2016-11-27shred,sort: ensure faster unaligned access to rand modulePádraig Brady
glibc has changed the public define from _STRING_ARCH_unaligned to _STRING_INLINE_unaligned as per https://sourceware.org/bugzilla/show_bug.cgi?id=19462 * gl/lib/rand-isaac.c: Cater for both defines. * gl/lib/randread.c: Likewise. * src/system.h: Update commented out code.
2016-11-07maint: refactor printing of backup suffix --helpPádraig Brady
* src/system.h (emit_backup_suffix_note): A new function to output the backup suffix info. The strings are unchanged, so translations are not impacted. * src/cp.c (usage): Use the new function. * src/ln.c (usage): Likewise. * src/mv.c (usage): Likewise. * src/install.c (usage): Likewise.
2016-09-11pinky,who: remove redeclarations of ttynameGeorge Burgess IV
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.
2016-01-24build: avoid dynamic linking issue on Solaris sparcPádraig Brady
Solaris Studio 12 on sparc (not x86) will not remove unused functions, thus leaving a reference to an undefined program_name symbol from emit_try_help(). * src/system.h (emit_try_help): Change from an inline function to a macro, so that the inline function is not actually defined in libstdbuf.c. Fixes http://bugs.gnu.org/22430
2016-01-13join,sort,uniq: with -z, treat '\n' as a field separatorPádraig Brady
* NEWS: Mention the change in behavior. * doc/coreutils.texi (newlineFieldSeparator): A new description, referenced from ({join,sort,uniq} invocation). * src/system.h (field_sep): A new inline function to determine if a character is a field separator. * src/join.c (usage): s/whitespace/blank/ to be more accurate wrt which characters are field separators. (xfields): s/isblank/field_sep/. * src/sort.c (inittables): Likewise. * src/uniq.c (find_field): Likewise. * tests/misc/join.pl: Adjust -z test, and add a test/example for processing the whole record with field processing. * tests/misc/sort.pl: Add -z test cases, including case with '\n'. * tests/misc/uniq.pl: Add -z -f test case with \n.
2016-01-01maint: update all copyright year number rangesPádraig Brady
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.
2015-11-04all: avoid quoting file names when possiblePádraig Brady
Quote file names using the "shell-escape" or "shell-escape-always" methods, which quote as appropriate for most shells, and better support copy and paste of presented names. The "always" variant is used when the file name is embedded in an error message with surrounding spaces. * cfg.mk (sc_error_shell_quotes): A new syntax check rule to suggest quotef() where appropriate. (sc_error_shell_always_quotes): Likewise for quoteaf(). * src/system.h (quotef): A new define to apply shell quoting when needed. I.E. when shell character or ':' is present. (quoteaf): Likewise, but always quote. * src/*.c: Use quotef() and quoteaf() rather than quote() where appropriate. * tests/: Adjust accordingly.
2015-10-27copy,dd: simplify and optimize NUL bytes detectionPádraig Brady
* src/factor.c: Move LIKELY() definition to... * src/system.h: ...here. (is_nul): Reimplement with a version that doesn't require a sentinel after the buffer, and which calls down to (the system optimized) memcmp. Performance analyzed at http://rusty.ozlabs.org/?p=560 * src/dd.c (alloc_obuf): Simplify the is_nul() call by not needing to write the sentinel. * src/copy.c (sparse_copy): Likewise. (copy_reg): Simplify the buffer allocation by avoiding consideration of the sentinel in the buffer size calculation.
2015-05-26maint: remove sys/types.h include order checkPádraig Brady
* src/system.h: This was inadvertently ineffective due to a typo in commit v8.9-10-ge1aaf89 (Jan 2011), but has not caused any issues, so remove.
2015-05-10build: rewrite is_ENOTSUP without an #if directivePaul Eggert
* src/system.h (is_ENOTSUP): Avoid in-function #if directive.
2015-05-09build: avoid a warning form gcc's new -Wlogical-opJim Meyering
Without this change, very recent gcc (e.g., version 6.0.0 20150509) would print the following when configured with --enable-gcc-warnings: src/copy.c:165:30: error: logical 'or' of equal expressions \ [-Werror=logical-op] && (errno == EOPNOTSUPP || errno == ENOTSUP || errno == ENOSYS)) ^ * src/system.h (is_ENOTSUP): New function. * src/copy.c (punch_hole): Use it. * src/ls.c (errno_unsupported, gobble_file): Use it.
