fix: handle RecursionError in Flow.serialize_parameters (#22245)

main

30 minutes ago

fix: handle RecursionError in Flow.serialize_parameters jsonable_encoder recurses into unknown objects with no cycle or depth limit, so a deeply-nested or self-referential parameter raises RecursionError. That is a RuntimeError, not TypeError/ValueError, so it escaped the existing placeholder fallback and crashed the flow run. Catch it too and fall back to the '<Type>' placeholder, same as any other unserializable value. Closes #22244

fix(server): URL-encode credentials in asyncpg LISTEN/NOTIFY DSN closes #22088 Raw string manipulation on the connection URL preserved unencoded special characters in passwords (#, ?, <), which broke asyncpg's internal urlsplit() and silently disabled LISTEN/NOTIFY. Use SQLAlchemy's render_as_string(hide_password=False) to percent-encode credentials. _normalize_asyncpg_dsn_query_params then collapses repeated multihost host= params, and asyncpg decodes the encoded values back when it parses the DSN.

fix(runner): degrade events WebSocket on transient connection failures - EventEmitter only caught HTTP 4xx rejections (InvalidStatus), so a transient events-WebSocket failure (handshake timeout, dropped connection, network error) propagated out of FlowRunExecutorContext and crashed the flow run with exit(1) - add RETRYABLE_EXCEPTIONS (ConnectionClosed, TimeoutError, OSError) to _NONFATAL_CONNECTION_EXCEPTIONS so any connection failure degrades to NullEventsClient and the flow run continues; events are non-critical telemetry (the runner emits only prefect.runner.cancelled-flow-run) - reuse the events client's RETRYABLE_EXCEPTIONS so the retryable and non-fatal exception sets stay defined in one place - reword the degradation warning to fit both rejection and timeout; the client-upgrade hint is now conditional on server authentication - add parametrized tests for TimeoutError/OSError degradation and update runner AGENTS.md to document both failure classes
