2015-09-23build: update gnulib submodule to latestPádraig Brady
This includes a change to propagate the 4th "mount root" field from /proc/self/mountinfo from the mountlist module, which is needed in a subsequent commit in df. * gl/lib/regcomp.c.diff: Regenerate against latest gnulib. * gl/lib/regex_internal.c.diff: Likewise. * gl/lib/regex_internal.h.diff: Likewise. * cfg.mk: Exclude diffs from trailing whitespace check, which is generally correct, and now needed.
2015-04-26build: update gnulib submodule to latestPaul Eggert
* bootstrap.conf (gnulib_modules): Add file-has-acl. (buildreq): Bump autopoint and gettext to 0.19.4. * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.19.4. * gl/lib/tempname.c.diff, gl/lib/tempname.h.diff: Merge recent gnulib changes.
2015-02-11build: update to latest gnulibPádraig Brady
This includes a change to require --with-libmount to be used with configure, due to the many libmount dependencies. * bootstrap: Sync with gnulib to exit early on gnulib-tool error. * gl/lib/tempname.c.diff: Adjust for gnulib changes. * gl/lib/tempname.h.diff: Likewise. * gl/modules/tempname: Likewise. * doc/.gitignore: Add new gendocs_template_min gnulib script.
2015-02-03build: fix invalid gnulib patchPádraig Brady
* gl/lib/tempname.c.diff: Fix recent breakage so it applies again. Invalid patch was noticed at http://hydra.nixos.org/eval/1172233 * cfg.mk: Exempt diff files from these "id_est" syntax checks. (sc_ensure_gl_diffs_apply): A new syntax check, to ensure all patches under gl/ apply cleanly. Note we use --fuzz=0 to check patches apply cleanly for safety, due to the patch(1) issue detailed in commit v8.21-117-g46f7e05 * gl/lib/regcomp.c.diff: Rediffed. * gl/lib/regex_internal.c.diff: Likewise. * gl/lib/regex_internal.h.diff: Likewise. * gl/lib/regexec.c.diff: Likewise. * gl/lib/tempname.h.diff: Likewise.
2015-01-31doc,maint: fix use of "i.e." in documentation and commentsBernhard Voelker
To align with all other places (and correct grammar), change all upper-case "I.E." to "I.e.". Furthermore, ensure that "i.e." is followed by a comma. Finally, ensure to use a double-space before "I.e.," at the beginning of a sentence. The following was used to change all offending uses (apart from old ChangeLog files): $ git grep -liF 'i.e.' \ | xargs sed -i \ -e 's/I\.E\./I.e./g' \ -e 's/\. \(I\.e\.\)/. \1/g' \ -e 's/\([Ii]\.e\.\)\( \)/\1,\2/g' \ -e 's/\([Ii]\.e\.\)$/\1,/g' * cfg.mk (sc_prohibit_uppercase_id_est): Add new rule. (sc_ensure_double_space_after_dot_before_id_est): Likewise. (sc_ensure_comma_after_id_est): Likewise. (old_NEWS_hash): Refresh hash via "make update-NEWS-hash". * NEWS: Change use of "id est" abbreviation via the above command. * README: Likewise. * README-prereq: Likewise. * doc/coreutils.texi: Likewise. * gl/lib/rand-isaac.c: Likewise. * gl/lib/tempname.c.diff: Likewise. * man/stdbuf.x: Likewise. * src/cat.c: Likewise. * src/copy.c: Likewise. * src/copy.h: Likewise. * src/cp.c: Likewise. * src/cut.c: Likewise. * src/dd.c: Likewise. * src/df.c: Likewise. * src/fiemap.h: Likewise. * src/longlong.h: Likewise. * src/ls.c: Likewise. * src/numfmt.c: Likewise. * src/pr.c: Likewise. * src/shred.c: Likewise. * src/shuf.c: Likewise. * src/split.c: Likewise. * tests/Coreutils.pm: Likewise. * tests/df/df-symlink.sh: Likewise. * tests/df/skip-rootfs.sh: Likewise. * tests/init.sh: Likewise. * tests/ls/color-norm.sh: Likewise. * tests/misc/basename.pl: Likewise. * tests/misc/ls-misc.pl: Likewise. * tests/misc/md5sum-bsd.sh: Likewise. * tests/misc/shred-exact.sh: Likewise. * tests/misc/sort.pl: Likewise. * tests/misc/stdbuf.sh: Likewise. * tests/misc/tac-continue.sh: Likewise. * tests/rm/r-root.sh: Likewise. * tests/tail-2/symlink.sh: Likewise.
