RFC 2812 states that the SQUIT command is available to (IRC) operators, but when any client (IRCop or not) issues an SQUIT command, ngIRCd replies with ERR_NOTREGISTERED, which is not permitted by the RFC.
Also, quoting from RFC 2812:
The INFO command is REQUIRED to return information describing the server: its version, when it was compiled, the patchlevel, when it was started, and any other miscellaneous information which may be considered to be relevant.
Implementing the SUMMON command is not required, but:
If summon is not enabled in a server, it MUST return the ERR_SUMMONDISABLED numeric.
Likewise for the USERS command:
If disabled, the correct numeric MUST be returned to indicate this.
The patch below adds a test (called misc-test for lack of a better name) for these commands and modifies:
* testsuite/Makefile.am to run misc-test; * parse.c and irc-server.c to make IRC_SQUIT handle client requests; and * parse.c and irc-info.{h,c} to reply to INFO, SUMMON, and USERS.
It is perhaps worth noting the commands SERVICE, SERVLIST, and SQUERY, which remain unimplemented, are described in RFC 2812 section 3, which also states that "All commands described in this section MUST be implemented by any server for this protocol."
