6b13806066 Fix getting servers from and being listed on id's q3 master server
Use q3 master protocol when com_gamename is Quake3Arena (the default), otherwise use dpmaster protocol.

ba385fa43c - Switch master server protocol to dpmaster for better game separation. Based partly on patch by Zack Middleton
- Get rid of ugly cvars sv_heartbeat and cl_gamename and replace with single com_gamename
- Remove sv_flatline. Flatlines are ignored by dpmaster and are considered to be insecure because flatlines can be udp-spoofed.

ac30d86db0 - Improve snapshot rate and data rate control
- Make server send packet fragments and queued packets when server is idle
- Voip protocol detection is tied to com_protocol making past-end-of-message reading unncessary
- Use Hunk_AllocateTempMemory() for buffering VOIP packets and fix buffering scheme that ryan hates so much
- Disable packet scrambling for new protocol as it is useless now
- Get rid of the old packet scrambling functions predating latest point release
- Use Hunk_AllocateTempMemory() for netchan packet queue to fix memory leak when client gets disconnected with packets in the queue
- Use Hunk_AllocateTempMemory() for download blocks to fix memory leak when client gets disconnected with download blocks in the queue
- Fix SV_RateMsec to account for udp/udp6 packet lengths

  * bans can now be deleted by giving address ranges, too.

5d63a38ad9 Basic IPv6 support. Some inspiration from the patches by Lubos Dolezel and JF Tremblay at https://bugzilla.icculus.org/show_bug.cgi?id=2355. 2008-04-04 23:22:22 +00:00

e46fe24426 * rewrite of the win32 dedicated console:
1) NET_Sleep() no longer watches for input, Sys_Sleep() added for waiting
     on input.
  2) Added "CtrlHandler" for trapping Ctrl-C and other quit methods not
     handled by signals on windows
  3) Added history support
  4) Added tab completion
  5) Removed automatic cursor/scroll adjustment (too problematic)
  6) Enable mousewheel scrolling
  7) Stop using the InputBuffer for editing

  This seems to work pretty well now, but I jumped the gun on a previous
  commit message by saying you can scroll now without locking up your server.
  That was only true up until the point that a server tried to print to
  the console, at that point it will hang until you release the scroll bar :(
  It may be possible to get around this by using a seperate thread for
  console output, but that's a whole new can of worms.

7d13d6cd3b * (bug 3066) rcon rate-limiting was not compatible with the eventual
integer overflow in Com_Milliseconds() (R1CH)
2007-05-10 01:39:58 +00:00
Tony J. White =
189e8b33f3 * (bug 2784) help to prevent reliable command overflow in cases when a slow
client is loading the map on a busy server. Specifically, hold back all
  configstring update commands while the client is CS_PRIMED.  Once the
  client goes from CS_PRIMED to CS_ACTIVE, send the cleint commands for
  updating each of the configstring indexes which were updated while the 
  client was CS_PRIMED.
