Some servers do not support TLS, or have invalid, expired or self-signed
TLS certificates. While the right fix would be toi contact each server
owner to add support for valid TLS, supporting plaintext upstream
connections is sometimes necessary.
This adds support for the irc+insecure address scheme, which connects to
a network in plain-text over TCP.
This is preparatory work for adding other connection types to upstream
servers. The service command `network create` now accepts a scheme in
the address flag, which specifies how to connect to the upstream server.
The only supported scheme for now is ircs, which is also the default if
no scheme is specified. ircs connects to a network over a TLS TCP
connection.
When writing a PRIVMSG or NOTICE on a channel, it is very common to use
autocompletion to mention other users on that channel. When using soju
in multi-network mode, all users will have their nicked suffixed by
`/network`. This suffix should be removed before sending it upstream.
This adds support for removing all `/network` suffixes in messages sent
to a channel of that network.
Store the list of configured channels in the network data structure.
This removes the need for a database lookup and will be useful for
detached channels.
Some servers use custom IRC bots with custom commands for registering to
specific services after connection.
This adds support for setting custom raw IRC messages, that will be
sent after registering to a network.
It also adds support for a custom flag.Value type for string
slice flags (flags taking several string values).
The database is now initialized automatically on first run. The schema
version is stored in SQLite's user_version special field. Migrations are
stored in an array and applied based on the schema version.
Instead of having one ring buffer per network, each network has one ring
buffer per entity (channel or nick). This allows history to be more
fair: if there's a lot of activity in a channel, it won't prune activity
in other channels.
We now track history sequence numbers per client and per network in
networkHistory. The overall list of offline clients is still tracked in
network.offlineClients.
When all clients have received history, the ring buffer can be released.
In the future, we should get rid of too-old offline clients to avoid
having to maintain history for them forever. We should also add a
per-user limit on the number of ring buffers.
