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.
2015-10-27all: quote string arguments in error messagesPádraig Brady
These strings are often file names or other user specified parameters, which can give confusing errors in the presence of unexpected characters for example. * cfg.mk (sc_error_quotes): A new syntax check rule. * src/*.c: Wrap error() string arguments with quote(). * tests/: Adjust accordingly. * NEWS: Mention the improvement.
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.
2014-09-19doc: 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

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.

2009-10-26tests: clean up tests of env -- handlingEric Blake
The comment in env.c about -- handling has not matched the behavior in the code since the initial commit back in 1992. * src/env.c: Fix bogus comment. * tests/misc/env: Further tweaks, avoiding PATH problems inherent in testing -i, and testing program name containing =. * doc/coreutils.texi (env invocation): Mention that intermediate program is needed to invoke program with name containing =.
2009-10-26env: reject bogus -u argumentsEric Blake
* src/env.c (main): Use unsetenv rather than putenv to remove items from environ, and check for failure. * bootstrap.conf (gnulib_modules): Add unsetenv. * tests/misc/env: Test this. * NEWS: Document it.

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
