2015-12-17tests: avoid intermittent ulimit -v failuresPádraig Brady
* init.cfg (get_min_ulimit_v_): Increase the determined virtual memory limit for the command by a page size to avoid alignment issues causing false failures for subsequent runs. * tests/misc/cut-huge-range.sh: Be defensive and match the cut invocations under test, more closely with the form used to determine the VM memory limit. This was noticed on i686 linux at: http://hydra.nixos.org/build/28990456
2015-12-15maint: include 'env' commands in returns_ syntax checkPádraig Brady
* cfg.mk (sc_prohibit_and_fail_1): Remove 'env' from the exclusion list. * tests/misc/env.sh: Adjust accordingly. * tests/misc/help-version.sh: Likewise.
2015-12-15tests: improve kill testsPádraig Brady
* tests/misc/kill.sh: - verify kill -[lt] support multiple parameters. - verify kill -[lt] fail with (some) invalid parameters. - Use returns_1 ... || fail=1, rather than ... && fail=1.
2015-12-14sort: fix --debug marking for -b -k1.xPádraig Brady
We were erroneously skipping blanks in the marked comparison _after_ the key start offset was applied. * src/sort.c (debug_keys): Don't skip starting blanks if already handled by begfield(). * tests/misc/sort-debug-keys.sh: Add a test case. * NEWS: Mention the bug fix. Fixes http://bugs.gnu.org/22155
2015-12-14kill: add undocumented -L for compatibilityPádraig Brady
procps, bash >= 4.4, and util-linux >= 2.23 all have the -L option to output a table. * src/kill.c (main): Have -L synonymous with -t. Luckily there is no signal that begins with 'L'. * tests/misc/kill.sh: Update the test.
2015-12-14tests: add tests for the kill commandPádraig Brady
* tests/misc/kill.sh: Add first tests for kill. * tests/local.mk: Reference the new test.
2015-12-14maint: fix incorrect spellings etcPádraig Brady
* NEWS: Use a standard version specification. * doc/coreutils.texi: Fix incorrect grammar. * src/df.c: Update a stale comment. * src/copy.c: Fix incorrect spellings. * src/factor.c: Likewise. * src/ls.c: Likewise. * src/pr.c: Likewise. * src/relpath.c: Likewise. * src/shred.c: Likewise. * src/sort.c: Likewise. * src/split.c: Likewise. * src/stdbuf.c: Likewise. * tests/misc/seq-precision.sh: Likewise.
2015-11-23md5sum,sha*sum: ensure --ignore-missing fails when no file verifiedPádraig Brady
* src/md5sum.c (digest_check): Update a matched_checksums bool upon matched checksum, and fail (loudly unless --status is specified) if there were no matches. Also change properly_formatted_lines to a bool while at it since we don't need to track the plurality. * tests/misc/md5sum.pl: Add a test case. Suggested by Jim Meyering.
2015-11-23md5sum,sha*sum: add --ignore-missing for checking a subset of filesLuther Thompson
* doc/coreutils.texi (md5sum invocation): Document the new option. * src/md5sum.c (digest_file): Return an empty digest to indicate a missing file. (digest_check): Don't fail or output status given an empty checksum. (usage): Document the new option. (main): Process and validate the new option. * tests/misc/md5sum.pl: Add new test cases. * NEWS: Mention the new feature. Fixes http://bugs.gnu.org/15604
2015-11-12csplit: check and report fwrite errors with errnoAssaf Gordon
discussed in: http://lists.gnu.org/archive/html/coreutils/2015-10/msg00091.html * src/csplit.c: (save_line_to_file): check fwrite failures, report and exit immediately instead of deferring to 'close_output'. * tests/misc/csplit-io-err.sh: test fwrite failure using LD_PRELOAD. * tests/local.mk: add new test.
