Enable `lzma-sys/static` through the performance feature not only in uv,
but in uv-dev and uv-bench too, to avoid the system dependency on
`liblzma-dev`.
Ref #9880
Add a preview option `uv init --build-backend uv --preview` that uses
the uv build backend when generating the project. The uv build backend
is in preview, so the option is also guarded by preview and hidden from
the help message and docs.
For https://github.com/astral-sh/uv/issues/3957#issuecomment-2518757563
- Adds a collapsible section for the project concept
- Splits the project concept document into several child documents.
- Moves the workspace and dependencies documents to under the project
section
- Adds a mkdocs plugin for redirects, so links to the moved documents
still work
I attempted to make the minimum required changes to the contents of the
documents here. There is a lot of room for improvement on the content of
each new child document. For review purposes, I want to do that work
separately. I'd prefer if the review focused on this structure and idea
rather than the content of the files.
I expect to do this to other documentation pages that would otherwise be
very nested.
The project concept landing page and nav (collapsed by default) looks
like this now:

## Summary
These were moved as part of a broader refactor to create a single
integration test module. That "single integration test module" did
indeed have a big impact on compile times, which is great! But we aren't
seeing any benefit from moving these tests into their own files (despite
the claim in [this blog
post](https://matklad.github.io/2021/02/27/delete-cargo-integration-tests.html),
I see the same compilation pattern regardless of where the tests are
located). Plus, we don't have many of these, and same-file tests is such
a strong Rust convention.
## Summary
* Env docs now support anchors, which allows sending a link to someone
with a direct reference to an env var or cross-reference them in the
docs.
* Marked additional env vars as hidden from the docs due to their
internal use
* Updates some tests still using literals to use the static env vars

## Summary
Resolves#8417
I've just begun learning procedural macros, so this PR is more of a
proof of concept. It's still a work in progress, and I welcome any
assistance or feedback.
## Summary
For example, in:
```toml
[tool.uv]
[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cu121"
```
We can just omit `[tool.uv]`.
## Summary
This PR declares and documents all environment variables that are used
in one way or another in `uv`, either internally, or externally, or
transitively under a common struct.
I think over time as uv has grown there's been many environment
variables introduced. Its harder to know which ones exists, which ones
are missing, what they're used for, or where are they used across the
code. The docs only documents a handful of them, for others you'd have
to dive into the code and inspect across crates to know which crates
they're used on or where they're relevant.
This PR is a starting attempt to unify them, make it easier to discover
which ones we have, and maybe unlock future posibilities in automating
generating documentation for them.
I think we can split out into multiple structs later to better organize,
but given the high influx of PR's and possibly new environment variables
introduced/re-used, it would be hard to try to organize them all now
into their proper namespaced struct while this is all happening given
merge conflicts and/or keeping up to date.
I don't think this has any impact on performance as they all should
still be inlined, although it may affect local build times on changes to
the environment vars as more crates would likely need a rebuild. Lastly,
some of them are declared but not used in the code, for example those in
`build.rs`. I left them declared because I still think it's useful to at
least have a reference.
Did I miss any? Are their initial docs cohesive?
Note, `uv-static` is a terrible name for a new crate, thoughts? Others
considered `uv-vars`, `uv-consts`.
## Test Plan
Existing tests
As per
https://matklad.github.io/2021/02/27/delete-cargo-integration-tests.html
Before that, there were 91 separate integration tests binary.
(As discussed on Discord — I've done the `uv` crate, there's still a few
more commits coming before this is mergeable, and I want to see how it
performs in CI and locally).

## Summary
Part of https://github.com/astral-sh/uv/issues/7007.
Settings documentation reference currently doesn't separate "project
metadata" and "configuration" options, implying that it's possible to
set things like `dev-dependencies` in `uv.toml` while it's not. This is
an attempt at better separating those options, by having 2 different
sections:
- `Project metadata`, that holds configuration that can only be set in
`pyproject.toml`
- `Configuration`, that holds configuration that can be set both in
`pyproject.toml` and `uv.toml`
Here are some screenshots to show what this looks like (note that I
don't have code highlighting in the right navigation, which makes them
clunky, as first item is always bigger because of the missing "span" --
I think that's because it's an `mkdocs-material` insider feature, since
I have the same thing on `main` branch):
- Right side navigation:

## Summary
We now track the discovered `IndexCapabilities` for each `IndexUrl`. If
we learn that an index doesn't support range requests, we avoid doing
any batch prefetching.
