Closes#7118
This only really affects managed interpreters, as we exclude alternative
Python implementations from the search path during the
`VersionRequest::executable_names` part of discovery.
## Summary
Random, but I noticed that we can remove a ton of serialize and
deserialize derives by using `rkyv` for the flat-index caches. (We
already use `rkyv` for these same structs in the registry cache.)
This PR adds some additional sanity checking on resolution graphs to
ensure we can never install different versions of the same package into
the same environment.
I used code similar to this to provoke bugs in the resolver before the
release, but it never made it into `main`. Here, we add the error
checking to the creation of `ResolutionGraph`, since this is where it's
most convenient to access the "full" markers of each distribution.
We only report an error when `debug_assertions` are enabled to avoid
rendering `uv` *completely* unusuable if a bug were to occur in a
production binary. For example, maybe a conflict is detected in a marker
environment that isn't actually used. While not ideal, `uv` is still
usable for any other marker environment.
Closes#5598

First iteration for an implementation. I need to add more tests but

There are two parts to this.
The first is a restructuring and refactoring. We had some debt around
expected executable name generation, which we address here by
consolidating into a single function that generates a combination of
names. This includes a bit of extra code around free-threaded variants
because this was written on top of #7431 — I'll rebase that on top of
this.
The second addresses some bugs around alternative implementations.
Notably, `uv python list` does not discovery executables with
alternative implementation names. Now, we properly generate all of the
executable names for `VersionRequest::Any` (originally implemented in
https://github.com/astral-sh/uv/pull/7508) to properly show all the
implementations we can find:
```
❯ cargo run -q -- python list --no-python-downloads
cpython-3.12.6-macos-aarch64-none /opt/homebrew/opt/python@3.12/bin/python3.12 -> ../Frameworks/Python.framework/Versions/3.12/bin/python3.12
cpython-3.11.10-macos-aarch64-none /opt/homebrew/opt/python@3.11/bin/python3.11 -> ../Frameworks/Python.framework/Versions/3.11/bin/python3.11
cpython-3.9.6-macos-aarch64-none /Library/Developer/CommandLineTools/usr/bin/python3 -> ../../Library/Frameworks/Python3.framework/Versions/3.9/bin/python3
pypy-3.10.14-macos-aarch64-none /opt/homebrew/bin/pypy3 -> ../Cellar/pypy3.10/7.3.17/bin/pypy3
```
While doing both of these changes, I ended up changing the priority of
interpreter discovery slightly. For example, given that the executables
are in the same directory, do we query `python` or `python3.10` first
when you request `--python 3.10`? Previously, we'd check `python3.10`
but I think that was an incorrect optimization. I think we should always
prefer the bare name (i.e. `python`) first. Similarly, this applies to
`python` and an executable for an alternative implementation like
`pypy`. If it's not compatible with the request, we'll skip it anyway.
We might have to query more interpreters with this approach but it seems
rare.

