* cp could read from freed memory and could even make corrupt copies.
This could happen with a very fragmented and sparse input file,
on GNU/Linux file systems supporting fiemap extent scanning.
This bug also affects mv when it resorts to copying, and install.
[bug introduced in coreutils-8.11]
OBS-URL: https://build.opensuse.org/package/show/Base:System/coreutils?expand=0&rev=160
** Bug fixes
* stat no longer reports a negative file size as a huge positive
number. [bug present since 'stat' was introduced in
fileutils-4.1.9]
** New features
* split and truncate now allow any seekable files in situations
where the file size is needed, instead of insisting on regular
files.
* fmt now accepts the --goal=WIDTH (-g) option.
* stat -f recognizes new file system types: bdevfs, inodefs, qnx6
** Changes in behavior
* cp,mv,install,cat,split: now read and write a minimum of 64KiB at
a time. This was previously 32KiB and increasing to 64KiB was
seen to increase throughput by about 10% when reading cached
files on 64 bit GNU/Linux.
* cp --attributes-only no longer truncates any existing destination
file, allowing for more general copying of attributes from one
file to another.

* id and groups, when invoked with no user name argument, would
print the default group ID listed in the password database, and
sometimes that ID would be neither real nor effective. For
example, when run set-GID, or in a session for which the default
group has just been changed, the new group ID would be listed,
even though it is not yet effective.
* 'cp S D' is no longer subject to a race: if an existing D were
removed between the initial stat and subsequent
open-without-O_CREAT, cp would fail with a confusing diagnostic
saying that the destination, D, was not found. Now, in this
unusual case, it retries the open (but with O_CREAT), and hence
usually succeeds. With NFS attribute caching, the condition was
particularly easy to trigger, since there, the removal of D could
precede the initial stat. [This bug was present in "the
beginning".] (bnc#760926).

- Improvements:
* As a GNU extension, 'chmod', 'mkdir', and 'install' now accept
operators '-', '+', '=' followed by octal modes;
* Also, ordinary numeric modes with five or more digits no longer
preserve setuid and setgid bits, so that 'chmod 00755 FOO' now
clears FOO's setuid and setgid bits.
* dd now accepts the count_bytes, skip_bytes iflags and the
seek_bytes oflag, to more easily allow processing portions of a
file.
* dd now accepts the conv=sparse flag to attempt to create sparse
output, by seeking rather than writing to the output file.
* ln now accepts the --relative option, to generate a relative
symbolic link to a target, irrespective of how the target is
specified.
* split now accepts an optional "from" argument to
--numeric-suffixes, which changes the start number from the
default of 0.
* split now accepts the --additional-suffix option, to append an
additional static suffix to output file names.
* basename now supports the -a and -s options, which allow
processing of more than one argument at a time. Also the
complementary -z option was added to delimit output items with
the NUL character.
* dirname now supports more than one argument. Also the complementary
z option was added to delimit output items with the NUL character.
- Bug fixes
* du --one-file-system (-x) would ignore any non-directory
specified on the command line. For example, "touch f; du -x f"
would print nothing. [bug introduced in coreutils-8.15]
* mv now lets you move a symlink onto a same-inode destination
file that has two or more hard links.
* "mv A B" could succeed, yet A would remain.
* realpath no longer mishandles a root directory.
- Improvements
* ls can be much more efficient, especially with large directories
on file systems for which getfilecon-, ACL-check- and XATTR-
check-induced syscalls fail with ENOTSUP or similar.
* 'realpath --relative-base=dir' in isolation now implies
'--relative-to=dir' instead of causing a usage failure.
* split now supports an unlimited number of split files as default
behavior.
For a detaild list se NEWS in the documentation.
- Add up-to-date german translation.
- Add two upstream patches that speed up ls (bnc#752943):
* Cache (l)getfilecon calls to avoid the vast majority of the failing
underlying getxattr syscalls.
* Avoids always-failing queries for whether a file has a nontrivial
ACL and for whether a file has certain "capabilities".

do that.
- Add support for environment variable SU_COMMAND_OPENS_SESSION
that makes su option -c behave like -C (bnc#697897) and document it
in coreutils.info.
- Change name of environment variable to SU_C_SAME_SESSION and
document it properly (bnc#697897).

** New programs
realpath: print resolved file names.
** Bug fixes
du --one-file-system (-x) would ignore any non-directory specified on
the command line. For example, "touch f; du -x f" would print nothing.
[bug introduced in coreutils-8.14]
du -x no longer counts root directories of other file systems.
[bug introduced in coreutils-5.1.0]
ls --color many-entry-directory was uninterruptible for too long
[bug introduced in coreutils-5.2.1]
ls's -k option no longer affects how ls -l outputs file sizes.
