Expected exits occur when the user directs XEmacs to exit, for example by pressing the close button on the only frame in XEmacs, or by typing C-x C-c. This runs `save-buffers-kill-emacs', which saves any necessary buffers, and then exits using the primitive `kill-emacs'. However, unexpected exits occur in a few different ways: -- a memory access violation or other hardware-generated exception occurs. This is the worst possible problem to deal with, because the fault can occur while XEmacs is in any state whatsoever, even quite unstable ones. As a result, we need to be *extremely* careful what we do. -- we are using one X display (or if we've used more, we've closed the others already), and some hardware or other problem happens and suddenly we've lost our connection to the display. In this situation, things are not so dire as in the last one; our code itself isn't trashed, so we can continue execution as normal, after having set things up so that we can exit at the appropriate time. Our exit still needs to be of the emergency nature; we have no displays, so any attempts to use them will fail. We simply want to auto-save (the single most important thing to do during shut-down), do minimal cleanup of stuff that has an independent existence outside of XEmacs, and exit. Currently, both unexpected exit scenarios described above set preparing_for_armageddon to indicate that nonessential and possibly dangerous things should not be done, specifically: -- no garbage collection. -- no hooks are run. -- no messages of any sort from autosaving. -- autosaving tries harder, ignoring certain failures. -- existing frames are not deleted. (Also, all places that set preparing_for_armageddon also set dont_check_for_quit. This happens separately because it's also necessary to set other variables to make absolutely sure no quitting happens.) In the first scenario above (the access violation), we also set fatal_error_in_progress. This causes more things to not happen: -- assertion failures do not abort. -- printing code does not do code conversion or gettext when printing to stdout/stderr. */ /* Nonzero if handling a fatal error already. */ int fatal_error_in_progress; /* Non-nil means we're going down, so we better not run any hooks or do other non-essential stuff. */ int preparing_for_armageddon; /* Nonzero means we're in an unstable situation and need to skip i18n conversions and such during printing. */ int inhibit_non_essential_printing_operations; static JMP_BUF run_temacs_catch; static int run_temacs_argc; static char **run_temacs_argv; static char *run_temacs_args; static EMACS_INT run_temacs_argv_size; static EMACS_INT run_temacs_args_size; static void shut_down_emacs (int sig, Lisp_Object stuff, int no_auto_save); /* ------------------------------- */ /* low-level debugging functions */ /* ------------------------------- */ #if defined (WIN32_NATIVE) && defined (DEBUG_XEMACS) #define debugging_breakpoint() DebugBreak () #else #define debugging_breakpoint() #endif void debug_break (void) { debugging_breakpoint (); } #if defined (WIN32_NATIVE) || defined (CYGWIN) /* Return whether all bytes in the specified memory block can be read. */ int debug_can_access_memory (void *ptr, Bytecount len) { return !IsBadReadPtr (ptr, len); } #else /* !(defined (WIN32_NATIVE) || defined (CYGWIN)) */ /* #### There must be a better way!!!! */ static JMP_BUF memory_error_jump; static SIGTYPE debug_memory_error (int signum) { EMACS_REESTABLISH_SIGNAL (signum, debug_memory_error); EMACS_UNBLOCK_SIGNAL (signum); LONGJMP (memory_error_jump, 1); } /* Return whether all bytes in the specified memory block can be read. */ int debug_can_access_memory (void *ptr, Bytecount len) { /* Use volatile to protect variables from being clobbered by longjmp. */ SIGTYPE (*volatile old_sigbus) (int); SIGTYPE (*volatile old_sigsegv) (int); volatile int old_errno = errno; volatile int retval = 1; if (!SETJMP (memory_error_jump)) { old_sigbus = (SIGTYPE (*) (int)) signal (SIGBUS, debug_memory_error); old_sigsegv = (SIGTYPE (*) (int)) signal (SIGSEGV, debug_memory_error); if (len > 1) /* If we can, try to avoid problems with super-optimizing compilers that might decide that memcmp (ptr, ptr, len) can be optimized away since its result is always 1. */ memcmp (ptr, (char *) ptr + 1, len - 1); else memcmp (ptr, ptr, len); } else retval = 0; signal (SIGBUS, old_sigbus); signal (SIGSEGV, old_sigsegv); errno = old_errno; return retval; } #endif /* defined (WIN32_NATIVE) || defined (CYGWIN) */ #ifdef DEBUG_XEMACS DEFUN ("force-debugging-signal", Fforce_debugging_signal, 0, 1, 0, /* Cause XEmacs to enter the debugger.
