chore(ingestion): drop pylint, expand ruff (#27774)
* chore(ingestion): drop pylint, expand ruff to Stage 2c

Replace pylint with a coherent ruff-only stack (Stage 2c of the modernize
roadmap). Pylint is dropped from dev deps and CI workflows; ruff selected
ruleset expanded to ~22 families covering style, bug catchers, hygiene,
and the pylint port (PLE/PLC/PLW/PLR with the noisy "too-many-X"
complexity caps + magic-value disabled).

What's selected (with rationale in pyproject.toml):
  E, W, F, I, N         — style + correctness baseline + naming
  UP                    — pyupgrade (py>=3.10 modernizations)
  B, C4, C90, RET, SIM, TRY  — bug catchers
  PIE, ICN, T20, TC, TID, PTH, PERF  — hygiene
  PLE, PLC, PLW, PLR    — pylint port (PLR complexity caps ignored)
  RUF                   — ruff-native (incl. RUF100 unused-noqa)

What's removed:
  - .pylintrc (root) — duplicate of the ingestion pylint config
  - [tool.pylint.*] block in ingestion/pyproject.toml (~140 lines)
  - ingestion/plugins/{print_checker,import_checker}.py + tests + README
    (replaced by built-in T20 + TID251 banned-api respectively)
  - pylint dep from ingestion/setup.py and openmetadata-airflow-apis/pyproject.toml
  - `make lint` Makefile target + the pylint invocation in py_format_check
  - dead pylint TODO comment + ignored test entry in noxfile.py

Cwd-stable config: ruff is invoked both from the repo root (pre-commit,
CI) and from ingestion/ (`make py_format_check`). The `src`,
`extend-exclude`, and per-file-ignores entries are listed twice — once
relative to ingestion/ and once with the `ingestion/` prefix — so
first-party isort detection and exclusions match in both invocations.

Grandfathering: ran `ruff check --add-noqa` once + format-stable
iteration. ~12,130 noqa directives across ~1,400 files. Cleanup is
deferred to follow-up PRs that drop noqas one rule at a time.

Documentation sweep: replaced `make lint` references in CLAUDE.md,
AGENTS.md, DEVELOPER.md, copilot-instructions, and 6 SKILL files with
the apply+verify shape `make py_format && make py_format_check`.
`make py_format` is NOT a strict superset of pylint — it only applies
auto-fixable violations; `make py_format_check` catches the rest.

Basedpyright baseline regenerated: ruff format reflowed multi-line
signatures in ~70 files, shifting type-error column positions. The
basedpyright baseline matches by (file path, error code, range), so
column shifts caused 19 entries to mis-align. Net diff is small
(154 lines in/out of the 13MB baseline.json) — purely positional.

Verified locally:
  - make py_format_check         → All checks passed
  - nox --no-venv -s static-checks → 0 errors, 0 warnings, 0 notes

* chore(ingestion): finish ruff swap — nox lint session + skill docs

Three remaining stale-tooling references after Stage 2c:

  - `ingestion/noxfile.py` `lint` session was still calling `black --check`,
    `isort --check-only`, `pycln --diff`. Those tools aren't installed
    anywhere (we dropped them from dev deps). Replace with the ruff
    equivalents that mirror `make py_format_check`.
  - `skills/standards/code_style.md`: stack listed as `black + isort +
    pycln`; line length claimed 88 (black default). Both wrong: stack is
    ruff, line length is 120.
  - `skills/connector-building/SKILL.md`: `make py_format` comment said
    `# black + isort + pycln`. Same swap.

* chore(ingestion): keep main's baseline + globally ignore TRY400

Per gitar-bot's review on PR #27774:

1. Main's PR #27728 promoted ~60 `logger.warning()` → `logger.error()`
   inside `except` blocks. Those changes landed on main with their own
   baseline updates. Our PR doesn't promote anything — the merge from
   origin/main brought those `error` calls along with their baseline
   entries.

   The bot interpreted the `# noqa: TRY400` we added next to those lines
   as us silencing the rule case-by-case. Cleaner: globally ignore
   TRY400 in pyproject.toml, with a comment explaining why the codebase's
   `logger.error(...)` + separate `logger.debug(traceback.format_exc())`
   pattern is intentional. Strip ~430 per-line `# noqa: TRY400` markers
   from source.

2. Document that `S101` in `per-file-ignores` is a forward-looking
   entry — flake8-bandit (`S`) is not yet selected, so the rule is
   no-op today; the entry stays so when `S` lands later, tests don't
   immediately error.

Reverts the platform pin and Linux Docker–generated baseline. Keep
main's baseline intact and let CI surface the exact column-shifted
entries; the team will decide whether to fix in-place (revert format
on affected files) or add per-line `# pyright: ignore` markers.

* chore(ingestion): regen baseline for new connector type debt

Main's baseline was stale relative to recently-added connectors
(McpConnection, CustomDriveConnection) that lack common attributes
like `hostPort`, `database`, `catalog` etc. — all sites that access
those attributes via the union-typed `serviceConnection.root.config`
fire `reportAttributeAccessIssue` errors that aren't baselined.

71 errors + 58 warnings absorbed. Local macOS regen; pushing to see
CI's drift count. Per the basedpyright-baseline-and-ci PR experience,
macOS↔Linux column drift on this size of regen has historically been
1-7 residuals.

python-reviewer Review Python code changes against OpenMetadata ingestion patterns — connector architecture, Pydantic 2.x models, pytest conventions, and schema-first design

Python Code Reviewer Agent

You are a senior Python reviewer specializing in the OpenMetadata ingestion framework.

Context

OpenMetadata ingestion uses:

  • Python 3.10-3.11 with Pydantic 2.x
  • 75+ connectors following a plugin architecture
  • Schema-first design — JSON schemas generate Pydantic models via make generate
  • pytest for testing (not unittest)
  • ruff for formatting + linting (make py_format to apply, make py_format_check to verify)
  • basedpyright for type checking (make static-checks)

Review Task

Given a set of changed files, review against these criteria:

1. Code Style

  • Pydantic 2.x patterns (not v1 compatibility layer)
  • Type hints on all public functions
  • ingestion_logger() for logging (not raw logging.getLogger)
  • Copyright header present on new files
  • No connector-specific logic in shared files like builders.py

2. Connector Architecture

  • Follows the established source class hierarchy (Source -> TopologyMixin)
  • Uses ServiceSpec or DefaultDatabaseSpec for topology definition
  • Connection logic in connection.py, metadata extraction in metadata.py
  • Proper yield patterns for streaming entities (memory efficiency)
  • Error handling with Either pattern for non-fatal errors

3. Testing (90% coverage target)

  • pytest style — plain assert, no unittest.TestCase inheritance
  • pytest fixtures for setup, not setUp/tearDown methods
  • Tests verify real behavior — don't mock everything
  • assert x == y not self.assertEqual(x, y)
  • 90% line coverage on changed modules (measured by pytest --cov)

4. Performance & Memory

  • Large result sets use generators/iterators, not lists
  • Pagination implemented for API calls
  • No unbounded data accumulation in memory

5. Security

  • No hardcoded credentials or API keys
  • Secrets handled through OpenMetadata's secret manager
  • No eval() or exec() on external input
