Hi guys!
So I'm experimenting with the 4.2 beta release. Running a server on my dedicated box etc.

First question, is any of the source code for the server binary open to the public? I am assuming not.

Another observation, I am able to use the 4.1-style dedicated server binaries with 4.2 with only one small modification. I upped the protocol version (a constant defined in a header file) from 68 to 70 since that's what the clients are expecting now. It magically works! I'm actually surprised it works since I assume a newer protocol means new way of passing information back and forth. But so far no problems. Since I have a few "addons" and "bugfixes" in my old 4.1-style dedicated binaries it would be nice to either get the 4.2 dedicated binary source code (probably a "no") or know that the 4.1-style dedicated binaries will work after the protocol up.

The only fiddly bit that I experienced in setting up a server was an overflow in the server userinfo string, that stores all the server settings for purposes of the "getinfo" and "getstatus" queries. Since the new auth server cvars take up space in the server userinfo string, there is less space available now. So I had to fiddle with shortening some of the strings such as download server, team names, and other things to make it fit. At least I had this problem with my 4.1-style dedicated binary but I'm pretty sure the userinfo constraint hasn't changed with 4.2, unless I'm wrong.

I'm glad that Frozen Sand has decided to make incremental improvements to UrT. Thank you!

OK thanks to Nitro I managed to find this:

https://github.com/B...banTerror-4.git

I assume this is the "official" code to generate Quake3-UrT-Ded.i386.

Could someone please tell me which ioquake3 this is based off of?
Is this just a continuation of the UrT-4.1 code, i.e. ioUrbanTerrorSource_2007_12_20.zip (revision 1240 of ioquake3 plus UrT-specific changes), or was a new version of ioquake3 adopted as the base?

Rambetter,

IIRC they originally were using the latest ioquake3. Barbatos had a client that started against upstream ioquake3. I made a number of comments about how to improve it. Then suddenly that client was removed from github and they started working on this old 2007 code again. So yes, this is a continuation on ioUrbanTerrorSource_2007_12_20 (aka SVN r1142 + misc patches from later SVN revisions). You can verify this because Barbatos included the .svn/ metadata in a git repository...

You may want to review the 4.2 code before running the binary. The auth code allows for arbitrary command execution via system() calls. This is not sanitized or checked in any manner. They expose this as an ioquake3 syscall so the QVM can call it.

Grep for Sys_StartProcess.

https://github.com/B...in32/win_main.c
https://github.com/B...erver/sv_game.c
https://github.com/B.../client/cl_ui.c

Edit: Looks like they are going to move to the latest ioquake3. Yay! Hopefully they remove Sys_StartProcess in the process of moving to the latest ioquake3.
