Links that are 'no-export' are not distributed to the rest of the IRC network (including local peers).
This provides a core primitive for 'anycasting' services (but the actual issue of synchronizing data in
a services package is left to the authors of the services package).
Don't use the librb callback type as we're always passing client_p.
Provide a return value so that the connect handler can exit_client()
and the accept handler can opt to use the default dead handler.
Fix the server connection configuration so that it can simultaneously
handle a hostname/IPv4/IPv6 for connecting and a hostname/IPv4/IPv6
for binding. Maintains backwards compatibility for matching a hostname
with a mask.
Multiple host/vhost entries can be specified and the last value for
each address family is stored. Hostnames that resolve automatically
overwrite the IP address.
Server connections can now be made to either IPv4 or IPv6 at random
as well as preferring a specific address family.
This also lays the groundwork for the netjoin batch type, but that isn't
implemented yet. I don't like how some of this is implemented but it'll
have to do for now...
Compile tested, needs more testing.
now connid's are allocated on demand and clients may have as many connid's as necessary.
this allows us to build chains of helpers while ensuring the ircd properly tracks and GCs the resources.
Charybdis requires C99 already, so it's high time we start using
stdbool. I've converted a few pieces of code already.
A lot of the old code that uses YES/NO should probably be updated too
because that's fucking hideous.
It's possible for which_ssld to fail and return NULL, handle this in
start_ssld_connect and start_ssld_accept by returning NULL. The NULL
return value is already handled in all calls to start_ssld_accept,
so handle this for start_ssld_connect by reporting an error connecting.
Handle it in start_zlib_session by exiting the client.
