* fix(ws): align RPC timeout to 120s + rejectAllPending on disconnect (fixes#526)
Mobile's pending-request handling diverged from the desktop contract
(apps/shared JsonRpcGatewayClient) in two ways that caused silent hangs:
1. Timeout was 30s while the desktop uses 120s (DEFAULT_REQUEST_TIMEOUT_MS),
so legitimately long agent turns were pruned early. Align to 120s and use
it for both the cleanup sweep and sendRpcAndAwait's per-call withTimeout.
2. The cleanup sweep only Log.w'd stale requests and dropped them — it never
failed the CompletableDeferred, so sendRpcAndAwait callers awaiting a
server that never answered HUNG FOREVER. And on disconnect/reconnect there
was NO rejectAllPending, so in-flight awaited RPCs also hung until their
own timeout.
Changes (all in ChatViewModel.kt):
- cleanup sweep now completeExceptionally()s the deferred AND surfaces a
'Request timed out' error for fire-and-forget RPCs (was silently dropped)
- new rejectAllPending() fails + clears every in-flight pending deferred;
wired into the disconnect-status collector and reconnect()
- PENDING_REQUEST_TIMEOUT_MS = 120_000 (matches desktop); sendRpcAndAwait
uses it instead of a hardcoded 30s
Tests: 2 new ChatViewModelTest cases cover rejectAllPending on disconnect
and on reconnect (no hang, VM stays usable). (Timeout-surfacing path shares
the deferred-fail logic with handleRpcError; the 120s sweep can't run under
the unit-test dispatcher's periodic-timer limitation, noted in PR.)
Mirrors the desktop-app audit in /opt/hermes-agent.
* fix(ws): aggregate pending-request cleanup into a single UI update (PR #541)
Sourcery review (PR #541): startPendingRequestCleanup emitted one
_uiState.update{} per stale request inside the loop, causing N separate
emissions / redundant recompositions when many RPCs time out at once.
Collect fire-and-forget methods and emit a single combined errorMessage
update after the loop.
rejectAllPending is intentionally left silent on disconnect/reconnect:
those are transient socket events (the RPC often completes on the new
socket), so surfacing a scary error banner is UX noise. Only the
timeout path surfaces errors — that is a genuine failure. This matches
the desktop JsonRpcGatewayClient.rejectAllPending semantics.
* refactor(ws): move awaited-RPC pending/timeout layer into HermesWsClient (closes#526)
Issue #526: port the JsonRpcGatewayClient.request() pattern into
HermesWsClient. HermesWsClient now owns the in-flight map, per-call
120s timeout, resolve-on-RpcResult/RpcError, and rejectAllPending on
disconnect/reconnect. ChatViewModel.sendRpcAndAwait simply delegates
to wsClient.request(...).await(); its local pendingRequests map,
PendingRequest, startPendingRequestCleanup loop and rejectAllPending
are removed. Fire-and-forget send() is unchanged.
