        * NEWS: Record release date.

2017-12-23  Pádraig Brady  <P@draigBrady.com>

        tests: avoid false failure on AIX 7.2
        * tests/tail-2/pipe-f.sh: Close stdout in a subshell
        to ensure the current shell isn't impacted.  Subsequent
        piped commands like `echo foo | blah` were seen to fail
        due to the previous closing of stdout.
        Reported by Assaf Gordon.

        doc: describe recent build checks for 32 bit time_t
        * README: Document the new handling of 32 bit time_t,
        with examples of how to build in 64 bit mode on AIX.
        Also mention that GNU make is desired on AIX
        due to its mishandling of the "[" target.
        Suggested by Assaf Gordon.

        tests: fix recent portability issues on solaris 10
        * tests/misc/ptx.pl: Escape the '^' character which is
        otherwise considered as a line continuation character.
        * tests/misc/shred-remove.sh: sed doesn't support \n.

        maint: remove reference to excluded changelog item
        * build-aux/git-log-fix: Remove old entry.

2017-12-20  Pádraig Brady  <P@draigBrady.com>

        maint: add doc/coverage to .gitignore
        * .gitignore: Ignore the generated coverage report.

        doc: remove older ChangeLog items
        * Makefile.am: Update the oldest documented version
        to 8.20 which is now about 5 years old.

2017-12-18  Bernhard Voelker  <mail@bernhard-voelker.de>

        doc: mention which privileges are needed to chmod
        POSIX specification for chmod(1):
        https://pubs.opengroup.org/onlinepubs/9699919799/utilities/chmod.html

        * doc/coreutils.texi (chmod invocation): Add a sentence about who can
        change the file mode bits of a file - (almost) a copy from what POSIX
        requires.

        Fixes https://bugs.gnu.org/29207.

2017-12-16  Pádraig Brady  <P@draigBrady.com>

        tests: fix recent regressions with dash
        * tests/misc/timeout.sh: dash outputs the "Killed"
        message to stderr rather than the terminal.
        * tests/misc/usage_vs_getopt.sh: dash doesn't yet
        support the POSIX proposed $'...' shell quoting syntax.

        build: avoid a signed overflow warning in ptx
        * src/ptx.c (fix_output_parameters): GCC 6.3.1 with
        ./configure --enable-single-binary would give:
          error: assuming signed overflow does not occur
          when simplifying conditional to constant [-Werror=strict-overflow]
            if (file_index > 0)
        So change the type of file_index to signed (size_t).

2017-12-11  Bernhard Voelker  <mail@bernhard-voelker.de>

        maint: adjust for the renamed nstrfime gnulib module
        * bootstrap.conf: s/strftime/nstrfrime/.

2017-12-11  Pádraig Brady  <P@draigBrady.com>

        build: update gnulib submodule to latest
        * gnulib: Update with various build/test fixes.

        tests: fix false failure in new dd/nocache_eof test
        * test/dd/nocache_eof.sh: Also handle fadvise64_64 which is
        used on 32 bit x86.  Note strace internally maps fadvise64_64
        to {arm,xtensa}_fadvise64_64.

        tail: fix tailing non seekable files on certain systems
        * src/tail.c (tail_bytes): On systems were blksize_t is unsigned
        and the same size or wider than off_t (android for example),
        our initialized (off_t) -1 would be promoted to unsigned before
        comparison, and thus fail to follow the appropriate path.
        * tests/tail-2/tail-c.sh: Add a test case.
        * NEWS: Mention the fix.
        This issue was introduced in commit v8.23-47-g2662702
        Reported at https://github.com/termux/termux-app/issues/233

        build: avoid build failure without sys/mtio.h
        * m4/jm-macros.m4: Check for the header.
        * src/dd.c: Avoid the workaround where the header
        is not available (on non glibc systems).
        * src/shred.c: Likewise.

        doc: reorganize ls -k and --time-style help
        * src/ls.c (usage): Clarify -k only applies to -s usage
        and directory 'total' lines.  Move the description
        of TIME_STYLE out of the option section as it was awkward
        to read and write there within 80 columns.