It now affects only the per-directory block counts written by -l,
and the sizes written by -s. This is for compatibility with BSD
and with POSIX 2008. Because -k is no longer equivalent to
--block-size=1KiB, a new long option --kibibyte stands for -k.
[bug introduced in coreutils-4.5.4]
ls -l would leak a little memory (security context string) for each
nonempty directory listed on the command line, when using SELinux.
[bug probably introduced in coreutils-6.10 with SELinux support]
split -n 1/2 FILE no longer fails when operating on a growing file, or
(on some systems) when operating on a non-regular file like /dev/zero.
It would report "/dev/zero: No such file or directory" even though
the file obviously exists. Same for -n l/2.
[bug introduced in coreutils-8.8, with the addition of the -n option]
stat -f now recognizes the FhGFS and PipeFS file system types.
tac no longer fails to handle two or more non-seekable inputs
[bug introduced in coreutils-5.3.0]
tail -f no longer tries to use inotify on GPFS or FhGFS file systems
[you might say this was introduced in coreutils-7.5, along with inotify
support, but the new magic numbers weren't in the usual places then.]
** Changes in behavior
df avoids long UUID-including file system names in the default listing.
With recent enough kernel/tools, these long names would be used, pushing
second and subsequent columns far to the right. Now, when a long name
refers to a symlink, and no file systems are specified, df prints the
usually-short referent instead.
tail -f now uses polling (not inotify) when any of its file arguments
resides on a file system of unknown type. In addition, for each such
argument, tail -f prints a warning with the FS type magic number and a
request to report it to the bug-reporting address.

Bug fixes:
- ls --dereference no longer outputs erroneous "argetm" strings for
dangling symlinks when an 'ln=target' entry is in $LS_COLORS.
[bug introduced in fileutils-4.0]
- ls -lL symlink once again properly prints "+" when the referent has
an ACL. [bug introduced in coreutils-8.13]
- sort -g no longer infloops for certain inputs containing NaNs [bug
introduced in coreutils-8.5]
- chown and chgrp with the -v --from= options, now output the correct
owner. I.E. for skipped files, the original ownership is output,
not the new one. [bug introduced in sh-utils-2.0g]
- cp -r could mistakenly change the permissions of an existing
destination directory. [bug introduced in coreutils-6.8]
- cp -u -p would fail to preserve one hard link for each up-to-date
copy of a src-hard-linked name in the destination tree. I.e., if
s/a and s/b are hard-linked and dst/s/a is up to date, "cp -up s
dst" would copy s/b to dst/s/b rather than simply linking dst/s/b
to dst/s/a. [This bug appears to have been present in "the
beginning".]
- fts-using tools (rm, du, chmod, chgrp, chown, chcon) no longer use
memory proportional to the number of entries in each directory they
process. Before, rm -rf 4-million-entry-directory would consume
about 1GiB of memory. Now, it uses less than 30MB, no matter how
many entries there are. [this bug was inherent in the use of fts:
thus, for rm the bug was introduced in coreutils-8.0. The prior
implementation of rm did not use as much memory. du, chmod, chgrp
and chown started using fts in 6.0. chcon was added in
coreutils-6.9.91 with fts support. ]
- pr -T no longer ignores a specified LAST_PAGE to stop at. [bug
introduced in textutils-1.19q]
- printf '%d' '"' no longer accesses out-of-bounds memory in the
diagnostic. [bug introduced in sh-utils-1.16]
- split --number l/... no longer creates extraneous files in certain
cases. [bug introduced in coreutils-8.8]
- timeout now sends signals to commands that create their own process
group. timeout is no longer confused when starting off with a
child process. [bugs introduced in coreutils-7.0]
- unexpand -a now aligns correctly when there are spaces spanning a
tabstop, followed by a tab. In that case a space was dropped,
causing misalignment. We also now ensure that a space never
precedes a tab. [bug introduced in coreutils-5.3.0]
New features:
- date now accepts ISO 8601 date-time strings with "T" as the
separator. It has long parsed dates like "2004-02-29 16:21:42"
with a space between the date and time strings. Now it also parses
"2004-02-29T16:21:42" and fractional-second and time-zone-annotated
variants like "2004-02-29T16:21:42.333-07:00"
- md5sum accepts the new --strict option. With --check, it makes the
tool exit non-zero for any invalid input line, rather than just warning.
This also affects sha1sum, sha224sum, sha384sum and sha512sum.
- split accepts a new --filter=CMD option. With it, split filters
output through CMD. CMD may use the $FILE environment variable,
which is set to the nominal output file name for each invocation of
CMD. For example, to split a file into 3 approximately equal
parts, which are then compressed:
split -n3 --filter='xz > $FILE.xz' big
Note the use of single quotes, not double quotes. That creates
files named xaa.xz, xab.xz and xac.xz.
