Phase 7: Comprehensive error handling and edge cases
- Added centralized errors.go with complete Kafka error code definitions - Implemented timeout detection and network error classification - Enhanced connection handling with configurable timeouts and better error reporting - Added comprehensive error handling test suite with 21 test cases - Unified error code usage across all protocol handlers - Improved request/response timeout handling with graceful fallbacks - All protocol and E2E tests passing with robust error handling

## Phase 6: Basic Flexible Versions Support (COMPLETED ✅)
|
||||
**Goal**: Basic support for flexible versions and tagged fields
|
||||
|
||||
### Tasks:
|
||||
- [ ] Add flexible version detection in request headers
|
||||
- [ ] Implement tagged field parsing/skipping
|
||||
- [ ] Update response encoders for flexible versions
|
||||
- [ ] Add flexible version tests
|
||||
- [x] Add flexible version detection in request headers
|
||||
- [x] Implement tagged field parsing/skipping (with backward compatibility)
|
||||
- [x] Update response encoders for flexible versions (ApiVersions v3+)
|
||||
- [x] Add flexible version tests
|
||||
|
||||
**Files to modify**:
|
||||
- `weed/mq/kafka/protocol/handler.go`
|
||||
- `weed/mq/kafka/protocol/flexible_versions.go` (new file)
|
||||
- Add test file: `weed/mq/kafka/protocol/flexible_versions_test.go`
|
||||
**Files modified**:
|
||||
- `weed/mq/kafka/protocol/handler.go` (added header parsing with fallback)
|
||||
- Added file: `weed/mq/kafka/protocol/flexible_versions.go`
|
||||
- Added test file: `weed/mq/kafka/protocol/flexible_versions_test.go`
|
||||
- Added test file: `weed/mq/kafka/protocol/flexible_versions_integration_test.go`
|
||||
|
||||
**Verification**: 27 flexible version tests pass; robust fallback for older clients; E2E compatibility maintained
