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.
Instead of always requiring users to explicitly specify the network
name, guess it from the downstream connection.
Network commands are left as-is because it's not yet clear how to
handle them.
This allows users to set a default realname used if the per-network
realname isn't set.
A new "user update" command is introduced and can be extended to edit
other user properties and other users in the future.
Rename the "sql" directive to "db". Rename the "log" directive to
"log fs".
In the future, we'll maybe support more databases and more message
stores. Make it so it's easy to integrate these new festures to the
config file format.
This adds the `channel update` service command, which is used to set the
auto-detach, auto-reattach, and message relaying settings of a channel.
Of note is that currently the parser parses `#` as a comment, which
means any `channel update #foo ...` will actually need to be escaped to
`channel update "#foo" ...`
It's too easy to setup a reverse proxy which doesn't support the PROXY
protocol, or lets the X-Forwarded-For header fields pass through.
Disable this by default.
To restore the previous behaviour, add `accept-proxy-ip localhost` to
the config file.
This allows to set the list of IPs allowed to act as a proxy. This is
only used for WebSockets right now, but will be expanded to TCP as well
once the PROXY protocol is supported.
When Unix socket support will be added for listeners, unix:// will be
ambiguous. It won't be clear whether to setup an IRC server, or some
other kind of server (e.g. identd).
unix:// is still recognized to avoid breaking existing DBs.
