86813b506b fix(ircserver): VERSION/ADMIN/TIME use serverSfx fallback
Some checks failed
check / check (push) Has been cancelled
WIP: c.cfg.ServerName defaults to "", so the three new wire handlers
emitted an empty server-name parameter under the shipped default config.
c.serverSfx already carries the same "neoirc" fallback the HTTP path
uses, and sendNumeric uses it for the prefix. Empty-ServerName test
follows.

c20ad88dfe fix: KILL actually disconnects the victim; unify HTTP/IRC divergences
All checks were successful
check / check (push) Successful in 1m12s
Addresses the 2026-08-10 FAIL review (findings 1-7, 9, 10).

KILL never terminated the victim's connection on either transport: both
paths called BroadcastQuit, which deletes the session row and tells the
victim's peers it quit, but leaves the victim holding a socket that looks
alive and silently delivers nothing while its nick is freed for reuse.
Service now owns a session-ID keyed registry of live wire connections that
ircserver populates at registration, and both KILL paths go through the new
Service.KillSession, which broadcasts the QUIT and then sends the victim a
KILL and ERROR :Closing Link before closing its socket. The victim's relay
goroutine is cancelled and its cleanup no longer re-broadcasts a QUIT for
an already-deleted session. TestIntegrationKill now asserts the victim
reads to EOF and is gone from NAMES and WHO, not just that an observer saw
the QUIT relay.

HTTP MODE <othernick> with no body answered with the requester's own modes,
because the target check sat inside the mode-change branch. The check is
hoisted above the query/change split, and both transports now compare nicks
with EqualFold since IRC nicks are case-insensitive.

Service.QueryUserMode returned "+" for a database failure, making an
unreadable mode indistinguishable from an unset one; it now returns an
error, and both callers surface it. db.GetUserhostInfo likewise treated
every scan error as "nick not found"; only sql.ErrNoRows is skipped now.

The four new unsynchronized c.nick reads this branch introduced are read
through currentNick() under c.mu, and c.closed is now guarded everywhere
because KILL writes it from another client's goroutine. Conn.send takes a
write mutex, as a connection is now written to by three goroutines.

server.Server.Run was left with no in-tree callers when its body was
inlined into the fx OnStart hook; it is deleted rather than left to drift.

INFO and VERSION had two implementations that had already diverged: the
version string is now Service.ServerVersion and the INFO body is
Service.InfoLines, used verbatim by both transports. The ctx parameters on
handleVersion/handleAdmin/handleInfo/handleTime existed only to be
discarded and are gone.

abe0cc2c30 refactor: unify user mode processing into shared service layer
Some checks failed
check / check (push) Failing after 2m28s
Both the HTTP API and IRC wire protocol handlers now call
service.ApplyUserMode/service.QueryUserMode for all user
mode operations. The service layer iterates mode strings
character by character (the correct IRC approach), ensuring
identical behavior regardless of transport.

Removed duplicate mode logic from internal/handlers/utility.go
(buildUserModeString, applyUserModeChange, applyModeChar) and
internal/ircserver/commands.go (buildUmodeString, inline iteration).

Added service-level tests for QueryUserMode, ApplyUserMode
(single-char, multi-char, invalid input, de-oper, +o rejection).

17479c4f44 fix: rebase onto main, add IRC wire handlers and integration tests for Tier 3 commands
Some checks failed
check / check (push) Failing after 2m10s
Rebase onto main to resolve conflicts from module path rename
(sneak.berlin/go/neoirc) and integration test addition.

- Update import paths in utility.go to new module path
- Add IRC wire protocol handlers for VERSION, ADMIN, INFO,
  TIME, KILL, and WALLOPS to ircserver/commands.go
- Register all 6 new commands in the IRC command dispatch map
- Implement proper user MODE +w/-w support for WALLOPS
- Add WALLOPS relay delivery in relay.go
- Add integration tests for all 7 Tier 3 commands:
  USERHOST, VERSION, ADMIN, INFO, TIME, KILL, WALLOPS
- Add newTestEnvWithOper helper for oper-dependent tests

f829f9e3da Change module path to sneak.berlin/go/neoirc (#99)
Some checks failed
check / check (push) Failing after 1m22s
Changes the Go module path from `git.eeqj.de/sneak/neoirc` to `sneak.berlin/go/neoirc`.

All occurrences updated:
- `go.mod` module directive
- All Go import paths across 35 `.go` files (107 import statements)
- All JSON schema `$id` URIs across 30 `.json` files in `schema/`

No functional changes — this is a pure rename of the module path.

`docker build .` passes clean (formatting, linting, all tests, binary build).

closes #98

0250f14fea feat: add traditional IRC wire protocol listener (closes #89) (#94)
All checks were successful
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
