2012-11-04build: don't assume uintmax_t is 64 bitsPádraig Brady
This was not seen to be an issue in practise, but to make the code more robust, don't assume uintmax_t is 64 bits. * src/factor.c (W_TYPE_SIZE): Define based on integer limits. * src/make-prime-list.c (output_primes): Define format width based on integer limits.
2012-11-04build: don't rely on support for '%j' printf formatPádraig Brady
* src/factor.c (print_uintmaxes): Replace with PRIuMAX. * src/join.c (check_order): Likewise. * cfg.mk (sc_check-j-printf-format): Add a syntax-check rule to flag new cases of this.
2012-11-04build: don't rely on support for '%*j' printf formatPádraig Brady
* src/make-prime-list.c: Hardcode the uintmax_t width to 16 hex digits (64 bit), to avoid this compile issue on HPUS systems at least.
2012-11-01tests: fix syntax error in setuidgid_has_perm_Bernhard Voelker
An invalid sed expression lead to the following error: + sed -n 'ls/.* //p' sed: -e expression #1, char 2: extra characters after command Use "one" instead of "el". Bug introduced in v8.19-111-g51a4b04. * init.cfg (setuidgid_has_perm_): s/ls/1s/. * NEWS (Build-related): Mention the fix.
2012-10-27tests: shorten factor's inordinately-long test file namesBernhard Voelker
Besides what the subject says, this commit moves the test data for the factor tests from tests/local.mk into the directory tests/factor/ where it belongs. * tests/local.mk (EXTRA_DIST): Add new tests/factor/create-test.sh. (p,q,t1,t2) Factor out the factor-related magic numbers. (factor_tests): Rename the test names to t{00..36}.sh. Factor out the triples of test data. ($(factor_tests)): Add dependency to new tests/factor/create-factor.sh. Call that script to generate the test scripts. * tests/factor/run.sh: Turn this script into a template, and therefore remove it's executable permission bit. Add template variables START, END and CKSUM, replacing the code to split the test data from the test script's file name. Use the new template variables in the call to seq and for creating the exp file. * tests/factor/create-test.sh: Add new script to create the test scripts from the template tests/factor/run.sh. Use test data and magic numbers factored out from the above files. Let the script also change the __TEMPLATE__ line in run.sh to make clear that the test scripts are generated. * cfg.mk (sc_tests_list_consistency): Exempt the new test. (exclude_file_name_regexp--sc_prohibit_test_backticks): Likewise. Improved-by: Stefano Lattarini Improved by: Jim Meyering
2012-10-26build: man page generation: degrade gracefully when perl is lackingStefano Lattarini
Since commit v8.19-118-g57da212, our 'dist-hook' rule tweaked the distributed Makefile.in to make each man page 'man/foo.1' depend on the corresponding source 'src/foo.c' rather than the corresponding program 'src/foo'. That was done to accommodate systems without perl, which cannot run help2man to regenerate the manpage after its corresponding program has been built. This seems a right and proper graceful degradation, in that the man pages dependencies are still 100% correct in a git checkout, while being more lax but "more portable" in a distribution tarball. Alas, that is not the case in practice, as it turns out the tweaked Makefile makes the building of man pages unreliable and potentially incorrect! In fact, assume that instead of the correct a dependency: man/ls.1: src/ls we have the laxer one: man/ls.1: src/ls.c and think of what happens if a user modifies, say, 'src/ls.c', and then runs "make -j4" to rebuild everything. The make process will see that it has to rebuild the man page 'man/ls.1' (because its prerequisite 'src/ls.c' has changed), but won't see that it has to rebuild 'src/ls' *before* re-running 'help2man' to generate that man page; so, if 'man/ls.1' is rebuilt before 'src/ls' (which can happen with concurrent make), our user will get either a build error (if 'src/ls' did non exist) or, worse, a man page with an up-to-date timestamp but an out-of-date content. And what's even worse in all of this is that this problem will be present also for users who have perl installed: this is not a "graceful degradation" at all! In our situation, the best and simplest way to implement a graceful degradation it to keep the correct dependencies for man pages (that is, "man/ls.1: src/ls"), and if perl is not present, just generate dummy man pages reporting that built-time issue and redirecting the user back to either the info documentation or the '--help' output. As a consequence of this change, we also stop distributing man pages, since they will now be generated unconditionally. * Makefile.am (do-not-require-help2man): Remove. (dist-hook): Don't depend on it. * man/local.mk: Remove an obsolete comment. (EXTRA_DIST): Stop distributing generated man pages. ($(EXTRA_MANS)): This no longer needs to depend on $(all_programs). (MAINTAINERCLEANFILES): $(ALL_MANS) Do not list it here, and ... (CLEANFILES): ... list it here, instead. (.x.1): Instead of warning if perl is missing, but then trying to run 'help2man' unconditionally, simply run ... (run_help2man): ... the command referenced by this new variable, that expands to a proper invocation of 'help2man' if perl is present, and to an invocation of a shell script generating a dummy manpage if it is not. (EXTRA_DIST): Distribute that shell script. * man/dummy-man: New shell script. * NEWS (Build-related): Mention this. Fixes coreutils http://bugs.gnu.org/12715.
