2016-11-14all: reduce usage of proper_name_utf8()Pádraig Brady
This reduces a standard coreutils install size by about 160K. * src/cat.c: Change to proper_name() which removes about 18K text. * src/cp.c: Likewise. * src/df.c: Likewise. * src/du.c: Likewise. * src/getlimits.c: Likewise. * src/realpath.c: Likewise. * src/split.c: Likewise. * src/stdbuf.c: Likewise. * src/timeout.c: Likewise. * src/truncate.c: Likewise. * src/local.mk: Remove -llibiconv from the above programs. * cfg.mk (sc_check-AUTHORS): Adjust to use factor(1). * AUTHORS: Adjust to use ASCII to satisfy sc_check-AUTHORS.
2016-10-16all: use die() rather than error(EXIT_FAILURE)Pádraig Brady
die() has the advantage of being apparent to the compiler that it doesn't return, which will avoid warnings in some cases, and possibly generate better code. * cfg.mk (sc_die_EXIT_FAILURE): A new syntax check rule to catch any new uses of error (CONSTANT, ...);
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.

* NEWS: Use a standard version specification. * doc/coreutils.texi: Fix incorrect grammar. * src/df.c: Update a stale comment. * src/copy.c: Fix incorrect spellings. * src/factor.c: Likewise. * src/ls.c: Likewise. * src/pr.c: Likewise. * src/relpath.c: Likewise. * src/shred.c: Likewise. * src/sort.c: Likewise. * src/split.c: Likewise. * src/stdbuf.c: Likewise. * tests/misc/seq-precision.sh: Likewise.
2015-06-29maint: stdbuf.c: avoid the OS X putenv functionJim Meyering
* bootstrap.conf (gnulib_modules): Add setenv, to make this module dependency explicit; setenv is also used by split. * src/stdbuf.c (set_LD_PRELOAD) [__APPLE__]: Use the OS X setenv function, rather than putenv, per that documentation: https://developer.apple.com/\ library/mac/documentation/Darwin/Reference/ManPages/man3/putenv.3.html
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.
2014-12-19diagnose too-large numbers betterPádraig Brady
Following on from commit v8.23-82-gaddae94, consistently diagnose numbers that are too large, so as to distinguish from other errors, and make the limits obvious. * gl/modules/xdectoint: A new module implementing xdecto[iu]max(), which handles the common case of parsing a bounded integer and exiting with a diagnostic on error. * gl/lib/xdectoimax.c: The signed variant. * gl/lib/xdectoint.c: The parameterized implementation. * gl/lib/xdectoint.h: The interface. * gl/lib/xdectoumax.c: The unsigned variant. * bootstrap.conf: Reference the new module. * cfg.mk (exclude_file_name_regexp--sc_require_config_h_first): Exclude the parameterized templates. * src/csplit.c: Output EOVERFLOW or ERANGE errors if appropriate. * src/fmt.c: Likewise. * src/fold.c: Likewise. * src/head.c: Likewise. * src/ls.c: Likewise. * src/nl.c: Likewise. * src/nproc.c: Likewise. * src/shred.c: Likewise. * src/shuf.c: Likewise. * src/stdbuf.c: Likewise. * src/stty.c: Likewise. * src/tail.c: Likewise. * src/truncate.c: Likewise. * src/split.c: Likewise. * src/pr.c: Likewise. * tests/pr/pr-tests.pl: Adjust to avoid matching errno diagnostic. * tests/fmt/base.pl: Likewise. * tests/split/l-chunk.sh: Likewise. * tests/misc/shred-negative.sh: Likewise. * tests/misc/tail.pl: Likewise. Also remove the redundant existing ERR_SUBST from test err-6. * tests/ls/hex-option.sh: Check HEX/OCT options. * tests/misc/shred-size.sh: Likewise. * tests/misc/stty-row-col.sh: Likewise.
2014-09-23doc: fix use of "e.g." in stdbuf help messageMichal Nazarewicz
"E.g." stands for latin "exempli gratia" which is typically read as "for example". "E.g." does not stand for the word "example". As such, "for e.g." might be read as "for for example". Fix this usage by simply replacing "e.g." with "example".
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.