- **Do not attempt to reflink directories on linux**
- **Refactor clone_recursive**
## Summary
On linux, reflink does not work on a directory. Currently, we first
attempt to reflink directory, and only if it fails with `AlreadyExists`
we attempt to reflink recursively.
This has the effect that, on linux, `uv pip install --link-mode=clone`
would always fall back to `copy`.
We resolve this by only attempting to reflink directories on macos. In
the process, we refactored `clone_recursive` in an attempt to make it
easier to reason about its logic.
## Test Plan
I tested that after this change, `uv pip install --link-mode=clone
numpy` would behave as expected in the following cases:
* linux, btrfs filesystem, venv on the same filesystem as cache
(correctly reflinked)
* linux, btrfs filesystem, venv on a different filesystem than cache
(fallback to copy)
I have not tested it on macos or windows, as I currently don't have
access to any macos or windows machines, unfortunately.
## Summary
If the `requires-python` bound expands, the space covered by
`resolution-markers` may no longer include all supported Python
versions. In such cases, we need to avoid reusing the forks (but we
_can_ reuse the preferred versions).
Closes https://github.com/astral-sh/uv/issues/7618.
## Summary
`uv run --project ./path/to/project` now uses the provided directory as
the starting point for any file discovery. However, relative paths are
still resolved relative to the current working directory.
Closes https://github.com/astral-sh/uv/issues/5613.
## Summary
`#[serde(flatten)]` has a disastrous effect on error messages: serde no
longer tells you which field errored, nor does it show it to you in the
diagnostic output.
Before:
```
warning: Failed to parse `pyproject.toml` during settings discovery:
TOML parse error at line 9, column 1
|
9 | [tool.uv]
| ^^^^^^^^^
invalid type: string "foo", expected a sequence
```
After:
```
warning: Failed to parse `pyproject.toml` during settings discovery:
TOML parse error at line 10, column 19
|
10 | extra-index-url = "foo"
| ^^^^^
invalid type: string "foo", expected a sequence
```
Closes https://github.com/astral-sh/uv/issues/7113.
## Summary
This reverts commit 3060fd22c0.
These are now _never_ shown to users, because `tracing` isn't set up at
that point. I'm going to try and improve the solution more holistically,
but this is better than the status quo.
Closes https://github.com/astral-sh/uv/issues/7573.
This enhances the hints generator in the resolver with some heuristic to
detect and warn in case of failures due to version mismatches on a local
package. Those may be the symptom of name conflict/shadowing with a
transitive dependency.
Closes: https://github.com/astral-sh/uv/issues/7329

## Summary
Because a problem was found with Powershell and combining the generated
completion scripts for uv and uvx, let's try separating uv and uvx
command completion scripts.
The generated powershell script template can be seen in clap_complete
source, and it starts with `using` directives, which makes it impossible
(apparently) to concatenate two of those script outputs.
As a side effect, this is available under `uv tool run
--generate-shell-completion` too.
Fixes#7482
## Test Plan
- `eval "$(cargo run --bin uvx -- --generate-shell-completion bash)"`
- Test Powershell
## Summary
The AGPL license is confusing some analyzers. This replaces pretix with
saleor which (similarly) is a web application.
Closes https://github.com/astral-sh/uv/issues/7566.
## Summary
`uv cache prune --ci` will remove the source distribution directory. If
we then need to build a _different_ wheel (e.g., you're building a
package that has Python minor version-specific wheels), we fail, because
we expect the source to be there.
Now, if the source is missing, we re-download it. It would be slightly
easier to just _ignore_ that revision, but that would mean we'd also
lose the already-built wheels -- so if you ran against many Python
versions, we'd continuously lose the cached data.
Closes https://github.com/astral-sh/uv/issues/7543.
## Test Plan
We can add tests, but they _need_ to build non-pure Python wheels, which
tends to be expensive...
For reference:
```console
$ cargo run venv --python 3.12
$ cargo run pip install mercurial==6.8.1 --verbose
$ cargo run cache prune --ci
$ cargo run venv --python 3.11
$ cargo run pip install mercurial==6.8.1 --verbose
```
I also did this with a local `.tar.gz` that I downloaded from PyPI.
## Summary
Both of these can contain rkyv data in their HTTP cache envelopes. As
such, the entries aren't readable by earlier versions of uv, and `uv
cache prune` can break. I should make `uv cache prune` robust to this,
but this feels safest.
## Summary
I think this is just inverted. It means that when we fail in
https://github.com/astral-sh/uv/issues/7553, we show a message for
"invalid Python implementation" (since there are some wheels that don't
match), but we should be showing "invalid platform", matching the order
of operations in our compatibility check.
Closes https://github.com/astral-sh/uv/issues/7553.
Adds display of the target path of the link (since the link filename
itself is basically static) and distinguishes between broken links and
missing files.
## Summary
Improve the description of override-dependencies based on the statement
in `concepts/resolution.md`: "As with constraints, overrides do not add
a dependency on the package and only take effect if the package is
requested in a direct or transitive dependency."
I tested it locally, `concepts/resolution.md` is correct. It would be
better to also include this in the Reference Chapter of the docs.
