kevinveenbirkenbachandClaude Opus 4.7 26ef3ff504 chore(ruff): enable strict ruleset (E/F/I/B/UP, py311) — 2819 → 0
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  ``from typing import …`` redirected where superseded by builtins.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.

"""In-process caches for runtime data (applications, users, domains).
Domain modules:
- ``utils.cache.base`` — cross-cutting helpers (constants,
deep-merge, signatures, render machinery).
- ``utils.cache.applications`` — variants + ``get_merged_applications``
(ansible-free at import time, runner-host friendly).
- ``utils.cache.users`` — ``get_user_defaults``, ``get_merged_users``.
- ``utils.cache.domains`` — ``get_merged_domains``.
- ``utils.cache.yaml`` — process-wide ``load_yaml`` /
``load_yaml_any`` parser cache shared by everything that reads YAML
off-disk.
- ``utils.cache.files`` — process-wide project-tree walk +
file-content cache (``read_text``, ``iter_project_files``,
``iter_non_ignored_files``).
- ``utils.cache.gitignore`` — cached ``.gitignore`` pattern loader
+ path matcher used by lint/integration tests that need a
"files git would track" view without spawning git.
Use the domain module directly. The package-level
``_reset_cache_for_tests`` clears every domain's caches plus the shared
fingerprint memo in one call — preferred over hand-rolling N
``_reset()`` calls per test fixture.
