2012-09-10maint: allow per-directory CFLAGS settings with non-recursive makeJim Meyering
* src/local.mk (AM_CFLAGS): Don't use $(WARN_CFLAGS) here. * cfg.mk (src_CFLAGS, lib_CFLAGS, gnulib-tests_CFLAGS): Define here instead. (AM_CFLAGS): Augment using the above. * configure.ac: Note that the configure-time option, --enable-gcc-warnings now functions only when using GNU make. Well, currently it does still work in gnulib-tests, but that should soon be fixed. Improved-by: Stefano Lattarini
2012-09-10maint: gen-lists-of-programs.sh: improve commentsJim Meyering
* build-aux/gen-lists-of-programs.sh: Improve comments.
2012-09-10build: do not require help2man at build-from-tarball timeJim Meyering
But do retain full dependencies when building from a git clone. We do this by converting the full dependency (of the .1 file on the binary we run with --help) into a dependency on the .c file. * Makefile.am (do-not-require-help2man): New rule. (dist-hook): depend on it.
2012-09-10build: fix a minor man-page generation dependency errorJim Meyering
* man/local.mk (man/dir.1): Depend on src/dir, not src/ls.
2012-09-10maint: move the last coreutils-specific files from lib/ to gl/Jim Meyering
Convert the few remaining coreutils-specific files in lib/ to gnulib-style modules under gl/, removing their corresponding .m4 files, since the information recorded in those files is better stored in module-description file in gl/modules/. * bootstrap.conf (gnulib_modules): Add new modules: fd-reopen, buffer-lcm, xfts, strnumcmp. * gl/lib/buffer-lcm.c: Renamed from the file in lib/. * gl/lib/buffer-lcm.h: Likewise. * gl/lib/fd-reopen.c: Likewise. * gl/lib/fd-reopen.h: Likewise. * gl/lib/strintcmp.c: Likewise. * gl/lib/strnumcmp-in.h: Likewise. * gl/lib/strnumcmp.c: Likewise. * gl/lib/strnumcmp.h: Likewise. * gl/lib/xfts.c: Likewise. * gl/lib/xfts.h: Likewise. * gl/modules/buffer-lcm: New module-description file. * gl/modules/fd-reopen: Likewise. * gl/modules/strnumcmp: Likewise. * gl/modules/xfts: Likewise. * m4/fd-reopen.m4: Remove, no longer needed. * m4/strnumcmp.m4: Likewise. * m4/xfts.m4: Likewise. * m4/prereq.m4: Do not AC_REQUIRE the m4 functions from our just-removed m4/*.m4 files.
2012-09-10maint: move gl/m4/root-dev-ino.m4 contents into its module definitionJim Meyering
We can get the same effect using the modules file. * gl/m4/root-dev-ino.m4: Remove file. * gl/modules/root-dev-ino (Depends-on): Add lstat. (Files): Remove m4/root-dev-ino.m4. (Makefile.am) [lib_SOURCES]: Add root-dev-ino.c and root-dev-ino.h. (configure.ac): Remove reference to gl_ROOT_DEV_INO.
2012-09-08maint: adjust ChangeLog to correct AuthorJim Meyering
* build-aux/git-log-fix: Add an entry to correct the Author: of v8.19-111-g51a4b04. It should be Ondrej Oprala, not me.
2012-09-07factor: NEWS and testsJim Meyering
* NEWS (Bug fixes): Mention it. * tests/misc/factor.pl: Add five of Torbjörn's tests.
