Previously passing an empty parameter to -t would
raise an error, but now it means to treat each line
as a single field for matching. This matches the
default operation of `sort` which is usually used
in conjunction with join.
* src/join.c (main): Set the field delimiter to '\n' if
an empty parameter is passed to -t.
(usage): Mention the operation of -t ''.
* tests/misc/join: Add 2 new tests, for the existing -t '\0'
and the new -t '' functionality.
* doc/coreutils.texi (join invocation): Mention that
join -t '' always operates on the whole line, while
join -t '\0' usually does.
* NEWS: Mention the change in behavior.

This essentially allows one to use --check-order with headings.
Note join without --check-order will already handle the common case
where headings do match in each file, however using --check-order will fail
often when the header sorts after the first line of data.
Note also that this will join header lines from each file even if
they don't match, with headings from the first file being used.
* NEWS: Mention the new option.
* doc/coreutils.texi (join invocation): Describe the new option.
* src/join.c (usage): Likewise.
(join): Join the header lines unconditionally.
* tests/misc/join: Add 5 new tests.
|
|
* src/join.c (join): Refactor the code that checks for misorder
at the tail of the files. The most significant change here is
that freeline() is called thus silencing a valgrind warning about
a definite but inconsequential memory leak.
(freeline): Make more general by doing nothing when passed NULL,
and setting freed pointers to NULL.

* src/ls.c (main): With --color, avoid emitting the final color-
resetting escape sequence when it would be a no-op.
* tests/ls/color-clear-to-eol: Adjust expected output accordingly.
* tests/ls/color-dtype-dir: Likewise.
* tests/ls/multihardlink: Likewise.
* tests/ls/stat-free-symlinks: Likewise.

C de-Avillez rebased and adapted four of the new sl-dangle*
tests in tests/misc/ls-misc.

Enabled when coreutils is configured with --with-tty-group.
Based on a patch written by Piotr Gackiewicz. Details at
http://bugzilla.redhat.com/454261
* src/who.c (is_tty_writable): A new function returning true if a TTY
device is writable by the group. Additionally it checks the group to be
the same as TTY_GROUP_NAME when compiled with --with-tty-group.
* m4/jm-macros.m4: Introduce a new configure option --with-tty-group.
* NEWS: Mention the change.

* src/libstdbuf.c (apply_mode): Don't leak "buf" upon setvbuf failure.
|
|
* src/pr.c (init_store_cols): Allocate N*sizeof(*VAR) bytes,
not N*sizeof(int*). The latter would mistakenly allocate double
the required space on a system with 8-byte pointers.
|
|
* src/ls.c: Include <sys/capability.h> later, to avoid build
failure with a header from libcap-2.16-1 or earlier.
See http://bugzilla.redhat.com/483548 for details.

Before this change, with too long a file name, the name would
abut the date field on the left and possibly also the "Page N"
field on the right, rather than leaving a one-space separator
in each case. Fixes a regression introduced on Mar 6 2009,
by commit a4053c5291d5797734b3e4f042f9e1adf3944fd6
* src/pr.c (print_header): Ensure that there is at least one
space before and after the file name part of the header line.
* NEWS: Mention it.
* tests/pr/W20l24f-ll: s/xPage/ x Page/.
* THANKS: Update.

* src/tac.c (main): Free the input buffer in most cases.
|
|
* src/cp.c (make_dir_parents_private): Use "||" rather than "|",
so that clang understands there is no undefined pointer dereference.
|
|
* src/ls.c (print_color_indicator): When using 'LINK target' in
dircolors, treat broken symlink as C_ORPHAN.
* tests/misc/ls-misc (sl-dangle2, sl-dangle3, sl-dangle4)
(sl-dangle5): Test for it, and add more coverage.
* NEWS: Document it.
* THANKS: Update.