- timeout accepts a new --foreground option, to support commands not
started directly from a shell prompt, where the command is
interactive or needs to receive signals initiated from the
terminal.
Improvements:
- md5sum --check now supports the -r format from the corresponding
BSD tool. This also affects sha1sum, sha224sum, sha384sum and
sha512sum.
- pwd now works also on systems without openat. On such systems, pwd
would fail when run from a directory whose absolute name contained
more than PATH_MAX / 3 components. The df, stat and readlink
programs are also affected due to their use of the canonicalize_*
functions.
- join --check-order now prints "join: FILE:LINE_NUMBER: bad_line"
for an unsorted input, rather than e.g., "join: file 1 is not in
sorted order".
- shuf outputs small subsets of large permutations much more
efficiently. For example `shuf -i1-$((2**32-1)) -n2` no longer
exhausts memory.
- stat -f now recognizes the GPFS, MQUEUE and PSTOREFS file system
types.
- timeout now supports sub-second timeouts.
Changes in behavior:
- chmod, chown and chgrp now output the original attributes in
messages, when -v or -c specified.
- cp -au (where --preserve=links is implicit) may now replace newer
files in the destination, to mirror hard links from the source.
OBS-URL: https://build.opensuse.org/package/show/Base:System/coreutils?expand=0&rev=128
* Bug fixes
tail's --follow=name option no longer implies --retry on systems
with inotify support. [bug introduced in coreutils-7.5]
* Changes in behavior
cp's extent-based (FIEMAP) copying code is more reliable in the face
of varying and undocumented file system semantics:
- it no longer treats unwritten extents specially
- a FIEMAP-based extent copy always uses the FIEMAP_FLAG_SYNC flag.
Before, it would incur the performance penalty of that sync only
for 2.6.38 and older kernels. We thought all problems would be
resolved for 2.6.39.
- it now attempts a FIEMAP copy only on a file that appears sparse.
Sparse files are relatively unusual, and the copying code incurs
the performance penalty of the now-mandatory sync only for them.
OBS-URL: https://build.opensuse.org/package/show/Base:System/coreutils?expand=0&rev=112
* Bug fixes
cp -a --link would not create a hardlink to a symlink, instead
copying the symlink and then not preserving its timestamp.
[bug introduced in coreutils-8.0]
cp now avoids FIEMAP issues with BTRFS before Linux 2.6.38,
which could result in corrupt copies of sparse files.
[bug introduced in coreutils-8.10]
cut could segfault when invoked with a user-specified output
delimiter and an unbounded range like "-f1234567890-".
[bug introduced in coreutils-5.3.0]
du would infloop when given --files0-from=DIR
[bug introduced in coreutils-7.1]
sort no longer spawns 7 worker threads to sort 16 lines
[bug introduced in coreutils-8.6]
touch built on Solaris 9 would segfault when run on Solaris 10
[bug introduced in coreutils-8.8]
wc would dereference a NULL pointer upon an early out-of-memory error
[bug introduced in coreutils-7.1]
** New features
dd now accepts the 'nocache' flag to the iflag and oflag options,
which will discard any cache associated with the files, or
processed portion thereof.
dd now warns that 'iflag=fullblock' should be used,
in various cases where partial reads can cause issues.
** Changes in behavior
cp now avoids syncing files when possible, when doing a FIEMAP copy.
The sync is only needed on Linux kernels before 2.6.39.
[The sync was introduced in coreutils-8.10]
OBS-URL: https://build.opensuse.org/package/show/Base:System/coreutils?expand=0&rev=109
* Bug fixes
- du would abort with a failed assertion when two conditions are
met: part of the hierarchy being traversed is moved to a higher
level in the directory tree, and there is at least one more
command line directory argument following the one containing
the moved sub-tree. [bug introduced in coreutils-5.1.0]
- join --header now skips the ordering check for the first line
even if the other file is empty. [bug introduced in
coreutils-8.5]
- rm -f no longer fails for EINVAL or EILSEQ on file systems that
reject file names invalid for that file system.
- uniq -f NUM no longer tries to process fields after end of
line. [bug introduced in coreutils-7.0]
* New features
- cp now copies sparse files efficiently on file systems with
FIEMAP support (ext4, btrfs, xfs, ocfs2). Before, it had to
read 2^20 bytes when copying a 1MiB sparse file. Now, it
copies bytes only for the non-sparse sections of a file.
Similarly, to induce a hole in the output file, it had to
detect a long sequence of zero bytes. Now, it knows precisely
where each hole in an input file is, and can reproduce them
efficiently in the output file. mv also benefits when it
resorts to copying, e.g., between file systems.
