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.
2015-11-25tests: for compare_(), use cmp -s where availablePádraig Brady
* tests/init.sh (compare_): Only fall back to cmp without the POSIX defined -s option, where this is not available.
2015-11-24copy: fix copying of extents beyond the apparent file sizeDmitry Monakhov
fallocate can allocate extents beyond EOF via FALLOC_FL_KEEP_SIZE. Where there is a gap (hole) between the extents, and EOF is within that gap, the final hole wasn't reproduced, resulting in silent data corruption in the copied file (size too small). * src/copy.c (extent_copy): Ensure we don't process extents beyond the apparent file size, since processing and allocating those is not currently supported. * tests/cp/fiemap-extents.sh: Renamed from tests/cp/fiemap-empty.sh and re-enable parts checking the extents at and beyond EOF. * tests/local.mk: Reference the renamed test. * NEWS: Mention the bug fix. Fixes http://bugs.gnu.org/21790
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
2015-11-21tests: avoid false failure on older NFS implementationsPádraig Brady
* tests/ls/stat-failed.sh: Skip the test if 'd' is returned as the type, and document where this was seen. Also flag failure to write small temp files during the test as an error rather than a failure. Fixes http://bugs.gnu.org/21130
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.
2015-11-06tests: fix dirent d_type support verificationPádraig Brady
* init.cfg (require_dirent_d_type_): Don't use df -x to exclude XFS, since this depends on a correct mtab which is brittle and often not correct within chroots. * tests/d_type-check: Check also the d_type of files, which excludes XFS appropriately. Specify all argument and return types to avoid truncated pointers being passed, which skipped the test due to crashes on x86_64 at least. Simplify the C library lookup by reusing the interpreter's. chroot issue reported at https://bugzilla.redhat.com/1263341
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
2015-10-21ls: fix off by one error when determining max display columnsPádraig Brady
* src/ls.c (main): Account for the first column not including a separator when calculating max_idx. * tests/ls/w-option.sh: Add a test case. * NEWS: Mention the bug fix.
2015-10-21ls: allow -w0 to mean no limit on line lengthPádraig Brady
* src/ls.c (print_with_separator): Renamed from print_with_commas, and parameterized to accept the separator to print. Also fix an edge case where '\n' not printed when the POS variable overflows SIZE_MAX. (print_current_files): Degenerate -x and -C to using the cheaper print_with_separator() in the -w0 case. * doc/coreutils.texi (ls invocation): Document the new feature. * tests/ls/w-option.sh: A new test. * tests/local.mk: Reference the new test. * NEWS: Mention the improvement. Fixes http://bugs.gnu.org/21325
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.
2015-10-19tests: avoid failure when auto selecting factor testsPádraig Brady
* tests/factor/run.sh: If this template is found through `grep -El "print_ver_.* factor"` for example, then just skip it.
2015-10-18maint: avoid duplicate test runsBernhard Voelker
* tests/local.mk (all_tests): Remove the tests 'tests/id/setgid.sh' and 'tests/mkdir/smack-root.sh' because they are mentioned in the 'all_root_tests' list; these tests are skipped anyway during a non-root run because flagged with 'require_root_'.
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.
2015-10-15tests: avoid false failure in rm/r-root.sh with gdb warningsPádraig Brady
* tests/rm/r-root.sh: Skip the test if there are gdb warnings that will impact further stderr checks. For example some buggy gdb versions may report "Got object file from memory but can't read symbols: File truncated". Also fix an incorrect stderr check from the previous change. Reported by Bernhard Voelker.
2015-10-15tests: avoid false failure in rm/r-root.sh under loadPádraig Brady
* tests/rm/r-root.sh: Use gdb rather than timeout(1) as the last resort protection against unlinkat() calls. The timeout of 2s was susceptible to false positives under load, and gdb is stronger protection in any case. We remove the "expensive" tag on this test also since it should be robust. Reported by Jim Meyering.
2015-10-15tests: avoid false failure in a tail test under loadPádraig Brady
* tests/tail-2/follow-stdin.sh: Use the standard tail testing framework to avoid the race seen under very high load, and also test the non inotify case. Reported by Jim Meyering
2015-10-14tests: avoid false failures with default ACLsPádraig Brady
To reproduce: setfacl -dm group::rx . setfacl -dm other::rx . make check * init.cfg (require_no_default_acl_): A new function to skip when default ACLs are detected, or if the getfacl utility is not available then skip if any non LSM ACLs detected. * tests/cp/existing-perm-race.sh: Call require_no_default_acl_. * tests/mkdir/parents.sh: Likewise. * tests/mkdir/perm.sh: Likewise.
2015-10-10tests: avoid false failure when restorecon is ineffectivePádraig Brady
* tests/cp/cp-a-selinux.sh: Ensure we skip the portion of the test depending on restorecon to be effective. I.E. also skip when restorecon warns, as it doesn't exit with error status when matchpathcon fails to find a match for a file. This is the case in /tmp on Fedora for example, in which case the new destination that cp creates will have the default security context of the process, rather than the explicit context we set on the source file. Details at: http://bugzilla.redhat.com/1247641
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.
2015-08-30tests: avoid FP of ls/stat-free-color.sh with newer glibcBernhard Voelker
Since glibc-2.22, specifically commit [0], the opendir() implementation implicitly makes an additional stat call thus leading to a FP. Seen on openSUSE:Tumbleweed since snapshot 20150821. [0] https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=46f894d8c60a * tests/ls/stat-free-color.sh: Change the test to verify that ls(1) needs the same number of stat-like calls for a single, empty directory argument as for one with a few directory entries (sub-directory, regular file, symlink, etc.).

2015-07-03tests: update gnulib submodule and tests/init.sh to latestPádraig Brady
* gnulib: Update to latest, with fixes to tests edge cases. * tests/init.sh: Update from gnulib.
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.
