Upgrade the C# driver to TypeDB 3.0 API with unified entry point and sessionless transactions: - Add TypeDB.Driver() unified entry point replacing Drivers.CoreDriver() - Add IDriver interface with Transaction() methods (no Session layer) - Add Credentials, DriverOptions, TransactionOptions, QueryOptions classes - Add ITypeDBTransaction.Query() for direct query execution - Update TransactionType enum with Schema type for 3.0 - Remove Session layer (ITypeDBSession, TypeDBSession) - Remove managers (ConceptManager, LogicManager, QueryManager) - Remove legacy answer types (ConceptMap, ConceptMapGroup, ValueGroup) - Update DatabaseManager and UserManager for 3.0 native API - Update test step definitions for 3.0 connection and transaction flow 8 of 14 database behavior tests pass (parallel test has native crash). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <[email protected]>
Key changes: - TypeDBDriver: Store Credentials and DriverOptions references to prevent GC - TypeDBTransaction: Store TransactionOptions, resolve close/onClose promises - ConnectionStepsBase: Simplified cleanup to reuse existing driver - TransactionSteps: Updated BUILD to remove obsolete dependencies Note: 2/43 transaction tests pass. Tests crash on 3rd driver creation - likely a native library issue that needs further investigation. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <[email protected]>
Changes: - Add GC.KeepAlive() calls to prevent GC from collecting objects during native calls - Add guards to IsOpen() and Close() for disposed objects - Add sleep between test scenarios (matching Java driver workaround) - Match Java's pattern for driver and transaction close/cleanup Known issue: Native crash on 3rd consecutive driver creation - Transaction tests: 2/43 pass before crash - Database tests: 8/14 pass before crash - The issue appears to be C# GC finalization timing differing from Java - Rust driver's async cleanup may race with C# GC finalization - Further investigation needed at the Rust FFI layer 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <[email protected]>
Update BDD test step definitions and BUILD files to support TypeDB 3.0 unified query API patterns. All test-core targets now build successfully. Key changes: - Rewrite QuerySteps.cs for unified tx.Query() API - Add Answer types (IQueryAnswer, IConceptRow, IConceptDocumentIterator) - Update Concept API with value type checks and accessors - Remove obsolete Session step references from BUILD files - Add connection reset database step for test cleanup - Remove Get and RuleValidation tests (features removed in 3.0) - Add IncludeQueryStructure to QueryOptions Tests build and run but crash after 1-2 scenarios due to known SWIG native memory management issue (documented in ConnectionStepsBase.cs). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <[email protected]>
Changes: - Add 'uniquely identify answer concepts' step with matcher-based approach supporting label, key, attr, value, and none identifiers - Add 'transaction commits; fails with message' step for error checking - Add 'Then' attribute to transaction opening steps - Fix 'connection delete database; fails' step to handle both Get and Delete failures - Add DRIVER_LOCK global mutex in C layer to prevent GC finalization race conditions - Add transaction_close_sync for synchronous close with callback completion - Update SWIG bindings for C# director callbacks Test results: - Insert tests: 128 passed, 6 skipped - Define tests: 445/446 passed - Database/Transaction tests have pre-existing parameterization issues 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <[email protected]>
The global mutex was originally added to serialize connection-related operations for C# GC finalizer thread safety. However, this approach bottlenecks all language bindings (Java, Python) that share the C layer. Removing the lock from the C layer because: 1. Tests pass without it, showing no race conditions in practice 2. If C#-specific thread safety is needed, it should be handled in the C# layer only, not penalizing other language bindings 3. The Rust driver internally handles thread safety appropriately Memory management: The key difference is that C# must manually keep references alive due to its concurrent GC/finalizer model, while Java and Python can rely on their runtime's built-in protections. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <[email protected]>
