Description

This PR implements the missing transaction_manager.py module in the analyzers directory. The module is critical for managing code modifications and transactions during analysis.

Implementation Details

  1. Created transactions.py module with transaction classes:

    • Base Transaction class
    • EditTransaction, InsertTransaction, RemoveTransaction
    • FileAddTransaction, FileRenameTransaction, FileRemoveTransaction
    • Supporting classes like ChangeType, DiffLite, and TransactionPriority

  2. Implemented transaction_manager.py with the following features:

    • Transaction queuing and sorting
    • Transaction limits and timing controls
    • Conflict resolution
    • Bulk commit functionality
    • Undo support

  3. Added comprehensive tests in test_transaction_manager.py

  4. Updated the README.md with documentation on how to use the transaction manager

Fixes

This implementation addresses the following issues mentioned in ZAM-367:

  • Inability to properly track and manage code modifications during analysis
  • Lack of transaction limits and timing controls for analysis operations
  • Potential for inconsistent state when multiple analyzers attempt to modify code
  • Missing undo functionality for reverting changes

Testing

The implementation includes comprehensive unit tests that cover:

  • Transaction creation and management
  • Transaction limits and timing
  • Conflict resolution
  • Committing transactions
  • Reverting transactions

Closes ZAM-367

Summary by Sourcery

Implement a transaction management framework in the analyzers package by adding transaction_manager.py and transactions.py, update documentation with usage instructions, and provide tests to verify transaction behavior

New Features:

  • Add TransactionManager in the analyzers package to queue, sort, limit, resolve conflicts, bulk commit, and undo code modification transactions
  • Introduce a transactions module defining base Transaction and specialized types: EditTransaction, InsertTransaction, RemoveTransaction, FileAddTransaction, FileRenameTransaction, and FileRemoveTransaction

Documentation:

  • Update analyzers/README.md with documentation and usage examples for the new transaction manager

Tests:

  • Add comprehensive unit tests in test_transaction_manager.py covering transaction creation, sorting, limits, conflict resolution, commit/apply/revert, and file operations

Description by Korbit AI

What change is being made?

Implement a transaction_manager.py module in the analyzers directory to handle code modifications during analysis by managing transactions like edits, inserts, and file operations.

Why are these changes being made?

These changes introduce a structured way to manage code modifications during analysis, essential for tasks such as code refactoring or validations. By handling transactions such as queuing, sorting, and committing in a controlled manner, the new module improves the overall efficiency and reliability of the code analysis process. The added test suite ensures robustness and correctness of the implemented features.

✅ Fixed the failing mypy checks in PR #107. The issues were:

  1. In InsertTransaction class:

    • Fixed type errors in _generate_new_content_bytes() by adding a null check for new_content
    • Fixed type errors in diff_str() by safely handling the case when new_content is None

  2. In TransactionManager class:

    • Added proper type annotations for session dictionary
    • Fixed type issues with stopwatch_start by properly annotating it as Optional[float]
    • Added null checks for stopwatch_start in the is_time_exceeded() method
    • Added proper type annotations for collections in get_transactions_at_range() and _get_conflicts()

The changes have been pushed to the original PR branch in this commit.

✅ Fixed the failing pre-commit checks in PR #107. The issues were:

  1. In transaction_manager.py:

    • Reduced complexity of the _resolve_conflicts method by extracting logic into separate methods
    • Fixed type annotations for collections (List, Dict) to use proper imports
    • Fixed nested if statements in get_transactions_at_range
    • Fixed try-except block to use else clause properly
    • Fixed redundant exception object in logging.exception call

  2. In transactions.py:

    • Fixed type errors in InsertTransaction class by adding proper null checks
