just like client->user is set if the client is a user.
Rename client->srvptr to client->uplink: this is the uplink that the client
is connected to. If the client is a user then it is set to the server that
the client is connected to, if the client is a server then it is set to the
server that the server is connected to (the.. tadah.. uplink).
For local clients it is always set to &me.
for fake lag calculations only (well, except for 1 corner case).
As said, modules should use the new function:
void add_fake_lag(Client *client, long msec)
This was more of a oversight because the cmdbytes calculation happens
in a different function after message tags have already been processed.
Also, wasn't really important up to now since we only allow quite short
tags at the moment.
Instead of just counting these in cmdbytes, as would be the most logical
and easiest fix, we use a different strategy:
We use a separate counter for message-tags so clients benefit from the
"rounding down rule". In other words: the first xyz bytes give you
no extra penalty compared to before (eg they are "free"). Useful for
clients who use eg @label heavily.
By default this is 90 bytes for unknown-users and 180 bytes for
known-users. See lag-penalty-bytes in set::anti-flood.
This also allows known-users to execute slightly more commands per second.
For people who want their trusted users/bots to allow even more commands
per second (eg 20cmds/sec) we now have a nice FAQ item that uses this:
https://www.unrealircd.org/docs/FAQ#high-command-rate
The new target type is called 'T' and we match against "name=value"
of each message tag (or just "name" if it is without value).
Example: SPAMFILTER ADD -simple T kill 0 this_is_a_test +typing=active
(No this is not a suggestion :D)
This probably won't be used much at all, but it is good to have the
option available in case there is some massive problem,
especially since more message tags may pop up sooner or later.
Caveat: this is actually a bit slow as we may have to check multiple
message tags for a single line.
If there are zero message-tag spamfilters then we will automatically
short-circuit and save all this CPU, which will be the most common case.
The handshake delay exists so results from DNSBL's can be checked before
the user is fully online. Whenever someone is exempt from DNSBL checking
it serves no purpose, so we mark it that the user has no handshake delay.
This will speed up connecting by up to 2 seconds (by default).
Also updated WebIRC example to suggest this now:
https://www.unrealircd.org/docs/WebIRC_block#UnrealIRCd-side
just like hooks now. Yeah we've messed up a few times by now.
Seems only Gottem uses them :D
So now it would call for example: prio -10, prio 0, 10, 20, cmd.
This matches the behavior of hook priorities (and swhois etc.)
in a sending loop if you used a services logging channel.

The same bug was reported and seemingly fixed before, but wasn't
actually.
src/parse.c. Also re-order functions in parse.c so they appear in
logical order (1->2->3->4) rather than various helper functions first
and some random order.
This so I - and others - don't constantly have to wonder whether the client
is called sptr, cptr or acptr in a simple routine.

Couldn't just mass-replace of course since there are places where there
are multiple clients involved. So had to check each function.
Also renamed some 'acptr' to 'target' and such.
I will write a page with new style rules later.. but in short if there is
only 1 client involved it will now be called 'client'.
code changes in UnrealIRCd itself:
1) Clients are no longer freed directly by exit_client. Most fields
are freed, but 'sptr' itself is not, so you can use IsDead() on it.
2) exit_client now returns void rather than int
3) ALL command functions return void rather than int.
Of course this also affects do_cmd, command overrides, etc.
This is a direct consequence of the removal of 'cptr' earlier, as that
was used to signal certain things that are now no longer possible
(and it raises the question if things were always correctly signaled
in the first place, so may fix some bugs).
It also makes the code more resillient against cases where you forgot
to check if the client was freed. Still, you are encouraged to do an
IsDead(sptr) if you are calling functions that may kill clients,
such as command functions or things that may use spamfilter.
More changes will follow, such as the removal of FLUSH_BUFFER.
** Exit this IRC client, and all the dependents (users, servers) if this is a server.
* @param sptr The client to exit.
* @param recv_mtags Message tags to use as a base (if any).
* @param comment The (s)quit message
* @returns FLUSH_BUFFER is returned if a local client disconnects,
* otherwise 0 is returned. This so it can be used from
* command functions like: return exit_client(sptr, ....);
'sptr' is sufficient and in most cases the only one you should care about.
Should you need it, you can access sptr->direction in cases where you
need the old information (usually only for some sendto_* functions
and some protoctl checks), so 'cptr' was redundant too.
[!] This change likely introduces some bugs. This was many hours of work.
I only cut some corners in 4 functions, which will be fixed at a later
stage..... yes, more major changes to come.
On the plus side, I likely fixed some bugs in the process. Situations
where cptr vs sptr usage was incorrect. Eg using cptr->name (near server)
when sptr->name should be used (the actual source server), etc....
extern int strnatcmp(char const *a, char const *b);
extern int strnatcasecmp(char const *a, char const *b);
This will be handy for version comparisons. For example they will
return -1 (=lower) for things like ("1.4.9", "1.4.10"), unlike strcmp.
Also, some loosely related spelling fixes elsewhere.
This so we have a few simple concepts:
Client: this can be a user, server, or something unknown yet
Then the type of clients:
User: this is a user, someone with a nick name.
Server: this is a server
Etc.
as cptr->from is NOT (necessarily) the server where cptr is connected to.
So we now call it cptr->direction since it indicates the directly connected
server (or &me)... in other words: the direction of the client path.
aChannel to Channel, and some more. Third party module coders will
love this. But.. it makes things more logical and the doxygen output
will look more clean and logical as well.
(More changes will follow)
