## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
`airflow.datasets.DatasetEvent` has been removed in 3 but `AssetEvent`
might be added in the future
## Test Plan
<!-- How was it tested? -->
update the test fixture and reorg in the second commit
## Summary
The original autofix for G004 was quietly dropping everything but the
f-string components of any implicit concatenation sequence; this
addresses that.
Side note: It looks like `f_strings` is a bit risky to use (since it
implicitly skips non-f-string parts); use iter and include implicitly
concatenated pieces. We should consider if it's worth having
(convenience vs. bit risky).
## Test Plan
```
cargo test -p ruff_linter
```
Backtest (run new testcases against previous implementation):
```
git checkout HEAD^ crates/ruff_linter/src/rules/flake8_logging_format/rules/logging_call.rs
cargot test -p ruff_linter
```
Summary

Closes#19467 and also removes the warning about using Python 3.14
without
preview enabled.
I also bumped `PythonVersion::default` to 3.9 because it reaches EOL
this month,
but we could also defer that for now if we wanted.
The first three commits are related to the `latest` bump to 3.14; the
fourth commit
bumps the default to 3.10.
Note that this PR also bumps the default Python version for ty to 3.10
because
there was a test asserting that it stays in sync with
`ast::PythonVersion`.
Test Plan
--
Existing tests
I spot-checked the ecosystem report, and I believe these are all
expected. Inbits doesn't specify a target Python version, so I guess
we're applying the default. UP007, UP035, and UP045 all use the new
default value to emit new diagnostics.
## Summary
Fixes#20700
`else` and `elif` blocks could previously be deleted when applying a fix
for this rule. If an `else` or `elif` branch is detected the rule will
not trigger. So now the rule will only flag if it is safe.
## Summary
Resolves#20004
The implementation now supports guaranteed-mutable expressions in the
following cases:
- Tuple literals with mutable elements (supporting deep nesting)
- Generator expressions
- Named expressions (walrus operator) containing mutable components
Preserves original formatting for assignment value:
```python
# Test case
def f5(x=([1, ])):
print(x)
```
```python
# Fix before
def f5(x=(None)):
if x is None:
x = [1]
print(x)
```
```python
# Fix after
def f5(x=None):
if x is None:
x = ([1, ])
print(x)
```
The expansion of detected expressions and the new fixes gated behind
previews.
## Test Plan
- Added B006_9.py with a bunch of test cases
- Generated snapshots

Resolves https://github.com/astral-sh/ruff/issues/20512
This PR expands FA102’s preview coverage to flag every
PEP 585-compatible API that breaks without from `from __future__ import
annotations`, including `collections.abc`. The rule now treats asyncio
futures, pathlib-style queues, weakref containers, shelve proxies, and
the full `collections.abc` family as generics once preview mode is
enabled.
Stable behavior is unchanged; the broader matching runs behind
`is_future_required_preview_generics_enabled`, letting us vet the new
diagnostics before marking them as stable.
I've also added a snapshot test that covers all of the newly supported
types.
Check out
https://docs.python.org/3/library/stdtypes.html#standard-generic-classes
for a list of commonly used PEP 585-compatible APIs.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
First contribution so please let me know if I've made a mistake
anywhere. This was aimed to fix#19982, it adds the isolation level to
PYI021 to in the same style as the PIE790 rule.
fixes: #19982
## Test Plan
<!-- How was it tested? -->
I added a case to the PYI021.pyi file where the two rules are present as
there wasn't a case with them both interacting, using the minimal
reproducible example that @ntBre created on the issue (I think I got the
`# ERROR` markings wrong, so please let me know how to fix that if I
did).

## Summary
Fixes#12734
I have started with simply checking if any arguments that are providing
extra values to the log message are calls to `str` or `repr`, as
suggested in the linked issue. There was a concern that this could cause
false positives and the check should be more explicit. I am happy to
look into that if I have some further examples to work with.
If this is the accepted solution then there are more cases to add to the
test and it should possibly also do test for the same behavior via the
`extra` keyword.
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
I have added a new test case and python file to flake8_logging_format
with examples of this anti-pattern.

