Root cause: librlottie RleTaskScheduler creates 32 worker threads on first
lottie_animation_from_data call. These pthreads wait in WaitForMultipleObjects(INFINITE)
and never exit. On MinGW, exit()/pthread_join blocks forever.
Changes:
- messagelist: s_icons moved to file-static; cleanupAnimations() clears them,
calling lottie_animation_destroy BEFORE static destruction
- mainwindow: ~MainWindow calls MessageList::cleanupAnimations() after node stop
- main: ShutdownSentinel counts threads at exit; if >4 remaining, calls
ExitProcess(0) to bypass CRT pthread_join hang
- main: if rlottie properly shuts down (<=4 threads), normal return (no ExitProcess)
Signal handler via g_shutdown + uasync_wakeup ensures clean uasync poll exit.
updateReadPosition() now saves both lastReadMsgId and lastPosMsgId on every
scroll stop (300ms debounce), not just when read position changes.
connect(stopped, quit) triggers graceful Qt shutdown after uasync cleanup.
Replace gui_bridge_post_uasync_fn (async queue lost on shutdown) with direct
chat_core_save_ui_state (sync SQLite write). SQLite WAL handles concurrent access.
Add DEBUG_DEBUG traces in closeEvent, ~MainWindow, aboutToQuit.
Add author_node_id:8 to GUI_EVT_MSG_RECEIVED data format.
Callback now includes uint64_t author parameter.
SoundManager::play('msg_incoming') only when author != myNodeId.
- Same-channel refresh: save scroll pos in memory, restore from memory (no DB race)
- Force m_readDebounce->start() after loadChannel (scrollToBottom may not trigger valueChanged)
- DEBUG_DEBUG logs in updateReadPosition, saveChannelState, onMessageReceived, setChannelUnreadCount
- Debounce timer (300ms) advances lastReadMsgId only when message is fully in viewport
- Unread badge no longer resets on channel select — only when actual scroll reads msgs
- saveChannelState() uses tracked m_lastReadMsgId instead of viewport bottom
- getChannels() reads lastReadMsgId from ui_state (was reading unused channels column)
Store read/scroll positions per channel via ui_state table (key-value).
Draw red +N badge on channel list items for unread messages.
Fix getMessages() to fetch last N messages (was fetching first N).
