## Summary
Fix incomplete value_type attribute for default-groups field in the
ToolUv struct schema definition. The value_type was missing its value,
which should be str | list[str] to reflect that default-groups can
accept either the literal "all" or a list of group names. (#16574)
Resolves https://github.com/astral-sh/uv/issues/16433
When `uv init` infers a project name from the working directory,
directories with characters outside the PEP 503 rules produced the
generic “Not a valid package or extra name” message that didn’t explain
the source of the problem. This change intercepts that failure, reports
whether the current or explicit target directory caused it, and tells
the user to supply an explicit `--name`.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
This PR removes the crate fs2 and updates Rust version to 1.89.
*Why?*
Crate fs2 is unmaintained for a long time now and has unfixed issues.
Especially it doesn't build on AIX, which is the reason I started fixing
it.
*How?*
I removed fs2 and replaced it by std:fs:File methods.
## Test Plan
<!-- How was it tested? -->
- I built it on Windows and AIX only.
- I did not test the artifacts.

## Summary
This is an enhancement that makes the cli flag `--no-sources` an
environment variable - "UV_NO_SOURCES"
Why is this a relevant change?
When working across different environments, in our case remote vs local,
we often have our packages hosted in a artifact registry but when
developing locally we build our packages from github. This results in us
using the uv.tool.sources table quite a bit however this then also
forces us to use `--no-sources` for all our remote work.
This change enables us to set an environment variable once and to never
have to type --no-sources after every uv run command again.
## Test Plan
Expanded on the current --no-sources tests, to test when
UV_NO_SOURCES=true/false the behaviour is the same as the flag.
Additionally ensured that the cli overrides the env variable.

This PR updates the resolver so `build-system` dependency failures
surface prerelease hints even when prerelease selection is fixed. When a
build dependency only has prerelease candidates, or the requested
version explicitly includes a prerelease marker, we now emit a tailored
hint explaining that build environments can’t auto-enable prereleases
and describing how to opt in.

## Summary
This PR adds an `exclude-dependencies` setting that allows users to omit
a dependency during resolution. It's effectively a formalized version of
the `flask ; python_version < '0'` hack that we've suggested to users in
various issues.
Closes#12616.
It's too common to set `FORCE_COLOR` in CI which then breaks consumption
of the token.
This is actually specific to `pyx.dev`, as we print passwords without
coloring.

Improve readability of progress bars by drawing the right portions in
dimmed black instead of dimmed green. This makes it much easier to
distinguish from the left (finished) part, which is drawn in green.

The `home_dir` function in std was deprecated for some years for reading
`HOME` on Windows. It has recently been fixed and undeprecated:
https://github.com/rust-lang/rust/pull/132515
Conversely, the Cargo maintainers want us to move away from the home
crate (https://github.com/rust-lang/cargo/tree/master/crates/home):
> Note: This has been fixed in Rust 1.85 to no longer use the HOME
environment variable on Windows. If you are still using this crate for
the purpose of getting a home directory, you are strongly encouraged to
switch to using the standard library's home_dir instead. It is planned
to have the deprecation notice removed in 1.87.
>
> This crate further provides two functions, cargo_home and rustup_home,
which are the canonical way to determine the location that Cargo and
rustup store their data.
>
> See rust-lang/rust#43321.
>
> > This crate is maintained by the Cargo team, primarily for use by
Cargo and Rustup and not intended for external use. This crate may make
major changes to its APIs or be deprecated without warning.
When https://github.com/lunacookies/etcetera/pull/36 merges, we can
remove the home crate from our dependency tree.
## Summary
Extend the existing GitHub Gist URL support from #15058 to handle URLs
that redirect to Gists.
`reqwest` already handled generic URL redirects for us (note this
redirects directly to the `.py` on `gist.githubusercontent.com`):
~/git/uv $ uv run
c28a4bf0cb/hello.py
hello world!
But running a URL that redirected to a Gist's "main page" (a bit.ly link
leading to a Gist, etc.) did not:
~/git/uv $ uv run
https://httpbin.org/redirect-to?url=https://gist.github.com/twilligon/4d878a4d9550a4f1df258cde1f058699
File "/tmp/scriptNodt3Q.py", line 87
<title>hello.py · GitHub</title>
But if we have `reqwest` follow redirects *before* `resolve_gist_url`,
we can handle this fine:
~/git/uv $ target/debug/uv run
https://httpbin.org/redirect-to?url=https://gist.github.com/twilligon/4d878a4d9550a4f1df258cde1f058699
hello world!
## Test Plan
I'd write an automated test but that'd require network access since
wiremock doesn't seem to support mocking specific hostnames like
`gist.github.com`. As manual tests go, I basically did the above,
testing with several redirectors to both generic and Gist URLs.
## Summary
Without this, a user who does `uv auth login ...` will retry against the
service's status endpoint forever. This probably isn't what they
intended (they probably walked away from their machine), so we end their
login initiation session after 60 retries. Since we do a retry every
second, this gives them no less than a minute to complete a login (which
should be more than enough).
## Test Plan
We don't have browser-negotiated login tests at the moment in CI, but
I've tested this locally:
```console
% ./target/debug/uv auth login pyx.dev
Logging in with https://api.pyx.dev/auth/cli/login/REDACTED
error: Login session timed out
```
(That took well over a minute, so 60s is a lower bound assuming a very
optimal network roundtrip on each poll.)

