## Summary
This was just an oversight on my part in the initial implementation.
Closes https://github.com/astral-sh/uv/issues/14719.
## Test Plan
With:
```toml
[project]
name = "foo"
version = "0.1.0"
description = "Add your description here"
readme = "README.md"
requires-python = ">=3.13.2"
dependencies = [
]
[[tool.uv.index]]
url = "https://download.pytorch.org/whl/cpu"
cache-control = { api = "max-age=600" }
```
Ran `cargo run lock -vvv` and verified that the PyTorch index response
was cached (whereas it typically returns `cache-control:
no-cache,no-store,must-revalidate`).
With the previous order of operations, there could be warnings from race
conditions between two process A and B removing and installing Python
versions.
* A removes the files for CPython3.9.18
* B sees the key CPython3.9.18
* B sees that CPython3.9.18 has no files
* A removes the key for CPython3.9.18
* B try to removes the key for CPython3.9.18, gets and error that it's
already gone, issues a warning
We make the more resilient in two ways:
* We remove the registry key first, avoiding dangling registry keys in
the removal process
* We ignore not found errors in registry removal operations: If we try
to remove something that's already gone, that's fine.
Fixes#14714 (hopefully)
Reviewing #14687, I noticed that we had implemented a
`Url::from_url_or_path`-like function, but it wasn't reusable. This
change `Verbatim::from_url_or_path` so we can use it in other places
too.
The PEP 508 parser is an odd place for this, but that's where
`VerbatimUrl` and `Scheme` are already living.
We recently ran over the file limit and had to drop hash file from the
releases page in favor of bulk SHA256SUMS files
(https://github.com/astral-sh/python-build-standalone/pull/691).
Conveniently, GitHub has recently started to add a SHA256 digest to the
API. GitHub did not backfill the hashes for the old releases, so use the
API hashes for newer assets, and eventually only download SHA256SUMS for
older releases.
We currently treat path sources as virtual if they do not specify a
build system, which is surprising behavior. This PR updates the behavior
to treat path sources as packages unless the path source is explicitly
marked as `package = false` or its own `tool.uv.package` is set to
`false`.
Closes#12015

By default, `uv venv <venv-name>` currently removes the `<venv-name`>
directory if it exists. This can be surprising behavior: not everyone
expects an existing environment to be overwritten. This PR updates the
default to fail if a non-empty `<venv-name>` directory already exists
and neither `--allow-existing` nor the new `-c/--clear` option is
provided (if a TTY is detected, it prompts first). If it's not a TTY,
then uv will only warn and not fail for now — we'll make this an error
in the future. I've also added a corresponding `UV_VENV_CLEAR` env var.
I've chosen to use `--clear` instead of `--force` for this option
because it is used by the `venv` module and `virtualenv` and will be
familiar to users. I also think its meaning is clearer in this context
than `--force` (which could plausibly mean force overwrite just the
virtual environment files, which is what our current `--allow-existing`
option does).
Closes#1472.

In the case of `uv sync` all we really need to do is handle the
`OutdatedEnvironment` error (precisely the error we yield only on
dry-runs when everything Works but we determine things are outdated) in
`OperationDiagnostic::report` (the post-processor on all
`operations::install` calls) because any diagnostic handled by that gets
downgraded to from status 2 to status 1 (although I don't know if that's
really intentional or a random other bug in our status handling... but I
figured it's best to highlight that other potential status code
incongruence than not rely on it 😄).
Fixes#12603

