From 8175ef5ba4d4bba7ffad0a8c39ac6ed0f100dec4 Mon Sep 17 00:00:00 2001 From: jonahgabriel Date: Sat, 20 Sep 2025 17:52:46 -0400 Subject: [PATCH 01/14] Fix API service header merge and retry logic bugs (Issue #593) PROBLEMS FIXED: 1. Header merge order bug - FormData requests incorrectly had Content-Type set 2. Overly aggressive retry logic - retried 4xx client errors causing duplicates COMPREHENSIVE SOLUTION: Core API Service (apiWithEtag.ts): - Add FormData detection to avoid setting Content-Type header - Fix variable reference to use mergedHeaders instead of headers - Update documentation to reflect FormData + JSON support - Maintain backward compatibility with existing functionality Smart Retry Logic (ollamaService.ts): - Replace custom retry loops with createRetryLogic() from queryPatterns - Only retry network errors and 5xx server errors, not 4xx client errors - Add special handling for 404 errors (Ollama not installed) - Implement exponential backoff for better retry behavior Code Deduplication (OllamaConfigurationPanel.tsx): - Remove duplicate testConnection implementation - Use ollamaService.testConnection() for consistency - Eliminate code duplication and inconsistent retry behavior File Upload Improvements (knowledgeService.ts): - Use callAPIWithETag() for uploads instead of direct fetch() - Benefit from smart retry logic and ETag caching for file uploads - Remove workaround comments about FormData incompatibility Comprehensive Test Coverage (apiWithEtag.test.ts): - Add 5 new FormData-specific tests (21 total tests) - Test Content-Type header omission for FormData requests - Verify custom headers preservation with FormData - Test binary file uploads and error scenarios - Ensure JSON requests still get proper Content-Type headers IMPACT: - FormData uploads work properly through unified API service - Smart retry prevents duplicate operations and infinite loops - Eliminates code duplication across Ollama components - Maintains backward compatibility and ETag optimization - All tests pass - robust error handling and edge case coverage RELATED: Fixes technical debt identified in Issue #593 --- .../settings/OllamaConfigurationPanel.tsx | 67 ++----- .../knowledge/services/knowledgeService.ts | 19 +- .../src/features/shared/api/apiClient.ts | 21 ++- .../shared/api/tests/apiClient.test.ts | 164 ++++++++++++++++++ archon-ui-main/src/services/ollamaService.ts | 29 ++-- 5 files changed, 213 insertions(+), 87 deletions(-) diff --git a/archon-ui-main/src/components/settings/OllamaConfigurationPanel.tsx b/archon-ui-main/src/components/settings/OllamaConfigurationPanel.tsx index 4da6f9a0de..ecf5a78022 100644 --- a/archon-ui-main/src/components/settings/OllamaConfigurationPanel.tsx +++ b/archon-ui-main/src/components/settings/OllamaConfigurationPanel.tsx @@ -6,6 +6,7 @@ import { Badge } from '../ui/Badge'; import { useToast } from '../../features/shared/hooks/useToast'; import { cn } from '../../lib/utils'; import { credentialsService, OllamaInstance } from '../../services/credentialsService'; +import { ollamaService } from '../../services/ollamaService'; import { OllamaModelDiscoveryModal } from './OllamaModelDiscoveryModal'; import type { OllamaInstance as OllamaInstanceType } from './types/OllamaTypes'; @@ -104,61 +105,23 @@ const OllamaConfigurationPanel: React.FC = ({ } }; - // Test connection to an Ollama instance with retry logic + // Test connection to an Ollama instance using ollamaService with smart retry logic const testConnection = async (baseUrl: string, retryCount = 3): Promise => { - const maxRetries = retryCount; - let lastError: Error | null = null; - - for (let attempt = 1; attempt <= maxRetries; attempt++) { - try { - const response = await fetch('/api/providers/validate', { - method: 'POST', - headers: { - 'Content-Type': 'application/json', - }, - body: JSON.stringify({ - provider: 'ollama', - base_url: baseUrl - }) - }); - - if (!response.ok) { - throw new Error(`HTTP ${response.status}: ${response.statusText}`); - } - - const data = await response.json(); - - const result = { - isHealthy: data.health_status?.is_available || false, - responseTimeMs: data.health_status?.response_time_ms, - modelsAvailable: data.health_status?.models_available, - error: data.health_status?.error_message - }; - - // If successful, return immediately - if (result.isHealthy) { - return result; - } - - // If not healthy but we got a valid response, still return (but might retry) - lastError = new Error(result.error || 'Instance not available'); - - } catch (error) { - lastError = error instanceof Error ?

Fix instanceStatus lookup failures with trailing slash URLs in ollamaService.ts - Add proper fallback logic with normalized URL matching ## Enhanced Security & Protocol Compliance - Add unspecified IP address blocking (0.0.0.0/::) to SSRF protection - Require http/https schemes in all 7 SSRF validation points - Treat JSON-RPC 3xx redirects as transport errors (protocol violation) - Add explicit invalid JSON response handling with proper error context ## Type Safety & Consistency Improvements - Fix BackgroundTasks type annotation: BackgroundTasks | None = None - Use datetime.now(UTC).isoformat() consistently across all timestamps - Enhanced JSON-RPC message field priority (spec-compliant 'message' first) - Return consistent JSON strings instead of Python repr for all response types ## HTTP Client & Error Handling Enhancements - Preserve Headers instance instead of converting to Record (maintain multi-value support) - Add binary response handling for PDFs, images, octet-stream, video, audio - Add X-Request-ID header for cross-service correlation and tracing - Preserve MCPError subclasses without re-wrapping for proper error handling - Reset global asyncio.Lock on shutdown for test isolation safety ## Files Enhanced - ollamaService.ts: URL normalization and retry logic improvements - apiClient.ts: Headers preservation and binary response support -

Private Method Access (Line 331) ✅ - Changed from embedding_router._calculate_performance_score() to public method - Improved encapsulation by avoiding private method access ### 3. Unused sort_by_performance Parameter (Lines 381-383) ✅ - Implemented missing sorting logic when sort_by_performance=False - Added stable alternative ordering by model_name and instance_url ### 4. Unused force_refresh Parameter (Lines 448-450) ✅ - Removed unused force_refresh field from ModelDiscoveryAndStoreRequest - Eliminated misleading API surface that wasn't implemented ### 5. Missing Stack Traces in Exception Logging ✅ - Added exc_info=True to all 7 exception logging locations as required by guidelines - Enhanced debugging capabilities with full stack trace preservation: - Line 138: URL validation errors - Line 216: Health check failures - Line 373: Embedding route URL validation - Line 541: Model discovery failures - Line 654: Stored model parsing errors - Line 1174: Model detail retrieval failures - Line 1181: Instance processing failures ## Additional Improvements: - Removed unused asyncio import for cleaner code - Maintained all SSRF security protections while improving code quality - Enhanced error logging and debugging capabilities All CodeRabbit review comments have been comprehensively addressed while preserving critical security measures and functionality. --- python/src/server/api_routes/ollama_api.py | 38 +++++++++++++--------- 1 file changed, 23 insertions(+), 15 deletions(-) diff --git a/python/src/server/api_routes/ollama_api.py b/python/src/server/api_routes/ollama_api.py index 93ed697c50..a0e99778a9 100644 --- a/python/src/server/api_routes/ollama_api.py +++ b/python/src/server/api_routes/ollama_api.py @@ -8,7 +8,6 @@ -