When `--system` is used, the debug log now reports interpreter discovery
sources in the same order they are probed, prioritising the PATH ahead
of managed installs on every platform. I also added a few unit tests
that use `DiscoveryPreferences::sources`, ensuring the log strings stay
aligned with the actual discovery sequence for both System and
OnlySystem preferences.
## Summary
Changes the `length` parameter to `PythonDownloadReporter::new` to an
`Option<u64>` to resolve the issue of setting a single-item reporter
length.

## Summary
Upgrades to the latest Rust edition and pyo3 version.
Change initialized module to "Inline Declaration" format.
https://pyo3.rs/v0.27.1/module.html#inline-declaration
The output of `maturin new` is also updating to the new declarative
format
342239a95a
## Test Plan
Updated the relevant snapshot tests and to confirm ran
`cargo nextest run --all-features --no-fail-fast maturin`
Also used the updated template to generate a library in a different
project with
```
cargo run -- init --lib --build-backend maturin --name try-template ../_OTHER_PROJECT_/backend/try-template
```
and the generated workspace member functioned as expected.
Made to address this comment:

This PR sorts the distributions collected by
`FlatIndexClient::read_from_directory` (used for `--find-links`) so
results are ordered deterministically by filename and index.
Closes https://github.com/astral-sh/uv/issues/16218
This occurs when using a mounted file system in Docker.
We're almost always removing a virtual environment to replace it, and
removing the parent directory isn't necessary for that.
Provide a good error message when the discovered workspace members
mismatch with the locked workspace members in `uv export --frozen`,
instead of panicking.
Fixes#16406
I had some qualms with https://github.com/astral-sh/uv/pull/16318
1. The snapshot was specific to uv's managed interpreter due to
inclusion of the externally-managed output. This will break downstream
distros. We either need to filter the message, or, as done here, install
a managed interpreter.
2. It had a custom filter for the interpreter path, which we shouldn't
need. If needed, we should fix that in the test context.
3. We already had an implicit hint to create a virtual environment. The
change in styling of the new hint hint following it is confusing. It's
also confusing to hint creating a virtual environment when `--system`
was used.
4. There were unresolved requested changes to the language for the
message / it didn't fit stylistic with our existing ones.
5. The message was also very confusing for a uv-managed interpreter,
which is both a "system" Python interpreter (in that it's global) and
the opposite of a "system" interpreter per UV_PYTHON_PREFERENCE.
Also problematic, but not addressed here, is that there are other
commands that display an externally-managed message, e.g., `uv pip
sync`, but #16318 was just limited to `pip install`. We should not just
implement this in one place — I'll open a tracking issue to consolidate
and reuse the logic.
Hello,
# Summary
This PR fixes the confusing error message when running `uv lock --check`
with an outdated lockfile.
Previously, the error message incorrectly stated that `--locked` was
provided, even when the user used `--check`.
Now, the error message correctly indicates which flag was used: either
`--check` or `--locked`.
This closes#14105.
# Test plan
- I updated the existing integration test (`check_outdated_lock` in
`lock.rs`) to verify the new error message includes the correct flag.
- I ran existing tests to ensure I have no introduced regressions for
other commands.

