## Summary
This follows Ruff's design exactly: you can provide a version specifier
(like `>=0.5`), and we'll enforce it at runtime.
Closes https://github.com/astral-sh/uv/issues/8605.
uv gives priorities to packages by package name, not by virtual package
(`PubGrubPackage`). pubgrub otoh when prioritizing order the virtual
packages. When the order of virtual packages changes, uv changes its
resolutions and error messages. This means uv was depending on
implementation details of pubgrub's prioritization caching.
This broke with https://github.com/pubgrub-rs/pubgrub/pull/299, which
added a tiebreaker term that made pubgrub's sorting deterministic given
a deterministic ordering of allocating the packages (which happens the
first time pubgrub sees a package).
The new custom tiebreaker decreases the difference to upstream pubgrub.
Build failures are one of the most common user facing failures that
aren't "obivous" errors (such as typos) or resolver errors. Currently,
they show more technical details than being focussed on this being an
error in a subprocess that is either on the side of the package or -
more likely - in the build environment, e.g. the user needs to install a
dev package or their python version is incompatible.
The new error message clearly delineates the part that's important (this
is a build backend problem) from the internals (we called this hook) and
is consistent about which part of the dist building stage failed. We
have to calibrate the exact wording of the error message some more. Most
of the implementation is working around the orphan rule, (this)error
rules and trait rules, so it came out more of a refactoring than
intended.
Example:

Enable `lzma-sys/static` through the performance feature not only in uv,
but in uv-dev and uv-bench too, to avoid the system dependency on
`liblzma-dev`.

Companion PR: https://github.com/astral-sh/pubgrub/pull/36
Requires for test coverage: https://github.com/astral-sh/packse/pull/230
When two packages A and B conflict, we have the option to choose a lower
version of A, or a lower version of B. Currently, we determine this by
the order we saw a package (assuming equal specificity of the
requirement): If we saw A before B, we pin A until all versions of B are
exhausted. This can lead to undesirable outcomes, from cases where it's
just slow (sentry) to others cases without lower bounds where be
backtrack to a very old version of B. This old version may fail to build
(terminating the resolution), or it's a version so old that it doesn't
depend on A (or the shared conflicting package) anymore - but also is
too old for the user's application (fastapi). #8157 collects such cases,
and the `wrong-backtracking` packse scenario contains a minimized
example.
We try to solve this by tracking which packages are "A"s, culprits, and
"B"s, affected, and manually interfering with project selection and
backtracking. Whenever a version we just chose is rejected, we give the
current package a counter for being affected, and the package it
conflicted with a counter for being a culprit. If a package accumulates
more counts than a threshold, we reprioritize: Undecided after the
culprits, after the affected, after packages that only have a single
version (URLs, `==<version>`). We then ask pubgrub to backtrack just
before the culprit. Due to the changed priorities, we now select package
B, the affected, instead of package A, the culprit.
To do this efficiently, we ask pubgrub for the incompatibility that
caused backtracking, or just the last version to be discarded (due to
its dependencies). For backtracking, we use the last incompatibility
from unit propagation as a heuristic. When a version is discarded
because one of its dependencies conflicts with the partial solution, the
incompatibility tells us the package in the partial solution that
conflicted.
We only backtrack once per package, on the first time it passes the
threshold. This prevents backtracking loops in which we make the same
decisions over and over again. But we also changed the priority, so that
we shouldn't take the same path even after the one time we backtrack (it
would defeat the purpose of this change).
There are some parameters that can be tweaked: Currently, the threshold
is set to 5, which feels not too eager with so me of the conflicts that
we want to tolerate but also changes strategies quickly. The relative
order of the new priorities can also be changed, as for each (A, B) pair
the priority of B is afterwards lower than that for A. Currently,
culprits capture conflict for the whole package, but we could limit that
to a specific version. We could discard conflict counters after
backtracking instead of keeping them eternally as we do now. Note that
we're always taking about pairs (A, B), but in practice we track
individual packages, not pairs.
A case that we wouldn't capture is when B is only introduced to the
dependency graph after A, but I think that would require cyclical
dependency for A and B to conflict? There may also be cases where
looking at the last incompatibility is insufficient.
Another example that we can't repair with prioritization is
urllib3/boto3/botocore: We actually have to check all the newer versions
of boto3 and botocore to identify the version that allows with the older
urllib3, no shortcuts allowed.
```
urllib3<1.25.4
boto3
```
All examples I tested were cases with two packages where we only had to
switch the order, so I've abstracted them into a single packse case.
This PR changes the resolution for certain paths, and there is the risk
for regressions.

