A replacement getgroups is now guaranteed to exist, but it may
fail with ENOSYS. mgetgroups is moved to gnulib, and now takes
gid_t instead of GETGROUPS_T (but setgroups still needs GETGROUPS_T).
* gnulib: Update to latest.
* gl/modules/mgetgroups: Delete, moved to gnulib.
* gl/m4/mgetgroups.m4: Likewise.
* gl/lib/mgetgroups.h: Likewise.
* gl/lib/mgetgroups.c: Likewise.
* src/group-list.c (print_group_list): Adjust callers.
* src/id.c (print_full_info): Likewise.
cat, head, ptx, shuf, tac, tail, tee, tr, and uniq used freopen
on stdout, and were potentially vulnerable. dircolors, du, and
tsort only used it on stdin, which is unaffected by freopen_safer,
but this covers all uses for consistency.
* cfg.mk (sc_require_stdio_safer): New rule.
* gl/modules/xfreopen (Depends-on): Add freopen-safer.
* gl/lib/xfreopen.c (includes): Use stdio--.h.
* src/ptx.c (includes): Likewise.
* src/shuf.c (includes): Likewise.
* src/uniq.c (includes): Likewise.
* src/dircolors.c (includes): Likewise.
* src/du.c (includes): Likewise.
* src/tsort.c (includes): Likewise.
In glibc 2.11 and gnulib, gen_tempname added a parameter
suffixlen (unfortunately, it is typed as int rather than
size_t, for historical compatibility to a poor choice by BSD).
* gnulib: Import latest changes.
* gl/lib/tempname.h.diff: Accommodate new suffixlen parameter.
* gl/lib/tempname.c.diff (check_x_suffix): Allow for X in suffix
beyond x_suffix_len.
(gen_tempname_len): Add suffixlen parameter.
(__gen_tempname): Update caller.
* src/mktemp.c (mkstemp_len, mkdtemp_len): Update callers.
Diffs are more robust than wholesale replacement, because bootstrap
will inform us of any incompatible changes made in upstream gnulib.
* gl/lib/tempname.h: Change...
* gl/lib/tempname.h.diff: ...to diff.
* gl/lib/tempname.c: Change...
* gl/lib/tempname.c.diff: ...to diff.
* gl/lib/mbsalign.c (mbsalign): Mark unused parameter.
* bootstrap.conf (gnulib_modules): Remove obsolete
rename-dest-slash.
* gnulib-tests/Makefile.am (AM_CFLAGS): Reduce set of warnings for
gnulib tests.
* gl/modules/rename-tests.diff (Makefile.am): New file, to add
LIBINTL to LDADD, since we avoid canonicalize-lgpl module.
* gl/lib/regcomp.c.diff (regerror, calc_next)
(build_collating_symbol, parse_bracket_element, build_equiv_class)
(free_tree): Mark unused parameters.
* gl/lib/regex_internal.h.diff (re_string_elem_size_at): New file,
to mark unused parameters.
* gl/lib/printf-args.c.diff (PRINTF_FETCHARGS): New file, to avoid
type mismatch.
* gl/lib/vasnprintf.c (VASNPRINTF): New file, to avoid shadowing
local variable name.
* .gitignore: Ignore temporary build artifacts.
* configure.ac (GNULIB_WARN_CFLAGS): Define.
* lib/Makefile.am (AM_CFLAGS): Use $(GNULIB_WARN_CFLAGS)
rather than $(WARN_CFLAGS) and add $(WERROR_CFLAGS).
* gl/lib/regcomp.c.diff: New file.
* gl/lib/regex_internal.c.diff: New file.
* gl/lib/regexec.c.diff: New file.
* src/mktemp.c (mkstemp_len, mkdtemp_len): Update callers of
gen_tempname_len.
* gl/lib/tempname.c, gl/lib/tempname.h: Rebase against recently
API-modified copy of tempname module in gnulib.
Reported by Lluís Batlle.
* gl/lib/selinux-at.c: Remove file.
* gl/lib/selinux-at.h: Likewise.
* gl/modules/selinux-at: Likewise.
* gnulib: update to latest, to get the new module.
Steven Parkes reported that `id -G $USER` went into an infinite loop
on Darwin systems for users in more than 10 groups:
http://bugs.gentoo.org/show_bug.cgi?id=264007
* gl/lib/mgetgroups.c (mgetgroups): Work around buggy getgrouplist
implementations that don't update the required size correctly,
by doubling the result buffer and retrying. Also return the
parameter updated by getgrouplist rather than its return value,
as the documentation doesn't actually state the number of groups
stored is returned by getgrouplist.
* tests/misc/id-groups: Add test to exercise this logic
* tests/Makefile.am: Reference new test
* NEWS: Mention the fix
* THANKS: Update
Suggestion from Steven Schveighoffer at:
http://savannah.gnu.org/patch/?6797
to greatly speed up the random passes done by shred.
* gl/lib/randread.c: Default to using the internal
pseudorandom generator, rather than reading /dev/urandom
* src/shred.c (usage): remove mention of /dev/urandom
* src/shuf.c (usage); ditto
* src/sort.c (usage): ditto
* doc/coreutils.text: Document the new behaviour
for aquiring random data.
Reported by Samuel Thibault and Stéphane Raimbault, as the glibc fr_FR
locale has recently changed to use the official but variable width
abbreviated month names. Other glibc locales also have variable widths.

