Summary of Changes
Hello @hiyuchang, I'm Gemini Code Assist1! 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 addresses a critical bug in the file_reader.py module where task arguments derived from self.meta were being passed by reference. By implementing deep copies of these arguments, the change prevents unintended modifications to the original meta object when tasks are processed or split, thereby ensuring data integrity and predictable behavior.
Highlights
- Bug Fix: Data Integrity: The primary issue of
meta.argsbeing unintentionally modified when tasks are split is resolved by ensuring that arguments passed to newTaskobjects are independent copies. - Dependency Update: The
copymodule has been imported intrinity/buffer/reader/file_reader.pyto enable deep copying functionality. - Argument Handling: The
readmethod infile_reader.pynow explicitly usescopy.deepcopy()forformat_args,rollout_args,workflow_args, andreward_fn_argswhen constructingTaskobjects, preventing side effects on the originalself.metaobject.

Code Review
This pull request fixes a critical bug where shared configuration objects (meta.args) were being mutated during task processing, leading to unpredictable behavior. The fix involves creating deep copies of task-specific arguments when instantiating a Task, effectively isolating the state of each task. The change is correct and addresses the root cause. I've added one suggestion for a minor performance optimization by using a mix of shallow and deep copies where appropriate, but the current implementation is safe and clear.
