tests: fix false failure with spaces in $PWD

2016-11-30T15:50:59Z

* tests/misc/ptx-overrun.sh: Quote appropriately to avoid this recently added issue, noticed by `make taint-distcheck`.

tests: fix ERRORs and false FAILs on some platforms

2016-11-29T21:21:12Z

* tests/misc/ls-time.sh: Skip the test rather than ERROR when `touch -m -d ...` fails (Hurd). * tests/tail-2/follow-stdin.sh: Avoid false FAILs by ignoring the variances in sterror output. * tests/rm/rm-readdir-fail.sh: Likewise. Also avoid ERRORs on systems that don't define _D_EXACT_NAMELEN.

tac: fix mem corruption when failing to read non seekable inputs

2016-11-28T13:19:24Z

This was detected with ASAN, but can also be seen without ASAN with: $ tac - - <&- tac: standard input: read error: Bad file descriptor *** Error in `tac': malloc(): memory corruption: 0x... * src/tac.c (copy_to_temp): Don't close our output stream on (possibly transient) output error, or on input error. (temp_stream): clearerr() on the stream about to be reused, to ensure future stream use is not impacted by transient errors. * tests/misc/tac-2-nonseekable.sh: Add a test case. * NEWS: Mention the bug fix. Fixes http://bugs.gnu.org/25041

doc: add NEWS entries for recent changes

2016-11-27T01:20:09Z

* NEWS: Mention in improvements about the workaround for the glibc issue with closed stdin, and the new supported file systems. * tests/misc/b2sum.sh: Spelling fix.

shuf: test input-closed bug

2016-11-26T23:38:08Z

Problem reported by Alex Ryan (Bug#25029). * tests/misc/shuf.sh: Test for shuffling with stdin closed.

ptx: fix an invalid heap reference with short --width

2016-11-24T16:21:59Z

* src/ptx.c (fix_output_parameters): Ensure line_width doesn't go negative, which can happen when the --width is less than the --gap-size. * tests/misc/ptx-overrun.sh: Add a test case that triggers with ASAN. (Note the longer filename is needed to trigger). Fixes http://bugs.gnu.org/25011

comm: add --total option

2016-11-22T21:03:47Z

* src/comm.c (total_option): Add bool variable for the new option. (TOTAL_OPTION): Add enum value. (long_options): Add array element for the new option. (usage): Document the new option here. (compare_files): Count the lines in total[3], and output the summary at the end. (main): Accept the new option. * doc/coreutils.texi (comm invocation): Document it. * tests/misc/comm.pl: Test it. While at it, improve the test data to have 1 unique line in the first file, 2 unique lines in the second file, and 3 common lines. * NEWS (New Features): Mention the new option. Fixes http://bugs.gnu.org/24929

tests: fix false failure with FreeBSD 11 multibyte quoting

2016-11-22T20:04:25Z

* tests/misc/printf-quote.sh: FreeBSD 11 was seen to treat \u0378 as a printable character. Therefore change to using the \u0081 C1 control character. We use the UTF-8 representation because our printf implementation explicitly disallows \u0081 as input. Reported by Assaf Gordon

tests: fix false fails due to passing env vars to returns_

2016-11-22T20:04:25Z

On BSD /bin/sh it was seen that unexported env vars passed to returns_() would not be propagated to the wrapped command. * cfg.mk (sc_prohibit_env_returns): Add a syntax check to disallow. * tests/misc/csplit-io-err.sh: Rearrange to export vars in a subshell. * tests/rm/rm-readdir-fail.sh: Likewise. * tests/misc/nohup.sh: Export and unset vars around returns_. * tests/misc/printenv.sh: Likewise. Reported by Assaf Gordon

b2sum: a new checksum utility with md5sum like interface

2016-11-22T20:04:24Z

Note we don't support the --algorithm option of the b2sum command in the external BLAKE2 project, as that was deemed too confusing for users. "BLAKE2b" was chosen as the default algorithm to use, which is single threaded but performs well on 64 bit. * src/blake2: CC0 source copied from external project. * cfg.mk[VC_LIST_ALWAYS_EXCLUDE_REGEX]: Exclude blake2/ from syntax checks, make update-copyright, etc. * src/local.mk: Reference the sources for b2sum, and set the compilation flags. * doc/coreutils.texi (b2sum invocation): Reference the md5sum invocation node, and add descriptions of -l. * tests/misc/b2sum.sh: Add new test. * tests/local.mk: Reference new test. * AUTHORS: Add new binary. * README: Likewise. * build-aux/gen-lists-of-programs.sh: Likewise. * man/.gitignore: Likewise. * scripts/git-hooks/commit-msg: Likewise. * man/b2sum.x: New man page template. * man/local.mk: Reference new template. * src/.gitignore: Ignore new binaries. * src/blake2/.gitignore: Ignore new build atrifacts. * src/md5sum.c (usage): Describe the new -l option. * NEWS: Mention the new program.