2015-04-30doc: standardize messages about the '-' stdin FILEPádraig Brady
* src/system.h (emit_stdin_note): A new function, refactoring the usage note about the '-' FILE implying stdin. * src/base64.c (usage): Use the new function to emit the note in a standard location and with standard separation. * src/cat.c (usage): Likewise. * src/csplit.c (usage): Likewise. * src/cut.c (usage): Likewise. * src/expand.c (usage): Likewise. * src/fmt.c (usage): Likewise. * src/head.c (usage): Likewise. * src/md5sum.c (usage): Likewise. * src/nl.c (usage): Likewise. * src/od.c (usage): Likewise. * src/paste.c (usage): Likewise. * src/pr.c (usage): Likewise. * src/ptx.c (usage): Likewise. * src/shred.c (usage): Likewise. * src/shuf.c (usage): Likewise. * src/sort.c (usage): Likewise. * src/sum.c (usage): Likewise. * src/tac.c (usage): Likewise. * src/tail.c (usage): Likewise. * src/tsort.c (usage): Likewise. * src/unexpand.c (usage): Likewise. * src/wc.c (usage): Likewise. * src/join.c (usage): Adjust the separation used for the message referring to FILE1 or FILE2 as stdin. * src/comm.c (usage): Add a message using the same wording (translation) as used in join. * src/split.c (usage): Reword to using FILE rather than INPUT, allowing use of emit_stdin_note(). Also remove the mention of "fixed-size" pieces as this isn't now always the case. Fixes http://pad.lv/1450179
2015-02-17maint: prefer STREQ_LEN and STRPREFIX over strncmp in all casesBernhard Voelker
* cfg.mk (sc_prohibit_strncmp): Improve the search pattern: use _sc_search_regexp to find all invocations of strncmp except when used on a macro definition line; just match the function name with an opening parenthesis. Before, the expression missed places where the comparison against 0 was in a subsequent line. * src/system.h (STRNCMP_LIT): Shorten 'literal' to 'lit' to move the whole definition of the macro into one line - thus making sc_prohibit_strncmp pass. (STRPREFIX): Add space before parenthesis. * src/du.c (main): Prefer STREQ_LEN over strncmp. * src/pinky.c (scan_entries): Likewise. * src/tac.c (tac_seekable): Likewise. * src/who.c (scan_entries): Likewise.
2015-01-01maint: update all copyright year number rangesPádraig Brady
Run "make update-copyright" and then... * tests/sample-test: Adjust to use the single most recent year. * tests/du/bind-mount-dir-cycle-v2.sh: Fix case in copyright message, so that year is updated automatically in future.
2014-12-19build: don't call OS/2 routines on all systemsKO Myung-Hun
* src/system.h: Add a missing __OS2__ ifdef guard. Also adjust spacing around () to avoid a syntax-check failure.
2014-12-18build: expand a response file and a wildcard on OS/2KO Myung-Hun
OS/2 traditional shells(cmd) do not expand a response file(@file) or a wildcard. Expand them in each utility itself. * src/system.h (initialize_main): Define on OS/2. Expand a response file and a wildcard.
2014-09-19doc: output correct --help references with --program-prefixPádraig Brady
* src/system.h (emit_ancillary_info): Take the invariant PROGRAM_NAME as a parameter, so that consistent references are made to online docs and texinfo nodes, when a --program-prefix is in place. Note the man pages don't need this fix as they're generated before the program prefix is used. * NEWS: Mention the improvements in references to online documentation.
2014-09-19doc: ensure the correct texinfo nodes are referenced in --helpPádraig Brady
* src/system.h (emit_ancillary_info): For commands that don't have a 1:1 mapping with the texinfo node names, provide a mapping to the correct node. * doc/coreutils.texi: Add some extra cross references noticed while checking this. Fixes http://bugs.debian.org/762092
2014-09-11doc: reference online info pages directly from man pagesPádraig Brady
* src/system.h (emit_ancillary_info): Add a direct reference to the corresponding online info documentation. Corresponding redirects were put in place on www.gnu.org to allow for concise links. * help2man: Adjust to add the "online help" link (and subsequent translation bugs link) to a "REPORTING BUGS" section. Also add the concise links for further information in --help to the "SEE ALSO" section, and dispense with the more verbose default for that.
