- 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]:
Use simpler "signal (sig, SIG_DFL)" rather than sigaction equivalent.
(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.

Initialize a buffer to avoid warnings from tools like valgrind.

(path_free, path_init, path_prepend): New functions.
(nth_parent, find_dir_entry, robust_getcwd): New functions.
(main): First try getcwd, then, upon failure, robust_getcwd.

Remove anachronistic casts.

and new dd options iflag= and oflag=.
(usage): Document.
(fdatasync) [!HAVE_FDATASYNC]: New macro.
(C_NOCREAT, C_EXCL, C_FDATASYNC, C_FSYNC): New macros.
(input_flags, output_flags): New vars.
(LONGEST_SYMBOL): New macro.
(struct symbol_value): Renamed from struct conversion. Members
symbol and value renamed from convname and conversion. The
symbol value is now an array instead of a pointer; this saves
a bit of space and time in practice. All uses changed.
(conversions): Add nocreat, excl, fdatasync, fsync. Now const.
(flags): New constant array.
(iflag_error_msgid, oflag_error_msgid): New constants.
(parse_symbols): Renamed from parse_conversion and generalized
to handle either conversion or flag symbols.
(scanargs): Adjust uses of parse_symbols accodingly. Add
support for iflag= and oflag=. Reject attempts to use
both excl and nocreat.
(set_fd_flags): New function.
(dd_copy): Just return X rather than calling quit (X), since our
caller invokes quit with the returned value. Add support for
fdatasync and fsync.
(main): Add support for iflags=, oflags=, and new conv= symbols.
