2013-09-22id: support specifying the user by user IDPádraig Brady
* src/id.c (usage): Remove 'name' from the synopsis, implying that one can also specify by user ID. (main): Like chown(1), call parse_user_spec() to implement user name or ID lookup with appropriate precedence. * doc/coreutils.texi (id invocation): Mention that a user ID is supported and how '+' affects lookup order. * tests/misc/id-groups.sh: Remove test now subsumed into... * tests/misc/id-uid.sh: New test covering new interface. * tests/local.mk: Rename the test. * NEWS: Mention the new feature. Addresses http://bugs.gnu.org/15421
2013-09-22tests: avoid a failure when there isn't a name for all user IDsPádraig Brady
* tests/misc/id-zero.sh: Don't check exit status when in -n mode. Prompted by the continuous integration build failure at: http://hydra.nixos.org/build/6196762
2013-09-21id: add -z, --zero optionBernhard Voelker
* src/group-list.h (print_group_list): Add a parameter for the delimiter of type char. * src/group-list.c (print_group_list): Likewise, and use it instead of a white space character to delimit the group entries. * src/groups.c (main): Pass white space character to print_group_list(). * src/id.c (longopts): Add array element for the new long option. (usage): Document the new option. While at it, fix the alignment of the descriptions to match that of HELP_OPTION_DESCRIPTION. (main): Define the bool flag opt_zero indicating the use of the new option. In the getopt_long loop, handle it. Output an error diagnostic in the case the --zero option has been specified together with the default format. In the case of -gG, pass either a NUL or a white space character to print_group_list() - depending on the above new flag. Likewise change the printing of the final newline character: output a NUL instead if the --zero option has been specified. * doc/coreutils.texi (id invocation): Document the new option. While at it, move the @exitstatus macro down after the macro @primaryAndSupplementaryGroups in order to be consistent with other texinfo documents. (groups invocation): Move @exitstatus down after the macro @primaryAndSupplementaryGroups here, too. * tests/misc/id-zero.sh: Add new test exercising the new option. * tests/local.mk (all_tests): Reference it. * NEWS (New features): Mention the new option. Fixes http://bugs.gnu.org/9987
2013-08-02maint: update copyright year number ranges of numfmt sourcesBernhard Voelker
Run "make update-copyright". * src/numfmt.c: Update copyright year number range. This file has obviously been added to coreutils after and without the annual update. * tests/misc/numfmt.pl: Likewise.
2013-07-22maint: make some shell and perl scripts executable in 'tests/'Bernhard Voelker
Some newer test scripts - partially ones from me - are not executable. It does not seem to be a problem, but for consistency and to avoid future problems on unusual platforms or shells change the permissions by adding the executable bit. * cfg.mk (sc_tests_executable): Add new syntax-check rule to ensure that all test scripts are executable. * tests/df/df-output.sh: Change file mode from 644 to 755. * tests/du/threshold.sh: Likewise. * tests/factor/run.sh: Likewise. * tests/init.sh: Likewise. * tests/misc/csplit-suppress-matched.pl: Likewise. * tests/misc/numfmt.pl: Likewise. * tests/tail-2/retry.sh: Likewise.
2013-07-11shuf: add --repetition to support repetition in outputAssaf Gordon
main(): Process new option. Replace input_numbers_option_used() with a local variable. Re-organize argument processing. usage(): Describe the new option. (write_random_numbers): A new function to generate a permutation of the specified input range with repetition. (write_random_lines): Likewise for stdin and --echo. (write_permuted_numbers): New function refactored from write_permuted_output(). (write_permuted_lines): Likewise. * tests/misc/shuf.sh: Add tests for --repetitions option. * doc/coreutils.texi: Mention --repetitions, add examples. * TODO: Mention an optimization to avoid needing to read all of the input into memory with --repetitions. * NEWS: Mention new shuf option.
2013-07-11tests: add more tests for shuf option combinationsAssaf Gordon
* test/misc/shuf.sh: Add tests for erroneous conditions like multiple '-o' and '--random-source'.