2014-09-10doc: adjust reference to info nodes in man pagesPádraig Brady
old form: coreutils '$cmd invocation' new form: '(coreutils) $cmd invocation' The old form erroneously referenced the node for the 'coreutils' multi-call program. Now that problematic node name was renamed in commit v8.23-18-g72e470b, but the newer less ambiguous form also has the advantage of working with the pinfo viewer for example. Full discussion at http://bugs.gnu.org/18428 * man/local.mk: Adjust man page references to texinfo nodes. * src/system.h: Adjust --help references to texinfo nodes.
2014-07-01maint: fix const correctness warnings with security_context_tPádraig Brady
The security_context_t type was always an artificial separation from a standard char* string, and various libselinux using code assumed both were synonymous. In addition, prior to libselinux 2.3 function declarations were incorrect wrt constness of this type. Here we replace security_context_t with char*, and also provide a wrapper function to cater for the const issue on older libselinux. * src/system.h (se_const): A new function to avoid and identify the const issue on older libselinux. * src/copy.c: s/security_context_t/char */. * src/cp.c: Likewise. * src/id.c: Likewise. * src/install.c: Likewise. * src/ls.c: Likewise. * src/mkdir.c: Likewise. * src/mkfifo.c: Likewise. * src/mknod.c: Likewise. * src/runcon.c: Likewise. * src/selinux.c: Likewise. * tests/cp/no-ctx.sh: Likewise. * src/chcon.c: Likesize.
2014-05-02numfmt: improve processing throughput by 800%Pádraig Brady
The devmsg() calls that took quote_n() arguments, didn't normally output anything, but still incurred the overhead of those quote_n() calls. * src/numfmt.c (devmsg): Move the inline function with _internal_ enablement check to... * src/system.h: ...here as a variadic macro, with the enablement check at the outer level. * src/factor.c: As per numfmt.c but there is no performance change in this case. * NEWS: Mention the significant performance improvement.
2014-03-03doc: improve df --human and --si, help and man pagePádraig Brady
* src/df.c (usage): Adjust the --human and --si descriptions to not depend on each other. Also include an example that is illustrative of the rounding, suffix, width, and localized fractions. * src/system.h (emit_size_note). Adjust so that it's obvious the description is pertaining to the input SIZE argument, and not to any sizes that might be output by df for example. Fixes http://bugs.gnu.org/16922
2014-01-02maint: update all copyright year number rangesBernhard Voelker
Run "make update-copyright", but then also run this, perl -pi -e 's/2\d\d\d-//' tests/sample-test to make that one script use the single most recent year number.
2013-11-27selinux: adjust utils to run restorecon with -ZPádraig Brady
cp, mv, install, mkdir, mkfifo, mknod are adjusted so that: -Z no longer accepts an argument. -Z or --context without an argument do not warn without SELinux. --context with an argument will warn without SELinux. * src/local.mk: Reference the new selinux module where required. * src/system.h: Make the argument to --context optional. * src/mkdir.c: Likewise. Also handle the SMACK case for --context. Note we currently silently ignore -Z with SMACK. * src/mkfifo.c: Likewise. * src/mknod.c: Likewise. * src/install.c: Likewise. Note install(1) by default already set the context for target files to their system default, albeit with an older method. Use the -Z option to select between the old and new context restoration behavior, and document the differences and details for how context restoration is done in new and old methods, with a view disabling the old method entirely in future. * src/cp.c: Make the argument to --context optional. Note -Z implies --no-preserve=context. I.E. -Z overrides that aspect of -a no matter what order specified. (struct cp_options): Document the context handling options. (main): Check/adjust option combinations after all options are processed, to both simplify processing and to make handling independent of order of options on the command line. Also improve the diagnostics from a failed call to setfscreatecon(). (set_process_security_ctx): A new function, refactored to set the default context from the source file, or with the type adjusted as per the system default for the destination