2011-09-19md5sum: clarify what is meant by binary/text flag.Reuben Thomas
src/md5sum.c: Clarify that we are talking about input mode. doc/coreutils.texi: Ditto.
2011-07-31doc: mention the new mirroring behavior of cp -auPádraig Brady
* NEWS: Mention the change in behavior. * doc/coreutils.texi (cp invocation): Likewise.
2011-07-25timeout: support sub-second timeoutsPádraig Brady
* src/timeout.c (settimeout): A new function to convert from a floating point duration and call alarm() or timer_settime() if that's available. (parse_duration): Return a double rather than unsigned int. (usage): Mention floating point is supported. (main): Pass the double to settimeout() rather than calling alarm() directly with the parsed int. (cleanup): Likewise. * doc/coreutils.texi (timeout invocation): Say floating point timeouts now supported, and mention the caveat with resolution. * bootstrap.conf: Include the timer-time gnulib module. * tests/misc/timeout-parameters: Add a test with nanoseconds. * NEWS: Mention the improvement.
2011-07-08timeout: add --foreground to support interactive commandsPádraig Brady
Or more accurately, commands not started from the shell prompt, that are interactive, or need to receive Ctrl-C etc. from the terminal. * doc/coreutils.texi (timeout invocation): Document --foreground. * src/timeout.c (main): Set the foreground flag and don't create a separate group. (cleanup): Only send a signal directly to the monitored command when the foreground flag is set. (usage): Describe --foreground. * tests/misc/timeout-group: Add a new test. * tests/Makefile.am: Reference new test. NEWS: Mention the new option. Reported by Shay Shimony Analysis by Alan Curry Fix suggested by Paul Eggert
2011-07-07md5sum, sha1sum, etc: accept new option: --strictPatrick Schoenfeld
Use this new option with --check when the input is expected to consist solely of checksum lines. With only --check, an invalid line evokes a warning, but the program can still exit successfully. With --strict, any invalid line makes the program exit non-zero. * src/md5sum.c (strict, STRICT_OPTION): Declare/define. (long_options): Add "strict". (usage): Describe --strict. (digest_check): Count improperly_formatted lines, too, and use that number and the global "strict" to determine the return value. (main): Handle STRICT_OPTION. Reject --strict without --check. * doc/coreutils.texi: Describe it. * NEWS (New features): Mention it.
2011-07-07doc: note date's %k, %l are space-padded and equivalent to %_H and %_IBenoît Knecht
* src/date.c (usage): As above, for --help. * doc/coreutils.texi (Time conversion specifiers): Likewise. Reported by Britton Leo Kerin in http://bugs.debian.org/115833.
2011-07-01doc: detail the effect of disabling input buffering with stdbufPádraig Brady
* docs/coreutils.texi (stdbuf invocation): Expand on the different reasons for disabling buffering on input and output.
2011-07-01doc: mention the restrictions for stdbuf more prominentlyBruno Haible
* doc/coreutils.texi (stdbuf invocation): List the contraints on the command being controlled, up front.
2011-05-31* doc/coreutils.texi (sort invocation): I/0 -> I/O (sr#107504)Paul Eggert
2011-05-24doc: improve tail -f vs. inotify description and advicePádraig Brady
* doc/coreutils.texi (tail invocation): Adjust, and add an example.
2011-05-23maint: avoid trivial syntax-check failureJim Meyering
* doc/coreutils.texi (tail invocation): Use @var{n}, not @var{N}.
2011-05-23doc: describe how kernel inotify support affects tail -fJim Meyering
* doc/coreutils.texi (tail invocation) [-f]: Mention how inotify kernel support makes a difference. Prompted by http://bugzilla.redhat.com/662900
2011-05-22doc: fix a formatting nit in od's texinfo documentationJim Meyering
* doc/coreutils.texi (od invocation): Typesetting of "bytes" was wrong. Fix it via s/@code/@var/ so it's consistent.
2011-05-13ls: allow stat-free use of --colorJim Meyering
Even on a system with d_type support, the default use of --color makes ls stat every file in order to be able to honor settings like EXEC, STICKY, ORPHAN, SETUID, etc., because those settings require information that is not provided by dirent.d_type. However, if for a potentially large performance gain, you are willing to disable those settings, you can now make ls --color give type-related coloring and perform no stat calls at all (other than the unavoidable call-per- command-line argument). Before this change, even with all of those attributes disabled, ls --color would still stat every directory. Now, we're down to the minimum of one stat call per command-line arg. * src/ls.c (gobble_file): With --color, don't stat a non-command-line-specified directory when no directory-coloring attribute is enabled. * tests/init.cfg (require_dirent_d_type_): New function. * tests/d_type-check: New script, mostly from Pádraig Brady. * tests/Makefile.am (EXTRA_DIST): Add it. * tests/ls/stat-free-color: New test. * tests/Makefile.am (TESTS): Add it. * doc/coreutils.texi (General output formatting): Describe how to use dircolors to make ls --color refrain from calling stat on a d_type-enabled file system. Prompted by a query from Josef Bacik.
