[edit] Features

IRC server features, mostly extensions to RFC 1459. Probably also implementations of RFC 2810, RFC 2811, RFC 2812, RFC 2813, and possibly IRCX.

  • +channels (In early IRCds, these were simply named channels. At least one modern IRCd (IRCD) uses the + prefix for modeless channels, ie no chanops and channel mode forced to +nt. This is described in RFC 2811.)
  • #channels ("+channels" were later replaced with "#channels" in version 2.7, numeric channels were removed entirely and channel bans (mode +b) were implemented.)
  • &channels (irc2.8, those that exist only on the current server, rather than the entire network)
  •  !channels (irc2.10, those that are theoretically safe from suffering from the many ways that a user could exploit a channel by "riding a netsplit"; IRCds using timestamping provide (most of) this functionality on #channels)
  •  %#channels (#channels whose name are in UTF-8 for IRCX)
  •  %&channels (&channels whose name are in UTF-8 for IRCX)
  •  %!channels (!channels whose name are in UTF-8 for IRCX)

[edit] Notes

  1. ^ epoll (Linux since 2.6) - I/O event notification facility. Has a much better performance than select() and poll() system calls.
  2. ^ kqueue (FreeBSD since 4.1) - asynchronous event dispatch mechanism.
  3. ^ "POSIX.4 Real Time Signals" (Linux since 2.4) - special class of Linux system signals used for notification of events on file descriptors. Deprecated in favour of epoll.
  4. ^ The ability for network staff (not channel ops, but ircd opers) to be denoted in a channel with a special prefix
  5. ^ Protect "higher" opers from being killed and/or z, k, or g-lined by "lower" opers
