2016-01-18tests: adjust memory limits in head-c.shAssaf Gordon
* tests/misc/head-c.sh: Further increase the limit to 8MB over the base test command. 5.1MB was seen as minimum extra needed on FreeBSD 9.3 x86_64.
2016-01-18tests: adjust delays to avoid false positivesPádraig Brady
* tests/rm/dangling-symlink.sh: The effective delay was only 1.5s. So delay before the operation, and increase the iteration count by 1 to increase the delay to 6.3s. This failure was noticed once on a FreeBSD 10.2 x86_64 virtual machine. * tests/dd/stats.sh: Remove quotes on sleep argument to ensure arguments are accumulated appropriately. * tests/du/move-dir-while-traversing.sh: sleep before operation, to increase the effective delay from 1.6s to 3.2s. * tests/tail-2/flush-initial.sh: Likewise. * tests/tail-2/pipe-f2.sh: Sleep first so that the effective delay matches the commented value.
2016-01-18test: skip test rather than fail with Solaris 10 sedPádraig Brady
* tests/rm/r-root.sh: This test was seen to ERROR due to sed input not having a terminating '\n'. Therefore just skip with diagnostics upon failure to adjust the error output with sed. Reported by Assaf Gordon.
2016-01-16tests: fix false failure with spaces in absolute $PWDPádraig Brady
* tests/install/create-leading.sh: Ensure $PWD is quoted. Reported by `make dist-check`.
2016-01-16tests: show mount list on failure for df testsPádraig Brady
* init.cfg (dump_mount_list_): A new function to output the system mount list. * tests/df/df-symlink.sh: Call dump_mount_list_ upon failure. * tests/df/over-mount-device.sh: Likewise. * tests/df/problematic-chars.sh: Likewise. * tests/df/skip-rootfs.sh: Likewise. * tests/df/total-verify.sh: Likewise. * tests/df/unreadable.sh: Likewise.
2016-01-16tests: avoid false failure with BTRFS subvolumesPádraig Brady
* tests/df/df-symlink.sh: Only check the symmetry of the source <-> target lookup, when the source is only mounted once, which isn't the case if '.' is a BTRFS subvolume for example. Reported by Assaf Gordon on a default OpenSUSE 42.1 install.
2016-01-15tests: remove a non portable localtime testPádraig Brady
* tests/misc/date.pl: This test was dependent on perl unconditionally calling the system localtime() as date(1) does. However perl has its own configure checks in place to avoid buggy localtime implementations. Therefore comment out this test as a FIXME for now. This test was seen to fail on FreeBSD 10 where localtime() returns nonsense values instead of failing for arguments >= 2^56.
2016-01-15tests: adjust memory limits in head-c.shPádraig Brady
* tests/misc/head-c.sh: Further increase the limit, to account for the fact that head(1) needs at least 1.576MB over the base test command on FreeBSD 10. 4MB should be enough headroom while still providing over allocation protection. Reported by Assaf Gordon.
2016-01-15tests: simplify invalid signal determination for kill -lPádraig Brady
* src/operand2sig.c (operand2sig): Add a detailed comment explaining why we validate even very large shell exit status values. * tests/misc/kill.sh: Add a test case for the ksh scheme. Simplify the INVALID signal number determination which also avoids a false failure on systems like FreeBSD 10 with incomplete signal list (caused by inaccurate NSIG).
2016-01-15tests: support older fallocate number formatsPádraig Brady
* tests/cp/fiemap-extents.sh: Support RHEL6 fallocate which doesn't support IEC suffixes like "MiB" on numbers. Also add some extra framework_failure_ protections. Reported by Assaf Gordon.
2016-01-13mv: fix data loss with repeated source dir and same destinationPádraig Brady
commit v8.23-31-g90aa291 failed to consider this case, where the previous rename has failed, thus causing the following to remove the specified directory: mv dir dir dir * src/copy.c (copy_internal): Assume this rename attempt has succeeded, as a previous failure will already have been handled, and we don't want to remove the source directory in this case. * tests/cp/duplicate-sources.sh: Consolidate this test file to... * tests/mv/dup-source.sh: ...here. Add test cases for same source and dest. * tests/local.mk: Remove the consolidated test. * NEWS: Mention the bug fix. Reported at https://bugzilla.redhat.com/1297464
2016-01-13tests: include part of wc-files0.sh skipped by mistakePádraig Brady
* tests/misc/wc-files0.sh: $fail is always set to 0, so correct the test to include that part of the test case.
2016-01-13wc: avoid ambiguous output with '\n' in file namesPádraig Brady
* src/wc.c (write_counts): Shell escape the file name if it contains '\n' so only a single line per file is output. * tests/misc/wc-files0.sh: Add a test case. * NEWS: Mention the improvement.
2016-01-13numfmt: add the -z,--zero-terminated optionAssaf Gordon
* doc/coreutils.texi (numfmt invocation): Reference the description. * src/numfmt.c: Parameterize '\n' references. * tests/misc/numfmt.pl: Add tests for character and field processing. * NEWS: Mention the new feature.
2016-01-13paste: add the -z,--zero-terminated optionPádraig Brady
* doc/coreutils.texi (paste invocation): Reference -z description. * src/paste.c (main): Parameterize the use of '\n'. * tests/misc/paste.pl: Add test cases. * NEWS: Mention the new feature.
