Thanks for your effort. I will try it on my computer later. |
Complete the communication chain fixes by adding provider mapping in engine.go when parsing runtime configuration from frontend. Without this fix, when frontend sends provider='local' in runtime config (via handleAIGenerate), the engine would use 'local' directly, causing: - Log messages to show 'local' instead of 'ollama' - Inconsistency with other parts of the system that expect 'ollama' This completes the communication chain consistency: ✅ handleGetModels: maps 'local' → 'ollama' ✅ handleTestConnection: maps 'local' → 'ollama' ✅ handleUpdateConfig: maps 'local' → 'ollama' ✅ engine.go runtime config: maps 'local' → 'ollama' Related: 14cb1ed, e872853
Extend provider validation to include all supported providers: - 'deepseek': Cloud AI service used by frontend - 'local': Backward compatibility alias for 'ollama' - 'custom': Custom AI provider support Without these additions, config validation would reject valid provider configurations, preventing users from: - Saving deepseek configurations from UI - Loading legacy configs with 'local' provider - Using custom AI providers Changes: - AIConfig.DefaultService: ollama|openai|claude → ollama|openai|claude|deepseek|local|custom - AIService.Provider: ollama|openai|claude → ollama|openai|claude|deepseek|local|custom Related: 14cb1ed, e872853, 744b1f3
Critical fix for application startup without config file. Problem: - AIService.Model has validate:'required' but no default value - No default endpoint for ollama service - Without config.yaml or environment variables, app fails validation - Users cannot start the plugin out-of-the-box Solution: 1. Added default ollama endpoint: http://localhost:11434 2. Added default model: qwen2.5-coder:latest 3. Created minimal config.yaml for quick start Changes: - loader.go:450-451: Set defaults for endpoint and model - config.yaml: New minimal working configuration This allows the plugin to start successfully with: - No configuration file (uses defaults) - With config file (overrides defaults) - With environment variables (overrides both) Fixes application startup issues and enables out-of-the-box usage. Related: 78ed1fa, 744b1f3, 14cb1ed

This commit fixes serious runtime compatibility issues that prevented the AI plugin from working correctly when integrated with the main api-testing project. Changes: - Set ReadOnly flag to true (was incorrectly false) The plugin claimed to support write operations but didn't implement any TestSuite/TestCase CRUD methods, causing "method not implemented" errors when the main project attempted write operations. - Implement missing LoaderServer interface methods: * GetVersion() - Returns plugin version information * GetThemes() - Returns empty list (AI plugin doesn't provide themes) * GetTheme() - Returns error message * GetBindings() - Returns empty list (AI plugin doesn't provide bindings) * GetBinding() - Returns error message * PProf() - Returns empty profiling data Impact: - Prevents main project from calling unimplemented write methods - Eliminates "codes.Unimplemented" errors during integration - Provides proper responses for all potentially called interface methods - Improves plugin stability and compatibility The AI plugin now correctly identifies itself as read-only and properly implements all interface methods that the main project might call.
## Problem (Issue #1 - P0 Critical) The plugin was returning field name "content" but the main project (api-testing) expects "generated_sql", causing 100% AI功能 failure. ## Root Cause Field name mismatch between plugin response and main project expectations: - Plugin returned: {Key: "content", Value: simpleFormat} - Main project expected: result.Pairs["generated_sql"] ## Changes - pkg/plugin/service.go:497 - Changed "content" to "generated_sql" in handleAIGenerate - pkg/plugin/service.go:977 - Changed "content" to "generated_sql" in handleLegacyQuery - Added comprehensive regression tests in pkg/plugin/service_test.go ## Test Results ✅ All tests passing (6 test cases) ✅ Compilation successful ✅ No breaking changes to other functionality ## Impact - ✅ Restores 100% AI功能 - ✅ Compatible with main project api-testing - ✅ Maintains backward compatibility through legacy handler ## References - BUGFIX_PLAN.md Phase 1 Task 1.1 & 1.2 - Google Go Style Guide: Error handling best practices
- Replace 4 debug print statements with logging.Logger calls - Add truncateString helper for response preview - Improve log context with structured fields (provider, error, response_length) - All tests passing
Implements BUGFIX_PLAN.md Task 2.1 based on gRPC best practices: **Error Handling Strategy:** - Protocol errors (invalid params) → gRPC status.Error - Business logic errors (AI generation failed) → DataQueryResult with error fields **Changes:** - handleAIGenerate: Return error in Data fields (success=false, error, error_code) - handleLegacyQuery: Same error handling pattern - Prevents error masking between plugin and main project **Testing:** - Added TestSuccessFieldConsistency with 3 scenarios - Verifies error/success field exclusivity - All 7 plugin tests passing References: gRPC Go error handling patterns, Google Go Style Guide
Implements BUGFIX_PLAN.md Task 2.3 Option 1 (recommended): **Problem:** - Runtime client creation failures were silently falling back to default client - Users had no visibility when their configured provider failed to initialize - Configuration errors were masked, causing confusion **Solution:** - Explicitly return error when runtime client creation fails - Follow gRPC best practices: fail fast with clear error messages - Improved error context includes provider name **Changes:** - generator.go:242-252: Return error instead of silent fallback - Changed from Warning to Error log level - Error message format: "runtime client creation failed for provider %s: %w" **Impact:** - Users will now see clear error messages when provider configuration is invalid - Prevents misleading behavior where wrong provider is used silently - All AI package tests passing References: Google Go Style Guide error handling patterns
This change makes health checks optional and tolerant during client addition, preventing service registration failures during temporary unavailability. Changes: - Add AddClientOptions struct with SkipHealthCheck and HealthCheckTimeout fields - Modify AddClient to accept optional configuration for health check behavior - Use context.WithTimeout for configurable health check timeouts (default: 5s) - Log warnings instead of returning fatal errors when health check fails - Allow services to be registered even if temporarily unhealthy - Update service.go to use new AddClient signature with nil opts (defaults) This resolves the issue where services couldn't be configured during network issues, service restarts, or temporary unavailability. The plugin can now gracefully handle these situations while still logging diagnostic information. Addresses BUGFIX_PLAN.md Phase 2 Task 2.4 (P1 priority).