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.
2014-12-25tests: fix error message check on some systemsPádraig Brady
http://hydra.nixos.org/build/18129583 identified (on OS X) an incorrect test assumption in the previous commit. * gl/lib/xdectoint.c (__xnumtoint): Suppress the EINVAL error message as it's redundant in this context. * tests/misc/tail.pl: Suppress _optionally_ appended strerror messages. * tests/fmt/base.pl: Likewise. * tests/pr/pr-tests.pl: Likewise. * tests/split/l-chunk.sh: Likewise.
2014-12-19diagnose too-large numbers betterPádraig Brady
Following on from commit v8.23-82-gaddae94, consistently diagnose numbers that are too large, so as to distinguish from other errors, and make the limits obvious. * gl/modules/xdectoint: A new module implementing xdecto[iu]max(), which handles the common case of parsing a bounded integer and exiting with a diagnostic on error. * gl/lib/xdectoimax.c: The signed variant. * gl/lib/xdectoint.c: The parameterized implementation. * gl/lib/xdectoint.h: The interface. * gl/lib/xdectoumax.c: The unsigned variant. * bootstrap.conf: Reference the new module. * cfg.mk (exclude_file_name_regexp--sc_require_config_h_first): Exclude the parameterized templates. * src/csplit.c: Output EOVERFLOW or ERANGE errors if appropriate. * src/fmt.c: Likewise. * src/fold.c: Likewise. * src/head.c: Likewise. * src/ls.c: Likewise. * src/nl.c: Likewise. * src/nproc.c: Likewise. * src/shred.c: Likewise. * src/shuf.c: Likewise. * src/stdbuf.c: Likewise. * src/stty.c: Likewise. * src/tail.c: Likewise. * src/truncate.c: Likewise. * src/split.c: Likewise. * src/pr.c: Likewise. * tests/pr/pr-tests.pl: Adjust to avoid matching errno diagnostic. * tests/fmt/base.pl: Likewise. * tests/split/l-chunk.sh: Likewise. * tests/misc/shred-negative.sh: Likewise. * tests/misc/tail.pl: Likewise. Also remove the redundant existing ERR_SUBST from test err-6. * tests/ls/hex-option.sh: Check HEX/OCT options. * tests/misc/shred-size.sh: Likewise. * tests/misc/stty-row-col.sh: Likewise.
2014-12-03maint: avoid -fsanitize=undefined warning in rand-isaacPádraig Brady
* gl/lib/rand-isaac.c (isaac_refill): readisaac() purposefully passes unaligned pointers to avoid memory copies. This is only done on platforms where this is defined, so avoid the associated runtime warning generated with -fsanitize=undefined, which is: lib/rand-isaac.c:125:182: runtime error: store to misaligned address 0x63100003d7fd for type 'isaac_word', which requires 8 byte alignment 0x63100003d7fd: note: pointer points here 47 ce ed a4 be be be 00 00 00 00 00 00 00 00 ... ^
2014-07-19maint: fix message translation glitchesPaul Eggert
Problem reported by Sebastian Rasmussen in: http://bugs.gnu.org/18054 * gl/lib/randread.c (randread_error): Don't put multiple string literals inside _(...), as xgettext doesn't support that. * src/chroot.c (main): In diagnostics, don't bother to distinguish between setting the number of supplemental group IDs to a zero or to a nonzero value, as the underlying system call is the same either way. This also makes the string easier to translate correctly.
2014-04-25maint: remove trailing comma from enum to make gl/ c89 compatEdgars Irmejs
* gl/lib/fadvise.c (fadvice_t): This might go to gnulib some day so remove the trailing comma. Fixes http://bugs.gnu.org/17329
2014-03-19maint: fix typo in comment in fadvise.cBernhard Voelker
* gl/lib/fadvise.c: s/the the/the/, indroduced in commit v8.22-40-g4f21182. Promted by sc_prohibit_doubled_word. While at it, also s/be candidate/be a candidate/.
