Also auto-start the ping process in InitBackend3(). --- diff --git a/backend.c b/backend.c index ca839ca..65fc44b 100644 --- a/backend.c +++ b/backend.c @@ -187,6 +187,7 @@ void DisplayMove P((int moveNumber)); void ParseGameHistory P((char *game)); void ParseBoard12 P((char *string)); +void KeepAlive P((void)); void StartClocks P((void)); void SwitchClocks P((void)); void StopClocks P((void)); @@ -244,6 +245,7 @@ char endingGame = 0; /* [HGM] crash: flag to prevent recursion of GameEnds() int whiteNPS, blackNPS; /* [HGM] nps: for easily making clocks aware of NPS */ VariantClass currentlyInitializedVariant; /* [HGM] variantswitch */ int lastIndex = 0; /* [HGM] autoinc: last game/position used in match mode */ +Boolean connectionAlive;/* [HGM] alive: ICS connection status from probing */ int opponentKibitzes; int lastSavedGame; /* [HGM] save: ID of game */ char chatPartner[MAX_CHAT][MSG_SIZ]; /* [HGM] chat: list of chatting partners */ @@ -1121,6 +1123,8 @@ InitBackEnd3 P((void)) AddInputSource(icsPR, FALSE, read_from_ics, &telnetISR); fromUserISR = AddInputSource(NoProc, FALSE, read_from_player, &fromUserISR); + if(appData.keepAlive) // [HGM] alive: schedule sending of dummy 'date' command + ScheduleDelayedEvent(KeepAlive, appData.keepAlive*60*1000); } else if (appData.noChessProgram) { SetNCPMode(); } else { @@ -1440,6 +1444,8 @@ read_from_player(isr, closure, message, count, error) void KeepAlive() { // [HGM] alive: periodically send dummy (date) command to ICS to prevent time-out + if(!connectionAlive) DisplayFatalError("No response from ICS", 0, 1); + connectionAlive = FALSE; // only sticks if no response to 'date' command.