2012-09-07factor: don't ever declare composites to be primeTorbjörn Granlund
The multiple-precision factoring code (with HAVE_GMP) was copied from a now-obsolete version of GMP that did not pass proper arguments to the mpz_probab_prime_p function. It makes that code perform no more than 3 Miller-Rabin tests only, which is not sufficient. A Miller-Rabin test will detect composites with at least a probability of 3/4. For a uniform random composite, the probability will actually be much higher. Or put another way, of the N-3 possible Miller-Rabin tests for checking the composite N, there is no number N for which more than (N-3)/4 of the tests will fail to detect the number as a composite. For most numbers N the number of "false witnesses" will be much, much lower. Problem numbers are of the form N=pq, p,q prime and (p-1)/(q-1) = s, where s is a small integer. (There are other problem forms too, involving 3 or more prime factors.) When s = 2, we get the 3/4 factor. It is easy to find numbers of that form that cause coreutils' factor to fail: 465658903 2242724851 6635692801 17709149503 17754345703 20889169003 42743470771 54890944111 72047131003 85862644003 98275842811 114654168091 117225546301 ... There are 9008992 composites of the form with s=2 below 2^64. With 3 Miller-Rabin tests, one would expect about 9008992/64 = 140766 to be invalidly recognized as primes in that range. * src/factor.c (MR_REPS): Define to 25. (factor_using_pollard_rho): Use MR_REPS, not 3. (print_factors_multi): Likewise. * THANKS.in: Remove my name, now that it will be automatically included in the generated THANKS file.
2012-09-07tests: improve checks for setuidgid-using root-only testsJim Meyering
* init.cfg (setuidgid_has_perm_): New function. (require_root_): Use it. Improved-by: Bernhard Voelker * NEWS (Build-related): Mention the improvement.
2012-09-06build: default to --enable-gcc-warnings for git treeEric Blake
Anyone developing on coreutils can be assumed to have a new enough environment, such that enabling gcc warnings by default will be useful. Tarballs still default to no warnings, and the defaults can still be overridden with --disable-gcc-warnings. * configure.ac (gl_gcc_warnings): Set default based on environment. Suggested by Bernhard Voelker.
2012-09-06nproc: disallow non option command line parametersPádraig Brady
* src/nproc.c (main): Error if any non option parameters. * NEWS: Mention the change in behavior.
2012-09-06tail,stat: add support for VZFSJim Meyering
* src/stat.c (human_fstype): Add a case: vzfs, 0x565A4653 (local). Reported by Jens Rosenboom in http://bugs.gnu.org/12356 * NEWS (Improvement): Mention it.
2012-09-05rm: be more careful when using a replacement errno valueJim Meyering
* src/remove.c (excise): Tighten the test for when we defer to an old errno value: instead of relying solely on an FTS_DNR (unreadable directory) failure, also test current and replacement errno values. This change would also have solved the problem addressed by commit v8.19-106-g57dd067. For more info, see http://bugs.gnu.org/12339#113
2012-09-05rm: avoid bogus diagnostic for a slash-decorated symlink-to-dirJim Meyering
These commands would evoke an invalid diagnostic: $ mkdir d && ln -s d s && env rm -r s/ rm: cannot remove 's': Too many levels of symbolic links remove.c was stripping trailing slashes from "s/" before passing the name to "rm". But a trailing slash may change the semantics, and thus should not be stripped. * src/remove.c (rm_fts): Do not strip trailing slashes. * tests/rm/v-slash.sh: Adapt to new expected output. * gnulib: Update to latest, for an improved fts.c that merely normalizes trailing slashes. Reported by Paul Eggert in discussion of http://bugs.gnu.org/12339
2012-09-05tests: depend on the programs we're testingJim Meyering
* tests/local.mk ($(TEST_LOGS)): Depend on $(PROGRAMS), so that tests are rerun when any program is rebuilt. Technically, we could specify precisely which few programs are dependents of each test, but that can come later, if deemed worth the trouble and maintenance burden. Also, there is the issue of the primary program(s) being tested (i.e., those itemized via print_ver_) versus those that are tested incidentally: for example, nearly every test exercises "rm" when its clean-up code removes files.
2012-09-05maint: fix a spurious syntax-check failureStefano Lattarini
* cfg.mk (exclude_file_name_regexp--sc_file_system): Exempt 'init.cfg', not 'tests/init.cfg'.
