The loose consensus is that "fetch" doesn't have much meaning and that a
boolean flag makes more sense from the command line.
1. Adds `--allow-python-downloads` (hidden, default) and
`--no-python-downloads` to the CLI to quickly enable or disable
downloads
2. Deprecates `--python-fetch` in favor of the options from (1)
3. Removes `python-fetch` in favor of a `python-downloads` setting
5. Adds a `never` variant to the enum, allowing even explicit installs
to be disabled via the configuration file
## Test plan
I tested this with various `pyproject.toml`-level settings and `uv venv
--preview --python 3.12.2` and `uv python install 3.12.2` with and
without the new CLI flags.
## Summary
This PR adds a `DistExtension` field to some of our distribution types,
which requires that we validate that the file type is known and
supported when parsing (rather than when attempting to unzip). It
removes a bunch of extension parsing from the code too, in favor of
doing it once upfront.
Closes https://github.com/astral-sh/uv/issues/5858.
## Summary
It's fine for this to be in the cache, I think, since we don't
necessarily need to colocate it with the Python directory.
Closes https://github.com/astral-sh/uv/issues/5747.
Collapses the previous default into "managed" and makes the "managed"
behavior match "installed". People should use "only-managed" if they
want that behavior, it seems overly complicated otherwise.

## Summary
use windows-sys bindings maintained by microsoft devs. winapi didn't has
any updates for more than 3 years
## Test Plan
cargo test. it failed locally because I don't have Python 3.12 installed
## Summary
uv run --directory <path> means that one doesn't have to change to a
project's directory to run programs from it. It makes it possible to use
projects as if they are tool installations.
To support this, first the code reading .python-version was updated so
that
it can read such markers outside the current directory. Note the minor
change this causes (if I'm right), described in the commit.
## Test Plan
One test has been added.
## --directory
Not sure what the name of the argument should be, but it's following uv
sync's directory for now.
Other alternatives could be "--project". Uv run and uv tool run should
probably find common agreement on this (relevant for project-locked
tools).
I've implemented this same change in Rye, some time ago, and then we
went
with --pyproject `<`path to pyproject.toml file`>`. I think using
pyproject.toml file path and not directory was probably a mistake, an
overgeneralization one doesn't need.
## Summary
Adds a `--relocatable` CLI arg to `uv venv`. This flag does two things:
* ensures that the associated activation scripts do not rely on a
hardcoded
absolute path to the virtual environment (to the extent possible; `.csh`
and
`.nu` left as-is)
* persists a `relocatable` flag in `pyvenv.cfg`.
The flag in `pyvenv.cfg` in turn instructs the wheel `Installer` to
create script
entrypoints in a relocatable way (use `exec` trick + `dirname $0` on
POSIX;
use relative path to `python[w].exe` on Windows).
Fixes: #3863
## Test Plan
* Relocatable console scripts covered as additional scenarios in
existing test cases.
* Integration testing of boilerplate generation in `venv`.
* Manual testing of `uv venv` with and without `--relocatable`
## Summary
If you have an executable path on a network share path (like
`\\some-host\some-share\...\python.exe`), canonicalizing it adds the
`\\?` prefix, but dunce cannot safely strip it.
This PR changes the Windows logic to avoid canonicalizing altogether. We
don't really expect symlinks on Windows, so it seems unimportant to
resolve them.

## Summary
Currently, `uv` refuses to install anything on GraalPy. This is
currently blocking GraalPy testing with cibuildwheel, since manylinux
includes both `uv` and `graalpy` (but doesn't test with `uv`), whereas
cibuildwheel defaults to `uv`. See e.g.
2750618295
where it gives
```
+ python -m build /project/sample_proj --wheel --outdir=/tmp/cibuildwheel/built_wheel --installer=uv
* Creating isolated environment: venv+uv...
* Using external uv from /usr/local/bin/uv
* Installing packages in isolated environment:
- setuptools >= 40.8.0
> /usr/local/bin/uv pip install "setuptools >= 40.8.0"
< error: Unknown implementation: `graalpy`
```
## Test Plan
I simply based the GraalPy support on PyPy and added some small tests.
I'm open to discussing how to test this. GraalPy is available for
manylinux images and with setup-python, so we should be able to add
tests against it to the CI. I locally confirmed by installing `uv` into
a GraalPy venv and then trying things like `uv pip install Pillow` and
testing those extensions.
Search for all `python3.x` minor versions in PATH, skipping those we
already know we can use.
For example, let's say `python` and `python3` are Python 3.10. When a
user requests `>= 3.11`, we still need to find a `python3.12` in PATH.
We do so with a regex matcher.
Fixes#4709
## Summary
Resolves#5139
`PythonInstallationKey` was sorted as a string, which caused `3.8` to
appear before `3.11`. This update changes the sorting of
`PythonInstallationKey` to be a descending order by version.

```
## Summary
Like https://github.com/astral-sh/uv/pull/4808 but with a few more
changes. I suspect this will require some bikeshedding but I find the
use of "installation" and "installed" in the same sentence to be kind of
a lot.