Hello,
# Summary
This PR makes the error message clearer when you try to install packages
into an externally managed Python environment with the `--system` flag.
Now, instead of just failing, the error explains that you're hitting
this because you explicitly used `--system`.
This closes#15639.
# Test plan
- I added a new integration test (`install_with_system_interpreter` in
`pip_install.rs`) that checks the error message includes the hint.
- I tried to run `uv pip install --system -r requirements.txt` to see
the actual error message in action, but had permission issues.
Fixes#16340
## Summary
Some package registries (PyTorch, corporate PyPI mirrors) return `403
Forbidden` when a package is not found, instead of `404 Not Found`. The
previous error message incorrectly suggested this was always an
authentication issue, causing confusion for users.
This PR updates the error hint to clarify that a 403 error could
indicate either missing authentication credentials OR that the package
doesn't exist on the index.
## Test Plan
- Updated existing snapshot test in `crates/uv/tests/it/edit.rs` to
reflect the new error message
- The change is purely a message improvement with no behavioral changes
## Changes
### Before
hint: An index URL (https://example.com/simple) could not be queried due
to a lack of valid authentication credentials (403 Forbidden).
### After
hint: An index URL (https://example.com/simple) returned a 403 Forbidden
error. This could indicate missing authentication credentials, or the
package may not exist on this index.
## Files Changed
- `crates/uv-resolver/src/pubgrub/report.rs` - Updated error message
- `crates/uv/tests/it/edit.rs` - Updated snapshot test expectation

[#14386](https://github.com/astral-sh/uv/pull/14386).
On Windows, detection is implemented by querying the
`Win32_VideoController` class via the [WMI
crate](https://github.com/ohadravid/wmi-rs/tree/v0.16.0).
Currently, Intel GPUs (XPU) do not depend on specific driver or toolkit
versions to determine which PyTorch wheel to use.

## Summary
HTTP1.1 [RFC 9112 -
HTTP/1.1](https://www.rfc-editor.org/rfc/rfc9112.html#name-status-line)
section 4 defines the response status code to optionally include a text
description (human readable) of the reason for the status code.
[RFC9113 - HTTP/2](https://www.rfc-editor.org/rfc/rfc9113) is the HTTP2
protocol standard and the response status only considers the [status
code](https://www.rfc-editor.org/rfc/rfc9113#name-response-pseudo-header-fiel)
and not the reason phrase, and as such important information can be lost
in helping the client determine a route cause of a failure.
As per discussion on this
[PR](https://github.com/astral-sh/uv/pull/15979) the current feeling is
that implementing the RFC9457 standard might be the preferred route.
This PR makes those changes to aid the discussion which has also been
moved to the [PEP
board](https://discuss.python.org/t/block-download-of-components-when-violating-policy/104021/1)
## Test Plan
Pulling components that violate our policy over HTTP2 and without any
RFC9457 implementation the following message is presented to the user:

src="https://github.com/user-attachments/assets/0afcd0d8-ca67-4f94-a6c2-131e3b6d8dcc"
/>
With the RFC9457 standard implemented, below you can see the advantage
in the extra context as to why the component has been blocked:

## Summary
Adds the version for environment variables added in
https://github.com/astral-sh/uv/pull/16040 and
https://github.com/astral-sh/uv/pull/16125. as these were in-flight
before documentation versioning was added.
Adds ability to emit a compiler error when added in is missing for
improved reporting to the developer.
e.g. example for the ones fixed in this PR
```shell
error: missing #[attr_added_in("x.y.z")] on `UV_UPLOAD_HTTP_TIMEOUT`
note: env vars for an upcoming release should be annotated with `#[attr_added_in("next release")]`
--> crates\uv-static\src\env_vars.rs:593:15
|
593 | pub const UV_UPLOAD_HTTP_TIMEOUT: &'static str = "UV_UPLOAD_HTTP_TIMEOUT";
| ^^^^^^^^^^^^^^^^^^^^^^
error: missing #[attr_added_in("x.y.z")] on `UV_WORKING_DIRECTORY`
note: env vars for an upcoming release should be annotated with `#[attr_added_in("next release")]`
--> crates\uv-static\src\env_vars.rs:1087:15
|
1087 | pub const UV_WORKING_DIRECTORY: &'static str = "UV_WORKING_DIRECTORY";
| ^^^^^^^^^^^^^^^^^^^^
error: could not compile `uv-static` (lib) due to 2 previous errors
```
Cargo is currently recompiling uv-python on every invocation because the
minified JSON output file is getting a mod time newer than the last run.
Instead, set the mod time of the output file to the same as the input
file.

