The previous canvas-default 5-min absolute deadline pre-empted any
chat that legitimately ran longer (multi-turn tool use, large
synthesis tasks) and made every wedged-SDK call burn 5 full minutes
before the user saw anything. Replaced with a per-dispatch idle
timeout: cancel the request only when the broadcaster has been
silent for `idleTimeoutDuration` (60s). Any progress event for the
workspace — agent_log tool-use rows, task_update, a2a_send,
a2a_receive — resets the clock.
Mechanics:
- new applyIdleTimeout helper subscribes to events.Broadcaster's
per-workspace SSE channel, drains its messages, resets a
time.Timer on each one, cancels the wrapped ctx when the timer
fires. Cleanup goroutine + subscription lives only as long as
the returned cancel func is uncalled.
- dispatchA2A now takes workspaceID as a parameter, applies the
idle timeout always (canvas + agent), and combines its cancel
with the existing 30-min agent-to-agent ceiling cancel into one
func the caller defers.
- Canvas dispatches no longer have an absolute ceiling at all —
the idle timer is the only "give up" signal. A healthy chat
reporting tool-use telemetry every few seconds runs forever;
a wedged runtime fails in 60s instead of 5 min.
- isUpstreamBusyError now also recognises context.Canceled (the
error class our idle cancel produces, distinct from
DeadlineExceeded). Same 503-busy retry semantics.
Tests:
- TestApplyIdleTimeout_FiresOnSilence — 60ms idle, no events,
ctx cancels with context.Canceled.
- TestApplyIdleTimeout_ResetsOnEvent — event mid-window extends
the deadline; ctx alive past original deadline, then cancels
on the second silence window.
- TestApplyIdleTimeout_NilBroadcasterDegradesGracefully — defensive
no-op for paths that don't wire a broadcaster.
- 3 existing dispatchA2A tests updated for the new workspaceID
param + the always-non-nil cancel return shape.