path. (set_file_security_ctx): A new function refactored to set the security context of an existing file, either based on the process context or the default system context for a path. (copy_internal): Use the refactored functions to simplify error handling and consistently fail or warn as needed. (copy_reg): Likewise. (copy_internal): With --preserve=context, also copy context from non regular files. Note for directories this may impact the copying of subsequent files to that directory? (copy_attr): If we're handling SELinux explicitly, then exclude to avoid the redudant copy with --preserve=context, and the problematic copy with -Z. Note SELinux attribute exclusion also now honors cp -a --no-preserve=context. Note there was a very small window over 10 years ago, where attr_copy_file was available, while attr_copy_check_permissions was not, so we don't bother adding an explicit m4 check for the latter function. * src/mv.c: Support --context, but don't allow specifying an argument. * src/chcon.c: Adjust a comment to be specific to SELinux. * src/runcon.c: Likewise. * src/copy.c: Honor the context settings to "restorecon" as appropriate. * src/copy.h: Add a new setting to select "restorecon" functionality. * tests/mkdir/selinux.sh: s/-Z/--context=/ * tests/cp/cp-a-selinux.sh: Augment this test with cases testing basic -Z functionality, and also test the various invalid option combinations and option precedence. * tests/mkdir/restorecon.sh: Add a new test for the more involved mkdir -Z handling, since the directory changing and non existent directories need to be specially handled. Also check the similar but simpler handling of -Z by mk{nod,fifo}. * tests/local.mk: Reference the new test. * doc/coreutils.texi (cp invocation): Update as per interface changes. (mv invocation): Likewise. (install invocation): Likewise. (mkfifo invocation): Likewise. (mknod invocation): Likewise. (mkdir invocation): Likewise. * NEWS: Mention the new feature and change in behavior.
2013-05-18maint: port --enable-gcc-warnings to clangPaul Eggert
* configure.ac: If clang, add -Wno-format-extra-args and -Wno-tautological-constant-out-of-range-compare. * gl/lib/rand-isaac.c (ind): * gl/lib/randread.c (readisaac): * src/ls.c (dev_ino_push, dev_ino_pop): * src/sort.c (buffer_linelim): * src/system.h (is_nul): * src/tail.c (tail_forever_inotify): Rewrite to avoid casts that clang dislikes. It's good to avoid casts anyway. * src/expr.c (integer_overflow): Declare only if it exists. (die): Remove; unused. * src/ls.c (dev_ino_push): New function, replacing ... (DEV_INO_PUSH): ... this removed macro. All uses changed. (decode_switches): Rewrite "str"+i to &str[i].
2013-02-28doc: move some info from all --help messages, onlinePádraig Brady
* src/system.h (emit_ancillary_info): Link to the bug report email addresses and general help URLs online rather than specifying directly. This give us greater scope to present better info like describing the difference between bug-coreutils@gnu.org and coreutils@gnu.org etc. * tests/misc/help-version.sh: Remove the check for bug-coreutils@gnu.org * tests/local.mk: Remove the no longer needed PACKAGE_BUGREPORT.
2013-02-20maint: cleanup up various uses of __attribute__Pádraig Brady
* src/cfg.mk (sc_prohibit-gl-attributes): Disallow the __attribute() form without trailing underscores as that is not elided where required. Also ensure we use gnulib macros rather than defining our own. * src/system.h: Remove gnulib provided macros. * src/chown-core.c: Likewise. * src/chroot.c: Likewise. * src/copy.c: Likewise. * src/csplit.c: Likewise. * src/dd.c: Likewise. * src/expr.c: Likewise. * src/extent-scan.c: Likewise. * src/factor.c: Likewise. * src/ls.c: Likewise. * src/od.c: Likewise. * src/paste.c: Likewise. * src/ptx.c: Likewise. * src/sort.c: Likewise. * src/stat.c: Likewise. * src/stty.c: Likewise. * src/system.h: Likewise. * src/tac.c: Likewise. * src/test.c: Likewise. * src/tsort.c: Likewise.
2013-02-14build: avoid link failure in devmsg() on older linkersPádraig Brady
On linkers that don't remove unused functions, there will be a reference to a missing dev_debug symbol in the devmsg() function. So for now ... * src/system.h: ... move devmsg() from here ... * src/numfmt.c: ... to here, and document future cleanup. * src/factor.c: Likewise.