2011-05-06doc: document split's new --filter=CMD optionJim Meyering
* doc/coreutils.texi (split invocation): Describe --filter=CMD. * NEWS (New feature): Mention it.
2011-04-25doc: tail/inotify does use --sleep-interval=S, with --pid=PJim Meyering
* doc/coreutils.texi (tail invocation): Mention it. * src/tail.c (usage): Likewise. (tail_forever_inotify): Clarify comment.
2011-04-11maint: misc typo fixesPádraig Brady
* src/fiemap.h: s/can not/cannot/ * NEWS: s/in/is/ * doc/coreutils.texi: Remove spurious "and". s/effect/affect/ Use matched ``...'' quotes.
2011-04-04docs: mention POSIX 2008Eric Blake
* doc/coreutils.texi (Standards conformance): Give value of _POSIX2_VERSION matching the _POSIX_C_SOURCE of POSIX 2008.
2011-03-22test: accept "==" as a synonym for "="David A. Wheeler
Make GNU coreutils' test recognize "==" as a synonym for "=". This is already the case in GNU coreutils' expr, bash, ksh, busybox ash, FreeBSD-current /bin/sh and /bin/test, and OpenBSD's /bin/sh. Before, env test a '==' a would fail with this diagnostic: "test: ==: binary operator expected". Now, it succeeds. * src/test.c: Accept "==" as a synonym for "=". * doc/coreutils.texi (String tests): Document it. Reported as http://debbugs.gnu.org/8263 Also see http://austingroupbugs.net/view.php?id=375
2011-03-05dd: add a flag to discard cached dataPádraig Brady
* src/dd.c (FFS_MASK): A new macro (Find First Set) refactored from the following enum as it's now used twice. (usage): Mention the new 'nocache' flag. (cache_round): A new function to help ignore requests to drop cache, that are less than page_size. (invalidate_cache): A new function to call posix_fadvise() with the appropriate offset and length. Note we don't use fdadvise() so we can detect errors when count=0. (dd_copy): Call invalidate_cache() for the portions read. (iwrite): Likewise for the portions written. (main): Call invalidate_cache for page_size slop or for full file when count=0. * cfg.mk (sc_dd_O_FLAGS): Adjust to pass. * doc/coreutils.texi (dd invocation): Describe the 'nocache' flag, and give some examples of how it can be used. * tests/dd/nocache: A new test. * tests/Makefile.am: Reference the new test. * NEWS: Mention the new feature.
2011-03-05doc: clarify that `dd bs=` can immediately output short readsPádraig Brady
* doc/coreutils.texi (dd invocation): Clarify that bs= can cause parital reads to be immediately written to output. * src/dd.c (usage): Hint that bs= can cause partial writes. See http://debbugs.gnu.org/cgi/bugreport.cgi?bug=8171
2011-03-05doc: group dd conv= options that are actually flagsPádraig Brady
* src/dd.c (usage): Move 'sync' up with other data transformation options. Having it alongside 'fsync' and 'fdatasync' is particularly confusing. Also the double line description of the 'sync' option, serves as a visual break from the "flag" type options that follow. * doc/coreutils.texi (dd invocation): Apply the same grouping as above, by splitting the "conv=" table in two.
2011-01-29doc: add alternatives for field processing not supported by cutPádraig Brady
* doc/coreutils.texi (cut invocation): Remove the tr -s '[:blank:]' example, as it doesn't handle leading and trailing blanks. Add `awk` examples for common field processing operations often asked about. Also document a `join` hack, to achieve the same thing. Note the join options are ordered so as to be compatible with other systems.
2011-01-29join: don't report disorder against an empty filePádraig Brady
This allows one to use join as a field extractor like: join -a1 -o 1.3,1.1 - /dev/null * src/join.c (join): Don't flag unpairable lines when one of the files is empty. * tests/misc/join: Add a new test for empty input, and adjust a previous test that was only checking against empty input. * doc/coreutils.texi (join invocation): Document the change. * NEWS: Likewise.