2013-07-05tests: fix "shuf unreadable" test to work when run as rootPádraig Brady
* tests/misc/shuf.sh: Restrict the test to the significant case where we can't in fact read the "unreadable" file.
2013-06-22stdbuf: make it mandatory to specify a buffering optionPádraig Brady
This is consistent with the documented interface and avoids any ambiguity in a user thinking that stdbuf without options might reset to a "standard" buffering setup. * src/stdbuf.c (set_libstdbuf_options): Indicate with the return value whether any env variables were actually set. (main): Fail unless some env variables were set. * tests/misc/stdbuf.sh: Ensure this constraint is enforced. * NEWS: Mention the small change in behavior.
2013-06-02od: -wN, N>64K, avoid misbehavior on systems with 32-bit size_tJim Meyering
* src/od.c (PRINT_FIELDS): Declare "i" to be of type uintmax_t, so that the numerator in the expression for "next_pad" does not overflow. (print_named_ascii): Likewise. (print_ascii): Likewise. Bug introduced via commit v6.12-42-g20c0b87. * tests/misc/od.pl: Exercise each of the three affected code paths. * NEWS (Bug fixes): Mention it. Reported by Rich Burridge.
2013-06-01tests: head-c: avoid spurious failure with a 32-bit size_tJim Meyering
* tests/misc/head-c.sh: Don't try to elide 1 exabytes, since on 32-bit systems, that number is not representable as a size_t. This command would fail on 32-bit systems, where SIZE_MAX < 1E: head --bytes=-E < /dev/null Instead of "E", use $SSIZE_MAX. For discussion, see http://bugs.gnu.org/13530
2013-05-27tests: numfmt: use the printf program, not the shell builtinStefano Lattarini
* tests/misc/numfmt.pl: Avoid a spurious failure when /bin/sh is dash (as can happen on Debian systems).
2013-05-18tests: don't assume expr was built with GMPPaul Eggert
* tests/misc/cut-huge-range.sh (subtract_one): New string. (CUT_MAX): Don't pass a too-large integer to 'expr'.
2013-05-08cut: improve performance, especially with --output-delimiterCojocaru Alexandru
Use a sentinel value that's checked implicitly, rather than a bit array, to determine if an item should be output. Benchmark results for this change are: $ yes abcdfeg | head -n1MB > big-file $ for c in orig sentinel; do src/cut-$c 2>/dev/null echo -ne "\n== $c ==" time src/cut-$c -b1,3 big-file > /dev/null done == orig == real 0m0.049s user 0m0.044s sys 0m0.005s == sentinel == real 0m0.035s user 0m0.032s sys 0m0.002s ## Again with --output-delimiter ## $ for c in orig sentinel; do src/cut-$c 2>/dev/null echo -ne "\n== $c ==" time src/cut-$c -b1,3 --output-delimiter=: big-file > /dev/null done == orig == real 0m0.106s user 0m0.103s sys 0m0.002s == sentinel == real 0m0.055s user 0m0.052s sys 0m0.003s eol_range_start: Removed. 'n-' is no longer treated specially, and instead SIZE_MAX is set for the 'hi' limit, and tested implicitly. complement_rp: Used to complement 'rp' when '--complement' is specified. ADD_RANGE_PAIR: Macro renamed to 'add_range_pair' function. * tests/misc/cut-huge-range.sh: Adjust to the SENTINEL value. Also remove the overlapping range test as this is no longer dependent on large ranges and also is already handled with the EOL-subsumed-3 test in cut.pl.
2013-05-07cut: fix handling of overlapping rangesCojocaru Alexandru
This issue was introduced in commit v8.21-43-g3e466ad * src/cut.c (set_fields): Process all range pairs when merging. * tests/misc/cut-huge-range.sh: Add a test for this edge case. Also fix an issue where we could miss reported errors due to truncation of the 'err' file.
