2012-01-01maint: update all copyright year number rangesJim Meyering
Run "make update-copyright".
2012-01-01tests: change copyright year from 2011 to 2012 in sample-testJim Meyering
This file is special. We don't want to use a range, but merely the current year number. * tests/sample-test: s/2011/2012/
2011-12-31tests: fix a missing-dependency problemJim Meyering
* tests/check.mk (.built-programs): Depend on src/Makefile.am, so that when we add a program, this file is updated, and the new program is tested via misc/help-version. Spotted by Pádraig Brady.
2011-12-30build: avoid spurious test.c warning with -Wsuggest-attribute=pureJim Meyering
* src/test.c: Add pragma to suppress gcc-4.6.2's warning that "advance" might be candidate for attribute 'pure'.
2011-12-28tail: avoid theoretically undefined behaviorJim Meyering
* src/tail.c (start_lines): Do not form potentially-invalid address. Use safe_read's return value as a pointer offset only after ensuring that it is not SAFE_READ_ERROR (size_t)(-1). Spotted by coverity. Also, move declaration of "p" to be closer to first use.
2011-12-28tests: also unset _STDBUF_E, _STDBUF_I and _STDBUF_OJim Meyering
* tests/envvar-check (vars): Add these to the list of envvars we ignore: _STDBUF_E, _STDBUF_I, _STDBUF_O, used by libstdbuf.
2011-12-26doc: homologize ch{con,grp,mod,own} option descriptionsPádraig Brady
* src/chgrp.c (usage): Group associated options together, to aid users. Also minimize the differences between individual messages across these four commands, to aid translators. * src/chmod.c: Likewise. * src/chown.c: Likewise. * src/chcon.c (usage): Likewise. Document the --dereference option. Suggested by Paul Eggert and Jari Aalto
2011-12-26stat,tail: recognize new FS type: pipefsJim Meyering
* src/stat.c (human_fstype) [S_MAGIC_PIPEFS]: New case. * NEWS (Bug fixes): Mention this.
2011-12-24doc: stat: clarify that %t and %T expand to the file system typeJim Meyering
* src/stat.c (usage): Mention "file system type", not just "type" for %t and %T. Do not capitalize the first letter of each description.
2011-12-23tail: with -f, use polling when a file is on an FS of unknown typeJim Meyering
Before, we would use inotify in that case, which would work as long as updates were taking place locally, but not at all when remote. Move hard-coded list of known remote FS types into a more maintainable table in stat.c, alongside the list of FS names and magic numbers. Generate a new is_local_fs_type function. * src/Makefile.am (fs-is-local.h): New rule, generated file. * src/extract-magic: Revamp to parse local/remote keyword after each magic number in src/stat.c's case statements. Accept new --local option. * src/.gitignore: Ignore the generated fs-is-local.h. * src/tail.c [HAVE_INOTIFY]: Include fs-is-local.h. (fremote) [HAVE_INOTIFY]: Use the new function in place of the switch stmt with hard-coded list of FS types. Emit a warning when processing a file on a file system of unknown type. * NEWS (Changes in behavior): Mention it. Suggested by Sven Breuner.
2011-12-22doc: update README-release with process to check for new FS magicJim Meyering
* README-release: Run the Makefile rule that checks for new file system magic numbers.
2011-12-22tail,stat: add support for FhGFSJim Meyering
* src/stat.c (human_fstype): Add a case: fhgfs, 0x19830326. * src/tail.c (fremote): Add S_MAGIC_FHGFS. * NEWS (Bug fixes): Update the entry for GPFS to mention FhGFS, too. Reported by Sven Breuner.
2011-12-20doc: improve factor exampleJim Meyering
* doc/coreutils.texi (factor invocation): Adjust example to use $(...) consistently, not a mix of `...` and $(...). Separate the computation of the product and the actual factorization, so the timing of the latter doesn't include the cost of the former.
2011-12-17build: remove now-useless code from bootstrap.confJim Meyering
* bootstrap.conf (bootstrap_epilogue): Remove now-unnecessary, snippet that edited gnulib-tests/gnulib.mk. This snippet was rendered unnecessary by commit v8.14-73-g5bf2c0e.
2011-12-17build: merge in bootstrap changes from gnulibJim Meyering
* bootstrap: Pull in the combination of gnulib's "bootstrap: detect tools required by gnulib-tool" patch and the related fix.
2011-12-14du: -x should not count files in other file systemsPaul Eggert
This fixes Bug#10293, which I guess was introduced in commit 95c948b06a dated 2003-10-02. * NEWS: Document fix. * src/du.c (process_file): Don't count files in different file systems if -x is given. * tests/du/one-file-system: Test for this bug.
2011-12-12doc: document 'touch' and timestamps betterPaul Eggert
* doc/coreutils.texi (touch invocation): Explain file timestamps better. Problem reported by Nelson H.F. Beebe (Bug#7999).
