Louis King	b9083d6bb7	fix(cache): preserve repeated query params in cache key ... The API response cache key was built from request.query_params.items(), which in Starlette keeps only the last value of a repeated key. Repeated params like observed_by (?observed_by=A&observed_by=B) therefore collapsed to observed_by=B in the key, colliding with any other filter set sharing the same last value. The first response cached under that key was then served for the whole TTL, making observer-filtered Messages/Adverts return stale, wrong results (e.g. an A-only message vanishing when B was also enabled). Use multi_items() so all repeated values are included, sorted by the full (key, value) tuple so order-independent filter sets map to one key. Add regression tests covering preservation, order-independence, and the {A,B} vs {B} collision case. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-14 23:25:15 +01:00
Louis King	fb435a53c4	test: add coverage for Redis caching layer ... Add 29 new tests covering previously uncovered code paths: - redis.py: delete(), close(), string value decoding - cache.py: serialization branches (pydantic, dict, list), set error fallback - app.py: lifespan Redis init (enabled/disabled), cache close on shutdown - app.py: X-Cache middleware (HIT/MISS/no-status) - app.py: /health/ready Redis status (connected/unreachable/omitted) - cli.py: Redis banner output, create_app param passthrough - Route key builders: dashboard/stats, dashboard/message-activity, channels, messages	2026-06-09 23:30:29 +01:00
Louis King	385d1ab141	feat: add optional Redis caching layer for API endpoints ... Add Redis-backed response caching for read-heavy API endpoints (nodes, advertisements, messages, channels, dashboard, profiles) with configurable TTL, key prefix isolation, and graceful fallback when Redis is unavailable. New files: - common/redis.py: CacheBackend, NullCache, RedisCacheBackend - api/cache.py: @cached decorator, sorted_query_string helper - tests/test_api/test_cache.py: 23 unit tests Changes: - pyproject.toml: add redis[hiredis] dependency - common/config.py: 8 Redis settings on APISettings - api/cli.py: Redis Click options + startup banner - api/app.py: Redis lifespan init/cleanup, X-Cache middleware, health check - 6 route files: apply @cached decorator to list endpoints - docker-compose.yml: Redis service (cache profile), env vars - docker-compose.dev.yml: Redis port exposure - .env.example, README.md, AGENTS.md, docs/upgrading.md: documentation Redis is disabled by default (REDIS_ENABLED=false). Enable with --profile cache and REDIS_ENABLED=true.	2026-06-09 23:08:49 +01:00
