Revision 1.121 - (show annotations) (download) (as text)
Fri Sep 20 02:06:25 2002 UTC (17 years ago) by stdarg
Branch: MAIN
Changes since 1.120: +5 -4 lines
File MIME type: text/x-chdr
* Moved several things from the core into libegg
* Server module uses new network code
* Lots of stuff removed from the server module, like flood stuff, which should go into a new module
* Moved some things from irc module to server module (mostly bind stuff, like pub)
* Not everything works right now, but I wanted to get it into cvs in case my computer dies a horrible death. I'm going to combine irc/server (mostly) and make a new one for all the default protection stuff.
* Right now server messages are not queued. I thought the code was pretty much beyond repair. The new queueing code will hopefully be more maintainable.
* I'm not sure I added/removed all the files necessary! Let me know if it doesn't compile for you.
