However, code was only checking `#[cfg(feature = "selinux")]`, causing compilation failures on macOS/BSDs where uucore::selinux doesn't exist. Fixed by updating all SELinux feature checks from: `#[cfg(feature = "selinux")]` to: `#[cfg(all(feature = "selinux", target_os = "linux"))]` Modified files: - src/uu/cp/src/cp.rs (2 locations) - src/uu/id/src/id.rs (4 locations) - src/uu/install/src/install.rs (17 locations) - src/uu/mkdir/src/mkdir.rs (1 location) - src/uu/mkfifo/src/mkfifo.rs (1 location) - src/uu/mknod/src/mknod.rs (1 location) - src/uu/stat/src/stat.rs (2 locations) **Type Conversion Fix:** On macOS, `libc::mode_t` is `u16` while `metadata.permissions().mode()` returns `u32`, causing a type mismatch in rm's safe_traversal code. Fixed in src/uu/rm/src/platform/unix.rs:320 by adding explicit cast: `initial_mode as libc::mode_t` **Test Fix:** Updated test_chmod_recursive to expect consistent error messages across all Unix platforms. With safe_traversal now enabled universally on Unix, the detailed error format "cannot access 'z': Permission denied" is used on all platforms, not just Linux. Modified: tests/by-util/test_chmod.rs **Verification:** - ✅ All unit tests pass (chmod, du, rm, cp, id, stat, mkdir, mkfifo, mknod, install, uucore) - ✅ All functional tests pass - ✅ cargo build --features feat_os_macos - ✅ cargo build --features feat_os_unix - ✅ cargo clippy (macOS & Unix features) - ✅ cargo fmt --all -- --check - ✅ chmod integration tests (40/40 passed) --- src/uu/cp/src/cp.rs | 4 ++-- src/uu/id/src/id.rs | 8 ++++---- src/uu/install/src/install.rs | 34 +++++++++++++++++----------------- src/uu/mkdir/src/mkdir.rs | 2 +- src/uu/mkfifo/src/mkfifo.rs | 2 +- src/uu/mknod/src/mknod.rs | 2 +- src/uu/rm/src/platform/unix.rs | 2 +- src/uu/stat/src/stat.rs | 4 ++-- tests/by-util/test_chmod.rs | 5 ++--- 9 files changed, 31 insertions(+), 32 deletions(-) diff --git a/src/uu/cp/src/cp.rs b/src/uu/cp/src/cp.rs index 036e9f9ee55..185afa093d6 100644 --- a/src/uu/cp/src/cp.rs +++ b/src/uu/cp/src/cp.rs @@ -1732,7 +1732,7 @@ pub(crate) fn copy_attributes( Ok(()) })?;

These casts are unnecessary on Linux where types are already u64/u32, but required on macOS/BSD where: - st_dev is i32 (needs cast to u64) - st_mode is u16 (needs cast to u32) - st_rdev is i32 (needs cast to u64) 2. **Android type mismatch** - Cast st_mode to libc::mode_t in file_type() method. On Android, st_mode is u32 but libc::mode_t is u16, causing compilation failure when passing to FileType::from_mode(). These fixes match the existing pattern already used for st_ino and st_nlink.

Changes: - Add direct libc import for Redox (nix::libc not available) - Gate Metadata struct, impl, and MetadataExt trait (use FileStat) - Gate metadata_at() and metadata() methods (return Metadata) - Revert unrelated locale test changes from commit 57043553c The Redox platform lacks support for nix::sys::stat::FileStat, causing build failures. These items now follow the existing pattern of returning "safe_traversal is not supported on Redox" errors via gated stub methods. --- src/uu/date/src/locale.rs | 77 +++++++------------ src/uucore/src/lib/features/safe_traversal.rs | 7 ++ 2 files changed, 34 insertions(+), 50 deletions(-) diff --git a/src/uu/date/src/locale.rs b/src/uu/date/src/locale.rs index 0e3ce740d22..0dea975f97f 100644 --- a/src/uu/date/src/locale.rs +++ b/src/uu/date/src/locale.rs @@ -121,62 +121,39 @@ mod tests { #[test] fn test_default_format_contains_valid_codes() { let format = get_locale_default_format();
