Work Item / Issue Reference

GitHub Issue: #148

Summary

This PR updates the PR validation workflow, documentation, and PR template to support a more inclusive contribution process that accommodates both Microsoft organization members and external contributors with appropriate validation requirements.

🔧 Workflow Updates (`.github/workflows/pr-format-check.yml`)

Added organization membership detection: Uses GitHub API to check if PR author is a Microsoft org member
Dual validation logic:
- Microsoft org members: Continue to require ADO Work Item links (maintains existing behavior)
- External contributors: Require GitHub issue links in format https://github.com/microsoft/mssql-python/issues/XXX
Preserved existing validations: Title prefix and summary requirements remain enforced for all contributors
Enhanced error messages: Provide clear, actionable guidance with references to CONTRIBUTING.md

📚 Documentation Updates (`CONTRIBUTING.md`)

Clear contributor guidance: Step-by-step instructions for both internal and external contributors
External contributor workflow:
1. Create GitHub issue first
2. Link issue in PR description
3. Follow PR title and summary requirements
Internal contributor workflow: Clarified ADO Work Item requirements
Comprehensive PR requirements: Documented all validation rules in one place

📝 PR Template Updates (`.github/PULL_REQUEST_TEMPLATE.MD`)

Dual-purpose template: Sections for both ADO links and GitHub issue links
Clear guidance: Comments explaining which section to use based on contributor type
Examples provided: Specific format examples for both link types
Embedded guidelines: Quick reference for contribution requirements

Technical Implementation

Validation Logic

Microsoft members: Validates ADO links with pattern /https:\/\/sqlclientdrivers\.visualstudio\.com\/[^\/]+\/_workitems\/edit\/\d+/i
External contributors: Validates GitHub issue links with pattern /https:\/\/github\.com\/microsoft\/mssql-python\/issues\/\d+/i

Benefits

✅ Seamless external contribution: Clear path for community contributors
✅ Maintained internal traceability: ADO Work Item requirements preserved
✅ Backward compatibility: No changes for existing internal workflows
✅ Clear documentation: Comprehensive guidance for all contributor types
✅ Actionable error messages: Helpful validation failures with next steps

Validation

✅ YAML syntax validated and confirmed working
✅ Workflow logic reviewed for edge cases and error handling
✅ Regex patterns tested for both ADO and GitHub issue links
✅ Error messages verified for clarity and actionability
✅ Documentation reviewed for completeness and accuracy

This implementation ensures that external contributors can easily participate in the project while maintaining the required traceability and validation standards for internal Microsoft contributors.

This pull request was created as a result of the following prompt from Copilot chat.

Update the PR validation workflow, documentation, and PR template to support a more inclusive contribution process:

In .github/workflows/pr-format-check.yml:

For PRs from microsoft org members, continue to require an ADO Work Item link in the PR description.

For PRs from external contributors, require a GitHub issue link (format: https://github.com/microsoft/mssql-python/issues/XXX) in the PR description instead of an ADO Work Item link.

Ensure that the title prefix and summary requirements remain enforced for all contributors.

In CONTRIBUTING.md:

Add clear instructions for external contributors: they must first raise a GitHub issue and then link it in their PR description.

Clarify that internal contributors (microsoft org) must link an ADO Work Item.

In .github/PULL_REQUEST_TEMPLATE.MD:

Provide guidance for both contributor types (internal: ADO link; external: GitHub issue link).

Make the requirements and examples explicit.

All changes should make the process as seamless as possible for external contributors while maintaining the required traceability for internal contributors.

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.

Instead of downloading a pre-built pipeline artifact, it now downloads the appropriate Python ARM64 NuGet package, extracts the required `.lib` files, and validates their presence. This change makes the build process more self-contained and less dependent on internal artifacts. **Build pipeline changes:** * Replaced the `DownloadPipelineArtifact@2` task with a PowerShell script that downloads the correct Python ARM64 NuGet package based on the specified Python version, extracts its contents, and copies the required `.lib` files to the target directory. * The script includes validation to ensure the expected `.lib` file is present and provides cleanup for temporary files and directories. **Process improvement:** * The build is now independent of internal pipeline artifacts and relies on public NuGet packages, improving reliability and maintainability. --------- Co-authored-by: David Engel <[email protected]> Co-authored-by: MerlinBot <MerlinBot> Co-authored-by: Saurabh Singh (SQL Drivers) <[email protected]>

