Network / SocketTCP::IsValid() not working?

« on: April 12, 2011, 08:02:16 am »

Source code can be found here: https://gitorious.org/plasma-game/plasmaserv/trees/master/src

Do you really expect us to browse your entire project to find what's wrong?

A complete (compilable and executable) and minimal source code that reproduces the problem would be much more helpful.

I would had produced a example if I could, but I couldn't reproduce it in the testing I was going, mainly cause it wasn't a bug... it was a feature  :roll:

Actually, I found the issue, it was gdb, it wasn't a crash at all... gdb apparently stops on any signal sent by the OS.  Typing "continue" works, but I wish I knew how to turn this off.

I get this backtrace:

Code: [Select]

Program received signal SIGPIPE, Broken pipe.

When I close my client.  When I try to send the next packet it crashes, even if I perform a SocketTCP::IsValid() check... it wasn't doing this earlier and I have no idea what I changed to make it not work...

Network / Max Packet Size?

« on: April 08, 2011, 08:51:52 pm »

Hmmm looking at the sf::Packet code, it checks for that a string length is shorter or equal to remaining amount of packet.   So I guess this is safe.  The only real issue I could see is infact sending a bogus packet length

Well... a lot of the security would be input validation after sf::Packet.  But you could probably do some pretty nasty things though the sf::Packet layer.   For example what if you sent a normal size packet that was to read as a string, but for the string length exceeded the end of the packet?

Is there a way we can block sending packets of certain sizes.  Since the sf::Packet uses a int32 size header, it can support packets upto 4gigs... but I don't want this to lead to abuse of my server's bandwidth and memory, and such.

Network / HTTP / FTP download status

Not yet, but it's planned for SFML 2.x.

Any ETA on SFML 2.0?

I am using HTTP/FTP to get game updates, which can be quite large.  Is there a way to determine percentage done as it downloads?

Window / TextEntered vs. KeyPressed

NVM, I got it working... somehow

Window / TextEntered vs. KeyPressed

« on: March 15, 2011, 02:28:25 am »

I have a text box, when players enter text it will display.   I am having issues though as it seems that one key pressed will generate TWO events.

How can I determine which event I should listen to, and when.

Secondly, how can I flag the other events so it can be ignored further down the widget tree.