2015-11-10tests: ensure programs are built before testingPádraig Brady
programs may not be built due to missing system dependencies, or any program can be excluded at configure time with --enable-no-install-program. So ensure we're not testing the system versions in these cases. * init.cfg (print_ver_): Call require_built_ first. * tests/misc/tty-eof.pl: Skip programs not built. * tests/Coreutils.pm (run_tests): Likewise. * tests/misc/ls-misc.pl: Use 'env test' rather than abs path. * tests/misc/test-diag.pl: Likewise. * tests/local.mk: Adjust include order for dependencies. * tests/misc/arch.sh: Remove redundant calls to require_built_. * tests/misc/chroot-fail.sh: Likewise. * tests/misc/groups-dash.sh: Likewise. * tests/misc/groups-version.sh: Likewise. * tests/misc/stdbuf.sh: Likewise. * tests/cp/acl.sh: Remove problematic call to print_ver_ [gs]etfacl. * tests/mv/acl.sh: Likewise. * cfg.mk (sc_env_test_dependencies): A new syntax check to enforce specifying dependencies with print_ver_ for programs specified through the env command. * du/bigtime.sh: Add new print_ver_ dependencies. * du/max-depth.sh: Likewise. * dd/ascii.sh: Likewise. * tests/ls/capability.sh: Likewise. * tests/ls/root-rel-symlink-color.sh: Likewise. * tests/misc/chroot-fail.sh: Likewise. * tests/misc/readlink-fp-loop.sh: Likewise. * tests/misc/sort-debug-keys.sh: Likewise. * tests/readlink/can-e.sh: Likewise. * tests/readlink/can-f.sh: Likewise. * tests/readlink/can-m.sh: Likewise. * tests/tail-2/inotify-race.sh: Likewise. * tests/tail-2/inotify-race2.sh: Likewise. * tests/touch/no-create-missing.sh: Likewise. * tests/touch/no-dereference.sh: Likewise. * tests/misc/printenv.sh: Tweak to avoid syntax check trigger. * tests/misc/help-version.sh: Likewise. * tests/misc/yes.sh: Likewise. * tests/misc/printf-quote.sh: Use previously unused $prog. * configure.ac (EXTRA_MANS): Add $gl_no_install_prog to the list so that check-x-vs-1 syntax check is satisfied.
2015-11-10maint: use standard spacing in shebang line in testsPádraig Brady
It's better to be consistent even though spacing is insignificant: http://www.in-ulm.de/~mascheck/various/shebang/#blankrequired
2015-11-10tests: cleanup trapping of signal namesPádraig Brady
A side effect of this cleanup is we no longer depend on our own kill command being built. * init.cfg (require_trap_signame_): A new function to verify that the shell supports specifying traps by signal name. (require_kill_group_): A new function to ensure the shell supports sending a signal to a group. * tests/du/move-dir-while-traversing.sh: Ensure trap supports signal names. * tests/misc/stty-invalid.sh: Likewise. * tests/misc/stty-pairs.sh: Likewise. * tests/misc/stty-row-col.sh: Likewise. * tests/misc/stty.sh: Likewise. * tests/misc/sort-compress.sh: Likewise. Also simplify trap call. * tests/install/trap.sh: Likewise. * tests/misc/timeout.sh: Likewise. * tests/dd/stats.sh: Likewise. Also use default kill command. * tests/misc/timeout-group.sh: Likewise.
2015-11-04paste: avoid confusing backslash quoting in diagnosticPádraig Brady
* src/paste.c (main): Setting the quoting style to "escape" went against the intent of the comment about presenting doubled backslashes to the user. Instead use "c-maybe" which is the only mode which avoids doubled backslashes, and provides protection against arbitrary control characters. * tests/misc/paste.pl: Adjust accordingly.
2015-11-04printf: support the %q format to quote for shellPádraig Brady
* src/printf.c (usage): Mention the new format. (print_formatted): Handle the quoting by calling out to the quotearg module with "shell-escape" mode. * doc/coreutils.texi (printf invocation): Document %q. * tests/misc/printf-quote.sh: New test. * tests/local.mk: Reference new test. * NEWS: Mention the new feature.
2015-11-04ls: avoid redundant processing when already escapingPádraig Brady
This is mainly noticeable when the multi-byte code within ls.c is triggered by multi-byte quotes. $ seq 200000 | xargs touch $ time ls-old -U --quoting=locale --hide-control-chars >/dev/null real 0m0.483s $ time ls-new -U --quoting=locale --hide-control-chars >/dev/null real 0m0.430s * src/ls.c (quote_name): Avoid rescanning the output looking for unprintable chars when we know the quoting mode already escapes them. * tests/misc/ls-misc.pl: Add tests for all quoting modes, with and without -q, to verify this assumption.
