Kamune v0.4.0

v0.4.0

Core Library

• Conn interface now embeds ReadWriter.
• Remove Router type; delete router.go, clean up routes.go.
• Centralize sentinel errors into root errors.go.
• Add AppVersion to Peer struct; consolidate RemotePeer() method.
• Add Ping/Pong routes with configurable keep-alive.
• Add SettingsBucket, GetSettings/SetSettings in storage (encrypted at rest).
• Add deterministic Pseudonym(seed) with expanded word pools.
• Expand fingerprint emoji pool from 64 to 96 entries.
• Delegate HPKE exchange from root to pkg/exchange; remove duplicate exchange.go.
• Merge ciphertext and public key into single exchange write (3 messages instead of 4).
• Add ErrPeerDisconnected sentinel; Transport.Close() returns gracefully instead of abrupt disconnect.
• Use local-time keys and versioned value envelope in chat storage.
• Remove QR code fingerprint display.
• Fix uint16 overflow in writeLen (check len(data) before cast).
• Track current read/write deadlines to prevent Ping timeout from being overwritten by read timeout.
• Fix data race in Server.ListenAndServe (lock around closed/listener access).
• Fix panic recovery in Dialer.handshake and Server.serve (close conn and return error instead of nil).
• Fix RelayListener.Close data race (lock mu around conn.Close).
• Fix RelayListener.closeFn double-call guard with sync.Once.

Relay

• Full service layer rewrite: replace with hub + session architecture.
• Remove old storage layer (command/logger/query/queue/store) and model packages.
• Add TCP adapter and TCP handler for direct connections.
• Extract pkg/relayconn with auth, dial, listener, transport modules.
• Add token+password authentication flow.
• Replace box proto with updated relay proto.
• Update config, router, and WebSocket handler for new architecture.
• Add Stop() method to RelayListener (prevents new accepts without killing active connections).
• Auto-generate self-signed TLS certificates as PEM; enable by default.
• Close peer channel on disconnect to prevent blocking.
• Add cross-platform build script; simplify Makefile.
• Simplify --version output to show kamune dependency version.
• Fix expired session goroutine leak (close listener/dialer channels before delete in purgeExpired).
• Fix TOCTOU in session Recipient (hold lock through switch instead of releasing early).
• Send TCP/TLS startup errors to errCh instead of only logging.
• Fix double-read from exitCh in TCP/TLS-only mode (read into variable).
• Add 30s context timeout for WebSocket handshake accept (wsAdapter.SetDeadline is a no-op).
• Enforce MaxMessageSize in TCP and TLS adapters.
• Log handlePing write errors instead of silent discard.
• Randomize self-signed TLS certificate serial number.
• Add // TODO for unimplemented rate limiting.

Bus

• Fingerprint computed on demand from public key (remove stored emojiFP/b64FP/hexFP fields).
• Native OS menu bar with Fingerprint submenu (Copy as Hex/Sum/Base64) with toast feedback.
• Session naming and version display.
• Persist name and verification mode across restarts; add MyName editing.
• KAMUNE_DB_PATH and KAMUNE_DB_PASSPHRASE env var support.
• Keychain UX improvements for relay credentials.
• Update relay.go for new relayconn API (token + password).
• Redesign frontend for multi-token relay, inline rename, and continuous session management.
• Add multi-token relay support with start cancellation and TLS toggle.
• Add native dialog confirmations and server restart on setting changes.
• Restructure onMount event registration to fix duplicate Wails event handlers.
• Use Stop() for graceful relay token consumption.
• Add server transport tracking, verifying connection state, and log export to file.
• Refresh history session list on session close; add missing fields to session info dialog.
• Handle ErrPeerDisconnected in receive loop.
• Update build script output path; add -s -w linker flags.
• Add keychain error default case (log warning instead of silent fallthrough).
• Offload ExportLogsToFile to goroutine with error reporting.
• Extract removeSession helper (DRY, avoid nil-slice panic on shutdown).
• Guard stale verification channel send with select/default (prevent goroutine leak on slow consumer).
• Remove hardcoded appVersion test (version now references kamune.AppVersion).
• Modernize test style: for i := range N, wg.Go in place of manual wg.Add/go/wg.Done.

TUI

• Full rewrite from CLI flag dispatch to interactive bubbletea menu TUI.
• Multi-state architecture (welcome, input, connecting, verify, chat, history).
• Interactive DB path and passphrase prompts before alt-screen.
• Direct TCP client/server, relay client/server, and chat history browsing.
• Peer verification screen with emoji + hex fingerprint display.
• Chat with viewport/textarea, message history loading, and send/receive.
• Version mismatch warning during connection.
• Handle ErrPeerDisconnected in receive loop.

Daemon

• Initial protocol documentation in docs/DAEMON.md.
• Handle ErrPeerDisconnected in receive loop.
• Fix shutdown and connection lifecycle races.
• Use env var for passphrase instead of interactive prompt.
• Handle RoutePing with pong response.
• Consistent base64 encoding for public keys.

Documentation

• SPEC.md updated to v0.4.0 with Ping/Pong, Server/Dialer, Keep-Alive.
• Add docs/RELAY.md with stateless relay architecture.
• Add docs/DAEMON.md with daemon protocol documentation.
• Update README with revised project status.

Miscellaneous

• Regenerate protobuf bindings for relay and box schemas.
• Fix Zed debug launch configuration paths.
• Bump module version to v0.4.0.
• Add build targets for relay and bus in root Makefile.