2017-12-10  Pádraig Brady  <P@draigBrady.com>

        doc: clarify numeric setuid handling in chmod man page
        * man/chmod.x: Update the information to state one can
        clear the setuid and setgid bits for directories numerically
        using an additional leading '0' or a leading '='.
        That has been supported since v8.15-64-g8931cdb.
        Fixes https://bugs.gnu.org/29390

        doc: shred: change 'truncate' to the more descriptive 'deallocate'
        * doc/coreutils.texi (shred invocation): s/truncate/deallocate/.
        * src/shred.c (usage): Likewise.
        Fixes https://bugs.gnu.org/29317

        doc: clarify that cp --force may recreate files
        * doc/coreutils.texi (cp invocation): The language used
        to describe recreating the file was a little confusing
        as it mentioned opening a removed file.
        Fixes https://bugs.gnu.org/29315

2017-12-04  Kamil Dudka  <kdudka@redhat.com>

        doc: fix default QUOTING_STYLE for %N format of stat(1)
        * doc/coreutils.texi (stat invocation): The default value
        of QUOTING_STYLE for the %N format of 'stat --printf' is
        'shell-escape-always'.
        Fixes https://bugs.gnu.org/29563

2017-12-02  Jean Delvare  <jdelvare@suse.de>

        tests: make ls/block-size more readable
        * tests/ls/block-size.sh: The output of the test was hard to read. Add
        comments saying what we are testing to make it easier to understand.

            Pádraig Brady  <P@draigBrady.com>

        tests: verify usage vs. getopt
        Verify that all options mentioned in usage are actually recognized
        by the program.

        * tests/misc/usage_vs_getopt.sh: Add test.
        * tests/local.mk (all_tests): Reference it.

        readlink: remove superfluous comma from usage output
        * src/readlink.c (usage): Remove ',' after --quiet option.

2017-11-29  Bernhard Voelker  <mail@bernhard-voelker.de>

        all: use consistent diagnostics for unknown long options
        Previously, e.g. cksum failed to output the offending unknown long
        option:
          $ cksum --unknown-opt
          cksum: invalid option -- '-'
          Try 'cksum --help' for more information.
        i.e., it tried to diagnose '-' as short option.
        Instead, it should diagnose the unknown long option:
          $ cksum --unknown-opt
          cksum: unrecognized option '--unknown-opt'
          Try 'cksum --help' for more information.

        * src/cksum.c (long_options): Add struct with null entry only.
        (main): Use it in the getopt_long call.

        test: fix issues with tests/cp/preserve-mode.sh
        * tests/cp/preserve-mode.sh: This was the only use of awk,
        which may not be available on the system resulting
        in an ineffective test.  Also the permissions bits for
        directories were not being checked at all.

        build: update gnulib submodule to latest
        * gnulib: Update with various build/test fixes.

        * src/timeout.c (main): Add short option character 'v' to getopt_long
        call.
        * tests/misc/timeout.sh: Run the test both for the long and the short
        option.

2017-11-25  Pádraig Brady  <P@draigBrady.com>

        dd: support iflag=direct with arbitrary sized files
        * src/dd.c (iread): Handle read error with a non-aligned
        file offset in the O_DIRECT case.  This is not an issue
        on XFS at least, but on EXT4 the final read will return
        EINVAL rather than the expected 0 to indicate EOF.
        * tests/dd/direct.sh: Test the iflag=direct case also.
        * NEWS: Mention the improvement.

2017-11-24  Pádraig Brady  <P@draigBrady.com>

        timeout: add --verbose to diagnose timeouts
        This is useful as handling in shell is complicated
        with the varying exit status in the --kill-after case.

