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.

(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
* doc/coreutils.texi (sort invocation): Use @pxref inside parentheses.
2010-08-15doc: improve the info on md5sum security weaknessesBruno Haible
* doc/coreutils.texi (md5sum invocation): Mention currently known security problems. Don't recommend SHA-1 as alternative. * man/md5sum.x (BUGS): Warn about the vulnerabilities and reference the SHA-2 based alternatives. Reported by Simon Josefsson
2010-08-02sort: revert recent -h changes and use a more-conservative approachPaul Eggert
* NEWS: Document changes to sort -h, which are now minor with respect to the pre-July-30th version. * doc/coreutils.texi (sort invocation): Likewise. The documentation now describes how -h comparison is done rather than being vague with border cases. * src/sort.c (long_double, strtold): Move back to general_numcompare. (LD, compute_human): Remove. (find_unit_order): Remove THOU_SEP parameter, since thousands separators are now allowed by all callers. Revert to previous behavior of sorting by suffix, and returning the order rather than 2 * order + binary, since we no longer care whether binary powers are being used. However, treat all zeros the same, instead of sorting 0M before 0G; this is more consistent with the desired behavior of sorting -1G before -1M. * tests/misc/sort (h1, h3, h6): Adjust to match mostly-reverted behavior. However, check that all zeros sort together. * tests/misc/sort-debug-keys: Omit a "_", since the trailing "i" in "1234Gi" is no longer part of the key.
2010-07-30sort: -h now handles comparisons such as 6000K vs 5M and 5MiB vs 5MBPaul Eggert
* NEWS: Document changes to sort -h. * doc/coreutils.texi (sort invocation): Likewise. * src/sort.c (long_double, strtold): Move to prelude, since they're now used by multiple functions. (LD): New macro. (struct keyfield.iec_present): Remove this member. All uses removed. (check_mixed_SI_IEC): Remove. This code was busted in the presence of multiple threads, as it had a race condition. (find_unit_order): Remove arg KEY; add arg THOU_SEP; arg ENDPTR is now char ** rather than char const **. Return an integer that distinguishes decimal from binary powers. Parse the number consistently with the intersection of strtold and strnumcmp. Set *ENDPTR unconditionally. (compute_human): New static function. (human_numcompare): Remove arg KEY. Remove 'const' from other args. Use strnumcmp if possible, but fall back on floating point if not. (numcompare, general_numcompare): Arg EA is now char ** rather than char const **. (numcompare): Adjust to new find_unit_order signature and behavior. (keycompare): Adjus to new human_numcompare signature. * tests/misc/sort (h1, h3, h4, h6): Adjust to new behavior. * tests/misc/sort-debug-keys: Likewise.
2010-07-13sort: parallelize internal sortChen Guo
This patch is by Gene Auyeung, Chris Dickens, Chen Guo, and Mike Nichols, based off of a patch by Paul Eggert, Glen Lenker, et. al., with a basic heap implementation based off of the GDSL heap, originally by Nicolas Darnis. The number of sorts done in parallel is limited to the number of available processors by default, or can be further restricted with the --parallel option. On a dual-die, 8 core Intel Xeon, results show sorting with 8 threads is almost 4 times faster than using a single thread. Timings when sorting a 96MB file: THREADS TIME (s) 1 5.10 2 2.87 4 1.75 8 1.31 Single threaded sorting has also been improved, especially for cheaper comparison operations: COMMAND BEFORE (s) AFTER (s) sort 8.822 8.716 sort -g 10.336 10.222 sort -n 3.077 2.961 LANG=C sort 2.169 2.066 * bootstrap.conf: Add heap, pthread. * coreutils.texi (sort): Describe the new --parallel option. * gl/lib/heap.c: New file. Very basic heap implementation. * gl/lib/heap.h: New file. * gl/modules/heap: New file. * src/Makefile.am: Add LIB_PTHREAD. * src/sort.c: Include heap.h, nproc.h, pthread.h. (MAX_MERGE): New macro. (SUBTHREAD_LINES_HEURISTIC, PARALLEL_OPTION): New constants. (MERGE_END, MERGE_ROOT): New constants. (struct merge_node): New struct. (struct merge_node_queue): New