Important

Review skipped

Review was skipped due to path filters

⛔ Files ignored due to path filters (1)
  • Lib/test/test_resource.py is excluded by !Lib/**

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.

📝 Walkthrough

Walkthrough

This PR refactors resource limit Python bindings from accepting i32 resource identifiers to PyIntRef. A new py2rlim helper validates Python integers, rejecting negatives and mapping overflows to Python exceptions. Both getrlimit and setrlimit functions are updated to use the new type and conversion logic.

Changes

Resource Parameter Type Migration

Layer / File(s) Summary
Module Imports
crates/stdlib/src/resource.rs		 PyIntRef is added to support Python integer resource identifiers.
Conversion Helper and Type Implementations
crates/stdlib/src/resource.rs		 py2rlim helper converts PyIntRef to libc::rlim_t, rejecting negatives and mapping conversion errors to Python ValueError/OverflowError. Limits ToPyObject implementation is repositioned.
Function Updates
crates/stdlib/src/resource.rs		 getrlimit and setrlimit are updated to accept PyIntRef, use py2rlim for conversion, validate against RLIM_NLIMITS, and call libc functions with converted resource IDs.

Estimated code review effort

Poem

🐰 Resource limits once held i32 fast,
Now PyIntRef lets validation last!
Negatives rejected, overflows caught with care,
The conversion dance flows through the air. ✨

❌ Failed checks (2 warnings)

Check name Status Explanation Resolution
Title check ⚠️ Warning The PR title claims to update 'test_resource.py' to version 3.14.4, but the actual changes are to 'crates/stdlib/src/resource.rs' with significant signature updates to getrlimit and setrlimit functions. Update the title to accurately reflect the main changes, such as 'Update resource stdlib bindings to accept PyIntRef' or similar, to match the actual changeset.
Docstring Coverage ⚠️ Warning Docstring coverage is 50.00% which is insufficient. The required threshold is 80.00%. Write docstrings for the functions missing them to satisfy the coverage threshold.
