🟢 Approval recommended
The changes are small, self-contained, and preserve the existing comparison semantics while reducing dependencies and unnecessary computation.
Pull request overview
This PR makes small, localized optimizations to the FileSystem component’s common string helpers, primarily reducing dependency on ctype.h and avoiding unnecessary work during comparisons.
Changes:
- Reworked
fs_strncasecmp()to perform ASCII-only case folding via bit operations instead oftolower(), removing thectype.hinclude. - Optimized
fs_strmatch()to skip trailing comparison and length calculations when the leading comparison already fails. - Minor documentation updates (clarify ASCII scope, fix “beggining” typo) and copyright year bump.
