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.
As jilles pointed out, it is best that the chanserv access list always
remain synced with the grant list. Thus, the ability for clients to set
this is not a good idea unless services knows about the grant, but this
leads to all sorts of messy issues and likely isn't worth it.
this makes setting new roles on a user much easier as we're just setting the roles they
should be having, instead of having to try to revoke roles we don't necessarily know
about.
The theory behind this is that services sends an ENCAP * GRANT #channel
UID :+flagspec message specifying the chanroles the user has. They are
mapped into flag bits and applied to the membership of the user. They
then are restricted or permitted to what they can do based on the
permissions mask regardless of rank.
For backwards compatibility, the default permission bit (without a GRANT
statement) allows a user to to anything an existing op can do ONLY if
they are an op.
Todo: make CHANROLE_STATUS work (the ability to apply +ov to people),
which is at the moment controlled by CHANROLE_MODE.
When we broadcast a KILL message, this generates server notices on all
other servers (assuming the target user exists). Therefore, we should
also send a notice to our local opers.
Do kick_on_split_riding if services sends an SJOIN
with a lower TS and a different key. This relies on
services restoring TS (changets option in atheme) and
services not immediately parting after receiving the
KICK, which is the case in recent atheme.
For invite-only channels, still only do
kick_on_split_riding in netbursts. Services is
assumed to handle this itself (atheme does).