2015-11-04ls: document and test new shell-escape quotingPádraig Brady
* doc/coreutils.texi (ls invocation): Describe the new 'shell-escape' and 'shell-escape-always' quoting options. * src/ls.c (usage): Mention the new quoting options. * tests/misc/ls-misc.pl: Add a test for 'shell-escape'
2015-11-04all: avoid quoting file names when possiblePádraig Brady
Quote file names using the "shell-escape" or "shell-escape-always" methods, which quote as appropriate for most shells, and better support copy and paste of presented names. The "always" variant is used when the file name is embedded in an error message with surrounding spaces. * cfg.mk (sc_error_shell_quotes): A new syntax check rule to suggest quotef() where appropriate. (sc_error_shell_always_quotes): Likewise for quoteaf(). * src/system.h (quotef): A new define to apply shell quoting when needed. I.E. when shell character or ':' is present. (quoteaf): Likewise, but always quote. * src/*.c: Use quotef() and quoteaf() rather than quote() where appropriate. * tests/: Adjust accordingly.
2015-11-04md5sum: ensure a single status line per filePádraig Brady
* src/md5sum.c: Use the same file name escaping method used when generating and checking checksums. I.E. ensure a single line per file by starting the line with '\' for any file name containing '\n' and replacing those with "\\n". * NEWS: Move the item from changes in behavior to improvements, since this is no longer a backwards incompat change when processing stdout status messages. * tests/misc/md5sum.pl: Remove quotes from expected status output. * tests/misc/sha1sum.pl: Likewise.
2015-11-04all: replace most uses of quotearg_colon() with quote()Pádraig Brady
Related to commit v8.24-61-g6796698 this provides more consistent quoting, as quotearg_colon() defaults to "literal" quoting by default, while quote() provides appropriate quoting for diagnostics by default. * gl/modules/randread: Depend on quote module rather than quotearg. * gl/lib/randread.c: Used quote() not quotearg_colon(). * src/: Likewise. * src/shred.c: Likewise. Also avoid unnecessary quoting introducing overhead when wiping names. * cfg.mk: Relax the matching expression to allow "qname" variables as used in shred.c to satisfy the check. * tests/: Adjust accordingly.
2015-10-27date: use extended format timezone for --iso-8601Pádraig Brady
* src/date.c (main): Use %:z rather than %z with --iso-8601 as the standard states to consistently use extended format. Note either format can be parsed by date. * tests/misc/date.pl: Adjust accordingly. * doc/coreutils.texi (du invocation): Clarify that "iso" time styles are only similar to ISO-8601. (ls invocation): Likewise. (date invocation): Adjust the comment stating that only --rfc-3339 output can be parsed by date(1). * NEWS: Mention the change in behavior. Reported at http://bugs.debian.org/799479
2015-10-27all: quote string arguments in error messagesPádraig Brady
These strings are often file names or other user specified parameters, which can give confusing errors in the presence of unexpected characters for example. * cfg.mk (sc_error_quotes): A new syntax check rule. * src/*.c: Wrap error() string arguments with quote(). * tests/: Adjust accordingly. * NEWS: Mention the improvement.
2015-10-27md5sum: quote all printed file namesPádraig Brady
This is especially significant when using --check with files generated on a windows system, where the \r characters produce corrupted and confusing error messages. This also ensures status messages are output on a single line. * src/md5sum.c: Use quote() for printed file names. * tests/misc/md5sum.pl: Adjust accordingly. * NEWS: Mention the change in behavior. Fixes http://bugs.gnu.org/21757
2015-10-19tests: adjust recent change to csplit VM limitPádraig Brady
* tests/misc/csplit-heap.sh: A little more memory is required for the full run case. Noticed with --enable-single-binary.
2015-10-16dircolors: support globbing of TERM entriesPádraig Brady
* src/dircolors.c (dc_parse_stream): Support globbing of TERM entries, to allow entries like "TERM *256color*" for example. * src/dircolors.hin: Reduce the internal list with globbing. * tests/misc/dircolors.pl: New test cases. * NEWS: Mention the improvement.
