This so multiple parallel requests can be handled properly.
JSON-RPC over websockets is unchanged, as every JSON-RPC
requests goes into its own websocket frame there (easy).
This will communicate the original issuer of a command.
For example an "SAMODE #test +s" results in a SAMODE coming from
:maintest.test.net MODE ....etc....
And with this feature, we will communicate the IRCOp who did it:
@unrealircd.org/issued-by=OPER:Syzop..etc....
This tag is only sent to servers and to IRCOps, not to ordinary users.
The plan is to support the following variants:
Services: unrealircd.org/issued-by=SERVICES:NickServ@services.test.net
IRCOp: unrealircd.org/issued-by=OPER:Syzop@maintest.test.net:Operblock_name
JSON-RPC: unrealircd.org/issued-by=RPC:adminpanel@irc1.test.net:Adminpanel_Actual_User
This first commit only adds SERVICES and OPER in the handlers of the
SVSNICK and SAMODE commands. The JSON-RPC variant and all of the other
commands have not been done yet.
See release notes:
+* The RPC modules are enabled by default now. This so remote RPC works
+ from other IRC servers for calls like `modules.list`. The default
+ configuration does not enable the webserver nor does it cause
+ listening on any socket for RPC, for that you need to follow the
+ [JSON-RPC](https://www.unrealircd.org/docs/JSON-RPC) instructions.

if the join flood is caused by >75% of "unknown-users". This
to see if that will take care of the flood without harming
the "known-users" group. And naturally, do something similar
for message floods and nick floods.
If the flood persists, because they are caused by known-users,
then the +i/+m/etc actions are still taken.
This is work in progress, and some things are set to useful-
for-testing values, such as an unsettime of 1 minute.
This was a counting bug in src/socket.c. The socket itself was actually
freed though, so it's purely counting that was wrong.
There could still be counting bugs elsewhere, it's always hard to get
this right, for 20 years already :D
This was previously tried at 19-apr-2020 in bc70882bd3
in UnrealIRCd 5.0.5. Sadly it had to be reverted immediately with a quick 5.0.5.1
release, all because of a PCRE2 100% CPU usage. Since then that bug has been fixed,
plus another bug. I'm now readding it "as an option" that is marked experimental.
Hopefully people test it out and can report back if it works well and then we can
make it the default someday.
This makes it a runtime setting so makes it much easier to switch back/forth if
there are any issues without recompiling anything. Had to use a bit more code now
though to handle the recompiling of spamfilters if the setting is changed.
Original issue was https://bugs.unrealircd.org/view.php?id=5187
* [Spamfilter](https://www.unrealircd.org/docs/Spamfilter) can be made UTF8-aware.
* This is experimental, to enable: `set { spamfilter { utf8 yes; } }``
* Case insensitive matches will then work better. For example, with extended
Latin, a spamfilter on `ę` then also matches `Ę`.
* Other PCRE2 features such as [\p](https://www.pcre.org/current/doc/html/pcre2syntax.html#SEC5)
can then be used. For example you can then set a spamfilter with the regex
`\p{Arabic}` to block all Arabic script.
Please do use these new tools with care. Blocking an entire language
or script is quite a drastic measure.
* As a consequence of this we require PCRE2 10.36 or newer. If your system
PCRE2 is older than this will mean the UnrealIRCd-shipped-library version
will be compiled and `./Config` may take a little longer than usual.
RPC clients with the RPC user and such.
Most of this work is for server.rehash which causes the request to
be saved, then a rehash begins, and a few seconds later (or whenever)
the entire rehash log and success/failure is indicated in the
JSON-RPC response.
TODO: all documentation for this
socket listening in data/rpc.socket, because why not... only the
ircd user has access to it by default (well, and root).
Don't add the external listener HTTP(S) port by default though,
because not everyone may want that exposed to the outside world.
The default creation of data/rpc.socket can be prevented by a
@define $NO_DEFAULT_RPC_SOCKET "1"