* src/df.c (print_header): Use fputs rather than printf in more places.
Suggested by Eric Blake.
|
|
Use this command:
git ls-files | grep -v COPYING \
| xargs env UPDATE_COPYRIGHT_USE_INTERVALS=1 \
build-aux/update-copyright
|
|
* src/pr.c (usage): Add missing space.
|
|
* src/pr.c (usage): Move the newline character a bit farther.
|
|
* src/df.c (print_header): Add a comment telling translators to
retain the message length, and another to align header translations.
|
|
* src/tail.c (usage): Reword tail -F description, so that it no
longer mentions details specific to the non-inotify implementation.
Also, join diagnostic strings (while staying under the 509-byte limit)
to ease formatting of translations. The latter was prompted by
a report from Stéphane Raimbault.
* doc/coreutils.texi (tail invocation): Update description here, too.
|
|
This fixes a bug whereby tail -F would fail to track changes
to a file that was a target of a rename, and when the source of
the rename was another tailed file.
* src/tail.c (tail_forever_inotify): Ensure the wd is not already
present in the hash table before trying to add it. When a new watch
descriptor is added to the `wd_to_name' hash table, check that it is
not already present. If it is present then remove the previous element.
|
|
* src/tail.c (tail_forever_inotify): Avoid modifying fdspec->wd while
it is in the wd_to_name hash table. Once it is removed, it can be
added using the new `wd' as key for the hash table. This fixes the
abort-inducing bug reported by Rob Wortman in
http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/19372
|
|
* src/tail.c (tail_forever_inotify): s/wd_table/wd_to_name/
|
|
* src/tail.c (tail_forever_inotify): Do not use f[i] in a context
where i may be larger than the largest valid index. In the final
"if" clause in which we'd remove an inotify watch, we might have
used f[n_files]. Use fspec instead, since it is guaranteed to
be defined.
|
|
* src/Makefile.am (tac_LDADD): Add LIB_GETHRXTIME.
* THANKS: Update.
Reported by Robert Schwebel.

* tail.c (struct File_spec): Rearrange struct members to decrease
size by 8 bytes to 76,96 on i686,x86_64 respectively.
|
|
* src/tail.c (fremote): Add a comment.
Move definition "up" to precede first use, so we can
remove its prototype and the #if..#endif around each use.
(any_remote_file): Rename from any_remote_files.
|
|
* src/tail.c (struct File_spec): Add a flag to record if file is remote.
(recheck): If we're using inotify then check if the file has gone remote
and if so, drop it with a warning.
(any_remote_files): A new function to check for any open remote files.
(tailable_stdin): A new function to refactor the check for whether
a tailable file was specified through stdin.
(fremote): A new function to check if a file descriptor
refers to a remote file.
(tail_forever_inotify): Add some comments.
(tail_file): Record if a file is remote when initially opened.
(main): Disable inotify if any remote files specified.
Also document the caveat about remounted files not
being noticed by inotify.
* NEWS: Mention the fix.

* src/wc.c (main): Set stdout to line buffered mode
to ensure parallel running instances don't intersperse
their output. This adds 6.5% to the run time in the worst case
of many zero length files, but has neglible impact for
standard sized files.
* tests/misc/wc-parallel: New test for atomic output.
* tests/Makefile.am: Reference it.

This bug showed up via valgrind as a "Conditional jump or move
depends on uninitialized value(s)" error.
* src/tail.c (ignore_fifo_and_pipe): New function.
(main): Use it only when tailing forever.
The code to compute n_viable and mark some F[i] as ignored would call
isapipe on an uninitialized file descriptor. But n_viable and those
.ignored marks are useful/used only when tailing forever. This bug
was introduced via commit f0ff8c73 (7.6), "tail: make the new
piped-stdin test as portable as the old one".
* NEWS (Bug fixes): Mention it.

* src/sort.c (main): Reset the SIGCHLD handler to the default
as otherwise wait() could return an error.
* tests/misc/sort-compress: Set the CHLD handler in a subshell
to SIG_IGN to ensure the sort command resets it to SIG_DFL.
* NEWS: Mention the fix.
|
|
* src/timeout.c (main): Reset the SIGCHLD handler to the default
as otherwise wait() could return -1 and set errno to ECHILD.
This condition was ignored until commit 0b1dcf33, on 31-08-2009,
"timeout: defensive handling of all wait() errors"
but subsequently timeout would run the command correctly
but then fail with an error message.
* tests/misc/timeout: In a subshell set the CHLD handler to
SIG_IGN to ensure the timeout command resets it to SIG_DFL.
* NEWS: Mention the fix.

