102 GNU Emacs version 15 (15.34) was released on May 7, 1985 and

374 before loading the dumpfile, and restored afterward.

431 /* Ben's capsule summary about expected and unexpected exits from SXEmacs.
433 Expected exits occur when the user directs SXEmacs to exit, for example
434 by pressing the close button on the only frame in SXEmacs, or by typing
435 C-x C-c. This runs `save-buffers-kill-emacs', which saves any necessary
436 buffers, and then exits using the primitive `kill-emacs'.
438 However, unexpected exits occur in a few different ways:
440 -- a memory access violation or other hardware-generated exception
441 occurs. This is the worst possible problem to deal with, because
442 the fault can occur while SXEmacs is in any state whatsoever, even
443 quite unstable ones. As a result, we need to be *extremely* careful
445 -- we are using one X display (or if we've used more, we've closed the
446 others already), and some hardware or other problem happens and
447 suddenly we've lost our connection to the display. In this situation,
448 things are not so dire as in the last one; our code itself isn't
449 trashed, so we can continue execution as normal, after having set
450 things up so that we can exit at the appropriate time. Our exit
451 still needs to be of the emergency nature; we have no displays, so
452 any attempts to use them will fail. We simply want to auto-save
453 (the single most important thing to do during shut-down), do minimal
454 cleanup of stuff that has an independent existence outside of SXEmacs,
457 Currently, both unexpected exit scenarios described above set
458 preparing_for_armageddon to indicate that nonessential and possibly
459 dangerous things should not be done, specifically:
461 -- no garbage collection.
463 -- no messages of any sort from autosaving.
464 -- autosaving tries harder, ignoring certain failures.
465 -- existing frames are not deleted.
467 (Also, all places that set preparing_for_armageddon also
468 set dont_check_for_quit. This happens separately because it's
469 also necessary to set other variables to make absolutely sure
470 no quitting happens.)
472 In the first scenario above (the access violation), we also set
473 fatal_error_in_progress. This causes more things to not happen:
475 -- assertion failures do not abort.
476 -- printing code does not do code conversion or gettext when
477 printing to stdout/stderr.
