## Summary
Follow-up to #16035.
`check_docs_formatted.py` will now report backtick-quoted shortcut links
in rule documentation. It uses a regular expression to find them. Such a
link:
* Starts with `[`, followed by <code>\`</code>, then a "name" sequence
of at least one non-backtick non-newline character, followed by another
<code>\`</code>, then ends with `]`.
* Is not followed by either a `[` or a `(`.
* Is not placed within a code block.
If the name is a known Ruff option name, that link is not considered a
violation.
## Test Plan
Manual.
## Summary
Rome Tools Playground was renamed to Biome Playground. The link was
replaced to the new website.
Resolves#16143
## Test Plan
- Checked the linked is accessible from the README
## Summary
Resolves#13294, follow-up to #13882.
At #13882, it was concluded that a fix should not be offered for raw
strings. This change implements that. The five rules in question are now
no longer always fixable.
## Test Plan
`cargo nextest run` and `cargo insta test`.

Follow-up to https://github.com/astral-sh/ruff/pull/15951 to update
* the options links in A005 to reference
`lint.flake8-builtins.builtins-strict-checking`
* the description of the rule to explain strict vs non-strict checking
* the option documentation to point back to the rule
For now, the only thing one can configure is whether color is enabled or
not. This avoids needing to ask the `colored` crate whether colors have
been globally enabled or disabled. And, more crucially, avoids the need
to _set_ this global flag for testing diagnostic output. Doing so can
have unintended consequences, as outlined in #16115.
Fixes#16115
## Summary
Add support for the `project.requires-python` field in `pyproject.toml`
files.
Fall back to the resolved lower bound of `project.requires-python` if
the `environment.python-version` field is `None` (or more accurately,
initialize `environment.python-version with `requires-python`'s lower
bound if left unspecified).
## UX design
There are two options on how we can handle the fallback to
`requires-python`'s lower bound:
1. Store the resolved lower bound in `environment.python-version` if
that field is `None` (Implemented in this PR)
2. Store the `requires-python` constraint separately.
There's no observed difference unless a user-level configuration (or any
other inherited configuration is used). Let's discuss it on the given
example
**User configuration**
```toml
[environment]
python-version = "3.10"
```
**Project configuration (`pyproject.toml`)**
```toml
[project]
name = "test"
requires-python = ">= 3.12"
[tool.knot]
# No environment table
```
The resolved version for 1. is 3.12 because the `requires-python`
constraint precedence takes precedence over the `python-version` in the
user configuration. 2. resolves to 3.10 because all `python-version`
constraints take precedence before falling back to `requires-python`.
Ruff implements 1. It's also the easier to implement and it does seem
intuitive to me that the more local `requires-python` constraint takes
precedence.
## Test plan
Added CLI and unit tests.
The PR addresses the issue #16040 .
---
The logic used into the rule is the following:
Suppose to have an expression of the form
```python
if a cmp b:
c = d
```
where `a`,` b`, `c` and `d` are Python obj and `cmp` one of `<`, `>`,
`<=`, `>=`.
Then:
- `if a=c and b=d`
- if `<=` fix with `a = max(b, a)`
- if `>=` fix with `a = min(b, a)`
- if `>` fix with `a = min(a, b)`
- if `<` fix with `a = max(a, b)`
- `if a=d and b=c`
- if `<=` fix with `b = min(a, b)`
- if `>=` fix with `b = max(a, b)`
- if `>` fix with `b = max(b, a)`
- if `<` fix with `b = min(b, a)`
- do nothing, i.e., we cannot fix this case.
---
In total we have 8 different and possible cases.
```
| Case | Expression | Fix |
|-------|------------------|---------------|
| 1 | if a >= b: a = b | a = min(b, a) |
| 2 | if a <= b: a = b | a = max(b, a) |
| 3 | if a <= b: b = a | b = min(a, b) |
| 4 | if a >= b: b = a | b = max(a, b) |
| 5 | if a > b: a = b | a = min(a, b) |
| 6 | if a < b: a = b | a = max(a, b) |
| 7 | if a < b: b = a | b = min(b, a) |
| 8 | if a > b: b = a | b = max(b, a) |
```
I added them in the tests.
Please double-check that I didn't make any mistakes. It's quite easy to
mix up > and <.

## Summary
After I was asked twice within the same day, I thought it would be a
good idea to write some *user facing* documentation that explains our
reasoning behind inferring `Unknown | T_inferred` for public uses of
undeclared symbols. This is a major deviation from the behavior of other
type checkers and it seems like a good practice to defend our choice
like this.
## Summary
* fix ImportPathMoved / ProviderName misuse
* oncrete names, such as `["airflow", "config_templates",
"default_celery", "DEFAULT_CELERY_CONFIG"]`, should use `ProviderName`.
In contrast, module paths like `"airflow", "operators", "weekday", ...`
should use `ImportPathMoved`. Misuse may lead to incorrect detection.
