From 3ca5cbf51fc4cccafc83202cf2f45092fbfc600d Mon Sep 17 00:00:00 2001 From: Clow Date: Mon, 23 Mar 2026 13:34:49 +0000 Subject: [PATCH 01/18] feat: add Solana RPC and GitHub API checks to health endpoint Closes #490 Extends the /health endpoint with two new external service checks: ## Solana RPC Check - POST getSlot to configured SOLANA_RPC_URL (defaults to mainnet-beta) - Returns current slot number on success - 200ms strict timeout to prevent health endpoint blocking - Reports: healthy / degraded (timeout, bad response) / unavailable ## GitHub API Check - GET /rate_limit with optional GITHUB_TOKEN authentication - Reports remaining rate limit calls and reset time - Degrades when remaining calls < 10% of limit - 200ms strict timeout ## Status Vocabulary (unified) - `healthy`: service fully operational - `degraded`: reachable but impaired (slow, rate-limited, timeout) - `unavailable`: cannot be reached ## Overall Status Logic - `unavailable` if any core service (DB/Redis) is unavailable - `degraded` if any service is degraded or external unavailable - `healthy` only when all four services healthy ## Response Format All services now return `latency_ms` on success for monitoring. ## Tests 26 tests covering: - Individual service checks (DB, Redis, Solana, GitHub) - All error scenarios (timeout, connection error, bad response) - Overall status logic (6 combinations) - Full endpoint integration tests (4 scenarios) - Response schema validation Wallet: HZV6YPdTeJPjPujWjzsFLLKja91K2Ze78XeY8MeFhfK8 --- backend/app/api/health.py | 193 ++++++++++++++---

+0000 Subject: [PATCH 02/18] fix: address CodeRabbit review feedback on health check endpoint - Remove unused httpx imports from test file (fixes ruff lint F401) - Fix GitHub rate limit threshold: use pure 10% of limit instead of max(limit*0.1, 100) which incorrectly penalises low-limit tokens - Catch JSON parse errors in Solana RPC and GitHub checks, returning 'degraded' instead of falling through to connection_error handler - Run all four health probes concurrently with asyncio.gather() to avoid stacking 200ms timeouts under sequential awaits - Decouple integration test mock helper from AsyncClient construction order by patching _check_solana_rpc/_check_github_api directly - Add missing test cases: malformed_response, unauthenticated low limit --- backend/app/api/health.py | 36

convert async tests to sync via run_async; fix malformed-response handling - Replace @pytest.mark.asyncio with run_async() helper to avoid 'no current event loop' errors in STRICT asyncio mode (pytest-asyncio 0.26) - Add isinstance(data, dict) guard in _check_solana_rpc and _check_github_api so non-dict responses from resp.json() fall into malformed_response branch instead of leaking to the generic connection_error handler - Use _patch_all_external_healthy() that patches helpers directly, decoupling endpoint tests from AsyncClient construction order - Add latency_ms to all reachable-but-failed branches (timeout, http errors) for consistent monitoring dashboard support --- backend/app/api/health.py | 6 + backend/tests/test_health.py | 229
