wip

## Summary

This PR avoids the `Vec::retain` call in `check_tokens` by checking if
rules are enabled as their diagnostics are constructed.


2a425e43fd/crates/ruff_linter/src/checkers/tokens.rs (L174-L176)

Since `LintContext::report_diagnostic_if_enabled` required a
`LinterSettings`, I added a `settings` field to the context itself
instead of trying to pass it everywhere. This also turned
`LogicalLinesContext` into a trivial wrapper around `LintContext`, so I
just removed it in favor of using `LintContext` directly too.

The diff is a bit smaller with whitespace hidden since many blocks got
moved into something like this:

```rust
if let Some(mut diagnostic) = context.report_diagnostic.enabled(...) {
    // old code
}
```

 # Breaking Changes
 
+## 0.12.0
+
+- **Detection of more syntax errors**
+
+    Ruff now detects version-related syntax errors, such as the use of the `match`
+    statement on Python versions before 3.10, and syntax errors emitted by
+    CPython's compiler, such as irrefutable `match` patterns before the final
+    `case` arm.
+
+- **New default Python version handling for syntax errors**
+
+    Ruff will default to the _latest_ supported Python version (3.13) when
+    checking for the version-related syntax errors mentioned above to prevent
+    false positives in projects without a Python version configured. The default
+    in all other cases, like applying lint rules, is unchanged and remains at the
+    minimum supported Python version (3.9).
+
+- **Updated f-string formatting**
+
+    Ruff now formats multi-line f-strings with format specifiers to avoid adding a
+    line break after the format specifier. This addresses a change to the Python
+    grammar in version 3.13.4 that made such a line break a syntax error.
+
+- **`rust-toolchain.toml` is no longer included in source distributions**
+
+    The `rust-toolchain.toml` is used to specify a higher Rust version than Ruff's
+    minimum supported Rust version (MSRV) for development and building release
+    artifacts. However, when present in source distributions, it would also cause
+    downstream package maintainers to pull in the same Rust toolchain, even if
+    their available toolchain was MSRV-compatible.
+
+- **[`suspicious-xmle-tree-usage`](https://docs.astral.sh/ruff/rules/suspicious-xmle-tree-usage/)
+    (`S320`) has been removed**
+
 ## 0.11.0
 
 This is a follow-up to release 0.10.0. Because of a mistake in the release process, the `requires-python` inference changes were not included in that release. Ruff 0.11.0 now includes this change as well as the stabilization of the preview behavior for `PGH004`.

+# Changelog 0.10.x
+
+## 0.10.0
+
+Check out the [blog post](https://astral.sh/blog/ruff-v0.10.0) for a migration guide and overview of the changes!
+
+### Breaking changes
+
+See also, the "Remapped rules" section which may result in disabled rules.
+
+- **Changes to how the Python version is inferred when a `target-version` is not specified** ([#16319](https://github.com/astral-sh/ruff/pull/16319))
+
+    Because of a mistake in the release process, the `requires-python` inference changes are not included in this release and instead shipped as part of 0.11.0.
+    You can find a description of this change in the 0.11.0 section.
+
+- **Updated `TYPE_CHECKING` behavior** ([#16669](https://github.com/astral-sh/ruff/pull/16669))
+
+    Previously, Ruff only recognized typechecking blocks that tested the `typing.TYPE_CHECKING` symbol. Now, Ruff recognizes any local variable named `TYPE_CHECKING`. This release also removes support for the legacy `if 0:` and `if False:` typechecking checks. Use a local `TYPE_CHECKING` variable instead.
+
+- **More robust noqa parsing** ([#16483](https://github.com/astral-sh/ruff/pull/16483))
+
+    The syntax for both file-level and in-line suppression comments has been unified and made more robust to certain errors. In most cases, this will result in more suppression comments being read by Ruff, but there are a few instances where previously read comments will now log an error to the user instead. Please refer to the documentation on [_Error suppression_](https://docs.astral.sh/ruff/linter/#error-suppression) for the full specification.
+
+- **Avoid unnecessary parentheses around with statements with a single context manager and a trailing comment** ([#14005](https://github.com/astral-sh/ruff/pull/14005))
+
+    This change fixes a bug in the formatter where it introduced unnecessary parentheses around with statements with a single context manager and a trailing comment. This change may result in a change in formatting for some users.
+
+- **Bump alpine default tag to 3.21 for derived Docker images** ([#16456](https://github.com/astral-sh/ruff/pull/16456))
+
+    Alpine 3.21 was released in Dec 2024 and is used in the official Alpine-based Python images. Now the ruff:alpine image will use 3.21 instead of 3.20 and ruff:alpine3.20 will no longer be updated.
+
+### Deprecated Rules