## Test Plan
update test fixture
This essentially makes it impossible to construct a `Diagnostic`
that has a `TextRange` but no `File`.
This is meant to be a precursor to multi-span support.
(Note that I consider this more of a prototyping-change and not
necessarily what this is going to look like longer term.)
Reviewers can probably review this PR as one big diff instead of
commit-by-commit.
## Summary
This is a follow up to
https://github.com/astral-sh/ruff/pull/15763#discussion_r1949681336
It reverts the change to using ptr equality for `AstNodeRef`s, which in
turn removes the `Eq`, `PartialEq`, and `Hash` implementations for
`AstNodeRef`s parametrized with AST nodes.
Cheap comparisons shouldn't be needed because the node field is
generally marked as `[#tracked]` and `#[no_eq]` and removing the
implementations even enforces that those
attributes are set on all `AstNodeRef` fields (which is good).
The only downside this has is that we technically wouldn't have to mark
the `Unpack::target` as `#[tracked]` because
the `target` field is accessed in every query accepting `Unpack` as an
argument.
Overall, enforcing the use of `#[tracked]` seems like a good trade off,
espacially considering that it's very likely that
we'd probably forget to mark the `Unpack::target` field as tracked if we
add a new `Unpack` query that doesn't access the target.
## Test Plan
`cargo test`
## Summary
Fixes#16007. The logic from the last fix for this (#9427) was
sufficient, it just wasn't being applied because `Attributes` sections
aren't expected to have nested sections. I just deleted the outer
conditional, which should hopefully fix this for all section types.
## Test Plan
New regression test, plus the existing D417 tests.
## Summary
Transition to using coarse-grained tracked structs (depends on
https://github.com/salsa-rs/salsa/pull/657). For now, this PR doesn't
add any `#[tracked]` fields, meaning that any changes cause the entire
struct to be invalidated. It also changes `AstNodeRef` to be
compared/hashed by pointer address, instead of performing a deep AST
comparison.
## Test Plan
This yields a 10-15% improvement on my machine (though weirdly some runs
were 5-10% without being flagged as inconsistent by criterion, is there
some non-determinism involved?). It's possible that some of this is
unrelated, I'll try applying the patch to the current salsa version to
make sure.

## Summary
Resolves#16082.
`UP036` will now also take into consideration whether or not a micro
version number is set:
* If a third element doesn't exist, the existing logic is preserved.
* If it exists but is not an integer literal, the check will not be
reported.
* If it is an integer literal but doesn't fit into a `u8`, the check
will be reported as invalid.
* Otherwise, the compared version is determined to always be less than
the target version when:
* The target's minor version is smaller than that of the comparator, or
* The operator is `<`, the micro version is 0, and the two minor
versions compare equal.
As this is considered a bugfix, it is not preview-gated.
## Test Plan
`cargo nextest run` and `cargo insta test`.

## Summary
- Simplify unions with `object` to `object`.
- Add a new `Type::object(db)` constructor to abbreviate
`KnownClass::Object.to_instance(db)` in some places.
- Add a `Type::is_object` and `Class::is_object` function to make some
tests for a bit easier to read.
closes#16084
## Test Plan
New Markdown tests.
The index in subscript access like `d[*y]` will not be linted or
autofixed with parentheses, even when
`lint.ruff.parenthesize-tuple-in-subscript = true`.
Closes#16077
## Summary
This PR adds support for user-level configurations
(`~/.config/knot/knot.toml`) to Red Knot.
Red Knot will watch the user-level configuration file for changes but
only if it exists
when the process start. It doesn't watch for new configurations,
mainly to simplify things for now (it would require watching the entire
`.config` directory because the `knot` subfolder might not exist
either).
The new `ConfigurationFile` struct seems a bit overkill for now but I
plan to use it for
hierarchical configurations as well.
Red Knot uses the same strategy as uv and Ruff by using the etcetera
crate.
## Test Plan
Added CLI and file watching test
## Summary
This PR adds a new `user_configuration_directory` method to `System`. We
need it to resolve where to lookup a user-level `knot.toml`
configuration file.
The method belongs to `System` because not all platforms have a
convention of where to store such configuration files (e.g. wasm).
I refactored `TestSystem` to be a simple wrapper around an `Arc<dyn
System...>` and use the `System.as_any` method instead to cast it down
to an `InMemory` system. I also removed some `System` specific methods
from `InMemoryFileSystem`, they don't belong there.
This PR removes the `os` feature as a default feature from `ruff_db`.
Most crates depending on `ruff_db` don't need it because they only
depend on `System` or only depend on `os` for testing. This was
necessary to fix a compile error with `red_knot_wasm`
## Test Plan
I'll make use of the method in my next PR. So I guess we won't know if
it works before then but I copied the code from Ruff/uv, so I have high
confidence that it is correct.
`cargo test`
## Summary
This PR generalize the idea that we may want to emit diagnostics for
invalid or incompatible configuration values similar to how we already
do it for `rules`.