2014-03-13maint: avoid "attribute-const"-suggesting warning from gccJim Meyering
* gl/lib/fadvise.c: Use a pragma to turn off this warning option: -Wsuggest-attribute=const. Without this change, building with --enable-gcc-warnings would evoke this error: lib/fadvise.c:25:1: error: function might be candidate for\ attribute 'const' [-Werror=suggest-attribute=const]
2014-01-02maint: update all copyright year number rangesBernhard Voelker
Run "make update-copyright", but then also run this, perl -pi -e 's/2\d\d\d-//' tests/sample-test to make that one script use the single most recent year number.
2013-09-10build: fix corrupted patch causing bootstrap failuresPádraig Brady
The patch was corrupted in commit v8.21-50-g7b65f8e * gl/modules/tempname.diff: Fix the offsets so that the patch applies cleanly. Note that this was only apparent with patch < 2.6. With patch >= 2.6, patch will not indicate an error applying the second hunk of the patch and silently ignore it. I double checked that all patches now apply cleanly by adjusting gnulib-tool to run patch with --fuzz=0 which might be advisable going forward, even on a per project basis. The silent ignoring of hunks by newer patch(1) has been reported. Fixes http://bugs.gnu.org/15255
2013-07-02maint: refactor SMACK interface to a separate modulePádraig Brady
Consolidate all smack routines and checks in a module. We replace and wrap the most commonly used smack routines, which allows removing ifdefs throughout the code. * gl/lib/smack.h: A new header containing the implementation of the wrapped and replacement routines. Note the is_smack_enabled() routine should be optimized out at compile time when compiled on a system without libsmack. * gl/modules/smack: Describe the new module and move the configure time code here from ... * m4/jm-macros.m4: ... here. * bootstrap.conf: Reference the new module. * src/id.c: Use the routines without ifdefs where possible. * src/ls.c: Likewise. * src/mkdir.c: Likewise. * src/mkfifo.c: Likewise. * src/mknod.c: Likewise.
2013-05-18maint: port --enable-gcc-warnings to clangPaul Eggert
* configure.ac: If clang, add -Wno-format-extra-args and -Wno-tautological-constant-out-of-range-compare. * gl/lib/rand-isaac.c (ind): * gl/lib/randread.c (readisaac): * src/ls.c (dev_ino_push, dev_ino_pop): * src/sort.c (buffer_linelim): * src/system.h (is_nul): * src/tail.c (tail_forever_inotify): Rewrite to avoid casts that clang dislikes. It's good to avoid casts anyway. * src/expr.c (integer_overflow): Declare only if it exists. (die): Remove; unused. * src/ls.c (dev_ino_push): New function, replacing ... (DEV_INO_PUSH): ... this removed macro. All uses changed. (decode_switches): Rewrite "str"+i to &str[i].
2013-05-11build: update gnulib submodule to latestPaul Eggert
2013-01-01maint: update all copyright year number rangesJim Meyering
Run "make update-copyright", but then also run this, perl -pi -e 's/2\d\d\d-//' tests/sample-test to make that one script use the single most recent year number.
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.
2012-09-14build: don't prefix the RHS of "GPERF = ..." with "lib/"Jim Meyering
* gl/build-aux/prefix-gnulib-mk (prefix_assignment): Exempt the RHS of a "GPERF = ..." assignment from lib/ prefixing.
2012-09-12maint: mbsalign.h: fix typo from previous comment editBernhard Voelker
* gl/lib/mbsalign.h: Fix comment typo.