2014-09-08maint: prefer 'return status;' to 'exit (status);' in 'main'Paul Eggert
* build-aux/gen-single-binary.sh: Don't use ATTRIBUTE_NORETURN for main functions. * src/base64.c, src/basename.c, src/cat.c, src/chcon.c, src/chgrp.c: * src/chmod.c, src/chown.c, src/chroot.c, src/cksum.c, src/comm.c: * src/cp.c, src/csplit.c, src/cut.c, src/date.c, src/dd.c, src/df.c: * src/dircolors.c, src/dirname.c, src/du.c, src/echo.c, src/env.c: * src/expand.c, src/expr.c, src/factor.c, src/fmt.c, src/fold.c: * src/getlimits.c, src/groups.c, src/head.c, src/hostid.c: * src/hostname.c, src/id.c, src/install.c, src/join.c, src/kill.c: * src/link.c, src/ln.c, src/logname.c, src/ls.c, src/make-prime-list.c: * src/md5sum.c, src/mkdir.c, src/mkfifo.c, src/mknod.c, src/mktemp.c: * src/mv.c, src/nice.c, src/nl.c, src/nohup.c, src/nproc.c: * src/numfmt.c, src/od.c, src/paste.c, src/pathchk.c, src/pinky.c: * src/pr.c, src/printenv.c, src/printf.c, src/ptx.c, src/pwd.c: * src/readlink.c, src/realpath.c, src/rm.c, src/rmdir.c, src/runcon.c: * src/seq.c, src/shred.c, src/shuf.c, src/sleep.c, src/sort.c: * src/split.c, src/stat.c, src/stdbuf.c, src/stty.c, src/sum.c: * src/sync.c, src/tac.c, src/tail.c, src/tee.c, src/timeout.c: * src/touch.c, src/tr.c, src/true.c, src/truncate.c, src/tsort.c: * src/tty.c, src/uname.c, src/unexpand.c, src/uniq.c, src/unlink.c: * src/uptime.c, src/users.c, src/wc.c, src/who.c, src/whoami.c: In 'main' functions, Prefer 'return status;' to 'exit (status);'. * src/coreutils-arch.c (_single_binary_main_uname) (_single_binary_main_arch): * src/coreutils-dir.c, src/coreutils-vdir.c (_single_binary_main_ls) (_single_binary_main_dir, _single_binary_main_vdir): Omit ATTRIBUTE_NORETURN. Return a value. * src/coreutils.c (SINGLE_BINARY_PROGRAM): Omit ATTRIBUTE_NORETURN. (launch_program): Now static. * src/dd.c (finish_up): New function. (quit, main): Use it. * src/getlimits.c (main): Return a proper exit status. * src/test.c (test_main_return): New macro. (main): Use it. * src/logname.c, src/nohup.c, src/whoami.c: Use 'error' to simplify exit status in 'main' function. * src/yes.c (main): Use 'return' rather than 'error' to exit, so that GCC doesn't suggest ATTRIBUTE_NORETURN.
2014-05-26stdbuf: support OS XPádraig Brady
* src/stdbuf.c (set_LD_PRELOAD): Adjust to use Mac OS X specific environment variables on __APPLE__ platforms. Fixes http://bugs.gnu.org/17590
2014-05-21stdbuf: support compilers other than __GNUC__Pádraig Brady
__SUNPRO_C >= 0x590 /*12.0*/ supports __attribute((constructor)) required by stdbuf, so use a more direct check for this. Note ensure that --libexecdir is set to the appropriate install location for libstdbuf.so so that stdbuf works when installed on the system like it does when running tests in the build directory. * configure.ac (stdbuf_supported): Use a test prog to determine support. * src/libstdbuf.c (stdbuf): Define appropriately for non GCC compilers, and provide early feedback (compilation warning) if trying to compile libstdbuf without the necessary support. * src/stdbuf.c (set_LD_PRELOAD): Add a note on having stdbuf look for libstdbuf.so in the default lib search path. * cfg.mk (sc_prohibit-gl-attributes): Adjust so we can exclude libstdbuf.so from prohibiting '__attribute', since we want this form to avoid silently eliding this required attribute on non GCC. Reported and tested by Rich Burridge.
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.
2013-06-22stdbuf: make it mandatory to specify a buffering optionPádraig Brady
This is consistent with the documented interface and avoids any ambiguity in a user thinking that stdbuf without options might reset to a "standard" buffering setup. * src/stdbuf.c (set_libstdbuf_options): Indicate with the return value whether any env variables were actually set. (main): Fail unless some env variables were set. * tests/misc/stdbuf.sh: Ensure this constraint is enforced. * NEWS: Mention the small change in behavior.
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.
2012-01-09maint: src/*.c: change remaining quotes (without embedded spaces)Jim Meyering
Run this (twice): git grep -E -l '`[^ ]+'\' src/*.c \ |xargs perl -pi -e 's/`([^ ]+'\'')/'\''$1/'
2012-01-09maint: convert `...' to '...' in --help outputJim Meyering
All affected lines end with \ or \n\, so run this command until it produces no new changes (4 times): git grep -E -l '`[^ ]+'\''.*\\' src \ |xargs perl -pi -e 's/`([^ ]+'\''.*\\)/'\''$1/'
2012-01-07maint: use new emit_try_help in place of equivalent fprintfJim Meyering
Run this command: perl -0777 -pi -e \ 's/fprintf \(stderr, _\("Try `%s --help.*\n.*;/emit_try_help ();/m'\ src/*.c
2012-01-01maint: update all copyright year number rangesJim Meyering
Run "make update-copyright".
