* NEWS: Record release date.

* tests/misc/env-S.pl: `env -i env` will call the system env
due to the path being cleared, so pass the absolute path
of our env binary under test to avoid that.  This was seen
to be an issue on Guix where /usr/bin/env was not available.

* src/basenc.c (z85_decode_ctx_init): Ensure we're working
with unsigned, as otherwise ubsan triggers with:
  src/basenc.c:767:18: runtime error: signed integer overflow:
  43 * 52200625 cannot be represented in type 'int'
(z85_encode): Likewise to avoid the usban error:
  src/basenc.c:630:26: runtime error:
  left shift of 134 by 24 places cannot be represented in type 'int'

* tests/misc/timeout-parameters.sh: Split the large timeout
handling to ...
* tests/misc/timeout-large-parameters.sh: ... here, so that
the 3 second delay is contained in its own test, and if
the test is skipped due invalid handling within timeout(1),
it will be more apparent.
Also adjust the check so we skip whenever the kernel timer
fires immediately, to handle the buggy OpenIndiana 11 kernel also.
Reported by Bruno Haible.

* tests/du/8gb.sh: Add a timeout around:
`dd bs=1 seek=8G of=big < /dev/null`

* init.cfg (require_bash_as_SHELL_): A new function to replace
SHELL for the current test, with bash if available.
This is useful on OpenIndiana 11 where /bin/sh was seen
to have races in handling of SIGPIPE.
* tests/misc/seq-epipe.sh: Use the new function to enforce bash.
* tests/misc/env-signal-handler.sh: Likewise.
Reported by Bruno Haible

* tests/ls/stat-free-color.sh: Check for the availability
of various stat calls individually, and add statx() and fstatat64()
to the list to check.  Fix the stat counting logic to
ignore lines like "+++ exited with 0 +++".
* tests/ls/stat-free-symlinks.sh: Check syscalls other than stat().

* init.cfg (gcc_shared_libs_): New variable.
(gcc_shared_): Use it, instead of hardcoding -ldl.
(require_gcc_shared_): Determine the suitable value
for gcc_shared_libs_.

* tests/ls/stat-free-symlinks.sh: s/|| fail/|| fail=1/.
* tests/misc/tee.sh: Likewise.
* tests/touch/relative.sh: Likewise.
* cfg.mk (sc_prohibit_or_fail): A new syntax-check to avoid this.

With these adjustments, all tests pass on macOS Catalina.

* tests/dd/sparse.sh: Adjust so that systems like apfs that
don't create holes < 16 MiB do not fail erroneously.
* tests/touch/trailing-slash.sh: Darwin was seen to dereference
symlinks to files when given a trailing slash, so avoid
that particular case.

* tests/misc/csplit-io-err.sh: Limit the effect of the fwrite
override to streams != stderr, as fwrite is in the error() path there.

* configure.ac: Reenable distribution of gzip-compressed
tarballs, for Guix bootstrapping reasons as discussed at:
https://lists.gnu.org/r/coreutils/2020-02/msg00042.html
* THANKS.in: Remove me, as now a committer.
* NEWS (Build-related): Mention this.

* .gitignore: s|*/.deps/|.deps|

* Makefile.am: Update the oldest documented version
to 8.23 which is now about 5 years old.

If the current directory has been removed, then "ls" confusingly
produced no output and no error message, indistinguishable from
running on an empty directory.

* src/ls.c (print_dir): Report ENOENT on GNU/Linux if readdir
finds no directory entries at all, not even "." or "..",
and a recheck with the getdents syscall returns ENOENT.
We recheck with getdents() as POSIX states that
"The directory entries for dot and dot-dot are optional".
* tests/ls/removed-directory.sh: New file.
* tests/local.mk (all_tests): Add new test.
* NEWS: Mention the change in behavior.
Reported by Owen Thomas.

* bootstrap.conf: Adjust for changes to fchmodat and fchownat,
which are now separated from chmodat and chownat respectively.

* src/blake2/blake2-impl.h: Sync load16() implementation,
which doesn't change code generation.
Also leverage (builtin) memcpy to more efficiently
move data on little endian systems,
giving a 2% win with GCC 9.2.1 on an i3-2310M.

* src/longlong.h: Sync changes from:
https://gmplib.org/repo/gmp/log/tip/longlong.h
mips64: Provide r6 asm code as default expression yields.
arm32: Define sub_ddmmss separately for non-thumb (no rsc instruction).
powerpc: Add "CLOBBER" descriptions for some registers.
x86: Fix criterion for when to use mulx in umul_ppmm.

