| | | | | | | | | | | | | | (ENOTSUP): Define if errno.h doesn't. (SA_NODEFER, SA_ONSTACK, SA_RESETHAND, SA_SIGINFO, SIGSTKSZ, _SC_PAGESIZE, ALTERNATE_STACK_SIZE, stack_t, sigaltstack): Remove; we now assume them all when HAVE_XSI_STACK_OVERFLOW_HEURISTIC, so we don't need substitutes. (<ucontext.h>): Include only if HAVE_XSI_STACK_OVERFLOW_HEURISTIC. (alternate_signal_stack): Now of size SIGSTKSZ, not ALTERNATE_STACK_SIZE.

| | | | | | | | | | | 0 -> EXIT_SUCCESS, 1 -> EXIT_FAILURE, 2 -> EXIT_TROUBLE. (ck_editor_status): New function. (main): Check for stack overflow. Adopt POSIX convention for subsidiary programs not found. (diffarg): Check for integer overflow to avoid core dumps. (trapsigs): Remove SA_INTERRUPT special case; now done by header. (SIGCHLD): Likewise. (edit): Adopt POSIX convention for subsidiary programs not found.
* (sip): Avoid integer overflow and core dumps if buffer alignments arePaul Eggert2002-02-281-48/+92
| | | | | | | | | | | preposterously incompatible. (slurp): Do not dump core if the file is growing as we read it. If a regular file grows, keep reading until we catch up with its EOF. (find_and_hash_each_line): Check for integer overflow to avoid core dumps. (GUESS_LINES): Remove. (guess_lines): New function. Avoid integer overflow. (find_identical_ends): Use it. Avoid integer overflow and possible core dumps.
* (format_group, print_ifdef_lines): Avoid core dumps withPaul Eggert2002-02-281-17/+17
| | | | | bad formats. (do_printf_spec): Avoid alloca.

| | | | | Check for integer overflow to avoid core dumps. (diff_dirs): 0 -> EXIT_SUCCESS, 2 -> EXIT_TROUBLE.
* Include c-stack.h, exitfail.h.Paul Eggert2002-02-281-51/+63
| | | | | | | | | | | | | | | | | (ALLOCATE): Remove. All uses changed to xmalloc, or to xmalloc plus an overflow check. (myread): Remove. (main): Check for stack overflow. 0 -> EXIT_SUCCESS, 1 -> EXIT_FAIULRE, 2 -> EXIT_TROUBLE. (try_help): Likewise. (process_diff): Check for integer overflow, to avoid core dumps. 2 -> EXIT_TROUBLE. (read_diff): Exit with status 126 if the file is not executable, for compatibility with POSIX 1003.1-2001. Accommodate ancient AIX hosts that set errno to EINTR after uncaught SIGCONT. Check for integer overflow to avoid core dumps. (fatal, perror_with_exit): 2 -> EXIT_TROUBLE.
* Include c-stack.h, exitfail.h.Paul Eggert2002-02-281-225/+261
| | | | | | | | | | | | | | | | | | | | | | | | | | | Do not include signal.h. (specify_style, specify_value): Bring these routines back, as POSIX requires that the order of options not matter. (shortopts): New constant. (group_format_option, line_format_option): New constants. (LONG_OPTION, GROUP_FORMAT_OPTION, LINE_FORMAT_OPTION): New macros. (longopts): Use them. (main): 0 -> EXIT_SUCCESS, 1 -> EXIT_FAILURE, 2 -> EXIT_TROUBLE. Ensure that order of options does not matter. Check for stack overflow. If contexts overflow, substitute LIN_MAX, as that's good enough. If multiple contexts are specified, use their maximum. -c is equivalent to -C 3 now, instead of having an implicit context; likewise for -u and -U 3. Use specify_style and specify_value. (SIGCHLD): Do not define; now done in a header. Use new style time stamp format for -u / -U. Reject numeric-string options if operating in POSIX 1003.1-2001 mode. Avoid overflow problems with tab width. Simplify from-file and to-file code. (usage): Do not mention obsolete options. (filetype): Do not mention whether a file is executable. Add typed memory objects. (compare_files): 0 -> EXIT_SUCCESS, 1 -> EXIT_FAILURE, 2 -> EXIT_TROUBLE.
