Our current strategy of parsing the output of `py --list-paths` to get
the installed python versions on windows is brittle (#6524, missing
`py`, etc.) and it's slow (10ms last time i measured).
Instead, we should behave spec-compliant and read the python versions
from the registry following PEP 514.
It's not fully clear which errors we should ignore and which ones we
need to raise.
We're using the official rust-for-windows crates for accessing the
registry.
Fixes#1521Fixes#6524
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
We now respect the user-provided upper-bound in for `requires-python`.
So, if the user has `requires-python = "==3.11.*"`, we won't explore
forks that have `python_version >= '3.12'`, for example.
However, we continue to _only_ compare the lower bounds when assessing
whether a dependency is compatible with a given Python range.
Closes https://github.com/astral-sh/uv/issues/6150.
Previously, we were always asking Cargo to rebuild `uv-cli` if
`.git/HEAD` had changed. But in a worktree, `.git` is a file, not a
directory. And the file contains the path to git's internal worktree
state, which also has its own `HEAD` file. So in the case of a worktree,
we read the file and tell Cargo to watch the worktree-specific `HEAD`
file instead of `.git/head`.
The main thing this fixes is that, previously, in a worktree, `cargo
build` would *always* re-compile `uv` even if nothing changed.
This doesn't impact or fix anything in "typical" clones of uv though.
Only in worktrees.
Closes#6196, Closes#6197
## Summary
The interface here is intentionally a bit more limited than `uv pip
compile`, because we don't want `requirements.txt` to be a system of
record -- it's just an export format. So, we don't write annotation
comments (i.e., which dependency is requested from which), we don't
allow writing extras, etc. It's just a flat list of requirements, with
their markers and hashes.
Closes#6007.
Closes#6668.
Closes#6670.
This is achieved by updating the `LockedFile::acquire` API to be async —
as in some cases we were attempting to acquire the lock synchronously,
i.e., without yielding, which blocked the runtime.
Closes https://github.com/astral-sh/uv/issues/6691 — I tested with the
reproduction there and a local release build and no longer reproduce the
deadlock with these changes.

## Summary
Whether a package is itself virtual isn't captured in the package
metadata, so we have to compare the sources.
Closes https://github.com/astral-sh/uv/issues/6749.
## Summary
If you're in a directory, and there's workspace above it, we check if
the directory is excluded from the workspace members... But not if it's
_included_ in the first place.
Closes https://github.com/astral-sh/uv/issues/6732.
## Summary
Use a dedicated source type for non-package requirements. Also enables
us to support non-package `path` dependencies _and_ removes the need to
have the member `pyproject.toml` files available when we sync _and_
makes it explicit which dependencies are virtual vs. not (as evidenced
by the snapshot changes). All good things!
## Summary
This PR makes `cargo test | windows` faster in CI.
### Before

