bug: depth cache is crashing #207

Closed mor-o closed 6 years ago

mor-o commented 6 years ago

Short Description: node-binance-api crashed after using depth cache for long period of time.

Platform: windows

node version:

Long descrption in the logs below you can see it gets 504 from the server and keeps trying. at some point it seems to be losing sync for some symbols and than the exception occurs. this is the second time it happens but this time i had it on verbose. both times it append after binance listed a new coin. could that be the reason for the exception? btw i am working with release v0.4.29

@mor-o can you please update your software to the lastest version and provide additional information

looking at 1520 in our code suggest you are on an old version.

I am working with the latest release and saw this error today twice after some time.

depthHandler and Combined Stream messages we're repeated endlessly - I had to restart my bot to take care of it. Then a new websocket subscription went flawlessly.

Waiting for the debugger to disconnect...

looks like sometimes when reconnecting, we get a symbol that was not initialized, otherwise it would have had context.messageQueue defined :

let symbolDepthInit = function(symbol) {
    if ( typeof depthCacheContext[symbol] === 'undefined' ) depthCacheContext[symbol] = {};

    let context = depthCacheContext[symbol];
    context.snapshotUpdateId = null;
    context.lastEventUpdateId = null;
    context.messageQueue = [];

    depthCache[symbol] = { bids: {}, asks: {} };
};

i can see that we are not initializing all symbols in the callback of subscribe in line 1670

else {
    let symbol = symbols;
    symbolDepthInit(symbol);
    subscription = subscribe(symbol.toLowerCase()+'@depth', handleDepthStreamData, reconnect, function() {
        getSymbolDepthSnapshot(symbol);
    });
}

maybe we should?
