is 2.13 or newer, as this requires jansson_version_str().
And no, we don't use macro's (eg JANSSON_MAJOR_VERSION). We never do that for
any of the displayed library versions (OpenSSL, libsodium, c-ares, curl, etc)
as macro's only reflect the compile-time library version and not runtime,
and thus are misleading... which can be especially problematic in case of a
security issue. So good that jansson added this function.
This is start_of_normal_client_handshake() by default, but is
start_of_control_client_handshake() for the control channel
(for './unrealircd rehash' and such). Previously that was hardcoded.
It is also used by the RPC code now.
Things like setting the client->status to CLIENT_STATUS_CONTROL
and list_add(&client->lclient_node, &control_list);
This does mean that we now add clients earlier to the unknown list,
even ones that are going to be control sockets and clients that are
going to be z-lined etc, but it should be a minimal performance hit
since it are just 1-4 insertions in a circular list.
At the same time it makes the code more cleaner and more maintainable
especially with all the "special cases" and such that are there now
and will only become more and more...
including version, description, author, flags. The output is
pretty much identical to "MODULE -all" on IRC as IRCOp.
Useful for the future if you want to verify a module has been
upgraded from the command line.
"./unrealircd reloadtls" and there is now also a "./unrealircd status"
The output is colorized if the terminal supports it (just like on the
boot screen) and also the exit status is 0 for success and non-0 for
failure. The purpose of all this is that you can easily detect rehash
errors on the command line.
These three commands communicate to UnrealIRCd via the new control
UNIX socket, which is in ~/data/unrealircd.ctl.
This also does a lot of other stuff because we now have an internal
tool called bin/unrealircdctl which is called by ./unrealircd for
some of the commands to communicate to the unrealircd.ctl socket.
Later on more of the existing functionality may be moved to that
tool and we may also provide it on Windows in CLI mode so people
have more of the same functionality as on *NIX.