        * src/timeout.c (main): Handle '-v' and store
        COMMAND for the diagnostic.
        (cleanup): Diagnose the signal name before sending.
        (usage): Document -v, --verbose.
        * doc/coreutils.texi (timeout invocation): Likewise.
        * tests/misc/timeout.sh: Add a test case.

        we can't determine the file size.
        * tests/tail-2/end-of-device.sh: Add a new root only test.
        * tests/local.mk: Reference the new test.
        * NEWS: Mention the improvement.
        Paul Eggert suggested using lseek() (rather than ioctl(BLKGETSIZE64)).

        doc: fix "Up" field of realpath usage examples
        Older versions of 'makeinfo' choke on a missing reference:

          ./doc/coreutils.texi:14177: `Realpath usage examples' has no Up field\
          (perhaps incorrect sectioning?).
          makeinfo: Removing output file `doc/coreutils.info' due to errors; \
          use --force to preserve.

        * doc/coreutils.texi (realpath invocation): Add a menu referencing
        the usage examples - introduced in v8.27-91-g7449f0d.

        XFS on systems with > 1MiB pages, or on file systems not
        supporting O_DIRECT, there would have been false failures.

2017-10-25  Pádraig Brady  <P@draigBrady.com>

        dd: fix nocache regions passed to posix_fadvise()
        Previously with oflag=direct the call to invalidate_cache()
        was not passed to the kernel, as it was less than a page size,
        and a subsequent call was not made to invalidate the pending space.
        Similarly with oflag=nocache the pending space at EOF was
        not invalidated.  Even though these amount to only a single page
        in the page cache it can be significant.  For example on
        XFS before kernel patch v4.9-rc1-4-g0ee7a3f, O_DIRECT files
        would have been read inefficiently if any pages were cached,
        even if they were already synced to storage.

        * src/dd.c (i_nocache_eof, o_nocache_eof): New bools used
        to control when we want invalidate_cache(,0) to clear to EOF.
        (cache_round): Use IO_BUFSIZE (currently 132KiB) to minimize
        calls to the relatively expensive advise function, rather
        than page_size.  This also makes it clear that while the
        kernel function operates on pages, this size is chosen for
        performance reasons.
        (invalidate_cache): Refactor to share more code between
        input and output paths. Use i_nocache_eof and o_nocache_eof
        rather than proxying off max_records.  Ensure we
        invalidate full pages when clearing to EOF as the kernel
        will ignore any non complete pages.  Fix the offset used
        for the output path.
        (dd_copy): Invalidate the cache of the input after the
        offset is updated, for consistency and so we don't try to
        invalidate before the start of the file.  When we read
        EOF on input, set flags so that we invalidate to EOF.
        (main): Invalidate to EOF in more cases, by depending
        on the i_nocache_eof and o_nocache_eof flags.
        * doc/coreutils.texi (dd invocation): Clarify the alignment
        and persisted caveats on the example applying "nocache"
        to part of a file.
        * tests/dd/nocache_eof.sh: A new test.
        * tests/local.mk: Reference the new test.
        * NEWS: Mention the bug fix.

        This was a latent issue that became significant with

        * src/stty.c (apply_settings): Refactor argument checking

        timeout: fix a small race that would ignore command exit
        This fixes a regression from commit v8.26-39-g2f69dba

        * src/timeout.c (block_cleanup_and_chld): Rename from block_cleanup

        timeout: fix regression when invoked with blocked SIGCHLD
        We inherit the signal mask from our parent process,
        therefore ensure SIGCHLD is not blocked.

        If SIGCHLD is blocked, sigsuspend() won't be interrupted
        when the child process exits and we hang until the timeout (SIGALRM).

        build: reinstate distribution of man pages
        man pages change little between systems,
        so falling back to distributed pages make sense
        when cross compiling or lacking perl.