- join now supports -o 'auto' which will automatically infer the
output format from the first line in each file, to ensure the
same number of fields are output for each line.
* Changes in behavior
- join no longer reports disorder when one of the files is empty.
OBS-URL: https://build.opensuse.org/package/show/Base:System/coreutils?expand=0&rev=85
** Bug fixes
cp -u no longer does unnecessary copying merely because the source
has finer-grained time stamps than the destination.
od now prints floating-point numbers without losing information, and
it no longer omits spaces between floating-point columns in some cases.
sort -u with at least two threads could attempt to read through a
corrupted pointer. [bug introduced in coreutils-8.6]
sort with at least two threads and with blocked output would busy-loop
(spinlock) all threads, often using 100% of available CPU cycles to
do no work. I.e., "sort < big-file | less" could waste a lot of power.
[bug introduced in coreutils-8.6]
sort with at least two threads no longer segfaults due to use of pointers
into the stack of an expired thread. [bug introduced in coreutils-8.6]
sort --compress no longer mishandles subprocesses' exit statuses,
no longer hangs indefinitely due to a bug in waiting for subprocesses,
and no longer generates many more than NMERGE subprocesses.
sort -m -o f f ... f no longer dumps core when file descriptors are limited.
csplit no longer corrupts heap when writing more than 999 files,
nor does it leak memory for every chunk of input processed
[the bugs were present in the initial implementation]
tail -F once again notices changes in a currently unavailable
remote directory [bug introduced in coreutils-7.5]
** Changes in behavior
sort will not create more than 8 threads by default due to diminishing
performance gains. Also the --parallel option is no longer restricted
to the number of available processors.
cp --attributes-only now completely overrides --reflink.
Previously a reflink was needlessly attempted.
OBS-URL: https://build.opensuse.org/package/show/Base:System/coreutils?expand=0&rev=77
o bugfixes
* du no longer multiply counts a file that is a directory or whose
link count is 1.
* du -H and -L now consistently count pointed-to files instead of
symbolic links, and correctly diagnose dangling symlinks.
* du --ignore=D now ignores directory D even when that directory is
found to be part of a directory cycle.
* split now diagnoses read errors rather than silently exiting.
* tac would perform a double-free when given an input line longer
than 16KiB.
* tail -F once again notices changes in a currently unavailable
directory, and works around a Linux kernel bug where inotify runs
out of resources.
* tr now consistently handles case conversion character classes.
o New features
* cp now accepts the --attributes-only option to not copy file data.
* du recognizes -d N as equivalent to --max-depth=N
* sort now accepts the --debug option, to highlight the part of the
line significant in the sort, and warns about questionable options.
* sort now supports -d, -f, -i, -R, and -V in any combination.
* stat now accepts the %m format directive to output the mount point
for a file. It also accepts the %w and %W format directives for
outputting the birth time of a file, if one is available.
o Changes in behavior
* df now consistently prints the device name for a bind mounted file,
rather than its aliased target.
* du now uses less than half as much memory when operating on trees
with many hard-linked files.
OBS-URL: https://build.opensuse.org/package/show/Base:System/coreutils?expand=0&rev=18
Bug fixes
* cp and mv once again support preserving extended attributes.
* cp now preserves "capabilities" when also preserving file ownership.7
* ls --color once again honors the 'NORMAL' dircolors directive.
[bug introduced in coreutils-6.11]
* sort -M now handles abbreviated months that are aligned using
blanks in the locale database. Also locales with 8 bit characters
are handled correctly, including multi byte locales with the caveat
that multi byte characters are matched case sensitively.
* sort again handles obsolescent key formats (+POS -POS) correctly.
Previously if -POS was specified, 1 field too many was used in the
sort. [bug introduced in coreutils-7.2]
New features
* join now accepts the --header option, to treat the first line of
each file as a header line to be joined and printed
unconditionally.
* timeout now accepts the --kill-after option which sends a kill
signal to the monitored command if it's still running the specified
duration after the initial signal was sent.
* who: the "+/-" --mesg (-T) indicator of whether a user/tty is
accepting messages could be incorrectly listed as "+", when in
fact, the user was not accepting messages (mesg no). Before, who
would examine only the permission bits, and not consider the group
of the TTY device file. Thus, if a login tty's group would change
somehow e.g., to "root", that would make it unwritable (via
write(1)) by normal users, in spite of whatever the permission bits
might imply. Now, when configured using the
--with-tty-group[=NAME] option, who also compares the group of the
TTY device with NAME (or "tty" if no group name is specified).
Changes in behavior
* ls --color no longer emits the final 3-byte color-resetting escape
sequence when it would be a no-op.
* join -t '' no longer emits an error and instead operates on each
line as a whole (even if they contain NUL characters).
