* src/pr.c (main): Avoid this warning from GCC 7:
src/pr.c:1119:6: error: assuming signed overflow does not occur when \
simplifying conditional to constant [-Werror=strict-overflow]
if (n_files == 0)
|
|
* .gitignore: Add /lib/limits.h.
* tests/misc/printf-quote.sh: Reflect that a single quote is now
rendered as "'", rather than as ''\'''.
|
|
* src/rm.c (main): Ensure the full --no-preserve-root
option is specified, rather than allowing --n etc.
* tests/rm/r-root.sh: Add a test case.
* NEWS: Mention the change in behavior.
Improved by Jim Meyering.

which was not the case when inotify was not available.
* src/tail.c (any_live_files): Simplify, since the IGNORE
flag is now only set when a file should be ignored indefinitely.
(recheck): Only output the "giving up on name" message
when that's actually the case. Only set the IGNORE flag
when ignoring a file indefinitely.
(tail_file): Likewise.
* tests/tail-2/retry.sh: Add a test case. Also run
all existing test cases with and without inotify.
NEWS: Mention the fix.
THANKS.in: Add the reporter.
Fixes http://bugs.gnu.org/24495 which was detected
using Symbolic Execution techniques developed in
the course of the SYMBIOSYS research project at
COMSYS, RWTH Aachen University.

* src/who.c (idle_string): This function would fail to compile
with -Werror and today's built-from-git gcc due to this warning:
src/who.c: In function 'print_user':
src/who.c:201:36: error: may write format character ':' at offset 4 \
past the end of the destination [-Werror=format-length=]
sprintf (idle_hhmm, "%02d:%02d",
^~~~~
The fix is to use an assertion to inform gcc of the existing
invariant that guarantees the number of hours is less than 24.

The old code mishandled --time-spec='+%%b', as it misinterpreted
the '%b' as being the month abbreviation. Also, it mishandled
the extremely unlikely case of a month abbreviation containing '%'.
The performance part of this patch sped up 'ls' by about 1% on my
little benchmark of 'ls -lR' on the source directory in the
en_US.UTF-8 locale (Fedora 24 x86-64).
* NEWS: Document the bug fix.
* src/ls.c (first_percent_b, abformat_init): New static functions.
(ABFORMAT_SIZE): New constant.
(use_abformat): New static var.
(abmon, required_mon_width): Remove these static vars.
(abmon_init): Now accepts a pointer to abmon, and returns a boolean.
All callers changed. Reject month abbrs containing '%', as these
would mess up strftime. Simplify mbsalign result checking,
since (size_t) -1 exceeds ABFORMAT_SIZE.
(abformat_init, align_nstrftime): Precompute all 24 formats at
startup, rather than computing a format for each time stamp.
(decode_switches): Call abformat_init instead of abmon_init.
(align_nstrftime): Accept recentness bool instead of format.
All callers changed.
* tests/misc/time-style.sh: Test for format with '%%b'.

Given that `ttyname` is already conditionally declared in src/system.h,
other declarations are redundant and problematic for example in ChromeOS
which has a new FORTIFY implementation that, as an artifact of how it's
implemented, causes the compiler to complain if certain standard library
functions are redeclared without special compiler-specific attributes.
* src/pinky.c: Remove declaration (which was unused anyway).
* src/who.c: Remove declaration.
* src/system.h (getlogin, getuid, geteuid, getgrgid, getpwuid, ttyname):
Add the parameter type to the declarations to avoid warnings when these
backup declarations are used.

Compiling in gnulib-tests/ would fail on some platforms
due to a missing lib/assert.h. Reported by Assaf Gordon in

This doesn't affect the generated code on my system; it's merely
a cleaner way to use the recently-introduced Linux-specific API.
* m4/jm-macros.m4 (gl_CHECK_ALL_HEADERS): Check for linux/fs.h.
* src/copy.c: Include <linux.fs.h> if available.
(FICLONE) [__linux__]: Define if not already defined.
(clone_file): Use FICLONE instead of the older BTRFS_IOC_CLONE,
as this ioctl is no longer btrfs-specific.