2011-12-12ls: give a more useful diagnostic for a bogus --time-style argJim Meyering
* src/ls.c (decode_switches): Replace our use of XARGMATCH with open-coded version so that we can give a better diagnostic. * tests/ls/time-style-diag: New file. * tests/Makefile.am (TESTS): Add it. Reported by Dan Jacobson in http://bugs.gnu.org/10253 with suggestions from Eric Blake and Paul Eggert.
2011-12-09maint: remove a misleading comment from shred.cJim Meyering
* src/shred.c: Remove obsolete TODO comment. The first two and the last item were done, adding --recursive (-r) is neither necessary nor appropriate, and I don't want to add --interactive. I don't see a need for the others. Prompted by comments from Amr Ali.
2011-12-08ls: be responsive to interrupts when color-listing large directoriesJim Meyering
Starting with commit adc30a83, when using --color, ls inhibited interrupts to avoid corrupting the state of an output terminal. However, for very large directories, that inhibition rendered ls uninterruptible for too long, including a potentially long period even before any output is generated. * src/ls.c: Two phases of processing are time-consuming enough that they can provoke this: the readdir loop and the printing loop. The printing was supposed to be covered by a call to process_signals in (print_name_with_quoting): ... but that call was mistakenly guarded by a condition that might be false for many or even all files being processed. Call process_signals unconditionally. (print_dir): Also call process_signals in the readdir loop. * NEWS (Bug fixes): Mention it. Reported by Arkadiusz Miśkiewicz in http://bugs.gnu.org/10243 Co-authored-by: Eric Blake <eblake@redhat.com>
2011-12-05ln: clarify usage of -L, -n, -TPaul Eggert
* src/ln.c (usage): Use clearer wording to describe the -L, -n, and -T options (Bug#9896).
2011-12-05maint: don't assume GNU make \# syntax (fix previous)Paul Eggert
* src/Makefile.am (fs_normalize_perl_subst, fs-magic, fs-kernel-magic): Undo previous patch; it missed a \#. (fs_normalize_perl_subst): Use \043 rather than \#. \043 is portable to all ASCIIish platforms, whereas \# is portable only to platforms that are compatible with GNU make (and are incompatible with POSIX make). Porting this to EBCDIC is left as an exercise for the reader....
2011-12-05maint: sort, stat: remove unused parametersJim Meyering
* src/sort.c (struct thread_args) [is_lo_child]: Remove member. (sortlines): Remove unused parameter, "is_lo_child". Update callers. * src/stat.c (out_epoch_sec): Mark unused parameter. (do_statfs, do_stat): Remove unused parameter, "terse". Update callers.
2011-12-05maint: don't assume GNU make \# syntaxPaul Eggert
* src/Makefile.am (fs_normalize_perl_subst): Don't make unportable assumption about \# in the right hand side of a macro definition. This works with GNU make, but not with POSIX make. Problem reported by Basavaraj B (Bug#10220). (fs-magic, fs-kernel-magic): Do the #-substitution here instead.
2011-12-04od,test: address warnings from gcc's -Wjump-misses-initJim Meyering
* src/test.c (unary_operator): gcc reported that initializations in two case statements were skipped. Enclose in braces. * src/od.c (decode_one_format): Likewise.
2011-12-04maint: remove redundant usage declarations (-Wredundant-decls)Jim Meyering
* src/csplit.c (usage): Remove declaration. * src/ls.c (usage): Likewise. * src/pr.c (usage): Likewise.
2011-12-03maint: add missing ":" after "License" in local gnulib module filesJim Meyering
This avoids spurious diagnostics when running our "bootstrap" script. * gl/modules/heap: Append colon after "License". * gl/modules/randint: Likewise. * gl/modules/randperm: Likewise. * gl/modules/randread: Likewise. Reported by Stefano Lattarini. Diagnosed by Bruno Haible.
2011-12-01doc: fix list of GNU extension date formatsEric Blake
I didn't check how long these were documented as GNU extensions, nor when they were added by POSIX; but since they are all part of POSIX 2008, we no longer need call them out as extensions. The next version of POSIX will standardize %s: http://austingroupbugs.net/view.php?id=169 but as that is not out yet, I didn't change %s. * doc/coreutils.texi (Time conversion specifiers): %R and %z are now POSIX. (Date conversion specifiers): Likewise for %F, %g, %G.
2011-12-01tests: adjust PATH to generally include /sbin and /usr/sbinBernhard Voelker
Commit 5eeaca94 added /sbin to the PATH for tests using mkfs. For other tests, e.g. tests/cp-fiemap-perf using filefrag, we need /usr/sbin also. Add both directories generally for the tests, "since many of us always augment our PATH with all of the sbin paths all of the time anyway" (Bob in http://lists.gnu.org/archive/html/coreutils/2011-11/msg00107.html). The previous commit is hereby obsolete. * tests/init.cfg (sanitize_path_): Add /sbin and /usr/sbin to PATH unless already included. Needed for tests using admin tools like mkfs and filefrag on systems where the user's environment does not have these directories in the PATH. * tests/init.cfg (require_mkfs_PATH_): Remove obsolete function. * tests/cp/cp-a-selinux: Remove require_mkfs_PATH_ call. * tests/cp/cp-mv-enotsup-xattr: Likewise. * tests/cp/sparse-fiemap: Likewise. * tests/mkdir/writable-under-readonly: Likewise. * tests/rm/read-only: Likewise.