        * man/local.mk: Add all man pages to EXTRA_DIST
        so that they're distributed in the generated tarball.
        Use the dummy-man page generator if cross compiling.
        Set TZ to avoid a distcheck failure where man pages
        used a diffent month than those rebuilt (with a .timestamp).
        * man/dummy-man: Only fall back to generating a stub

        runcon: revert "disable use of the TIOCSTI ioctl"
        This reverts commit v8.27-97-g8cb06d4 because
        the setsid() fallback was not implemented correctly
        and disabling the ioctl was not a complete solution
        to the security issue of the child being passed
        the tty of the parent.

        Given runcon is not really a sandbox command,
        the advice is to use `runcon ... setsid ...`
        to avoid this particular issue.

        df: avoid stat() for dummy file systems with -l
        When systemd is configured to automount a remote file system - see
        'man systemd.automount(5)', then the mount point is initially
        mounted by systemd with the file system type "autofs".
        When the resource is used later on, then the wanted file system is
        mounted over that mount point on demand.
        'df -l' triggered systemd to mount the file system because it called
        stat() on the mount point.
        Instead of single-casing "autofs" targets, we can avoid stat()ing
        all dummy file systems (which includes "autofs"), because those are
        skipped later on in get_dev() anyway.

        *src/df.c (filter_mount_list): Also skip dummy file systems unless
        the -a option or a specific target are given.
        * NEWS: Mention the fix.

        ptx: fix some integer overflow bugs
        Problem reported by Lukas Zachar at:
        http://bugzilla.redhat.com/1482445
        * src/ptx.c (line_width, gap_size, maximum_word_length)
        (reference_max_width, half_line_width, before_max_width)
        (keyafter_max_width, truncation_string_length, compare_words)
        (compare_occurs, search_table, find_occurs_in_text, print_spaces)
        (fix_output_parameters, define_all_fields):
        Use ptrdiff_t, not int, for object offsets and sizes.
        (WORD, OCCURS): Use ptrdiff_t, not short int.
        (WORD_TABLE, number_of_occurs, generate_all_output):
        Prefer ptrdiff_t to size_t where either will do.
        (total_line_count, file_line_count, OCCURS, fix_output_parameters)
        (define_all_fields):
        Use intmax_t, not int, for line counts.
        (DELTA): Remove.  All uses changed.
        (OCCURS, find_occurs_in_text, fix_output_parameters):
        Use int, not size_t, for file indexes.
        (tail_truncation, before_truncation, keyafter_truncation)
        (head_truncation, search_table, define_all_fields)
        (generate_all_output):
        Use bool for booleans.
        (digest_word_file, find_occurs_in_text):
        Use x2nrealloc instead of checking for overflow by hand.
        (find_occurs_in_text, fix_output_parameters, define_all_fields):
        Omit unnecessary cast.
        (fix_output_parameters): Don�<80><99>t assume integers fit in 11 digits.
        (fix_output_parameters, define_all_fields):
        Use sprintf return value rather than calling strlen.
        (define_all_fields): Do not rely on sprintf to generate a string
        that may contain more than INT_MAX bytes.
        (main): Use xstrtoimax, not xstrtoul.
        Use xnmalloc to catch integer overflow.

        nohup: simplify by using fcntl
        * src/nohup.c: Do not include cloexec.h.
        (main): Use fcntl rather than dup + set_cloexec_flag.

        sort: use pthread_sigmask, not sigprocmask
        POSIX says sigprocmask has unspecified behavior in a multithreaded
        program like �<80><98>sort�<80><99>.
        * src/sort.c (pthread_sigmask) [GNULIB_defined_pthread_functions]:
        New macro, for use when �<80><98>sort�<80><99> is not multithreaded.
        (cs_enter, cs_leave): Use it.  Pass address, not value, as
        this is typically a tad faster.  All callers changed.

        sort: minor cleanups
        * src/sort.c (move_fd): Rename from move_fd_or_die,
        since it no longer can die.

