* src/tail.c (tail_forever_inotify): Only monitor write()s and
truncate()s to files in --follow=descriptor mode, thus avoiding
the bug where we removed the watch on renamed files.
Also adjust the inotify event processing code that is
now significant only in --follow=name mode.
* tests/tail-2/F-vs-rename.sh: Improve this existing test by running
in both polling and inotify modes.
* tests/tail-2/f-vs-rename.sh: A new test based on the existing one.

Using a test file generated with:
yes | head -n100M > 2x100M.txt
before> time wc -l 2x100M.txt
real 0.842s
user 0.810s
sys 0.033s
after> time wc -l 2x100M.txt
real 0.142s
user 0.111s
sys 0.031s
* src/wc.c (wc): Split the loop that deals with -l into 3.
The first is used at the start of the input to determine if
the average line length is < 15, and if so the second loop is
used to look for '\n' internally to wc. For longer lines,
memchr is used as before to take advantage of system specific
optimizations which any outweigh function call overhead.
Note the first 2 loops could be combined, though in testing,
GCC 4.9.2 at least, wasn't sophisticated enough to separate
the loops based on the "check_len" invariant.
Note also __builtin_memchr() isn't significant here as
GCC currently only applies constant folding with that.
* NEWS: Mention the improvement.

Adjust commit v8.23-140-gfdd6ebf to add the --output-error option
instead of --write-error, and treat open() errors like write() errors.
* doc/coreutils.texi (tee invocation): s/write-error/output-error/.
* src/tee.c (main): Exit on open() error if appropriate.
* tests/misc/tee.sh: Add a case to test open() errors.
* NEWS: Adjust for the more general output error behavior.
Suggested by Bernhard Voelker.

Note that IBRIX used to have a different magic number 0x013111A7
instead of the current 0x013111A8. However, the former is no longer
used and the version of IBRIX it was used in is really ancient, so
it's extremely unlikely anyone is still using it. Therefore, just
add the newer magic number.
Mark IBRIX as a 'remote' file system type as inotify support had
never been officially tested with it.
* src/stat.c (human_fstype): Add file system ID definition.
* NEWS: Mention the improvement.

tee is very often used with pipes and this gives better control
when writing to them. There are 3 classes of file descriptors
that tee can write to: files(1), pipes(2), and early close pipes(3).
Handling write errors to 1 & 2 is supported at present with the caveat
that failure writing to any pipe will terminate tee immediately.
Handling write errors to type 3 is not currently supported.
To improve the supported combinations we add these options:
--write-error=warn
Warn if error writing any output including pipes.
Allows continued writing to still open files/pipes.
Exit status is failure if any output had error.
--write-error=warn-nopipe, -p
Warn if error writing any output except pipes.
Allows continued writing to still open files/pipes.
Exit status is failure if any non pipe output had error.
--write-error=exit
Exit if error writing any output including pipes.
--write-error=exit-nopipe
Exit if error writing any output except pipes.
Use the "nopipe" variants when files are of types 1 and 3, otherwise
use the standard variants with types 1 and 2. A caveat with the above
scheme is that a combination of pipe types (2 & 3) is not supported
robustly. I.e. if you use the "nopipe" variants when using both type
2 and 3 pipes, then any "real" errors on type 2 pipes will not be
diagnosed.
Note also a general issue with type 3 pipes that are not on tee's
stdout, is that shell constructs don't allow to distinguish early
close from real failures. For example `tee >(head -n1) | grep -m1 ..`
can't distinguish between an error or an early close in "head" pipe,
while the fail on the grep part of the pipe is distinguished
independently from the resulting pipe errors. This is a general
issue with the >() construct, rather than with tee itself.
* NEWS: Mention the new feature.
* doc/coreutils.texi (tee invocation): Describe the new option.
* src/tee.c (usage): Likewise.

Since v5.2.1-1247-g8dafbe5, tee(1) treated '-' as stdout while POSIX
explicitly requires to treat this as a file name. Revert this change,
as the interleaved output - due to sending another copy of input to
stdout - is not considered to be useful. Discussed in

Each user has a maximum number of inotify watches,
so handle the cases where we exhaust these resources.
* src/tail.c (tail_forever_inotify): Ensure we inotify_rm_watch()

Return all used inotify resources when reverting to polling.
Revert to polling upon first indication of inotify resource exhaustion.
Revert to polling on any inotify resource exhaustion.

To align with all other places (and correct grammar), change all
upper-case "I.E." to "I.e.". Furthermore, ensure that "i.e." is
followed by a comma. Finally, ensure to use a double-space before
"I.e.," at the beginning of a sentence.

