Updated implementation of https://github.com/astral-sh/ruff/pull/7369
which was left out in the cold.
This was motivated again following changes in #9691 and #9689 where we
could not test the changes without actually deprecating or removing
rules.
---
Follow-up to discussion in https://github.com/astral-sh/ruff/pull/7210
Moves integration tests from using rules that are transitively in
nursery / preview groups to dedicated test rules that only exist during
development. These rules always raise violations (they do not require
specific file behavior). The rules are not available in production or in
the documentation.
Uses features instead of `cfg(test)` for cross-crate support per
https://github.com/rust-lang/cargo/issues/8379
## Summary
We haven't found time to flip this on, so feels like it's best to remove
it for now -- can always restore from source when we get back to it.
## Summary
This PR modifies our `Cargo.toml` files to use workspace dependencies
for _all_ dependencies, rather than the status quo of sporadically
trying to use workspace dependencies for those dependencies that are
used across multiple crates. I find the current situation more confusing
and harder to manage, since we have a mix of workspace and crate-local
dependencies, whereas this setup consistently uses the same approach for
all dependencies.
The "wsl" crate was last touched in 2019, whereas the "is-wsl" crate was
last updated in 2023. Additionally, it is unclear whether the "wsl"
crate supports both WSL1 and WSL2 (which was announced in 2019), whereas
the "is-wsl" crate explicitly supports both WSL1 and WSL2.
The required code changes are minimal, since both crates provide only a
`is_wsl() -> bool` function.
## Summary
Adds support for sarif v2.1.0 output to cli, usable via the
output-format paramter.
`ruff . --output-format=sarif`
Includes a few changes I wasn't sure of, namely:
* Adds a few derives for Clone & Copy, which I think could be removed
with a little extra work as well.
## Test Plan
I built and ran this against several large open source projects and
verified that the output sarif was valid, using [Microsoft's SARIF
validator tool](https://sarifweb.azurewebsites.net/Validation)
I've also attached an output of the sarif generated by this version of
ruff on the main branch of django at commit: b287af5dc9
[django_main_b287af5dc9_sarif.json](https://github.com/astral-sh/ruff/files/13626222/django_main_b287af5dc9_sarif.json)
Note: this needs to be regenerated with the latest changes and
confirmed.
## Open Points
[ ] Convert to just using all Rules all the time
[ ] Fix the issue with getting the file URI when compiling for web
assembly
Update to [Rust
1.74](https://blog.rust-lang.org/2023/11/16/Rust-1.74.0.html) and use
the new clippy lints table.
The update itself introduced a new clippy lint about superfluous hashes
in raw strings, which got removed.
I moved our lint config from `rustflags` to the newly stabilized
[workspace.lints](https://doc.rust-lang.org/stable/cargo/reference/workspaces.html#the-lints-table).
One consequence is that we have to `unsafe_code = "warn"` instead of
"forbid" because the latter now actually bans unsafe code:
```
error[E0453]: allow(unsafe_code) incompatible with previous forbid
--> crates/ruff_source_file/src/newlines.rs:62:17
|
62 | #[allow(unsafe_code)]
| ^^^^^^^^^^^ overruled by previous forbid
|
= note: `forbid` lint level was set on command line
```

## Summary
This PR implements a variety of optimizations to improve performance of
the Eradicate rule, which always shows up in all-rules benchmarks and
bothers me. (These improvements are not hugely important, but it was
kind of a fun Friday thing to spent a bit of time on.)
The improvements include:
- Doing cheaper work first (checking for some explicit substrings
upfront).
- Using `aho-corasick` to speed an exact substring search.
- Merging multiple regular expressions using a `RegexSet`.
- Removing some unnecessary `\s*` and other pieces from the regular
expressions (since we already trim strings before matching on them).
## Test Plan
I benchmarked this function in a standalone crate using a variety of
cases. Criterion reports that this version is up to 80% faster, and
almost every case is at least 50% faster:

## Summary
This is a follow-up to #7469 that attempts to achieve similar gains, but
without introducing malachite. Instead, this PR removes the `BigInt`
type altogether, instead opting for a simple enum that allows us to
store small integers directly and only allocate for values greater than
`i64`:
```rust
/// A Python integer literal. Represents both small (fits in an `i64`) and large integers.
#[derive(Clone, PartialEq, Eq, Hash)]
pub struct Int(Number);
#[derive(Debug, Clone, PartialEq, Eq, Hash)]
pub enum Number {
/// A "small" number that can be represented as an `i64`.
Small(i64),
/// A "large" number that cannot be represented as an `i64`.
Big(Box<str>),
}
impl std::fmt::Display for Number {
fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result {
match self {
Number::Small(value) => write!(f, "{value}"),
Number::Big(value) => write!(f, "{value}"),
}
}
}
```
We typically don't care about numbers greater than `isize` -- our only
uses are comparisons against small constants (like `1`, `2`, `3`, etc.),
so there's no real loss of information, except in one or two rules where
we're now a little more conservative (with the worst-case being that we
don't flag, e.g., an `itertools.pairwise` that uses an extremely large
value for the slice start constant). For simplicity, a few diagnostics
now show a dedicated message when they see integers that are out of the
supported range (e.g., `outdated-version-block`).
An additional benefit here is that we get to remove a few dependencies,
especially `num-bigint`.
