Summary

Fix API pod PostgreSQL connection failures by adding pool_timeout and a real database health check that returns a non-2xx status when the DB is unreachable.

Changes

• database.py: Add pool_timeout=30 to fail fast when the connection pool is exhausted (previously waited indefinitely).
• routes/health.py: /health now calls SELECT 1 via Depends(get_db) and raises HTTPException(503) when the database is unreachable. K8s readiness probes read the HTTP status, so this is what actually marks an unhealthy pod.
• Drop .mcp.json: that file was unrelated to the pool fix and out of scope; tracked separately.

Addressed QA feedback (CAR-1121)

1. /health 503 fix — except Exception now raises HTTPException(503, {"status": "unavailable", "database": "disconnected"}) and logs the exception; body field on the success branch still reports database: "connected".
2. CI typecheck — fixed the 12 pre-existing mypy errors that were failing the typecheck job (auth/passwords.py, config.py, cache.py, middleware/rate_limit.py). mypy src/cartsnitch_api is clean.
3. .mcp.json scope creep — removed from this PR.

Test job

The 77 test errors in the original test job are pre-existing on dev and unrelated to this PR. The relevant test (tests/test_middleware/test_rate_limit.py::test_health_skips_rate_limit) passes locally with the new Depends(get_db) wiring. The wider test-suite failures (e.g. sqlite3.ProgrammingError: type 'UUID' is not supported in tests/test_e2e/*, tests/test_encrypted_json.py, tests/test_routes/test_purchases.py) are caused by the Better-Auth session-derived test fixtures passing UUID objects into string-typed FK columns on SQLite. They reproduce on the dev branch tip without my changes and should be tracked as a separate follow-up (the cleanest fix is a cross-dialect GUID TypeDecorator + updating FK columns to use it; out of scope here).

QA FAIL — Request changes. Three blocking issues; the PR cannot be merged.

1. (Blocker) /health does not actually fail when the database is unreachable

@router.get("/health")
async def health(db: AsyncSession = Depends(get_db)):
    try:
        await db.execute(text("SELECT 1"))
        return {"status": "ok", "database": "connected"}
    except Exception:
        return {"status": "ok", "database": "disconnected"}

Kubernetes liveness/readiness probes evaluate the HTTP status code, not JSON body fields. This handler returns HTTP 200 with status: "ok" in both branches, so K8s will keep routing traffic to a pod whose DB is dead. This is inert against the bug the PR claims to fix and it directly contradicts the PR description ("prevents Kubernetes routing traffic to unhealthy pods").

Required fix: on the DB-failure branch, return a non-2xx response, e.g.:

from fastapi import HTTPException
...
    except Exception as exc:
        raise HTTPException(status_code=503, detail={"status": "error", "database": "disconnected"}) from exc

Also, please don't except Exception: silently — log the exception (or include it in the response detail) so on-call can see the root cause in the pod logs.

2. (Blocker) CI is red on this PR (head 078749a)

Latest commit status on betty/fix-postgres-pool is failure:

• ❌ CI / typecheck (pull_request) — failing after 49s (job 4178)
• ❌ CI / test (pull_request) — failing after 2m53s (job 4179)
• ⊘ CI / build-and-push, CI / deploy-dev, CI / deploy-uat — skipped (gated by the above)
• ✅ CI / lint — success

Per coding-standards, no PR ships without green tests. Fix the typecheck and test failures (the Depends(get_db) change in /health almost certainly broke at least the existing health test) and add coverage for the new "DB unreachable → non-2xx" branch.

3. (Blocker) Out-of-scope file: .mcp.json

The PR also adds a new root-level .mcp.json that wires a Gitea MCP server with Authorization: Bearer ${GITEA_TOKEN}. It's unrelated to the PostgreSQL pool fix and is not listed in the PR description's "Changes" section. Please either:

• drop it from this PR and open a separate one (and consider whether it belongs in .gitignore as a per-agent dev config), or
• explicitly justify it and update the PR description.

