## Summary of Changes Hello @claudevdm, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request enhances the Apache Beam Python SDK by introducing a robust mechanism for managing `PipelineOptions` in concurrent environments. By leveraging Python's `contextvars`, it ensures that pipeline options are correctly isolated and accessible in a thread-safe and async-safe manner throughout the pipeline's construction and execution lifecycle. This change addresses potential race conditions and improves the reliability of option retrieval within complex pipeline definitions and transformations. ### Highlights * **Introduction of Context-Scoped Pipeline Options**: A new module `pipeline_construction_options.py` is added to provide thread-safe and async-safe access to `PipelineOptions` using Python's `contextvars`. * **scoped_pipeline_options Context Manager**: A context manager is introduced to set and manage `PipelineOptions` for the duration of a code block, ensuring proper restoration of previous options in nested scenarios. * **Integration with Pipeline.run() and Pipeline.apply()**: The `Pipeline.run()` and `Pipeline.apply()` methods are updated to utilize the new `scoped_pipeline_options` context manager, making pipeline options accessible during both pipeline construction and execution phases. * **Comprehensive Testing**: Extensive unit tests are added to `pipeline_construction_options_test.py` to validate the correct isolation of pipeline options across threads and asyncio tasks, as well as proper behavior in nested scopes and during transform expansion and coder proto conversion. 🧠**New Feature in Public Preview:** You can now enable **Memory** to help **Gemini Code Assist** learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. **Click [here](https://codeassist.google/code-review/login) to enable Memory in your admin console.** <details> <summary><b>Changelog</b></summary> * **sdks/python/apache_beam/options/pipeline_construction_options.py** * Added a new module to provide context-scoped access to `PipelineOptions`. * Introduced `_current_pipeline_options` as a `ContextVar` to store options. * Implemented `get_current_pipeline_options()` to retrieve the current options. * Implemented `scoped_pipeline_options()` as a context manager for setting options. * **sdks/python/apache_beam/options/pipeline_construction_options_test.py** * Added a new test file to verify the functionality of `pipeline_construction_options`. * Included tests for nested scoping, exception handling, thread isolation, and asyncio task isolation. * Added tests to confirm that transforms and coders can correctly access pipeline options during their respective phases. * **sdks/python/apache_beam/pipeline.py** * Imported `scoped_pipeline_options` from the new module. * Refactored `Pipeline.run()` to wrap its logic in `scoped_pipeline_options(self._options)` and delegate to a new `_run_internal()` method. * Refactored `Pipeline.apply()` to wrap its logic in `scoped_pipeline_options(self._options)` and delegate to a new `_apply_internal()` method. </details> <details> <summary><b>Activity</b></summary> * The pull request was created by claudevdm. * No human activity (comments, reviews, or progress updates) has been recorded on this pull request yet. </details> <details> <summary><b>Using Gemini Code Assist</b></summary> <br> The full guide for Gemini Code Assist can be found on our [documentation page](https://developers.google.com/gemini-code-assist/docs/review-github-code), here are some quick tips. <b>Invoking Gemini</b> You can request assistance from Gemini at any point by creating a comment using either `/gemini <command>` or `@gemini-code-assist <command>`.