2012-09-11build: handle @ALLOCA@-vs-non-recursive make problemsJim Meyering
Here is a good reason to avoid alloca with non-recursive make. These: $ grep @ALLOCA lib/gnulib.mk lib_libcoreutils_a_LIBADD += lib/@ALLOCA@ lib_libcoreutils_a_DEPENDENCIES += lib/@ALLOCA@ would lead to this, when @ALLOCA@ expands to the empty string, which is essentially "always", now: $ grep ' lib/$' Makefile lib_libcoreutils_a_LIBADD = $(gl_LIBOBJS) lib/ lib_libcoreutils_a_DEPENDENCIES = $(gl_LIBOBJS) lib/ Tell the prefix-adding script not to add a prefix when the word it's prefixing is "@ALLOCA@". That is fine for most cases, but what about when the expansion of @ALLOCA@ is nonempty? * build-aux/prefix-gnulib-mk (prefix_word): Exclude @ALLOCA@. * gl/m4/non-recursive-gnulib-prefix-hack.m4: Prefix non-empty $ALLOCA with "lib/". FIXME: I'm not sure this is required, now that we... Use AC_CONFIG_LIBOBJ_DIR([lib]). Without using AC_CONFIG_LIBOBJ_DIR([lib]), automake (not autoconf) would complain of failure to find aclocal.c, due to the use of AC_LIBSOURCES(alloca.c).
2012-09-11build: new module to convert lib/ to non-recursive makeJim Meyering
* gl/modules/non-recursive-gnulib-prefix-hack: New module. * gl/m4/non-recursive-gnulib-prefix-hack.m4: (gl_NON_RECURSIVE_GNULIB_PREFIX_HACK): This is the snippet that this module inserts near the end of configure. * gl/build-aux/prefix-gnulib-mk: New script, from bison. Changes from the code in bison: (prefix_assignment): Split a long line. (prefix): Add trailing slashes to avoid a single false match. Prefix imaxtostr.c and the other *tostr.c file names manually. Also, use $prefix in place of hard-coded "lib/".
2012-09-11maint: add more control flags to mbsalignPádraig Brady
* gl/lib/mbsalign.h: Add MBA_UNIBYTE_ONLY (to allow faster processing). Also add MBA_NO_LEFT_PAD, MBA_NO_RIGHT_PAD to give greater control of padding, useful with the first or last fields on a line. * gl/lib/mbsalign.c (mbsalign): Implement the new flags. * gl/tests/test-mbsalign.c (main): Test combinations of the new flags.
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.
2012-07-27maint: refresh stale local gnulib patch filesJim Meyering
We carry local adjustments for a few gnulib modules via the patches in gl/. Nearly all of those patches had become stale due to evolution of the originals in gnulib. To refresh them, first make sure you have no local changes in gl/ or in the gnulib submodule, then run "make refresh-gnulib-patches".
2012-06-10build: update gnulib to latest; correct comment grammarJim Meyering
* tests/misc/help-version: Fix comment grammar: s/all these/all of these/ * gl/lib/tempname.c.diff: Likewise.
2012-02-12build: correct @@-,length values in last hunk of regcomp.c.diffJim Meyering
* gl/lib/regcomp.c.diff: Correct invalid hunk lengths (s/1/7/g) in the last hunk's @@-line.
2012-02-12build: update gnulib, bootstrap, gl/lib/regcomp.c.diffJim Meyering
* gnulib: Update submodule to latest. * bootstrap: Update from gnulib. * gl/lib/regcomp.c.diff: Adapt to gnulib changes.
2012-01-27maint: use single copyright year rangeJim Meyering
Run "make update-copyright".
2012-01-09maint: straggler *.[ch] files: convert more `...' to '...'Jim Meyering
The preceding commands ignored .[ch] files in lib/ and gl/. This is what I should have been doing from the start: git grep -l '`.*'\' $(g ls-files |grep '\.[ch]$') \ | xargs perl -pi -e 's/`(.+?'\'')/'\''$1/'
2012-01-01maint: update all copyright year number rangesJim Meyering
Run "make update-copyright".
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.
2011-10-30maint: avoid new "make syntax-check" failure due to stdalign definitionJim Meyering
* gl/modules/randread (Depends-on): Add stdalign. * gl/lib/randread.c: Include <stdalign.h>, so we can ... [!_STRING_ARCH_unaligned]: remove definition of stdalign.
2011-10-27build: avoid bootstrap failure when using patch-2.5.8Jim Meyering
* gl/modules/tempname.diff: Regenerate to correct bogus offsets and adjust for 1-line offset. Eric Blake reported that this patch failed to apply when using patch-2.5.8. Note that it applies fine using patch-2.6.1.
2011-09-17randread: add FIXME comment for RDRANDPaul Eggert
* gl/lib/randread.c: Add a FIXME comment suggesting how to improve performance by using the RDRAND hardware instruction.