+
+The following behaviors have been stabilized:
+

+# Changelog 0.11.x
+
+## 0.11.0
+
+This is a follow-up to release 0.10.0. Because of a mistake in the release process, the `requires-python` inference changes were not included in that release. Ruff 0.11.0 now includes this change as well as the stabilization of the preview behavior for `PGH004`.
+
+### Breaking changes
+
+- **Changes to how the Python version is inferred when a `target-version` is not specified** ([#16319](https://github.com/astral-sh/ruff/pull/16319))
+
+    In previous versions of Ruff, you could specify your Python version with:
+
+    - The `target-version` option in a `ruff.toml` file or the `[tool.ruff]` section of a pyproject.toml file.
+    - The `project.requires-python` field in a `pyproject.toml` file with a `[tool.ruff]` section.
+
+    These options worked well in most cases, and are still recommended for fine control of the Python version. However, because of the way Ruff discovers config files, `pyproject.toml` files without a `[tool.ruff]` section would be ignored, including the `requires-python` setting. Ruff would then use the default Python version (3.9 as of this writing) instead, which is surprising when you've attempted to request another version.
+
+    In v0.10, config discovery has been updated to address this issue:
+
+    - If Ruff finds a `ruff.toml` file without a `target-version`, it will check
+        for a `pyproject.toml` file in the same directory and respect its
+        `requires-python` version, even if it does not contain a `[tool.ruff]`
+        section.
+    - If Ruff finds a user-level configuration, the `requires-python` field of the closest `pyproject.toml` in a parent directory will take precedence.
+    - If there is no config file (`ruff.toml`or `pyproject.toml` with a
+        `[tool.ruff]` section) in the directory of the file being checked, Ruff will
+        search for the closest `pyproject.toml` in the parent directories and use its
+        `requires-python` setting.
+
+### Stabilization
+
+The following behaviors have been stabilized:
+
+- [`blanket-noqa`](https://docs.astral.sh/ruff/rules/blanket-noqa/) (`PGH004`): Also detect blanked file-level noqa comments (and not just line level comments).

+# Changelog 0.4.x
+
+## 0.4.0
+
+### A new, hand-written parser
+
+Ruff's new parser is **>2x faster**, which translates to a **20-40% speedup** for all linting and formatting invocations.
+There's a lot to say about this exciting change, so check out the [blog post](https://astral.sh/blog/ruff-v0.4.0) for more details!
+
+See [#10036](https://github.com/astral-sh/ruff/pull/10036) for implementation details.
+
+### A new language server in Rust
+
+With this release, we also want to highlight our new language server. `ruff server` is a Rust-powered language
+server that comes built-in with Ruff. It can be used with any editor that supports the [Language Server Protocol](https://microsoft.github.io/language-server-protocol/) (LSP).
+It uses a multi-threaded, lock-free architecture inspired by `rust-analyzer` and it will open the door for a lot
+of exciting features. It’s also faster than our previous [Python-based language server](https://github.com/astral-sh/ruff-lsp)
+-- but you probably guessed that already.
+
+`ruff server` is only in alpha, but it has a lot of features that you can try out today:
+
+- Lints Python files automatically and shows quick-fixes when available
+- Formats Python files, with support for range formatting
+- Comes with commands for quickly performing actions: `ruff.applyAutofix`, `ruff.applyFormat`, and `ruff.applyOrganizeImports`
+- Supports `source.fixAll` and `source.organizeImports` source actions
+- Automatically reloads your project configuration when you change it
+
+To setup `ruff server` with your editor, refer to the [README.md](https://github.com/astral-sh/ruff/blob/main/crates/ruff_server/README.md).

+# Changelog 0.7.x
+
+## 0.7.0
+
+Check out the [blog post](https://astral.sh/blog/ruff-v0.7.0) for a migration guide and overview of the changes!
+
+### Breaking changes
+
+- The pytest rules `PT001` and `PT023` now default to omitting the decorator parentheses when there are no arguments
+    ([#12838](https://github.com/astral-sh/ruff/pull/12838), [#13292](https://github.com/astral-sh/ruff/pull/13292)).
+    This was a change that we attempted to make in Ruff v0.6.0, but only partially made due to an error on our part.
+    See the [blog post](https://astral.sh/blog/ruff-v0.7.0) for more details.
+- The `useless-try-except` rule (in our `tryceratops` category) has been recoded from `TRY302` to
+    `TRY203` ([#13502](https://github.com/astral-sh/ruff/pull/13502)). This ensures Ruff's code is consistent with
+    the same rule in the [`tryceratops`](https://github.com/guilatrova/tryceratops) linter.
+- The `lint.allow-unused-imports` setting has been removed ([#13677](https://github.com/astral-sh/ruff/pull/13677)). Use
+    [`lint.pyflakes.allow-unused-imports`](https://docs.astral.sh/ruff/settings/#lint_pyflakes_allowed-unused-imports)
+    instead.
+
+### Formatter preview style

