Fix IRC listener relay of bodies and modes, and JOIN names ( closes #127 )
...
check / check (push) Canceled after 0s
The IRC listener relayed only the first line of a PRIVMSG or NOTICE
body; it now sends one line per body line. A MODE change reached IRC
listener members without its key, limit or mask, and "+o bob" went out
as one trailing parameter; each value is now its own parameter, in the
relay and in the echo to the IRC listener user who made the change.
CR, LF and NUL are now removed from each parameter of a line sent to an
IRC listener connection, before the leading ':' is decided, and from
the whole line, so a stored body line, key or mask cannot start a line
of its own. The channel name check moved from the HTTP handler into
service.JoinChannel, so the IRC listener's JOIN refuses the same names
with 403.
Model: opus-5-5

feat: add traditional IRC wire protocol listener ( closes #89 ) ( #94 )
...
check / check (push) Successful in 5s
## Summary
Adds a backward-compatible IRC wire protocol listener (RFC 1459/2812) that allows standard IRC clients (irssi, weechat, hexchat, etc.) to connect directly via TCP.
## Changes
### New package: `internal/ircserver/`
- **`parser.go`** — IRC wire protocol message parser and formatter
- **`server.go`** — TCP listener with Fx lifecycle integration
- **`conn.go`** — Per-connection handler with registration flow, PING/PONG, welcome burst
- **`commands.go`** — All IRC command handlers (JOIN, PART, PRIVMSG, MODE, TOPIC, KICK, WHOIS, etc.)
- **`relay.go`** — Message relay goroutine that delivers queued messages to IRC clients in wire format
### Modified files
- **`internal/config/config.go`** — Added `IRC_LISTEN_ADDR` environment variable
- **`internal/handlers/handlers.go`** — Broker is now injected via Fx (shared with IRC server)
- **`cmd/neoircd/main.go`** — Registered `broker.New`, `ircserver.New` as Fx providers
- **`pkg/irc/commands.go`** — Added `CmdUser` and `CmdInvite` constants
- **`README.md`** — Added IRC Protocol Listener documentation section
### Tests
- Parser unit tests (table-driven, round-trip verification)
- Integration tests: registration, PING/PONG, JOIN, PART, PRIVMSG (channel + DM), NICK change, duplicate nick rejection, LIST, WHOIS, QUIT, TOPIC, MODE, WHO, LUSERS, MOTD, AWAY, PASS, CAP negotiation, unknown commands, pre-registration errors
- Benchmarks for parser and formatter
## Key Design Decisions
- **Optional**: Listener is only started when `IRC_LISTEN_ADDR` is set
- **Shared infrastructure**: Same DB, broker, and session system as HTTP API
- **Full bridge**: IRC ↔ HTTP messages are interoperable
- **No schema changes**: Reuses existing tables
- **Broker as Fx dependency**: Extracted from handlers to be shared
## Supported Commands
Connection: NICK, USER, PASS, QUIT, PING/PONG, CAP
Channels: JOIN, PART, MODE, TOPIC, NAMES, LIST, KICK, INVITE
Messaging: PRIVMSG, NOTICE
Info: WHO, WHOIS, LUSERS, MOTD, AWAY, USERHOST
Operator: OPER
