This adds a new ISUPPORT token, NICKLEN_USABLE which is strictly an informative value.
NICKLEN is always the maximum runtime NICKLEN supported by the IRCd, as other servers may
have their own usable NICKLEN settings. As NICKLEN_USABLE is strictly informative, and
NICKLEN is always the maximum possible NICKLEN, any clients which depend on NICKLEN for
memory preallocation will be unaffected by runtime changes to NICKLEN_USABLE.
The default NICKLEN is 50; the default serverinfo::nicklen in the config file is set to
30, which is the NICKLEN presently used on StaticBox.
This used to be only advertised if a service was linked, which made
sense in ratbox when +r was only settable if services were available.
Now, however, +r is always available and so should always be advertised.
After a configuration change (or deoper with no_oper_flood) sent_parsed
might be way higher than allow_read, so that the user would have to wait
a long time before the server responds. Avoid this.
They are now in messages, even if client_flood_message_time is not 1.
If client_flood_message_time is not 1 (by default it is), this needs a
configuration change to maintain the same behaviour.
* Deduce allow_read from the client's state (IsFloodDone) rather than
storing it in LocalUser.
* Fix the documentation (in oper /info), however strange
client_flood_burst_rate and client_flood_burst_max may seem, that is
how they currently work.
After setting up signal handlers, unmask the signals we care about
(installed handlers for).
When handling SIGINT, the kernel adds SIGHUP and SIGINT to the signal
mask (as requested in sigaction()); if execve() is called from the
signal handler, this change is persistent.
nenolod gave the thumbs-up to port ircd-seven banfowards to charybdis to spb
for a while, and people have asked about it. Might as well do it since it's a
slow weekend.
Note that as a side effect use_forward is removed from the config and
unconditionally enabled!
I meant to do this 3 years ago when I rewrote the cloaking modules. I
never got around to it. Now I am. :p
Also add some basic comment headers whilst I'm here.
While what chanroles are trying to accomplish is a good idea, it is
apparently unclear this is the proper way to do it. Until we figure out
the exact way we wish to do this, it should be reverted for now.
