[flake8-gettext] Swap format- and printf-in-get-text-func-call examples (INT002, INT003) (#16769)

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)

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.tomlor 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 (PGH004): Also detect blanked file-level noqa comments (and not just line level comments).

Changes to how the Python version is inferred when a target-version is not specified (#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)

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)

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 for the full specification.
Avoid unnecessary parentheses around with statements with a single context manager and a trailing comment (#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)

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 rules have been deprecated:

non-pep604-isinstance (UP038)
suspicious-xmle-tree-usage (S320)

Remapped rules

The following rules have been remapped to new rule codes:

[unsafe-markup-use]: RUF035 to S704

Stabilization

The following rules have been stabilized and are no longer in preview:

batched-without-explicit-strict (B911)
unnecessary-dict-comprehension-for-iterable (C420)
datetime-min-max (DTZ901)
fast-api-unused-path-parameter (FAST003)
root-logger-call (LOG015)
len-test (PLC1802)
shallow-copy-environ (PLW1507)
os-listdir (PTH208)
invalid-pathlib-with-suffix (PTH210)
invalid-assert-message-literal-argument (RUF040)
unnecessary-nested-literal (RUF041)
unnecessary-cast-to-int (RUF046)
map-int-version-parsing (RUF048)
if-key-in-dict-del (RUF051)
unsafe-markup-use (S704). This rule has also been renamed from RUF035.
split-static-string (SIM905)
runtime-cast-value (TC006)
unquoted-type-alias (TC007)
non-pep646-unpack (UP044)

The following behaviors have been stabilized:

bad-staticmethod-argument (PLW0211) invalid-first-argument-name-for-class-method (N804): __new__ methods are now no longer flagged by invalid-first-argument-name-for-class-method (N804) but instead by bad-staticmethod-argument (PLW0211)
bad-str-strip-call (PLE1310): The rule now applies to objects which are known to have type str or bytes.
custom-type-var-for-self (PYI019): More accurate detection of custom TypeVars replaceable by Self. The range of the diagnostic is now the full function header rather than just the return annotation.
invalid-argument-name (N803): Ignore argument names of functions decorated with typing.override
invalid-envvar-default (PLW1508): Detect default value arguments to os.environ.get with invalid type.
pytest-raises-with-multiple-statements (PT012) pytest-warns-with-multiple-statements (PT031): Allow for statements with an empty body in pytest.raises and pytest.warns with statements.
redundant-open-modes (UP015): The diagnostic range is now the range of the redundant mode argument where it previously was the range of the entire open call. You may have to replace your noqa comments when suppressing UP015.
stdlib-module-shadowing (A005): Changes the default value of lint.flake8-builtins.strict-checking from true to false.
type-none-comparison (FURB169): Now also recognizes type(expr) is type(None) comparisons where expr isn't a name expression.

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). ##### Preview features - \[syntax-errors] Tuple unpacking in `for` statement iterator clause before Python 3.9 ([#16558](https://github.com/astral-sh/ruff/pull/16558)) ### [`v0.10.0`](https://github.com/astral-sh/ruff/blob/HEAD/CHANGELOG.md#0100) [Compare Source](https://github.com/astral-sh/ruff/compare/0.9.10...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 rules have been deprecated: - [`non-pep604-isinstance`](https://docs.astral.sh/ruff/rules/non-pep604-isinstance/) (`UP038`) - [`suspicious-xmle-tree-usage`](https://docs.astral.sh/ruff/rules/suspicious-xmle-tree-usage/) (`S320`) ##### Remapped rules The following rules have been remapped to new rule codes: - \[`unsafe-markup-use`]: `RUF035` to `S704` ##### Stabilization The following rules have been stabilized and are no longer in preview: - [`batched-without-explicit-strict`](https://docs.astral.sh/ruff/rules/batched-without-explicit-strict) (`B911`) - [`unnecessary-dict-comprehension-for-iterable`](https://docs.astral.sh/ruff/rules/unnecessary-dict-comprehension-for-iterable) (`C420`) - [`datetime-min-max`](https://docs.astral.sh/ruff/rules/datetime-min-max) (`DTZ901`) - [`fast-api-unused-path-parameter`](https://docs.astral.sh/ruff/rules/fast-api-unused-path-parameter) (`FAST003`) - [`root-logger-call`](https://docs.astral.sh/ruff/rules/root-logger-call) (`LOG015`) - [`len-test`](https://docs.astral.sh/ruff/rules/len-test) (`PLC1802`) - [`shallow-copy-environ`](https://docs.astral.sh/ruff/rules/shallow-copy-environ) (`PLW1507`) - [`os-listdir`](https://docs.astral.sh/ruff/rules/os-listdir) (`PTH208`) - [`invalid-pathlib-with-suffix`](https://docs.astral.sh/ruff/rules/invalid-pathlib-with-suffix) (`PTH210`) - [`invalid-assert-message-literal-argument`](https://docs.astral.sh/ruff/rules/invalid-assert-message-literal-argument) (`RUF040`) - [`unnecessary-nested-literal`](https://docs.astral.sh/ruff/rules/unnecessary-nested-literal) (`RUF041`) - [`unnecessary-cast-to-int`](https://docs.astral.sh/ruff/rules/unnecessary-cast-to-int) (`RUF046`) - [`map-int-version-parsing`](https://docs.astral.sh/ruff/rules/map-int-version-parsing) (`RUF048`) - [`if-key-in-dict-del`](https://docs.astral.sh/ruff/rules/if-key-in-dict-del) (`RUF051`) - [`unsafe-markup-use`](https://docs.astral.sh/ruff/rules/unsafe-markup-use) (`S704`).
