mr_server: Handle unknown error codes
As mr_server is a module, it could potentially receive an unknown
error code from check_server().

78946542bb modules: move module loading/unloading commands to dedicated module.
There's no reason to really have these in the main ircd anymore, static
modules are dead and aren't coming back.

To ensure people don't do something hopelessly retarded, this is a core
module.

3c7d6fcce7 Message handlers should return void.
Also fix up some return values and stuff to use bool (or void if
nothing). I just did it whilst I was here.

According to jilles, the return value used to signify whether or not the
client had exited. This was error-prone and was fixed a long, long time
ago, but the return value was left int for historical reasons.

Since the return type is not used (and has no clear use case anyway),
it's safe to just get rid of it.

07554369bd Detect stdbool.h and add conformant shims if it isn't available
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.

63eb8567cb implement configurable channel modes (closes #31)
While functionally compatible with the implementation in ElementalIRCd, our approach is different,
specifically pre-calculating the bitmask at config load time.  This is more efficient, and allows us
to report errors as part of the configuration phase.

8db50c03e6 BAN: Don't schedule check_klines for 0 seconds in the future.
When receiving bans from a bursting server, if kline_delay is set to 0
(the default), rb_event_addonce will be called to schedule an event for
0 seconds in the future. While this works fine for the fallback
rb_event_run function, the epoll implementation ends up scheduling a
timerfd for the event in the past, which is then never executed.

While fixing this, I also made rb_event_add and rb_event_addonce reject
attempts to add events scheduled for 0 seconds in the future; they're
instead rewritten to run 1 second in the future.

77d3d2dbaf Remove s_assert definition from ircd_defs.h and add it to its own header.
s_assert requires some higher-level functionality that shouldn't be
present in ircd_defs.h. ircd_defs.h is used by ssld, which has no notion
of logging or sending IRC messages. Additionally, some of the headers
s_assert depends on result in conflicting definitions in ssld.c.

This change also fixes the compile when using --enable-assert=soft.

numeric is passed through from other code to be sent to a client. Fix it
by porting more code from ircd-ratbox 3.1.

ca4c2a86ee Add support for hookifying PRIVMSG/NOTICE.
This will allow us to modularize message processing, e.g. having new modules to manipulate
channel and private messages in new ways.

Yes: it can be used to intercept messages, but such modules are already out in the wild for
charybdis anyway -- so this doesn't really change anything there.

If you are changing the text, then it is your responsibility to provide a pointer to a new
buffer.  This buffer should be statically allocated and stored in your module's BSS segment.
We will not, and cannot, free your buffer in core, so dynamically allocated buffers will
cause a memory leak.

This will allow us to simplify m_message considerably, by moving channel mode logic out to
their own modules.

d1316b193b Keep forward channels in sync after a netjoin.
Arbitrarily prefer a forward channel to no forward channel and an
alphabetically higher forward channel to a lower one.

This is a simplistic implementation that generates one MODE message to
local clients for each ban removed (to be replaced).

For simplicity and to avoid amplification of incoming MODE messages,
regular modes may still desync the forward channel of a ban.

b583faf970 Add support for customizing the usable nick length.
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.

7eec45bc9d Back out chanroles.
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.
2011-07-07 21:24:14 -04:00
Elizabeth Jennifer Myers
8aabb973c0 Implement chanroles, as discussed with nenolod.
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.

a1574df4a2 Allow kick_on_split_riding to protect channels with mlocked keys.
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).
