Network / sf::SocketSelector limited to 64 connections on Windows?

« on: August 14, 2011, 10:35:37 am »

I had the same problem about year ago.
Windows event system is designed to handle max. 64 items, if you need more you should use threads - thats what i found on microsoft side.
I havent found any limits for linux (also ubuntu in my case) but its possible that i havent tested selectors for more than 1024 sockets.

For my second question answer is here:
http://stackoverflow.com/questions/411295/alternatives-to-winsock2-with-example-server-source-in-c
Brian R. Bondy describes why select() is limited to 64 in some os, and how to check it.
There was mentioned about "Input/output completion port (IOCP)" but its Windows NT solution.

Sorry forgot about some details:
For each selector we have timeout: 0.01
In second case all sockets are in non-blocking code (blocking mode would be suicide )

I forgot becouse I have no idea how can i handle multiple clients in case where they send data only if they need and server have other things to do than just waiting for clients. Another thing is that I can't use threads.

Network / Question about selector speed.

Does anyone knows how selector works?
Lets say that our selector can handle 64 sockets, and we have 640 connections to handle. So we have 10 selectors, 64 sockets for each and we check each selector for ready sockets.
Is that faster than iterating through simple socket array (or container)?

In http://www.sfml-dev.org/forum/viewtopic.php?t=1977&highlight=selector

Actually, the number of sockets that a selector can hold is OS-dependent. And it may perfectly be as low as 64.

How do i know how much sockets selector can handle in system that program is running?

If You're using 1.6 connect looks like this:
m_TcpSocket.Connect(m_Port, m_IpAddressHost)

Your connect returns anything? (sf::Socket::Disconnected, sf::Socket::Error)

Thanks
Wasted half a day to do the impossible, I should ask earlier.  :oops:

Edit:
How can I check count of socket that selector contains?
Edit2:
How can I check if selector contains given socket?

Hi,
I cant get std::map to work with selector

Heres server code:
http://www.copypastecode.com/31020/
Client code:
http://www.copypastecode.com/31024/
(for tests just std::cin before disconnect to prevent client from disconnection and packet sending can be deleted)

Now my problem:
Lets say we connect 100 clients TC (connMap.size()) will be 100 after closing all clients TC will be 37 and it should be 0. Whats going on?

It looks like the selector dont execute the disconnection part for sockets connected after 63.

General / [SOLVED] SFML 1.6 static library errors

Ive removed the old one from C::B and extracted the new in to the same directory.
After that in C::B compiler options check C++ compiler and linker for dynamic libs, both should be set to "mingw32-g++.exe".