## Summary
This PR reimplements
[`sysconfigpatcher`](https://github.com/bluss/sysconfigpatcher) in Rust
and applies it to our Python installations at install-time, ensuring
that the `sysconfig` data is more likely to be correct.
For now, we only rewrite prefixes (i.e., any path that starts with
`/install` gets rewritten to the correct absolute path for the current
machine).
Unlike `sysconfigpatcher`, this PR does not yet do any of the following:
- Patch `pkginfo` files.
- Change `clang` references to `cc`.
A few things that we should do as follow-ups, in my opinion:
1. Rewrite
[`AR`](c1ebf8ab92/src/sysconfigpatcher.py (L61)).
2. Remove `-isysroot`, which we already do for newer builds.
This is like #9556, but at the level of all other builds, including the
resolver and installer. Going through PEP 517 to build a package is
slow, so when building a package with the uv build backend, we can call
into the uv build backend directly instead: No temporary virtual env, no
temp venv sync, no python subprocess calls, no uv subprocess calls.
This fast path is gated through preview. Since the uv wheel is not
available at test time, I've manually confirmed the feature by comparing
`uv venv && cargo run pip install . -v --preview --reinstall .` and `uv
venv && cargo run pip install . -v --reinstall .`. When hacking the
preview so that the python uv build backend works without the setting
the direct build also (wheel built with `maturin build --profile
profiling`), we can see the perfomance difference:
```
$ hyperfine --prepare "uv venv" --warmup 3 \
"UV_PREVIEW=1 target/profiling/uv pip install --no-deps --reinstall scripts/packages/built-by-uv --preview" \
"target/profiling/uv pip install --no-deps --reinstall scripts/packages/built-by-uv --find-links target/wheels/"

3.48 ± 0.29 times faster than target/profiling/uv pip install --no-deps --reinstall scripts/packages/built-by-uv --find-links target/wheels/
```
Do we need a global option to disable the fast path? There is one for
`uv build` because `--force-pep517` moves `uv build` much closer to a
`pip install` from source that a user of a library would experience (See
discussion at #9610), but uv overall doesn't really make guarantees
around the build env of dependencies, so I consider the direct build a
valid option.
Best reviewed commit-by-commit, only the last commit is the actual
implementation, while the preview mode introduction is just a
refactoring touching too many files.
When looking at the build frontend code, I noticed that we always pass
every single field of the shared state to the build dispatch:
```rust
let build_dispatch = BuildDispatch::new(
...
&state.index,
&state.git,
&state.capabilities,
&state.in_flight,
...
);
```
We can abstract this by moving `SharedState` into the build dispatch.
The `BuildDispatch` then has only immutable fields and the
`SharedState`. Since the `SharedState` is all `Arc`s, we can clone it
freely.
When performing a noop sync, we don't need the rayon threadpool, yet we
pay for its initialization:

Be making the initialization lazy, we avoid that cost:

This code runs every time before user code in `uv run`.
This means that before calling rayon, one now needs to call
`LazyLock::force(&RAYON_INITIALIZE);`.

## Summary
In uv-globfilter, use the workspace `fs-err` in `dev-dependencies`.
This fixes an unnecessary dev-dependency on `fs-err` 2.x even after the
workspace fs-err was updated to 3.x in
https://github.com/astral-sh/uv/pull/8625.
The `Cargo.lock` file still has `fs-err v2.11.0` after this PR, but it
is via `tracing-durations-export v0.3.0` rather than directly required
by any `uv` crate.
## Test Plan
<!-- How was it tested? -->
```
$ cd crates/uv-globfilter/

## Summary
Update the URL to the "tl" crate since the repository has been
transferred to astral-sh/. This is of no real consequence, except it
keeps triggering Gentoo linter that detects permanently redirected URL.
## Test Plan

## Summary
This PR should not contain any user-visible changes, but the goal is to
refactor the `Resolution` type to retain a dependency graph. We want to
be able to explain _why_ a given package was excluded on error (see:
https://github.com/astral-sh/uv/issues/8962), which in turn requires
that at install time, we can go back and figure out the dependency
chain. At present, `Resolution` is just a map from package name to
distribution; this PR remodels it as a graph in which each node is a
package, and the edges contain markers plus extras or dependency groups.
A first milestone: source tree -> source dist -> wheel -> install works.
This PR adds a test for this.
There's obviously a lot still missing, including basics such as the
Readme inclusion.
When doing a directory traversal for source dist inclusion, we want to
offer the user include and exclude options, and we want to avoid
traversing irrelevant directories. The latter is important for
performance, especially on network file systems, but also with large
data directories, or (not-included) directories with other permissions.
To support this, we introduce `GlobDirFilter`, which uses a DFA from
regex_automata to determine whether any children of a directory can be
included and skips the directory if not.
The globs are based on PEP 639. The syntax is more restricted than glob
or globset, but it's standardized. I chose it over glob or globset
because we're already using this syntax for `project.license-files` a
required by PEP 639, so it makes sense to use the same globs for all
includes (see e.g.
4f52a3bb62/pyproject.toml (L36-L48)
for example with same semantics for include and exclude)
### Semantics
Glob semantics are complex due to mixing directories and files,
expectations around simplicity and our need to exclude most of the tree
in the project from traversal. The current draft uses a syntax that
optimizes for simple default use cases for the start.
#### includes
Glob expressions which files and directories to include in the source
