Walkthrough

The changes in this pull request focus on the execute_task_with_cache function located in the executorlib/interactive/shared.py file. The primary modification involves how the resource_dict is accessed during serialization for caching. The code now uses the .get() method to retrieve resource_dict from task_dict, providing a default empty dictionary if it is not found. This adjustment aims to prevent KeyError exceptions and improve the function's robustness.

Changes

File Path Change Summary
executorlib/interactive/shared.py Modified execute_task_with_cache to use task_dict.get("resource_dict", {}) for accessing resource_dict, preventing potential KeyError.

🐇 In the code we now see,
A fallback for you and me,
If resource_dict is not in sight,
An empty one will make it right!
So tasks can run without a hitch,
A small fix, but quite the pitch!

    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.

596-596: Consider adding docstring for _execute_task_with_cache.

The function lacks a docstring that would document the optional nature of resource_dict. Consider adding one to improve code maintainability.

Add this docstring above the function:

def _execute_task_with_cache(
    interface: SocketInterface,
    task_dict: dict,
    future_queue: queue.Queue,
    cache_directory: str,
):
    """
    Execute the task with caching support.

    Args:
        interface (SocketInterface): Socket interface for zmq communication
        task_dict (dict): Task dictionary containing:
            - fn (callable): Function to execute
            - args (tuple): Function arguments
            - kwargs (dict): Function keyword arguments
            - resource_dict (dict, optional): Resource configuration. Defaults to {}.
        future_queue (queue.Queue): Queue for receiving new tasks
        cache_directory (str): Directory to store cache files
    """

596-596: LGTM! Safer dictionary access pattern.

The change to use dict.get() with a default empty dictionary is a good defensive programming practice. This prevents potential KeyError exceptions when resource_dict is not present in task_dict.


596-596: Verify consistent handling of resource_dict across the codebase.

Let's ensure this change maintains consistency with how resource_dict is handled in other parts of the codebase.

✅ Verification successful

Based on the search results, I can now generate the final response:

Making resource_dict optional is safe and consistent with codebase usage

The codebase shows a clear pattern of safe resource dictionary handling:

  • All direct dictionary access (resource_dict[key]) occurs after proper validation through check_resource_dict() or in contexts where the dictionary is explicitly populated
  • The codebase includes dedicated validation functions (check_resource_dict, check_resource_dict_is_empty) to ensure proper dictionary state
  • No unsafe .get() patterns were found, indicating careful dictionary access
🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Check how resource_dict is accessed across the codebase
# Test 1: Find all direct dictionary access patterns for resource_dict
echo "Test 1: Direct dictionary access patterns:"
rg "resource_dict\[" --type py

# Test 2: Find all dict.get() access patterns for resource_dict
echo "Test 2: Safe dictionary access patterns:"
rg "resource_dict\.get\(" --type py

# Test 3: Find all places where resource_dict is validated or checked
echo "Test 3: Resource dict validation:"
rg "check_resource_dict" --type py
