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

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

113 version 16.60: released on September 19, 1985. These later version 16's
114 incorporated patches from the net, esp. for getting Emacs to work under
116 version 17.36 (first official v17 release) released on December 20, 1985.
117 Included a TeX-able user manual. First official unpatched version that

349 Some LISP-visible command-line options are set by XEmacs _before_ the

352 values XEmacs is getting at runtime. Such variables must be saved
353 before loading the dumpfile, and restored afterward.
355 Therefore these variables may not be initialized in vars_of_emacs().
357 The save/restore is done immediately before and after pdump_load() in
358 main_1(). See that function for the current list of protected variables.

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

593 The line above is original. Unfortunately, when an error is tripped
594 inside of the handler (e.g. during Fbacktrace()), and the handler for
595 the handler is invoked, it correctly notices that something is amiss
596 and it should just return -- but it returns EXCEPTION_CONTINUE_SEARCH,
597 which causes the debugger to be invoked debugging the handler code in
598 this function -- and WITH THE STACK UNWOUND so that you see main()
599 calling mswindows_handle_hardware_exceptions(), calling Fbacktrace(),
600 and a crash a couple of frames in -- AND NO SIGN OF THE ORIGINAL CRASH!
602 There's some real weirdness going on in the stack handling -- unlike
603 in Unix, where further crashes just keep adding to the stack, it seems
604 that under the structured-exception-handling, the stack can actually
605 bounce back and forth between the full stack at the location of the
606 exception and the unwound stack at the place where the __try clause was
607 established. I don't completely understand it. What I do know is that
608 returning EXCEPTION_EXECUTE_HANDLER on nested crash has the effect of
609 aborting execution of the handler and going back to the outer filter
610 function, which returns EXCEPTION_CONTINUE_SEARCH and everything is
611 hunky-dorey -- your debugger sees a crash at the right location with
614 I'm leaving in the trickier Unix-like code in the handler; someone who
615 understands better than me how the stack works in these handlers could
616 fix it up more. As it is, it works pretty well, so I'm not likely to
