Summary

Major auth refactor replacing Bearer token authentication with HttpOnly cookie-based auth, removing the registration endpoint, and adding the PASS IRC command for password management.

Changes

Removed

  • POST /api/v1/register endpoint (no separate registration path)
  • RegisterUser DB method
  • Authorization: Bearer header parsing
  • token field from all JSON response bodies
  • Token field from CLI SessionResponse type

Added

  • Cookie-based authentication: neoirc_auth HttpOnly cookie set on session creation and login
  • PASS IRC command: set a password on the authenticated session via POST /api/v1/messages {"command":"PASS","body":["password"]} (minimum 8 characters)
  • SetPassword DB method (bcrypt hashing)
  • Cookie helpers: setAuthCookie(), clearAuthCookie()
  • Cookie properties: HttpOnly, SameSite=Strict, Secure when behind TLS, Path=/
  • CORS updated: AllowCredentials: true with origin reflection function

Auth Flow

  1. POST /api/v1/session {"nick":"alice"} → sets neoirc_auth cookie, returns {"id":1,"nick":"alice"}
  2. (Optional) POST /api/v1/messages {"command":"PASS","body":["s3cret"]} → sets password for multi-client
  3. Another client: POST /api/v1/login {"nick":"alice","password":"s3cret"} → sets neoirc_auth cookie
  4. Logout and QUIT clear the cookie

Tests

  • All existing tests updated to use cookies instead of Bearer tokens
  • New tests: TestPassCommand, TestPassCommandShortPassword, TestPassCommandEmpty, TestSessionCookie
  • Register tests removed
  • Login tests updated to use session creation + PASS command flow

README

  • Extensively updated: auth model documentation, API reference, curl examples, security model, design principles, roadmap
  • All Bearer token references replaced with cookie-based auth
  • Register endpoint documentation removed
  • PASS command documented

CI

  • docker build . passes (format check, lint, all tests, build)

closes #83

## Summary Major auth refactor replacing Bearer token authentication with HttpOnly cookie-based auth, removing the registration endpoint, and adding the PASS IRC command for password management. ## Changes ### Removed - `POST /api/v1/register` endpoint (no separate registration path) - `RegisterUser` DB method - `Authorization: Bearer` header parsing - `token` field from all JSON response bodies - `Token` field from CLI `SessionResponse` type ### Added - **Cookie-based authentication**: `neoirc_auth` HttpOnly cookie set on session creation and login - **PASS IRC command**: set a password on the authenticated session via `POST /api/v1/messages {"command":"PASS","body":["password"]}` (minimum 8 characters) - `SetPassword` DB method (bcrypt hashing) - Cookie helpers: `setAuthCookie()`, `clearAuthCookie()` - Cookie properties: HttpOnly, SameSite=Strict, Secure when behind TLS, Path=/ - CORS updated: `AllowCredentials: true` with origin reflection function ### Auth Flow 1. `POST /api/v1/session {"nick":"alice"}` → sets `neoirc_auth` cookie, returns `{"id":1,"nick":"alice"}` 2. (Optional) `POST /api/v1/messages {"command":"PASS","body":["s3cret"]}` → sets password for multi-client 3. Another client: `POST /api/v1/login {"nick":"alice","password":"s3cret"}` → sets `neoirc_auth` cookie 4. Logout and QUIT clear the cookie ### Tests - All existing tests updated to use cookies instead of Bearer tokens - New tests: `TestPassCommand`, `TestPassCommandShortPassword`, `TestPassCommandEmpty`, `TestSessionCookie` - Register tests removed - Login tests updated to use session creation + PASS command flow ### README - Extensively updated: auth model documentation, API reference, curl examples, security model, design principles, roadmap - All Bearer token references replaced with cookie-based auth - Register endpoint documentation removed - PASS command documented ### CI - `docker build .` passes (format check, lint, all tests, build) closes https://git.eeqj.de/sneak/chat/issues/83

