new snapshot available: coreutils-8.12.178-df9cd

[Jim Meyering]

Wow.  There have been nearly 1000 commits in *gnulib* since coreutils-8.12.
With 178 in coreutils proper, that is well above average[*].
If all goes well, I'll release coreutils-8.13 early next week,
so please beat this up (i.e., test) on a whatever systems you can.

A first for this snapshot, I've Cc'd the brand new platform-testers
mailing list: https://lists.gnu.org/mailman/listinfo/platform-testers

Here's the NEWS, followed by git-shortlog output, followed
by a summary of commits per release since 6.9.
I've omitted the 969 lines of gnulib's shortlog output.

===========================================================================

** Bug fixes

  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]

** 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.

** New features

  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

  cp and ls now support HP-UX 11.11's ACLs, thanks to improved support
  in gnulib.

  df now supports disk partitions larger than 4 TiB on MacOS X 10.5
  or newer and on AIX 5.2 or newer.

  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.

** Build-related

  Changes inherited from gnulib address a build failure on HP-UX 11.11
  when using /opt/ansic/bin/cc.

===========================================================================
Wondering about average commits per release, I wrote this tiny script:

#!/bin/sh
prev=
{ git tag | grep '^v' | sort -V; echo HEAD; } | \
  while read v; do
    printf $v
    test -z $prev && { echo; prev=$v; continue; }
    n=$(git rev-list $prev..$v|wc -l)
    printf "\t%3d\n" $n
    prev=$v
  done
exit

----------------------

Here's its output for coreutils:

    v6.9
    v6.9.89 381
    v6.9.90  68
    v6.9.91  15
    v6.9.92  27
    v6.10    12
    v6.11   201
    v6.12   112
    v7.0    226
    v7.1    195
    v7.2     90
    v7.3     72
    v7.4     11
    v7.5    135
    v7.6     82
    v8.0     66
    v8.1    130
    v8.2     39
    v8.3     59
    v8.4     15
    v8.5    103
    v8.6    200
    v8.7     37

    HEAD    178

So, yes, "178" is above the average (for the above subset) of 97.4.