distribution.
Includes are anchored, which means that `pyproject.toml` includes only
`<project root>/pyproject.toml`. Use for example `assets/**/sample.csv`
to include for all
`sample.csv` files in `<project root>/assets` or any child directory. To
recursively include
all files under a directory, use a `/**` suffix, e.g. `src/**`. For
performance and
reproducibility, avoid unanchored matches such as `**/sample.csv`.
The glob syntax is the reduced portable glob from
[PEP 639](https://peps.python.org/pep-0639/#add-license-FILES-key).
#### excludes
Glob expressions which files and directories to exclude from the
previous source
distribution includes.
Excludes are not, which means that `__pycache__` excludes all
directories named
`__pycache__` and it's children anywhere. To anchor a directory, use a
`/` prefix, e.g.,
`/dist` will exclude only `<project root>/dist`.
The glob syntax is the reduced portable glob from
[PEP 639](https://peps.python.org/pep-0639/#add-license-FILES-key).
This adds support for providing conflicting group names in addition to
extra names to `Conflicts`.
This merely makes "room" for it in the types while keeping everything
working. We'll add proper support for it in the next commit.
Note that one interesting trick we do here is depend directly on
`hashbrown` so that we can make use of its `Equivalent` trait. This in
turn lets us use things like `ConflictItemRef` as a lookup key for a
hashset that contains `ConflictItem`. This mirrors using a `&str` as a
lookup key for a hashset that contains `String`, but works for arbitrary
types. `std` doesn't support this, but `hashbrown` does. This trick in
turn lets us simplify some of our data structures.
This also rejiggers some of the serde-interaction with the conflicting
types. We now use a wire type to represent our conflicting items for
more flexibility. i.e., Support `extra` XOR `group` fields.
This PR adds support for conflicting extras. For example, consider
some optional dependencies like this:
```toml
[project.optional-dependencies]
project1 = ["numpy==1.26.3"]
project2 = ["numpy==1.26.4"]
```
These dependency specifications are not compatible with one another.
And if you ask uv to lock these, you'll get an unresolvable error.
With this PR, you can now add this to your `pyproject.toml` to get
around this:
```toml
[tool.uv]
conflicting-groups = [
[
{ package = "project", extra = "project1" },
{ package = "project", extra = "project2" },
],
]
```
This will make the universal resolver create additional forks
internally that keep the dependencies from the `project1` and
`project2` extras separate. And we make all of this work by reporting
an error at **install** time if one tries to install with two or more
extras that have been declared as conflicting. (If we didn't do this,
it would be possible to try and install two different versions of the
same package into the same environment.)
This PR does *not* add support for conflicting **groups**, but it is
intended to add support in a follow-up PR.
Closes#6981Fixes#8024
Ref #6729, Ref #6830
This should also hopefully unblock
https://github.com/dagster-io/dagster/pull/23814, but in my testing, I
did run into other problems (specifically, with `pywin`). But it does
resolve the problem with incompatible dependencies in two different
extras once you declare `test-airflow-1` and `test-airflow-2` as
conflicting for `dagster-airflow`.
NOTE: This PR doesn't make `conflicting-groups` public yet. And in a
follow-up PR, I plan to switch the name to `conflicts` instead of
`conflicting-groups`, since it will be able to accept conflicting extras
_and_ conflicting groups.

## Summary
This PR builds off of https://github.com/astral-sh/uv/pull/6738 to fix
#6724 (sorry for the new PR @charliermarsh I didn't want to push to your
branch, not even sure if I could). The reason the original PR doesn't
fix the issue described in #6724 is because the fastapi is ran in the
project context (as I assume a lot of use cases are). This PR adds an
extra commit to handle the signals in the project/run.rs file
~It also addresses the comment
[here](https://github.com/astral-sh/uv/pull/6738/files#r1734757548) to
not use the tokio ctrl-c method since we are now handling SIGINT
ourselves~ update, tokio handles SIGINT in a platform agnostic way,
intercepting this ouselves makes the logic more complicated with
windows, decided to leave the tokio ctrl-c handler
~[This
comment](https://github.com/astral-sh/uv/pull/6738/files#r1743510140)
remains unaddressed, however, the Child process does not have any other
methods besides kill() so I don't see how we can "preserve" the
interrupt call :/ I tried looking around but no luck.~ updated, this PR
is reduced to only handling SIGTERM propagation on unix machines, and
the sigterm call to the child is preserved by making use of the nix
package, instead of relying on tokio which only allowed for `kill()` on
a child process
## Test Plan
I tested this by building the docker container locally with these
changes and tagging it "myuv", and then using that as the base image in
uv-docker-example, (and ofc following the rest of the repro issues in
#6724. In my tests I see that ctrl-c in the docker-compose up command
exits the process almost immediately 👍

Very basic source distribution support. What's included:
- Include and exclude patterns (hard-coded): Currently, we have
globset+walkdir in one part and glob in the other. I'll migrate
everything to globset+walkset and some custom perf optimizations to
avoid traversing irrelevant directories on top. I'll also pick a glob
syntax (or subset), PEP 639 seems like a good candidate since it's
consistent with what we already have to support.
- Add the `PKG-INFO` file with metadata: Thanks to Code Metadata 2.2,
this metadata is reliable and can be read statically by external tools.
Example output:
```
$ tar -ztvf dist/dummy-0.1.0.tar.gz

