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 closes #89 Co-authored-by: user <user@Mac.lan guest wan> Co-authored-by: Jeffrey Paul <sneak@noreply.example.org> Reviewed-on: sneak/chat#94 Co-authored-by: clawbot <sneak+clawbot@sneak.cloud> Co-committed-by: clawbot <sneak+clawbot@sneak.cloud> |

feat: add runtime statistics to healthcheck endpoint (#80)
check / check (push) Has been cancelled
## Summary Expands the `/.well-known/healthcheck.json` endpoint with runtime statistics, giving operators visibility into server load and usage patterns. closes #74 ## New healthcheck fields | Field | Source | Description | |-------|--------|-------------| | `sessions` | DB | Current active session count | | `clients` | DB | Current connected client count | | `queuedLines` | DB | Total entries in client output queues | | `channels` | DB | Current channel count | | `connectionsSinceBoot` | Memory | Total client connections since server start | | `sessionsSinceBoot` | Memory | Total sessions created since server start | | `messagesSinceBoot` | Memory | Total PRIVMSG/NOTICE messages since server start | ## Implementation - **New `internal/stats` package** — atomic counters for boot-scoped metrics (`connectionsSinceBoot`, `sessionsSinceBoot`, `messagesSinceBoot`). Thread-safe via `sync/atomic`. - **New DB queries** — `GetClientCount()` and `GetQueueEntryCount()` for current snapshot counts. - **Healthcheck changes** — `Healthcheck()` now accepts `context.Context` to query the database. Response struct extended with all 7 new fields. DB-derived stats populated with graceful error handling (logged, not fatal). - **Counter instrumentation** — Increments added at: - `handleCreateSession` → `IncrSessions` + `IncrConnections` - `handleRegister` → `IncrSessions` + `IncrConnections` - `handleLogin` → `IncrConnections` (new client for existing session) - `handlePrivmsg` → `IncrMessages` (covers both PRIVMSG and NOTICE) - **Wired via fx** — `stats.Tracker` provided through Uber fx DI in both production and test setups. ## Tests - `internal/stats/stats_test.go` — 5 tests covering all counter operations (100% coverage) - `TestHealthcheckRuntimeStatsFields` — verifies all 7 new fields are present in the response - `TestHealthcheckRuntimeStatsValues` — end-to-end: creates a session, joins a channel, sends a message, then verifies counts are nonzero ## README Updated healthcheck documentation with full response shape, field descriptions, and project structure listing for `internal/stats/`.
