(all_programs.list): New rule, copied from
man/Makefile.am and tests/Makefile.am, except that we use the
system tr rather than ./tr and we don't use tr -s.

(remove_entry): Check for errno values like ENOENT
that show the file cannot be directory, instead of for errno
values like EPERM that show the file might be a directory. This
is necessary because, when a single unlink() call has multiple
reasons to fail, it can set errno to any of those reasons; it's
only the rare errno value like ENOENT that excludes all the other
possible reasons to fail even when the file is a directory.
(remove_cwd_entries): Don't attempt chdir if the file is known
to not be a directory.
(remove_dir): Use the same method that remove_cwd_entries uses
(for some reason they differed). Don't assert that saved_errno
must be EPERM; it might be just about anything.

size for xnmalloc.
|
|
Don't add `1' to the buffer size (it was to protect against malloc
implementations that fail to allocate a buffer of size zero).
That is no longer necessary, since we use a malloc wrapper
on such systems.

mounted on the same mount point, prefer the last one, not the first.
Problem reported by Christian Jones in
<http://mail.gnu.org/archive/html/bug-coreutils/2004-04/msg00200.html>.
(show_disk): Remove unused statp arg. Return bool, not int.
(show_point): Rewrite to avoid gotos. Use the same algorithm
for lofs and dummies for each pass through the mount table,
rather than subtly different algorithms (which are probably
inadvertent).

use the chown(2) function, if possible.
(change_file_owner): Don't hard-code the
open/fchown/close kludge here. Use `chown' instead.
The chown function works just fine on conforming systems.
Other systems now go through the new chown wrapper that
resorts to the old kludge.

leading blanks when computing the location of the field end;
it is not supposed to skip trailing blanks. Solaris 8 "sort"
does conform to POSIX. Also fix the documentation to clarify
this and related issues.
(limfield): Use skipeblanks, not skipsblanks, to
decode whether to skip leading blanks.
(trailing_blanks): Remove.
(fillbuf, getmonth, keycompare): Don't trim trailing blanks.

happen between arbitrary output bytes, as the
restore-default-color sequence can bollix up multibyte chars or
color-change sequences in the ordinary output. Instead, process
signals only between printing a file name and changing the color
back to non_filename_text color. That way, if the signal handler
changes the color (to the default), 'ls' will change it back when
'ls' continues (after being suspended).
Also, do not bother with signal-handling unless stdout is a
controlling terminal; this lets stdio buffer better when "ls
--color" is piped or sent to a file.
(sigprocmask, sigset_t) [!defined SA_NOCLDSTOP]: New macros.
Do not include "full-write.h"; no longer needed.
(tcgetpgrp) [! HAVE_TCGETPGRP]: New macro.
(put_indicator_direct): Remove. All callers changed to use
put_indicator.
(caught_signals, interrupt_signal, stop_signal_count): New vars.
(restore_default_color): Don't bother checking for put_indicator
failure.
(sighandler): Don't handle SIGTSTP; that's another handler now.
Simply set interrupt_signal to the signal, then exit.
(stophandler, process_signals): New functions.
(main): Don't output any color changes until _after_ the signal
handlers are set up. This fixes a race condition where 'ls'
could be interrupted while initializing colors, and leaving the
terminal in an undesirable state.
Don't mess with signal-handling if standard output is not a
controlling terminal.
When exiting, restore the default color, then restore the
default signal handling, then act on any signals that weren't
acted on yet.
Do not print //DIRED// etc. in colors; this avoids the need
to catch signals when printing them.
(print_name_with_quoting): Process signals just before switching
color back to non_filename_text.

(quote_name): Use SIZE_MAX, not -1, in calls of quotearg_buffer.

- csplit didn't clean up if two signals arrived nearly simultaneously.
(sigprocmask, sigset_t) [!defined SA_NOCLDSTOP]: Define.
(filename_space, prefix, suffix, digits, files_created, remove_files): Now volatile.
(caught_signals): New var.
(cleanup): Block signals while deleting all files.
(cleanup_fatal, handle_line_error, regexp_error):
Mark with ATTRIBUTE_NORETURN.
(create_output_file, close_output_file, interrupt_handler):
Block signals while changing the number of output files,
to fix some race conditions.
(delete_all_files): Do nothing if remove_files is zero.
Clear files_created.
(main): Don't mess with signals until after argument processing is done.
(main): Rewrite signal-catching code to make it
similar to other coreutils programs. When processing signals,
block all signals that we catch, but do not block signals that we
don't catch. Avoid problems with unsigned int warnings.
(interrupt_handler): Use void, not (obsolete) RETSIGTYPE.
(interrupt_handler) [defined SA_NOCLDSTOP]:
Use simpler "signal (sig, SIG_DFL)" rather than sigaction equivalent.

(sighandler) [defined SA_NOCLDSTOP]:

(sighandler) [!defined SA_NOCLDSTOP]: Reset signal
handler to self, not to SIG_IGN, since SIGTSTP can be received more than once.
(main): Use SA_RESTART, as that is simpler than checking for EINTR
failures all over the place.

Include <signal.h>.
(main) [defined SIGCHLD]: Set SIGCHLD handler to the default,
if -s is given, since System V fork+wait does not work if SIGCHLD
is ignored.
