failover to secondary end-point about socket2me

[MrPeanutButta]

I need to find a way to correctly test on distributed servers. I'm seeing issues with spinning up multiple servers on a single machine. I think it's because of it's static and multi-threaded design.

Tested with 3 servers. Fails over as expected.
NOTE: test servers tend to hang and not release sockets very well.

hi, ahebet, thanks for your excellent work.
i have a question, i run the socket server, and then run a client connect to the socket server.
then i kill the client process, i found the server's memory is increasing fast.
i doubt there is memory leak when i kill the client, can you give me some clues ?
thank you very much !

Hi Husong, Thanks for your question. Could you send me a code example that reproduces this problem? I will have to investigate this.

@ahebert , sorry for late reply,

1、i start a server like following:

` unique_ptr s(new server("vcm_plugin_auth", auth::MD5));

s->set_read_callback(server_receive);
s->listen("0.0.0.0", port);

while(1)
{
    this_thread::sleep_for(chrono::seconds(50));
}`

---

2、and then start a client without addfailover

` unique_ptr c(new client("vcm_plugin_auth", auth::MD5));

static int i = 0;

 while(!c->authenticate(ip_addr, port))
{
    cout<< "authenticate fail, please check the server ip and port is correct " << endl;

    client_s(to_string(++i));
    i = i < 10 ? i : 3;

    this_thread::sleep_for(chrono::seconds(kHeartBeatInterval));
};

do {

    while (c->connected()) 
    {

        auto uuid(c->getUUid());
		
		//do something
		
        this_thread::sleep_for(chrono::seconds(kHeartBeatInterval));
    }

    client_s(to_string(++i));
    i = i < 10 ? i : 3;

    this_thread::sleep_for(chrono::seconds(kHeartBeatInterval));

    cout << "attempting failover" << endl;

} while (c->failover());`

3、when i kill the client process , the server memory increasing fast ,
maybe i have wrong way to use your software, could you review my code,
and give me some advices? thanks a lot

@songbaoer I've opened a new bug to track this. Please refer to #10 for this issue going forward.
I'll investigate this.

Thanks,
