Update stat from 3.13.5 by ShaharNaveh · Pull Request #5992 · RustPython/RustPython

ShaharNaveh

Walkthrough

The change introduces platform-specific conditional compilation for the S_IFWHT constant in the stat module, assigning it the value 0o160000 on macOS and 0 on other platforms. This aligns the constant's value with macOS's definition for whiteout file types.

Changes

File(s) Change Summary
vm/src/stdlib/stat.rs Added conditional compilation to define S_IFWHT as 0o160000 on macOS, 0 on other systems.

Poem

In stat.rs a change took flight,
Whiteout files now set just right.
On macOS, a special tune,
0o160000 makes us swoon.
Elsewhere, zero holds the line—
Platform quirks, now by design!

Learning: In RustPython's stat module implementation, platform-specific constants like SF_SUPPORTED and SF_SYNTHETIC should be conditionally declared only for the platforms where they're available (e.g., macOS), following CPython's approach of optional declaration using #ifdef checks rather than providing fallback values for other platforms.

76-81: LGTM! Proper platform-specific conditional compilation.

This change correctly implements platform-specific conditional compilation for S_IFWHT, aligning with macOS's definition (0o160000) while maintaining a fallback value (0) for other platforms. This follows the established pattern in the codebase and aligns with the retrieved learnings about platform-specific constants.