2012-09-05tests: more resilient about tainted absolute srcdir pathStefano Lattarini
* tests/init.cfg (stty_reversible_init_): Quote '$abs_top_srcdir' properly. (fiemap_capable_): Quote '$abs_srcdir' properly. (require_dirent_d_type_): Likewise.
2012-09-05maint: fix syntax checks 'sc_root_tests'Stefano Lattarini
* cfg.mk: Don't work by trying to parse the (now gone) file 'tests/Makefile.am'; rather, use the contents of the make variable, $(all_root_tests), introduced few commits ago. Fix a few unrelated cosmetic issues while at it.
2012-09-05maint: avoid a spurious syntax-check errorStefano Lattarini
* cfg.mk (exclude_file_name_regexp--sc_prohibit_test_backticks): Exempt 'tests/local.mk' rather than 'tests/Makefile.am'.
2012-09-05maint: vc_exe_in_TESTS should actually be a syntax checkStefano Lattarini
Because it requires the presence of the '.git' directory, that is, can be run only for maintainers working from checked-out sources. * tests/local.mk (vc_exe_in_TESTS): Rename and move ... * cfg.mk (sc_tests_list_consistency): ... here, with minor adjustments.
2012-09-05build: remove two now-useless convenience targetsStefano Lattarini
* src/local.mk (built_programs.list, all_programs.list): These.
2012-09-05tests: put test-suite.log back in 'tests/'Stefano Lattarini
* tests/local.mk (TEST_SUITE_LOGS): Define to 'tests/test-suite.log'.
2012-09-05build: don't use recursive make for tests/ subdirectoryStefano Lattarini
* Makefile.am (SUBDIRS): Remove 'tests'. (include): The '$(top_srcdir)/tests/local.mk' file. (check-root): Remove this convenience target, it's no longer needed now that the "real" check-root target once in 'tests/Makefile' will land in the top-level makefile. * configure.ac (AC_CONFIG_FILES): Remove 'tests/Makefile'. * tests/Makefile.am: Rename ... * tests/local.mk: ... like this, with a lot of adjustments. * tests/init.cfg: Move ... * init.cfg: ... here. This is necessary, for a limitation of the gnulib-provided 'tests/init.sh', which unconditionally look for 'init.cfg' in the $(srcdir) directory. * tests/*/*.sh: Adjust: expect init.sh to be in '$srcdir/tests', not in '$srcdir', and extend $PATH with './src', not with '../src'. * tests/Coreutils.pm: Adjust similarly. * tests/pr/pr-tests.pl ($pfx): Likewise.
2012-09-05maint: list of names of built programs available in the MakefilesStefano Lattarini
This is just a preparatory refactoring in view of future changes. * configure.ac (AC_SUBST): New 'built_programs'. * tests/Makefile.am (AM_TESTS_ENVIRONMENT): Simply define the exported variable 'built_programs' to the expansion of the '$(built_programs)' AC_SUBST'd make variable. (.built-programs): Remove this now-unneeded convenience target. (CLEANFILES, check_DATA): Delete, no longer needed.
2012-09-05maint: remove anachronistic syntax-checkStefano Lattarini
* cfg.mk (sc_no_exec_perl_coreutils): This. Our new testsuite layout (perl tests having '.pl' suffix, shell tests having '.sh' suffix) makes it basically impossible to run into the issue this check guarded against.
2012-09-05maint: remove duplicated declaration of the 'sc_check-AUTHORS' targetStefano Lattarini
* cfg.mk: Here.
