The CircuitBreakerMiddleware was blocking all requests (503 circuit_open) because
every exception in get_db() — including 401 Unauthorized, 403 Forbidden, 404 Not Found —
was calling record_failure() on the DB circuit breaker. This caused the circuit to
trip after 5 non-DB errors (e.g. failed login attempts during security testing).
Fix: Only call record_failure() when _is_transient_db_error(exc) returns True,
filtering out HTTP exceptions that are not DB-related.
- app/core/resilience.py: CircuitBreaker (CLOSED/OPEN/HALF_OPEN), retry_db,
redis_call_with_fallback, InMemoryRateLimiter, CircuitBreakerMiddleware
- app/core/auth.py: get_session_data now falls back to PostgreSQL sessions
table when Redis is unavailable
- app/core/permissions.py: get_cached_permissions falls back to direct DB
resolution when Redis circuit is open
- app/core/rate_limit.py: check_rate_limit falls back to in-memory limiter
when Redis is down; reset_rate_limit clears both Redis and in-memory
- app/core/middleware.py: CSRF validation uses get_session_data (Redis+DB
fallback); sliding session TTL is best-effort during outage
- app/core/db/__init__.py: get_db() wraps session creation with retry_db
for transient connection errors; records circuit breaker success/failure
- app/deps.py: refresh_session_ttl wrapped in try/except for Redis outage
- app/main.py: CircuitBreakerMiddleware registered (returns 503 when DB
circuit is OPEN, skips health/metrics endpoints)
- app/config.py: Added resilience settings (thresholds, cooldown, retries)
- tests/test_resilience.py: 30 tests covering all patterns
30/30 resilience tests pass. No regressions in plugin lifecycle tests.
- main.py: registry.initialize(get_migration_engine()) instead of get_engine()
- main.py: plugin migrations run via get_migration_session_factory() not async_session()
- registry.py: upgrade_plugin, install_plugin, uninstall_plugin all use migration session for DDL
- db/__init__.py: get_migration_engine() raises RuntimeError if MIGRATION_DATABASE_URL missing (no fallback)
- Fixes fresh-install failure: crm_api has no DDL rights, plugin migrations need crm_migration
- config.py: add auth_database_url, worker_database_url, migration_database_url
- db/__init__.py: separate engines for auth/worker/migration + get_auth_db/get_worker_db
- auth.py: all auth endpoints use get_auth_db (crm_auth role)
- auth_service.py: remove login fallback, require active membership, check status
- auth_service.py: switch_tenant checks active membership status
- alembic/env.py: use migration_database_url for Alembic
- docker-compose.yml: add AUTH_DATABASE_URL, WORKER_DATABASE_URL
- .env.example: add all 4 DB URLs with separate roles
- migration 0085: transfer ownership to crm_migration, fix BYPASSRLS,
enable RLS+FORCE on all tenant tables, drop old policies, create new
fail-closed policies scoped to crm_api+crm_worker, revoke excessive grants,
grant minimal crm_auth access, drop crm_runtime, set default privileges
- tests/test_rls_coverage.py: automated RLS coverage check (13 tests)
- tests/test_cross_tenant_security_v2.py: RLS tests with unprivileged role
- Fix report_generator/jobs.py: use DmsContract instead of direct DMS import
- Remove app.tenant_id from set_tenant_context (only app.current_tenant_id)
- Create tests/test_cross_tenant_security_v2.py with real RLS tests using
unprivileged crm_api role (NOSUPERUSER, NOBYPASSRLS)
- Fix existing tests referencing app.tenant_id
- Git baseline tag v-phase0-baseline at 11d6faa
- Production DB backup at /tmp/crm_backup_20260731_015514.dump
