// GeneralsX @feature GeneralsOnline NGMP UI Binding - Added RefreshNGMPGameListBoxes to LobbyUtils for populating the UI - Added chat session initialization upon EVENT_AUTH_SUCCESS - Hooked WOLLobbyMenuUpdate to poll NGMP events instead of GameSpy - Replaced TheGameSpyInfo->sendChat with NGMP sendChatMessage - Modified OnlineServices_Manager update() to return events (pollEvents) - Ensured shell event pump mechanism is using pollEvents
Added async polling for Global Stats and Persona Stats via NGMP endpoints instead of relying on GameSpy functions, allowing the UI to populate the Persona panel and Welcome screen statistics. Fixed the Communicator window auto-closing by using the NGMP login state instead of the GameSpy network state.
When the client connected to the WebSocket for NGMP Custom Match lobbies, it never sent a NETWORK_ROOM_CHANGE_ROOM message to join a specific room. As a result, the server treated the client as being in room -1, causing the Lobbies HTTP request to return 0 lobbies, and the client never received player list updates (msg_id 4) or chat messages. Added changeNetworkRoom(int16_t roomID) to NGMP_OnlineServicesManager and called it with room 0 (Global Lobby) in WOLLobbyMenuInit before requesting the lobby list asynchronously. Also documented this requirement in ngmp.instructions.md.
…ering WOLLobbyMenuUpdate was calling TheShell->pop() before calling markAsStagingRoomHost() in the EVENT_LOBBY_CREATED handler. Because buttonPushed=true at that point, Shell::pop() triggers WOLLobbyMenuShutdown with popImmediate=TRUE, which synchronously executes shutdownComplete -> TheShell->push -> WOLGameSetupMenuInit. Inside WOLGameSetupMenuInit, getCurrentStagingRoom() returned nullptr (m_isHosting was still FALSE), causing a SIGSEGV on game->getSlot(0). Fix: call markAsStagingRoomHost()/markAsStagingRoomJoiner() BEFORE TheShell->pop() so the staging room state is initialized before any synchronous init chain can fire. Also add a defensive null-check in WOLGameSetupMenuInit for getCurrentStagingRoom() that pops back to the lobby if nil, preventing any future crash from an unexpected state loss. Add diagnostic stderr logs in PopupHostGame and WOLLobbyMenu to trace createLobbyAsync invocation and staging room transitions.
GameEngine.cpp was calling pollEvents() every frame, which consumed and discarded all pending UI events (like EVENT_LOBBY_CREATED) if they arrived between menu updates. This caused a race condition where the 'Create Game' flow would successfully create a lobby on the server, but the UI menu would never transition to the staging room setup screen. Fix: Split pollEvents() into update() and pollEvents(). - update(): Processes internal logic (WebSocket messages) and moves UI events to a new m_uiEventQueue. - pollEvents(): Now exclusively polls m_uiEventQueue for the UI menus. - GameEngine::update() now correctly calls NGMP_OnlineServicesManager::update() instead of pollEvents(). Also added fallback for PascalCase vs camelCase in lobby parsing (Name/name) and added a diagnostic log to capture the Lobbies API JSON response.
GameSpy slots require an explicitly set identity (TheGameSpyInfo->setLocalName) which was previously missing in the NGMP login flow, causing the host slot to be blank. Also fixed the Back button in WOLGameSetupMenu doing nothing because it incorrectly relied on checking if the GameSpy P2P peer socket was connected before popping the screen. Now it unconditionally pops and calls NGMP changeNetworkRoom(0) to leave the lobby.
libcurl does not support concurrent access to the same CURL handle. When the main thread called curl_ws_send or curl_easy_cleanup while the receive thread was running curl_ws_recv, the allocator corrupted and crashed the game with SIGABRT (malloc bug pointer being freed was not allocated). Now both receive and send are synchronized over m_sendMutex.
…obby 1. Populate TheGameSpyInfo localName and profileID upon NGMP login in OnlineServices_Manager and MainMenuUpdate so the host player name displays properly in room slots. 2. Hide ping indicator for the local player slot in WOLGameSetupMenu, following references/GameClient pattern. 3. Push WOLCustomLobby.wnd upon game completion in WOLGameSetupMenuInit for NGMP builds.
