It seems I've got another problem with nonblocking Connect method. When I'm trying to connect in nonblocking mode from a simple client to a simple server my app generates error message after I call Do():
ws.NonBlocking().Connect("ws://127.0.0.1:8888");
ws.Do();
In nonblocking mode Connect() just sets opcode variable in DNS state and makes no operations until Do() is called:
if(socket->IsBlocking())
...
else
opcode = DNS;
return true;
In Do0 there is if-statement listed below:
if(socket->IsEof() && !(close_sent || close_received))
Error("Socket has been closed unexpectedly");
And in the IsEof method there is checkup for socket's descriptor state:
bool TcpSocket::IsEof() const
{
return is_eof && ptr == end || IsAbort() || !IsOpen() || IsError();
}
As far as I can understand IsOpen returns true since the socket was not opened. So I can't process DNS state and make connection in nonblocking mode.
I used upp sources from github: 993904e
Compiler: GCC 5.4.1