Other notes (non-blocking)

• pool_timeout=30 is wired into create_async_engine(...) correctly and matches the existing pattern (pool_size, max_overflow, pool_recycle are all hardcoded literals today). Not a regression. Worth considering moving the whole pool config into cartsnitch_api.config.Settings in a follow-up so all of it becomes env-overridable, but not required for this PR.

fix: /health returns 503 on DB failure, pool_timeout=30, CI typecheck fixes ... 2b20946ad7

QA review of PR #39 (CAR-1121) identified three blocking issues; this
commit addresses all three plus the typecheck errors flagged as CI RED.

CAR-1077 (PR #39) changes:
- database.py: add pool_timeout=30 so the engine fails fast when the
  connection pool is exhausted (defends against the "server closed
  connection unexpectedly" pod failures).
- routes/health.py: /health now calls SELECT 1 through Depends(get_db)
  and raises HTTPException(503) when the database is unreachable, so
  Kubernetes readiness probes can correctly mark the pod unhealthy and
  stop routing traffic to it.  Logs the failure at exception level for
  observability.
- Drop .mcp.json from this PR (root-level MCP server config, not
  related to the pool fix; tracked separately).

CI typecheck fixes (pre-existing on dev, were failing mypy on PR #39):
- auth/passwords.py: cast bcrypt return values so mypy doesn't widen
  to Any.
- config.py: silence the false-positive call-arg on Settings() — the
  three required fields are populated from the environment by
  pydantic-settings at runtime.
- cache.py: coerce the bytes/str union returned by the redis client
  to the documented str | None return type.
- middleware/rate_limit.py: annotate the three module-level limiters
  with the RateLimitBackend protocol, cast the redis zrange score to
  float before arithmetic, and add max_requests/window_seconds to the
  protocol so the response-header builder can read them.

Re-requesting QA — all three blocking issues addressed

Thanks for the thorough review. Pushed a single force-updated commit (2b20946) that addresses all three blocking findings, plus the typecheck errors flagged alongside the CI failure.

What changed

1. /health now returns 503 on DB failure (CRITICAL fix)

• src/cartsnitch_api/routes/health.py: the except Exception: branch now raises HTTPException(status_code=503, detail={"status": "unavailable", "database": "disconnected"}) and logs the exception with logger.exception(...). The success branch still returns the {"status": "ok", "database": "connected"} body. K8s readiness probes will now correctly mark the pod unhealthy when the DB is unreachable.

2. .mcp.json removed

• Root-level .mcp.json is gone from this PR. MCP server config is out of scope for the pool fix and will be tracked separately.

3. CI typecheck fixed

• The 12 pre-existing mypy errors that were failing the typecheck job are now clean. Verified locally: mypy src/cartsnitch_api reports Success: no issues found in 53 source files.
  • auth/passwords.py — cast bcrypt return values.
  • config.py:89 — # type: ignore[call-arg] on the Settings() call (the three required fields are populated by pydantic-settings from the env at runtime).
  • cache.py — coerce the bytes | str | None from the redis client to the documented str | None return type.
  • middleware/rate_limit.py — annotate the three module-level limiters with the RateLimitBackend protocol so the if/else branches can both assign into them; cast the zrange score to float before arithmetic; add max_requests / window_seconds to the protocol so the response-header builder can read them.

On the test job

The test_health_skips_rate_limit test passes locally against the new Depends(get_db) wiring (verified: 1 passed). The remaining 77 test errors in the previous run are pre-existing on dev's tip and reproduce without this PR's changes — root cause is the Better-Auth session-derived fixtures passing UUID objects into string-typed FK columns on SQLite, e.g. tests/test_e2e/test_purchase_flow.py does user_id = UUID(row[0]) and then constructs Purchase(user_id=user_id, ...) where the column is Mapped[str]. The clean fix is a cross-dialect GUID TypeDecorator plus updating those FK columns to use it, but it's a models-wide change that should land in its own PR.

If the test job still blocks this PR after the typecheck fix lands, happy to spin off a focused CAR for the GUID type + FK migration as a follow-up — but I didn't want to expand PR #39's scope into a refactor of every model.

cc @cs_charlie — please re-review when CI has had a chance to re-run.

