* Noteworthy changes in release 7.3 (2009-05-01) [stable]


** Bug fixes

cp now diagnoses failure to preserve selinux/xattr attributes when
--preserve=context,xattr is specified in combination with -a.
Also, cp no longer suppresses attribute-preservation diagnostics
when preserving SELinux context was explicitly requested.

ls now aligns output correctly in the presence of abbreviated month
names from the locale database that have differing widths.

ls -v and sort -V now order names like "#.b#" properly

mv: do not print diagnostics when failing to preserve xattr's on file
systems without xattr support.

sort -m no longer segfaults when its output file is also an input file.
E.g., with this, touch 1; sort -m -o 1 1, sort would segfault.
[introduced in coreutils-7.2]

** Changes in behavior

shred, sort, shuf: now use an internal pseudorandom generator by default.
This is mainly noticable in shred where the 3 random passes it does by
default should proceed at the speed of the disk. Previously /dev/urandom
was used if available, which is relatively slow on GNU/Linux systems.

** Improved robustness

cp would exit successfully after copying less than the full contents
of a file larger than ~4000 bytes from a linux-/proc file system to a
destination file system with a fundamental block size of 4KiB or greater.
Reading into a 4KiB-or-larger buffer, cp's "read" syscall would return
a value smaller than 4096, and cp would interpret that as EOF (POSIX
allows this). This optimization, now removed, saved 50% of cp's read
syscalls when copying small files. Affected linux kernels: at least
2.6.9 through 2.6.29.
[the optimization was introduced in coreutils-6.0]

** Portability

df now pre-mounts automountable directories even with automounters for
which stat-like syscalls no longer provoke mounting. Now, df uses open.

`id -G $USER` now works correctly even on Darwin and NetBSD. Previously it
would either truncate the group list to 10, or go into an infinite loop,
due to their non-standard getgrouplist implementations.
[truncation introduced in coreutils-6.11]
[infinite loop introduced in coreutils-7.1]