ARM64 ODBC Package Issue: • The ARM64 ODBC driver package (msodbcsql18_18.5.1.1-1_arm64.apk) contains arch = x86_64 in .PKGINFO. • This is causing installation failures on newer Alpine versions where architecture validation is enforced. • Local Docker testing confirmed that Alpine 3.22 installs the package successfully. 2. Compiler Warning Issue on Alpine: • The CI also fails with alpine :latest due to a new compiler warning in std::wstring_convert (_GLIBCXX17_DEPRECATED) which is treated as an error. • The current fix for this warning relies on Alpine 3.22, so we have pinned x86_64 CI to 3.22 too for now. 3. Temporary CI Fix: • Both ARM64 and x86_64 CI jobs are now pinned to Alpine 3.22. • This unblocks all pipelines while maintaining consistency across architectures. 4. We'll track ODBC team’s fix for ARM64 package and once fixed, we can safely move Alpine CI back to alpine:latest. Also, we have a proper fix for the compiler warning to allow CI to eventually move back to latest.

The main changes include stricter validation and enforcement of encoding rules for SQL_WCHAR types, making encoding/decoding settings thread-safe, and updating cursor methods to consistently use these settings. This ensures correct handling of Unicode data, prevents ambiguous encoding scenarios, and improves reliability in multi-threaded environments. **Encoding and Decoding Validation & Enforcement** * Enforced strict validation so that only `'utf-16le'` and `'utf-16be'` encodings are accepted for SQL_WCHAR, explicitly rejecting `'utf-16'` with BOM due to byte order ambiguity. Programming errors are raised if invalid encodings are used, both in `setencoding` and `setdecoding` methods. * Added validation to ensure encoding names only contain safe characters and are of reasonable length, preventing security issues and denial-of-service attacks. **Thread Safety** * Introduced a re-entrant lock (`_encoding_lock`) to protect encoding and decoding settings, making `setencoding`, `setdecoding`, `getencoding`, and `getdecoding` thread-safe and preventing race conditions. **Cursor Integration** * Updated cursor methods (`execute`, `executemany`, `fetchone`, `fetchmany`, `fetchall`) to retrieve encoding and decoding settings from the connection and pass them to low-level bindings, ensuring consistent Unicode handling throughout query execution and result fetching **Error Handling and Logging** * Improved error handling in cursor encoding/decoding retrieval, logging warnings if settings cannot be accessed due to database errors and falling back to safe defaults. **Bindings Interface Update** * Updated the C++ binding for parameter encoding to accept an explicit encoding argument, supporting the new encoding flow from Python.

The main improvement is moving the logic for setting the query timeout from the `execute` method to the cursor initialization process, ensuring the timeout is consistently applied whenever the statement handle is allocated or reset. Statement handle timeout management: * Introduced a new `_set_timeout` method to set the query timeout attribute on the statement handle during cursor initialization, following best practices for performance. (`mssql_python/cursor.py`) * Removed redundant timeout-setting logic from the `execute` method, centralizing timeout management in the cursor lifecycle. (`mssql_python/cursor.py`)

The main change is that the function now removes `Trusted_Connection` instead of `Encrypt` and `TrustServerCertificate`, and the corresponding test has been updated to reflect this new behavior. Sensitive parameter filtering update: * In `mssql_python/auth.py`, the `remove_sensitive_params` function now excludes `trusted_connection` instead of `encrypt` and `trustservercertificate` when filtering parameters. Test updates for new filtering logic: * In `tests/test_008_auth.py`, the test for `remove_sensitive_params` has been updated to expect that `Encrypt` and `TrustServerCertificate` are no longer removed, while `Trusted_Connection` is now excluded.

The pipeline clones the GitHub repository, creates a timestamped sync branch, resets it to match the GitHub `main` exactly, pushes it to Azure DevOps, and opens a pull request for review. This ensures the internal repository stays up-to-date with the public source. Key additions in the new pipeline: **Pipeline Automation for GitHub-to-ADO Sync** * Added a new pipeline file `OneBranchPipelines/github-ado-sync.yml` to automate daily sync from GitHub to Azure DevOps, scheduled at 5pm IST. * The pipeline clones the public GitHub repository, creates a timestamped sync branch based on the latest Azure DevOps `main`, and resets it to match GitHub's `main` branch exactly. * Automates pushing the sync branch to Azure DevOps and creates a pull request targeting `main`, including reviewer assignment and clean-up steps.