2013-04-29cut: reduce CPU overhead in determining item to outputCojocaru Alexandru
print_kth() is the central function of cut used to determine if an item is to be output or not, so simplify it by moving some logic outside. Benchmark results for this change are: $ yes abcdfeg | head -n1MB > big-file $ for c in orig split; do src/cut-$c 2>/dev/null echo -ne "\n== $c ==" time src/cut-$c -b1,3 big-file > /dev/null done == orig == real 0m0.111s user 0m0.108s sys 0m0.002s == split == real 0m0.088s user 0m0.081s sys 0m0.007s * src/cut.c (print_kth): Refactor a branch to outside the function. Related to http://bugs.gnu.org/13127
2013-04-29cut: make memory allocation independent of range widthCojocaru Alexandru
The current implementation of cut, uses a bit array, an array of `struct range_pair's, and (when --output-delimiter is specified) a hash_table. The new implementation will use only an array of `struct range_pair's. The old implementation is memory inefficient because: 1. When -b with a big num is specified, it allocates a lot of memory for `printable_field'. 2. When --output-delimiter is specified, it will allocate 31 buckets. Even if only a few ranges are specified. Note CPU overhead is increased to determine if an item is to be printed, as shown by: $ yes abcdfeg | head -n1MB > big-file $ for c in with-bitarray without-bitarray; do src/cut-$c 2>/dev/null echo -ne "\n== $c ==" time src/cut-$c -b1,3 big-file > /dev/null done == with-bitarray == real 0m0.084s user 0m0.078s sys 0m0.006s == without-bitarray == real 0m0.111s user 0m0.108s sys 0m0.002s Subsequent patches will reduce this overhead. * src/cut.c (set_fields): Set and initialize RP instead of printable_field. * src/cut.c (is_range_start_index): Use CURRENT_RP rather than a hash. * tests/misc/cut.pl: Check if `eol_range_start' is set correctly. * tests/misc/cut-huge-range.sh: Rename from cut-huge-to-eol-range.sh, and add a test to verify large amounts of mem aren't allocated. Fixes http://bugs.gnu.org/13127
2013-04-25tests: fix usage of require_ulimit_Pádraig Brady
* init.cfg (require_ulimit_v_): Renamed from require_ulimit_ as this only checks for ulimit -v support. Other uses of ulimit -t and ulimit -n in tests shouldn't cause false failures if not supported. * cfg.mk (sc_prohibit_test_ulimit_without_require_): A new syntax check to ensure that require_ulimit_v_() is used iff required. * tests/misc/head-c.sh: Add missing call to require_ulimit_v_. * tests/rm/many-dir-entries-vs-OOM.sh: Likewise. * tests/split/r-chunk.sh: Remove non mandatory require_ulimit_ call. * tests/misc/sort-merge-fdlimit.sh: Likewise. * tests/cp/link-heap.sh: Adjust to renamed require_ulimit_v_. * tests/dd/no-allocate.sh: Likewise. * tests/misc/csplit-heap.sh: Likewise. * tests/misc/cut-huge-to-eol-range.sh: Likewise. * tests/misc/printf-surprise.sh: Likewise.
2013-04-14head: with --bytes=-N only allocate memory as neededPádraig Brady
* src/head.c (elide_tail_bytes_pipe): Don't use calloc as that bypasses memory overcommit due to the zeroing requirement. Also realloc rather than malloc the pointer array to avoid dependence on overcommit entirely. * tests/misc/head-c.sh: Add a test case. Fixes http://bugs.gnu.org/13530
2013-04-10csplit: add the --suppress-matched optionAssaf Gordon
With --suppress-matched, the lines that match the pattern will not be printed in the output files. I.E. the first line from the second and subsequent splits will be suppressed. * src/csplit.c: process_regexp(),process_line_count(): Don't output the matched lines. Since csplit includes "up to but not including" matched lines in each split, the first line (in the next group) is the matched line - so just skip it. main(): Handle new option. usage(): Mention new option. * doc/coreutils.texi (csplit invocation): Mention new option, examples. * tests/misc/csplit-suppress-matched.pl: New test script. * tests/local.mk: Reference the new test. * NEWS: Mention new feature.