2011-01-29join: add -o 'auto' to output a constant number of fields per linePádraig Brady
Lines with a different number of fields than the first line, will be truncated or padded. * src/join.c (prfields): A new function refactored from prjoin(), to output all but the join field. (prjoin): Don't swap line1 and line2 when line1 is blank so that the padding is applied to the right place. (main): Handle the -o 'auto' option. * tests/misc/join: Add 6 new cases to test the auto format. * NEWS: Mention the change in behavior. Suggestion from Assaf Gordon
2011-01-21doc: fix wording in warning about potential conflict with built-inJim Meyering
* doc/coreutils.texi (mayConflictWithShellBuiltIn): Fix wording.
2011-01-21manual: document floating point betterPaul Eggert
* doc/coreutils.texi (Floating point): New section. (od invocation, tail invocation, sort invocation, printf invocation): (sleep invocation, seq invocation): Refer and defer to it. See <http://lists.gnu.org/archive/html/bug-coreutils/2011-01/msg00031.html>.
2011-01-17doc: show how to shred more efficientlyJim Meyering
* doc/coreutils.texi (shred invocation): Give an example showing how to invoke shred in single-pass mode, and warn that -n0 --zero may be inadequate.
2011-01-15doc: specify how tr, echo, printf treat octal numbersOndřej Vašík
* doc/coreutils.texi (tr's Character sets): Document how a 9-bit octal value is interpreted. tr does not ignore the ninth bit. (echo invocation, printf invocation): Document that any ninth bit in \OOO is ignored. (http://debbugs.gnu.org/7574)
2011-01-01maint: update all copyright year number rangesJim Meyering
Run "make update-copyright".
2010-12-28coreutils: keep lines within 80-column limitsPaul Eggert
* cfg.mk (LINE_LEN_MAX, FILTER_LONG_LINES): New macros. (sc_long_lines): New rule. * HACKING: Use shorter URLs to the same material. * doc/Makefile.am, doc/coreutils.texi, m4/boottime.m4: * man/help2man, man/stdbuf.x, src/Makefile.am, src/cat.c, src/copy.c: * src/cp.c, src/dd.c, src/df.c, src/du.c, src/groups.c, src/install.c: * src/ls.c, src/md5sum.c, src/mv.c, src/od.c, src/pinky.c, src/ptx.c: * src/readlink.c, src/remove.c, src/rmdir.c, src/setuidgid.c: * src/sort.c, src/tail.c, src/touch.c, tests/Coreutils.pm: * tests/cp/existing-perm-race, tests/cp/perm, tests/cp/preserve-gid: * tests/du/2g, tests/du/long-from-unreadable, tests/init.sh: * tests/install/basic-1, tests/ls/nameless-uid: * tests/ls/readdir-mountpoint-inode, tests/misc/chroot-credentials: * tests/misc/cut, tests/misc/date, tests/misc/join, tests/misc/md5sum: * tests/misc/sha1sum, tests/misc/sha224sum, tests/misc/sort: * tests/misc/sort-continue, tests/misc/sort-files0-from: * tests/misc/sort-rand, tests/misc/stdbuf, tests/misc/tr: * tests/misc/uniq, tests/mv/atomic, tests/mv/part-fail: * tests/mv/part-symlink, tests/mv/sticky-to-xpart, tests/pr/pr-tests: * tests/rm/fail-2eperm, tests/rm/interactive-always: Reformat to fit within 80 columns. * doc/Makefile.am (BAD_POSIX_PERL): New macro. * doc/coreutils.texi: Reword slightly, to make menus and index lines shorter. * src/md5sum.c: Redo --help output so that it fits within 79 columns, since that's a bit more portable and all the other --help strings fit in 79 columns.
2010-12-19sort: use at most 8 threads by defaultPádraig Brady
* src/sort.c (main): If --parallel isn't specified, restrict the number of threads to 8 by default. If the --parallel option is specified, then allow any number of threads to be set, independent of the number of processors on the system. * doc/coreutils.texi (sort invocation): Document the changes to determining the number of threads to use. Mention the memory overhead when using multiple threads. * tests/misc/sort-spinlock-abuse: Allow single core systems that support pthreads. * tests/misc/sort-stale-thread-mem: Likewise. * tests/misc/sort-unique-segv: Likewise. * NEWS: Mention the change in behaviour.
2010-12-18doc: split: add examples showing how to use the new optionJim Meyering
* doc/coreutils.texi (split invocation): Add examples.
2010-12-14doc: tail: semi-deprecate --sleep-interval and --max-unchanged-statsJim Meyering
Those options are useful only on systems that lack inotify support and in the unusual event that a system with inotify support must resort to polling. * src/tail.c (usage): Note that the --max-unchanged-stats=N and --sleep-interval=N options are rarely useful on systems with inotify support. * doc/coreutils.texi (tail invocation): Likewise.