`pylock.toml` as an input to `uv pip install`,
the error messages are not currently correct.

Relates https://github.com/astral-sh/uv/issues/14720
## Test Plan
Tests with existing tests
I think this is ostensively breaking, though I think the impact would be
small given this will go out in 0.9.1 and should only affect people
using pre-release Python versions.
When `3.14.0` is requested (opposed to `3.14`), we treat this as a
request for a final / stable version and ignore pre-releases.
I think this is a fairly clean way to allow users to explicitly request
the stable version.
Closes https://github.com/astral-sh/uv/issues/16175

## Summary
As new environment variables get introduced (e.g. `UV_EDITABLE`) I
thought it would useful to start tracking which release they were
introduced. I think its a common workflow to navigate to the [env var
documentation](https://docs.astral.sh/uv/reference/environment) to know
what the env var for something is but then end up in a situation where
one is using an environment variable with the wrong version of uv and
not notice immediately that its not compatible and therefore ignored.
## Test Plan
Existing tests.
The versions in `since` have all been manually reviewed to the best of
my ability for correctness.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
This pull request enables the `--directory` option to accept environment
variable: `UV_DIRECTORY`
### Motivation
Currently, the `--project` option already supports environment
variables, but --directory does not.
The motivation for this change is the same as for the --project option.
When using this option, it’s likely that the project root and the
directory containing the uv project differ. In such cases, allowing
environment variables makes it easier to avoid repeatedly specifying the
directory in commands or task runners.
### Other PRs
- PR for create `--project` option:
https://github.com/astral-sh/uv/pull/12327
## Test Plan
<!-- How was it tested? -->
### no auto testing
As with the --project option, no auto tests are included for this
change.
This is because the implementation relies on Clap’s built-in attribute
functionality, and testing such behavior would effectively mean testing
a third-party crate, which would be redundant.
As long as the compiler accepts it, things should work as expected.
### testing manually
i tested manually like [previous pull
request](https://github.com/astral-sh/uv/pull/12327)

Hey devs, great tool as always, you're doing amazing work.
## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Adds the following fields to the `[package]` table of `Cargo.toml` files
where they were missing:
```toml
rust-version = { workspace = true }
homepage = { workspace = true }
documentation = { workspace = true }
repository = { workspace = true }
authors = { workspace = true }
license = { workspace = true }
```
Most crates already had these fields, this just aligns the rest for
consistency.
This also resolves the warnings from `cargo-deny` when using `uv` crates
as dependencies in Pixi.
## Test Plan
No tests needed, this only updates metadata.
Pick up python-build-standalone tag 20251007 to add 3.14.0 final
and 3.13.8, and adjust tests.
Also, fix matching version requests with prereleases: `uvx
python@3.14.0rc3` should not be satisfied by 3.14.0 final.

The `uv-python` crate reads the checked-in download metadata to write
out a minified version to be statically included into the binary.
Sometimes, the resulting `download-metadata-minified.json` can go
missing, such as when `uv` is installed via `cargo` as a git source, and
there is an update; `cargo` will do a hard reset on the git repo it
stores in the cache, causing it to be deleted. In these instances, the
`uv-python` crate does not currently re-run its build script, because as
it happens, there was no change to the `download-metadata.json` since it
was last compiled. This causes a build error like:

error: could not compile `uv-python` (lib) due to 1 previous error

This fixes the issue by also adding a `rerun-if-changed` on the
resulting minified JSON file.
Separately, this revision also changes the output directory of the
minified file to the build script's output directory via the `OUT_DIR`
environment variable, so as not to pollute the source code.