No tests since the source distributions don't build valid wheels yet.
Previously, we'd use the `--reinstall` flag to determine if we should
replace existing Python executables in the bin directory during an
install. There are a few problems with this:
- We replace executables we don't manage
- We can replace executables from other uv Python installations during
reinstall (surprising)
- We don't do the "right" thing when installing patch versions e.g.
installing `3.12.4` then `3.12.6` would fail without the reinstall flag
In `uv tool`, we have separate `--force` and `--reinstall` concepts.
Here we separate the flags (`--force` was previously just a
`--reinstall` alias) and add inspection of the existing executables to
inform a decision on replacement.
In brief, we will:
- Replace any executables with `--force`
- Replace executables for the same installation with `--reinstall`
- Replace executables for an older patch version by default
## Summary
This PR pulls in https://github.com/astral-sh/uv/pull/8263 and
https://github.com/astral-sh/uv/pull/8463, which were originally merged
into the v0.5 tracking branch but can now be committed separately, as
we've made `.env` loading opt-in.
In summary:
- `.env` loading is now opt-in (`--env-file .env`).
- `.env` remains supported on `uv run`, so it's meant for providing
environment variables to the run command, rather than to uv itself.

## Summary
Resolves#8417
I've just begun learning procedural macros, so this PR is more of a
proof of concept. It's still a work in progress, and I welcome any
assistance or feedback.
## Summary
This PR improves the interaction of `--frozen` such that we reduce the
dependency on the `pyproject.toml` and increase the dependency on the
`uv.lock`. Specifically, we now read the list of workspace members from
the `uv.lock` rather than the `pyproject.toml`, which means we don't
need to discover the member `pyproject.toml` files in order to perform a
`uv sync --frozen --all-packages`.
This still utilizes the RFC 2822 datetime formatter, but utilizes new
methods [added in jiff 0.1.14] to emit timestamps in a format strictly
compatible with RFC 9110.
It seems like most HTTP servers were pretty flexible and supported RFC
2822 datetime formats, but #8747 shows at least one case where that
isn't true. Given that the [MDN docs prescribe RFC 9110], we defer to
them.
Fixes#8747

Incorporating #8637 into #8458
- Adds `python-managed` feature selection to Windows CI for `python
install` tests
- Adds trampoline sniffing utilities to `uv-trampoline-builder`
- Uses a trampoline to install Python executables into the `PATH` on
Windows
Updates `uv python install` to link `python3.x` in the executable
directory (i.e., `~/.local/bin`) to the the managed interpreter path.
Includes
- #8569
- #8571
Remaining work
- #8663
- #8650
- Add an opt-out setting and flag
- Update documentation
Currently, our trampoline is used to convert `<command> [args]` to
`python <command> [args]` for script entrypoints installed into virtual
environments. For #8458, it'd be nice to convert a shim `python3.12
[args]` to `python [args]`. Here, we modify the trampolines to support
this use-case.
The only change we really need here is to avoid injecting `<command>`
into the child process. We change the "magic number" at the end of the
trampoline executables from `UVUV` to `UVSC` and `UVPY` which define
"script" and "python" variants to the trampoline. We then omit the
`<command>` injection in the latter case. We also omit writing the zip
script payload.
To support construction of the new variant, a new
`uv-trampoline-builder` crate is introduced — this avoids requirements
on `uv-install-wheel` in future work. I also use `uv-trampoline-builder`
to consolidate some of the test setup for `uv-trampoline`.
There should be no backwards compatibility concerns, since trampolines
are fully self-referential.
I rebased to fix the commits at the end, as this took many iterations to
get working via CI. This should roughly be reviewable by commit if you
prefer.
## Summary
Instead of creating a new entry, we should reuse the existing entry (to
preserve decor); similarly, we should avoid overwriting fields that are
already "correct".
Closes https://github.com/astral-sh/uv/issues/8483.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Before this PR (and since 651fe6f4e6) `uv`
depends on a git snapshot of `rust-netrc` at
544f3890b6,
with fixes from https://github.com/gribouille/netrc/pull/3 for
https://github.com/astral-sh/uv/issues/8003.
Since `rust-netrc` 0.1.2 was just released, and it includes those fixes
– plus an additional [change to support
`~`-expansion](ca0860c0a0)
– `uv` can go back to depending on published crates from crates.io.

## Summary
This PR enables users to provide index credentials via named environment
variables.
For example, given an index named `internal` that requires a username
(`public`) and password
(`koala`), you can define the index (without credentials) in your
`pyproject.toml`:
```toml
[[tool.uv.index]]
name = "internal"
url = "https://pypi-proxy.corp.dev/simple"
```
Then set the `UV_INDEX_INTERNAL_USERNAME` and
`UV_INDEX_INTERNAL_PASSWORD`
environment variables, where `INTERNAL` is the uppercase version of the
index name:
```sh
export UV_INDEX_INTERNAL_USERNAME=public
export UV_INDEX_INTERNAL_PASSWORD=koala
```
## Summary
This PR adds a first-class API for defining registry indexes, beyond our
existing `--index-url` and `--extra-index-url` setup.
Specifically, you now define indexes like so in a `uv.toml` or
`pyproject.toml` file:
```toml
[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cu121"
```
You can also provide indexes via `--index` and `UV_INDEX`, and override
the default index with `--default-index` and `UV_DEFAULT_INDEX`.
### Index priority
Indexes are prioritized in the order in which they're defined, such that
the first-defined index has highest priority.
Indexes are also inherited from parent configuration (e.g., the
user-level `uv.toml`), but are placed after any indexes in the current
project, matching our semantics for other array-based configuration
values.
You can mix `--index` and `--default-index` with the legacy
`--index-url` and `--extra-index-url` settings; the latter two are
merely treated as unnamed `[[tool.uv.index]]` entries.
### Index pinning
If an index includes a name (which is optional), it can then be
referenced via `tool.uv.sources`:
```toml
[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cu121"
[tool.uv.sources]
torch = { index = "pytorch" }
```
If an index is marked as `explicit = true`, it can _only_ be used via
such references, and will never be searched implicitly:
```toml
[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cu121"
explicit = true
[tool.uv.sources]
torch = { index = "pytorch" }
```
Indexes defined outside of the current project (e.g., in the user-level
`uv.toml`) can _not_ be explicitly selected.
(As of now, we only support using a single index for a given
`tool.uv.sources` definition.)
### Default index
By default, we include PyPI as the default index. This remains true even
if the user defines a `[[tool.uv.index]]` -- PyPI is still used as a
fallback. You can mark an index as `default = true` to (1) disable the
use of PyPI, and (2) bump it to the bottom of the prioritized list, such
that it's used only if a package does not exist on a prior index:
```toml
[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cu121"
default = true
```
### Name reuse
If a name is reused, the higher-priority index with that name is used,
while the lower-priority indexes are ignored entirely.
For example, given:
```toml
[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cu121"
[[tool.uv.index]]
name = "pytorch"
url = "https://test.pypi.org/simple"
```
The `https://test.pypi.org/simple` index would be ignored entirely,
since it's lower-priority than `https://download.pytorch.org/whl/cu121`
but shares the same name.
Closes#171.
## Future work
- Users should be able to provide authentication for named indexes via
environment variables.
- `uv add` should automatically write `--index` entries to the
`pyproject.toml` file.
- Users should be able to provide multiple indexes for a given package,
stratified by platform:
```toml
[tool.uv.sources]
torch = [
{ index = "cpu", markers = "sys_platform == 'darwin'" },
{ index = "gpu", markers = "sys_platform != 'darwin'" },
]
```
- Users should be able to specify a proxy URL for a given index, to
avoid writing user-specific URLs to a lockfile:
```toml
[[tool.uv.index]]
name = "test"
url = "https://private.org/simple"
proxy = "http://<omitted>/pypi/simple"
```
## Summary
Cache the path to git executable in a `LazyLock` and reuse it throughout
the process. This might reduce some costs on finding the git executable.
## Summary
This PR declares and documents all environment variables that are used
in one way or another in `uv`, either internally, or externally, or
transitively under a common struct.
I think over time as uv has grown there's been many environment
variables introduced. Its harder to know which ones exists, which ones
are missing, what they're used for, or where are they used across the
code. The docs only documents a handful of them, for others you'd have
to dive into the code and inspect across crates to know which crates
they're used on or where they're relevant.
This PR is a starting attempt to unify them, make it easier to discover
which ones we have, and maybe unlock future posibilities in automating
generating documentation for them.
I think we can split out into multiple structs later to better organize,
but given the high influx of PR's and possibly new environment variables
introduced/re-used, it would be hard to try to organize them all now
into their proper namespaced struct while this is all happening given
merge conflicts and/or keeping up to date.
I don't think this has any impact on performance as they all should
still be inlined, although it may affect local build times on changes to
the environment vars as more crates would likely need a rebuild. Lastly,
some of them are declared but not used in the code, for example those in
`build.rs`. I left them declared because I still think it's useful to at
least have a reference.
Did I miss any? Are their initial docs cohesive?
Note, `uv-static` is a terrible name for a new crate, thoughts? Others
considered `uv-vars`, `uv-consts`.

