* feat(sso): feishu OAuth2 single sign-on (ISSUE #405 P0)
Implements the SSO design (ISSUE #405) with feishu as the first IdP
and a generic OAuth2 provider abstraction for future dingtalk/wecom
extensions. SSO is disabled by default — existing deployments are
unaffected until mateclaw.sso.enabled=true.
Backend:
- SsoProvider interface + SsoUserInfo record: generic IdP abstraction
- FeishuSsoProvider: OAuth2 authorization-code flow (app_access_token
with Caffeine cache → user_access_token → user info). apiBase switches
between feishu.cn / larksuite.com by domain config.
- SsoProviderRegistry: conditional registration, lists enabled providers
- SsoStateService: HMAC-signed OAuth2 state + self-contained bind_token
JWT, both persisted to sso_state DB table for multi-node correctness.
State is one-time-consumable (conditional UPDATE), bind_token jti
anti-replay via PK insert. Hourly ShedLock purge (LambdaQuery + Java
time, works on all 3 dialects).
- SsoService: authorize/callback/bind, user mapping (union_id first →
external_id fallback), auto-create with concurrent idempotency
(DuplicateKeyException → rollback orphan user → re-query), link-only
mode issues bind_token for existing-account binding.
- SsoController: 4 endpoints (/providers, /authorize, /callback, /bind)
all permitAll.
- V159 migration (h2/mysql/kingbase): mate_user_external_identity,
sso_state, ALTER mate_user.password NULL (SSO-only users).
- AuthService: generateToken promoted to public; login() guards
password=null (SSO-only users cannot password-login).
- SecurityConfig: /auth/sso/** added to permitAll whitelist.
- LoginRateLimitFilter: expanded to cover /auth/sso/bind (brute-force
surface equivalent to /auth/login).
- application.yml: mateclaw.sso.* config block (all env-var driven).
Frontend:
- Login.vue: dynamic SSO buttons (only shown when providers configured),
OAuth2 callback detection (?sso=callback), link-only bind dialog,
shared applyLogin flow (localStorage + workspace + route).
- api/index.ts: ssoApi (providers, authorize, callback, bind).
Tests: SsoStateServiceTest (11) — state issue/verify/replay/tamper,
bind_token issue/verify/anti-replay/garbage. Regression: PAT (23) +
Approval resolve (13) all green.
Not in scope (P1/P2): link-only bind/unbind management endpoints,
user enable/disable endpoint, dingtalk/wecom providers, admin SSO
config page. Workspace assignment for auto-created users remains a
product decision (design doc §12 item 2).
* fix(sso): self-review fixes — P0 security + P1 quality
P0-1 BindRequired serialization: replaced the R.fail(200, Map.toString())
hack with a structured SsoCallbackResponse record. Controller no longer
catches an exception for a non-error path; frontend reads bindRequired
flag directly instead of regex-parsing a stringified map.
P0-2 createSsoUser unbounded recursion: added a retry flag — second
DuplicateKeyException (extreme race where identity was concurrently
deleted) now throws a 503 instead of recursing to stack overflow.
P0-3 state TTL not enforced: verifyState's conditional UPDATE now
includes created_at > cutoff, so a state unused for 5+ min is rejected
at consumption time, not just at the 1h purge. Without this the 5-min
window was advisory only.
P1-5 SsoStateService unused ObjectMapper: removed dead injection.
P1-6 audit JSON string concat: replaced with ObjectMapper serialization
(provider/externalId no longer risk breaking the JSON structure).
P1-7 LoginRateLimitFilter shared counter: documented the intentional
decision that login + bind share a per-IP counter (same brute-force
surface) with guidance on switching to per-path if finer isolation
is needed.
The PRIVATE_ITEMS list contained the bare 'test' entry, which rsync
interprets as 'any directory named test at any depth' — so it caught
the root-level /test/ scratch directory (intended) AND every src/test/
under each module (not intended).
Pattern is already anchored to /test (root-only). This commit rsyncs
the accumulated src/test/ tree forward so opensource has the unit tests
that have been written / updated against existing src/main/ code since
the pattern regression. Going forward each per-commit sync will carry
src/test/ files along with the main change.