* src/stat.c: Add magic constants for "binderfs", "dma-buf-fs",
"erofs", "ppc-cmm-fs", and "z3fold".
* NEWS: Mention the improvement.

strcoll() is only significant to uniq(1) if it returns 0,
and it generally only does so with buggy locales or mismatched
locales and data.  Some systems may have strcoll()
return 0 for equivalent normalized unicode forms,
but for consistency across platforms strcoll() is avoided.
The various cases are defined in the new test.
This is consistent with newer POSIX standards as discussed at:
https://www.austingroupbugs.net/view.php?id=963

* src/uniq.c: s/xstrcoll/memcmp/.
* tests/local.mk: Reference the new test.
* tests/misc/uniq-collate.sh: Add a new test.
* NEWS: Mention the change in behavior.
Fixes https://bugs.gnu.org/38627

* src/stat.c (usage): Mention permission bits rather than
"access" so there is no confusion with ACLs etc.
Also indicate we output the file type with '%A'.
* doc/coreutils.texi (stat invocation): Likewise.
Also indicate '%A' is similar to `ls -ld` output.
Addresses https://bugs.gnu.org/39613

* tests/cp/preserve-gid.sh: s/-l/-L/.
Reported by Kamil Dudka

* tests/cp/preserve-gid.sh: If configured with --enable-single-binary
copy the coreutils single binary, instead of the cp one-line launcher.

Discussed at https://bugzilla.redhat.com/1800597
Fixes https://bugs.gnu.org/39485

* configure.ac: Restrict lines to 80 chars.

* configure.ac (GNULIB_WARN_CFLAGS): Add -Wno-return-local-addr
to avoid FP warning about careadlinkat.c. Discussed starting in
https://lists.gnu.org/r/coreutils/2020-02/msg00006.html

Pick up recent build fixes to avoid sysctl.h inclusion on glibc systems,
restrict the max file size supported by read-file to PTRDIFF_MAX,
and to avoid a -Werror=unused failure in test-canonicalize.

* tests/cp/proc-short-read.sh: Switch to using /proc/cpuinfo,
rather than /proc/kallsyms which was seen to vary in some cases.
Fixes https://bugs.gnu.org/39357

Since v6.10-21-ged5c4e77 `rmdir --ignore-fail-on-non-empty`
had reversed the failure status for directories that failed
to be removed for permissions reasons.  I.E. it would have
returned a failure status for such non empty dirs, and vice versa.

* src/rmdir.c (errno_may_be_non_empty): Rename from the
more confusing errno_may_be_empty(), and remove the EEXIST
case (specific to Solaris), which is moot here since
handled in errno_rmdir_non_empty().
(ignorable_failure): Fix the logic error so that
_non_ empty dirs are deemed to have ignorable failures.
(main): Fix clobbering of errno by is_empty_dir().
(remove_parents): Likewise.
* tests/rmdir/ignore.sh: Add a test case.
* THANKS.in: Add reporter who fixed the errno handling.
* NEWS: Mention the bug fix.
Fixes https://bugs.gnu.org/39364

* configure.ac: Add -Wno-vector-operation-performance to suppress the
following gcc-9.2 error in gl/lib/randperm.c:
  error: vector operation will be expanded piecewise

* src/uname.c: Avoid unneeded header with GLIBC,
which has been deprecated since glibc-2.30.
* src/uptime.c: Likewise.

* src/ls.c (usage): Reorganize help for --time,
and add description for --time=birth.
(do_statx): Store btime in mtime if available.
(get_stat_btime): A new function to read the creation time
from the appropriate stat structure member.
(cmp_btime): A new function to compare birth time.
(print_long_format): Output '?' when birth time unavailable.
* doc/coreutils.texi: Document --time={birth,creation}.
* tests/local.mk: Reference the new test.
* tests/ls/birthtime.sh: Add a new test.
* NEWS: Mention the new feature.

* src/yes.c (main): Convert for loop to do-while in order to indicate
that the loop will be run at least once.
This avoids the following warning after the second loop:
src/yes.c:110:20: error: writing 1 byte into a region of size 0

* .gitignore: Add file newly generated by gnulib commit 49e78fc

* configure.ac: Set --with-openssl=auto-gpl-compat as the default,
so that openssl is used for md5sum etc., with openssl >= 3,
which is newly licensed under ASL v2.
* gnulib: Update to include "auto-gpl-compat" support.

* bootstrap.conf: Depend on the new module split from xstrtol.
* src/df.c: Include "xstrtol-error.h" for xstrtol_fatal.
* src/du.c: Likewise.
* src/ls.c: Likewise.
* src/od.c: Likewise.
* src/pr.c: Likewise.
* src/sort.c: Likewise.

Run "make update-copyright" and then...

* gnulib: Update to latest with copyright year adjusted.
* tests/init.sh: Sync with gnulib to pick up copyright year.
* bootstrap: Likewise.
* tests/sample-test: Adjust to use the single most recent year.

* doc/coreutils.texi (sleep invocation): Add an example to demonstrate
how to use the floating-point and the scientific notation to sleep
for sub-second times, e.g. milli-, micro- and nanoseconds.

  https://lists.gnu.org/r/coreutils/2019-12/msg00005.html

* cfg.mk (old_NEWS_hash): Regenerate after commit v8.31-56-gc1e19656.

* src/chcon.c (main): Skip call of security_check_context()
in case SELinux is disabled to avoid unnecessary failure.

Bug: https://bugzilla.redhat.com/1777831

* doc/sort-version.texi (Minus/Hyphen and Colon characters):
Rename from “Minus/Hyphen @samp{-} and Colon @samp{:} characters”,
as texi2any 6.6 complains about colons in node names.