2015-10-10tests: make a long running test responsive to Ctrl-CPádraig Brady
* tests/misc/sort-compress-hang.sh: Use --foreground with the timeout(1) command (noting the caveats), to run the sort command in the foreground program group, and thus be responsive to Ctrl-C. This very_expensive_ test takes over a minute on a i3-2310M, with RAM backed /tmp.
2015-10-08tests: adjust recent changes to virtual memory limitsPádraig Brady
* tests/dd/no-allocate.sh: Account for timeout(1) when determining the required mem, as timeout has additional shared libs. This avoids the need for the hardcoded 4M addition to the limit. * tests/misc/head-c.sh: Increase the base limit, to account for the fact that head(1) will allocate some additional mem in this case. * tests/misc/cut-huge-range.sh: Remove mention of specific limits. * tests/misc/printf-surprise.sh: Likewise. Reported by Dmitry V. Levin
2015-10-06csplit: remove erroneous mention of -m in --helpPádraig Brady
* src/csplit.c (usage): -m is not accepted, only --suppress-matched. * tests/misc/csplit-suppress-matched.pl: Spelling fix. Reported by Ondrej Oprala
2015-09-22maint: use adaptive approach for `ulimit -v` based testsBernhard Voelker
When configured with either 'symlinks' or 'shebangs' as value for the --enable-single-binary option, tests based on `ulimit -v` are skipped. The reason is that the multicall 'coreutils' binary requires much more memory due to shared libraries being loaded, and the size of the 'date' binary (~290KiB) compared to the multicall binary (~5MiB), of course. Finally, in the case of 'shebangs', the starting shell requires more memory, too Instead of using hard-coded values for the memory limit, use an adaptive approach: first determine the amount of memory for a similar, yet more trivial invocation of the command, and then do the real test run using that limit (plus some buffer in some cases). * init.cfg (require_ulimit_v_): Remove function. (get_min_ulimit_v_): Add function to determine the minimum memory limit required for a given command in an adaptive way. * cfg.mk (sc_prohibit_test_ulimit_without_require_): Change the name of the above function in the syntax-check rule. * tests/cp/link-heap.sh: Use the above function to determine the minimum memory required to run a command simpler than in the real test run. Use that limit plus a buffer there. While at it, change to list of commands in the subshell to fail also if the beginning `ulimit -v` fails. * tests/dd/no-allocate.sh: Likewise. * tests/misc/csplit-heap.sh: Likewise. * tests/misc/cut-huge-range.sh: Likewise. * tests/misc/head-c.sh: Likewise. * tests/misc/printf-surprise.sh: Likewise. * tests/split/line-bytes.sh: Likewise. * tests/rm/many-dir-entries-vs-OOM.sh: Likewise - doing it separately for each program under test.
2015-09-22sort,numfmt: with --debug, diagnose failure to set localePádraig Brady
* src/sort.c (main): With --debug, warn upon setlocale() failure, which can happen due to incorrectly specified environment variables, or due to memory exhaustion (simulated with ulimit -v), etc. * tests/misc/sort-debug-warn.sh: Add a test case. See also http://savannah.gnu.org/bugs/11004
2015-09-12numfmt: use new set-fields module to parse --fieldAssaf Gordon
numfmt --field=LIST can accept the same options as cut. * bootstrap.conf: remove xlist, linked-list * src/local.mk: link numfmt with set-fields * src/numfmt.c: use set-fields.c instead of custom field parsing code. (include_field): adapt to new code. * tests/misc/numfmt.pl: add new tests, adapt current tests to new error message wording from set-fields.c
2015-09-12cut: refactor into set-fields moduleAssaf Gordon
Extract the functionality of parsing --field=LIST into a separate module, to be used by other programs. * src/cut.c: move field parsing code from here ... * src/set-fields.{c,h}: ... to here. (set_fields): generalize by supporting multiple parsing/reporting options. (struct range_pair): rename to field_range_pair. * src/local.mk: link cut with set-field. * po/POTFILES.in: add set-field.c * tests/misc/cut.pl: update wording of error messages
2015-09-03tests: test numfmt stdin behaviorPádraig Brady
* tests/misc/tty-eof.pl: Add numfmt to the list of programs that accept input on stdin.