struct. (sortlines temp): Remove declaration. (usage, long_options, main): New option, --parallel. (specify_nthreads): New function. (mergelines): New signature, to emphasize the fact that the HI area must be part of the destination. All callers changed. (sequential_sort): New function, renamed from sortlines. Merge in the functionality of sortlines_temp. (compare_nodes): New function. (lock_node, unlock_node): New functions. (queue_destroy): New function. (queue_init): New function. (queue_insert): New function. (queue_pop): New function. (write_unique): New function. (mergelines_node): New function. (check_insert): New function. (update_parent): New function. (merge_loop): New function. (sortlines): Rewrite to support and use parallelism, with a new signature. All callers changed. (struct thread_args): New struct. (sortlines_thread): New function. (sortlines_temp): Remove. (sort): New argument NTHREADS. All uses changed. Output moved to mergelines_node. (main): disable threading if we are sorting at random. * tests/Makefile.am (TESTS): Add misc/sort-benchmark-random. * tests/misc/sort-benchmark-random: New file. Signed-off-by: Pádraig Brady <P@draigBrady.com>
2010-07-01cp: add an option to only copy the file attributesPádraig Brady
* src/copy.c (copy_attr): A new function which merges copy_attr_by_fd and copy_attr_by_name. Also display all errors when --attributes-only * src/copy.c (copy_reg): Skip copying the file contents if specified. Refactor the SELinux error handling code a little and display all SELinux errors when only copying attributes. * src/copy.h (struct cp_options): Add a data_copy_required boolean * src/cp.c (main): Default to copying data but don't if specified * src/install.c: Default to copying data * src/mv.c: Likewise tests/cp/reflink-perm: Add a test to check that --attributes-only does not copy data * tests/cp/acl: Likewise. Also refactor to remove redundant acl manipulation * doc/coreutils.texi (cp invocation): Describe the new option * NEWS: Mention the new feature
2010-07-01ls: use the POSIX date style when the locale does not specify onePádraig Brady
Previously we defaulted to "long-iso" format in locales without specific format translations, like the en_* locales for example. This reverts part of commit 6837183d, 08-11-2005, "ls ... acts like --time-style='posix-long-iso' if the locale settings are messed up" * src/ls.c (decode_switches): Only use the ISO format when specified. * NEWS: Mention the change in behavior. Reported by Daniel Qarras at http://bugzilla.redhat.com/525134
2010-06-14cat: improve documentationEric Blake
* src/cat.c (usage): Clarify that -b overrides -n. * doc/coreutils.texi (cat invocation): Likewise. * THANKS: Update. Suggested by Chas. Owens, in bug 6383.
2010-06-14doc: dd: discourage use of very large block sizesJim Meyering
* doc/coreutils.texi (dd invocation): Warn against using a very large block size. Suggested by Imre Péntek.
2010-06-08dirname: tweak summary wordingEric Blake
* doc/coreutils.texi (dirname invocation): Reword to be more precise. * src/dirname.c (usage): Likewise. * THANKS: Update. Reported by Filipus Klutiero, bug 6175.
2010-05-28truncate: support sizes relative to an existing filePádraig Brady
* doc/coreutils.texi (truncate invocation): Mention that --reference bases the --size rather than just setting it. * src/truncate.c (usage): Likewise. Also remove the clause describing --size and --reference as being mutually exclusive. (do_truncate): Add an extra parameter to hold the size of a referenced file, and use it if positive. (main): Pass the size of a referenced file to do_truncate(). * tests/misc/truncate-parameters: Adjust for the new combinations. * NEWS: Mention the change Suggested by Richard W.M. Jones
2010-05-19du: recognize -d N as equivalent to --max-depth=NJon Ringuette
* NEWS (New features): Mention it. * src/du.c (DEBUG_OPT): Remove. Use long-named ---debug instead. Commented out. (MAX_DEPTH_OPTION): Remove. Use 'd' instead. (main): Insert literal "d:"; remove DEBUG_OPT. * doc/coreutils.texi (du invocation): Add -d to indices. * tests/du/max-depth: Exercise -d, too.