## Summary
This PR adds the ability to list available scripts in the environment
when `uv run` is invoked without any arguments.
It somewhat mimics the behavior of `rye run` command
(See https://rye.astral.sh/guide/commands/run).
This is an attempt to fix#4024.
## Test Plan
I added test cases. The CI pipeline should pass.
### Manuel Tests
```shell
❯ uv run
Provide a command or script to invoke with `uv run <command>` or `uv run script.py`.
The following scripts are available:
normalizer
python
python3
python3.12
See `uv run --help` for more information.
```

## Summary
We now display the "Did you mean `python-dotenv`?"-style errors on build
failure, rather than in `uv add`. This is less opinionated and couples
us less to specific content in the registry.
## Test Plan

## Summary
This PR enables users to provide multiple source entries in
`tool.uv.sources`, e.g.:
```toml
[tool.uv.sources]
httpx = [
{ git = "https://github.com/encode/httpx", tag = "0.27.2", marker = "sys_platform == 'darwin'" },
{ git = "https://github.com/encode/httpx", tag = "0.24.1", marker = "sys_platform == 'linux'" },
]
```
The implementation is relatively straightforward: when we lower the
requirement, we now return an iterator rather than a single requirement.
In other words, the above is transformed into two requirements:
```txt
httpx @ git+https://github.com/encode/httpx@0.27.2 ; sys_platform == 'darwin'
httpx @ git+https://github.com/encode/httpx@0.24.1 ; sys_platform == 'linux'
```
We verify (at deserialization time) that the markers are
non-overlapping.
Closes https://github.com/astral-sh/uv/issues/3397.
## Summary
This was brought up on Twitter recently. `dotenv` hasn't been updated in
years and doesn't build successfully anymore. Users almost always mean
to install `python-dotenv`. I think we can add helpful hints here to
point users in the right direction.
## Test Plan

## Summary
This is a longstanding piece of technical debt. After we resolve, we
have a bunch of `ResolvedDist` entries. We then convert those to
`Requirement` (which is lossy -- we lose information like "the index
that the package was resolved to"), and then back to `Dist`.
## Summary
Similiar to `cargo init --vcs <VCS>`, this PR adds the `--vcs <VCS>`
flag for `uv init`, allowing to create a version control system during
initialization. By default, `uv init` will create a Git repository if
the `--vcs` flag is not provided. Use `--vcs none` to disable this
feature.
Currently, only Git is supported. While Cargo also supports hg, pijul,
and fossil, this initial PR only includes Git. We can add more later if
there are any user requests.

uv will soon support both a build frontend (`uv build`) and a build
backend (`build-system = "uv"`). To avoid the name clash, I'm renaming
the `uv-build` crate to `uv-build-frontend`. In a follow-up PR, I will
add a `uv-build-backend` crate with the build backend implementation.
This PR adds support for upgrading the build environment of tools with
the addition of a ```--python``` argument to ```uv upgrade```, as
specified in #7471.
Some things to note:
- I added support for individual packages — I didn't think there was a
good reason for ```--python``` to only apply to all packages
- Upgrading with ```--python``` also upgrades the package itself — I
think this is fair as if a user wants to _strictly_ switch the version
of Python being used to build a tool's environment they can use ```uv
install```. This behavior can of course be modified if others don't
agree!
Closes https://github.com/astral-sh/uv/issues/6297.
Closes https://github.com/astral-sh/uv/issues/7471.
## 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.
Recently, rkyv 0.8 was released. Its API is a fair bit simpler now for
higher level uses (like for us in `uv`) and results in us being able to
delete a fair bit of code. This also removes our last dependency on `syn
1.0`, and thus drops that dependency.
Performance (via testing on the `transformers` example) seems to remain
about the same, which is what was expected:
```
$ hyperfine -w5 -r100 'uv lock' 'uv-ag-rkyv-update lock'
Benchmark 1: uv lock
Time (mean ± σ): 55.6 ms ± 6.4 ms [User: 30.4 ms, System: 35.1 ms]

Benchmark 2: uv-ag-rkyv-update lock
Time (mean ± σ): 56.5 ms ± 7.2 ms [User: 30.5 ms, System: 36.3 ms]
Range (min … max): 39.1 ms … 71.5 ms 100 runs
Summary
uv lock ran
1.02 ± 0.18 times faster than uv-ag-rkyv-update lock
```
Closes#7415

```