2013-04-04shuf: exit without reading if would never outputPádraig Brady
* src/shuf.c (main): If -n0 specified then no data would ever be output, so exit without reading input. * tests/misc/shuf.sh: Augment the related test with this case.
2013-03-25shuf: use reservoir-sampling for large or unknown sized inputsAssaf Gordon
Reservoir sampling optimizes selecting K random lines from large or unknown-sized input: http://en.wikipedia.org/wiki/Reservoir_sampling Note this also avoids reading any input when -n0 is specified. * src/shuf.c (main): Use reservoir-sampling when the number of output lines is known, and the input size is large or unknown. (input_size): A new function to get the input size for regular files. (read_input_reservoir_sampling): New function to read lines from input, keeping only K lines in memory, replacing lines with decreasing prob. (write_permuted_output_reservoir): New function to output reservoir. * tests/misc/shuf-reservoir.sh: An expensive_ test using valgrind to exercise the reservoir-sampling code. * tests/local.mk: Reference new test. * NEWS: Mention the improvement.
2013-02-28tests: don't skip all uniq tests when locale is missingAssaf Gordon
* tests/misc/uniq.pl: Previously, if LOCALE_FR was not defined, all tests would be skipped. Modified to skip only the relevant test.
2013-02-28uniq: add the --group optionAssaf Gordon
* src/uniq.c (usage): Summarize the new option, and adjust the --all-repeated option to be more consistent. (check_file): Merge the --group functionality into the core loop for the default uniq operation since it's very similar and can output lines immediately upon reading. (main): Handle the new --group option and make it mutually exclusive with other selection options. * tests/misc/uniq.pl: Add tests. * NEWS: Mention the new feature. * doc/coreutils.texi (uniq invocation): Describe --group.
2013-02-28doc: move some info from all --help messages, onlinePádraig Brady
* src/system.h (emit_ancillary_info): Link to the bug report email addresses and general help URLs online rather than specifying directly. This give us greater scope to present better info like describing the difference between bug-coreutils@gnu.org and coreutils@gnu.org etc. * tests/misc/help-version.sh: Remove the check for bug-coreutils@gnu.org * tests/local.mk: Remove the no longer needed PACKAGE_BUGREPORT.
2013-02-28tests: add '--ignore-case' tests for uniqAssaf Gordon
* tests/misc/uniq.pl: add tests for --ignore-case.
2013-02-28join: Add the -z, --zero-terminated optionAssaf Gordon
* NEWS: Mention join's new option: --zero-terminated (-z). * src/join.c: Add new option, --zero-terminated (-z), to make join use the NUL byte as separator/delimiter rather than newline. (get_line): Use readlinebuffer_delim in place of readlinebuffer. (main): Handle the new option. (usage): Describe new option the same way sort does. * doc/coreutils.texi (join invocation): Describe the new option. * tests/misc/join.pl: add tests for -z option.
2013-02-10maint: consolidate developer debug messagesPádraig Brady
Both factor and numfmt recently introduced debug messages for developers, enabled by --verbose and ---devdebug respectively. There were a few issues though: 1. They used different mechanisms to enable these messages. 2. factor used --verbose which might be needed for something else 3. They used different methods to output the messages, and numfmt used error() which added an unwanted newline 4. numfmt marked all these messages for translation and factor marked a couple. We really don't need these translated. So we fix the above issues here while renaming the enabling option for both commands to ---debug (still undocumented). * src/factor.c (verbose): Rename to dev_debug and change from int to bool as it's just a toggle flag. (long_options): Rename --verbose to ---debug. * src/system.h (devmsg): A new inline function to output a message if enabled by a global dev_debug variable in the compilation unit. * src/numfmt.c: Use devmsg() rather than error(). Also remove the translation tags from these messages. Also change debug flag to bool from int. * tests/misc/numfmt.pl: Adjust for the ---devdebug to ---debug change. * cfg.mk (sc_marked_devdiagnostics): Add a syntax check to ensure translations are not added to devmsg calls. Reported by Göran Uddeborg in http://bugs.gnu.org/13665
2013-02-10tests: skip numfmt grouping tests on some systemsPádraig Brady
* tests/misc/numfmt.pl: When the system locale grouping doesn't match our expected format for grouping 1234 in the fr_FR locale, reset the locale to 'C' so as to skip all locale tests.