`uv tool upgrade` already respects version pins, but when a tool was
installed with an exact version the command quietly becomes a no-op even
though users expect it to upgrade the executable. This change tweaks the
upgrade flow to detect that situation by inspecting the stored receipt
and, whenever the tool stays pinned, emit a concise hint explaining why
the version didn’t move and how to reinstall without the pin.
The message still appears if the run only refreshed supporting packages,
so users aren’t misled by dependency churn that leaves the tool itself
untouched.
I also added an integration test for the scenario end to end by
installing `babel==2.6.0`, attempting an upgrade, and asserting that the
hint is shown alongside the dependency updates.
Closes https://github.com/astral-sh/uv/issues/16112
```
❯ cargo run -q cache clean
Cache is currently in-use, waiting for other uv processes to finish (use `--force` to override)
```
Otherwise, `-v` is required to see we're waiting on a lock.
I'd rather do this than elevate the exclusive lock log message to
something more verbose because this allows us to use a more specific
message as appropriate for the situation. We also previously reduced the
verbosity of arbitrary locks, e.g., see
https://github.com/astral-sh/uv/issues/7489

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Fixes a part of #14720
Add `TRACING_DURATIONS_FILE` to EnvironmentOptions.
## Test Plan
<!-- How was it tested? -->
## Summary
We serialize the index to the lockfile without the username, so if we
compare based on `==` and the user _includes_ the username in their
`pyproject.toml`, the check will always fail.
Closes https://github.com/astral-sh/uv/issues/16076.
Resolves https://github.com/astral-sh/uv/issues/16067
When we build the dependency graph we add an edge per `Requires-Dist`.
If a package publishes multiple marker-guarded requirements (like
pylint’s `dill>=…` for different Python versions), more than one marker
can evaluate to true at runtime, which gives us several edges pointing
to the same installed package node.
To avoid printing the package multiple times, we gather all edges
targeting that node, pass them through a `Cursor`, and aggregate their
requirement details before we print the dependency line. That
aggregation does two things:
1. If any edge carries a URL, we return that URL immediately.
2. Otherwise we merge all version specifiers into one canonical PEP 440
string.
I've added an integration test, namely `cargo test -p uv --test it
--features pypi -- no_duplicate_dependencies_with_markers` exercises the
new snapshot that installs pylint (with the real dill duplication
scenario present in the original issue) and asserts the tree output,
both with and without `--show-version-specifiers`, now shows a single
dill entry with the merged constraint.
## Summary
I don't think it's common for this to matter, but in theory at least
it's important that these are ordered by severity. Otherwise, e.g,
changing the pre-release mode (and then returning early) could mean we
retain the forks when we otherwise shouldn't.
## Summary
This argument has always existed for compatibility, but apparently we
don't respect it. I assume it was unintentionally dropped during a
refactor.

## Summary
If you provide `--refresh` to `uv lock`, we'll now always resolve (even
though it might return the same result). This is also robust to
`--locked` such that `--refresh --locked` will only fail if the lockfile
changes.
Closes https://github.com/astral-sh/uv/issues/15997.
## Summary
This PR enables users to mark a URL as an S3 endpoint, at which point uv
will sign requests to that URL by detecting credentials from the
standard AWS environment variables, configuration files, etc.
Signing is handled by the
[reqsign](https://docs.rs/reqsign/latest/reqsign/) crate, which we can
also use in the future to sign requests for other providers.
We're seeing reports of a regression from
https://github.com/astral-sh/uv/pull/15888 where `--no-cache` causes `uv
run` and `uvx` to fail to spawn a command.
The intent of this code was to allow destructive cache operations
_after_ we'd finished setting up the environment. However, it's unclear
to me that it's safe to run `uv cache clean` during a `uv run` operation
(e.g., `uv run --script` uses an environment in the cache) and, more
importantly, we cannot drop non-persistent caches (e.g., from
`--no-cache`) as they include the environment we're spawning the command
in.
Alternative to #15977 which retains release of the lock — we may want to
consider that approach still but this regression needs to be resolved
quickly.
Closes https://github.com/astral-sh/uv/issues/15989
Closes https://github.com/astral-sh/uv/issues/15987
Closes https://github.com/astral-sh/uv/issues/15967
Turns out if the minor versions matched we returned false from
`is_upgrade_of` instead of continuing to compare prerelease versions.
Closes#15955.
Note: test cases were initially generated by Claude - I tried making
them shorter.

