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.

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
