Please check the PR description - it should follow the rules as suggested by the workflow, The GH issue/ADO Item is missing. Just to add the reference we're working on GH Issue #148. Please make the changes as suggested, I'll mark it ready for review post that. Also, the PR title should be a FIX instead of a FEAT I believe, since we're fixing the workflows, processes and documentation for external contributors. Please let me know if you think otherwise.

The main motivation is to eliminate a circular import issue that caused failures on Alpine Linux due to musl libc's stricter dynamic loading rules. The Python helper and its associated test have been removed, and equivalent logic is now handled in C++. The test suite has been updated to validate the new C++-based resolution. Refactor: Move driver path resolution to C++ * Removed the `get_driver_path` function from `mssql_python/helpers.py`, eliminating Python-based driver path resolution. * Implemented `GetDriverPathCpp` in `mssql_python/pybind/ddbc_bindings.cpp` to handle all platform and architecture-specific ODBC driver path resolution in C++. This avoids Python dependencies during module initialization and resolves the Alpine Linux circular import issue. [[1]](diffhunk://#diff-dde2297345718ec449a14e7dff91b7bb2342b008ecc071f562233646d71144a1L640-R713) [[2]](diffhunk://#diff-dde2297345718ec449a14e7dff91b7bb2342b008ecc071f562233646d71144a1L665-R729) * Updated the C++ Python bindings to expose `GetDriverPathCpp` instead of the removed Python function. Testing updates * Removed tests for the old Python helper and added a new test to validate the C++ `GetDriverPathCpp` function against expected driver paths derived in Python. [[1]](diffhunk://#diff-e489a2a29f29954dcd0b17a34b15e53ee2aa4fa1def0a5a466bcee81df59ddf0L318-L332) [[2]](diffhunk://#diff-e489a2a29f29954dcd0b17a34b15e53ee2aa4fa1def0a5a466bcee81df59ddf0R364-R380) * Added helper imports and a method to compute the expected driver path in the test suite for accurate cross-validation.

The changes include adding new tests for connection pooling performance and connection reuse, as well as improving the structure and clarity of the existing test logic. ### Enhancements to connection pooling tests: * **Performance testing for pooled vs. non-pooled connections:** - Added a new test (`test_connection_pooling_speed`) to measure and compare the average time taken for establishing connections with and without pooling. The test ensures that pooled connections are at least 20% faster than non-pooled connections. * **Connection reuse validation:** - Introduced a new test (`test_connection_pooling_reuse_spid`) to verify that connections are reused from the pool. The test checks that the SQL Server process ID (`SPID`) remains consistent across reused connections, indicating proper pooling behavior. * **Improved test setup and cleanup:** - Added explicit enabling and disabling of connection pooling at the start and end of tests to ensure isolation and prevent interference with other tests. These changes improve the reliability and comprehensiveness of the connection pooling tests.  --------- Co-authored-by: Sumit Sarabhai <sumitsar@microsoft.com>

It also introduces comprehensive test coverage for this new method in `tests/test_004_cursor.py`. Additionally, the `skip()` method in the cursor is simplified by delegating to the existing `scroll()` method. **New feature: Table metadata querying** - Added a `tables()` method to the `Cursor` class, enabling users to retrieve information about tables with support for filtering by table name (including temporary tables), schema, catalog, and table type (supports both string and list input). The method returns the cursor itself for easy chaining and iteration. **Testing improvements** - Introduced a suite of tests for the new `tables()` method, covering basic usage, filtering by name, schema, and type, wildcard support, combined filters, empty results, iteration, method chaining, and existence checks. These tests ensure the method works as intended and handles edge cases. **Code simplification** - Refactored the `skip()` method in the cursor to delegate to the `scroll()` method in 'relative' mode, removing redundant validation and manual row skipping logic. --------- Co-authored-by: Jahnvi Thakkar <jathakkar@microsoft.com>

