When a gateway session hits a non-retryable error (e.g. invalid model ID → HTTP 400), the agent fails and returns. But if the session keeps receiving messages (or something periodically recreates agents), each attempt spawns a new AIAgent — reinitializing MCP server connections, burning CPU — only to hit the same 400 error again. On a 4-core server, this pegs an entire core per stuck session and accumulates 300+ minutes of CPU time over hours. Fix: add a per-session consecutive failure counter in the gateway runner. - Track consecutive non-retryable failures per session key - After 3 consecutive failures (_MAX_CONSECUTIVE_FAILURES), block further agent creation for that session and notify the user: '⚠️ This session has failed N times in a row with a non-retryable error. Use /reset to start a new session.' - Evict the cached agent when the circuit breaker engages to prevent stale state from accumulating - Reset the counter on successful agent runs - Clear the counter on /reset and /new so users can recover - Uses getattr() pattern so bare GatewayRunner instances (common in tests using object.__new__) don't crash Tests: - 8 new tests in test_circuit_breaker.py covering counter behavior, threshold, reset, session isolation, and bare-runner safety Addresses #7130. |