2013-02-10maint: consolidate developer debug messagesPádraig Brady
Both factor and numfmt recently introduced debug messages for developers, enabled by --verbose and ---devdebug respectively. There were a few issues though: 1. They used different mechanisms to enable these messages. 2. factor used --verbose which might be needed for something else 3. They used different methods to output the messages, and numfmt used error() which added an unwanted newline 4. numfmt marked all these messages for translation and factor marked a couple. We really don't need these translated. So we fix the above issues here while renaming the enabling option for both commands to ---debug (still undocumented). * src/factor.c (verbose): Rename to dev_debug and change from int to bool as it's just a toggle flag. (long_options): Rename --verbose to ---debug. * src/system.h (devmsg): A new inline function to output a message if enabled by a global dev_debug variable in the compilation unit. * src/numfmt.c: Use devmsg() rather than error(). Also remove the translation tags from these messages. Also change debug flag to bool from int. * tests/misc/numfmt.pl: Adjust for the ---devdebug to ---debug change. * cfg.mk (sc_marked_devdiagnostics): Add a syntax check to ensure translations are not added to devmsg calls. Reported by Göran Uddeborg in http://bugs.gnu.org/13665
2013-01-23maint: define usage note about mandatory args centrallyBernhard Voelker
Each program with at least one long option which is marked as 'required_argument' and which has also a short option for that option, should print a note about mandatory arguments. Define that well-known note centrally and use it rather than literal printf/fputs, and add it where it was missing. * src/system.h (emit_mandatory_arg_note): Add new function. * src/cp.c (usage): Use it rather than literal printf/fputs. * src/csplit.c, src/cut.c, src/date.c, src/df.c, src/du.c: * src/expand.c, src/fmt.c, src/fold.c, src/head.c, src/install.c: * src/kill.c, src/ln.c, src/ls.c, src/mkdir.c, src/mkfifo.c: * src/mknod.c, src/mv.c, src/nl.c, src/od.c, src/paste.c: * src/pr.c, src/ptx.c, src/shred.c, src/shuf.c, src/sort.c: * src/split.c, src/stdbuf.c, src/tac.c, src/tail.c, src/timeout.c: * src/touch.c, src/truncate.c, src/unexpand.c, src/uniq.c: Likewise. * src/base64.c (usage): Add call of the above new function because at least one long option has a required argument. * src/basename.c, src/chcon.c, src/date.c, src/env.c: * src/nice.c, src/runcon.c, src/seq.c, src/stat.c, src/stty.c: Likewise.
2013-01-01maint: update all copyright year number rangesJim Meyering
Run "make update-copyright", but then also run this, perl -pi -e 's/2\d\d\d-//' tests/sample-test to make that one script use the single most recent year number.
2012-07-21maint: stzncpy: restrict pointer parametersJim Meyering
* src/system.h (stzncpy): Add "restrict" attribute to each pointer parameter and note in the comment that the buffers must not overlap.
2012-07-15pinky,who: fix bug in latest changeJim Meyering
* src/system.h (stzncpy): New function. * src/pinky.c (print_entry): Use stzncpy, not stpncpy. The latter does not NUL-terminate. I assumed that strncpy was the only function with such a horrible API. Today I learned that stpncpy also may not NUL-terminate its result. The bugs were introduced in commit v8.17-48-gf79263d. * src/who.c (print_user): Likewise. Thanks to Erik Auerswald for spotting my error.