2010-05-16doc: fix sort info about version sort skipping blanksPádraig Brady
* doc/coreutils.text (sort invocation): leading blanks are significant for 'V'.
2010-05-16sort: --debug: output data independent warnings and infoPádraig Brady
* src/sort.c (usage): Mention --debug can output warnings to stderr. Also split the translatable string to aid translation. (default_key_compare): A new function refactored from main(), and now also called from the new key_warnings() function. (key_to_opts): A new function refactored from incompatible_options(), and now also called from the new key_warnings() function. (key_numeric): A new function refactored to test if key is numeric. (key_warnings): A new function to output warnings to stderr, about questionable use of various options. Currently it warns about zero length keys and ineffective global options. (incompatible_options): Refactor out key_to_opts() (main): Use key_init() to initialize gkey. Refactor out default_key_compare(). Call key_warnings() in debug mode. * doc/coreutils.texi (sort invocation): Mention that warnings are output by --debug. * tests/misc/sort-debug-warn: A new test for debug warnings. * tests/Makefile.am: Reference the new test. * NEWS: Mention the new feature
2010-05-12sort: add a --debug option to highlight key extentsPádraig Brady
* src/sort (usage): Add description for --debug. (write_bytes): Pass a line structure so it can subsequently be passed to compare to highlight the keys when in debug mode. Also transform TAB and NUL characters written to stdout so that the highlighting in debug mode aligns correctly. (human_numcompare): Pass an "endptr" so we can record the extent of the number matched. (general_numcompare): Likewise. (find_unit_order): Likewise. (getmonth): Likewise. (numcompare): Likewise. Note we reuse find_unit_order() for this, which is a good enough approximation, and means we don't need to change the strnumcmp() interface. (check_mixed_SI_IEC): Return whether iec_present, so that can be used to set the "endptr" in find_unit_order. Also make the key parameter optional, which will be the case from numcompare(). (count_tabs): A new function to determine how much to adjust the mbswidth() values by (TABs don't have a width). (mark_key): A new function to output the key highlighting to stdout. (debug_key): A new function to determine the offset and width of the key highlighting. (key_compare): Pass the show_debug parameter so the key highlighting is only displayed when explicitly called. For each key type, set the length (lena) and whether leading blanks are auto skipped (skipb) which are then used by debug_key() to highlight the portion of the key used in the comparison. (compare): Pass the show_debug parameter so the key highlighting is only displayed when explicitly called. Call debug_key() to highlight the last resort comparison. (check): Output highlighting for disorder line to stdout. (main): Process the --debug option and make it mutually exlusive with the -o option as I don't see it useful there, even potentially harmful if someone left a --debug in by mistake when updating a file. Also restricting debug output to stdout, simplifies the logic for dealing with temporary files. * doc/coreutils.texi (sort invocation): Describe the --debug option, and reference it from the --key description. * tests/misc/sort-debug-keys: A new test for highlighting keys. * tests/Makefile.am: Reference the new test. * NEWS: Mention the new feature.
2010-04-29sort: use long doubles for general numeric modePádraig Brady
* src/sort.c (general_numcompare): Use long doubles unconditionally, and strtold when available, to convert numbers with greater range and precision. Performance was seen to be on par with standard doubles. * doc/coreutils.texi (sort invocation): Amend the -g description to mention long double rather than double, and strtold rather than strtod. * src/getlimits.c (main): Output floating point limits for use in tests. * tests/misc/sort-float: A new test to ensure sort is using long doubles when possible, and that locale specific floats are handled. * tests/Makefile.am: Reference the new test. * tests/test-lib.sh (getlimits_): Normalize indenting. * NEWS: Mention the new behaviour. Reported by Nelson Beebe.