2011-09-01stdbuf: fix helper lib identification on some platformsPádraig Brady
* src/stdbuf.c (main): Pass the path of `stdbuf` rather than the command it's running to the search function. This is significant on platforms without /proc/self/exe Reported by Bruno Haible
2011-06-19stdbuf: fix automake variable name to work with cutting edge automakeJim Meyering
* src/Makefile.am (pkglibexec_PROGRAMS): Rename from pkglib_PROGRAMS. The latter is invalid. Without this change, automake v1.11-373-g9ca6326 and newer (on master) would fail with this: `pkglibdir' is not a legitimate directory for `PROGRAMS' This changes the default installation directory of libstdbuf.so from $prefix/lib/coreutils/ to $prefix/libexec/coreutils/ * src/stdbuf.c (set_LD_PRELOAD): Search in PKGLIBEXECDIR, not PKGLIBDIR, since that's where we install libstdbuf.so. Do not search in "", the system default search path.
2011-06-09maint: remove unneeded includesPádraig Brady
Remove unneeded includes as reported by: http://code.google.com/p/include-what-you-use/ * src/cp-hash.c: Remove unused include. * src/dd.c: Likewise. * src/du.c: Likewise. * src/head.c: Likewise. * src/kill.c: Likewise. * src/ls.c: Likewise. * src/stdbuf.c: Likewise. * src/timeout.c: Likewise. * src/truncate.c: Likewise.
2011-05-29maint: placate -Wsign-compare when it's non-invasiveJim Meyering
* src/stdbuf.c: Declare loop index to be unsigned.
2011-02-18stdbuf: avoid even the appearance of a possible use-after-freeJim Meyering
There was an execution path by which "libstdbuf" could be used after being freed, but that would happen only if there were no libstdbuf.so alongside the stdbuf program and there had been an installation error leading to absence of the file, PKGLIBDIR/libstdbuf.so. * src/stdbuf.c (set_LD_PRELOAD): Rearrange loop to make it perfectly clear that there is no possibility of use-after-free. Steve Grubb reported this possible use-after-free of "libstdbuf".
2011-01-01maint: update all copyright year number rangesJim Meyering
Run "make update-copyright".
2010-02-15doc: fix inconsistent capitalization in --help outputPádraig Brady
* src/base64.c (usage): Don't capitalize the first character in an --option description. * src/stdbuf.c (usage): Likewise. * src/truncate.c (usage): Likewise. * cfg.mk (sc_option_desc_uppercase): A new syntax check to stop this happening in future. * man/Makefile.am (sc_option_desc_uppercase): Ensure all man pages are generated, then search for erroneous uppercase chars. * src/Makefile.am (all_programs): Ensure all commands are built so that all man pages can be generated.
2010-01-01maint: update all FSF copyright year lists to include 2010Jim Meyering
Use this command: git ls-files | grep -v COPYING \ | xargs env UPDATE_COPYRIGHT_USE_INTERVALS=1 \ build-aux/update-copyright
2009-10-26maint: let gnulib provide environEric Blake
* bootstrap.conf (gnulib_modules): Add environ. * src/env.c (environ): Delete declaration. * src/printenv.c (environ): Likewise. * src/stdbuf.c (environ): Likewise. * src/su.c (environ): Likewise.
2009-10-08maint: move timeout exit statusesEric Blake
* src/timeout.c (EXIT_TIMEDOUT, EXIT_CANCELED): Remove as macros... * src/system.h (EXIT_TIMEDOUT, EXIT_CANCELED): ...and provide as enum values instead. * src/stdbuf.c (EXIT_CANCELED): Delete.
2009-10-08stdbuf: improve path searchEric Blake
* src/stdbuf.c (set_program_path): Use gnulib methods for better file name handling. * bootstrap.conf (gnulib_modules): Add xreadlink.
2009-09-21doc: mention the texinfo documentation in --helpPádraig Brady
* src/system.h: Rename emit_bug_reporting_address() to emit_ancillary_info() and update it to not print the translation project address in en_* locales, and _do_ print it in the 'C' (and other) locales so that it's included in the default man page. Also mention how to invoke the texinfo documentation for each command. Also move the "hard-locale.h" include to the 8 files that now use it. * man/help2man: Strip the newly added texinfo reference from the --help output as a more verbose version is already added by help2man. Suggestion from C de-Avillez
2009-08-31maint: revert my stdbuf change: the result didn't even compileJim Meyering
This reverts commit c1e158489d88bad418d52ceadf37af0b6f5b2112.
2009-08-30maint: stdbuf: move a declaration; no-semantic-changeJim Meyering
* src/stdbuf.c (set_program_path): Move a declaration down into the scope where it's used.