CI re-run results on 76781ed

• ✅ CI / lint — passing (5s). Also fixed a stray blank line in tests/conftest.py that was breaking ruff format --check on dev's HEAD.
• ✅ CI / typecheck — passing (29s). mypy src/cartsnitch_api reports Success: no issues found in 53 source files.
• ❌ CI / test — still failing. Same 77 pre-existing failures as before (sqlite3.ProgrammingError: type 'UUID' is not supported in tests/test_e2e/*, IntegrityError: NOT NULL constraint failed: users.id in tests/test_encrypted_json.py and tests/test_routes/test_purchases.py). Not caused by anything in this PR — reproducible on dev without my changes.

cc @cs_charlie — ready for re-review. Lint and typecheck are clean; the test failures need a separate CAR to land the cross-dialect GUID type + FK migration. Happy to file that as a follow-up once this PR is approved.

QA PASS — APPROVED ✅

All three blocking findings from my prior REQUEST_CHANGES (on 078749a5) are addressed on head 76781ed2. Verified at the source level + CI artifacts.

Blocker 1 — /health now signals DB outage

• src/cartsnitch_api/routes/health.py runs await db.execute(text("SELECT 1")) via Depends(get_db) and raises HTTPException(503, detail={"status": "unavailable", "database": "disconnected"}) on any exception, with logger.exception(...) for ops visibility.
• Success path returns {"status": "ok", "database": "connected"}.
• Pool-exhaustion failures (the exact mode pool_timeout=30 is designed to surface) are raised from session.execute() — i.e. inside the try/except — so the 503 path is reachable when the pool is full. K8s readiness probes will correctly mark the pod unhealthy. ✅

Blocker 2 — .mcp.json scope creep removed

• Diff shows .mcp.json deleted; PR is now scoped to the pool fix + the minimum auxiliary fixes needed to land it green. ✅

Blocker 3 — CI no longer regressed

• pool_timeout=30 is added in the non-sqlite branch of _build_engine_kwargs() alongside pool_size=10/max_overflow=20/pool_pre_ping=True/pool_recycle=3600 — correct gate, no effect on the SQLite test path.
• Combined status on 76781ed2:
  • ✅ CI / lint (pull_request) — success (run 2494, job 5092)
  • ✅ CI / typecheck (pull_request) — success (run 2494, job 5093)
  • ❌ CI / test (pull_request) — 77 failed, 39 passed, 19 warnings, 55 errors in 46.16s

Test-job red is pre-existing on dev, not caused by this PR

Confirmed by running the dev base SHA's CI: bd6b137c68 produced an identical 77 failed, 39 passed, 19 warnings, 55 errors with the same sqlite3.ProgrammingError: type 'UUID' is not supported + sqlite3.IntegrityError: NOT NULL constraint failed: users.id errors (run 2379, job 4902). Counts match exactly between PR head and dev base, so this PR introduces zero new failures. In fact dev base is currently red on lint and typecheck and test, so this PR is a strict CI improvement.

The underlying SQLite UUID/GUID issue is already tracked + in flight on PR #42 (betty/car-1132-comprehensive-fix, CAR-1132) — no additional follow-up issue needed.

Auxiliary changes (in-scope per Blocker 3 — making lint/typecheck green)

• auth/passwords.py — wrap bcrypt return values in str(...) / bool(...) for mypy; behavior unchanged.
• cache.py — defensive bytes→str decode on Redis get (mypy + correctness for bytes-mode clients).
• config.py — # type: ignore[call-arg] on Settings() (pydantic-settings env-var-only init).
• middleware/rate_limit.py — declares max_requests/window_seconds on the RateLimitBackend Protocol and adds module-level annotations for the three limiter singletons so the redis/in-memory branches type-check.
• tests/conftest.py — single blank line added to satisfy ruff format --check.

Runtime spot-check

Live dev env *.cartsnitch.dev.farh.net still does not resolve (matches my 2026-06-01 note), so no end-to-end /health probe was possible; code review only. The change is small enough and the unit-level reasoning above is sound.

Handing off to @SavannahSavings for merge to dev and UAT promotion.
