Need to verify against other SDK implementations. + +--- + +### 2. RSA4b - key + clientId Does Not Auto-Trigger Token Auth + +**Issue:** The spec states that providing `key + clientId` should automatically trigger token auth. However, ably-go requires explicit `WithUseTokenAuth(true)`. + +**ably-go behavior:** Uses Basic auth unless `WithUseTokenAuth(true)` is also set. + +--- + +### 2a. RSA4b4 - Token Renewal Auto-Retry Not Implemented (REST) + +**Issue:** The spec (RSA4b4) states that when a request fails with a token error (40140-40149 range), the library should automatically obtain a new token and retry the request. However, ably-go's REST client does **not** implement this automatic retry behavior. + +**Expected behavior (per spec):** +1. Request fails with 40142 (Token expired) +2. Library automatically renews token via authCallback/authUrl +3. Library retries the original request with new token +4. Returns success to caller + +**ably-go REST behavior:** +1. Request fails with 40142 (Token expired) +2. Error is returned directly to caller (no automatic retry) + +**Skipped tests:** +- `TestTokenRenewal_RSA4b4_RenewalOnExpiryRejection` +- `TestTokenRenewal_RSA4b4_RenewalOn40140Error` +- `TestTokenRenewal_RSA4b4_RenewalWithAuthUrl` +- `TestTokenRenewal_RSA4b4_RenewalLimit` + +**Note:** Pre-emptive renewal (RSA14) - detecting an expired token *before* making a request - appears to work correctly. It's only the reactive retry-on-401 that's not implemented. + +**Investigation needed:** Is this behavior intentional (REST vs Realtime difference)? Do other SDKs implement auto-retry for REST? + +--- + +### 3. Host Naming Convention + +**Issue:** ably-go uses different host naming than the spec expects. + +| Spec expects | ably-go uses | +|--------------|--------------| +| `main.realtime.ably.net` | `rest.ably.io` | +| `sandbox.realtime.ably.net` | `sandbox-rest.ably.io` | + +**Skipped tests:** +- `TestFallback_REC1_DefaultEndpoint` +- `TestFallback_REC1_SandboxEndpoint` +- `TestFallback_RSC15a_FallbackHostsTried` +- `TestOptionsTypes_TO_EndpointHostSelection` + +--- + +### 4. ClientId Propagation Timing + +**Issue:** ably-go doesn't immediately populate `Auth.ClientID()` from TokenDetails provided at construction time. The clientId is only available after first authenticated request. + +**Skipped tests:** +- `TestClientId_RSA7b_FromTokenDetails` +- `TestClientId_RSA7_InheritFromToken` +- `TestClientId_RSA7_UpdatedAfterAuthorize` + +--- + +### 5. Message Encoding/Decoding + +**Issue:** ably-go's message encoding/decoding behavior differs from spec in several ways: +- Base64 decoding may return string instead of `[]byte` +- JSON decoding may not produce `map[string]interface{}` as expected +- Chained encoding handling differs +- Unrecognized encoding handling differs + +**Skipped tests:** +- `TestMessageEncoding_RSL6a_DecodingBase64` +- `TestMessageEncoding_RSL6a_DecodingJSON` +- `TestMessageEncoding_RSL6a_DecodingChainedEncodings` +- `TestMessageEncoding_RSL6b_UnrecognizedEncoding` + +--- + +### 6. TokenParams Missing Nonce Field (TK5) + +**Issue:** The spec says `TokenParams` should have a `nonce` field, but ably-go only has `Nonce` in `TokenRequest`, not `TokenParams`. + +--- + +### 6a. Error Code Differences (RSA4b) + +**Issue:** The spec expects error code 40106 (No authentication credentials) when no credentials are provided. ably-go returns different codes depending on context: +- `40005` - when no key or token provided +- `40101` - in some authentication error scenarios + +**Workaround:** Tests accept multiple error codes: `40005 || 40101 || 40106` + +--- + +### 6b. JWT Token Support (RSA8d, RSC18) + +**Issue:** The spec defines JWT token support where: +- `authCallback` can return a JWT string directly (RSA8d) +- The library should detect JWT format and use it appropriately (RSC18) + +**ably-go behavior:** JWT support needs investigation. The tests are skipped pending verification of how ably-go handles JWT tokens returned from authCallback. + +**Skipped tests:** +- `TestAuthScheme_RSC18_UsingJWT` +- `TestAuthCallback_RSA8d_JwtTokenReturned` + +--- + +### 7. ably-go Authorize() Nil Pointer Bug + +**Issue:** Calling `client.Auth.Authorize(ctx, nil, authOption...)` causes a nil pointer dereference when `authOption` is provided but `params` is nil. + +**Location:** `auth.go:358` - tries to set `params.Timestamp = 0` when `params` is nil + +**Workaround:** Always pass `&ably.TokenParams{}` instead of `nil` + +--- + +### 8. ably-go Uses Msgpack by Default + +**Issue:** Tests assume JSON encoding for request bodies, but ably-go uses msgpack by default. Tests use `ably.WithUseBinaryProtocol(false)` to force JSON for easier test inspection. + +--- + +### 9. Fallback Behavior Differences + +**Issue:** ably-go's fallback and retry behavior differs from spec: +- Empty fallback hosts may still trigger retries +- Cached fallback expiration timing differs +- Custom endpoint handling differs + +**Skipped tests:** +- `TestFallback_RSC15m_NoFallbackWhenEmpty` +- `TestFallback_RSC15f_CachedFallbackExpires` +- `TestFallback_REC2_CustomHostNoFallback` +- `TestFallback_REC2_CustomFallbackHosts` + +--- + +### 10. Pagination Behavior + +**Issue:** ably-go's Pages iterator behavior differs from spec: +- No `first()` method +- `Items()` behavior after `Next()` returns false differs + +**Skipped tests:** +- `TestPaginatedResult_TG4_FirstPage` +- `TestPaginatedResult_TG_NextOnLastPage` + +--- + +### 11. URL Encoding in Channel Names + +**Issue:** The spec expects URL-encoded channel names (e.g., `with%3Acolon`), but ably-go does NOT URL-encode special characters in channel name paths. + +**Test behavior:** Tests updated to expect ably-go's actual behavior with DEVIATION comments. + +--- + +### 12. UseTokenAuth Without Credentials + +**Issue:** ably-go allows `WithUseTokenAuth(true)` without other credentials, deferring the error to first request. Spec expects immediate error. + +**Skipped test case:** +- `TestClientOptions_RSC1b_InvalidArgumentsError/useTokenAuth_only` + +--- + +## Action Items + +### High Priority (Blocking spec compliance) +- [ ] **RSA4b4:** Investigate whether REST client should auto-retry on token expiry (40140-40149 errors) +- [ ] **RSA8d/RSC18:** Investigate JWT token support in ably-go +- [ ] **RSA4b:** Clarify whether token base64 encoding in Bearer header is intentional +- [ ] **RSA4b:** Determine if `key + clientId` should auto-trigger token auth + +### Medium Priority +- [ ] **RSA4b:** Investigate error code differences (40005 vs 40106 vs 40101) +- [ ] Report Authorize() nil pointer bug to ably-go maintainers (line 358) +- [ ] Investigate clientId propagation timing (RSA7b) +- [ ] Investigate message encoding/decoding differences (RSL6) + +### Low Priority +- [ ] Investigate host naming convention differences (rest.ably.io vs realtime.ably.net) +- [ ] Investigate fallback behavior differences (RSC15) +- [ ] Investigate pagination behavior differences (TG4) + +--- + +## Test Files Created + +### Authentication Tests +- `auth_scheme_spec_test.go` - RSA1-4, RSA4b, RSC18 auth scheme selection tests +- `auth_callback_spec_test.go` - RSA8c, RSA8d auth callback/authUrl tests (incl.
