104 GNU Emacs version 15 (15.34) was released sometime in 1984 or 1985 and
105 shared some code with a version of Emacs written by James Gosling (the
106 same James Gosling who later created the Java language).

108 July 15, 1985. All Gosling code was removed due to potential copyright
109 problems with the code.

112 version 16.60: released on September 19, 1985. These later version 16's
113 incorporated patches from the net, esp. for getting Emacs to work under
115 version 17.36 (first official v17 release) released on December 20, 1985.

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

587 The line above is original. Unfortunately, when an error is tripped
588 inside of the handler (e.g. during Fbacktrace()), and the handler for
589 the handler is invoked, it correctly notices that something is amiss
590 and it should just return -- but it returns EXCEPTION_CONTINUE_SEARCH,
591 which causes the debugger to be invoked debugging the handler code in
592 this function -- and WITH THE STACK UNWOUND so that you see main()
593 calling mswindows_handle_hardware_exceptions(), calling Fbacktrace(),
594 and a crash a couple of frames in -- AND NO SIGN OF THE ORIGINAL CRASH!
596 There's some real weirdness going on in the stack handling -- unlike
597 in Unix, where further crashes just keep adding to the stack, it seems
598 that under the structured-exception-handling, the stack can actually
599 bounce back and forth between the full stack at the location of the
600 exception and the unwound stack at the place where the __try clause was
601 established. I don't completely understand it. What I do know is that
602 returning EXCEPTION_EXECUTE_HANDLER on nested crash has the effect of