Closes https://github.com/astral-sh/uv/issues/7221.
## Summary
This PR exposes uv's PEP 517 implementation via a `uv build` frontend,
such that you can use `uv build` to build source and binary
distributions (i.e., wheels and sdists) from a given directory.
There are some TODOs that I'll tackle in separate PRs:
- [x] Support building a wheel from a source distribution (rather than
from source) (#6898)
- [x] Stream the build output (#6912)
Closes https://github.com/astral-sh/uv/issues/1510
Closes https://github.com/astral-sh/uv/issues/1663.
Most times we compile with `cargo build`, we don't actually need
`uv-dev`. By making `uv-dev` dependent on a new `dev` feature, it
doesn't get built by default anymore, but only when passing `--features
dev`.
Hopefully a small improvement for compile times or at least system load.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
This changes the behavior a bit of the per-dependency build-isolation
override. That, if the dist name is known, it is passed into the
`SourceBuild::Setup` function. This allows for this override to work for
projects without a `pyproject.toml`, like `detectron2`, using the
specified requirement name. Previously only the `pyproject.toml` name
could be used, which these projects are lacking. An example of a
use-case is given in the *Test Plan* section.
Additionally, the `no_build_isolation_package` has been adding to
`InstallerSettingsRef` and used in `sync` and other commands, as this
was not done yet.
This is useful if you want to **non**-isolate a single package, even
ones without a proper `pyproject.toml`
## Test Plan
<!-- How was it tested? -->
With the following pyproject.toml.
```toml
[project]
name = "detectron-uv"
version = "0.1.0"
description = "Add your description here"
readme = "README.md"
requires-python = ">=3.12"
dependencies = [
"detectron2",
"setuptools",
"torch",
]
[build-system]
requires = ["hatchling"]
build-backend = "hatchling.build"
[tool.uv.sources]
detectron2 = { git = "https://github.com/facebookresearch/detectron2", rev = "bcfd464d0c810f0442d91a349c0f6df945467143" }
[tool.uv]
no-build-isolation-package = ["detectron2"]
```
The package `detectron2` is now correctly **non**-isolated. Before,
because the logic depended on getting the name from the
`pyproject.toml`, which is lacking in detectron2 you would get the
message, that the source could not be built. This was because it would
still be *isolated* in that case.
With these changes you can now install using (given that you are inside
a workspace with a venv):
```
uv pip install torch setuptools
uv sync
```
This would previously fail with something like:
```
error: Failed to prepare distributions

If detectron2 @ git+https://github.com/facebookresearch/detectron2@bcfd464d0c810f0442d91a349c0f6df945467143 is a first-party package, consider adding torch to its `build-system.requires`. Otherwise, `uv pip install torch` into the environment and re-run with `--no-build-isolation`.
```
**Edit**:
Some wording, used isolated where it should be **non**-isolated.
This is a fallback mode that we supported when we decided to use PEP 517
builds by default. I can't find a single reference to it on GitHub or in
our issue tracker, so I want to drop support for it as part of v0.3.0.
- Removes "experimental" labels from command documentation
- Removes preview warnings
- Removes `PreviewMode` from most structs and methods — we could keep it
around but I figure we can propagate it again easily where needed in the
future
- Enables preview behavior by default everywhere, e.g., `uv venv` will
download Python versions
Following #5869, the documentation has some less-than-helpful
suggestions to use `uv help python` for details — we should link to the
`uv python` section instead.
## Summary
Partially resolves#5561. Haven't added overrides support yet but I can
add it tomorrow if the current approach for constraints is ok.
## Test Plan
`cargo test`
Manually checked trace logs after changing the constraints.
