link,ln: use gnulib's link module to work around Solaris 10 deficiency

2009-09-10T16:52:12Z

Before this change, :>f; ln -T f no-such/ would succeed on Solaris 10. After it, ln fails, as it should: ln: accessing `z/': Not a directory The command, link f no-such/, had the same problem on that system. * bootstrap.conf (gnulib_modules): Add "link". * tests/ln/slash-decorated-nonexistent-dest: New test. * tests/Makefile.am (TESTS): Add it. * NEWS (Portability): Mention the improvement.

dd conv=unblock: print final newline consistently

2009-09-10T10:25:04Z

* src/dd.c (dd_copy) [C_UNBLOCK]: Always print the final newline for non-empty output, not just when output size is a multiple of cbs. * doc/coreutils.texi (dd invocation) [conv=unblock]: Mention that dd prints a newline after each output record, not just when replacing trailing spaces. Reported by Ulrich Drepper. * tests/dd/unblock: New file. Test for this. * tests/Makefile.am (TESTS): Add it. * NEWS (Bug fixes): Mention it.

tests: tail-2/assert: reduce risk of race condition

2009-09-08T09:01:45Z

* tests/tail2/assert: This reverts commit be853120, 25-08-2009, "tests: tail-2/assert: avoid risk of race condition" kill -0 doesn't send a signal and so will only confirm that the background process was forked, which we know already because we have its pid.

tests: address a race condition in misc/cat-buf

2009-09-08T00:43:31Z

* tests/misc/cat-buf: Increase the delay between writes to decrease the chance that dd will read both at once. Since the test is inherently racy, print a warning via skip_test_ rather than failing outright. Reported by Jim Meyering.

tail: ignore -f for piped-stdin, as POSIX requires

2009-09-07T21:19:56Z

* src/tail.c (main): Tailing a pipe "forever" is not useful, and POSIX specifies that tail ignore the -f when there is no file argument and stdin is a FIFO or pipe. So we do that. In addition, GNU tail excludes "-" arguments from the list of files to tail forever, when the associated file descriptor is connected to a FIFO or pipe. Before this change, ":|tail -f" would hang. Reported by Ren Yang and Ulrich Drepper. * tests/tail-2/pipe-f: Test for this. * tests/tail-2/pipe-f2: Ensure tail doesn't exit early for a fifo. * tests/Makefile.am (TESTS): Add these tests. * NEWS (POSIX conformance): Mention it.

tests: tail-2/flush-initial should not rely on stdbuf

2009-09-07T20:52:30Z

* tests/tail-2/flush-initial: stdbuf is not built on all systems. In any case it's redundant since stdout will automatically be buffered since we're redirecting to file. So just call tail without using stdbuf.

tests: misc/cat-buf: clean up syntax

2009-09-07T18:23:03Z

* tests/misc/cat-buf: Don't suppress dd's stderr. Remove useless quotes.

tests: ls/color-clear-to-eol: append NL to accommodate old sed

2009-09-07T17:36:37Z

* tests/ls/color-clear-to-eol: Some vendor sed programs fail to operate on lines that are not NL-terminated. This affects at least Solaris 10's /bin/sed. Reported by Pádraig Brady.

tests: tail-2/infloop-1: avoid rare test failure on a busy system

2009-09-07T11:55:37Z

* tests/tail-2/infloop-1: Sleep 3 seconds, not 1, but in increments of 0.1 second. Before, this test would fail ~1 time in 20 via "make -j9 check" on a quad-core system. Correct comment.

tail -f: handle "-"/stdin once again

2009-09-07T07:01:14Z

* src/tail.c (main) [HAVE_INOTIFY]: When stdin (i.e., "-", or no args, but not /dev/stdin) is specified on the command line, don't use inotify. Reported by Bill Brelsford in . * tests/tail-2/follow-stdin: New file. Test for this. * tests/Makefile.am (TESTS): Add the test. * NEWS (Bug fixes): Mention it. This bug was introduced in coreutils-7.5 via commit ae494d4b, 2009-06-02, "tail: use inotify if it is available".