This patch fixes the handling of sub-bind-mount cycles which are
incorrectly detected as the file system errors. If you bind mount the
directory 'a' to its subdirectory 'a/b/c' and then run 'du a/b' you
will get the circular dependency warning even though nothing is wrong
with the file system. This happens because the first directory that is
traversed twice in this case is not a bind mount but a child of bind
mount. The solution is to traverse all the directories in the cycle
that fts detected and check whether they are not a (bind) mount.
* src/du.c (mount_point_in_fts_cycle): New function that checks whether
any of the directories in the cycle that fts detected is a mount point.
* src/du.c (process_file): Update the function to use the new function
that looks up all the directories in the fts cycle instead of only the
last one.
* tests/du/bind-mount-dir-cycle-v2.sh: New test case that exhibits the
described behavior.
* tests/local.mk: Reference the new root test.
* NEWS: Mention the bug fix.

"zu" was output on solaris 8 for example rather than the number,
since coreutils-8.22.
* cfg.mk: Disallow %z, since we don't currently use the gnulib
fprintf module, so any usage with it is non portable. Also
our usage with error() currently works only through an ancillary
dependency on the vfprintf gnulib module.

keep the suppression to give a more accurate value for the
total storage available.
(usage): Expand on the new implications of --total and move
it in the options list according to alphabetic order.

We may run into a race condition if we treat hard links to the same file
as distinct files. If we do 'mv a b' and 'mv b a' in parallel, both a
and b can disappear from the file system. The reason is that in this
case the unlink on src is called and the system calls can end up being
run in the order where unlink(a) and unlink(b) are the last two system
calls. Therefore exit with an error code so that we avoid the potential
data loss.
* src/copy.c (same_file_ok): Don't set unlink_src that was used by mv,
and return false for two hardlinks to a file in move_mode.
*src/copy.c (copy_internal): No longer honor the unlink_src option,
used only by mv.
NEWS: Mention the change in behavior.

* src/chroot.c (is_root): Adjust to compare canonicalized paths

we have a tree that is constructed by first bind mounting "/"
(thus having the same inode).
(main): Unconditionally call chroot() because it's safer
and of minimal performance benefit to avoid in this case.
This will cause inconsistency with some platforms

avoid any permanent allocation due to speculative
preallocation employed by file systems such as XFS.
* m4/jm-macros.m4: Check for <linux/falloc.h> and fallocate().
* src/copy.c (punch_hole): A new function to try and punch
a hole at the specified offset if supported.
(create_hole): Call punch_hole() after requesting a hole.
(extent_copy): Likewise.
* NEWS: Mention the improvement.

Previously cp would not detect runs of NULs that were
smaller than the buffer size used for I/O (currently 128KiB).
* src/copy.c (copy_reg): Use an independent hole_size, set to
st_blksize, to increase the chances of detecting a representable hole,
in a run of NULs read from the input.
(create_hole): A new function refactored from sparse_copy() and
extent_copy() so we have a single place to handle holes.
(sparse_copy): Adjust to loop over the larger input buffer
in chunks of the passed hole size. Also adjust to only call
lseek once per hole, rather than at least once per input buffer.
* tests/cp/sparse.sh: Add test cases for various sparse chunk sizes.

On some filesystems (BTRFS), moving a file within the filesystem may
cross subvolume boundaries and we can use a lightweight reflink copy,

Since commit v8.22-94-g99960ee, chroot(1) skips the chroot(2) syscall
for "/" arguments (and synonyms). The problem is that it also skips
the following chdir("/") call in that case. The latter breaks existing
scripts which expect "/" to be the working directory inside the chroot.
While the first part of the change - i.e., skipping chroot("/") - is
okay for consistency with systems where it might succeed for a non-root
user, the second part might be malicious, e.g.
cd /home/user && chroot '/' bin/foo
In the "best" case, chroot(1) could not execute 'bin/foo' with ENOENT,
but in the worst case, chroot(1) would execute '/home/user/bin/foo' in
the case that exists - instead of '/bin/foo'.
Revert that second part of the patch, i.e., perform the chdir("/)
in the common case again - unless the new --skip-chdir option is
specified. Restrict this new option to the case of "/" arguments.
* src/chroot.c (SKIP_CHDIR): Add enum.
(long_opts): Add entry for the new --skip-chdir option.
(usage): Add --skip-chdir option, and while at it, move the other
to options into alphabetical order.
(main): Accept the above new option, allowing it only in the case
when NEWROOT is the old "/".
Move down the chdir() call after the if-clause to ensure it is
run in any case - unless --skip-chdir is specified.
Add a 'newroot' variable for the new root directory as it is used
in a couple of places now.
* tests/misc/chroot-fail.sh: Invert the last tests which check the
working directory of the execvp()ed program when a "/"-like
argument was passed: now expect it to be "/" - unless --skip-chdir
is given.
* doc/coreutils.texi (chroot invocation): Document the new option.
Document that chroot(1) usually calls chdir("/") unless the new
--skip-chdir option is specified. Sort options.
* NEWS (Changes in behavior): Mention the fix.

