2012-01-01maint: update all copyright year number rangesJim Meyering
Run "make update-copyright".
2011-11-29build: simplify warnings based on last gnulib updateEric Blake
We no longer need to exclude this warning. * configure.ac (WARN_CFLAGS): Gnulib dropped -Wunsuffixed-float-constants, as non-portable.
2011-11-28build: enable -Wsuggest-attribute=pure|const in lib/,...Jim Meyering
but not in gnulib-tests/. * configure.ac (GNULIB_WARN_CFLAGS): Do not exclude -Wsuggest-attribute=pure|const, thus enabling these two warning options in lib/, since gnulib now toes the line. Continue to disable them in gnulib-tests/, since some programs there trigger these suggestions and are not worth fixing.
2011-11-27maint: update comment gcc-4.6.2 still botches -Wsuggest-attribute=pureJim Meyering
* configure.ac: Update the comment on which gcc versions still must not use -Wsuggest-attribute=pure option: still required on post- Fedora 16 rawhide's 4.6.2 20111027.
2011-11-23build: --enable-gcc-warnings: disable some new warningsJim Meyering
* configure.ac: Disable some new warning options pulled in via an update to gnulib's manywarnings module: -Wformat-nonliteral, -Wunsuffixed-float-constants, -Wdouble-promotion.
2011-10-01build: stop distributing gzip'd releases; xz is enoughJim Meyering
* configure.ac (AM_INIT_AUTOMAKE): Add no-dist-gzip. * NEWS (Build-related): Mention that we're dropping .tar.gz.
2011-09-12build: avoid unwarranted failure w/gcc-4.6.1 and --enable-gcc-warningsJim Meyering
* configure.ac (gl_GCC_VERSION_IFELSE): Define new macro. (WERROR_CFLAGS): With --enable-gcc-warnings, use it to add -Wsuggest-attribute=pure only with gcc 4.7 or newer.
2011-08-11bootstrap: use latest gnulib bootstrap, gettextPaul Eggert
* bootstrap: Sync from gnulib. This removes an obsolescent gettext.m4 patch, along with some other changes that do not seem to affect coreutils. * bootstrap.conf (gnulib_modules): Use gettext, not gettext-h. Current gnulib gettext seems to work without needing special hacking. * configure.ac (AM_GNU_GETTEXT_VERSION): Now 0.18.1, not 0.17. * gnulib: Update to latest.
2011-07-02maint: use "const" and "pure" function attributes where possibleJim Meyering
* configure.ac (WARN_CFLAGS): Add -Wsuggest-attribute=const, -Wsuggest-attribute=pure and -Wsuggest-attribute=noreturn. (GNULIB_WARN_CFLAGS): But do not add them here... yet. * src/chown-core.h (chopt_free, uid_to_name): Add function attribute(s). * src/copy.c (is_ancestor, valid_options): Likewise. * src/copy.h (chown_failure_ok): Likewise. * src/dd.c (operand_matches, operand_is): Likewise. * src/df.c (selected_fstype, excluded_fstype): Likewise. * src/expr.c (null looks_like_integer): Likewise. * src/md5sum.c (hex_digits): Likewise. * src/od.c (get_lcm): Likewise. * src/pathchk.c (component_start, component_len): Likewise. * src/pinky.c (count_ampersands): Likewise. * src/pr.c (cols_ready_to_print): Likewise. * src/ptx.c (search_table): Likewise. * src/sort.c (find_unit_order): Likewise. * src/stty.c (mode_type_flag, string_to_baud, baud_to_value): Likewise. * src/system.h (gcd, lcm): Likewise. * src/tr.c (is_char_class_member, look_up_char_class): Likewise.

