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.

tail: make the new piped-stdin test as portable as the old one

2009-09-08T11:30:38Z

* src/tail.c (main): Adapt piped-stdin test to use the same isapipe, test as was used in the preceding POSIXLY_CORRECT condition. Remove the now-subsumed POSIXLY_CORRECT test. Reported by Pádraig Brady. * doc/coreutils.texi (tail invocation): Document this change. * NEWS (Changes in behavior): Reclassify, clarify.

tail: syntax-only: use "false", rather than equivalent, 0

2009-09-07T21:20:01Z

* src/tail.c (record_open_fd): Initialize "->ignore" to false, not 0.

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.

tail: don't give up on inotify mode for an already-ignored "-"

2009-09-07T18:56:38Z

* src/tail.c (main): Adjust today's change to honor the F[i].ignore flag that may have been set in tail_file.

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".

tail: flush initial output before possibly blocking

2009-09-06T07:40:43Z

* src/tail.c (main): Flush any output from tail_file, before calling tail_forever_inotify, which can block. * tests/tail-2/flush-initial: New file. Test for the bug. * tests/Makefile.am (TESTS): Add tail-2/flush-initial. * 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".

doc: make the tail --sleep-interval help less confusing

2009-09-05T16:25:40Z

* src/tail.c (usage): I read "approximately S seconds" as "approximately 5 seconds" for approximately 5 seconds.

maint: remove some tab indentation from copy.c

2009-09-05T16:22:09Z

* src/copy.c (copy_internal): Remove tabs erroneously added in commit 3346c0af.