Postpone installation of signal handlers until they're needed.
That is right before the first escape sequence is printed.
* src/ls.c (signal_setup): A new function refactored from main()
to set and restore signal handlers.
(main): Move signal handler setup to put_indicator()
so that the default signal handling is untouched as long as possible.
Adjusted condition for restoring signal handlers to reflect the change.
(put_indicator): Install signal handlers if called for the very first
time. It uses the same code that was in main() prior to this commit.
* NEWS: Mention the improvement.

Zstandard/zstd compression tools. See http://zStd.net and
https://code.facebook.com/posts/1658392934479273/
|
|
* src/tr.c (unquote): Use indices of type "unsigned int", rather
than a mix or "size_t" and "int", presuming that no command-line-
specified string will have length longer than UINT_MAX.
|
|
|
|
* src/ptx.c (fix_output_parameters): Switch to an unsigned type that
matches the OCCURS.file_index type. This avoids the following error
from gcc-7.0.0 20160829 (experimental):
src/ptx.c:1220:14: error: assuming signed overflow does not occur \
when simplifying conditional to constant [-Werror=strict-overflow]

* src/expand-common.h, src/expand-common.c: ... to here.
* src/expand.c, src/unexpand.c: (parse_tab_stops, validate_tab_stops,
next_file): Move identical functions to new module.
(add_tab_stop): Move to new module, including additional code from
'unexpand' (keeping max_column_width) which will have no effect in when
used in 'expand'. Refactor common next-column calculation code
into a new function 'get_next_tab_column'.
* src/local.mk: (src_expand_SOURCES, src_unexpand_SOURCES): Add
'expand-common.c'; (noinst_HEADERS): Add 'expand-common.h'.
* po/POTFILES.in: Add 'expand-common.c'.
* tests/misc/expand.pl: Add more tests.
* tests/misc/unexpand.pl: Likewise.
* TODO: Move conclusions to above test after investigation.

Use hash table for seaching in filter_mount_list() and get_dev()
This improves performance for 20K mount entries from:
real 0m1.731s
user 0m0.532s
sys 0m1.188s
to:
real 0m1.066s
user 0m0.028s
sys 0m1.032s
* src/df.c (devlist_table): Define hash table.
(devlist_hash): Add hash function.
(devlist_compare): Add hash comparison function.
(devlist_for_dev): Add lookup function.
(devlist_free): Add cleanup function.
(filter_mount_list): Use the above hash table.
While at it, rename the variable 'devlist' to 'seen_dev' for
better readability.

The following is a reproducer for the wrong dependency:
$ ./configure --enable-install-program=arch
$ make
$ rm -f src/arch man/arch.1
$ make man/arch.1
GEN man/arch.1
help2man: can't get `--help' info from man/arch.td/arch
Try `--no-discard-stderr' if option outputs to stderr
Makefile:14378: recipe for target 'man/arch.1' failed
make: *** [man/arch.1] Error 127
* man/local.mk (man/arch.1): Change to depend on src/arch rather than
src/uname: while the arch binary depends on uname.c and uname-arch.c,
its man page depends on the arch binary.

* tests/rm/rm-readdir-fail.sh: Since we use the returned dirent
from the readdir wrapper it must be the correct type and not
just cast. Therefore setup so that we only have to define a
wrapper for readdir(), which works appropriately on 32 and 64 bit.
Issue reported by Bernhard Voelker, where rm was seen to invoke
rmdir() on invalid file names.

* tests/rm/rm-readdir-fail.sh: A new test to simulate readdir()
failing immediately or after returning a few entries, and verifying
that rm does the appropriate thing.
This was initially reported at:
http://bugzilla.opensuse.org/show_bug.cgi?id=984910
where it was mentioned that readdir() may fail
when an NFS server has a poor readdir cookie implementation.

* src/yes.c: Include full-write.h.
(main): Use full_write, not write, to simplify handling of partial
writes. Don't bother using stdio to output data; just use
full_write with a buffer as large as needed. Reuse operand
strings if possible, and if the buffer would otherwise be large.
|

* doc/coreutils.texi (sort invocation): Mention in the summary
dicussion that --key is used to specify fields. Give a summary
in the --key description, of the most common use case of specifying
a field, and that by default those fields include the blank separators
at the start of each field in the comparisons.

Easier troubleshooting of individual 'sort --debug' messages.
Discussed in http://bugs.gnu.org/23665 .
* tests/misc/sort-debug-warn.sh: add progress number before each sort
invocation.