2010-04-25doc: tweak factor-describing wordingJim Meyering
* doc/coreutils.texi (factor invocation): Don't say that "factoring large prime numbers is hard". A pedant might ding you, since it's trivial to factor a number that is known to be prime. Instead, say that "factoring large numbers... is hard". Reported by Andreas Eder.
2010-04-21docs: document transformation of obsolete sort syntaxEric Blake
* doc/coreutils.texi (sort invocation): Mention the conversion.
2010-04-12doc: clarify when cp and mv output xattr warningsPádraig Brady
The 2010-03-26 commit, 4c38625e, "doc: fix info on cp --preserve..." was not entirely correct as cp --preserve=all does produce some xattr warnings. * src/copy.h: Update and clarify the comments for reduce_diagnostics and require_preserve_{xattr,context}. * doc/coreutils.texi (cp invocation): Update the -a and --preserve=xattr,context options to say when and which xattr warnings are output. (mv invocation): Mention that some warnings are output when preserving xattrs.
2010-04-11doc: mention that "capabilities" are preserved by cp/mvPádraig Brady
* doc/coreutils.texi (cp invocation): Mention that "capabilities" are preserved when implemented using extended attributes. (mv invocation): Mention ACLs etc. are maintained due to xattrs being copied.
2010-03-26doc: fix info on cp --preserve=all, which does _not_ give xattr warningsPádraig Brady
The info docs have been inaccurate since 2009-04-17, commit 941bd482, "mv: ignore xattr-preservation failure when not supported by filesystem" * doc/coreutils.texi (cp invocation): Say that cp --preserve=all does _not_ output errors when failing to copy xattrs.
2010-03-16timeout: add the --kill-after optionPádraig Brady
Based on a report from Kim Hansen who wanted to send a KILL signal to the monitored command when `timeout` itself received a termination signal. Rather than changing such a signal into a KILL, we provide the more general mechanism of sending the KILL after the specified grace period. * src/timeout.c (cleanup): If a non zero kill delay is specified, (re)set the alarm to that delay, after which a KILL signal will be sent to the process group. (usage): Mention the new option. Separate the description of DURATION since it's now specified in 2 places. Clarify that the duration is an integer. (parse_duration): A new function refactored from main(), since this logic is now called for two parameters. (main): Parse the -k option. * doc/coreutils.texi (timeout invocation): Describe the new --kill-after option and use @display rather than @table to show the duration suffixes. Clarify that a duration of 0 disables the associated timeout. * tests/misc/timeout-parameters: Check invalid --kill-after. * tests/misc/timeout: Check a valid --kill-after works. * NEWS: Mention the new feature.
2010-03-13doc: use mktemp, not tempfile, in a shred usage exampleThien-Thi Nguyen
* doc/coreutils.texi (shred invocation): Use mktemp(1) instead of Debian-specific tempfile(1).
2010-03-09doc: Add an example for cutting fields separated by runs of blanksPádraig Brady
* doc/coreutils.texi (cut invocation): Show how tr can be used to process the input for cut in this case. Suggestion from Dan Jacobson.
2010-02-15dirname: improve man page descriptionEric Blake
* doc/coreutils.texi (dirname invocation): Properly cover behavior on directory. * man/dirname.x: Likewise. * THANKS: Update. Reported by Emmanuel Lacour.
2010-02-01join: make -t '' operate on the whole linePádraig Brady
Previously passing an empty parameter to -t would raise an error, but now it means to treat each line as a single field for matching. This matches the default operation of `sort` which is usually used in conjunction with join. * src/join.c (main): Set the field delimiter to '\n' if an empty parameter is passed to -t. (usage): Mention the operation of -t ''. * tests/misc/join: Add 2 new tests, for the existing -t '\0' and the new -t '' functionality. * doc/coreutils.texi (join invocation): Mention that join -t '' always operates on the whole line, while join -t '\0' usually does. * NEWS: Mention the change in behavior.
