3529 invalid comments in 528 files, grandfathered in while the linter
only saw the working-tree diff. Removal ran through the linter's own
collectors, so detection and deletion cannot drift: a comment whose
opener line is blank before it and whose closer line is blank after it
loses all its lines, anything else loses only the comment region, and a
line left holding a bare delimiter goes with it.
Five files keep their comments behind a nocheck marker instead. Four are
upstream configs whose inline docs are upstream's own (mautrix, systemd
journald, nextcloud-oidc-login, MediaWiki). In littlejs the
commented-out entries ARE the deactivation mechanism for an example
tile, so deleting them would delete configuration.

Removed leading `# filter_plugins/...py` / `# lookup_plugins/...py`
comments that referenced the old plugin paths. The plugins now live
under plugins/filter and plugins/lookup, so these headers are both
inaccurate and redundant.

Extends ``[tool.ruff.lint].select`` with six additional rule families:
``RUF`` (ruff-specific), ``SIM`` (flake8-simplify), ``C4``
(flake8-comprehensions), ``PERF`` (perflint), ``RET`` (flake8-return),
``PIE`` (flake8-pie). Adds ``RUF001/002/003`` to ``ignore`` because
those exist for homoglyph-attack detection, not English typography —
the project uses em/en-dashes and ``ℹ`` as a UI-hint glyph in CLI help
output deliberately.
Auto-fixed (~225, mechanical & behavior-preserving)
====================================================
- RUF005: ``a + [b]`` → ``[*a, b]``
- C408: ``dict(k=v)`` → ``{"k": v}``
- C420: ``dict.fromkeys(seq)`` shape simplifications
- SIM103/SIM110/SIM118: truthy-return / dict-key / dict-method
idiom simplifications
- RET504/RET505: drop unneeded final assigns / ``else`` after
``return``
- PIE810: combine ``str.startswith(a) or .startswith(b)``
into one call with a tuple
- RUF010: ``f"{str(x)}"`` → ``f"{x\!s}"``
- RUF100: removed unused ``# noqa`` directives that
became stale (mostly old ``# noqa: E402``
markers that ruff's smart E402 implementation
no longer flags after ``sys.path`` shims)
- RUF015 / RUF013 / RUF022 / RUF046 / RUF059: misc small wins
- I001: re-sorted import blocks where the new
imports above shifted them
Hand-fixed (~140, scripted where mechanical)
============================================
PERF401 (42): scripted AST rewrite of
``for x in iter: target.append(expr)`` (with optional ``if`` guard)
→ ``target.extend(expr for x in iter [if cond])``.
``list.extend(genexp)`` consumes the generator immediately, so the
rewrite is semantically equivalent to the original eager loop.
SIM117 (41): scripted AST combiner for nested ``with`` blocks where
the inner is the only statement of the outer (38 sites). The remaining
3 multi-line ``patch.object(...)`` chains were combined by hand using
the parenthesised ``with (\\n A,\\n B,\\n):`` form.
SIM102 (14): scripted AST combiner for nested ``if`` (10 sites). The
remaining 4 carry an inline ``# noqa: SIM102`` with rationale —
combining would either change semantics (the outer body has siblings
beyond the inner ``if``, e.g. ``cli/encrypt/inventory/__main__.py``
where ``encrypted_value = …`` runs regardless of ``ask_confirmation``)
or hurt readability (long literal whitelists).
RUF012 (9): annotated mutable class attributes with ``ClassVar[…]``
and added ``from typing import ClassVar``.
SIM105 (6): ``try/except: pass`` → ``with contextlib.suppress(…):``
with the necessary ``import contextlib`` added. Verified on
``utils/templating.py`` (3 occurrences in a ``finally`` block) —
cleanup behaviour is identical.
SIM115 (4): wrapped ``tempfile.NamedTemporaryFile(..., delete=False)``
call patterns in a ``with`` block; ``delete=False`` keeps the file
on disk after the block, so callers' ``return f.name`` still works.
PERF402, PERF403, B007, SIM108, SIM103: 5 misc fixes (loop→list-copy,
loop→dict-comprehension, unused-loop-var rename, ternary, return
expression).
Verification
============
- ``ruff check .`` → All checks passed
- ``ruff format --check .`` → 894 files already formatted
- 1621 unit tests → all pass
- Integration suite: 44 baseline failures, 1 skipped (unchanged)
- Sample-audited PERF401 rewrites in ``resolver.py``, ``inventory.py``,
``cache/files.py``, ``ressources/__main__.py``; SIM117 in
``test_main.py``; SIM105 in ``utils/templating.py``; SIM102 noqa
rationales in ``cli/encrypt/inventory/__main__.py``.
182 files changed, +993 / −960. With this and the prior strict-rule
commit the branch satisfies 11 ruff rule families end-to-end.