cd9fd0c5c5 
- Remove POST /api/v1/register endpoint entirely
- Session creation (POST /api/v1/session) now sets neoirc_auth HttpOnly
  cookie instead of returning token in JSON body
- Login (POST /api/v1/login) now sets neoirc_auth HttpOnly cookie
  instead of returning token in JSON body
- Add PASS IRC command for setting session password (enables multi-client
  login via POST /api/v1/login)
- All per-request auth reads from neoirc_auth cookie instead of
  Authorization: Bearer header
- Cookie properties: HttpOnly, SameSite=Strict, Secure when behind TLS
- Logout and QUIT clear the auth cookie
- Update CORS to AllowCredentials:true with origin reflection
- Remove Authorization from CORS AllowedHeaders
- Update CLI client to use cookie jar (net/http/cookiejar)
- Remove Token field from SessionResponse
- Add SetPassword to DB layer, remove RegisterUser
- Comprehensive test updates for cookie-based auth
- Add tests: TestPassCommand, TestPassCommandShortPassword,
  TestPassCommandEmpty, TestSessionCookie
- Update README extensively: auth model, API reference, curl examples,
  security model, design principles, roadmap

Review: PR #84 — Auth Refactor (Bearer tokens → HttpOnly cookies)

Verdict: PASS ✅

Verification Points

# Requirement Status Notes
1 Cookie properties (HttpOnly, Secure when TLS, SameSite=Strict) ✅ setAuthCookie() correctly sets all three. Secure checks both request.TLS and X-Forwarded-Proto for reverse proxy support. clearAuthCookie() mirrors the same properties with MaxAge: -1.
2 No token in JSON responses ✅ handleCreateSession and handleLogin both return only {"id", "nick"}. SessionResponse type in CLI also has only ID + Nick. Test TestSessionCookie explicitly asserts no token key exists in the JSON body.
3 PASS command (min 8 chars, bcrypt) ✅ handlePass validates empty/missing body → ERR_NEEDMOREPARAMS (461), short password (<8) → ERR_NEEDMOREPARAMS, then calls database.SetPassword() which uses bcrypt.GenerateFromPassword at default cost. Three tests cover this: TestPassCommand, TestPassCommandShortPassword, TestPassCommandEmpty.
4 Register endpoint removed ✅ /register route gone from routes.go. HandleRegister function removed. RegisterUser DB method removed. grep confirms no register references remain (only IRC numerics).
5 Bearer auth removed ✅ grep -rn "Bearer|Authorization" --include="*.go" returns nothing. authSession() now reads from request.Cookie(authCookieName). Authorization removed from CORS AllowedHeaders.
6 CORS with AllowCredentials: true ✅ Uses AllowOriginFunc (reflects origin, not *), AllowCredentials: true.
7 Logout/QUIT clear cookie ✅ Both handleQuit and HandleLogout call clearAuthCookie() which sets MaxAge: -1.
8 CLI client uses cookie jar ✅ Client.Token field removed. NewClient() creates cookiejar.New(nil) and sets Jar on HTTPClient. PollMessages shares the jar. do() no longer sets Authorization header.
9 README updated ✅ Extensive updates: auth model, API reference, curl examples (-c/-b cookies.txt), Python/JS examples, security model, roadmap.
10 Tests updated ✅ doRequestAuth uses cookies. createSession extracts cookie from response. Register tests replaced with PASS command tests. New TestSessionCookie validates HttpOnly, SameSite, and no-token-in-body.

Build Result

docker build . — PASSED
- make fmt-check: PASSED
- make lint: PASSED  
- make test: ALL TESTS PASSED
- Binary build: PASSED (neoircd + neoirc-cli)

Code Quality Notes

Positive:

  • Clean separation of cookie helpers (setAuthCookie/clearAuthCookie) reused consistently across session creation, login, logout, and QUIT
  • PASS command correctly follows IRC error semantics (errors via message queue with numeric replies, not HTTP error codes)
  • Login handler properly initializes channel state for new clients via initChannelState()
  • Cookie jar sharing in the CLI client's poll client is correctly handled

Minor Documentation Nits (non-blocking)

A few stale token references survived in README sections adjacent to or near changed lines:

  1. Line 834: "Subsequent requests with the old token return HTTP 401" — should be "old cookie" (2 lines after a line that WAS changed)
  2. Line 2231: "POST /api/v1/session → get token" in Minimal Client Loop — should say "→ get auth cookie"
  3. Lines 237-239: Diagram uses token_a, token_b, token_c — could be cookie_a etc.

None affect functionality. Worth a follow-up cleanup.