2012-09-05tests: remove the unused 'root-hint' targetStefano Lattarini
* tests/Makefile.am (root-hint): Here. The interested user can see the reasons why some tests are skipped by looking at the messages they display on the console; here's an excerpt: ... PASS: misc/id-groups.sh id-setgid.sh: skipped test: must be run as root SKIP: misc/id-setgid.sh PASS: misc/md5sum.pl ... PASS: df/total-verify.sh 2g.sh: skipped test: very expensive: disabled by default SKIP: du/2g.sh ... Clear enough, and more specific and precise that a generic "some tests might need to be run as root" message. And if that user is interested in making those tests run anyway, he'll just take a look to the README files to look for info. So there's no reason to pollute the stdout with another "hint" that is subsumed by those messages, and that might go unnoticed anyway. Moreover, and possibly more importantly, that hint wasn't being displayed anyway, even before this change! That's because the 'root-hint' target was listed as prerequisite for the 'check-recursive' target, which however was not a dependency of the 'check' target in 'tests/Makefile.am', because that file contains no $(SUBDIRS) definition.
2012-09-05tests: use suffix, not exec-bit, to tell which files are testsStefano Lattarini
* tests/Makefile.am (vc_exe_in_TESTS): Adjust to look, in the 'tests/' subdirectory, for files that have one of the extensions listed in $(TEST_EXTENSIONS), rather than for executable files.
2012-09-05maint: make vc_exe_in_TESTS also work in VPATH buildsStefano Lattarini
* tests/Makefile.am (vc_exe_in_TESTS): It is easy to adjust this recipe to also work in VPATH setups, also thanks to modifications done by previous changes.
2012-09-05maint: remove useless dependency for vc_exe_in_TESTSStefano Lattarini
* tests/Makefile.am (vc_exe_in_TESTS): No need to depend on Makefile: this target is .PHONY, so it is always run anyway.
2012-09-05maint: avoid parsing of Makefile.am from vc_exe_in_TESTSStefano Lattarini
* tests/Makefile.am (TESTS): Rename ... (all_tests): ... like this, so that we'll still be able to know the complete list of our tests even if the user overrides TESTS from the command line (which he's allowed to do by the test harness API). (root_tests): Rename ... (all_root_tests): ... like this, for similar reasons. (TESTS, root_tests): Redefine their defaults to to $(all_tests) and $(all_root_tests) respectively. (vc_exe_in_TESTS): It can now safely use $(all_tests) to get the complete list of test cases according to the Makefile, instead of having to resort to "parsing" of Makefile.am. (EXTRA_DIST): Use $(all_tests), not $(TESTS). (v_, w_): Delete, no longer needed.
2012-09-05build: use 'check-local' to extend the 'check' targetStefano Lattarini
* tests/Makefile.am (check-local): Here, by making this depend on 'vc_exe_in_TESTS' ... (check): ... rather than making this depend on them. While the old usage worked, it relied on an implementation detail rather than on documented behavior. * src/local.mk (check-local): Similarly, make this depend on 'check-README' and 'check-duplicate-no-install' ... (check): ... rather than on this.
2012-09-02scripts: autotools-install: allow user-specified make programStefano Lattarini
* scripts/autotools-install: Honor $MAKE. This might be useful on systems where the make implementation available in $PATH by default is limited (Solaris) or broken (HP-UX).
2012-09-02scripts: autotools-install: style and portability fixesStefano Lattarini
* scripts/autotools-install: Here.
2012-09-02touch: line up long option in --help textBenno Schulenberg
* src/touch.c (usage): Indent --time=... to line up with all of the other long options.
2012-09-02maint: disable sc_proper_name_utf8_requires_ICONV testJim Meyering
It would still pass, but would print many diagnostics like this: Can't open src/Makefile.am: No such file or directory. * cfg.mk (local-checks-to-skip): Temporarily disable a test. This test will need to be adapted to work with a non-recursive build set-up, in which there is no Makefile.am alongside each program. Reported by Bernhard Voelker.
2012-09-02maint: accommodate upcoming, expanded list of warnings from gnulibJim Meyering
* configure.ac: Disable a new gcc warning, -Wsuggest-attribute=format, since it triggers on copy.c (which I'm not inclined to adjust) and factor.c's use of vfprintf which would appear to require a change to stdio.h.