This PR introduces a new `Settings` struct that is similar to `Options`
but, unlike
`Options`, are fields have their default values filled in and they use a
representation optimized for reads.
The diagnostics created during loading the `Settings` are stored on the
`Project` so that we can emit them when calling `check`.
The motivation for this work is that it simplifies adding new settings.
That's also why I went ahead and added the `terminal.error-on-warning`
setting to demonstrate how new settings are added.
## Test Plan
Existing tests, new CLI test.
## Summary
Revert the v4 update for now until the codebase is updated
(https://github.com/astral-sh/ruff/pull/16069).
Update renovate config to disable updating it.
## Test Plan
```console

## Summary
Follow-up to #15984.
Previously, `PLE1310` would only report when the object is a literal:
```python
'a'.strip('//') # error
foo = ''
foo.strip('//') # no error
```
After this change, objects whose type can be inferred to be either `str`
or `bytes` will also be reported in preview.

### Release Notes
<details>
<summary>rust-lang/rustc-hash (rustc-hash)</summary>
###
[`v2.1.1`](https://redirect.github.com/rust-lang/rustc-hash/blob/HEAD/CHANGELOG.md#211)
[Compare
Source](https://redirect.github.com/rust-lang/rustc-hash/compare/v2.1.0...v2.1.1)
- Change the internal algorithm to better accomodate large hashmaps.
This mitigates a [regression with 2.0 in
rustc](https://redirect.github.com/rust-lang/rust/issues/135477).
See [PR#55](https://redirect.github.com/rust-lang/rustc-hash/pull/55)
for more details on the change (this PR was not merged).
This problem might be improved with changes to hashbrown in the future.
#### 2.1.0
- Implement `Clone` for `FxRandomState`
- Implement `Clone` for `FxSeededState`
- Use SPDX license expression in license field
#### 2.0.0
- Replace hash with faster and better finalized hash.
This replaces the previous "fxhash" algorithm originating in Firefox
with a custom hasher designed and implemented by Orson Peters
([`@orlp`](https://redirect.github.com/orlp)).
It was measured to have slightly better performance for rustc, has
better theoretical properties
and also includes a significantly better string hasher.
- Fix `no_std` builds
#### 1.2.0 (**YANKED**)
**Note: This version has been yanked due to issues with the `no_std`
feature!**
- Add a `FxBuildHasher` unit struct
- Improve documentation
- Add seed API for supplying custom seeds other than 0
- Add `FxRandomState` based on `rand` (behind the `rand` feature) for
random seeds
- Make many functions `const fn`
- Implement `Clone` for `FxHasher` struct

## Summary
fixes: #16041
## Test Plan
Using the [project](https://github.com/bwcc-clan/polebot) in the linked
issue:
Notice how the project "polebot" is in the "play" directory which is
included in the `exclude` setting as:
```toml
exclude = ["play"]
```
**Before this fix**
```
DEBUG ruff:worker:0 ruff_server::resolve: Ignored path via `exclude`: /private/tmp/ruff-test/play/polebot/src/utils/log_tools.py
```
**After this fix**
```
DEBUG ruff:worker:2 ruff_server::resolve: Included path via `include`: /private/tmp/ruff-test/play/polebot/src/utils/log_tools.py
```
I also updated the same project to remove the "play" directory from the
`exclude` setting and made sure that anything under the `polebot/play`
directory is included:
```
DEBUG ruff:worker:4 ruff_server::resolve: Included path via `include`: /private/tmp/ruff-test/play/polebot/play/test.py
```
And, excluded when I add the directory back:
```
DEBUG ruff:worker:2 ruff_server::resolve: Ignored path via `exclude`: /private/tmp/ruff-test/play/polebot/play/test.py
```
## Summary
This PR refactors the `RuffSettings` struct to directly include the
resolved `Settings` instead of including the specific fields from it.
The server utilizes a lot of it already, so it makes sense to just
include the entire struct for simplicity.
### `Deref`
I implemented `Deref` on `RuffSettings` to return the `Settings` because
`RuffSettings` is now basically a wrapper around it with the config path
as the other field. This path field is only used for debugging
("printDebugInformation" command).
## Summary
This PR adds the configuration option
`lint.flake8-builtins.builtins-strict-checking`, which is used in A005
to determine whether the fully-qualified module name (relative to the
project root or source directories) should be checked instead of just
the final component as is currently the case.
As discussed in
https://github.com/astral-sh/ruff/issues/15399#issuecomment-2587017147,
the default value of the new option is `false` on preview, so modules
like `utils.logging` from the initial report are no longer flagged by
default. For non-preview the default is still strict checking.
## Test Plan
New A005 test module with the structure reported in #15399.
Fixes#15399
## Summary
Resolves#12321.
The physical-line-based `RUF054` checks for form feed characters that
are preceded by only tabs and spaces, but not any other characters,
including form feeds.
## Test Plan
`cargo nextest run` and `cargo insta test`.