If getgroups failed with ENOSYS, mgetgroups would unnecessarily
fail, and that provoked id into freeing an uninitialized pointer.
Meanwhile, we were not using xalloc_die properly. Both issues
are better solved in gnulib, by introducing xgetgroups; this
patch uses the new interface.
Regression introduced by commit 6a31fd8d7.
* gnulib: Update, for mgetgroups improvments.
* src/id.c (print_full_info): Adjust caller to die on allocation
failure, and no longer worry about ENOSYS.
* src/group-list.c (print_group_list): Likewise.
* src/setuidgid.c (main): Likewise.
* NEWS: Mention the fix.
* THANKS: Update.

Cygwin 1.5 has a broken sleep, and the gnulib tests dragged in
rpl_sleep which then caused a link failure because it wasn't in
libcoreutils.a. We could solve it by using the gnulib sleep module.
However, sleep and usleep may interact poorly with SIGALRM, and they
have less granularity; so it is better to adopt a policy that if we
must sleep, prefer xnanosleep.
* src/sort.c (pipe_fork): Use xnanosleep, to avoid the need for
rpl_sleep on cygwin, and to reduce granularity.
(MAX_FORK_TRIES_COMPRESS, MAX_FORK_TRIES_DECOMPRESS): Increase,
to account for reduction in granularity.
* src/tail.c (tail_file): Use xnanosleep in debug code.
* cfg.mk (sc_prohibit_sleep): New rule.
|
|
* src/true.c (main): There is no reason to examine argv[0],
call atexit, etc., in the usual case in which we're about to exit.
This has the side effect of making it so that these programs
no longer segfault when subjected to execve abuse.
Before this change, these commands would make "true" segfault:
printf '%s\n' '#include <unistd.h>' 'int main(int c, char**v)' \
'{ execve (v[1], 0, 0); }' > k.c && gcc k.c && ./a.out $PWD/true
Now it succeeds. Reported by Tetsuo Handa and Bart Van Assche

Tailing forever and by-name (--follow=name, -F), tail would
sometimes fail to follow a file that had been removed via rename.
If you can't apply this patch and have tail 7.6 or newer, you can
work around the bug via the undocumented --disable-inotify option.
* src/tail.c (tail_forever_inotify): When tailing by name (-F),
do not un-watch a file upon receipt of the IN_MOVE_SELF event.
Reported by Arjan Opmeer in http://bugs.debian.org/548439.
* NEWS (Bug fixes): Mention it.
Also see http://marc.info/?l=coreutils-bug&m=125829031916515

A replacement getgroups is now guaranteed to exist, but it may
fail with ENOSYS. mgetgroups is moved to gnulib, and now takes
gid_t instead of GETGROUPS_T (but setgroups still needs GETGROUPS_T).

Capability checking was incorrectly done on just the base name
rather than on the whole path. Consequently there could be both
false positives and negatives when coloring files with capabilities.
Also capability checking was not done at all in certain cases for
non executable files. Note passing absolute rather than relative
names to cap_get_file() reduces the has_capability() overhead
from around 33% to 30%. I.E. ls --color is now around 3% faster.
* src/ls.c (struct fileinfo): Add a has_capability member.
(print_color_indicator): Refactor to pass just a fileinfo pointer
and a flag to say if we're dealing with a symlink target.
(print_name_with_quoting): Likewise.
(gobble_file): Set has_capability in the fileinfo struct. Also do
a capability check even if executable coloring is disabled.
Ditto for SETUID and SETUID coloring.
Comment on how expensive has_capability() is.
(print_long_format): Adjust to refactored print_name_with_quoting.
(quote_name): Likewise.
(print_file_name_and_frills): Likewise.

* THANKS: Add reporter (Ivan Labath).
* NEWS: Mention the fix.

cat, head, ptx, shuf, tac, tail, tee, tr, and uniq used freopen
