## 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.
## Summary
There are a few ideas at play here:
1. pip always strips versions to the release when evaluating against a
`Requires-Python`, so we now do the same. That means, e.g., using
`3.13.0b0` will be accepted by a project with `Requires-Python: >=
3.13`, which does _not_ adhere to PEP 440 semantics but is somewhat
intuitive.
2. Because we know we'll only be evaluating against release-only
versions, we can use different semantics in PubGrub that let us collapse
ranges. For example, `python_version >= '3.10' or python_version <
'3.10'` can be collapsed to the truthy marker.
Closes https://github.com/astral-sh/uv/issues/4714.
Closes https://github.com/astral-sh/uv/issues/4272.
Closes https://github.com/astral-sh/uv/issues/4719.
Remove wheels from the lockfile that don't match the required python
version. For example, we remove
`charset_normalizer-3.3.2-cp311-cp311-win_amd64.whl` when we have
`requires-python = ">=3.12"`.
Our snapshots barely show changes since we avoid the large binaries for
which matters. Here are 3 real world `uv.lock` before/after comparisons
to show the large difference:
*
[warehouse](https://gist.github.com/konstin/9a1ed6a32b410e250fcf4c6ea8c536a5)
(5677 -> 4214)
*
[transformers](https://gist.github.com/konstin/5636281b5226f64aa44ce3244d5230cd)
(6484 -> 5816)
*
[github-wikidata-bot](https://gist.github.com/konstin/ebbd7b9474523aaa61d9a8945bc02071)
(793 -> 454)
We only remove wheels we are certain don't match the python version and
still keep those with unknown tags. We could remove even more wheels by
also considering other markers, e.g. removing linux wheels for a
windows-only dep, but we would trade complex, easy-to-get-wrong logic
for diminishing returns.
## Summary
Check the sha256 checksum when downloading a managed python toolchain.

## Summary
This seems like another good candidate for environment caching. If you
run a script repeatedly, we can just use the existing cached
environment.

## Summary
The resolver sometimes starts HTTP requests that end up not being
necessary. When dropping the Tokio runtime before exiting we currently
wait for those to complete. This can cause noticeable hangs in the CLI,
particularly when the runtime is blocked on slow DNS resolution.
Resolves https://github.com/astral-sh/uv/issues/4599.
## Test Plan
This change resolves any reproducible hangs for me locally.
## Summary
The basic strategy:
- When the user does `uv tool run`, we resolve the `from` and `with`
requirements (always).
- After resolving, we generate a hash of the requirements. For now, I'm
just converting to a lockfile and hashing _that_, but that's an
implementation detail.
- Once we have a hash, we _also_ hash the interpreter.
- We then store environments in
`${CACHE_DIR}/${INTERPRETER_HASH}/${RESOLUTION_HASH}`.
Some consequences:
- We cache based on the interpreter, so if you request a different
Python, we'll create a new environment (even if they're compatible).
This has the nice side-effect of ensuring that we don't use environments
for interpreters that were later deleted.
- We cache the `from` and `with` together. In practice, we may want to
cache them separately, then layer them? But this is also an
implementation detail that we could change later.
- Because we use the lockfile as the cache key, we will invalidate the
cache when the format changes. That seems ok, but we could improve it in
the future by generating a stable hash from a lockfile that's
independent of the schema.
Closes https://github.com/astral-sh/uv/issues/4752.

Closes#4653
## Summary
Adds the tool version to the list command right beside the tool name
```
$ uv tool list
black v24.2.0
```
Following the proposed format discussed in #4653
## Test Plan
`cargo test tool_list`

The changes in https://github.com/astral-sh/uv/pull/4708 caused an
overflow in debug mode only of the 1MB default stack size in windows
during clap. This means that even trivial wrong argument tests would
fail without increasing the stack size. As remedy, we box the clap
types.
This fell out of my investigation of
https://github.com/astral-sh/uv/issues/4774 but the bug was fixed by the
reporter in #4775
- Adds support for `GH_TOKEN` authentication again — basically needed to
avoid rate limits when hacking on this.
- Clarifies some handling and logging of flavors
## Summary
This doesn't cache the tool environment; rather, it just uses the `tool
install` environment if it satisfies the request.
Closes https://github.com/astral-sh/uv/issues/4742.
Previously this displayed:
```
❯ cargo run -q -- --help
The command line interface for the uv binary.
Usage: uv [OPTIONS] <COMMAND>
```
This is.. weird. Here I remove it entirely. I could see adding
`about_long` text being helpful in the future.
Fix#4774.
## Summary
Change the python interpreter for linux installed with `uv python` to an
optimized one.
## Test Plan
I ran the following command on Linux (glibc) to confirm that an
optimized (not debug built) Python is installed.
```bash
# install python
uv python install 3.12.3
# check build type
uv run python -c "import sysconfig;print(sysconfig.get_config_var('Py_DEBUG'))"
0
```
## Summary
This used to be necessary because we purged the cache in the
`InstallPlan` if the user passed `--reinstall`. _However_, we later
changed the cache to be append-only.
## Test Plan
I ran through the test plan in https://github.com/astral-sh/uv/pull/933,
which includes an integration test and running `uv pip install
--reinstall` with:
```text
setuptools
devpi @ e334eb4dc9/devpi-2.2.0.tar.gz
```
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)