The main change is replacing hardcoded usernames and passwords with `Trusted_Connection=yes` in all connection strings, and in some cases, using environment variables for server and database names. This prevents the exposure of credentials and avoids related security warnings. **Test connection string improvements:** * Replaced all hardcoded `UID` and `PWD` parameters in connection strings with `Trusted_Connection=yes` in `tests/test_002_types.py`, `tests/test_013_sqlwchar_conversions.py`, and `tests/test_014_ddbc_bindings_coverage.py`, enhancing security and aligning with best practices.

The pipeline changes simplify the sync process and improve conflict handling, while the codebase changes mostly involve formatting for better readability and maintainability. **Azure DevOps Pipeline Improvements:** - Simplified the sync process by checking out the repository directly (`checkout: self`) and removing redundant clone and remote-add steps. The pipeline now adds the GitHub remote and fetches the main branch in a single step. - Improved branch creation and sync logic: now creates the sync branch directly from the current state and pulls from GitHub main, handling merge conflicts by always accepting the GitHub version as the source of truth. - Changed the push target from the previous Azure DevOps remote to the default `origin` remote, aligning with the new checkout approach. - Cleaned up unnecessary `workingDirectory` specifications after refactoring the pipeline steps. **C++ Code Formatting and Readability:** - Reformatted function calls and object constructions in `connection.cpp` and `connection_pool.cpp` to improve readability, especially for multi-argument lines.

### Work Item / Issue Reference   > AB#<WORK_ITEM_ID>  > GitHub Issue: #318 ------------------------------------------------------------------- ### Summary  This pull request introduces improvements to the handling of string encoding in the `getinfo` method for SQL Server connections, adds support for profiling builds in the Windows build script, and enhances test coverage for string decoding. The most important changes are grouped below: ### String Decoding Improvements * The `getinfo` method in `connection.py` now attempts to decode string results from SQL Server using multiple encodings in order: UTF-16LE (Windows default), UTF-8, and Latin-1. This improves robustness when handling driver responses and avoids silent data corruption by returning `None` if all decoding attempts fail. ### Test Coverage * Added a new test `test_getinfo_string_encoding_utf16` in `test_003_connection.py` to verify that string values returned by `getinfo` are properly decoded from UTF-16, contain no null bytes, and are non-empty, helping catch encoding mismatches early. ### Build Script Cleanup * Removed redundant logic from `build.bat` related to copying the `msvcp140.dll` redistributable, simplifying the post-build process.

The main changes include reducing iteration counts and timeouts for faster test runs, and consolidating several similar tests into a single parameterized test using `pytest.mark.parametrize`.

The default `paramstyle` is now set to `pyformat`, and both `execute` and `executemany` methods have been updated to automatically detect and convert parameter styles as needed. A new utility module, `parameter_helper.py`, has been added to handle parameter style parsing and conversion. **Parameter style support and conversion:** * Changed the global `paramstyle` in `mssql_python/__init__.py` from `"qmark"` to `"pyformat"`, making `pyformat` the default parameter style. * Added a new module `mssql_python/parameter_helper.py` containing helper functions to parse pyformat parameters, convert pyformat SQL to qmark style, and auto-detect/convert parameter styles in queries. **Enhancements to parameter handling in cursor methods:** * Updated the `execute` method in `mssql_python/cursor.py` to auto-detect and convert parameter styles, supporting both single values and various parameter formats, and to use the new helper functions for conversion. * Refactored parameter flattening logic in `execute` to rely on the new auto-detection and conversion, removing the old manual flattening. * Enhanced the `executemany` method in `mssql_python/cursor.py` to auto-detect parameter style, convert pyformat to qmark for all rows if needed, and wrap single parameters for backward compatibility. **Tests and validation:** * Updated the `test_paramstyle` test in `tests/test_001_globals.py` to expect the new default `paramstyle` value of `"pyformat"`.

Comprehensive tests have been added to ensure correct behavior of this property under various scenarios, improving reliability and clarity for users of the connection API. **Connection class enhancements:** * Added a `closed` property to the connection class, which returns `True` if `close()` was called, and `False` otherwise. This property does not indicate connection health, only whether `close()` was explicitly invoked. **Test coverage improvements:** * Added tests to verify the `closed` property reflects the connection state before and after calling `close()`. * Added tests to confirm that calling `close()` multiple times is safe and the `closed` property remains `True` (idempotency). * Added tests to check the `closed` property when using the connection as a context manager, ensuring it is `True` after exiting the block. * Added tests to verify that operations on a closed connection raise appropriate exceptions, and the `closed` property accurately reflects the closed state.