We weren't following our usual "destructure all the options" pattern in
this function, and several "this isn't actually read from uv.toml"
fields slipped through the cracks over time since folks forgot it
existed.
Fixes part of #14308, although we could still try to make the warning in
FilesystemOptions more accurate?
You could argue this is a breaking change, but I think it ultimately
isn't really, because we were already silently ignoring these fields.
Now we properly error.
If a user specifies `-e /path/to/dir` and `/path/to/dir` in a `uv pip
install` command, we want the editable to "win" (rather than erroring
due to conflicting URLs). Unfortunately, this behavior meant that when
you requested a package as editable and non-editable in conflicting
groups, the editable version was _always_ used. This PR modifies the
requisite types to use `Option<bool>` rather than `bool` for the
`editable` field, so we can determine whether a requirement was
explicitly requested as editable, explicitly requested as non-editable,
or not specified (as in the case of `/path/to/dir` in a
`requirements.txt` file). In the latter case, we allow editables to
override the "unspecified" requirement.
If a project includes a path dependency twice, once with `editable =
true` and once without any `editable` annotation, those are now
considered conflicting URLs, and lead to an error, so I've marked this
change as breaking.
Closes https://github.com/astral-sh/uv/issues/14139.
If `--workspace` is provided, we add all paths as workspace members.
If `--no-workspace` is provided, we add all paths as direct path
dependencies.
If neither is provided, then we add any paths that are under the
workspace root as workspace members, and the rest as direct path
dependencies.
Closes#14524.
While reviewing https://github.com/astral-sh/uv/pull/14107, @oconnor663
pointed out a bug where we allow `uv python pin --rm` to delete the
global pin without the `--global` flag. I think that shouldn't be
allowed? I'm not 100% certain though.
Adds environment variables for
https://github.com/astral-sh/uv/pull/14612 and
https://github.com/astral-sh/uv/pull/14614
We can't use the Clap `BoolishValueParser` here, and the reasoning is a
little hard to explain. If we used `UV_PYTHON_INSTALL_NO_BIN`, as is our
typical pattern, it'd work, but here we allow opt-in to hard errors with
`UV_PYTHON_INSTALL_BIN=1` and I don't think we should have both
`UV_PYTHON_INSTALL_BIN` and `UV_PYTHON_INSTALL_NO_BIN`.
Consequently, this pull request introduces a new `EnvironmentOptions`
abstraction which allows us to express semantics that Clap cannot —
which we probably want anyway because we have an increasing number of
environment variables we're parsing downstream, e.g., #14544 and #14369.
## Summary
When refactoring the addition PR I accidentally introduced a bug where
the debug message would not be output if the default value is used.

## Summary
When installing packages on _very_ slow/overloaded systems it'spossible
to trigger bytecode compilation timeouts, which tends to happen in
environments such as Qemu (especially without KVM/virtio), but also on
systems that are simply overloaded. I've seen this in my Nix builds if I
for example am compiling a Linux kernel at the same time as a few other
concurrent builds.
By making the bytecode compilation timeout adjustable you can work
around such issues. I plan to set `UV_COMPILE_BYTECODE_TIMEOUT=0` in the
[pyproject.nix
builders](https://pyproject-nix.github.io/pyproject.nix/build.html) to
make them more reliable.

## Test Plan
Only manual testing was applied in this instance. There is no existing
automated tests for bytecode compilation timeout afaict.
Closes#14262
## Description
Adds `UV_LIBC` environment variable and implements check within
`Libc::from_env` as recommended here:
https://github.com/astral-sh/uv/issues/14262#issuecomment-3014600313
Gave this a few passes to make sure I follow dev practices within uv as
best I am able. Feel free to call out anything that could be improved.
## Test Plan
Planned to simply run existing test suite. Open to adding more tests
once implementation is validated due to my limited Rust experience.
## Summary
We validate the `uv.toml` when it's discovered automatically, but not
when provided via `--config-file`. The same limitations exist, though --
I think the lack of enforcement is just an oversight.
Closes https://github.com/astral-sh/uv/issues/14650.
Part of #14296
This is the same as `uv tool update-shell` but handles the case where
the Python bin directory is configured to a different path.
```
❯ UV_PYTHON_BIN_DIR=/tmp/foo cargo run -q -- python install --preview 3.13.3
Installed Python 3.13.3 in 1.75s
+ cpython-3.13.3-macos-aarch64-none
warning: `/tmp/foo` is not on your PATH. To use installed Python executables, run `export PATH="/tmp/foo:$PATH"` or `uv python update-shell`.
❯ UV_PYTHON_BIN_DIR=/tmp/foo cargo run -q -- python update-shell
Created configuration file: /Users/zb/.zshenv
Restart your shell to apply changes
❯ cat /Users/zb/.zshenv
# uv
export PATH="/tmp/foo:$PATH"
❯ UV_TOOL_BIN_DIR=/tmp/bar cargo run -q -- tool update-shell
Updated configuration file: /Users/zb/.zshenv
Restart your shell to apply changes
❯ cat /Users/zb/.zshenv
# uv
export PATH="/tmp/foo:$PATH"
# uv
export PATH="/tmp/bar:$PATH"
```
Previously, if installation of executables into the bin directory failed
we'd with a non-zero code. However, if we make this behavior the default
we don't want it to be fatal. There's a `--bin` opt-in to _require_
successful executable installation and a `--no-bin` opt-out to silence
the warning / opt-out of installation entirely.
Part of https://github.com/astral-sh/uv/issues/14296 — we need this
before we can stabilize the behavior.
In #14614 we do the same for writing entries to the Windows registry.
## Summary
You can now override the cache control headers for the Simple API, file
downloads, or both:
```toml
[[tool.uv.index]]
name = "example"
url = "https://example.com/simple"
cache-control = { api = "max-age=600", files = "max-age=365000000, immutable" }
```