2010-11-22split: add --number to generate a particular number of filesChen Guo
* src/split.c (usage, long_options, main): New options --number, --unbuffered, --elide-empty-files. (set_suffix_length): New function to auto increase suffix length to handle a specified number of files. (create): New function. Refactored from cwrite() and ofile_open(). (bytes_split): Add max_files argument to support byte chunking. (lines_chunk_split): New function. Split file into chunks of lines. (bytes_chunk_extract): New function. Extract a chunk of file. (of_info): New struct. Used by functions lines_rr and ofile_open to keep track of file descriptors associated with output files. (ofile_open): New function. Shuffle file descriptors when there are more output files than available file descriptors. (lines_rr): New function to distribute lines round-robin to files. (chunk_parse): New function. Parses K/N syntax. * tests/misc/split-bchunk: New test for byte chunking. * tests/misc/split-lchunk: New test for line delimited chunking. * tests/misc/split-rchunk: New test for round-robin chunking. * tests/Makefile.am: Reference new tests. * tests/misc/split-fail: Add failure scenarios for new options. * tests/misc/split-l: Fix a typo. s/ln/split/. * doc/coreutils.texi (split invocation): Document --number. * NEWS: Mention the new feature. * .mailmap: Map new email address for shortlog. Signed-off-by: Pádraig Brady <P@draigBrady.com>
2010-11-13doc: tweak NEWS and coreutils.texiPaul Eggert
* doc/coreutils.texi (stat invocation): Add sentence-ending period. * NEWS: Correct stat change description: s/floating point //. * cfg.mk (old_NEWS_hash): Update, to match this NEWS change.
2010-11-13stat: do not provide variable precision time stampsJim Meyering
* src/stat.c: Don't include fstimeprec.c. (out_epoch_sec): Don't call fstimeprec. * NEWS: Update description. * doc/coreutils.texi: Likewise.
2010-11-11csplit: do not rely on undefined behavior in printf formatsPaul Eggert
* doc/coreutils.texi (csplit invocation): Say that %d and %i are aliases for %u. * src/csplit.c (FLAG_THOUSANDS, FLAG_ALTERNATIVE): New constants. (get_format_flags): Now take char const * and int * and return size_t. It now stores info about the flags instead of merely scanning them. Also, it handles '0' correctly. Drop support for the undocumented '+' and ' ' flags since the value is unsigned. Add support for the (undocumented) "'" flag. All uses changed. (get_format_width, get_format_prec): Remove. (check_format_conv_type): Renamed from get_format_conv_type, with a different signature. It now converts the format to one that is compatible with unsigned int, and checks flags. All uses changed. (max_out): Have snprintf compute the number of bytes needed rather than attempting to do it ourselves (which doesn't work portably with outlandish formats such as %4294967296d). (check_format_conv_type, main): Check for overflow in size calculations. Don't assume size_t fits in unsigned int. * tests/misc/csplit: Check for proper handling of flags, with %0#6.3x. Coreutils 8.6 mishandles this somewhat-weird example.
2010-11-06stat: use e.g. %.3X instead of %X.%3:X for sub-second precisionPaul Eggert
* NEWS: Document this. * doc/coreutils.texi (stat invocation): Likewise. * gl/lib/fstimeprec.c, gl/lib/fstimeprec.h, gl/modules/fstimeprec: * gl/modules/fstimeprec-tests, gl/tests/test-fstimeprec.c: New files. * bootstrap.conf (gnulib_modules): Add fstimeprec. * src/stat.c: Include fstimeprec.h. Don't include xstrtol.h. (decimal_point, decimal_point_len): New static vars. (main): Initialize them. (epoch_sec, out_ns): Remove. (out_int, out_uint): Now returns whatever printf returned. (out_minus_zero, out_epoch_secs): New functions. (print_stat): Use out_epoch_sec instead of out_ns and epoch_sec. (print_stat, print_it, usage): Remove the %:X-style formats. * tests/misc/stat-nanoseconds: Set TZ=UTC0 to avoid problems with weird time zones. Use a time stamp near the Epoch so that we don't have to worry about leap seconds. Redo test cases to match new behavior. * tests/touch/60-seconds: Change %Y.%:Y to %.9Y, to adjust to new behavior.