Adds ``[tool.ruff.lint]`` with ``select = ["E", "F", "I", "B", "UP"]``
and ``target-version = "py311"``. ``E501`` is ignored because
``ruff format`` already reflows what it can; the remaining long lines
are unsplittable string literals / URLs.
Auto-fixed (2753 issues, behavior-preserving):
- UP006/UP035: ``List[X]`` → ``list[X]``, ``Dict[X]`` → ``dict[X]``,
``from typing import …`` redirected where superseded by builtins.
- UP045: ``Optional[X]`` → ``X | None``.
- UP010/UP009/UP015: dropped Python-2-era pragmas (``from __future__
import absolute_import, division, print_function``,
``# -*- coding: utf-8 -*-``), redundant ``open(..., "r")`` mode.
- UP004: dropped implicit ``class X(object):``.
- UP022/UP008/UP032: stdlib idiom modernization (``capture_output``,
super-call simplification, etc.).
- B905: ``zip(...)`` → ``zip(..., strict=False)`` (preserves prior
behavior; switching to ``strict=True`` is a separate semantic
choice not made here).
- I001: import-block ordering.
Hand-fixed (66 issues):
- B904 × 54: appended ``from <bound>`` (when the enclosing ``except``
binds a name) or ``from None`` (when it doesn't) so chained
exceptions stay distinguishable from errors-during-exception-
handling. Applied via a small AST-aware script that walked back to
the enclosing ``except`` clause and matched the binding.
- B017 × 4: narrowed broad ``assertRaises(Exception)`` to the actual
``AnsibleError`` / ``AnsibleFilterError`` raised by the code under
test.
- B023 × 2: bound captured loop variables via default args
(``def _record(name, *, _path_real=path_real, ...)``) so each
closure gets its own snapshot.
- B007 × 2: unused loop control variables renamed to ``_`` /
rewritten to ``.values()``.
- UP007 × 2: ``Union[X, Y]`` → ``X | Y`` (plus dropping the now-unused
``from typing import Union``).
- B018 × 1: Odoo addon manifests are bare dict expressions at module
level by design — suppressed with an inline ``# noqa: B018`` and
rationale comment.
- UP031 × 1: printf-style format → f-string.
The 65 ``# noqa: …`` markers introduced by the auto-fixer all carry
real ruff codes (``B018``, ``E402``, ``F401``, etc.), so
``test_noqa_only_ruff_codes`` stays green.
Verification
============
- ``ruff check .`` → All checks passed
- ``ruff format --check .`` → 894 files already formatted
- ``tests.lint.repository.{test_project_root_import,
test_no_direct_yaml_calls, test_noqa_only_ruff_codes}`` and
``tests.unit.utils.annotations.test_suppress`` → 20 tests OK
- 1621 unit tests → all pass
- Integration suite: 44 failures (pre-existing baseline, none from
this change), 1 skipped.
Going forward, the new rules block regressions on E (style), F
(pyflakes), I (import order), B (likely-bug patterns), and UP
(modernization to py311) for any new code.