2011-06-18maint: fix typo in comment in configure.acStefano Lattarini
* configure.ac ($MAN): Fix typo in explanatory comment.
2011-06-04build: require at least 2-year old autoconf-2.64 (was 2.62)Jim Meyering
* configure.ac: Require autoconf-2.64, which is nearly two years old. * src/system.h (emit_ancillary_info): Use PACKAGE_URL, now that we require autoconf-2.64.
2011-05-26build: --enable-gcc-warnings: enable -Wstrict-overflow in src/Jim Meyering
* configure.ac (WARN_CFLAGS): Don't turn off -Wstrict-overflow. (GNULIB_WARN_CFLAGS): Remove -Wstrict-overflow from the list of warning options used in lib/. Normally I find that -Wstrict-overflow produces too many false positives, but considering that it warns of the bug reported in http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33498, I now think it is worthwhile. The lesser of two evils. Thanks to Daniel Veillard for showing me the gcc bug report.
2011-05-08maint: remove -Wmissing-field-initializers workaroundsPádraig Brady
* configure.ac: Rather than disabling -Wmissing-field-initializers, use the fact that gnulib now disables it automatically when required (on versions of GCC older than 4.7). * src/system.h: Remove the no longer needed DECLARE_ZEROED_AGGREGATE. * src/ls.c: Likewise. * src/pathchk.c: Likewise. * src/shred.c: Likewise. * src/stty.c: Likewise. * src/wc.c: Likewise.
2011-03-16maint: stop using .x-sc_* files to list syntax-check exemptionsJim Meyering
Instead, use the brand new mechanism with which you merely use a variable (derived from the rule name) defined in cfg.mk to an ERE matching the exempted file names. * gnulib: Update to latest, to get maint.mk that implements this. * Makefile.am (syntax_check_exceptions): Remove variable. (EXTRA_DIST): Remove use of the variable. * cfg.mk (sc_x_sc_dist_check): Remove rule, no longer useful. (exclude_file_name_regexp--sc_space_tab): Define variable.

2010-12-30maint: allow gettext 0.17 againEric Blake
Commit 041c9c47 traded the 'gettext' module for the lighter 'gettext-h' module, so as to not require the latest gettext release (we only need the latest release if we ship gettext as a dependent library, but coreutils has long preferred to use it as an external library). But that commit overlooked two places necessary to allow the use of gettext 0.17. This does not force you to downgrade (using gettext 0.18.1.1 is still just fine), nor does it affect tarballs (once a tarball is built with a given gettext version, it can be built on other machines regardless of what gettext version is present). * bootstrap.conf (buildreq): Relax prerequisite. * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
2010-11-16build: enable the -Wpointer-sign gcc warningPádraig Brady
... when configured with the --enable-gcc-warnings option. This follows on from commit 34ef0a01, 2010-10-14, "sort: fix unportable cast of unsigned char * -> char *" * configure.ac: -Wall implicitly enables this warning so remove the explicit disabling.
2010-10-13build: prepare to enable -Werror also for gnulib-tests/Jim Meyering
* configure.ac (GNULIB_WARN_CFLAGS): Define new variable, for use in gnulib-tests. * gnulib-tests/Makefile.am: Disable specific -W___ options, but only for a few specific offending tests: (test_xvasprintf_CFLAGS): Define. (test_lock_CFLAGS, test_tls_CFLAGS): Define.
2010-07-22build: support fully excluding stdbuf from the buildMike Frysinger
* configure.ac (optional_pkglib_progs): Only update after the main programs have been selected, so that libstdbuf.so can be excluded if stdbuf also is.
2010-05-11build: record the gettext-0.18 requirement also in configure.acJim Meyering
* configure.ac: Require gettext-0.18 here, too.
2010-01-06build: require newer versions of automake and autoconfJim Meyering
* configure.ac: Require autoconf-2.62 and automake-1.11.1 or newer. * bootstrap.conf (buildreq): Require automake-1.11.1 or newer, to ensure people use a version with the fix for CVE-2009-4029. Note that the coreutils-8.2 tarball included a fixed Makefile.in. Require autoconf-2.62, per automake.
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