2010-11-03stat: revert %X-%Y-%Z change; use e.g., %:X to print fractional secondsJim Meyering
This reverts part of the recent commit 9069af45, "stat: print timestamps to full resolution", which made %X, %Y, %Z print floating point numbers. We prefer to retain portability of %X, %Y and %Z uses, while still providing access to full-resolution time stamps via modified format strings. Also make the new %W consistent. * src/stat.c: Include "xstrtol.h". (print_it): Accept a new %...:[XYZ] format directive, e.g., %:X, to print the nanoseconds portion of the corresponding time. For example, %3.3:Y prints the zero-padded, truncated, milliseconds part of the time of last modification. (print_it): Update print_func signature to match. (neg_to_zero): New helper function. (epoch_time): Remove function; replace with... (epoch_sec): New function; use timetostr. (out_ns): New function. Use "09" only when no other modifier is specified. (print_statfs): Change type of "m" to unsigned int, now that it must accommodate values larger than 255. (print_stat): Likewise. Map :X to a code of 'X' + 256. Likewise for Y, Z and W. (usage): Update. * tests/touch/60-seconds: Use %Y.%:Y in place of %Y. * tests/misc/stat-nanoseconds: New file. * tests/Makefile.am (TESTS): Add it. * NEWS (Changes in behavior): Mention this. With improvements by Pádraig Brady. Thanks to Andreas Schwab for raising the issue.
2010-10-27cp: make --attributes-only override --reflink completelyPádraig Brady
* doc/coreutils.texi (cp invocation): Change the description slightly so as users might not immediately discount using this option. Mention that --reflink is overridden by the other linking options and --attributes-only, and give an example where this might be useful. * src/copy.c (copy_internal): Bypass the reflink if --attributes-only is specifed. * tests/cp/reflink-perm: Ensure both --reflink modes are overridden by --attributes-only. * NEWS: Mention the change in behavior. Reported by Jim Meyering.
2010-10-05build: complete the rename of get_dateEric Blake
* gnulib: Update to latest. * src/date.c (includes, batch_convert, main): Track rename. * src/touch.c (includes, get_reldate): Likewise. * doc/coreutils.texi (Top, Date input formats): Likewise. * bootstrap.conf (gnulib_modules): Likewise. * doc/Makefile.am (EXTRA_DIST): Likewise. * doc/.gitignore: Likewise. * bootstrap: Synchronize from upstream.
2010-10-05stat: drop %C support when printing file system detailsEric Blake
* src/stat.c (print_statfs, usage): Drop %C, since it applies to files, not file systems. (out_file_context): Match style of other out_* functions. (print_stat): Update caller. * doc/coreutils.texi (stat invocation): Document %C. * NEWS: Document the change.
2010-10-01stat: support printing birthtimeEric Blake
* src/stat.c (print_stat): New %w and %W formats. (do_stat): Include %w in default format. (usage): Document new specifiers. * doc/coreutils.texi (stat invocation): Likewise. * NEWS: Likewise.

* gnulib: Update to latest. * doc/coreutils.texi (date): Reflect new module name. * doc/Makefile.am (EXTRA_DIST): Likewise. * doc/.gitignore: Likewise.
2010-09-20tests: fix an erroneous stat failure with bind mountsPádraig Brady
* tests/misc/stat-mount: Don't try to correlate the mount points output by df and stat, as they're similar, but sometimes different in the presence of bind mounts. * doc/coretuils.texi (stat invocation): Clarify the bind mount difference between stat and df.
2010-08-27doc: clarify that stat -f implies -L (follows symlinks)Pádraig Brady
* doc/coreutils.texi (stat invocation). Since there is no lstatfs, document that -L is implicit with -f.
2010-08-27stat: add %m to output the mount point for a fileAaron Burgemeister
* src/find-mount-point.c: A new file refactoring find_mount_point() out from df.c * src/find-mount-point.h: Likewise. * src/df.c: Use the new find-mount-point module. * src/stat.c (print_stat): Handle the new %m format. (find_bind_mount): A new function to return the bind mount for a file if any. (out_mount_mount): Print the bind mount for a file, or else the standard mount point given by the find-mount-point module. (usage): Document the %m format directive. * src/Makefile.am: Reference the refactored find-mount-point.c * po/POTFILES.in: Add find_mount_point.c to the translation list * doc/coreutils.texi (stat invocation): Document %m, and how it may differ from the mount point that df outputs. * test/misc/stat-mount: A new test to correlate mount points output from df and stat. * tests/Makefile.am: Reference the new test. * NEWS: Mention the new feature * THANKS: Add the author Signed-off-by: Pádraig Brady <P@draigBrady.com>
2010-08-15doc: avoid a warning from newer texinfoRalf Wildenhues
