|
The account-notify client capability allows a client to be notified
|
|
when another client's accountname changes. This capability MUST be
|
|
referred to as 'account-notify' at capability negotiation time.
|
|
|
|
When enabled, clients will get the ACCOUNT message to designate the
|
|
accountname changes for clients on common channels with them.
|
|
|
|
The ACCOUNT message is one of the following:
|
|
|
|
:nick!user@host ACCOUNT accountname
|
|
|
|
This message represents that the user identified by nick!user@host has
|
|
logged into a new account. The last parameter is the display name of
|
|
that account.
|
|
|
|
:nick!user@host ACCOUNT *
|
|
|
|
This message represents that the user identified by nick!user@host has
|
|
logged out of their account. As the last parameter is an asterisk, this
|
|
means that an asterisk is not a valid account name (which it is not in P10
|
|
or TS6 or ESVID).
|
|
|
|
In order to take full advantage of the ACCOUNT message, WHOX must be
|
|
supported by the ircd. In this case, the appropriate strategy to ensuring
|
|
you always have the accountname to display is to do the following:
|
|
|
|
1) Enable the account-notify capability at capability negotiation time during
|
|
the login handshake.
|
|
|
|
2) When joining a channel, query the channel using WHO and ensure that you
|
|
include the 'a' format token in your WHOX token request. When you get
|
|
a reply, do appropriate caching.
|
|
|
|
3) If the extended-join capability is available, enable it at client capability
|
|
negotiation time during the login handshake, and then set the accountname
|
|
based on what is sent in the extended JOIN command.
|
|
|
|
Otherwise, if extended-join is unavailable:
|
|
When new users join a channel that your client does not know the accountname
|
|
for yet, do a WHO query against that client, again including the 'a' format
|
|
token in your WHOX token request field. When you get a reply, do appropriate
|
|
caching.
|
|
|
|
4) In the event of a netsplit, the client should query the channel again using
|
|
WHO with the 'a' format token in the WHOX request field.
|
|
|
|
5) When the client receives an ACCOUNT message, update the accountname for the
|
|
client in question in your accountname cache.