+

+    [`pydoclint`](https://docs.astral.sh/ruff/rules/#pydoclint-doc) diagnostics now point to the first-line of the problematic docstring. Previously, this was not the case.
+
+    If you've opted into these preview rules but have them suppressed using
+    [`noqa`](https://docs.astral.sh/ruff/linter/#error-suppression) comments in
+    some places, this change may mean that you need to move the `noqa` suppression
+    comments. Most users should be unaffected by this change.
+
+- **Use XDG (i.e. `~/.local/bin`) instead of the Cargo home directory in the standalone installer**
+
+    Previously, Ruff's installer used `$CARGO_HOME` or `~/.cargo/bin` for its target install directory. Now, Ruff will be installed into `$XDG_BIN_HOME`, `$XDG_DATA_HOME/../bin`, or `~/.local/bin` (in that order).
+
+    This change is only relevant to users of the standalone Ruff installer (using the shell or PowerShell script). If you installed Ruff using uv or pip, you should be unaffected.
+
+- **Changes to the line width calculation**
+
+    Ruff now uses a new version of the [unicode-width](https://github.com/unicode-rs/unicode-width) Rust crate to calculate the line width. In very rare cases, this may lead to lines containing Unicode characters being reformatted, or being considered too long when they were not before ([`E501`](https://docs.astral.sh/ruff/rules/line-too-long/)).

+# Changelog 0.9.x
+
+## 0.9.0
+
+Check out the [blog post](https://astral.sh/blog/ruff-v0.9.0) for a migration guide and overview of the changes!
+
+### Breaking changes
+
+Ruff now formats your code according to the 2025 style guide. As a result, your code might now get formatted differently. See the formatter section for a detailed list of changes.
+
+This release doesn’t remove or remap any existing stable rules.
+
+### Stabilization
+
+The following rules have been stabilized and are no longer in preview:
+
+- [`stdlib-module-shadowing`](https://docs.astral.sh/ruff/rules/stdlib-module-shadowing/) (`A005`).
+    This rule has also been renamed: previously, it was called `builtin-module-shadowing`.
+- [`builtin-lambda-argument-shadowing`](https://docs.astral.sh/ruff/rules/builtin-lambda-argument-shadowing/) (`A006`)
+- [`slice-to-remove-prefix-or-suffix`](https://docs.astral.sh/ruff/rules/slice-to-remove-prefix-or-suffix/) (`FURB188`)
+- [`boolean-chained-comparison`](https://docs.astral.sh/ruff/rules/boolean-chained-comparison/) (`PLR1716`)
+- [`decimal-from-float-literal`](https://docs.astral.sh/ruff/rules/decimal-from-float-literal/) (`RUF032`)
+- [`post-init-default`](https://docs.astral.sh/ruff/rules/post-init-default/) (`RUF033`)
+- [`useless-if-else`](https://docs.astral.sh/ruff/rules/useless-if-else/) (`RUF034`)
+
+The following behaviors have been stabilized:
+
+- [`pytest-parametrize-names-wrong-type`](https://docs.astral.sh/ruff/rules/pytest-parametrize-names-wrong-type/) (`PT006`): Detect [`pytest.parametrize`](https://docs.pytest.org/en/7.1.x/how-to/parametrize.html#parametrize) calls outside decorators and calls with keyword arguments.
+- [`module-import-not-at-top-of-file`](https://docs.astral.sh/ruff/rules/module-import-not-at-top-of-file/) (`E402`): Ignore [`pytest.importorskip`](https://docs.pytest.org/en/7.1.x/reference/reference.html#pytest-importorskip) calls between import statements.
+- [`mutable-dataclass-default`](https://docs.astral.sh/ruff/rules/mutable-dataclass-default/) (`RUF008`) and [`function-call-in-dataclass-default-argument`](https://docs.astral.sh/ruff/rules/function-call-in-dataclass-default-argument/) (`RUF009`): Add support for [`attrs`](https://www.attrs.org/en/stable/).
+- [`bad-version-info-comparison`](https://docs.astral.sh/ruff/rules/bad-version-info-comparison/) (`PYI006`): Extend the rule to check non-stub files.
+
+The following fixes or improvements to fixes have been stabilized:
+