2010-02-01join: add --header option to always output the first lineAssaf Gordon
This essentially allows one to use --check-order with headings. Note join without --check-order will already handle the common case where headings do match in each file, however using --check-order will fail often when the header sorts after the first line of data. Note also that this will join header lines from each file even if they don't match, with headings from the first file being used. * NEWS: Mention the new option. * doc/coreutils.texi (join invocation): Describe the new option. * src/join.c (usage): Likewise. (join): Join the header lines unconditionally. * tests/misc/join: Add 5 new tests.
2010-01-23doc: add nproc to the texinfo overview menuPádraig Brady
* doc/coreutils.texi: Add nproc to the System context command list in the overview menu.
2010-01-01maint: update all FSF copyright year lists to include 2010Jim Meyering
Use this command: git ls-files | grep -v COPYING \ | xargs env UPDATE_COPYRIGHT_USE_INTERVALS=1 \ build-aux/update-copyright
2009-12-31doc: update tail's documentation to allow for new -F semanticsJim Meyering
* src/tail.c (usage): Reword tail -F description, so that it no longer mentions details specific to the non-inotify implementation. Also, join diagnostic strings (while staying under the 509-byte limit) to ease formatting of translations. The latter was prompted by a report from Stéphane Raimbault. * doc/coreutils.texi (tail invocation): Update description here, too.
2009-12-29maint: quiet "make" in doc/Jim Meyering
* doc/Makefile.am (constants.texi): Add a use of AM_V_GEN.
2009-12-19doc: enhance and reference info about version comparisonPádraig Brady
* doc/coreutils.texi (sort invocation): Reference the additional info about filevercmp rather than the unused strverscmp. (Details about version sort): Add some examples that are not handled well by fileversmp. * src/ls.c: Change a comment referencing the now unused strverscmp.
2009-11-10doc: fix typoEric Blake
* doc/coreutils.texi (mktemp invocation): Quote shell variable.

2009-11-05mktemp: add suffix handlingEric Blake
Now that mkstemps is supported, we might as well use it. * src/mktemp.c (TMPDIR_OPTION): New enum value. (longopts): Add new option. (usage): Document it. (count_trailing_X_s): Rename... (count_consecutive_X_s): ...to this, and add parameter. (mkstemp_len, mkdtemp_len): Add parameter. (main): Implement new option. (AUTHORS): Add myself. * AUTHORS (mktemp): Likewise. * tests/misc/mktemp: Test new option. * doc/coreutils.texi (mktemp invocation): Document it. * NEWS: Likewise. Fixes http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=548316.

2009-10-28echo, printf: interpret \e as the Escape characterPádraig Brady
Match gcc, perl, bash, ksh, tcsh, ... in supporting \e. * src/printf.c (print_escape_char): Output \x1B when \e encountered. * src/echo.c (main): Likewise. * src/stat.c (print_escape_char): Likewise. * doc/coreutils.texi (echo invocation): Add \e to the list. * tests/misc/printf: Verify that \e outputs \x1B. * NEWS: Mention the change in behaviour.
2009-10-27doc: turn env comments into documentationEric Blake
* src/env.c: Convert introductory comments... * doc/coreutils.texi (env invocation): ...into documentation. Suggested by Jim Meyering.
2009-10-27env, printenv: add -0/--null optionEric Blake
Allows for unambiguous processing when environment values (or even non-portable names!) contain newline. * src/env.c (longopts): Add new option. (usage): Document it. (main): Implement it. * src/printenv.c (longopts): New variable. (usage): Document new option. (main): Implement it. * doc/coreutils.texi (Common options): New macro optNull. (du invocation, env invocation, printenv invocation): Use it. * NEWS: Mention this. * tests/misc/env-null: New test. * tests/Makefile.am (TESTS): Run it.
2009-10-26tests: clean up tests of env -- handlingEric Blake
The comment in env.c about -- handling has not matched the behavior in the code since the initial commit back in 1992. * src/env.c: Fix bogus comment. * tests/misc/env: Further tweaks, avoiding PATH problems inherent in testing -i, and testing program name containing =. * doc/coreutils.texi (env invocation): Mention that intermediate program is needed to invoke program with name containing =.