### Work Item / Issue Reference   > [AB#34893](https://sqlclientdrivers.visualstudio.com/c6d89619-62de-46a0-8b46-70b92a84d85e/_workitems/edit/34893) ------------------------------------------------------------------- ### Summary This pull request adds comprehensive support for capturing and managing diagnostic messages (such as SQL Server PRINT statements and warnings) in the `mssql_python` driver's `Cursor` class, following the DBAPI specification. It introduces a new `messages` attribute on the cursor, ensures messages are cleared or preserved at the correct times, and provides robust testing for these behaviors. Additionally, it implements the underlying C++ binding for retrieving all diagnostic records from the ODBC driver. **Diagnostic message handling improvements:** * Added a `messages` attribute to the `Cursor` class to store diagnostic messages, and ensured it is cleared before each non-fetch operation (e.g., `execute`, `executemany`, `close`, `commit`, `rollback`, `scroll`, and `nextset`) to comply with DBAPI expectations. (`mssql_python/cursor.py`) * After each statement execution and fetch operation, diagnostic messages (including informational and warning messages) are collected and appended to the `messages` list, using a new C++ binding. (`mssql_python/cursor.py`, `mssql_python/pybind/ddbc_bindings.cpp`) **Native driver and binding enhancements:** * Implemented the `SQLGetAllDiagRecords` function in the C++ pybind layer to retrieve all diagnostic records from an ODBC statement handle, handling both Windows and Unix platforms, and exposed it as `DDBCSQLGetAllDiagRecords` to Python. (`mssql_python/pybind/ddbc_bindings.cpp`) **Testing and specification compliance:** * Added a comprehensive test suite to verify message capturing, clearing, preservation across fetches, handling of multiple messages, message formatting, warning capture, manual clearing, and error scenarios, ensuring compliance with DBAPI and robust behavior. (`tests/test_004_cursor.py`) **Other cursor improvements:** * Refactored the `skip` method to validate arguments more strictly, clear messages before skipping, and improve error handling and documentation. (`mssql_python/cursor.py`) These changes significantly improve the usability and correctness of message handling in the driver, making it easier for users to access and manage SQL Server informational and warning messages in Python applications. --------- Co-authored-by: Jahnvi Thakkar <jathakkar@microsoft.com>

This improves usability for developers working with the cursor API. Transaction management enhancements: * Added a `commit` method to the `Cursor` class, allowing users to commit transactions directly from the cursor. This delegates to the underlying connection's `commit` method and provides error handling if the cursor is closed. * Added a `rollback` method to the `Cursor` class, allowing users to roll back transactions directly from the cursor. This delegates to the underlying connection's `rollback` method and provides error handling if the cursor is closed. --------- Co-authored-by: Jahnvi Thakkar <jathakkar@microsoft.com>

Comprehensive tests have been added to ensure its correctness, robustness, and compatibility with various SQL scenarios and data types. Addition of `fetchval` method: * Added `fetchval` to the `Cursor` class in `mssql_python/cursor.py`, allowing users to easily fetch the first column of the first row from a query result. This is especially useful for aggregate queries or scalar selects and supports method chaining. Testing and validation of `fetchval`: * Extensive tests added in `tests/test_004_cursor.py` to validate `fetchval` for basic functionality, multiple data types, NULL values, empty results, multiple columns/rows, aggregate functions, method chaining, closed cursor behavior, rownumber tracking, error scenarios, and common performance patterns. These changes make it easier and safer for users to retrieve single values from queries, improving developer experience and reliability. --------- Co-authored-by: Jahnvi Thakkar <jathakkar@microsoft.com>

It includes full implementation, integration with fetch methods, and comprehensive tests to verify the new functionality and its logging behavior. ### Feature Addition: Cursor Row Number Tracking * Added the `rownumber` property to the `Cursor` class, which returns the current 0-based index in the result set or `None` if unavailable. This property logs a warning when accessed, as it's a DB-API extension and may not be portable. Supporting methods for managing rownumber state (`_reset_rownumber`, `_increment_rownumber`, `_decrement_rownumber`, `_clear_rownumber`) were also introduced. * Integrated rownumber management into cursor operations: reset/clear on `execute`, increment on successful fetches in `fetchone`, `fetchmany`, and `fetchall`. ### Testing Enhancements * Added new tests in `tests/test_004_cursor.py` to verify basic rownumber functionality, correct progression during fetch operations, warning logging behavior, and correct handling when the cursor is closed. These changes provide users with a convenient way to track cursor position in result sets and ensure the feature is robustly tested and logged. --------- Co-authored-by: Jahnvi Thakkar <jathakkar@microsoft.com>