+- [`duplicate-union-members`](https://docs.astral.sh/ruff/rules/duplicate-union-member/) (`PYI016`)
+
+### Formatter
+
+This release introduces the new 2025 stable style ([#13371](https://github.com/astral-sh/ruff/issues/13371)), stabilizing the following changes:
+
+- Format expressions in f-string elements ([#7594](https://github.com/astral-sh/ruff/issues/7594))
+- Alternate quotes for strings inside f-strings ([#13860](https://github.com/astral-sh/ruff/pull/13860))
+- Preserve the casing of hex codes in f-string debug expressions ([#14766](https://github.com/astral-sh/ruff/issues/14766))
+- Choose the quote style for each string literal in an implicitly concatenated f-string rather than for the entire string ([#13539](https://github.com/astral-sh/ruff/pull/13539))
+- Automatically join an implicitly concatenated string into a single string literal if it fits on a single line ([#9457](https://github.com/astral-sh/ruff/issues/9457))
+- Remove the [`ISC001`](https://docs.astral.sh/ruff/rules/single-line-implicit-string-concatenation/) incompatibility warning ([#15123](https://github.com/astral-sh/ruff/pull/15123))
+- Prefer parenthesizing the `assert` message over breaking the assertion expression ([#9457](https://github.com/astral-sh/ruff/issues/9457))
+- Automatically parenthesize over-long `if` guards in `match` `case` clauses ([#13513](https://github.com/astral-sh/ruff/pull/13513))
+- More consistent formatting for `match` `case` patterns ([#6933](https://github.com/astral-sh/ruff/issues/6933))
+- Avoid unnecessary parentheses around return type annotations ([#13381](https://github.com/astral-sh/ruff/pull/13381))
+- Keep the opening parentheses on the same line as the `if` keyword for comprehensions where the condition has a leading comment ([#12282](https://github.com/astral-sh/ruff/pull/12282))
+- More consistent formatting for `with` statements with a single context manager for Python 3.8 or older ([#10276](https://github.com/astral-sh/ruff/pull/10276))
+- Correctly calculate the line-width for code blocks in docstrings when using `max-doc-code-line-length = "dynamic"` ([#13523](https://github.com/astral-sh/ruff/pull/13523))
+
+### Preview features
+
+- \[`flake8-bugbear`\] Implement `class-as-data-structure` (`B903`) ([#9601](https://github.com/astral-sh/ruff/pull/9601))
+- \[`flake8-type-checking`\] Apply `quoted-type-alias` more eagerly in `TYPE_CHECKING` blocks and ignore it in stubs (`TC008`) ([#15180](https://github.com/astral-sh/ruff/pull/15180))
+- \[`pylint`\] Ignore `eq-without-hash` in stub files (`PLW1641`) ([#15310](https://github.com/astral-sh/ruff/pull/15310))
+- \[`pyupgrade`\] Split `UP007` into two individual rules: `UP007` for `Union` and `UP045` for `Optional` (`UP007`, `UP045`) ([#15313](https://github.com/astral-sh/ruff/pull/15313))
+- \[`ruff`\] New rule that detects classes that are both an enum and a `dataclass` (`RUF049`) ([#15299](https://github.com/astral-sh/ruff/pull/15299))
+- \[`ruff`\] Recode `RUF025` to `RUF037` (`RUF037`) ([#15258](https://github.com/astral-sh/ruff/pull/15258))
+
+### Rule changes
+
+- \[`flake8-builtins`\] Ignore [`stdlib-module-shadowing`](https://docs.astral.sh/ruff/rules/stdlib-module-shadowing/) in stub files(`A005`) ([#15350](https://github.com/astral-sh/ruff/pull/15350))

+
+### Server
+
+- Improve the observability by removing the need for the ["trace" value](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#traceValue) to turn on or off logging. The server logging is solely controlled using the [`logLevel` server setting](https://docs.astral.sh/ruff/editors/settings/#loglevel)
+    which defaults to `info`. This addresses the issue where users were notified about an error and told to consult the log, but it didn’t contain any messages. ([#15232](https://github.com/astral-sh/ruff/pull/15232))

+//! Infrastructure for benchmarking real-world Python projects.
+//!
+//! The module uses a setup similar to mypy primer's, which should make it easy
+//! to add new benchmarks for projects in [mypy primer's project's list](https://github.com/hauntsaninja/mypy_primer/blob/ebaa9fd27b51a278873b63676fd25490cec6823b/mypy_primer/projects.py#L74).
+//!
+//! The basic steps for a project are:
+//! 1. Clone or update the project into a directory inside `./target`. The commits are pinnted to prevent flaky benchmark results due to new commits.
+//! 2. For projects with dependencies, run uv to create a virtual environment and install the dependencies.
+//! 3. (optionally) Copy the entire project structure into a memory file system to reduce the IO noise in benchmarks.
+//! 4. (not in this module) Create a `ProjectDatabase` and run the benchmark.