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.
2011-11-29build: update gnulib for syntax-check improvementEric Blake
Commit 5b3e538 proved useful enough to migrate to gnulib after enhancing it to be more generic, which in turn pointed out that commit a2c811db missed an offender. * gnulib: Update to latest. * cfg.mk (sc_prohibit_reversed_compare_failure): Delete, now that gnulib provides it. * tests/ls/dangle: Fix last offender.
2011-11-29build: update gnulib to fix build failure with --enable-gcc-warningsJim Meyering
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.
2011-11-28build: update gnulib for const+pure attributesJim Meyering
2011-11-27tests: add a syntax check for last week's global changeJim Meyering
Last week I made a global change, commit a2c811db, `tests: use "compare exp out", not "compare out exp"', but forgot to add a corresponding syntax check rule. Without that, it is far too easy to add a new test or to merge in an old one that would be non-conforming. Obviously this is only a heuristic, since it relies on the expected-output file to have a name that starts with "exp". * cfg.mk (sc_prohibit_reversed_compare_failure): Prohibit use of compare with reversed arguments.
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.
2011-11-24maint: bootstrap: run autopoint and libtoolize *before* gnulib-toolJim Meyering
* bootstrap (AUTOPOINT, AUTORECONF): Factor out definitions. Run autopoint and libtoolize *before* gnulib-tool. After it, run an abbreviated autoreconf, rather than a loop around all tools. * bootstrap.conf (gnulib_tool_option_extras): Add both --symlink and --makefile-name=gnulib.mk. Remove stray use of $bt. * lib/Makefile.am: Initialize all of the following so that generated code in gnulib.mk may use += to append to those variables: AM_CFLAGS, AM_CPPFLAGS, BUILT_SOURCES, CLEANFILES, EXTRA_DIST, MAINTAINERCLEANFILES, MOSTLYCLEANDIRS, MOSTLYCLEANFILES, SUFFIXES, noinst_LIBRARIES.
2011-11-24maint: bootstrap: remove some now-unneeded codeJim Meyering
This bootstrap script arose back when gnulib-tool was young. Since then, it has seen improvements that render much of this script unnecessary. In particular, it can now make symlinks to the files it uses. Also, I no longer see as much value in marking files as read-only via comments. * bootstrap (slirp, bt_mark_as_generated): Remove.
2011-11-24maint: use gnulib's gettext-h, not the gettext moduleJim Meyering
* bootstrap.conf (gnulib_modules): Use gnulib's gettext-h, not the gettext module. Not only is gettext-h far smaller (it has far fewer dependencies than the gnulib module), but it does not suffer from the problem with the gettext module whereby it adds a -I.../intl option to compilation flags. That can provoke warnings, since we don't have such a directory. We used to work around that via a hack in bootstrap, but that was ugly and inefficient.
2011-11-24maint: append many lib/ and m4/ names to .gitignoreJim Meyering
2011-11-24build: update gnulib submodule to latest for fixed stdalign testJim Meyering
2011-11-23scripts: commit-msg: tweak 72-column test to avoid a false-positiveJim Meyering
* scripts/git-hooks/commit-msg: Don't warn about a line that is longer than 72 if it is a comment. Git-generated comments would occasionally trigger this.
2011-11-23build: update gnulib and tests/init.shJim Meyering
* gnulib: Update. * tests/init.sh: Update from gnulib.
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.
2011-11-22tests: use "compare exp out", not "compare out exp"Jim Meyering
Likewise, when an empty file is expected, use "compare /dev/null out", not "compare out /dev/null". I.e., specify the expected/desired contents via the first file name. Prompted by a suggestion from Bruno Haible in http://thread.gmane.org/gmane.comp.gnu.grep.bugs/4020/focus=29154 Run these commands: git grep -l -E 'compare [^ ]+ exp' \ |xargs perl -pi -e 's/(compare) (\S+) (exp\S*)/$1 $3 $2/' git grep -l -E 'compare [^ ]+ /dev/null' \ |xargs perl -pi -e 's/(compare) (\S+) (\/dev\/null)/$1 $3 $2/' * tests/chgrp/no-x: As above. * tests/chmod/no-x: Likewise. *

2011-11-20maint: revert "build: update gnulib submodule to latest"Jim Meyering
Don't update to latest from gnulib just yet. This reverts commit 173f4d9bd628fb771eaeca3d2fef97dcd71fedb8. In particular, manywarnings is too aggressive.
2011-11-20build: update gnulib submodule to latestJim Meyering
2011-11-20maint: make generated THANKS file read-onlyJim Meyering
* Makefile.am (THANKS): Make generated file read-only.