* NEWS: Mention the fix
* gl/lib/mbsalign.c: A new module to align and truncate a
string in a specified number of screen cells, while handling
multi-byte characters appropriately.
* gl/lib/mbsalign.h: Ditto
* gl/modules/mbsalign: Ditto
* bootstrap.conf: Reference the new module
* src/ls.c (abmon_init): New function, precompute the abbreviated
months aligned left in a minimum width column <= 5 screen cells.
(align_nstrftime): New function, replace the first %b in the
format specification to strftime with the precomputed month string.
Note using the cached month strings speeds up `ls -lU` by around 17%
on glibc-2.7-2 on linux at least. Also if we implement this function
using heap storage rather than automatic storage, and use snprintf
instead of strcpy, ls will slow down by 2% and 1% respectively
(i.e. a net gain of 14% rather than 17%).
* tests/ls/abmon-align: A new test to test ls alignment for
various formats and locales
* tests/Makefile.am: Reference the new test
* gl/lib/argv-iter.h (_ATTRIBUTE_NONNULL_): Don't assume C99 variadic
macros are portable yet; needed for at least IRIX/MIPSpro.
* THANKS: Update.
Reported by Stuart Shelton.
* gl/lib/mgetgroups.c: Avoid -Wsign-compare warning by using unsigned
types for the parameters of the new function realloc_groupbuf().
mgetgroups() was refactored to use this function rather than
explicitly allocating and copying from automatic storage itself.
* src/group-list.c: Use int rather than size_t as variable is
used in signed comparisons.
* src/id.c: ditto.
* gl/lib/argv-iter.h: New file.
* gl/lib/argv-iter.c: New file.
* gl/modules/argv-iter: New file.
With a suggestion for improved memory management by Pádraig Brady.
* gl/lib/base64.c (base64_decode_ctx): If no context structure was passed in,
treat newlines as garbage (this is the historical behavior). Formerly
base64_decode.
(base64_decode_alloc_ctx): Formerly base64_decode_alloc.
* gl/lib/base64.h (base64_decode): Macro for four-argument calls.
(base64_decode_alloc): Likewise.
* src/base64.c (do_decode): Call base64_decode_ctx instead of base64_decode.

* gl/lib/mgetgroups.c (mgetgroups) [N_GROUPS_INIT]: Rename enum.
Use a larger value.
Update *groups only upon success.
Iterate upon failed getgrouplist.
* gl/m4/mgetgroups.m4: Check for getgrouplist.
* gl/lib/mgetgroups.c (mgetgroups): Use getgrouplist, if available.
* TODO: Remove the item about switching to getgrouplist.
* NEWS: mention this
* src/system.h (__attribute__): Remove the __STRICT_ANSI__ disjunct.
It has been unnecessary since approximately gcc-2.6, and now, leaving
it would cause gcc -Werror -ansi to fail to compile csplit.c.
* gl/lib/randread.c (__attribute__): Likewise.
* src/install.c (setdefaultfilecon): Call matchpathcon_init_prefix,
to mitigate what would otherwise be a large performance hit due to
the use of matchpathcon.
Dan Walsh suggested the use of matchpathcon_init_prefix.
* gl/lib/se-selinux.in.h (matchpathcon_init_prefix): Define.

* gl/modules/tempname (Depends-on): Add randint and stdbool.
* gl/lib/tempname.c: Include randint.h and stdbool.h.
(uint64_t): Remove definition. Not needed.
[_LIBC] (RANDOM_BITS): Remove this block, now that we have proper random bits.
(check_x_suffix): New function.
(gen_tempname_len): Rename from __gen_tempname.
Add a parameter, x_suffix_len, telling how many X's there must be at
the end of the template.
Use pseudo-random numbers all the way, rather than adding 7777
from one iteration to the next.
(__gen_tempname): New function, to call gen_tempname_len, requiring a
suffix length of 6.
* gl/lib/tempname.h: Add prototype for gen_tempname_len.
Signed-off-by: Jim Meyering <meyering@redhat.com>
* bootstrap.conf (gnulib_modules): Remove file-set, now that
it's in gnulib, and the canonicalize module requires it there.

(triple_compare, triple_free): Functions from copy.c.
* gl/lib/hash-triple.h (struct F_triple): Define. From copy.c.
Add prototypes.
* gl/modules/file-set: New module.
* gl/modules/hash-triple: New module.
* src/Makefile.am (copy_sources): New variable.
(ginstall_SOURCES, cp_SOURCES, mv_SOURCES): Use it.
* src/copy.c: Include hash-triple.h.
No longer include hash-pjw.h.
(copy_internal): Don't pass a NULL third argument to record_file,
since that function no longer accepts that.
(record_file): Move this function to file-set.c.
Along the way, remove the code to allow a NULL stat-buffer pointer.
Adjust sole caller.
(seen_file): Move this function to file-set.c.
(struct F_triple): Move declaration to hash-triple.h.
(triple_compare, triple_free, triple_hash, triple_hash_no_name):
