irctest.server_tests.connection_registration

Two users register simultaneously with the same nick.

Syntax: "<client> <command> :Not enough parameters" -- https://defs.ircdocs.horse/defs/numerics.html#err-needmoreparams-461 -- https://modern.ircdocs.horse/#errneedmoreparams-461

Use of this numeric: "The minimum length of <username> is 1, ie. it MUST not be empty. If it is empty, the server SHOULD reject the command with ERR_NEEDMOREPARAMS (even an empty parameter is provided)" https://github.com/ircdocs/modern-irc/issues/85

A user connects and requests the same nickname as an already

registered user.

“The server must close the connection to a client which sends a

QUIT message.” -- <https://tools.ietf.org/html/rfc1459#section-4.1.3>

“A client session is terminated with a quit message. The server

acknowledges this by sending an ERROR message to the client.” -- <https://tools.ietf.org/html/rfc2812#section-3.1.7>

“The password can and must be set before any attempt to register

the connection is made.” -- <https://tools.ietf.org/html/rfc1459#section-4.1.1>

“The optional password can and MUST be set before any attempt to register the connection is made. Currently this requires that user send a PASS command before sending the NICK/USER combination.” -- <https://tools.ietf.org/html/rfc2812#section-3.1.1>

"If the password supplied does not match the password expected by the server, then the server SHOULD send ERR_PASSWDMISMATCH and MUST close the connection with ERROR." -- https://github.com/ircdocs/modern-irc/pull/172
