Create and Connect many sockets crashes/hangs

[lightsprint09]

Running the following test code hangs after connecting to a some Socket clients and all other clients time out. I think this isn't normal behavior.

func testMasstivConnect() {
      weak var expection = expectationWithDescription("massiv")
        var list = Array<SocketIOClient>()
        let count = 90
        for _ in (0..<count) {
            let newSocket = SocketIOClient(socketURL: "http://localhost:6979")
            openConnection(newSocket) {
                list.append(newSocket)
                print(list.count)
                if list.count == count {

                    expection?.fulfill()
                }
            }
        }
        waitForExpectationsWithTimeout(30.0, handler: nil)
    }
func openConnection(socket: SocketIOClient, isConnectedCallback:()->()) {
        if socket.status == .Connected {
            isConnectedCallback()
        }
        socket.on("connect") {data, ack in
            dispatch_async(dispatch_get_main_queue(), {
                XCTAssertEqual(socket.status, SocketIOClientStatus.Connected)
                XCTAssertFalse(socket.secure)
                isConnectedCallback()
            })

        }
        socket.connect(timeoutAfter: 29, withTimeoutHandler: {
            print("Did Timout connect")
        })
    }

I would think that would be some kind of problem with NSURLSession or something along those lines. Have you tried testing this with forced WebSocket?

[lightsprint09]

with let newSocket = SocketIOClient(socketURL: AbstractSocketTest.serverURL, options: [.ForceWebsockets(true)])
Every connection times out

[nuclearace]

Is there a set number of connections that it opens before they subsequently start failing?

[lightsprint09]

Without forced WebSockets about 20-60.

[nuclearace]

20-60 is a pretty large range. Have you tried testing some sort of rate limiter? Also is there some sort of error message that happens?

[lightsprint09]

ok 63 work, 64 doesn't

[nuclearace]

What platform are you testing on?

[lightsprint09]

Mac OS

[nuclearace]

When I test this outside of XCTest it seems to work.

let NUM_SOCKETS = 90
var connects = 0
let sockets = [SocketIOClient](count: NUM_SOCKETS, repeatedValue: SocketIOClient(socketURL: "localhost:8080"))

for socket in sockets {
    socket.on("connect") {data, ack in
        connects++
    }
    socket.connect()
}

let waitTime = dispatch_time(DISPATCH_TIME_NOW, Int64(1 * NSEC_PER_SEC))
dispatch_after(waitTime, dispatch_get_main_queue()) {
    assert(connects == NUM_SOCKETS, "Did not connect all sockets: \(connects)")
}

[nuclearace]

Anymore on this?

[nuclearace]

@lightsprint09 Anymore on this?

[lightsprint09]

Did not have the time to investigate any further

[nuclearace]

I think it has to do with daltoniam/Starscream#153 in which there's nothing really we can do.