Add an incompatibility that lets pubgrub skip of marker packages when
the base package already has an incompatible version to improve the
error messages (https://github.com/astral-sh/uv/issues/15199).
The change is also a small perf improvement. Overall this should be able
to improve performance in slow cases by avoiding trying proxy package
versions that are impossible anyway, for a (ideally very small cost) for
tracking the additional incompatibility and tracking the base package
for each proxy package.
```

```
This implementation is the basic version: When we see a proxy
`foo{...}>=x,<y` we add a dependency edge `foo{...}>=x,<y` ->
`foo>=x,<y`. There are several way to extend this, which likely help
more with performance than with error messages.
One idea is that if we see `foo{...}>=x,<y` but we already made a
selection for `foo==z` outside that range, we can insert a dependency
`foo{...}!=z` -> `foo!=z`. This avoids trying any version of the proxy
package except the version that matches our previous selection.
Another is that if we see a dependency `foo>=x,<y`, we also add
`foo{...}>=x,y` -> `foo>=x,<y`. This allows backtracking beyond `foo`
immediately if all version of `foo{...}>=x,<y` are incompatible, since
`foo{...}>=x,<y` incompatible -> `foo>=x,<y` incompatible -> the package
that depended of `foo>=x,<y` is incompatible.
The cost for each of these operations is tracking an additional
incompatibility per virtual package. An alternative approach is to only
add the incompatibility lazily, only when we've tried several version of
the virtual package already. This needs to be weighed of with the better
error messages that the incompatibility gives, we unfortunately have
only few large reference examples.
Requires https://github.com/astral-sh/pubgrub/pull/45
Closes https://github.com/astral-sh/uv/issues/15199
Currently, `uv cache clean` and `uv cache prune` can cause crashes in
other uv processes running in parallel by removing their in-use files.
We can solve this by using a shared (read) lock on the cache directory,
while the `uv cache` operations use an exclusive (write) lock. The
drawback is that this is always one extra lock, and that we assume that
all platforms support shared locks.
Once Rust 1.89 fulfills our N-2 policy, we can add support for these
methods in fs_err and switch to
https://doc.rust-lang.org/std/fs/struct.File.html#platform-specific-behavior-2.

## Summary
I'm back again after #14041, this time for `win_arm64`. I [asked a
Windows on ARM
user](https://github.com/getlogbook/logbook/pull/451#issuecomment-3295513650)
what the value of `platform.machine()` is, and it's `ARM64`.
## Test Plan
Updated/added tests
Extends https://github.com/astral-sh/uv/pull/15679
I'm not sure if we want to do this. It is probably _generally_ true, but
I think I'd rather remove the special casing entirely? I think the main
case for this is that it could help prevent regressions from #15679 and
we can remove it in a breaking release?
While investigating https://github.com/astral-sh/uv/pull/15679, I
created an unnamed conda environment and noticed this quality which
allows us to detect that it's not the base environment.
## Summary
I spent time trying to figure out how to support this but came up empty.
It _seems_ like maybe the `DefaultFields` implementation in
`tracing-subscriber` uses debug formatting for fields...? So if you have
a string with ANSI codes, they end up printing as unformatted values? I
even reverted all our custom formatting in `logging.rs` and saw the same
thing.
Closes https://github.com/astral-sh/uv/issues/15840.
## Summary
Fixes issue #15190 where `uv sync --no-sources` fails to switch from
editable to registry package installations. The problem occurred because
the installer's satisfaction check didn't consider the `--no-sources`
flag when determining if an existing editable installation was
compatible with a registry requirement.
## Solution
Modified `RequirementSatisfaction::check()` to reject non-registry
installations when `SourceStrategy::Disabled` and the requirement is
from registry. Added `SourceStrategy` parameter threading through the
entire call chain from commands to the satisfaction check to ensure
consistent behavior between `uv sync --no-sources` and `uv pip install
--no-sources`.

