- For HOOKTYPE_LOCAL_JOIN and HOOKTYPE_REMOTE_JOIN: drop parv[] argument
as it was useless anyway, it only contained the channel name in parv[1]
but never the key, sometimes was entirely NULL even.
- For HOOKTYPE_PRE_LOCAL_JOIN instead of char *parv[] we now pass
const char *key. As predicted more than a year ago when fixing
0902ed7a99
* channel->mode.extmode to channel->mode.mode
* channel->mode.extmodeparams to channel->mode.mode_params
This because all channel modes that are set there are extended channel
modes, only lists are still in core atm and they never get set here.
which BANCHK_* events you want to listen, eg BANCHK_JOIN, BANCHK_MSG.
You can use BANCHK_ALL to watch on all events.
Only BANCHK_TKL is not included there and needs an explicit
BANCHK_ALL|BANCHK_TKL.
The caller will now take care of BANCHK_* filtering so we won't
waste any CPU on calling an is_banned() function that isn't
interested at all in the event that we have.
Also, no longer require an extban->is_banned function, since some
extbans don't use it. This too saves useless calls.
Currently only supported option is:
BCTX_CONV_OPTION_WRITE_LETTER_BANS: always write letter bans
This removes the NULL pointer magic that i was not happy about.
server to server traffic to be letter extbans.
Yeah this is a tad ugly, but the alternative was worse, see
header of the file for the full story.
Module is loaded by default (obviously).
Still to do: only do this for non-U6 servers (add some PROTOCTL)
And probably alter clean_ban_mask because I don't like the
magic on NULL client at the moment.
The .conv_param() now receives the ban minus the ~own-extban.
And it should also return the part minus the ~own-extban.
Changes to findmod_by_bantype():
1) Takes a string now, rather than a single char value,
so it is ready for named extbans.
2) Second parameter added so you can easily jump to the remainder.
Eg:
extban = findmod_by_bantype(b->banstr, &nextbanstr);
[..check if extban is non-NULL and then..]
b->banstr = nextbanstr;
This because "can send" is ambigious and could be interpreted to
mean that the client may send this mtag to us, while in fact this
function decided whether to send TO the client.
Just as a reminder: don't blindly assume that if anything is set here
that the user is logged in, there is IsLoggedIn(client) for that.
Reason: if the account name starts with a digit or is "*" then the
user isn't actually logged in ;)
change some more calls to make_channel() to use find_channel().
Also make it take 1 argument instead of 3.
Needed to be careful in sjoin code since the previous code set
channel->creationtime to 0 if client was a remote. Now merged
a few if's into one. Should be correct :D.
This will likely reduce performance, but this should not matter in modern times.
Also added flags to let modules know which one the entry belongs to, and what
to do with it.
Now modules should be able to add their own WATCH methods (like IRCv3 MONITOR),
or extend functionality to notify about other changes than the default log on,
log off and away statuses (like SETNAMEs).
This broke SASL services autodetection and also sasl=x,y,z in CAP.

Of course the easiest solution would be just to set .remote_write=1
for this, which is what I've just done for the 5.2.1.1 release.
But there seems to be a pattern here. When a server wants to write
its own object (irc1.example.net writing to the MD object of
irc1.example.net) we have the problem that that object is both
"our client" and from the other server POV it is "themselves".
On one hand you may want to allow that (eg for 'saslmechlist'), on
the other hand a server writing its own 'certfp' sounds like a bad
idea in principle.
So we now add a new option for the 'self' case and make some MD
objects use it. In fact, in the core we now have zero MD objects
using remote_write. We keep the option available though, for example
for k4be's geoip modules and possibly future features.
Module API change:
* .self_write added which allows a server to write to its own object
(irc1.example.net writing to the MD object of irc1.example.net)
* .remote_write still exists too if you want to allow remote servers
to write to your own objects
* Note that in all cases, servers can always write to their own
(child) client objects.
Changes:
* The link-security MD changed from .remote_write=1 to .self_write=1
* The salmechslist MD now has .self_write=1, this fixes the actual bug
Modules can still opt-in via mreq.remote_write=1 to allow it for
certain moddata.
For example, k4be may want to do this for his geoip-base module which
allows a single server to set moddata "geoip" for all connecting clients,
including remote clients.
If you are a moddata provider then you can enable it like this:
ModDataInfo mreq;
[..]
#if UNREAL_VERSION_TIME >= 202125
mreq.remote_write = 1;
#endif
