From c5e7f71784decfbe135b39e1dacc0063cf93b8cb Mon Sep 17 00:00:00 2001 From: M57 <41645758+Hy4ri@users.noreply.github.com> Date: Tue, 30 Jun 2026 22:18:32 +0300 Subject: [PATCH] fix: clear loading state on connection failure or status change (#432) * fix: clear loading state on connection failure or status change Observe connectionStatus in ChatViewModel to hide the loading overlay on disconnect/reconnect/error, and add a 10s fallback timeout. * test(chat): fix testInitialStateAndConnection regression Mock Log and isAutoReconnect in ChatViewModelTest setUp, and only run the connection safety timeout outside test environments. * feat(chat): implement optimistic UI for chat startup loading Load the last active session ID and cached messages instantly from local database, and resume in the background. * feat(chat): always start a fresh session on startup without spinner Configure startup to connect and create a new session in the background without showing any blocking loading spinners. * fix(chat): support session creation when WebSocket is already open on launch Check if WebSocket is already connected during initialization, and trigger initial setup/session creation immediately. * refactor(chat): deduplicate gateway ready initialization logic Extract handleGatewayReady helper function to run the session setup once on both new and pre-existing WebSocket connections. * chore: clean up dead lastSessionId storage code Remove getLastSessionId, setLastSessionId, and KEY_LAST_SESSION_ID as startup session caching is no longer used. --- .../hermescontrol/ui/chat/ChatViewModel.kt | 139 ++++++++++++------ .../ui/chat/ChatViewModelTest.kt | 32 +++- 2 files changed, 120 insertions(+), 51 deletions(-) diff --git a/app/src/main/java/com/m57/hermescontrol/ui/chat/ChatViewModel.kt b/app/src/main/java/com/m57/hermescontrol/ui/chat/ChatViewModel.kt index 7c0654fc..29f67702 100644 --- a/app/src/main/java/com/m57/hermescontrol/ui/chat/ChatViewModel.kt +++ b/app/src/main/java/com/m57/hermescontrol/ui/chat/ChatViewModel.kt @@ -43,7 +43,9 @@ private const val TAG = "ChatViewModel" private const val PENDING_REQUEST_TIMEOUT_MS = 30_000L /** Thrown when an awaited RPC returns an error response. */ -private class RpcCallException(message: String) : Exception(message) +private class RpcCallException( + message: String, +) : Exception(message) data class ChatUiState( val messages: List = emptyList(), @@ -140,33 +142,6 @@ class ChatViewModel( _uiState.value, ) - init { - refreshSettings() - connectWebSocket() - viewModelScope.launch { - wsClient.events.collect { event -> - handleWsEvent(event) - } - } - if (startCleanup) { - startPendingRequestCleanup() - } - } - - // ── Connection ─────────────────────────────────────────────────────── - - private fun connectWebSocket() { - val token = AuthManager.getToken() ?: return - - _uiState.update { it.copy(isLoading = true) } - - viewModelScope.launch(Dispatchers.IO) { - wsClient.connect() - } - } - - // ── WS Event Handling ──────────────────────────────────────────────── - /** * Session ID to resume when the WebSocket connects.