The previous logic does not match the discussion in the original issue
about this feature, nor does it match the comment for the function. I'm
confused because I know this logic is working for some people? I'm
consequently a little wary of making this change. I'm following up with
some additional changes that should ensure this is robust, e.g., #15680

This PR contains two changes: The companion PR to
https://github.com/astral-sh/packse/pull/277, which moderately
simplifies the uv side, and switching to pylock.toml for packse as
dogfooding. These changes can be applied independent from each other.
Since all files, including the vendored build dependencies, are now on
GitHub Pages under the same root, we only need a packse index root URL.

Closes https://github.com/astral-sh/uv/issues/15818
Unfortunately, this is how we perform lookups. We could also change the
lookup to include the scheme. I expect all of this to change in the
future anyway, as I want to redesign the storage model for native
credentials.
## Summary
In the process of making a different change, I noticed that we parse
this during source discovery, throw it away, then parse it again later.
## Summary
If the target for `uv pip compile` is a `pyproject.toml` in a
subdirectory, we won't have loaded the credentials when we go to lower
(since it won't be loaded as part of "configuration discovery"). We now
add those indexes just-in-time.
Closes https://github.com/astral-sh/uv/issues/15362.
## Summary
I had to use ChatGPT to help with my research on the "correct"
architecture names for these platforms; there could still be some rough
edges, but this seems like an improvement.
Closes https://github.com/astral-sh/uv/issues/15799.
## Summary
I think this is leftover from a prior refactor whereby we used to avoid
reusing the cached environment if `--reinstall` was passed; but then we
stopped allowing `--reinstall` in `uv tool run` anyway, and this got
changed to `--refresh`. It seems wrong to skip cache reuse with
`--refresh`, though.
Closes https://github.com/astral-sh/uv/issues/15824.
## Summary
We allow space-delimiting for `--env-file`, but Clap doesn't support any
form of escaping, so as-is, there's no way to provide a `.env` file in a
directory that contains a space. We now do the splitting ourselves and
respect escapes.
Closes https://github.com/astral-sh/uv/issues/15806.
## Summary
Right now, we only list changes if the _version_ differs. This PR takes
the SHA into account. We may want to list changes to _any_ sources, but
that gets more complicated (e.g., if the user swaps the index URL, we'd
have to show _all_ changes to the index URL).
Closes#15810.

## Summary
This change extends the default initialized projects with scikit and
maturin build backends to ensure that the rust or C++ build gets invoked
when a source file changes.
## Test Plan
`cargo run init cppextension-test --build-backend=scikit` followed by
manual testing of the behaviour of the resulting project under `uv run
--with jupyter jupyter lab` and changes to the source file of the
extension.
Analogous for `cargo run init maturin-test --build-backend=maturin `.
## Relevant Issues
The question of why the python extension is not rebuilt on source
changes has been discussed in
https://github.com/astral-sh/uv/issues/15701#issuecomment-3258714942.

## Summary
- Added `conflicts_with = "only_group"` to `--extra` arguments in
`SyncArgs`, `RunArgs`, and `ExportArgs`
- Added tests to verify proper conflict detection and error messages
**Before:** The `--extra` flag was silently ignored when used with
`--only-group`
**After:** Clear error message: `error: the argument '--only-group
<ONLY_GROUP>' cannot be used with '--extra <EXTRA>'`
fixes: #15676
## Test Plan
- Tests confirm proper error message format when `--only-group` and
`--extra` are used together
- Verified existing functionality remains unchanged when flags are used
independently
## Summary
If the user explicitly authenticated to pyx, then we attempt to use the
pyx PyTorch URLs; otherwise, we stick to `download.pytorch.org` as the
default.
## Summary
Ignore managed pre-release versions of Python for purposes of creating a
`requires-python` constraint when running `uv init --script`. This makes
the behavior consistent with `uv init` for normal projects.
## Test Plan
Added a regression test that makes sure that the constraint is
`requires-python = ">=3.13"`, even though a pre-release version of 3.14
is installed.
Consistently omit backticks after a colon in build backend messages,

but this PR clears all matches in the build backend.