### After

## Also
This PR disables the `brotli` feature of `async-compression` since it's
not strictly needed, but this has little to do with the improvements
(it's still less code to build).
This PR introduces additional code in uv tool uninstall to ignore errors
(that only seem to happen on ReFS, ie. on Dev Drives) akin to "the thing
we're trying to delete cannot be deleted because it's already being
deleted".
If `raw_os_error` was stable we could do u32 matching instead of that
`.to_string().contains()` abomination.
## Summary
In theory this problem already existed for `PKG-INFO`, but `egg-info`
would be more common, I think, since it's built in the source tree.
Closes https://github.com/astral-sh/uv/issues/6712.
Changes the `uv init` experience with a focus on working for more
use-cases out of the box.
- Adds `--app` and `--lib` options to control the created project style
- Changes the default from a library with `src/` and a build backend
(`--lib`) to an application that is not packaged (`--app`)
- Hides the `--virtual` option and replaces it with `--package` and
`--no-package`
- `--no-package` is not allowed with `--lib` right now, but it could be
in the future once we understand a use-case
- Creates a runnable project
- Applications have a `hello.py` file which you can run with `uv run
hello.py`
- Packaged applications, e.g., `uv init --app --package` create a
package and script entrypoint, which you can run with `uv run hello`
- Libraries provide a demo API function, e.g., `uv run python -c "import
name; print(name.hello())"` — this is unchanged
Closes#6471
## Summary
We were writing empty lines between the dependencies and the
`tool.uv.sources` table, which led to the `/// script` tag being
unclosed and thus not recognized.
Closes https://github.com/astral-sh/uv/issues/6700.
Should this be user-facing by default? It seems annoying because then
it's unavoidable if you (for whatever reason) have an intentionally
unclosed tag.
Motivated by https://github.com/astral-sh/uv/issues/6700.
## Summary
The basic idea here is: any project can either be a package, or not
("virtual").
If a project is virtual, we don't build or install it.
A project is virtual if either of the following are true:
- `tool.uv.virtual = true` is set.
- `[build-system]` is absent.
The concept of "virtual projects" only applies to workspace member right
now; it doesn't apply to `path` dependencies which are treated like
arbitrary Python source trees.
TODOs that should be resolved prior to merging:
- [ ] Documentation
- [ ] How do we reconcile this with "virtual workspace roots" which are
a little different -- they omit `[project]` entirely and don't even have
a name?
- [x] `uv init --virtual` should create a virtual project rather than a
virtual workspace.
- [x] Running `uv sync` in a virtual project after `uv init --virtual`
shows `Audited 0 packages in 0.01ms`, which is awkward. (See:
https://github.com/astral-sh/uv/pull/6588.)
Closes https://github.com/astral-sh/uv/issues/6511.
## Summary
Tries to improve the following:
```
❯ cargo run sync
Compiling uv-cli v0.0.1 (/Users/crmarsh/workspace/uv/crates/uv-cli)
Compiling uv v0.3.3 (/Users/crmarsh/workspace/uv/crates/uv)
Finished `dev` profile [unoptimized + debuginfo] target(s) in 3.81s
Running `/Users/crmarsh/workspace/uv/target/debug/uv sync`
Using Python 3.12.1
Creating virtualenv at: .venv
Resolved in 7ms
Audited environment in 0.05ms
```
In this case we don't actually have any dependencies -- should we just
omit `Resolved in...` and perhaps even the audited line?
## Summary
This PR revives https://github.com/astral-sh/uv/pull/4944, which I think
was a good start towards adding `--trusted-host`. Last night, I tried to
add `--trusted-host` with a custom verifier, but we had to vendor a lot
of `reqwest` code and I eventually hit some private APIs. I'm not
confident that I can implement it correctly with that mechanism, and
since this is security, correctness is the priority.
So, instead, we now use two clients and multiplex between them.
Closes https://github.com/astral-sh/uv/issues/1339.
## Test Plan
Created self-signed certificate, and ran `python3 -m http.server --bind
127.0.0.1 4443 --directory . --certfile cert.pem --keyfile key.pem` from
the packse index directory.
Verified that `cargo run pip install
transitive-yanked-and-unyanked-dependency-a-0abad3b6 --index-url
https://127.0.0.1:8443/simple-html` failed with:
```
error: Request failed after 3 retries
Caused by: error sending request for url (https://127.0.0.1:8443/simple-html/transitive-yanked-and-unyanked-dependency-a-0abad3b6/)
Caused by: client error (Connect)
Caused by: invalid peer certificate: Other(OtherError(CaUsedAsEndEntity))
```
Verified that `cargo run pip install
transitive-yanked-and-unyanked-dependency-a-0abad3b6 --index-url
'https://127.0.0.1:8443/simple-html' --trusted-host '127.0.0.1:8443'`
failed with the expected error (invalid resolution) and made valid
requests.
Verified that `cargo run pip install
transitive-yanked-and-unyanked-dependency-a-0abad3b6 --index-url
'https://127.0.0.1:8443/simple-html' --trusted-host '127.0.0.2' -n` also
failed.
As described in #4242, we're currently incorrectly downloading glibc
python-build-standalone on musl target, but we also can't fix this by
using musl python-build-standalone on musl targets since the musl builds
are effectively broken.
We reintroduce the libc detection previously removed in #2381, using it
to detect which libc is the current one before we have a python
interpreter. I changed the strategy a big to support an empty `PATH`
which we use in the tests.
For simplicity, i've decided to just filter out the musl
python-build-standalone archives from the list of available archive,
given this is temporary. This means we show the same error message as if
we don't have a build for the platform. We could also add a dedicated
error message for musl.
Fixes#4242
## Test Plan
Tested manually.
On my ubuntu host, python downloads continue to pass:
```
target/x86_64-unknown-linux-musl/debug/uv python install
```
On alpine, we fail:
```
$ docker run -it --rm -v .:/io alpine /io/target/x86_64-unknown-linux-musl/debug/uv python install
Searching for Python installations
error: No download found for request: cpython-any-linux-x86_64-musl
```
## Summary
We now respect the `environments` field in `uv pip compile --universal`,
e.g.:
```toml
[tool.uv]
environments = ["platform_system == 'Emscripten'"]
```
Closes https://github.com/astral-sh/uv/issues/6641.
