Second, deeper pass over tools/gateway/hermes_cli plus first pass over
the trees wave 1 missed (acp, acp_adapter, skills, computer_use, docker,
dashboard, conformance, monitoring, secret_sources, hermes_state,
providers). Same rubric as wave 1 (AGENTS.md test policy); security,
alternation/caching invariants, issue-number regressions, and E2E kept.
Real test-quality fixes found and rooted out along the way:
- tests/tools/test_command_guards.py made real auxiliary-LLM HTTPS calls
(DEFAULT_CONFIG smart-approval leaked in) — pinned approval
mode=manual via autouse fixture: 17.4s → 0.4s.
- test_model_switch_custom_providers.py / test_user_providers_model_switch.py
silently probed live provider catalogs (~2s/test) — stubbed
cached_provider_model_ids/provider_model_ids/fetch_api_models.
- test_telegram_noise_filter.py: 15-platform copy-paste matrix over
shared gateway.run logic → 3 representative platforms (55s → 3.9s).
- test_gateway_shutdown.py: stop()'s 5s interrupt-deadline loop spun on
MagicMock agents — interrupt.side_effect now clears _running_agents
(22s → 1.0s).
- test_gateway_inactivity_timeout.py poll-harness timings shrunk 3-5x
(24s → 1.1s); test_mcp_stability.py backoff/SIGTERM-grace sleeps
patched (15.4s → 2.5s); test_async_delegation.py negative-drain wait
5s → 0.5s.
- test_telegram_init_deadline.py: loop-block margin restored to 1.0s
with rationale comment — the watchdog-dump assertion needs the loop
blocked well past deadline+grace under parallel load (flaked once in
the 40-worker verification run at a 0.2s margin).
Verification: full hermetic suite via scripts/run_tests.sh —
2,438 files, 21,718 tests passed, 0 failed, 293.9s wall.
Suite totals vs original baseline: 46,820 → 19,757 test functions
(−57.8%), wall 583.5s → 293.9s (−50%), subprocess CPU 13,564s → 11,623s.
The merged webhook session-close fix (#57370, salvaging #57322) wrapped
handle_message in a try/finally — but BasePlatformAdapter.handle_message
is fire-and-forget: it spawns _process_message_background and returns
before the agent run starts. The finally-close therefore ran BEFORE
get_or_create_session created the session row, found no session_id, and
silently no-op'd — the ghost-session leak persisted on the real path.
(The shipped test masked this by stubbing handle_message with a fake
that created the row synchronously.)
Move the close to an on_processing_complete override — the lifecycle
hook the base class fires at the TRUE end of the run, on the success,
failure, and cancellation paths alike. Empirically verified through the
real fire-and-forget pipeline: before, ended_at stayed NULL; after,
ended_at is set with end_reason=webhook_complete and the row is
prunable.
Tests now stub only the runner-side _message_handler (the seam the live
gateway injects) so handle_message / _process_message_background /
on_processing_complete all run for real; adds an AsyncSessionDB-facade
coverage test for the coroutine-await branch.
Replace the webhook delivery-close path's direct reach into private
SessionStore._entries (which also bypassed the store lock) with a public,
lock-held peek_session_id(session_key) accessor. Mirrors the existing
lookup_by_session_id inverse helper. Keeps a getattr fallback for older
stores / test doubles. Adds a unit test for the accessor.
Webhook deliveries created a unique one-shot session (delivery_id baked into
the session key at gateway/platforms/webhook.py:668) but the adapter fired
handle_message via asyncio.create_task WITHOUT ever ending the session
(webhook.py:713, pre-fix). Nothing else closes it: the gateway caches/expires
the agent per session_key but never calls end_session for the webhook path,
and _end_session_on_close teardown doesn't run for these fire-and-forget tasks.
SessionDB.prune_sessions (hermes_state.py:4965) only deletes rows WHERE
ended_at IS NOT NULL. So every webhook session stayed with ended_at NULL ->
unprunable -> unbounded state.db growth. This was the primary driver of the
SQLite lock-contention gateway outage.
Fix: wrap the delivery in _run_delivery_and_close, which awaits
handle_message and then (in finally, so failures still reap) calls
_end_webhook_session -> SessionDB.end_session(session_id, 'webhook_complete').
This mirrors how cron closes its session with 'cron_complete'
(cron/scheduler.py:3065). end_session is first-reason-wins and no-ops on an
already-ended row, so it never clobbers a compression/agent_close reason.
Adds tests/gateway/test_webhook_session_close.py asserting the invariant
(a completed webhook session has ended_at set + is prunable), including the
error-path case, against a real SessionStore + SessionDB.