2009-11-13build: correct gettext configure-time supportJim Meyering
* configure.ac: Use AM_GNU_GETTEXT([external], [need-ngettext]), rather than AM_GNU_GETTEXT([external], [need-formatstring-macros]). Reported by Martin Jacobs in http://thread.gmane.org/gmane.comp.parsers.bison.bugs/3181 * THANKS: Add his name.
2009-10-29build (--enable-gcc-warnings): enable gcc's -Werror also in lib/Jim Meyering
* 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.
2009-10-22maint: turn on compiler warnings for gnulib testsEric Blake
* gnulib-tests/Makefile.am (AM_CFLAGS): Add WARN_CFLAGS. * configure.ac (enable-gcc-warnings): Also use -funit-at-a-time, to silence gcc 4.3.4 -Wdisabled-optimization. * .gitignore: Ignore some more files.
2009-10-10build: build uname(1) unconditionallyJim Meyering
Before, on a system without the uname function, the build system would detect that and not build/install a uname program. Now that gnulib guarantees a uname function, ... * configure.ac: Don't check for the uname function. * src/Makefile.am (build_if_possible__progs): Move uname... (EXTRA_PROGRAMS): ...to this list.
2009-09-11build: placate gcc's new -Wskip-jump-initJim Meyering

Transformed via this shell code: t=$'\t' git ls-files \ | grep -vE '(^|/)((GNU)?[Mm]akefile|ChangeLog)|\.(am|mk)$' \ | grep -vE 'tests/pr/|help2man' \ | xargs grep -lE "^ *$t" \ | xargs perl -MText::Tabs -ni -le \ '$m=/^( *\t[ \t]*)(.*)/; print $m ? expand($1) . $2 : $_'
2009-08-17build: suppress warnings due to gcc's new -Wjump-misses-initJim Meyering
* configure.ac: Ignore -Wjump-misses-init violations in remove.c.
2009-07-09build: avoid build warn/failure due to -Wstack-protectorJim Meyering
* configure.ac: Do not enable -Wstack-protector. Otherwise, at least df.c would provoke a warning.
2009-06-17stdbuf: A new program to run a command with modified stdio bufferingPádraig Brady
* AUTHORS: Register as the author. * NEWS: Mention this change. * README: Add stdbuf command to list. * configure.ac: Only enable on ELF systems with GCC. * cfg.mk (sc_system_h_headers): Use VC_LIST_EXCEPT rather than VC_LIST, so we can add an exception, if needed. * .x-sc_system_h_headers: New file. Exempt libstdbuf.c. * Makefile.am (syntax_check_exceptions): Add .x-sc_system_h_headers. * doc/coreutils.texi (stdbuf invocation): Add stdbuf info. * man/.gitignore: Ignore generated manpage. * src/.gitignore: Ignore stdbuf and libstdbuf.so binaries. * man/Makefile.am (stdbuf.1): Add dependency. * man/stdbuf.x: New file with example usage. * po/POTFILES.in: Reference new command and shared library sources. * src/Makefile.am (build_if_possible__progs): Add stdbuf and libstdbuf, (pkglib_PROGRAMS): Reference optional shared lib, (libstdbuf_so_LDADD): Ensure we don't link with non PIC libcoreutils.a.

2009-05-18build: require automake-1.11Jim Meyering
* bootstrap.conf (buildreq): Require automake-1.11, not 1.10b, for our use of AM_SILENT_RULES. * configure.ac (AM_INIT_AUTOMAKE): Likewise.
2009-05-17build: avoid new warnings from gcc 4.5.0 20090517Jim Meyering
* configure.ac: Add an explicit -Wno-logical-op, now that not listing -Wlogical-op is insufficient.
2009-05-17build: turn off -Wlong-longJim Meyering
* configure.ac: With --enable-gcc-warnings, -Wlong-long would cause compilation failure due to inclusion of lib/gethrxtime.h. Initialize "nw".
2009-04-23build: make --enable-silent-rules the defaultJim Meyering
* configure.ac (AM_INIT_AUTOMAKE): Remove silent-rules. Instead,... (AM_SILENT_RULES): Use this, with it's undocumented [yes] argument. Those who want verbose build output may configure with --disable-silent-rules or use "make V=1".
