Summary

Addresses all outstanding Gemini Code Assist review feedback from PRs #1, #2, and #3.

High priority fixes

  • SubprocessPlugin kwargs passthrough: _which_interceptor now passes **kwargs (mode, path) to _handle_which instead of silently dropping them
  • SubprocessPlugin string command handling: _handle_run raises TypeError on string commands instead of silently splitting into characters ("ls" -> ['l', 's'])

Medium priority fixes

  • Idiomatic next() lookups: Replaced loop-and-break plugin lookup patterns with next() expressions in subprocess, popen, and proxy code
  • Deduplicated _BigfootModule context manager: Extracted _push_cm() helper to eliminate duplicated sandbox creation logic in __enter__ and __aenter__

Already addressed (no changes needed)

Version bump

0.10.1

Test plan

  • python -m pytest tests/ examples/ -x -q -- 773 passed
  • ruff check src/ tests/ examples/ -- clean

- SubprocessPlugin: pass **kwargs through _which_interceptor to
  _handle_which (shutil.which mode/path args were silently dropped)
- SubprocessPlugin: raise TypeError on string commands in _handle_run
  instead of silently splitting into characters
- Replace loop-and-break plugin lookups with idiomatic next() in
  subprocess, popen, and proxy code
- Extract _push_cm() helper in _BigfootModule to deduplicate
  __enter__/__aenter__ sandbox creation logic

Bump version to 0.10.1.

Summary of Changes

Hello, 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 several pieces of feedback from previous code reviews, focusing on improving the robustness, clarity, and idiomatic nature of the bigfoot library. Key changes include enhancing argument handling for subprocess commands, introducing more explicit error reporting for incorrect command formats, and refactoring internal plugin lookup mechanisms and context manager creation for better maintainability and readability.

Highlights

  • SubprocessPlugin kwargs passthrough: _which_interceptor now correctly passes **kwargs (mode, path) to _handle_which, preventing silent dropping of arguments.
  • SubprocessPlugin string command handling: _handle_run now raises a TypeError when a string command is provided, instead of silently splitting it into characters, improving error detection.
  • Idiomatic next() lookups: Replaced imperative loop-and-break patterns with more Pythonic next() expressions for plugin lookups across subprocess, popen, and proxy code.
  • Deduplicated _BigfootModule context manager: Extracted a _push_cm() helper method to centralize and eliminate duplicated sandbox creation logic in __enter__ and __aenter__ methods.

Code Review

This pull request addresses several pieces of feedback, improving code quality and fixing bugs. The changes include using more idiomatic Python constructs like next() for lookups, refactoring duplicated code into a helper function, and adding robustness to the SubprocessPlugin by handling string commands and passing through keyword arguments. My review includes one suggestion to further improve the SubprocessPlugin by recording the passed-through keyword arguments to allow for more precise test assertions.

While it's great that **kwargs are now passed through from the interceptor, they are currently ignored in this handler. This could lead to subtle bugs in tests where arguments like path are expected to influence the behavior of shutil.which.

To make this mock more robust, I suggest recording these kwargs in the interaction details. This would make the mock's behavior more transparent and allow tests to assert that which was called with specific options.

You would need to update the details creation in this function, and then update assertable_fields to include "kwargs" for which interactions.

For example:

# In _handle_which
details = {"name": name, "returns": config.returns, "kwargs": kwargs}

# In assertable_fields
if interaction.source_id == _SOURCE_WHICH:
    return frozenset({"name", "returns", "kwargs"})

- Add explicit type annotations to avoid Returning Any errors
- Remove unused type: ignore comments
- Add import-untyped ignores for psycopg2 and asyncpg (no stubs available)
- Add assignment ignores for aiohttp URL vs str type mismatch

Re: Gemini's suggestion to record **kwargs in _handle_which interactions -- good catch. Since bigfoot enforces full-assertion-certainty (every field in details becomes a required assertion field), adding mode/path here would be a breaking change for existing tests. Will track as a separate enhancement.