This didn't seem to cause any invalid operation on GNU/Linux at least,
but depending on the implementation, mutex deadlocks could occur.
For example this might be the cause of lockups seen on Solaris:
http://lists.gnu.org/archive/html/coreutils/2013-03/msg00048.html
This was identified with valgrind 3.9.0 with this setup:
seq 200000 > file.sort
valgrind --tool=drd src/sort file.sort -o file.sort
With that, valgrind would _intermittently_ report the following:
Destroying locked mutex: mutex 0x5419548, recursion count 1, owner 2.
at 0x4C2E3F0: pthread_mutex_destroy(in vgpreload_drd-amd64-linux.so)

* src/sort.c (sortlines): Move pthread_mutex_destroy() out to
merge_tree_destroy(), so that we don't overlap mutex destruction
with threads still operating on the nodes.
(sort): Call the destructors only with "lint" defined, as the
memory used will be deallocated implicitly at process end.
* NEWS: Mention the bug fix.

Add the --enable-single-binary option to the configure file.
When enabled, this option builds a single binary file containing
the selected tools. Which tool gets executed depends on the value
of argv[0] which can be set implicitly through symlinks to the
single program.
This setup reduces significantly the size of a complete coreutils
install, since code from lib/libcoreutils.a is not duplicated in
every one of the more than 100 binaries. Runtime overhead is
increased due to more dynamic libraries being loaded, and extra
initialization being performed for all utils. Also initially
a larger binary is loaded from storage, though this is usually
alleviated due to caching and lazy mmaping of unused blocks,
and in fact the single binary should have better caching
characteristics.
Comparing the size of the individual versus single binary on x86_64:
$ cd src
$ size coreutils
$ size -t $(../build-aux/gen-lists-of-programs.sh --list-progs |
grep -Ev '(coreutils|libstdbuf)') | tail -n1
text data bss dec hex filename
1097416 5388 88432 1191236 122d44 src/coreutils
4901010 124964 163768 5189742 4f306e (TOTALS)
Storage requirements are reduced similarly:
$ cd src
$ du -h coreutils
$ du -ch $(../build-aux/gen-lists-of-programs.sh --list-progs |
grep -Ev '(coreutils|libstdbuf)') | tail -n1
1.2M coreutils
5.3M total
When installing, the makefile will create either symlinks or
shebangs based on the --enable-single-binary setting, for
each configured tool. In this way, all the tools are still
callable individually, but they are all implemented by the same
"coreutils" binary installed on the same directory.

A system provided mount entry may be unavailable due to TOCTOU race,
or if another device has been over-mounted at that position, or due to
access permissions. In all these cases output "-" placeholder values
rather than either producing an error, or in the over-mount case
outputting values for the wrong device.
* src/df.c (device_list): A new global list now updated by
filter_mount_list().
(filter_mount_list): Adjust to take a parameter as to whether
update the global mount list, or only the mount <-> device ID mapping.
(get_dev): Use the device ID mapping to ensure we're not outputting
stats for the wrong device. Also output placeholder values when we
can't access a system specified mount point.
(get_all_entries): Set the DEVICE_ONLY param for filter_mount_list().
(devname_for_dev): A new function to search the mount <-> dev mapping.

commits v8.20-98-g51ce0bf and v8.20-99-gd302aed changed cut(1)
to process each line independently and thus promptly output
each line without buffering. As part of those changes we removed
the special handling of --delimiter=$'\n' --fields=... which
could be used to select arbitrary (ranges of) lines, so as to
simplify and optimize the implementation while also matching the
behavior of different cut(1) implementations.
However that GNU behavior was in place for a long time, and
could be useful in certain cases like making a separated list like
`seq 10 | cut -f1- -d$'\n' --output-delimiter=,` although other tools
like head(1) and paste(1) are more suited to this operation.
This patch reinstates that functionality but restricts the
"line behind" buffering behavior to only the -d$'\n' case.
We also fix the following related edge case to be more consistent:
before> printf "\n" | cut -s -d$'\n' -f1- | wc -l
2
before> printf "\n" | cut -d$'\n' -f1- | wc -l
1
after > printf "\n" | cut -s -d$'\n' -f1- | wc -l
1
after > printf "\n" | cut -d$'\n' -f1- | wc -l
