Danny Avila	9f6d8c6e93	🧵 feat: ALS Context Middleware, Tenant Threading, and Config Cache Invalidation (#12407) ... * feat: add tenant context middleware for ALS-based isolation Introduces tenantContextMiddleware that propagates req.user.tenantId into AsyncLocalStorage, activating the Mongoose applyTenantIsolation plugin for all downstream DB queries within a request. - Strict mode (TENANT_ISOLATION_STRICT=true) returns 403 if no tenantId - Non-strict mode passes through for backward compatibility - No-op for unauthenticated requests - Includes 6 unit tests covering all paths * feat: register tenant middleware and wrap startup/auth in runAsSystem() - Register tenantContextMiddleware in Express app after capability middleware - Wrap server startup initialization in runAsSystem() for strict mode compat - Wrap auth strategy getAppConfig() calls in runAsSystem() since they run before user context is established (LDAP, SAML, OpenID, social login, AuthService) * feat: thread tenantId through all getAppConfig callers Pass tenantId from req.user to getAppConfig() across all callers that have request context, ensuring correct per-tenant cache key resolution. Also fixes getBaseConfig admin endpoint to scope to requesting admin's tenant instead of returning the unscoped base config. Files updated: - Controllers: UserController, PluginController - Middleware: checkDomainAllowed, balance - Routes: config - Services: loadConfigModels, loadDefaultModels, getEndpointsConfig, MCP - Audio services: TTSService, STTService, getVoices, getCustomConfigSpeech - Admin: getBaseConfig endpoint * feat: add config cache invalidation on admin mutations - Add clearOverrideCache(tenantId?) to flush per-principal override caches by enumerating Keyv store keys matching _OVERRIDE_: prefix - Add invalidateConfigCaches() helper that clears base config, override caches, tool caches, and endpoint config cache in one call - Wire invalidation into all 5 admin config mutation handlers (upsert, patch, delete field, delete overrides, toggle active) - Add strict mode warning when __default__ tenant fallback is used - Add 3 new tests for clearOverrideCache (all/scoped/base-preserving) * chore: update getUserPrincipals comment to reflect ALS-based tenant filtering The TODO(#12091) about missing tenantId filtering is resolved by the tenant context middleware + applyTenantIsolation Mongoose plugin. Group queries are now automatically scoped by tenantId via ALS. * fix: replace runAsSystem with baseOnly for pre-tenant code paths App configs are tenant-owned — runAsSystem() would bypass tenant isolation and return cross-tenant DB overrides. Instead, add baseOnly option to getAppConfig() that returns YAML-derived config only, with zero DB queries. All startup code, auth strategies, and MCP initialization now use getAppConfig({ baseOnly: true }) to get the YAML config without touching the Config collection. * fix: address PR review findings — middleware ordering, types, cache safety - Chain tenantContextMiddleware inside requireJwtAuth after passport auth instead of global app.use() where req.user is always undefined (Finding 1) - Remove global tenantContextMiddleware registration from index.js - Update BalanceMiddlewareOptions to include tenantId, remove redundant cast (Finding 4) - Add warning log when clearOverrideCache cannot enumerate keys on Redis (Finding 3) - Use startsWith instead of includes for cache key filtering (Finding 12) - Use generator loop instead of Array.from for key enumeration (Finding 3) - Selective barrel export — exclude _resetTenantMiddlewareStrictCache (Finding 5) - Move isMainThread check to module level, remove per-request check (Finding 9) - Move mid-file require to top of app.js (Finding 8) - Parallelize invalidateConfigCaches with Promise.all (Finding 10) - Remove clearOverrideCache from public app.js exports (internal only) - Strengthen getUserPrincipals comment re: ALS dependency (Finding 2) * fix: restore runAsSystem for startup DB ops, consolidate require, clarify baseOnly - Restore runAsSystem() around performStartupChecks, updateInterfacePermissions, initializeMCPs, and initializeOAuthReconnectManager — these make Mongoose queries that need system context in strict tenant mode (NEW-3) - Consolidate duplicate require('@librechat/api') in requireJwtAuth.js (NEW-1) - Document that baseOnly ignores role/userId/tenantId in JSDoc (NEW-2) * test: add requireJwtAuth tenant chaining + invalidateConfigCaches tests - requireJwtAuth: 5 tests verifying ALS tenant context is set after passport auth, isolated between concurrent requests, and not set when user has no tenantId (Finding 6) - invalidateConfigCaches: 4 tests verifying all four caches are cleared, tenantId is threaded through, partial failure is handled gracefully, and operations run in parallel via Promise.all (Finding 11) * fix: address Copilot review — passport errors, namespaced cache keys, /base scoping - Forward passport errors in requireJwtAuth before entering tenant middleware — prevents silent auth failures from reaching handlers (P1) - Account for Keyv namespace prefix in clearOverrideCache — stored keys are namespaced as "APP_CONFIG:_OVERRIDE_:..." not "_OVERRIDE_:...", so override caches were never actually matched/cleared (P2) - Remove role from getBaseConfig — /base should return tenant-scoped base config, not role-merged config that drifts per admin role (P2) - Return tenantStorage.run() for cleaner async semantics - Update mock cache in service.spec.ts to simulate Keyv namespacing * fix: address second review — cache safety, code quality, test reliability - Decouple cache invalidation from mutation response: fire-and-forget with logging so DB mutation success is not masked by cache failures - Extract clearEndpointConfigCache helper from inline IIFE - Move isMainThread check to lazy once-per-process guard (no import side effect) - Memoize process.env read in overrideCacheKey to avoid per-request env lookups and log flooding in strict mode - Remove flaky timer-based parallelism assertion, use structural check - Merge orphaned double JSDoc block on getUserPrincipals - Fix stale [getAppConfig] log prefix → [ensureBaseConfig] - Fix import order in tenant.spec.ts (package types before local values) - Replace "Finding 1" reference with self-contained description - Use real tenantStorage primitives in requireJwtAuth spec mock * fix: move JSDoc to correct function after clearEndpointConfigCache extraction * refactor: remove Redis SCAN from clearOverrideCache, rely on TTL expiry Redis SCAN causes 60s+ stalls under concurrent load (see #12410). APP_CONFIG defaults to FORCED_IN_MEMORY_CACHE_NAMESPACES, so the in-memory store.keys() path handles the standard case. When APP_CONFIG is Redis-backed, overrides expire naturally via overrideCacheTtl (60s default) — an acceptable window for admin config mutations. * fix: remove return from tenantStorage.run to satisfy void middleware signature * fix: address second review — cache safety, code quality, test reliability - Switch invalidateConfigCaches from Promise.all to Promise.allSettled so partial failures are logged individually instead of producing one undifferentiated error (Finding 3) - Gate overrideCacheKey strict-mode warning behind a once-per-process flag to prevent log flooding under load (Finding 4) - Add test for passport error forwarding in requireJwtAuth — the if (err) { return next(err) } branch now has coverage (Finding 5) - Add test for real partial failure in invalidateConfigCaches where clearAppConfigCache rejects (not just the swallowed endpoint error) * chore: reorder imports in index.js and app.js for consistency - Moved logger and runAsSystem imports to maintain a consistent import order across files. - Improved code readability by ensuring related imports are grouped together.	2026-03-26 17:35:00 -04:00