```
So need some input on whether it's worth supporting.
Closes https://github.com/astral-sh/uv/issues/7484.
## Summary
Since https://github.com/astral-sh/uv/pull/7208, this is now _always_
firing, for every directory, because the version gets normalized (e.g.,
`1.2.3` gets normalized to `1-2-3`, which never matches the parsed
version). pip doesn't warn here, I guess we won't either, because I
can't figure out a robust way to do this... We need to get the
non-normalized remainder after stripping the normalized package name,
but we strip the normalized package name from the normalized string, so
we only have a normalized remainder.
We got user reports where users were confused about why they can't use
`[project.urls]` in `pyproject.toml` (i think that's from poetry?). This
PR adds a hint that (according to PEP 621), you need to set
`project.name` when using any `project` fields. (PEP 621 also requires
`project.version` xor `dynamic = ["version"]`, but we check that later.)
The intermediate parsing layer to tell apart syntax errors from schema
errors doesn't incur a performance penalty according to epage
(https://github.com/toml-rs/toml/issues/778#issuecomment-2310369253).
Closes#6419Closes#6760

This has been asked for a few times. There are risks that these checks
could be slow, but they're buyer-beware.

## Summary

error if we only have a source distribution for a given package when
`--no-build` is provided but that package is _omitted_.

## Summary
Replace the unmaintained `tokio-tar` crate with the `krata-tokio-tar`
fork. The latter just merged a fix necessary for the crate to work on
PowerPC, and has better chances of future maintenance.
Fixes#3423
## Test Plan
`cargo test`
This is preparatory work for the upload functionality, which needs to
read the METADATA file and attach its parsed contents to the POST
request: We move finding the `.dist-info` from `install-wheel-rs` and
`uv-client` to a new `uv-metadata` crate, so it can be shared with the
publish crate.
I don't properly know if its the right place since the upload code isn't
ready, but i'm PR-ing it now because it already had merge conflicts.
## Summary
If `--config-settings` are provided, we cache the built wheels under one
more subdirectory.
We _don't_ invalidate the actual source (i.e., trigger a re-download) or
metadata, though -- those can be reused even when `--config-settings`
change.
Closes https://github.com/astral-sh/uv/issues/7028.
## Summary
This PR adds a more flexible cache invalidation abstraction for uv, and
uses that new abstraction to improve support for dynamic metadata.
Specifically, instead of relying solely on a timestamp, we now pass
around a `CacheInfo` struct which (as of now) contains
`Option<Timestamp>` and `Option<Commit>`. The `CacheInfo` is saved in
`dist-info` as `uv_cache.json`, so we can test already-installed
distributions for cache validity (along with testing _cached_
distributions for cache validity).
Beyond the defaults (`pyproject.toml`, `setup.py`, and `setup.cfg`
changes), users can also specify additional cache keys, and it's easy
for us to extend support in the future. Right now, cache keys can either
be instructions to include the current commit (for `setuptools_scm` and
similar) or file paths (for `hatch-requirements-txt` and similar):
```toml
[tool.uv]
cache-keys = [{ file = "requirements.txt" }, { git = true }]
```
This change should be fully backwards compatible.

## Summary
We now track the discovered `IndexCapabilities` for each `IndexUrl`. If
we learn that an index doesn't support range requests, we avoid doing
any batch prefetching.
Closes https://github.com/astral-sh/uv/issues/7221.
## Summary
We were only applying exclusions when discovering the root, apparently.
Our logic now matches the original intent, which is...
- `exclude` always post-filters `members`.
- We don't treat globs any differently than non-globs.
The one confusing setup that falls out of this is that given:
```toml
members = ["foo/bar/baz"]
exclude = ["foo/bar"]
```
`foo/bar/baz` **would** be included. To exclude it, you would need:
```toml
members = ["foo/bar/baz"]
exclude = ["foo/bar/*"]
```
Closes https://github.com/astral-sh/uv/issues/7071.
(This is part of #5711)
## Summary
@BurntSushi and I spotted that the `derivative` crate is only used for
one enum in the entire codebase — however, it's a proc macro, and we pay
for the cost of (re)compiling it in many different contexts.
This replaces it with a private `Inner` core which uses the regular std
derive macros — inlining and optimizations should make this equivalent
to the other implementation, and not too hard to maintain hopefully
(versus a manual impl of `PartialEq` and `Hash` which have to be kept in
sync.)
## Test Plan
Trust CI?
## Summary
This has bothered me for a while and should be fairly impactful for
users. It requires a weird implementation, since the
distribution-building crate depends on the cache, and so the prune
operation can't live in the cache, since it needs to access internals of
the distribution-building crate.
Closes https://github.com/astral-sh/uv/issues/7096.
## Summary
This PR exposes uv's PEP 517 implementation via a `uv build` frontend,
such that you can use `uv build` to build source and binary
distributions (i.e., wheels and sdists) from a given directory.
There are some TODOs that I'll tackle in separate PRs:
- [x] Support building a wheel from a source distribution (rather than
from source) (#6898)
- [x] Stream the build output (#6912)
Closes https://github.com/astral-sh/uv/issues/1510
Closes https://github.com/astral-sh/uv/issues/1663.
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.

