This avoids annoying users when someone links a test
server with the wrong nicklen and is more likely to lead
to the inconsistency being fixed than a kill.
This way, the information remains valid after a split.
For clients on TS5 servers, the nick is used; this is
not much of a problem because these are on pseudoservers
and not assumed to change nick much at all.
- the number of messages blocked by target change on
this server since it was started
- the number of IPs currently subject to a a lower
target limit on this server (these expire over time)
This check sometimes blocks oper overrides (OMODE).
It does not stop any hacks that the channelTS check
already stops, because CHFL_DEOPPED is only set when
this server ignored an @ in an incoming SJOIN (the
SJOIN is then propagated without the @) and this
can only be because of a TS difference.
- Do not use hide_error_messages for certain "safe" ERRORs.
- If hide_error_messages hides an ERROR from a handshake,
send a server notice anyway, but without the message
text.
- Send server notices about ERRORs from handshakes network
wide if it was a remote connect.
This changes flattened /links output to disclose less
routing information and slightly increases memory "leak"
from server names that do not come back anymore.
If we are connecting outward to a server, check if the
server name they sent is the same as what we tried to
connect to. Previously such a connection could succeed
if there existed connect blocks with the same IP and
passwords for the other server name.
Another handling of SJOINs without nicks:
Propagate them if the channel is +P or the channel
already existed, otherwise remove the channel again
and do not propagate the SJOIN.
Change TS6 JOIN processing
- don't send out simple modes in TS6 JOIN and TS5 SJOIN when
a local user joins an existing channel
- don't send out simple modes in TS6 JOIN and TS5 SJOIN when
propagating a TS6 JOIN
- don't interpret simple modes in an incoming TS6 JOIN
This is to avoid desyncs when certain mode changes (e.g. -im)
cross with joins. A downside is that simple modes will be
more desynched when a JOIN creates a channel or lowers TS,
but that's less important.
Update the TS6 specification to include this, and clarify
that TMODE can come from a server and that MODE must be
translated into TMODE from other servers too.