        sort: file descriptor discipline
        Use O_CLOEXEC when creating file descriptors, so that subsidiary
        processes do not inherit file descriptors that they do not need.
        This is helpful for �<80><98>sort�<80><99>, as it is a multithreaded program that
        forks and execs.
        * bootstrap.conf (gnulib_modules): Add mkostemp, open, pipe2.
        * src/sort.c (create_temp_file): Open temporary file with O_CLOEXEC.
        (stream_open): Open the stream with O_CLOEXEC.
        (pipe_fork): Create the pipe with O_CLOEXEC.
        (check_output): Open the output file with O_CLOEXEC.
        (main): Use xfopen/xfclose to handle --files0-from, so that
        O_CLOEXEC is used properly.  This is simpler anyway.
        * tests/misc/sort-files0-from.pl: Adjust to change in diagnostic
        wording.

        kill: fix signal number to name lookup on AIX
        * src/operand2sig.c (operand2sig): AIX uses a different bit pattern
        in the returned status from the wait() functions and from shells.
        Therefore hardcode the selection of the lower bits of the number.
        * NEWS: Mention the fix.

        build: use the appropriate single file include option with xlc
        * configure.ac: Set USE_XLC_INCLUDE when __xlc__ is defined.
        * src/local.mk: Use it to select the appropriate include option.
        Reported by Michael Felt.

        tests: avoid false failures on AIX
        * tests/ln/sf-1.sh: Limit the symlink size to 1MiB
        to avoid memory exhaustion seen on NFS on AIX, giving:
          + printf '%0*d' 4294967296 0
          + ./tests/ln/sf-1.sh: line 38: printf: warning: 0: Result too large
        * tests/id/setgid.sh: Skip the test when the adjusted gid
        would equal 4294967295, as that's reserved on AIX.
        Reported by Michael Felt.

        sort: handle musl locale differences in --debug reporting
        * src/sort.c (main): Don't assume hard_LC_COLLATE implies
        a successful setting of the locale as musl defaults to
        UTF8 when failing to set the specified locale.
        * tests/misc/sort-debug-warn.sh: Adjust for the now
        separated locale debug info and map the musl specific
        message back to the common case.
        Addresses https://bugs.gnu.org/28054

        seq: produce consistent error messages upon write error
        * src/seq.c (io_error): Use the same error message as would
        be generated at exit time when closing the stdout stream.
        The inconsistency was added with commit v8.25-26-gc92585b.
        This was noticed due to an inconsistency in the expected
        error message generated by seq on musl libc.
        Addresses https://bugs.gnu.org/28054

        tests: fix false failure with large printf formats
        * tests/misc/printf-surprise.sh: With musl libc the
        large printf format does succeed, outputting data.
        To avoid SIGPIPE being generated we ignore that signal
        and then handle the subsequent EPIPE error.

        Building with warnings enabled and latest gcc would evoke build
        failure without these changes.  Disable the following in coreutils
        proper: -Wformat-overflow=2 -Wformat-truncation=2, and

        (copy_internal): Use it.  Fail instead of falling back on numbered
        backups when it looks like the backup will overwrite the source.

        to avoid races with numbered backups.
        * tests/cp/backup-is-src.sh, tests/mv/backup-is-src.sh:
        Adjust to match new behavior.

        shred: avoid rename race
        Use renameat2 to avoid a rename race condition, on recent-enough
        GNU/Linux.
        * bootstrap.conf (gnulib_modules): Add renameat2.

        groups: do not exit early
        Most programs take care to operate on all command-line-specified
        operands before exiting.  That is an important feature that allows

        characters fitting in a given byte offset.
        (docolon): Report matched logical characters instead of bytes.
        (eval6): For length/substr/index operations, use logical characters
        instead of bytes by calling the above new functions.
        * tests/misc/expr.pl: Repeat all tests with non-C locale to detect any

        maint: avoid spurious "make distcheck" failure
        When the generated file, doc/constants.texi, happens to be older than
        doc/coreutils.info, it will not be updated until/unless its generated
        contents change.  This is due to way that rule is careful to update
        the file, to avoid provoking a pointless rerunning of makeinfo.