2012-10-25maint: tweak sc_check-I18N-AUTHORSJim Meyering
* cfg.mk (sc_check-I18N-AUTHORS): Remove unnecessary subshell; add a self-explanatory diagnostic.
2012-10-25maint: remove an obsolete test commentJim Meyering
* tests/du/bind-mount-dir-cycle.sh: Remove obsolete comment spotted by Gilles Espinasse.
2012-10-25pr: fix -n to pad consistently and not crashPádraig Brady
* src/pr.c: Replace the code to truncate the most significant digits of line numbers, with much simpler string manipulation that supports arbitrary widths. Before this, specifying a width >= 32 to -n would result in a divide by zero error. Also remove the inconsistent padding with zeros and spaces, which would result in zero padding for widths 12 and 15. * tests/pr/pr-tests.pl: Added a test to ensure no zero padding, and also a test for the divide by zero case. * NEWS: Mentioned the fix Reported by Ondrej Oprala
2012-10-25build: ensure factor links the iconv libraryPádraig Brady
* src/local.mk (src_factor_LDADD): Append $(LIBICONV). * crg.mk (sc_check-I18N-AUTHORS): A new syntax check rule to ensure we add LIBICONV where appropriate. * THANKS.in: Add the reporter. Reported by Christian Jullien Syntax check suggested by Jim Meyering
2012-10-25maint: refactor tests/misc/pr.pl into tests/pr/pr-tests.plPádraig Brady
* tests/misc/pr.pl: Refactor this test into ... * tests/pr/pr-tests.pl: ... here. * tests/local.mk: Remove the reference to the removed test Improved by Jim Meyering
2012-10-24build: do not redefine _FORTIFY_SOURCEMike Frysinger
When _FORTIFY_SOURCE is defined by the compiler or via flags, as it is on Gentoo, do not override it. Otherwise we get many redefinition warnings. * configure.ac (FORTIFY_SOURCE): Check if _FORTIFY_SOURCE is defined. This addresses http://bugs.gnu.org/12714

2012-10-23build: avoid warnings about unused variables and macrosPádraig Brady
src/factor.c (__GMP_DECLSPEC): Move back from longlong.h to treat consistently with other stub macros. (__GMP_GNUC_PREREQ): Reference to avoid -Wunused-macros warning. (__GMP_DECLSPEC): Likewise. (ASSERT): Likewise. (__clz_tab): Likewise. (factor_using_division): Mark a variable as unused. (mulredc): Likewise. (mulredc2): Likewise. (divexact_21): Likewise.
2012-10-23build: avoid compile warnings in factor.c on some systemsPádraig Brady
* src/factor.c (factor_using_pollard_rho2): On some systems (like sparc) we need to promote all addmod2() parameters to uintmax_t to avoid warnings.
2012-10-23build: avoid build failure on some sparc systemsPádraig Brady
* src/longlong.h: Restrict some sparc assembly variants to sparc V9. This was seen to be an issue with newer sparc systems with default gcc CPU options.
2012-10-23tests: correctly restrict factor test without GMPPádraig Brady
* tests/misc/factor.pl: Correct the precedence and regular expression in the command to check for GMP.

* HACKING: Add "cd coreutils" after the git clone command. Copyright-paperwork-exempt: Yes
2012-10-09factor: fix integer validation and GMP fallbackPádraig Brady
In the recent factor rewrite, the GMP code wasn't actually used; just an error was printed on integer overflow. While fixing that it was noticed that correct input validation wasn't done in all cases when falling back to the GMP code. * src/factor.c (print_factors) Fallback to GMP on overflow. (strto2uintmax): Scan the string for invalid characters, so that case can be detected independently of overflow. Return an error when an empty string is passed. Also allow leading spaces and '+' in input numbers. * tests/misc/factor.pl: Ensure the GMP code is exercised when compiled in. Also add a test to verify leading spaces and '+' are allowed.