Add comprehensive error checking for type assertions in runtime configuration parsing to prevent silent failures and improve debugging. Changes: - pkg/ai/generator.go: Add type assertion error handling for max_tokens - Support both float64 and int types from JSON unmarshaling - Log warning when unexpected type is encountered - Fall back to default value with diagnostic information - pkg/ai/engine.go: Add type assertion error handling for max_tokens - Support both float64 and int types - Log warning with type and value information for debugging - Maintain default value when type mismatch occurs Benefits: - Better error visibility through structured logging - Graceful degradation with default values - Clear diagnostic information for troubleshooting - Prevents silent failures in configuration parsing Addresses BUGFIX_PLAN.md Phase 3 Task 3.1 (P2 priority).
Add InitializationError tracking to provide detailed diagnostic information when AI services fail to initialize or are unavailable: - Add InitializationError struct to capture component failures with context - Collect initialization errors in NewAIPluginService for AI Engine and AI Manager - Include provider details (endpoint, model, configured services) in error context - Enhance error responses in all handlers (generate, providers, models, etc.) - Provide comprehensive diagnostic information when operations fail This implements Phase 3 Task 3.2 from BUGFIX_PLAN.md, following gRPC Go best practices for error handling with detailed context. Related to: Phase 3 Task 3.2 - Enhanced Error Messages
Implement connection pooling to reuse HTTP clients across providers: - Add global HTTP client pool using sync.Map for concurrent safety - Implement getOrCreateHTTPClient with double-check locking pattern - Configure Transport with optimized settings: * MaxIdleConns: 100 (total pool size) * MaxIdleConnsPerHost: 10 (per-host limit) * IdleConnTimeout: 90s (keep connections alive) * HTTP/2 support enabled * Response header timeout: 30s * TLS handshake timeout: 10s - Update NewUniversalClient to use connection pool - Add structured logging for pool operations Benefits: - Reduces connection establishment overhead - Improves latency for repeated requests - Better resource utilization - Follows Go net/http best practices from context7 This implements Phase 3 Task 3.3 from BUGFIX_PLAN.md. Related to: Phase 3 Task 3.3 - HTTP Connection Pooling
Implement comprehensive Prometheus metrics following best practices: - Request counters with method, provider, and status labels - Histogram for request duration tracking (exponential buckets 0.1s to ~51.2s) - Gauge for service health status monitoring - Counters for token usage tracking - Gauge for concurrent request monitoring Integration points: - handleAIGenerate: Track request count, duration, concurrent requests, and status - handleHealthCheck: Update service health status gauge Metrics package provides clean API: - RecordRequest(method, provider, status) - RecordDuration(method, provider, duration) - SetHealthStatus(provider, healthy) - RecordTokens(method, provider, tokenType, count) - IncrementConcurrentRequests/DecrementConcurrentRequests References BUGFIX_PLAN.md Phase 3 Task 3.4
Remove over-engineered features not specified in BUGFIX_PLAN.md Task 3.4: Removed metrics: - aiTokensUsed (no token data available currently) - aiConcurrentRequests (not in plan) Removed functions: - RecordTokens() (unused) - IncrementConcurrentRequests() (not required) - DecrementConcurrentRequests() (not required) - MeasureDuration() (empty placeholder) Removed integrations: - Concurrent request tracking in handleAIGenerate - Health status update in handleHealthCheck Final implementation matches plan exactly: ✓ 3 metrics: aiRequestsTotal, aiRequestDuration, aiServiceHealth ✓ 3 functions: RecordRequest, RecordDuration, SetHealthStatus ✓ 1 integration point: handleAIGenerate only Code reduced from 140 to 77 lines (-45%) All tests passing
Changes: - Remove "// Metrics: record successful request" comment from service.go - Simplify package documentation in metrics.go to minimal form - Keep implementation exactly as specified in BUGFIX_PLAN.md lines 796-814 This completes the cleanup requested to ensure no unnecessary content remains in the metrics implementation.
- Fix unchecked error returns for Body.Close() in ollama discovery and universal client - Fix unchecked error return for client.Close() in manager connection test - Replace log.Fatalf with log.Panicf in main to ensure defer execution - All changes ensure proper resource cleanup and prevent potential leaks - Resolves golangci-lint errcheck and exitAfterDefer warnings
