node.js - Mongoose hangs forever when replica set is not given -


here's way connect mongodb replica set mongoose:

var connectionstring = 'mongodb://user:password@primary:27017,secondary1:27017,secondary2:27017/dbname?authmecanism=mongodb-cr&replicaset=myset'; var options = { usemongoclient: true }; mongoose.connect(connectionstring, options, error => {     if (error) throw error;     console.log('database on'); });

if give wrong credentials, connection fail.

if give wrong ips, query end in etimedout.

however if remove replicaset parameter in connection string, "find" query run forever: won't time out , won't enter callback either.

is there event listen in case?

ps: don't know if relevant i'm using mongo 3.3 mongoose 4.11.

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
