid for e.g. `--python pypy
--python-version 3.12`
Unlike https://github.com/astral-sh/uv/pull/10222, this does not respect
`UV_PYTHON` in `uv python uninstall` (continuing to require an explicit
target there) which I think is simpler and matches our `.python-version`
file behavior.

`uv publish` has not changed for some time, it has [notable production
usage](https://github.com/search?q=%22uv+publish%22&type=code) and there
are no outstanding blockers, it is time to stabilize it with the 0.6
release.
Publishing is only usable through `uv publish`. You need to build source
distributions and wheels ahead of time, usually with `uv build`.
By default, `uv publish` will upload all source distributions and wheels
in the `dist/` folder, ignoring all non-matching filenames. By default,
`uv build` and most other build frontend write their artifacts to
`dist/`. Together, we can build a publish workflow including a smoke
test that all relevant files have actually been included in the wheel:
```
uv build
uv venv
uv pip install --find-links dist ...
uv run smoke_test.py
uv publish
```
There are 3 options supported in configuration files:
- `tool.uv.publish-url`
- `tool.uv.trusted-publishing`
- `tool.uv.check-url`
Options support on the CLI and through environment variables for index
configuration:
```
--index <INDEX>
The name of an index in the configuration to use for publishing [env: UV_PUBLISH_INDEX=]
--publish-url <PUBLISH_URL>
The URL of the upload endpoint (not the index URL) [env: UV_PUBLISH_URL=]
--check-url <CHECK_URL>
Check an index URL for existing files to skip duplicate uploads [env: UV_PUBLISH_CHECK_URL=]
```
There are two ways to configure `uv publish`: Passing options
individually or using the index API.
For the individual options, there `--publish-url` and `--check-url`, and
their configuration counterparts, `tool.uv.publish_url` and
`tool.uv.check_url`. `--publish-url` is named this way to be clearly
different from the simple index URL, since uploading to the index URL
leads to unclear errors, or worse a 200 OK with no effect. While we
intend to keep supporting this configuration, the index API is better
integrated.
In the index API, the user specifies `[[tool.uv.index]]`, with an index
name, the simple index URL and the publish URL. The `publish-url` and
`url` are equivalent to `--publish-url` and `--check-url`. The `url`
being mandatory makes for a better upload behavior (next paragraph).
```toml
[[tool.uv.index]]
name = "pypi"
url = "https://pypi.org/simple"
publish-url = "https://upload.pypi.org/legacy/"
```
A version of a package contains multiple files, for pure-python packages
usually a source distribution and a wheel, for native packages usually
many, larger wheels and a source distributions. Uploads in the not
officially specified Upload API 1.0 are file based: Once you upload a
file, the version is created, even though most files are still missing.
When uploading a series of files fails in the middle (e.g. the CI server
breaks), the release is only half uploaded. For such cases, you want to
re-try the upload. The response of an index when re-uploading a file is
implementation defined. Notably, PyPI accepts uploads of the same file
again with status 200, but rejects uploads of a file with the same name
but different contents with status 400. Other indexes reject all
attempts at re-uploads with different status codes and messages. Twine
handles this with `--skip-existing`, which allows ignoring errors due to
files with the same name as an existing file being uploaded, however
this does also not error when uploading a file with different contents
but the same name, which indicates a problem with the publish pipeline.
To properly solve this, we need the ability to stage releases: Files of
a version are uploaded to a staging area, and only when all files are
uploaded, we atomically publish the release. When an upload breaks or CI
fails, we can discard or overwrite the staging area and try again. This
will only be properly solved by PEP 694 "Upload 2.0 API for Python
Package Indexes", with unclear progress. For local publishing, it would
also be convenient to be able to check which files exist and what their
hashes are from only the publish URL, so files in the `dist/` folder
from a previous release can be ignored.
In the Upload API 1.0, we need to upload transformed METADATA fields
along with the file as form-data. We currently upload only recognized
metadata fields, where we know how to translate the field name to the
form-data name. This means when a user adds unknown, wrong or future-PEP
metadata we miss it. To me best knowledge no index currently verifies
that the form-data and the METADATA file in the wheel match.