2016-01-13comm: support NUL --output-delimiter for consistencyPádraig Brady
* src/comm.c (main): Track the output delimiter length, so that it can be adjusted to 1 for the NUL delimiter. Also rename the global variable from "delimiter" to "col_sep" so its use is more obvious, and to distinguish from the recently added "delim" global variable. * tests/misc/comm.pl: Adjust accordingly.
2016-01-13comm: add the -z,--zero-terminated optionPádraig Brady
* doc/coreutils.texi (comm invocation): Reference option description. * src/comm.c (main): Use readlinebuffer_delim() to support a parameterized delimiter. * tests/misc/comm.pl: Add test cases. * NEWS: Mention the new feature.
2016-01-13tac: support an empty (NUL) --separatorPádraig Brady

2016-01-13cut: add the -z,--zero-terminated optionPádraig Brady
* doc/coreutils.texi (cut invocation): Reference the description. * src/cut.c: Parameterize '\n' references. * tests/misc/cut.pl: Add tests for character and field processing. * NEWS: Mention the new feature.
2016-01-13head,tail: add the -z,--zero-terminated optionRichard Russon
* doc/coreutils.texi: Reference the option description. * src/head.c: Parameterize the delimiter character. * src/tail.c: Likewise. * tests/misc/head.pl: Add test case. * tests/misc/tail.pl: Likewise. * NEWS: Mention the new feature.
2016-01-13join,sort,uniq: with -z, treat '\n' as a field separatorPádraig Brady
* NEWS: Mention the change in behavior. * doc/coreutils.texi (newlineFieldSeparator): A new description, referenced from ({join,sort,uniq} invocation). * src/system.h (field_sep): A new inline function to determine if a character is a field separator. * src/join.c (usage): s/whitespace/blank/ to be more accurate wrt which characters are field separators. (xfields): s/isblank/field_sep/. * src/sort.c (inittables): Likewise. * src/uniq.c (find_field): Likewise. * tests/misc/join.pl: Adjust -z test, and add a test/example for processing the whole record with field processing. * tests/misc/sort.pl: Add -z test cases, including case with '\n'. * tests/misc/uniq.pl: Add -z -f test case with \n.
2016-01-10tests: fix races wrt output files of background processesBernhard Voelker
At least the false positive in tail-2/follow-stdin.sh could be seen on a 4-core i5 system with -j8. Fix similar cases. too. * tests/tail-2/follow-stdin.sh: Empty the 'out' file in each iteration. Otherwise, under heavy system load, 'check_tail_output' would see the expected output from the previous round before tail would have the chance to come up in the background. While at it, move the creation of the 'exp' file out of the loop. * tests/dd/stats.sh: Empty the output file of the background process here, too. * tests/misc/cat-buf.sh: Likewise. * tests/misc/stdbuf.sh: Likewise. * tests/tail-2/wait.sh: Likewise.
2016-01-06stty: support [-]drain setting to control waiting for pending TxPádraig Brady
Instead of commit v8.24-132-g5171bef which only provides control to disable this behavior (with -I), provide the symmetrical "[-]drain" special setting. * src/stty.c (main): Parse the [-]drain setting instead of -I, and treat like a global option. (usage): Adjust accordingly. * tests/misc/stty.sh: Test "drain" with and without options. * NEWS: Mention the new feature.
2016-01-04stty: support -I, --immediate to not wait for pending transmissionPádraig Brady
In some cases an initial drain may block indefinitely as discussed at: http://lists.gnu.org/archive/html/coreutils/2016-01/msg00007.html * src/stty.c (main): Use TCSANOW rather than TCSADRAIN if -I specified. (usage): Document the new option. * doc/coreutils.texi (stty invocation): Likewise. * tests/misc/stty.sh: Ensure -I is supported. * NEWS: Mention the new feature.
2016-01-03install: fix relative copies to absolute directory with -DPádraig Brady
* src/install.c (mkancesdirs_safe_wd): Unconditionally restore the current working directory when possibly called multiple times (from install_file_in_dir()). * tests/install/create-leading.sh: Add a test case. * NEWS: Mention the fix. Fixes http://bugs.gnu.org/21497
2016-01-01maint: update all copyright year number rangesPádraig Brady
Run "make update-copyright" and then... * gnulib: Update to latest with copyright year adjusted. * tests/init.sh: Sync with gnulib to pick up copyright year. * bootstrap: Likewise. * tests/sample-test: Adjust to use the single most recent year.
2015-12-31dd: summarize in --human-readable format tooPaul Eggert
Problem reported by Linda Walsh in: http://bugs.gnu.org/17505 * NEWS: Document this. * doc/coreutils.texi (dd invocation): Use a simpler script. Adjust output example to match new behavior. * src/dd.c (human_size): Remove. All uses changed to use human_readable and ... (human_opts): ... this new constant. (abbreviation_lacks_prefix): New function. (print_xfer_stats): Use it. Output both --si and --human-readable summaries, but only if they have prefixes. * tests/dd/reblock.sh, tests/dd/stats.sh: Test new behavior.
2015-12-17tests: avoid root test false failure without libxattrPádraig Brady
* tests/cp/cp-mv-enotsup-xattr.sh: Exclude xattr copy verification when libxattr is not available.
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.
2015-11-25tests: 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.