## Summary
Move completely off tokio's multi-threaded runtime. We've slowly been
making changes to be smarter about scheduling in various places instead
of depending on tokio's general purpose work-stealing, notably
https://github.com/astral-sh/uv/pull/3627 and
https://github.com/astral-sh/uv/pull/4004. We now no longer benefit from
the multi-threaded runtime, as we run on all I/O on the main thread.
There's one remaining instance of `block_in_place` that can be swapped
for `rayon::spawn`.
This change is a small performance improvement due to removing some
unnecessary overhead of the multi-threaded runtime (e.g. spawning
threads), but nothing major. It also removes some noise from profiles.
## Test Plan
```
Benchmark 1: ./target/profiling/uv (resolve-warm)
Time (mean ± σ): 14.9 ms ± 0.3 ms [User: 3.0 ms, System: 17.3 ms]
Range (min … max): 14.1 ms … 15.8 ms 169 runs
Benchmark 2: ./target/profiling/baseline (resolve-warm)
Time (mean ± σ): 16.1 ms ± 0.3 ms [User: 3.9 ms, System: 18.7 ms]
Range (min … max): 15.1 ms … 17.3 ms 162 runs
Summary
./target/profiling/uv (resolve-warm) ran
1.08 ± 0.03 times faster than ./target/profiling/baseline (resolve-warm)
```
Whew this is a lot.
The user-facing changes are:
- `uv toolchain` to `uv python` e.g. `uv python find`, `uv python
install`, ...
- `UV_TOOLCHAIN_DIR` to` UV_PYTHON_INSTALL_DIR`
- `<UV_STATE_DIR>/toolchains` to `<UV_STATE_DIR>/python` (with
[automatic
migration](https://github.com/astral-sh/uv/pull/4735/files#r1663029330))
- User-facing messages no longer refer to toolchains, instead using
"Python", "Python versions" or "Python installations"
The internal changes are:
- `uv-toolchain` crate to `uv-python`
- `Toolchain` no longer referenced in type names
- Dropped unused `SystemPython` type (previously replaced)
- Clarified the type names for "managed Python installations"
- (more little things)
## Summary
The `--index-strategy` is linked to the index locations, which we
propagate to source distribution builds; so it makes sense to pass the
`--index-strategy` too.
While I was here, I made `exclude_newer` a required argument so that we
don't forget to set it via the `with_options` builder.
Closes https://github.com/astral-sh/uv/issues/4465.
Restores the `PythonEnvironment::find` API which was removed a while
back in favor of `Toolchain::find`. As mentioned in #4416, I'm
attempting to separate the case where you want an active environment
from the case where you want an installed toolchain in order to create
environments.
I wanted to drop `EnvironmentPreference` from `Toolchain::find` and just
have us consistently consider (or not consider) virtual environments
when discovering toolchains for creating environments. Unfortunately
this caused a few things to break so I reverted that change and will
explore it separately. Because I was exploring that change, there are
some minor changes to the `Toolchain` API here.
Adds support for the toolchain discovery preferences outlined in
https://github.com/astral-sh/uv/issues/4198 but we don't expose this to
users yet, I'll do that next to make it easier to review.
I've made some refactors in the toolchain discovery implementation to
enable this behavior and move us towards clearer abstractions. There's
still remaining work here, but I'd prefer tackle things in follow-ups
instead of expanding this pull request. I plan on opening a couple
before merging this.
I'd like to shift the public toolchain API to focus on discovering
either an **environment** or a **toolchain**. The first would be used by
commands that operate on an environment, while the latter would be used
by commands that just need an interpreter to create environments. I
haven't changed this here, but some of the refactors are in preparation
for supporting this idea.
In brief:
- We now allow different ordering of installed toolchain discovery based
on a `ToolchainPreference` type. This is the type we will expose to
users.
- `SystemPython` was changed into an `EnvironmentPreference` which is
used to determine if we should prefer virtual or system Python
environments.
- We drop the whole `ToolchainSources` selection concept, it was
confusing and the error messages from it were awkward. Most of the
functionality is now captured by the preference enums, but you can't do
things like "only find a toolchain from the parent interpreter" as
easily anymore.