2012-10-08build: support older GMP versionsPádraig Brady
The new factor code introduced usage of mpz_inits() and mpz_clears(), which are only available since GMP >= 5, and will result in a compile error when missing. * m4/gmp.m4 (cu_GMP): Define HAVE_DECL_MPZ_INITS appropriately. * src/factor (mpz_inits): New function, defined where missing. (mpz_clears): Likewise.
2012-10-07maint: avoid warning from gcc's -Wunused-macrosJim Meyering
On some systems, -Wunused-macros would warn about two macros: src/factor.c:148:0: warning: macro "__clz_tab" is not used src/factor.c:126:0: warning: macro "UHWtype" is not used * src/factor.c: Add a use to placate gcc.
2012-10-05build: avoid link failure when strerror is replacedJim Meyering
When building the new make-prime-list program on a system for which strerror is defined to rpl_strerror, we'd get a link failure. The problem is that we're including <config.h> for some definitions, but do not want the rpl_ ones, since this particular program must not be linked against gnulib (aka libcoreutils.a). This did not arise on Fedora 17 or 18, but did on Debian wheezy/sid. * src/make-prime-list.c (strerror): #undef. Build failure introduced by commit v8.19-152-gcf67e4c.
2012-10-04factor: 25% speed-up, on outputJim Meyering
* src/factor.c (print_factors_single): Use fputs and umaxtostr rather than printf with "%ju". This reduced the time required to compute and print the factors of the first 10^7 integers from over 8 seconds to 5.75s. Run this command: seq $((10**7)) | env time factor > /dev/null
2012-10-04factor: merge with preexisting factor; integrate tests; avoid warningsJim Meyering
* src/factor.c: Renamed from factor-ng.c, with the following changes: Adjust copyright header to be consistent with others. Use xmalloc and xrealloc, to avoid segv upon OOM. Switch back to using readtokens to handle input. Diagnose invalid inputs. s/fprintf+exit/error/ (print_factors): Add comments. (strto2uintmax): Return strtol_error, not int. (read_item): Remove, no longer used. (main): Use atexit(close_stdout) so that we don't ignore failed write. * cfg.mk: Exempt src/longlong.h from several tests. Exempt run.sh from the test-list-consistency test. Exempt make-prime-list.c from numerous tests, since we won't be making it conform: it must not link with libcoreutils.a. Exempt factor-ng.c from the no-upper-case error message test. * AUTHORS (factor): Add Torbjörn and Niels. * tests/local.mk (factor_tests): Encode the 37 tests. ($(factor_tests)): Rule to generate a test script for each test. * tests/factor/run.sh: New script, marked as very expensive. * .gitignore: Ignore new generated files. * src/local.mk (src/primes.h): New rule. (noinst_PROGRAMS): Add make-prime-list. (noinst_HEADERS): Add longlong.h. Remove all wheel-related rules and files. * src/wheel-gen.pl: Remove file. maint: mark set-but-not-used variables with ATTRIBUTE_UNUSED * src/factor-ng.c (redcify, prime_p, isqrt2): Mark them, so we don't have to disable -Wunused-but-set-variable. maint: use __builtin_expect only if __GNUC__ * src/factor-ng.c (LIKELY, UNLIKELY) [__GNUC__]: Add #ifdef guard. build: avoid warning about unused macro * src/factor-ng.c (__GMP_DECLSPEC): Don't define here * src/longlong.h (__GMP_DECLSPEC): Define if not already defined.

2012-10-04maint: make-prime-list: do not ignore write failureJim Meyering
Even though this is just a helper program that is run solely to create primes.h, it should not ignore a write failure. Normally we would simply call atexit (close_stdout), but we cannot do that from this helper program, since it must be built before the generated header, primes.h. If we were to make the linking of make-prime-list depend on libcoreutils.a, that would add all lib/*.o files to the list of dependents of $(BUILT_HEADERS). Then, since there is currently no provision to ensure that a file like lib/stdio.h (another built header) is built before the first lib/*.o file that also includes <stdio.h>, some lib/*.o files would be built before lib/stdio.h and some after. The former would provoke link failures due to undefined rpl_* functions. * src/make-prime-list.c: Include <errno.h>. (fclose): Undef, so that a definition to rpl_fclose does not cause a link failure. (main): Per the above, in this exceptional case, we check for fclose and ferror failure manually, and don't worry about the ferror-only failure case in which errno may not be relevant.
2012-10-04maint: make-prime-list: avoid -Wsuggest-attribute=const warningJim Meyering
* src/make-prime-list.c: Include <config.h>. (binvert): Add _GL_ATTRIBUTE_CONST.