Upload API 2.0 will be an entirely new protocol. It is unclear how we
will decide whether to use Upload API 1.0 or Upload API 2.0 once the
latter is released. Upload API 2.0 will remove the need for a check URL.
This means no changes for `--index`, but `--check-url` will be
incompatible with Upload API 2.0.
Options support on the CLI and through environment variables for
authentication:
```
-u, --username <USERNAME>
The username for the upload [env: UV_PUBLISH_USERNAME=]
-p, --password <PASSWORD>
The password for the upload [env: UV_PUBLISH_PASSWORD=]
-t, --token <TOKEN>
The token for the upload [env: UV_PUBLISH_TOKEN=]
--trusted-publishing <TRUSTED_PUBLISHING>
Configure using trusted publishing through GitHub Actions [possible values: automatic, always,
never]
--keyring-provider <KEYRING_PROVIDER>
Attempt to use `keyring` for authentication for remote requirements files [env:
UV_KEYRING_PROVIDER=] [possible values: disabled, subprocess]
```
We need credentials for the publish URL, and we may need credentials for
the check URL.
We support credentials from environment variables, the CLI, the URL, the
keyring, trusted publishing or a prompt.
The username can come from, in order:
- Mutually exclusive:
- `--username` or `UV_PUBLISH_USERNAME`. The CLI option overrides the
environment variable
- The username field in the publish URL
- If `--token` or `UV_PUBLISH_TOKEN` are used, it is `__token__`. The
CLI option overrides the environment variable
- If trusted publishing is available, it is `__token__`
- (We currently do not read the username from the keyring)
- If stderr is a tty, prompt the user
The password can come from, in order:
- Mutually exclusive:
- `--password` or `UV_PUBLISH_PASSWORD`. The CLI option overrides the
environment variable
- The password field in the publish URL
- If `--token` or `UV_PUBLISH_TOKEN` are used, it is the token value.
The CLI option overrides the environment variable
- If the keyring is enabled, the keyring entry for the URL and username
- If trusted publishing is available, the trusted publishing token
- If stderr is a tty, prompt the user
If no credentials are found, we do a final check in the auth middleware
cache and otherwise error without sending the request.
Trusted publishing is only supported in GitHub Actions. By default, we
try to retrieve a token from it in GitHub Actions (`GITHUB_ACTIONS` is
`true`) but continue even it this fails. Trusted publishing can be
forced with `--trusted-publishing always`, to error on misconfiguration,
or deactivated with `--trusted-publishing never`. The option can also be
configured through `tool.uv.trusted-publishing`.
When `--check-url` or `--index` are used, we may need credentials for
the index URL, too. These are handle separately by the same rules as
using the index anywhere else. The `--keyring-provier` option is however
shared between them, turning the keyring on for either turns it on for
both.
As future option, we could read `UV_INDEX_USERNAME` and
`UV_INDEX_PASSWORD` as fallbacks for the publish credentials
(https://github.com/astral-sh/uv/issues/9845). This however would clash
with prompting: When index credentials and upload credentials are not
the same (they usually should be different, since regular uv operations
should have less privileges than publish), we would then instead of
prompting use the wrong credentials from `UV_INDEX_*` and fail.
A major UX problem is that there is no standard for the username when
using a token (or rather, there is no standard for just sending a token
without a username). PyPI uses `__token__`, Cloudsmith used to use your
username or `token`, but now also supports `__token__`
(https://github.com/astral-sh/uv/issues/8221), while Google Cloud
Artifacts always uses `oauth2accesstoken`
(https://github.com/astral-sh/uv/issues/9778). This means the index
documentation may say you're getting a token for authentication, but you
must not use `--token`, you must instead set username and password. This
is something that we can hopefully fix with Upload API 2.0.
An unsolved problem with the keyring is that you it's best practice to
use publish tokens scoped to projects and store tokens in a secure
location such as the keyring, but the keyring saves a single password
per publish URL and username combination. That means that it can't
natively store separate passwords for publishing multiple packages. The
current hack around this is using the package name as query parameter,
e.g. `https://test.pypi.org/legacy/?astral-test-keyring`, as PyPI
ignores this query parameter. This is however only applicable when
publishing locally and not from CI.
