Just force-set the nickname and completely disregard what the client
sets during connection registration. Clients must discover their
effective nickname via RPL_WELCOME.
Most users will connect to their server with `<username>` as their
username in order to configure their upstreams.
Multi-upstream can be unintuitive to them and should not be enabled on
that first connection that is usually used for upstream configuration.
Multi-upstream is instead a power-user feature that should be explicitly
enabled with a specific network suffix.
We reserve the network suffix `*` and use it a special case to mean that
it requests multi-upstream mode.
Currently, if we fail connecting to a new networking during welcome, we
send no error message to the client, and the connection remains open in
an undefined state.
Given the input:
NICK nick
USER user/invalid.xyz s e r
PASS pass
soju will fail to connect, add a message to its own logs, but will
return no message to the downstream.
This fixes the issue by forwarding the error message if it is an IRC
error message (which it is for connecting to new networks).
We should probably also close the connection after the message is
written, because it leaves the connection in an undefined state. This is
TODO for now because we'd have to wait for the error message to be
written out first, which is non-trivial.
On some systems (namely Windows), syscall.Rlimit is not defined, and
makes the build fail.
This fixes the build by making the rlimit calls only run on archs where
it is defined, defaulting to a stub on other systems.

Previously, when we sent READ for an upstream which was disconnected,
we would fail with an error. This is because we called unmarshalEntity,
which checked that the upstream was in the connected status.
But we don't need to be connected to update the READ timestamp, this is
a purely offline (wrt the upstream) operation.
This simply switches the call from unmarshalEntity to
unmarshalEntityNetwork to fix the issue.
When the client supports draft/chathistory, no need to request
delivery receipts via PING messages. Let's just not leave delivery
receipts alone. They'll go stale but should be never used (or used
by a non-chathistory client).
When fetching messages via draft/chathistory from a conversation
with another user, soju would send the following:
:sender PRIVMSG sender :hey
instead of
:sender PRIVMSG recipient :hey
because the file-system message store format doesn't contain the
original PRIVMSG target.
Fix this by doing some guesswork.
READ lets downstream clients share information between each other about
what messages have been read by other downstreams.
Each target/entity has an optional corresponding read receipt, which is
stored as a timestamp.
- When a downstream sends:
READ #chan timestamp=2020-01-01T01:23:45.000Z
the read receipt for that target is set to that date
- soju sends READ to downstreams:
- on JOIN, if the client uses the soju.im/read capability
- when the read receipt timestamp is set by any downstream
The read receipt date is clamped by the previous receipt date and the
current time.