## 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
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
Fixes: #6615
Currently, some packages are not installable with `uv`, like `ziglang`
on Linux.
Everything is described in the issue! 😄
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
<!-- How was it tested? -->
I added a unit test for the problematic use case.
I also checked that previous unit test are still running in order to
ensure the backward compatibility.
For users who were using absolute paths in the `pyproject.toml`
previously, this is a behavior change: We now convert all absolute paths
in `path` entries to relative paths. Since i assume that no-one relies
on absolute path in their lockfiles - they are intended to be portable -
I'm tagging this as a bugfix.
Closes https://github.com/astral-sh/uv/pull/6438
Fixes https://github.com/astral-sh/uv/issues/6371
The ADD `MarkerTree` was including the non-deterministic, unstable
`NodeId` in its `Ord` implementation since switching algebraic decision
diagrams. By replacing this with a correct `Ord` implementation, we fix
#6249.
Requires https://github.com/astral-sh/pubgrub/pull/31
This PR moves us to the Linux strategy for our global directories on
macOS. We both feel on the team _and_ have received feedback (in Issues
and Polls) that the `Application Support` directories are more intended
for GUIs, and CLI tools are correct to respect the XDG variables and use
the same directory paths on Linux and macOS.
Namely, we now use:
- `/Users/crmarsh/.local/share/uv/tools` (for tools)
- `/Users/crmarsh/.local/share/uv/python` (for Pythons)
- `/Users/crmarsh/.cache/uv` (for the cache)
The strategy is such that if the `/Users/crmarsh/Library/Application
Support/uv` already exists, we keep using it -- same goes for
`/Users/crmarsh/Library/Caches/uv`, so **it's entirely backwards
compatible**.
If you want to force a migration to the new schema, you can run:
- `uv cache clean`
- `uv tool uninstall --all`
- `uv python uninstall --all`
Which will clean up the macOS-specific directories, paving the way for
the above paths. In other words, once you run those commands, subsequent
`uv` operations will automatically use the `~/.cache` and `~/.local`
variants.
Closes https://github.com/astral-sh/uv/issues/4411.

- Removes "experimental" labels from command documentation
- Removes preview warnings
- Removes `PreviewMode` from most structs and methods — we could keep it
around but I figure we can propagate it again easily where needed in the
future
- Enables preview behavior by default everywhere, e.g., `uv venv` will
download Python versions
This PR migrates uv's use of `chrono` to `jiff`.
I did most of this work a while back as one of my tests to ensure Jiff
could actually be used in a real world project. I decided to revive
this because I noticed that `reqwest-retry` dropped its Chrono
dependency,
which is I believe the only other thing requiring Chrono in uv.
(Although, we use a fork of `reqwest-middleware` at present, and that
hasn't been updated to latest upstream yet. I wasn't quite sure of the
process we have for that.)
In course of doing this, I actually made two changes to uv:
First is that the lock file now writes an RFC 3339 timestamp for
`exclude-newer`. Previously, we were using Chrono's `Display`
implementation for this which is a non-standard but "human readable"
format. I think the right thing to do here is an RFC 3339 timestamp.
Second is that, in addition to an RFC 3339 timestamp, `--exclude-newer`
used to accept a "UTC date." But this PR changes it to a "local date."
That is, a date in the user's system configured time zone. I think
this makes more sense than a UTC date, but one alternative is to drop
support for a date and just rely on an RFC 3339 timestamp. The main
motivation here is that automatically assuming UTC is often somewhat
confusing, since just writing an unqualified date like `2024-08-19` is
often assumed to be interpreted relative to the writer's "local" time.
## Summary
We retain them if you use `--raw-sources`, but otherwise they're
removed. We still respect them in the subsequent `uv.lock` via an
in-process store.
Closes#6056.
## Summary
Added the actual error message to the warning when uv fails to parse
`pyproject.toml`.
Resolves https://github.com/astral-sh/uv/issues/5934
## Test Plan
Took the case from the issue:
- have `pyproject.toml` which contains
```
[tool.uv]
foobar = false
```
-
```
$ uv venv --preview -v
```
- Expect the message that contains the actual problem in the
`pyproject.toml` like:
```
warning: Failed to parse `pyproject.toml` during settings discovery: unknown field `foobar`; skipping...
```
## Summary
We now persist the `ResolverInstallerOptions` when writing out a tool
receipt. When upgrading, we grab the saved options, and merge with the
command-line arguments and user-level filesystem settings (CLI > receipt
> filesystem).
## Summary
This PR rewrites the `MarkerTree` type to use algebraic decision
diagrams (ADD). This has many benefits:
- The diagram is canonical for a given marker function. It is impossible
to create two functionally equivalent marker trees that don't refer to
the same underlying ADD. This also means that any trivially true or
unsatisfiable markers are represented by the same constants.
- The diagram can handle complex operations (conjunction/disjunction) in
polynomial time, as well as constant-time negation.
- The diagram can be converted to a simplified DNF form for user-facing
output.
The new representation gives us a lot more confidence in our marker
operations and simplification, which is proving to be very important
(see https://github.com/astral-sh/uv/pull/5733 and
https://github.com/astral-sh/uv/pull/5163).
Unfortunately, it is not easy to split this PR into multiple commits
because it is a large rewrite of the `marker` module. I'd suggest
reading through the `marker/algebra.rs`, `marker/simplify.rs`, and
`marker/tree.rs` files for the new implementation, as well as the
updated snapshots to verify how the new simplification rules work in
practice. However, a few other things were changed:
- [We now use release-only comparisons for `python_full_version`, where
we previously only did for
`python_version`](https://github.com/astral-sh/uv/blob/ibraheem/canonical-markers/crates/pep508-rs/src/marker/algebra.rs#L522).
I'm unsure how marker operations should work in the presence of
pre-release versions if we decide that this is incorrect.
- [Meaningless marker expressions are now
ignored](https://github.com/astral-sh/uv/blob/ibraheem/canonical-markers/crates/pep508-rs/src/marker/parse.rs#L502).
This means that a marker such as `'x' == 'x'` will always evaluate to
`true` (as if the expression did not exist), whereas we previously
treated this as always `false`. It's negation however, remains `false`.
- [Unsatisfiable markers are written as `python_version <
'0'`](https://github.com/astral-sh/uv/blob/ibraheem/canonical-markers/crates/pep508-rs/src/marker/tree.rs#L1329).
- The `PubGrubSpecifier` type has been moved to the new `uv-pubgrub`
crate, shared by `pep508-rs` and `uv-resolver`. `pep508-rs` also depends
on the `pubgrub` crate for the `Range` type, we probably want to move
`pubgrub::Range` into a separate crate to break this, but I don't think
that should block this PR (cc @konstin).
There is still some remaining work here that I decided to leave for now
for the sake of unblocking some of the related work on the resolver.
- We still use `Option<MarkerTree>` throughout uv, which is unnecessary
now that `MarkerTree::TRUE` is canonical.
- The `MarkerTree` type is now interned globally and can potentially
implement `Copy`. However, it's unclear if we want to add more
information to marker trees that would make it `!Copy`. For example, we
may wish to attach extra and requires-python environment information to
avoid simplifying after construction.
- We don't currently combine `python_full_version` and `python_version`
markers.
- I also have not spent too much time investigating performance and
there is probably some low-hanging fruit. Many of the test cases I did
run actually saw large performance improvements due to the markers being
simplified internally, reducing the stress on the old `normalize`
routine, especially for the extremely large markers seen in
`transformers` and other projects.