Another problem is that the keyring implementation currently relies on
the `keyring` pypi package, which needs to be installed in PATH together
with its plugins and is comparatively slow. This would be improved by
native keyring support (https://github.com/astral-sh/uv/issues/10867),
with the same caveats such as keyring plugins that shared with the
simple index API.
We currently don't upload attestations (PEP 740). Attestations are an
additional field in the form-data, so we should be able to add them
transparently without any changes to the API, unless we want to add a
switch to deactivate even when trusted publishing is used. See also
https://trailofbits.github.io/are-we-pep740-yet/.
Setuptools is writing an invalid combination of Metadata-Version and
used metadata fields in some cases, which PyPI correctly rejects
(https://github.com/astral-sh/uv/issues/9513).
We set a 15min overall timeout since reqwest is missing a write timeout
option (https://github.com/seanmonstar/reqwest/issues/2403).
https://github.com/astral-sh/uv/issues/8641 and
https://github.com/astral-sh/uv/issues/8774: We build artifact checking
in some capacity. This should be done ideally by the build backend or at
latest as part of `uv build`, doing it as part of publish is too late.
Closes#7839
---
Let me know if i missed anything.
We added this to help with resolving some specific packages, and for
parity with Poetry. But in some cases, this metadata is just wrong, and
at the very least it's unreliable.
Closes https://github.com/astral-sh/uv/issues/8989.
Closes#10945.
Instead of using junctions, we can just write files that contain (as the
file contents) the target path. This requires a little more finesse in
that, as readers, we need to know where to expect these. But it also
means we get to avoid junctions, which have led to a variety of
confusing behaviors. Further, `replace_symlink` should now be on atomic
on Windows.
Closes#11263.
We've never bumped the version of this bucket, and we may never do so...
But it's still incorrect for us to omit it from these serialized structs
in the cache. Specifically, these structs include a pointer into the
archive bucket (namely, the ID). But we don't include the bucket
version! So, in theory, we could end up pointing to archives that don't
match the current bucket version expected in the code.
## Summary
Just a logic issue... If we see a dynamic field that isn't `"version"`,
we end up _not_ propagating the fact that `"version"` is also dynamic.
Closes https://github.com/astral-sh/uv/issues/11460.

## Summary
Handle potential infinite recursion if `uv run` recursively invokes `uv
run`. This can happen if the shebang line of a script includes `uv run`,
but does not pass `--script`.
Handled by adding a new environment variable `UV_RUN_RECURSION_DEPTH`,
which contains a counter of the number of times that uv run has been
recursively invoked. If unset, it defaults to zero, and each time uv run
starts a subprocess we increment the counter, erroring if the value is
greater than a configurable (but not currently exposed or documented)
threshold.
Closes https://github.com/astral-sh/uv/issues/11220.
## Test Plan
I've added a snapshot test to `uv/crates/uv/tests/it/run` that tests the
end-to-end recursion detection flow. I've currently made it a unix-only
test because I'm not sure offhand how uv run will interact with shebang
lines on windows.

I tested the reproduction there manually.
I'm a little uncertain about this behavior, it's not true to the spirit
of `--python <dir>` selecting a target environment but this method is
only used to see if an existing environment matches for the purpose of
invalidation in projects and tools where I think we always force a
separate environment anyway?
## Summary
We need to add indexes in the order in which they're respected by the
resolver. Otherwise, we risk writing an index to the `pyproject.toml`
that is canonically equal (but not verbatim equivalent) to the index we
use during resolutin.
Closes https://github.com/astral-sh/uv/issues/11312.
## Summary
The environment is located at a stable path within the cache, based on
the script's absolute path.
If a lockfile exists for the script, then we use our standard lockfile
semantics (i.e., update the lockfile if necessary, etc.); if not, we
just do a `uv pip sync` (roughly).
Example usage:
```
❯ uv init --script hello.py
Initialized script at `hello.py`
❯ uv add --script hello.py requests
Updated `hello.py`
❯ cargo run sync --script hello.py