## Summary
Fixes#20440
Fix B004 to skip invalid hasattr/getattr calls
- Add argument validation for `hasattr` and `getattr`
- Skip B004 rule when function calls have invalid argument patterns
## Summary
Implements new rule `B912` that requires the `strict=` argument for
`map(...)` calls with two or more iterables on Python 3.14+, following
the same pattern as `B905` for `zip()`.
Closes#20057

## Summary
Resolves#20266
Definition of the frozen dataclass attribute can be instantiation of a
nested frozen dataclass as well as a non-nested one.
### Problem explanation
The `function_call_in_dataclass_default` function is invoked during the
"defined scope" stage, after all scopes have been processed. At this
point, the semantic references the top-level scope. When
`SemanticModel::lookup_attribute` executes, it searches for bindings in
the top-level module scope rather than the class scope, resulting in an
error.
To solve this issue, the lookup should be evaluated through the class
scope.

## Summary
Fixes#20204
Recognize t-strings, generators, and lambdas in RUF016
- Accept boolean literals as valid index and slice bounds.
- Add TString, Generator, and Lambda to `CheckableExprType`.
- Expand RUF016.py fixture and update snapshots accordingly.
Our token-based rules and `noqa` extraction used an `Indexer` that kept
track of f-string ranges but not t-strings. We've updated the `Indexer`
and downstream uses thereof to handle both f-strings and t-strings.
Most of the diff is renaming and adding tests.
Note that much of the "new" logic gets to be naive because the lexer has
already ensured that f and t-string "starts" are paired with their
respective "ends", even amidst nesting and so on.
Finally: one could imagine wanting to know if a given interpolated
string range corresponds to an f-string or a t-string, but I didn't find
a place where we actually needed this.
Closes#20310

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Fixes#20235
• Fix `RUF102` to properly handle rule redirects when validating noqa
codes
• Update `code_is_valid` to check redirect targets before determining
validity
• Add test case for rule redirects (TCH002 in this case)
## Test Plan
<!-- How was it tested? -->
I have added a test case for rule redirects to
`crates/ruff_linter/resources/test/fixtures/ruff/RUF102.py`.
## Summary
Resolves#19357
Skip UP008 diagnostic for `builtins.super(P, self)` calls when
`__class__` is not referenced locally, preventing incorrect fixes.
**Note:** I haven't found concrete information about which cases
`__class__` will be loaded into the scope. Let me know if anyone has
references, it would be useful to enhance the implementation. I did a
lot of tests to determine when `__class__` is loaded. Considered
sources:
1. [Python doc
super](https://docs.python.org/3/library/functions.html#super)
2. [Python doc classes](https://docs.python.org/3/tutorial/classes.html)
3. [pep-3135](https://peps.python.org/pep-3135/#specification)
As I understand it, Python will inject at runtime into local scope a
`__class__` variable if it detects references to `super` or `__class__`.
This allows calling `super()` and passing appropriate parameters.
However, the compiler doesn't do the same for `builtins.super`, so we
need to somehow introduce `__class__` into the local scope.
I figured out `__class__` will be in scope with valid value when two
conditions are met:
1. `super` or `__class__` names have been loaded within function scope
4. `__class__` is not overridden.
I think my solution isn't elegant, so I would be appreciate a detailed
review.
## Test Plan
Added 19 test cases, updated snapshots.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
### Why
Removal should be grouped into the same category. It doesn't matter
whether it's from a provider or not (and the only case we used to have
was not anyway).
`ProviderReplacement` is used to indicate that we have a replacement and
we might need to install an extra Python package to cater to it.
### What
Move `airflow.operators.postgres_operator.Mapping` from AIR302 to AIR301
and get rid of `ProviderReplace::None`
## Test Plan
<!-- How was it tested? -->
Update the test fixtures accordingly in the first commit and reorganize
them in the second commit