https://github.com/astral-sh/uv/issues/5179.
## 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
The current receipt doesn't capture quite enough information. For
example, it doesn't differentiate between editable and non-editable
requirements. This PR instead uses the full `Requirement` type. I think
we should use a custom representation like we do in the lockfile, but
I'm just using the default representation to demonstrate the idea.

## Summary
Closes#2187.
The [xz
backdoor](https://gist.github.com/thesamesam/223949d5a074ebc3dce9ee78baad9e27)
is still fairly recent, but luckily the [Rust `xz2` crate bundles
version 5.2.5 of the C `xz`
package](https://github.com/alexcrichton/xz2-rs/tree/main/lzma-sys),
which is before the backdoor was introduced.
It's worth noting that a security risk still exists if you have a
compromised version of `xz` installed on your system, but that risk is
not introduced by `uv` or the Rust packages in general.
## Test Plan
Tried installing the package mentioned in the linked issue: `python-apt
@
https://launchpad.net/ubuntu/+archive/primary/+sourcefiles/python-apt/2.7.6/python-apt_2.7.6.tar.xz`
(Note that this will only work on Ubuntu - I tried on a Mac and while
the archive was extracted properly, the package did not install because
of some missing files)

## Summary
It's hard for me to imagine a scenario in which a user passed
`--reinstall`, but wanted us to keep respecting cached data for a
package. For example, to actually "rebuild and reinstall" an editable
today, you have to pass both `--reinstall` and `--refresh`.
This PR makes `--reinstall` imply `--refresh`, so we always validate
that the cached data is fresh.

## Summary
I don't think that "always reinstall" is tenable for `uv run`. My
perspective on this is that if you want "always reinstall", you can now
set it persistently in your `pyproject.toml` or `uv.toml`.
As a smaller change, we could instead disable this _only_ for the
Project API.
Closes https://github.com/astral-sh/uv/issues/4946.
## Summary
Implements the `uv init` command, which initializes a project
(`pyproject.toml`, `README.md`, `src/__init__.py`) in the current
directory, or in the given path. `uv init` also does workspace
discovery.

## Summary
Makes the `tools()` return value include per-tool errors. This makes it
easy to skip (rather than failing) in `uv tool list`, _and_ improves `uv
tool uninstall` to remove those invalid tools, rather than leaving them
around. (We already had that behavior for `uv tool uninstall ruff` with
an invalid `ruff`, but `uv tool uninstall --all` just left them.)
Closes https://github.com/astral-sh/uv/issues/5151.
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
Workaround the `stream_wheel` not retry issue
[found](https://github.com/astral-sh/uv/issues/3514#issuecomment-2229820667)
in #3514, it's not a perfect solution but I think it's acceptable
because the error should not occur frequently.
## Test Plan
Manually using `iptables -A OUTPUT -p tcp -dport 3128 -j REJECT
--reject-with tcp-reset` to inject connection reset error to the HTTP
proxy that proxies PyPI requests.
```
error: Failed to prepare distributions
Caused by: Failed to fetch wheel: piqp==0.4.1

Caused by: client error (Connect)
Caused by: tcp connect error: Connection refused (os error 111)
Caused by: Connection refused (os error 111)
```
The only pubgrub error that can occur is a `NoSolutionError`, and the
only place it can occur is `unit_propagation`, all other variants if
`PubGrubError` are unreachable. By changing the return type on pubgrub's
side (https://github.com/astral-sh/pubgrub/pull/28), we can remove the
pattern matching and the `unreachable!()` asserts on `PubGrubError`.
Our pubgrub error wrapper used to have a two phased initialization,
first mostly stubs in `solve[_tracked]()` and then adding the actual
context in `resolve()`. When constructing the error in `solve` we
already have all this context, so we can unify this to a regular
constructor and remove the special casing in `resolve()` and `hints()`.
## Summary
Largely based on rustup's implementation (linked in the source).
Closes#5027.
## Test Plan
- Changed the executable directory to `uv/foo`.
- Ran script; verified that I could access executables in `foo`.
## Summary
I'll open follow-up tickets for Windows support.

## 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.

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.
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)
## 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
Packages that provide scripts that _aren't_ Python entrypoints need to
respected in `uv tool install`. For example, Ruff ships a script in
`ruff-0.5.0.data/scripts`.
Unfortunately, the `.data` directory doesn't exist in the virtual
environment at all (it's removed, per the spec, after install). So this
PR changes the entry point detection to look at the `RECORD` file, which
is the only evidence that the scripts were installed.
Closes https://github.com/astral-sh/uv/issues/4691.
## Test Plan
`cargo run uv tool install ruff` (snapshot tests to-come)