2012-06-22maint: refactor common mode bits used to create filesPádraig Brady
* src/system.h (MODE_RW_UGO): The new refactored define (666). * src/mkfifo.c: Use the new define. * src/mknod.c: Likewise. * src/split.c: Likewise. * src/system.h: Likewise. * src/touch.c: Likewise. * src/truncate.c: Likewise. Suggested-by: Jim Meyering
2012-05-10maint: handle file sizes more reliablyPaul Eggert
Problem reported by Samuel Thibault in <http://bugs.gnu.org/11424>. * NEWS: Document this. * src/dd.c (skip): Handle skipping past EOF on shared or typed memory objects the same way as with regular files. (dd_copy): It's OK to truncate shared memory objects. * src/du.c (duinfo_add): Check for overflow. (print_only_size): Report overflow. (process_file): Ignore negative file sizes in the --apparent-size case. * src/od.c (skip): Fix comment about st_size. * src/split.c (main): * src/truncate.c (do_ftruncate, main): On files where st_size is not portable, fall back on using lseek with SEEK_END to determine the size. Although strictly speaking POSIX says the behavior is implementation-defined, in practice if lseek returns a nonnegative value it's a reasonable one to use for the file size. * src/system.h (usable_st_size): Symlinks have reliable st_size too. * tests/misc/truncate-dir-fail: Don't assume that getting the size of a dir is not allowed, as it's now allowed on many platforms, e.g., GNU/Linux.
2012-05-08maint: new function: usable_st_sizeJim Meyering
2012-03-22maint: ensure PATH_MAX is set correctlyPádraig Brady
This reverts part of commit v8.12-103-g54cbe6e. * src/system.h: Include gnulib's pathmax.h to honor system specific limits, and then we set PATH_MAX only if needed. Note pathmax.h no longer uses pathconf ("/", _PC_PATH_MAX). Note I didn't reinstate the comments about limits.h inclusion order, because pathmax.h includes limits.h anyway.
2012-03-06maint: refactor copy to use is_nul()Pádraig Brady
* src/dd.c: Move is_nul() from here to ... * src/system.h: ... here * src/copy.c (sparse_copy): Adjust to use the refactored is_nul()
2012-02-24doc: clarify a comment in system.hJim Meyering
* src/system.h (STRNCMP_LIT): Clarify comment. Suggested by Bruno Haible.
2012-01-27maint: use single copyright year rangeJim Meyering

Run this (twice): git grep -E -l '`.+'\' src/*.[ch] \ |xargs perl -pi -e 's/`(.+?'\'')/'\''$1/'
2012-01-07maint: update quoting of "Try `prog --help'" to "Try 'prog --help'"Jim Meyering
Automatically adjust both the source (now in only one place) and all tests that expect the resulting output via this: git grep -l 'Try.*--help' src/system.h tests \ | xargs perl -pi -e 's/Try \\?`(\S+ --help)/Try '\''$1/'
2012-01-07maint: factor out all `Try --help'-emitting statementsJim Meyering
* src/system.h (emit_try_help): New function.
2012-01-01maint: update all copyright year number rangesJim Meyering
Run "make update-copyright".
2011-11-15ls: another reword of generic size noteRuediger Meier
* src/system.h (emit_size_note): Use "unit" rather than "suffix", and move multiplication to example instead of in suffix list. See additional discussion in Bug#9939.
2011-11-11* src/system.h (emit_size_note): Reword for clarity.Paul Eggert
See discussion in Bug#9939.
2011-10-25build: do not remove definition of ENODATA, after allJim Meyering
* src/system.h (ENODATA): Restore definition. gnulib defines it only on native Windows systems, so removing our definition would have provoked build failure on systems that use it, like FreeBSD. Reported by Bruno Haible in http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/28739/focus=28795 * gnulib: Update to latest, to get new ENODATA-exempting maint.mk rule.
2011-10-24rm: update gnulib to get an fts fix for Cygwin+NWFS/NcFsd file systemsJim Meyering
* NEWS (Bug fixes): Mention it. As far as we know, this fix affects only Cygwin with NWFS or NcFsd file systems. See these: http://git.sv.gnu.org/cgit/gnulib.git/commit/?id=71f13422f3e634 http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/28739 http://cygwin.com/ml/cygwin/2011-10/msg00365.html * src/system.h (ENODATA): Remove fall-back definition, now that gnulib provides one. Caught by the sc_prohibit_always-defined_macros syntax-check rule. Also remove now-irrelevant "Don't use bcopy..." comment.
2011-10-01build: use getgr*_nomembers functions on InterixMarkus Duft
Interix provides faster replacements for getgr{gid,nam,ent} where group member information is not fetched from domain controllers. This makes 'id' usable on domain controlled interix boxes. * m4/jm-macros.m4: Check for _nomembers functions. * src/system.h: Redefine function to _nomembers when available.