2015-09-03base64: no longer support hex or oct --wrap paramsPádraig Brady
* src/base64.c (main): Support decimal numbers with leading zeros, by disabling the auto detection of octal and hex. It's not envisaged that base conversion is needed for --wrap parameters, and in the edge case it is, $((0x0)) shell constructs can be used. * tests/misc/base64.pl: Adjust accordingly. * NEWS: Mention the change in behavior.
2015-09-03base64: use stricter validation on wrap columnPádraig Brady
* src/base64.c (main): Use the higher level xnumtoumax() rather than xstrtoumax(), which is simpler and improves validation of input. Also pass the _empty_ rather than NULL string as the suffixes parameter so that invalid trailing characters are not allowed. For example -w08 is now flagged as an error, rather than being interpreted as 0. A subsequent commit will further improve verification of numbers with leading zeros by dropping backwards compatibility wrt auto parsing oct and hex numbers. * tests/misc/base64.pl: Add tests for invalid wrap values.
2015-09-03base32: A new program similar to base64Pádraig Brady
Suggested in https://bugzilla.redhat.com/1250113 * AUTHORS: Add base32. * THANKS.in: Add suggester. * README: Reference the new program. * NEWS: Mention the new program. * src/.gitignore: Ignore the new binary. * bootstrap.conf: Reference the gnulib base32 module. * build-aux/gen-lists-of-programs.sh: Add base32. * man/base32.x: A new template. * man/.gitignore: Ignore the new man page. * man/local.mk: Reference the new man page. * doc/coreutils.texi (base32 invocation): Document the new command. * src/local.mk: Adjust to build base32 based on base64.c. * src/base64.c: Parameterize to use the correct headers, functions and buffer sizes, depending on which binary is being built. * tests/misc/base64.pl: Adjust to test both base32 and base64. * tests/misc/tty-eof.pl: Add base32 as a program that accepts input on stdin without any options specified. * scripts/git-hooks/commit-msg: Add base32 to the template.

Fixes http://bugs.gnu.org/20998
2015-07-03tests: avoid side effects of $SHELL environment variablePádraig Brady
Since non interactive shells don't generally set $SHELL, its value is propagated through the tests and may cause issues; for example if $SHELL implicitly adjusts $PATH when run. Instead we set $SHELL to that determined by the posix-shell module, and use that consistently for all test sub scripts, including those created thorugh the `split --filter` command. * tests/local.mk: Explicitly set $SHELL to $(PREFERABLY_POSIX_SHELL) which defaults to $CONFIG_SHELL and thus usually /bin/sh. * tests/envvar-check: Remove bash environment variables with side effects, in case /bin/bash was selected for $SHELL. * tests/misc/help-version.sh: Remove redundant initialization of $SHELL. * tests/install/strip-program.sh: Use $SHELL for sub script. * tests/misc/sort-compress-hang.sh: Likewise. * tests/misc/sort-compress-proc.sh: Likewise. * tests/misc/sort-compress.sh: Likewise. * tests/misc/timeout-group.sh: Likewise. * tests/rm/fail-eperm.xpl: Remove redundant elision of bash env vars. * tests/misc/pwd-long.sh: Likewise.
2015-07-02tests: avoid false failures on OpenBSD 5.7Pádraig Brady
* tests/du/threshold.sh: Homogenize getopt error messages. * tests/misc/numfmt.pl: Likewise. * tests/mv/i-3.sh: Skip on *BSD not just FreeBSD.
2015-07-01tests: avoid false failure on FreeBSD systemsPádraig Brady
* tests/misc/stty.sh: FreeBSD returns ENOTTY for the TIOCEXT ioctl, so just avoid this option for now.
2015-06-25tests: avoid false failure when running as rootPádraig Brady
* tests/misc/sync.sh: Ensure dir is unreadable before including the permission check.
2015-06-24factor: avoid interspersed lines for parallel runsPádraig Brady
* src/factor.c (n_out): A new global variable to track how much data has been written to stdout. (print_factors_single): Use n_out to determine whether to flush the current (and previous) lines. * tests/misc/factor-parallel.sh: Add a new test. * tests/local.mk: Reference the new test. * NEWS: Mention the bug fix.