2012-09-01maint: fix build_programs definition not to use "make -C src ..."Stefano Lattarini
* dist-check.mk (built_programs): There's no need to issue recursive make calls in 'src/' to define this (in fact, that works no longer now that 'src/Makefile.am' is gone). Simply define this to the sorted contents of $(bin_PROGRAMS), with the 'src/' prefix and the $(EXEEXT) suffix (if any) removed. Reported by Jim Meyering.
2012-09-01build: restore handling of space-tainted build directory nameJim Meyering
* man/local.mk: With commit v8.19-84-g08cf455, man page creation would fail when using a build directory name containing e.g., spaces.
2012-09-01build: make each man/prog.1 depend on src/prog, not src/prog.cJim Meyering
* man/local.mk: Creating a prog.1 man page requires running src/prog --help. List the exceptions, e.g., install.1 depends on src/ginstall and arch.1 depends on src/uname.
2012-09-01maint: check-programs-vs-x: avoid a new syntax-check failureJim Meyering
* cfg.mk (check-programs-vs-x): The new variable, $(all-progs-but-lbracket) contains libstdbuf.so, and it does not have a corresponding .x file, so exempt it.
2012-09-01maint: avoid distcheck failure by properly cleaning $(ALL_MANS)Jim Meyering
* man/local.mk (distclean-local): Remove $(ALL_MANS) when doing a VPATH build. If it's not done, generated manpages can be left around in the build directory after a "make distclean", causing failures in "make distcheck".
2012-09-01maint: port manpages generation to VPATH buildsStefano Lattarini
* man/local.mk (.x.1): Use '$(MKDIR_P)' rather than bare 'mkdir' where appropriate. Reported by Jim Meyering.
2012-09-01build: fix VPATH issues in C compilationJim Meyering
* src/local.mk (AM_CPPFLAGS): Add 'src' to the directories that are searched for #include'd files.
2012-09-01maint: simplify declaration of "libexec" programsStefano Lattarini
* configure.ac: No need to use 'gl_ADD_PROG' and an indirection variable '$optional_pkglib_progs' to declare the 'libstdbuf.so' "libexec" program; the decision to whether compile that program is not up to the user, but it only and simply depends on whether the 'stdbuf' "bin" program is to be built or not.
2012-09-01build: $(mandeps): new, to factor out man pages dependenciesStefano Lattarini
* man/local.mk (mandpep): Rename ... (mandeps): ... like this. Make $(ALL_MANS) depend on its content. List 'src/system.h' in here, instead of making $(ALL_MANS) depend on it explicitly. (man/*.1): No need to list $(mandep) among the dependencies any longer.
2012-09-01build: enhance man pages cleaning and dependenciesStefano Lattarini
* man/local.mk: All of the manpages should depend on 'src/system.h', and all of them should be cleaned by "make maintainer-clean", that is, added to MAINTAINERCLEANFILES. Make it be so. Some minor cosmetic tweakings and reorderings while at it.
2012-09-01build: simplify: get rid of yet some more indirection variablesStefano Lattarini
* configure.ac: Adjust and improve few comments. (MAN): Rename ... (man1_MANS): ... to this. Ensure it isn't initialized in all Makefiles (which would lead to spurious errors), by calling AM_SUBST_NOTMAKE on it. Also call AM_SUBST_NOTMAKE on 'EXTRA_MANS', for consistency. * man/local.mk (man1_MANS): Simply define to '@man1_MANS@'.
2012-09-01build: rename dist_man1_MANS -> man1_MANSStefano Lattarini
And list $(man1_MANS) directly in $(EXTRA_DIST) instead. This is similar to what is done for $(EXTRA_MANS), thus improving consistency and readability. * man/local.mk (dist_man1_MANS): Rename ... (man1_MANS): ... like this. (EXTRA_DIST): Add its contents. * cfg.mk (check-x-vs-1): Fix a botched comment.