2012-10-03build: remove redundant dependency: $(PROGRAMS): lib/libcoreutils.aJim Meyering
* src/local.mk: Remove the above dependency. A soon-to-be-added new program, make-prime-list, must not depend on that, since it is used to create a BUILT_SOURCES file. That dependency is already handled via the ..._LD_ADD variables, and so that redundant dependency has so far been harmless.
2012-09-30du: avoid abort on systems for which ->me_type is not malloc'dJim Meyering
On some systems (notably, BSD-based, like at least OpenBSD 4.9), the me_type member does not come from the heap. * src/du.c (fill_mount_table): Free the ->me_type member only when it was malloc'd, i.e., when ->me_type_malloced is nonzero. Bug introduced via commit v8.19-2-gcf7e1b5. Reported as http://bugs.gnu.org/12542.

2012-09-28cp: fix the --no-preserve=mode optionOndrej Oprala
The --no-preserve=mode option did not do what its name implies: it would mistakenly preserve permission mode bits. * NEWS: Mention the fix. * TODO: Remove an entry. * src/copy.c (copy_reg): Add a condition to properly handle the --no-preserve=mode option for files (copy_internal): Add a condition to properly handle the --no-preserve=mode option for directories. * src/copy.h (struct cp_options): Add a new boolean. * src/cp.c (cp_option_init,decode_preserve_arg): Set the new boolean value according to specified options. * src/install.c (struct cp_options): Initialize the new boolean. * src/mv.c (struct cp_options): Initialize the new boolean. * tests/cp/preserve-mode.sh: Add a new test. * tests/cp/link-preserve.sh (-a --no-preserve=mode): Adjust the expected perms: now, --no-preserve=mode overrides the --preserve=mode that is inherent in -a, as it should. * tests/local.mk: Add the new test to the list.
2012-09-24timeout: handle signals more transparentlyPádraig Brady
This was originally attempted in commit v8.12-117-g5a647a0, but reverted before release because of the unreliability of disabling core dumps using setrlimit() on Linux kernels. This new version instead uses prctl() where available to more reliably disable core dumps for the timeout process. * m4/jm-macros.m4: Define HAVE_SETRLIMIT and HAVE_PRCTL. * src/timeout.c (disable_core_dumps): A new function that disables coredumps using prctl or setrlimit if available. (main): If the child exited with a signal and we can disable core dumps, then raise that signal to the timeout process itself, so that callers may also see the signal status. Also print a message indicating when the monitored command dumped core, as that information is lost in the signal propagation through timeout.
2012-09-24dd: new option, status=none to suppress output statisticsPozsár Balázs
* src/dd.c (STATUS_NONE): A new bitmask combining all STATUS_ options, thus used to suppress all informational output. (struct symbol_value statuses): Expose the "none" option, corresponding to the STATUS_NONE bitmask above. (print_stats): Return early if STATUS_NONE is specified. Also move the call to gethrxtime() down so that it's only called when needed. (usage): Describe the new options. * doc/coreutils.texi (dd invocation): Likewise. * NEWS: Mention the new feature. * tests/dd/misc.sh: Ensure the new option works.
2012-09-23tail,stat: improve support for vmhgfsJim Meyering
Teach tail -f that it must use polling on vmhgfs file systems, and let stat -f --format=%T report the file system type name, "vmhgfs". * src/stat.c (human_fstype): Add a case: vmhgfs, 0xbacbacbc, remote. * NEWS (Improvements): Mention it. * THANKS.in: Update. Reported by Daniel Tschinder in http://bugs.gnu.org/12461.
2012-09-20build: move non-recursive-gnulib-prefix-hack to gnulib; updateJim Meyering
I've moved the non-recursive-gnulib-prefix-hack module to gnulib, with two small improvements, so remove it from here and update gnulib to the latest. * gl/build-aux/prefix-gnulib-mk: Remove file. * gl/m4/non-recursive-gnulib-prefix-hack.m4: Remove file. * gl/modules/non-recursive-gnulib-prefix-hack: Remove file. * gnulib: Update to latest.
2012-09-19rm: be even more careful when using a replacement errno valueJim Meyering
* src/remove.c (excise): The change in commit v8.19-107-gccbd3f3 made the "rm -rf D" (for unreadable dir, D) diagnostic worse on Solaris 10: -rm: cannot remove 'D': Permission denied +rm: cannot remove 'D': File exists That happened because unlinkat would fail with EEXIST there, given an unreadable directory, which made the two tests, tests/rm/unread2 and tests/rm/unreadable fail. Accommodate the EEXIST case, too.
