Root cause: idalib workers run an idle watchdog (worker_lifecycle.py) that
self-exits after idle_ttl_sec (default 600s) of no requests -- deliberate
resource hygiene for a shared/ephemeral supervisor, wrong for an interactive
TUI. CLI-opened startup binary always gets 600s (no flag).
Fix (both verified against a 12s-TTL session):
- IDAClient.bump_idle_ttl(1e9): re-open (idempotent) re-applies TTL, no upper
cap -> effectively immortal. Primary fix, call once at startup.
- IDAClient.keepalive()/KeepAlive: background server_health heartbeat resets the
watchdog; covers adopted sessions too. Safety net.
tests/test_keepalive.py: 4/4 (heartbeat + bump both keep a short-TTL worker
alive past 2x TTL). docs updated with why + fix.
harden client: transparent session auto-recovery + stress suite2026-07-09T09:22:18Zblastyblasty@local2026-07-09T09:22:18Zurn:sha1:90636755b26c5dbee8acdda5e37c7aff9e896854
- auto-recover stale db ("Session not found" after server restart): drop pin,
re-resolve sole session, retry once. Only when db was auto-injected; never
silently switches an explicitly-pinned db (auto_recover_session gate).
- tests/serverctl.sh: start/stop/kill9/ready control over spawn.sh
- tests/stress_client.py: 6 adversarial scenarios, 24 assertions:
dead-port fail-fast, tight-timeout recovery, worker crash, full restart
(naive auto-recovery + no-autoswitch), 300/16 concurrency, kill-under-churn.
All clean: no hangs, no deadlocks, no non-IDAError leaks.
persistent MCP client: warm handshake, keep-alive pool, error taxonomy, thread-safe2026-07-09T09:14:23Zblastyblasty@local2026-07-09T09:14:23Zurn:sha1:eec630887ce72a7dafae4c33f5e85ad7c746b038
- IDAClient: single handshake, ~7ms warm calls (vs ~60ms cold CLI)
- keep-alive connection pool over http.client; concurrent-safe (40 threads OK)
- grounded error taxonomy: IDAToolError on isError, soft per-item errors as data
- session-expiry recovery (404 -> re-handshake -> retry), bounded transport retries
- auto db-injection + resolve_db (ignores stale empty-id sessions)
- live smoke test: 13/13 pass
