383 /* Ben's capsule summary about expected and unexpected exits from XEmacs.
|
|
|
384
|
|
|
385 Expected exits occur when the user directs XEmacs to exit, for example
|
|
|
386 by pressing the close button on the only frame in XEmacs, or by typing
|
|
|
387 C-x C-c. This runs `save-buffers-kill-emacs', which saves any necessary
|
|
|
388 buffers, and then exits using the primitive `kill-emacs'.
|
|
|
389
|
|
|
390 However, unexpected exits occur in a few different ways:
|
|
|
391
|
|
|
392 -- a memory access violation or other hardware-generated exception
|
|
|
393 occurs. This is the worst possible problem to deal with, because
|
|
|
394 the fault can occur while XEmacs is in any state whatsoever, even
|
|
|
395 quite unstable ones. As a result, we need to be *extremely* careful
|
|
|
396 what we do.
|
|
|
397 -- we are using one X display (or if we've used more, we've closed the
|
|
|
398 others already), and some hardware or other problem happens and
|
|
|
399 suddenly we've lost our connection to the display. In this situation,
|
|
|
400 things are not so dire as in the last one; our code itself isn't
|
|
|
401 trashed, so we can continue execution as normal, after having set
|
|
|
402 things up so that we can exit at the appropriate time. Our exit
|
|
|
403 still needs to be of the emergency nature; we have no displays, so
|
|
|
404 any attempts to use them will fail. We simply want to auto-save
|
|
|
405 (the single most important thing to do during shut-down), do minimal
|
|
|
406 cleanup of stuff that has an independent existence outside of XEmacs,
|
|
|
407 and exit.
|
|
|
408
|
|
|
409 Currently, both unexpected exit scenarios described above set
|
|
|
410 preparing_for_armageddon to indicate that nonessential and possibly
|
|
|
411 dangerous things should not be done, specifically:
|
|
|
412
|
|
|
413 -- no garbage collection.
|
|
|
414 -- no hooks are run.
|
|
|
415 -- no messages of any sort from autosaving.
|
|
|
416 -- autosaving tries harder, ignoring certain failures.
|
|
|
417 -- existing frames are not deleted.
|
|
|
418
|
|
|
419 (Also, all places that set preparing_for_armageddon also
|
|
|
420 set dont_check_for_quit. This happens separately because it's
|
|
|
421 also necessary to set other variables to make absolutely sure
|
|
|
422 no quitting happens.)
|
|
|
423
|
|
|
424 In the first scenario above (the access violation), we also set
|
|
|
425 fatal_error_in_progress. This causes more things to not happen:
|
|
|
426
|
|
|
427 -- assertion failures do not abort.
|
|
|
428 -- printing code does not do code conversion or gettext when
|
|
|
429 printing to stdout/stderr.

566 The line above is original. Unfortunately, when an error is tripped

567 inside of the handler (e.g. during Fbacktrace()), and the handler for
|
|
|
568 the handler is invoked, it correctly notices that something is amiss
|
|
|
569 and it should just return -- but it returns EXCEPTION_CONTINUE_SEARCH,
|
|
|
570 which causes the debugger to be invoked debugging the handler code in
|
|
|
571 this function -- and WITH THE STACK UNWOUND so that you see main()
|
|
|
572 calling mswindows_handle_hardware_exceptions(), calling Fbacktrace(),
|
|
|
573 and a crash a couple of frames in -- AND NO SIGN OF THE ORIGINAL CRASH!
|
|
|
574
|
|
|
575 There's some real weirdness going on in the stack handling -- unlike
|
|
|
576 in Unix, where further crashes just keep adding to the stack, it seems
|
|
|
577 that under the structured-exception-handling, the stack can actually
|
|
|
578 bounce back and forth between the full stack at the location of the
|
|
|
579 exception and the unwound stack at the place where the __try clause was
|
|
|
580 established. I don't completely understand it. What I do know is that
|
|
|
581 returning EXCEPTION_EXECUTE_HANDLER on nested crash has the effect of
|
|
|
582 aborting execution of the handler and going back to the outer filter
|
|
|
583 function, which returns EXCEPTION_CONTINUE_SEARCH and everything is
|
|
|
584 hunky-dorey -- your debugger sees a crash at the right location with
|
|
|
585 the right stack.
|
|
|
586
|
|
|
587 I'm leaving in the trickier Unix-like code in the handler; someone who
|
|
|
588 understands better than me how the stack works in these handlers could
|
|
|
589 fix it up more. As it is, it works pretty well, so I'm not likely to

2483 all the out of date dumped lisp. It will execute both of the main_1
|
|
|
2484 calls and the second one must not touch the first computation because
|
|
|
2485 argc/argv are hosed the second time through.
|
|
|
2486
|
|
|
2487 xemacs -- Only the second main_1 is executed. The invocation path must
|
|
|
2488 computed but this only matters when running in place or when running

2489 as a login shell.