2015-06-24seq: handle exponents more consistentlyPádraig Brady
src/seq.c (scan_arg): Set precision and width _after_ exponentiation. For example, this will make '1.1e1 12' and '11 1.2e1' equivalent. One can still set the precision by specifying extra precision on the start value, or more naturally with a precision on a step value. * tests/misc/seq-precision.sh: Add new cases.
2015-06-24seq: use consistent output format with hex integersPádraig Brady
* src/seq.c (scan_arg): Set precision to 0 for hex constants (while avoiding hex floats). This will use then use the fast path for these arguments. Note we also set the precision of inf to 0 here, which ensures we use consistent precision on output where possible. * tests/misc/seq-precision.sh: Add corresponding test cases.
2015-06-24seq: support inf last item more generally/efficientlyPádraig Brady
* src/seq.c (main): Call seq_fast for infinite last value. This implicitly avoids format conversion on the 999999 -> 1000000 transition. * src/seq.c (seq_fast): Generalize the buffer handling, and adjust to handle the "inf" last value specifics. * tests/misc/seq-precision.sh: A new test. * tests/local.mk: Reference the new test.
2015-06-22numfmt: don't hardcode floating point limitsPádraig Brady
* src/numfmt.c (MAX_UNSCALED_DIGITS): Set this to LDBL_DIG rather than hardcoding at 18 for better portability. * tests/misc/numfmt.pl: Restrict limit tests to supported platforms.
2015-06-22numfmt: handle leading zeros correctlyPádraig Brady
* src/numfmt.c (simple_strtod_int): Don't count leading zeros as significant digits. Also have leading zeros as optional for floating point numbers. * tests/misc/numfmt.pl: Add test cases. * NEWS: Mention the fix.
2015-06-22numfmt: avoid integer overflow when roundingPádraig Brady
Due to existing limits this is usually triggered with an increased precision. We also add further restrictions to the output of increased precision numbers. * src/numfmt.c (simple_round): Avoid intmax_t overflow. (simple_strtod_int): Count digits consistently for precision loss and overflow detection. (prepare_padded_number): Include the precision when excluding numbers to output, since the precision determines the ultimate values used in the rounding scheme in double_to_human(). * tests/misc/numfmt.pl: Add previously failing test cases. * NEWS: Mention the fix.
2015-06-21numfmt: support user specified output precisionPádraig Brady
* src/numfmt.c (usage): Update the --format description to indicate precision is allowed. (parse_format_string): Parse a precision specification like the standard printf does. (double_to_human): Honor the precision in --to mode. * tests/misc/numfmt.pl: New tests. * doc/coreutils.texi (numfmt invocation): Mention the new feature. * NEWS: Likewise.
2015-06-19numfmt: implement support for field rangesDylan Cali
* src/numfmt.c: Replace field handling code with logic that understands field range specifiers. Instead of processing a single field and printing line prefix/suffix around it, process each field in the line checking whether it has been included for conversion. If so convert and print, otherwise just print the unaltered field. (extract_fields): Removed. (skip_fields): Removed. (process_line): Gutted and heavily reworked. (process_suffixed_number): FIELD is now passed as an arg instead of using a global. (parse_field_arg): New function that parses field range specifiers. (next_field): New function that returns pointers to the next field in a line. (process_field): New function that wraps the field conversion logic (include_field): New function that checks whether a field should be converted (compare_field): New function used for field value comparisons in a gl_list. (free_field): New function used for freeing field values in a gl_list. Global variable FIELD removed. New global variable all_fields indicates whether all fields should be processed. New global variable all_fields_after stores the first field of a N- style range. New global variable all_fields_before stores the last field of a -M style range. New global variable field_list stores explicitly specified fields to process (N N,M or N-M style specifiers). (usage): Document newly supported field range specifiers. * bootstrap.conf: Include xlist and linked-list modules. numfmt now uses the gl_linked_list implementation to store the field ranges. * tests/misc/numfmt.pl: Add tests for 'cut style' field ranges. Adjust existing tests as partial output can occur before an error Remove test for the 'invalid' field -5.. this is now a valid range. * gnulib: update to avoid compiler warnings in linked-list. * NEWS: Mention the new feature.