2013-02-05stty: add support for DTR/DSR hardware control flowOndřej Vašík
Originally requested in Red Hat bugzilla #445213. * src/stty.c (mode_info): Add support for DTR/DSR hardware flow control, if available. * doc/coreutils.texi: Document it. * tests/misc/stty.sh: Add it to the list of serial options to avoid. * NEWS: Mention the improvement.
2013-02-04numfmt: a new command to format numbersAssaf Gordon
* AUTHORS: Add my name. * NEWS: Mention the new program. * README: Reference the new program. * src/numfmt.c: New file. * src/.gitignore: Ignore the new binary. * build-aux/gen-lists-of-programs.sh: Update. * scripts/git-hooks/commit-msg: Allow numfmt: commit prefix. * po/POTFILES.in: Add new c file. * tests/misc/numfmt.pl: A new test file giving >93% coverage. * tests/local.mk: Reference the new test. * man/.gitignore: Ignore the new man page. * man/local.mk: Reference the new man page. * man/numfmt.x: A new template. * doc/coreutils.texi: Document the new command.
2013-02-04cut: fix a segfault with disjoint open ended rangesPádraig Brady
Fixes the issue introduced in unreleased commit v8.20-60-gec48bea. * src/cut.c (set_fields): Don't access the bit array if we've an open ended range that's outside any finite range. * tests/misc/cut.pl: Add tests for this case. Reported by Marcel Böhme in http://bugs.gnu.org/13627
2013-01-26timeout: ensure a blocked SIGALRM from the parent is unblockedStephan Krempel
* src/timeout.c (unblock_signal): A new function to unblock a specified signal, or warn if not possible. (set_timeout): Ensure SIGALRM is unblocked before we setup the timer. * tests/misc/timeout-blocked.pl: A new test for the issue. * tests/local.mk: Reference the new test. * NEWS: Mention the fix. Fixes: http://bugs.gnu.org/13535
2013-01-26seq: fix to always honor the step valuePádraig Brady
* src/seq.c (main): With 3 positive integer args we were checking the end value was == "1", rather than the step value. * tests/misc/seq.pl: Add tests for this case. Reported by Marcel Böhme in http://bugs.gnu.org/13525
2013-01-26seq: fix misaligment with -w when no precision for start valuePádraig Brady
* src/seq.c (get_default_format): Also account for the case where '.' is auto added to the start value, which is significant when the number sequence narrows. * tests/misc/seq.pl: Add two new tests for the failing cases. * NEWS: Mention the fix. Fixes http://bugs.gnu.org/13394
2013-01-26cut: fix -f to work with the -d$'\n' edge casePádraig Brady
* src/cut.c (cut_fields): Handle the edge case where '\n' is the delimiter, which could be used for example to suppress the last line if it doesn't contain a '\n'. * test/misc/cut.pl: Add tests for this edge case.
2013-01-26cut: with -f, process each line independentlyPádraig Brady
Previously line N+1 was inspected before line N was fully output, which causes output ordering issues at the terminal or delays from intermittent sources like tail -f. * src/cut.c (cut_fields): Adjust so that we record the previous output character so we can use that info to determine wether to output a '\n' or not. * tests/misc/cut.pl: Add tests to ensure existing functionality isn't broken. * NEWS: Mention the fix. Fixes bug http://bugs.gnu.org/13498
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.
2012-12-21seq: fix newline output when -s specifiedPádraig Brady
This regression was introduced in commit v8.19-132-g3786fb6. * src/seq.c (seq_fast): Don't use puts() to output the first number, and instead insert it into the buffer as for other numbers. Also output the terminator unconditionally. * tests/misc/seq.pl: Add some basic tests for the -s option. * NEWS: Mention the fix. * THANKS.in: Reported by Philipp Gortan.