Closes#4654
## Summary
The purpose of this is to show the entrypoints of each tool when running
`uv tool list` as below:
```
$ uv tool list
black
black
blackd
```
I used the proposed formatting as it was written in #4653 by @blueraft.
I had to use spaces instead of tabs in order to make the test
successful. Indeed in the test we are using a raw string and I did not
manage to make the test pass when escaping the tab in the list.rs file
so I used spaces everywhere.
I had a deeper look into #4653 as well but it is more difficult as we
need to get the version of the tool in the Tool object, I will continue
on this next one later.
Please tell me if anything else is needed I tried to follow the
contribution guidelines but I might have forgotten something.
Have a great day!

## Summary
For now the semantics are such that if the requested requirements from
the command line don't match the receipt (or if any `--reinstall` or
`--upgrade` is requested), we proceed with an install, passing the
`--reinstall` and `--upgrade` to the underlying Python environment.
This may lead to some unintuitive behaviors, but it's simplest for now.
For example:
- `uv tool install black<24` followed by `uv tool install black
--upgrade` will install the latest version of `black`, removing the
`<24` constraint.
- `uv tool install black --with black-plugin` followed by `uv tool
install black` will remove `black-plugin`.
Closes https://github.com/astral-sh/uv/issues/4659.
In #3514 and #2755, users had intermittent network errors, but it was
not always clear whether we had already retried these requests or not.
Building upon https://github.com/TrueLayer/reqwest-middleware/pull/159,
this PR adds the number of retries to the error message, so we can see
at first glance where we're missing retries and where we might need to
change retry settings.
Example error trace:
```
Could not connect, are you offline?
Caused by: Request failed after 3 retries
Caused by: error sending request for url (https://pypi.org/simple/uv/)
Caused by: client error (Connect)
Caused by: dns error: failed to lookup address information: Name or service not known
Caused by: failed to lookup address information: Name or service not known
```
This code is ugly since i'm missing a better pattern for attaching
context to reqwest middleware errors in
https://github.com/TrueLayer/reqwest-middleware/pull/159.
## Summary
Given:
```text
numpy >=1.26 ; python_version >= '3.9'
numpy <1.26 ; python_version < '3.9'
```
When resolving for Python 3.8, we need to narrow the `requires-python`
requirement in the top branch of the fork, because `numpy >=1.26` all
require Python 3.9 or later -- but we know (in that branch) that we only
need to _solve_ for Python 3.9 or later.
Closes https://github.com/astral-sh/uv/issues/4669.
## Summary
This is required to solve https://github.com/astral-sh/uv/issues/4669,
because the `Requires-Python` version can now vary across a resolution.
For example, within certain forks, we might have a more narrow range,
which would allow us to use distributions that would not be allowed for
the global resolution.
This should be fine because `requires-python` is part of the package
metadata, so it should be consistent between files within a package
version. As such, there shouldn't be any risk that we incorrectly
prioritize distributions by omitting this information.
(To be more specific, the risk is something like: we prioritize some
wheel over a source distribution within a package-version, so we don't
track the source distribution at all. Then, later, when we choose a
candidate, we see that the wheel doesn't meet the `Requires-Python`
requirement, even though the source distribution _would've_ met it. If
files within a distribution could have varied support, this would be a
real risk.)
I think `--toolchain-preference system` is sufficiently clear and
`--toolchain-preference prefer-system` is excessively verbose. This was
discussed in the original pull request at
https://github.com/astral-sh/uv/pull/4424 but because we had a case for
preferring "installed managed" toolchains I was hesitant to change it.
Now that I've dropped that in #4601, I think we can drop the prefix.