- Populate custom lobby player listbox from NGMP lobby players with rank icons - Fix chat message JSON payload schema and listbox routing - Restore classic Welcome to Generals Online voice line on login - Gate voice line playback to once per session with transition safety guards - Backport welcome menu improvements to Generals base game - Update August 2026 worklog
…ndency - Move RefreshNGMPGameListBoxes from shared Core LobbyUtils to WOLLobbyMenu to decouple base game from Zero Hour NGMP headers - Bundle json.hpp and update NGMP_json.h with fallback header resolution for offline/sandboxed Flatpak environments - Safeguard FetchContent in cmake/ngmp.cmake when FETCHCONTENT_FULLY_DISCONNECTED is enabled - Update August 2026 worklog
…rver config - Defer browser login and CheckLogin polling to explicit user action when entering Multiplayer -> Online - Add .ngmp-config.cmake generation in flatpak-builder script and cmake/ngmp.cmake - Propagate NGMP server secrets to GitHub Actions build workflows - Update August 2026 worklog
…icate config - Remove duplicate NGMP compile definitions in cmake/config-build.cmake - Generate non-hidden cmake/ngmp_env.cmake for flatpak-builder sandbox inclusion - Prioritize CLI and cached host definitions in cmake/ngmp.cmake - Update August 2026 worklog
…ease crt on windows
…nition On Windows MSVC, bittype.h previously typedef'd uint32 as unsigned long, while steamtypes.h (GameNetworkingSockets) defines uint32 as unsigned int. In C++, unsigned long and unsigned int are distinct types even if both are 32-bit, causing error C2371: 'uint32': redefinition; different basic types when compiling Zero Hour network units. Using uint32_t universally resolves the conflict.
Tick NGMP_OnlineServicesManager during GameSpyLoadScreen and MapTransferLoadScreen to prevent WebSocket signaling stalls while loading maps. Call NetworkMesh::Tick in NextGenTransport::update on every transport cycle to advance the ICE state machine and flush pending packets. Add GameNetworkingSockets debug output function and SendSignal logging in NetworkMesh to diagnose ICE candidate routing.
…rvation - Clear P2P_TURN_ServerList, UserList, and PassList in NetworkMesh and SetTURNCredentials - Enforce ICE flags to Private and Public only (no Relay) to prevent infinite thinker loops on non-standard UDP TURN endpoints - Resolves GNS service thread lockup and allows immediate dispatch of ConnectOK and ICE candidates - Update worklog diary for 07/09/2026

In @.github/workflows/build-windows.yml:
- Line 105: Update the cache key expression in the vcpkg cache restore flow to
reference the valid steps.vcpkg_cache output name, cache-primary-key, instead of
primary-key, while preserving the existing fallback key behavior.
In @.github/workflows/replay-tests-windows.yml:
- Around line 255-256: Update the exit-code formatting logic around $timedOut
and $exitCode so the "timeout" sentinel is handled before any [int64]
conversion. Preserve the existing hexadecimal formatting for numeric nonzero
exit codes with empty $output, while allowing timed-out replays to continue
writing their FAIL row and final totals.
In `@Core/Libraries/Source/WWVegas/WWLib/bittype.h`:
- Around line 49-51: Add a VC6-compatible fixed-width integer fallback around
the uint32_t and int32_t aliases in bittype.h, avoiding an unconditional
dependency on stdint.h while preserving the uint32 and sint32 names and their
32-bit signedness across modern platforms.
In
`@Generals/Code/GameEngine/Source/GameClient/GUI/GUICallbacks/Menus/WOLWelcomeMenu.cpp`:
- Line 92: Replace the direct ShellExecuteA browser launch in the WOLWelcomeMenu
implementation with SDL3 SDL_OpenURL or the established platform browser
abstraction. Apply the same change in
Generals/Code/GameEngine/Source/GameClient/GUI/GUICallbacks/Menus/WOLWelcomeMenu.cpp
lines 92-92 and
GeneralsMD/Code/GameEngine/Source/GameClient/GUI/GUICallbacks/Menus/WOLWelcomeMenu.cpp
lines 98-98, preserving the existing URL-opening behavior.
In
`@GeneralsMD/Code/GameEngine/Source/GameNetwork/GeneralsOnline/NetworkMesh.cpp`:
- Around line 388-392: Update the bAllowedPeer authorization logic in
AcceptConnection to rely on authenticated lobby membership, not
connections.count(connectionID), because the incoming identity may already have
been inserted into connections. Remove the newly inserted-connection
authorization path; if an existing outgoing-connection exception is required,
capture and validate that state before processing the incoming identity.
- Around line 653-660: Update NetworkMesh::SetTURNCredentials and the ICE
configuration so peers requiring TURN retain a working GameNetworkingSockets
game-data path. Resolve the documented thinker-starvation loop before enabling
TURN, or provide a separate relay for game packets; do not rely on the NGMP
WebSocket, which only carries NETWORK_SIGNAL messages.