2012-12-20tests: add tests for basename's --zero optionBernhard Voelker
The -z option has been introduced in commit v8.15-60-ga3eb71a, i.e. in coreutils-8.16. Time to add some tests for it. * tests/misc/basename.pl: Add tests exercising the -z option. In the foreach loop to append a newline to the end of each expected 'OUT' string, skip the -z tests.
2012-12-19tests: avoid a race in timeout-group.shPádraig Brady
* tests/misc/timeout-group.sh: The kernel might possibly delay signal propagation to timeout.cmd long enough, that it exits normally without running the signal handler (as sleep will be in the same process group and so get the signal too). So avoid this by explicitly checking that the signal handler is called, which should always happen under normal circumstances. Reported by Stefano Lattarini on linux-2.6.30-2-686 and bash-4.2.36.
2012-12-09tests: add test case and note that last week's cut change is a bug fixJim Meyering
* tests/misc/cut-huge-to-eol-range.sh: New test, showing that the change in v8.20-51-g7d03466 is a bug fix after all. * tests/local.mk (all_tests): Add it. * NEWS (Bug fixes): Mention it.
2012-12-06maint: fix a referenced coreutils version in a test commentPádraig Brady
* tests/misc/cut.pl: This particular bug existed up to v8.10.
2012-12-06tests: cut.pl: adjust for changed diagnosticPádraig Brady
* tests/misc/cut.pl: Since we now output the more complete error message irrespective of running in a multi-byte locale or not, adjust the test accordingly.
2012-12-06cut: improve error reportingCojocaru Alexandru
* src/cut.c (main): Treat a NUL delimiter (-d '') consistently with non NUL delimiters, and disallow such a delimiter option, unless a field is also specified. (set_fields): Provide a more accurate error message when a given list is invalid. * tests/misc/cut.pl: Add a test case.
2012-11-24cut: do not print extraneous delimiters in some unusual casesJim Meyering
When printing output delimiters, and when a to-EOL range subsumes at least one other range, cut would mistakenly print delimiters for the subsumed range. This bug was probably introduced via commit v5.2.1-639-g847e066. * src/cut.c (set_fields): Ignore any range that is subsumed by a to-EOL range. Also, move two declarations down. * tests/misc/cut.pl: Add tests to exercise this. * NEWS (Bug fixes): Mention it. Reported by Marcel Böhme in http://bugs.gnu.org/12966
2012-11-24cut: treat -b2-,3- like -b2-, not like -b3-Jim Meyering
* src/cut.c (set_fields): When two right-open-ended ranges are specified, don't blindly let the latter one take precedence over the former. Instead, use the union of the ranges. * tests/misc/cut.pl: Add tests to exercise this. * NEWS (Bug fixes): Mention it. Reported by Marcel Böhme in http://bugs.gnu.org/12966 Thanks to Berhard Voelker for catching log and NEWS typos.
2012-11-24tests: use sub-second timeouts to speed up a timeout testPádraig Brady
* tests/misc/timeout.sh: Take advantage of recent support for sub-second timeouts to decrease runtime from about 6s to 2s.
2012-11-24seq: ensure correct output width for scientific notation inputPádraig Brady
* src/seq.c (scan_arg): Calculate the width more accurately for numbers specified using scientific notation. * tests/misc/seq.pl: Add tests for cases that were mishandled. * NEWS: Mention the fix. * THANKS.in: Reported by Marcel Böhme. Fixes http://bugs.gnu.org/12959
2012-11-19cut: do not accept the invalid range 0-Bernhard Voelker
The command "echo 12345 | cut -b 0-" prints an empty line while it should fail with "fields and positions are numbered from 1". * src/cut.c (set_fields): Add a diagnostic for the invalid open range which starts with Zero, i.e., the range 0-. * tests/misc/cut.pl: Add tests to ensure the range 0- fails for fields (-f) and for positions (-b, -c). * NEWS: Mention the fix. Reported by Marcel Böhme in <http://bugs.gnu.org/12903>.
