will not be called. This is used, for example, by m_cap when the CAP LS
handshake is still in progress. Modules can add their own requirements
as they see fit.
Note that, as for (CAP) functionality, this adds nothing new, it just
implements it in a cleaner way, rather than all over the place,
like in UnrealIRCd 4.x.
and has various outstanding crash and 100% CPU issues.
We have been encouraging the PCRE2 engine since the start of
UnrealIRCd 4 already.
TRE is being phased out of U4 by the end of the year, so we can
safely remove it in U5 already.
Such a variable suggests that we will never read past that, but that
is not the case, since we (correctly) assume that the buffer is
NUL terminated, which is ensured by dbuf_getmsg().
The 'length' is still available for informational purposes, to avoid
strlen()'s at various places.
Hm, I guess length can cause the same confusion as bufend, but still..
I like it better :D
Early commit, still cleaning up to do.
But what works is:
$define SERVER "hub.example.org"
$if SERVER == "hub.example.org"
link .... {
....
}
$endif
$if defined(SERVER)
....
$endif
And also we have mod-loaded() which even works half-way in a block
such as in helpop:
help Chmodes {
[..]
$if module-loaded("chanmodes/stripcolor")
" c = Block messages containing mIRC color codes [o]";
$endif
$if module-loaded("chanmodes/noctcp")
" C = No CTCPs allowed in the channel [h]";
$endif
};
As said, still need to cleanups and there are some limitations.
Also the idea is to be able to use defined values in variable names/values
but that has not yet been implemented.
You now call it with a path like is_module_loaded("extbans/timedban").
This, among other reasons, so you can differentiate between modules with
the same name, such as "usermodes/noctcp" and "chanmodes/noctcp".
This also includes buffer modifications to have a larger read buffer
and IRCv3 implementations (partial or not) for:
labeled-response, msgid, server-time, batch and account-tag.
As said, it is the initial and partial implementation.
There are still various FIXME's and TODO's, the API of various
functions may still change (actually that is true for the next
months, even) and some stuff is currently in the core that will
be moved to modules.
This is mostly to guard 3rd party module writers against making
such a mistake. Up to now such a mistake would silently corrupt
memory without warning or error. That is, until you crashed :D.
usually the fast badwords system is used instead)
* Code deduplication in src/modules/{chanmodes,usermodes}/censor.c
to src/match.c -- which may be moved later again to efuncs.
* Add --without-tre:
This means USE_TRE will be enabled by default right now
but if using --without-tre it will be undef'ed. This so we
can prepare for the TRE phase-out in 2020.
* Remove include/badwords.h, put contents in include/struct.h
The new question in ./Config now defaults to 'auto' (both for new installs
and for upgrades). You can still specify a manual limit but it is no longer
recommended.
A MAXCONNECTIONS of 'auto' means - at present - that UnrealIRCd will try
to set a limit of 8192. This is quite a bump from the original 1024.
On systems where this is not possible we will simply use the highest amount
possible, such as 4096 on many systems, or 1024.
In fact, we now no longer error when MAXCONNECTIONS is higher than the
'ulimit -n' limit but will adjust ourselves to the limit.
Only if the effective limit is below 100 we will print out a fatal error
since running in such a scenario is highly discouraged.
The reason for this change is that nowadays with drone attacks we may need
to be able to handle more concurrent sockets. Also, many Linux distro's
have a default setting of unlimited or 4096 nowadays, out of the box.
For people packaging UnrealIRCd (not end-users):
The ./configure --with-fd-setsize=xx option was removed and the
optional(!!) --with-maxconnections=xx option has been added.
We recommend you NOT to pass this option. Not passing it means that
the previously mentioned 'auto' mode will be used, which is likely
best for most users.
Module coders:
Although it is unlikely you accessed the 'MAXCLIENTS' variable,
if you did, it is now called 'maxclients' (lowercase) since it is
adjusted at runtime and no longer a macro.
encouraged to use CMD_OVERRIDE_FUNC(override_xyz) rather than declaring
the function themselves. This works similar to CMD_FUNC(somecmd).
Example:
/* Forward declaration */
CMD_OVERRIDE_FUNC(override_xyz);
[..]
MOD_LOAD(somemodule)
{
CmdoverrideAdd(modinfo->module, "XYZ", override_xyz);
[..]
CMD_OVERRIDE_FUNC(override_xyz)
{
/* Do something useful here */
Previously various information was only available for directly attached
servers, since it is communicated via PROTOCTL.
Now, we will also communicate information about leafs behind us.
IRCOps can use the /SINFO command to see these server features.
Services codes don't need to do anything, or at least are not expected
to do anything. They can still receive the information and do something
with it, of course...
Read the following technical documentation for full information,
as it will outline very specific rules for using the command S2S:
https://www.unrealircd.org/docs/Server_protocol:SINFO_command
of targets accepted for a command, eg /MSG nick1,nick2,nick3,nick4 hi.
Also changed the following defaults (previously hardcoded):
* PRIVMSG from 20 to 4 targets, to counter /amsg spam
* NOTICE from 20 to 1 target, to counter /anotice spam
* KICK from 1 to 4 targets, to make it easier for channel operators
to quickly kick a large amount of spambots
See https://www.unrealircd.org/docs/Set_block#set::max-targets-per-command
(actually still need to write the documentation)
maximum number of conversations a user can have with other users at the
same time. Until now this was hardcoded at limiting /MSG and /INVITE to
20 different users in a 15 second period. The new default is 10 users,
which serves as a protection measure against spambots.
See https://www.unrealircd.org/docs/Set_block#maxcc for more details.
not picked up by any other IRCd. The 005 tokens KNOCK MAP USERIP are
now used instead. We do not announce STARTTLS in 005 anymore as this
is way too late (post-handshake, sensitive info already sent and/or
received). Not to mention STARTTLS is not the preferred method to
setup a secure connection in the first place.
Module coders: this means CommandAdd() with M_ANNOUNCE should no
longer be used. If a 3rd party module does use it, then UnrealIRCd
will now raise a warning. In a later UnrealIRCd version the flag
is likely to be removed completely so would cause a compile error.
(I doubt any module uses this anyway... but still..)