2011-08-30build: heap.c: make possible gnulib candidate c89 compatiblePádraig Brady
* gl/lib/heap.c: Move declaration to the top of scope. Reported by Rob McMahon and Wolfgang Steinwender in relation to "Sun WorkShop 6 update 2 C 5.3 Patch 111679-12 2003/05/18" and "GCC 2.95.3" respectively.
2011-08-08mktemp: stir in enough entropy (Bug#6683)Paul Eggert
* gl/lib/tempname.c.diff (gen_tempname_len): Use x_suffix_len bytes' worth of entropy, not 8 bytes.
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.

2011-06-17maint: use modules/tempname.diff file, not a replacement; update gnulibJim Meyering
Using a .diff is much more maintainable. Otherwise, changes in the gnulib module description file may not be noticed and merged promptly and may even result in subtle errors. Luckily, this time, the failure to propagate gnulib's changes to modules/tempname resulted only in an obvious link failure. * gl/modules/tempname: Remove file. * gl/modules/tempname.diff: Use a .diff file instead. * gnulib: Update submodule to latest.
2011-05-29maint: remove unnecessary gnulib .diff fileJim Meyering
* gl/modules/getloadavg.diff: Remove file. It stopped being useful back in February. * Makefile.am (EXTRA_DIST): Remove it.
2011-05-26maint: enforce cpp indentation policyJim Meyering
* cfg.mk (sc_preprocessor_indentation): New test, from libvirt. Exempt 3 files from new cppi test. * gl/lib/randread.c: Adjust cpp indentation to comply. * src/extent-scan.c (extent_need_sync): Likewise.
2011-05-14shuf: use memory more efficiently when returning a subsetPádraig Brady
* gl/lib/randperm.c (randperm_new): When the number of items to return H, is much smaller than the total number of items N, use a hash to represent the sparse permutations of the set N. This is currently enabled for N > 128K and N/H > 32. * tests/misc/shuf: Ensure shuf can quickly return 2 numbers from a large range. * gl/modules/randperm: Depend on hash. * NEWS: Mention the change.
2011-04-11maint: remove doubled words in comments, e.g., s/to to/to/Jim Meyering
* tests/ls/color-norm: s/to to/to/ * gl/lib/mbsalign.h (mbs_align_t): s/or or/or/ * src/extent-scan.c (extent_scan_read): s/the the/the/ * src/libstdbuf.c: s/the the/the/ * tests/misc/stdbuf: s/on on/on/ * ChangeLog-2005: s/for\n\tfor /for\n\t/
2011-03-13maint: use wcswidth from gnulibPádraig Brady
* gl/lib/mbsalign.c (rpl_wcswidth): Remove this in favor of the equivalent wcswidth replacement in gnulib. * bootstrap.conf: Depend on the wcswidth module. Suggested by Bruno Haible.
2011-02-08tests: randread-tests: use macro.h not "#define ASSERT..."Jim Meyering
* gl/modules/randread-tests (Files): Add tests/macros.h * gl/tests/test-rand-isaac.c: Remove now-unneeded #include directives. (ASSERT): Remove definition. Instead, include "macros.h". Prompted by suggestions from Bruno Haible.
2011-02-07maint: move di-set and ino-map modules from ./gl to gnulibJim Meyering
* gl/lib/di-set.c: Remove file. * gl/lib/di-set.h: Likewise. * gl/lib/ino-map.c: Likewise. * gl/lib/ino-map.h: Likewise. * gl/modules/di-set: Likewise. * gl/modules/di-set-tests: Likewise. * gl/modules/ino-map: Likewise. * gl/modules/ino-map-tests: Likewise. * gl/tests/test-di-set.c: Likewise. * gl/tests/test-ino-map.c: Likewise. * gnulib: Update to latest, now that these two modules are there.
2011-02-07di-set: provide a lookup methodJim Meyering
This is required for patch, and hence is about to move to gnulib. * gl/lib/di-set.c (di_set_lookup): New function. * gl/lib/di-set.h: Declare it. * gl/tests/test-di-set.c (main): Exercise it. The bug was introduced on 2004-12-04 via commit 7380cf79.