        Note that this does not happen when one first runs "make distclean",
        as recommended in README-release.  However, I sometimes run it as
        a more-rigorous "make check", and shouldn't have to manually run
        "make distclean" first, in that case.

        Before this change, one could reproduce the failure by running
        `touch -dyesterday doc/constants.texi && make distcheck`.  It would
        fail with "makeinfo: could not open ../../doc/coreutils.info-t
        for writing: Permission denied"

        split: ensure input is processed when filters exit early
        commit v8.25-4-g62e7af0 introduced the issue as it
        broke out of the processing loop irrespective of
        the value of new_file_flag which was used to indicate
        a finite number of filters or not.

        For example, this ran forever (as it should):
          $ yes | split --filter="head -c1 >/dev/null" -b 1000
        However this exited immediately due to EPIPE being propagated
        back through cwrite and the loop not considering new filters:
          $ yes | split --filter="head -c1 >/dev/null" -b 100000

        Similarly processing would exit early for a bounded number of
        output files, resulting in empty data sent to all but the first:
          $ truncate -s10T big.in
          $ split --filter='head -c1 >$FILE' -n 2 big.in
          $ echo $(stat -c%s x??)
          1 0

        I was alerted to this code by clang-analyzer,
        which indicated dead assigments, which is often
        an indication of code that hasn't considered all cases.

        * src/split.c (bytes_split): Change the last condition in
        the processing loop to also consider the number of files
        before breaking out of the processing loop.
        * tests/split/filter.sh: Add a test case.

        maint: use xsetmode, not xfreopen
        This fixes a bug noted by Eric Blake.  Code was using xfreopen to
        change files to binary mode, but this fails for stdout when in
        append mode.  Such code should use xsetmode instead.  This affects
        only the port on platforms like MS-Windows which distiguish text
        from binary I/O.

        ln: replace destination links more atomically
        If the file B already exists, commands like 'ln -f A B' and
        'cp -fl A B' no longer remove B before creating the new link.
        Instead, they arrange for the new link to replace B atomically.
        This should fix a race condition reported by Mike Crowe (Bug#25680).

        timeout: fix race possibly terminating wrong process
        The race is unlikely, as timeout(1) needs to receive a signal
        in the few operations between waitpid() returning and exit().
        Also the system needs to have reallocated the just released pid
        in this time window.

        Previously we never disabled the signal handler that sent
        the termination signal to the "child" pid.  However once waitpid()
        has reaped the child, the system is free to allocate that pid,
        so we must ensure we don't process any further signals.

        * build-aux/gen-lists-of-programs.sh: Build timeout(1) optionally...
        * configure.ac: ...predicated on sigsuspend() being available.
        * src/timeout.c (block_cleanup): A new function to ensure the
        cleanup() handler is disabled after waitpid has returned.
        (main): Use sigsuspend() to wait with cleanup() enabled but
        disabled once it returns, and thus disabled for the waitpid() call.
        (monitored_pid): Change to the more accurate pid_t.
        * NEWS: Mention the fix.

        tests: fix tail test race causing false failure
        * tests/tail-2/retry.sh: The replacement of the "missing" directory
        is not atomic, and therefore tail(1) can take a different path,
        especially if there is a delay between the rmdir(2) and creat(2).
        This is noticeable for example with `make coverage` because in
        that case the coverage files written by rmdir(1) on exit,
        induce a significant delay thus triggering the issue.

        tail: fix erroneous status about 'giving up' on file
        * src/tail.c (recheck): Set f->ignore before we
        use it to show the appropriate error.
        * tests/tail-2/retry.sh: Ensure the "giving up" message
        is not presented.
