Lataa coreutils 0.10.0

Rust Coreutils 0.10.0 Release:
We are happy to announce the release of Rust Coreutils 0.10.0 - a release focused on GNU compatibility and robustness. The GNU test suite results improved sharply this cycle (645 passing, 29 failing, down from 56), we landed a second wave of security hardening (TOCTOU races, safe recursive descent, SELinux labeling at creation, backup guards), and we ran a broad anti-panic campaign across the utilities. On top of that: new features (mv --exchange, install --reflink, an OpenSSL backend for the checksum utilities), more zero-copy/read-ahead performance work, and wasm32-wasip2 support.

> Note: 0.9.0 bumped the GNU reference to 9.11, which added 25 new tests and temporarily pushed the failure count up. This cycle absorbed most of that debt: failures dropped from 56 to 29 and passes reached an all-time high of 645.
> As we contributed many tests to the GNU implementation, we are also the source of some of these regressions!

Highlights:
- GNU Compatibility
- 645 passing GNU tests (+20) and 27 fewer failures, the largest single-cycle drop we have had
- Dozens of behavior alignments: pr (-w/-W/-l/-e/-o, merge mode, page ranges), nproc (cgroups v2 quota, affinity mask, offline cores, OMP_* handling), date (out-of-range years, -d -, O modifier, timezone strings), numfmt, ls, du, install, od, truncate, fold, head/tail, sum, stat
- Many error messages now carry the file name and the real OS error instead of a vague or stripped message
- Security Hardening
- Continued the TOCTOU work started in 0.9.0: touch no longer uses O_TRUNC on create, mkfifo drops the path-based chmod, head checks the open fd instead of the path, split hardens the output-open path, chcon anchors recursive relabeling to the traversal dirfd
- Safe recursive descent fixes for chmod/chown (symlink cycles, --preserve-root re-checked during the descent), and cp no longer descends into a destination subdirectory that is a symlink
- SELinux labels are now applied at creation in mkdir, mkfifo and mknod instead of being applied afterwards
- mv fails closed when recreating a cross-device directory destination, compares file identity in the --backup=simple guard, and strips setuid/setgid when a cross-device copy cannot preserve ownership
- chroot chroots exactly the path --skip-chdir validated; stdbuf refuses a libstdbuf path that cannot be represented in LD_PRELOAD; install finalizes ownership before mode
- Added SECURITY.md documenting our threat model, scope and reporting process
- Robustness: Anti-Panic Campaign
- Removed panics and aborts across a long list of utilities: shuf, printf, numfmt, fmt, pr, chroot, dircolors, install, ln, touch, stat, split, expand, more, kill, cp, du, rm, runcon, sort, chown/chgrp, dirname, expr, cksum, dd, truncate, hashsum
- Recurring classes fixed: write failures on /dev/full, char-boundary panics on multibyte input, integer overflow on extreme widths/precisions/sizes, and unbounded allocations for huge arguments
- expr now uses an iterative parser, so deeply nested expressions no longer overflow the stack
- New Features
- mv --exchange to atomically swap two paths
- install --reflink support, and install -C now works with --preserve-timestamps
- OpenSSL backend for the faster checksum utilities
- cut -O as a short option for --output-delimiter
- rm --one-file-system
- timeout now works on Windows, and tail -f/-F finally follows files on Windows
- Performance
- Read-ahead hints across the cksum family, sum, split, expand/unexpand and the base* utilities
- tee zero-copy fast path; cat throughput improvements; faster non-reflink cp; cross-device mv via the fast copy path
- expr: index went from O(N*M) to O(N+M); uniq and du improvements; tsort now buffers its output
- New benchmarks for expr, tr, cut, uniq and locale-aware sort merges
- Internationalization
- cut supports multibyte characters in non-UTF-8 locales
- ls uses Unicode quotes for the locale/clocale styles in UTF-8 locales and escapes non-ASCII control characters
- Fixed C.UTF-8 being detected as ASCII, and incomplete Fluent fallback bundles
- cksum quotes file names in a locale-aware way
- Cross-platform Reach
- New wasm32-wasip2 target support
- Windows: timeout implementation, sparse copy support in cp, tail -f, cksum CRLF fix
- ls --numeric-uid-gid on non-unix platforms, uptime uses CLOCK_BOOTTIME on more platforms
- Code Quality
- clippy::collapsible_if and clippy::match_same_arms are now clean and enabled workspace-wide
- Continued nix → rustix migration (dd, kill, sync, uptime) and further removal of unsafe and to_string_lossy
- Contributions: This release was made possible by 50 new contributors joining our community