### Work Item / Issue Reference   > [AB#33395](https://sqlclientdrivers.visualstudio.com/c6d89619-62de-46a0-8b46-70b92a84d85e/_workitems/edit/33395)  > GitHub Issue: #<ISSUE_NUMBER> ------------------------------------------------------------------- ### Summary  This pull request focuses on improving type safety and error handling for parameter binding and execution in the MSSQL Python driver, especially for string and binary types. The changes ensure that only supported Python types are bound to SQL parameters and that errors are raised for unsupported types, preventing silent failures. Additionally, the data-at-execution (DAE) streaming path for strings is now more robust and explicit. **Parameter type safety and error handling:** * Changed `_map_sql_type` in `cursor.py` to raise a `TypeError` for unsupported parameter types instead of defaulting to `SQL_VARCHAR`, preventing silent type mismatches. * In `ddbc_bindings.cpp`, added explicit type checks for `SQL_C_CHAR` and `SQL_C_BINARY` bindings, raising an error if the Python object is not a string or bytes-like object. **DAE (Data At Execution) streaming improvements:** * Enhanced the DAE streaming logic for `SQL_C_CHAR` in `ddbc_bindings.cpp` to handle string parameters more robustly, including chunked streaming via `SQLPutData`. * Added support for chunked DAE streaming of Python `str` objects mapped to `SQL_C_CHAR`, ensuring large strings are sent in manageable pieces. **Platform-specific encoding for wide strings:** * Ensured that wide string (`SQL_C_WCHAR`) parameters are correctly converted to the platform-specific encoding before streaming.

The main change is broadening the omission list to exclude additional top-level files from coverage reports. Coverage configuration updates: * Added `main.py`, `setup.py`, `bcp_options.py`, and `testing_ddbc_bindings.py` to the omit list in `.coveragerc`, ensuring these files are not included in coverage calculations.

### Work Item / Issue Reference   > AB#<WORK_ITEM_ID>  > GitHub Issue: #182 ------------------------------------------------------------------- ### Summary  This pull request makes improvements to the cursor resource management and error handling in the `mssql_python/cursor.py` module. The main changes include making the cursor close operation idempotent, refining exception types, and improving logging during cleanup. These updates help ensure more robust and predictable behavior when working with cursors. Error handling improvements: * Changed the exception raised when attempting to close an already closed cursor from a generic `Exception` to a more specific `ProgrammingError`, providing clearer feedback to users. * Updated the import statement to use `ProgrammingError` instead of `InterfaceError`, aligning with the new error handling approach. Resource cleanup and logging: * Improved the destructor (`__del__`) to check for the correct `closed` attribute and made sure no exception is raised if the cursor is already closed, enhancing reliability during garbage collection. * Changed the logging level in the destructor from 'error' to 'debug' for exceptions during cleanup, reducing unnecessary noise in error logs.

### Work Item / Issue Reference   > AB#<WORK_ITEM_ID>  > GitHub Issue: #205 ------------------------------------------------------------------- ### Summary  This pull request improves the handling of empty string and binary values in the MSSQL Python bindings, ensuring that empty data is correctly distinguished from NULL values and does not cause assertion failures. It also adds comprehensive tests to verify correct behavior for these edge cases. **Improvements to empty value handling:** * Updated `SQLGetData_wrap` in `ddbc_bindings.cpp` to append an empty string (`""`) or empty bytes (`b""`) when the returned data length is zero, instead of causing assertion failures or misinterpreting the value as NULL. This change applies to both string and binary column types.

It also significantly expands the test suite to cover these scenarios and documents current driver limitations regarding parameter and fetch buffer sizes. **Binary Data Handling Improvements** * Updated `_map_sql_type` in `cursor.py` to always use `VARBINARY` for Python `bytes`/`bytearray`, avoiding storage waste and ensuring correct handling of variable-length data. This removes previous logic that sometimes used fixed-length `BINARY` and simplifies type mapping. * Improved sample value selection in `_select_best_sample_value` to correctly handle columns that contain only binary types (`bytes` or `bytearray`). **Test Suite Enhancements for Binary Data** * Fixed and clarified the `test_longvarbinary` test to expect the correct number of rows and removed assumptions about zero-padding in returned binary data. * Added new tests covering edge cases: - Executemany with binary data and empty byte arrays, ensuring correct insertion and retrieval of empty, regular, and null binary values. - Binary data over 8000 bytes, documenting driver limitations (8192 bytes for parameters, 4096 bytes for fetch buffer) and verifying correct error handling and data retrieval for supported sizes. - All empty binaries: verifies that multiple empty binary rows are handled and returned as zero-length `bytes`. - Mixing `bytes` and `bytearray` types in the same column, confirming consistent storage and retrieval as `bytes`. - Binary columns with mostly small/empty values and one large value, ensuring the large value is handled within driver limits. - Table with only NULL and empty binary values, verifying clear distinction between NULL and empty values and correct query results.
