Core SASL authentication compatibility fixes: * Add GaussDbScramSha256 authenticator with GaussDB-specific message handling * Add GaussDbSaslParser with three compatibility modes: - Standard: strict PostgreSQL compliance - GaussDB: handles trailing data in SASL messages - Auto: intelligent detection and fallback * Add CompatibilityMode enum for flexible parsing control * Add create_gaussdb_scram helper function for easy authenticator creation Technical improvements: * Fix 'invalid message length: expected to be at end of iterator for sasl' error * Handle GaussDB-specific SASL message format with trailing whitespace/control chars * Maintain full backward compatibility with standard PostgreSQL SASL * Add comprehensive unit tests (37 tests) covering all compatibility scenarios Resolves: SCRAM-SHA-256 authentication failures with GaussDB/openGauss servers
Intelligent authentication system for optimal database compatibility: * Add AdaptiveAuthManager for smart authentication method selection * Add server type detection (GaussDB/PostgreSQL/Unknown) based on version strings * Add authentication method preferences per server type: - GaussDB: SHA256 → MD5-SHA256 → SCRAM-SHA-256-GaussDB → MD5 → SCRAM-SHA-256-Standard - PostgreSQL: SCRAM-SHA-256-Standard → MD5 → SCRAM-SHA-256-GaussDB - Unknown: Default to GaussDB preferences for maximum compatibility * Add authentication statistics tracking for success/failure rates * Add AuthStrategy enum for different authentication approaches Features: * Automatic server compatibility detection from version strings * Intelligent fallback authentication method selection * Performance tracking and method usage statistics * Support for future authentication method extensions * Comprehensive unit tests covering all detection scenarios This enables automatic selection of the best authentication method for each database server type, improving connection success rates.
Enhanced connection logic with intelligent authentication fallback: Connection improvements: * Add dual authentication strategy: GaussDB-compatible first, standard fallback * Add authenticate_sasl_enhanced function using GaussDB SCRAM compatibility * Add detailed error logging and diagnostic information * Add graceful fallback from enhanced to standard authentication * Export adaptive_auth module for external use Technical enhancements: * Integrate AdaptiveAuthManager for server type detection * Use GaussDbScramSha256 authenticator for GaussDB servers * Maintain full compatibility with existing PostgreSQL connections * Add comprehensive error handling with actionable error messages * Optimize authentication flow for better performance Connection flow: 1. Attempt GaussDB-compatible SCRAM authentication 2. On failure, log detailed error and attempt standard authentication 3. Provide clear error messages for troubleshooting 4. Maintain connection statistics for monitoring This resolves SCRAM authentication issues while maintaining backward compatibility with all existing connection scenarios.
Smart runtime management for async environment compatibility: Runtime detection and management: * Add intelligent runtime detection using Handle::try_current() * Add connect_in_thread() for nested runtime scenarios * Add connect_with_new_runtime() for clean runtime environments * Add proper error handling for runtime creation failures Technical fixes: * Fix 'Cannot start a runtime from within a runtime' error * Enable sync client usage within async frameworks (axum, tokio, etc.) * Maintain backward compatibility with existing sync API * Add comprehensive error messages for runtime issues Implementation details: * Detect existing tokio runtime context before creating new runtime * Use separate thread execution for nested runtime scenarios * Graceful fallback between runtime strategies * Proper resource cleanup and error propagation Use cases resolved: * Using gaussdb sync client in axum web applications * Integration with tokio-based async applications * Mixed sync/async codebases requiring database access * Development and testing environments with existing runtimes This enables seamless use of the sync client in any environment without runtime conflicts or API changes.
Real-world validation test suite for SCRAM compatibility: Integration test coverage: * Basic connection establishment and validation * Server version detection and compatibility verification * Concurrent connection handling (multiple simultaneous connections) * Transaction support and commit/rollback functionality * Prepared statement creation and execution * Error handling and diagnostic validation * Config builder pattern testing Test environment support: * Environment variable configuration for flexible testing * Automatic test database availability detection * Graceful test skipping when database unavailable * Support for various GaussDB/openGauss versions Validation scenarios: * Connection string parsing and validation * Authentication method negotiation * Query execution and result handling * Connection lifecycle management * Error propagation and handling Real-world testing: * Verified against openGauss 7.0.0-RC1 * Multi-authentication method support (MD5, SHA256, SCRAM-SHA-256) * Performance and stability validation * Resource cleanup verification These tests ensure the SCRAM compatibility fixes work correctly in production-like environments with real database servers.
