2640 for doc-directory data-directory, etc.).

2642 temacs w/ run-temacs on the command line -- This is run to bytecompile
|

2643 all the out of date dumped lisp. It will execute both of the main_1
|
|
|
2644 calls and the second one must not touch the first computation because
|
|
|
2645 argc/argv are hosed the second time through.
|
|
|
2646
|

|
2647 xemacs -- Only the second main_1 is executed. The invocation path must
|

2873 /* Ben's capsule summary about expected and unexpected exits from XEmacs.
|
|
|
2874
|
|
|
2875 Expected exits occur when the user directs XEmacs to exit, for example
|
|
|
2876 by pressing the close button on the only frame in XEmacs, or by typing
|
|
|
2877 C-x C-c. This runs `save-buffers-kill-emacs', which saves any necessary
|
|
|
2878 buffers, and then exits using the primitive `kill-emacs'.
|
|
|
2879
|
|
|
2880 However, unexpected exits occur in a few different ways:
|
|
|
2881
|
|
|
2882 -- a memory access violation or other hardware-generated exception
|
|
|
2883 occurs. This is the worst possible problem to deal with, because
|
|
|
2884 the fault can occur while XEmacs is in any state whatsoever, even
|
|
|
2885 quite unstable ones. As a result, we need to be *extremely* careful
|
|
|
2886 what we do.
|
|
|
2887 -- we are using one X display (or if we've used more, we've closed the
|
|
|
2888 others already), and some hardware or other problem happens and
|
|
|
2889 suddenly we've lost our connection to the display. In this situation,
|
|
|
2890 things are not so dire as in the last one; our code itself isn't
|
|
|
2891 trashed, so we can continue execution as normal, after having set
|
|
|
2892 things up so that we can exit at the appropriate time. Our exit
|
|
|
2893 still needs to be of the emergency nature; we have no displays, so
|
|
|
2894 any attempts to use them will fail. We simply want to auto-save
|
|
|
2895 (the single most important thing to do during shut-down), do minimal
|
|
|
2896 cleanup of stuff that has an independent existence outside of XEmacs,
|
|
|
2897 and exit.
|
|
|
2898
|
|
|
2899 Currently, both unexpected exit scenarios described above set
|
|
|
2900 preparing_for_armageddon to indicate that nonessential and possibly
|
|
|
2901 dangerous things should not be done, specifically:
|
|
|
2902
|
|
|
2903 -- no garbage collection.
|
|
|
2904 -- no hooks are run.
|
|
|
2905 -- no messages of any sort from autosaving.
|
|
|
2906 -- autosaving tries harder, ignoring certain failures.
|
|
|
2907 -- existing frames are not deleted.
|
|
|
2908
|
|
|
2909 (Also, all places that set preparing_for_armageddon also
|
|
|
2910 set dont_check_for_quit. This happens separately because it's
|
|
|
2911 also necessary to set other variables to make absolutely sure
|
|
|
2912 no quitting happens.)
|
|
|
2913
|
|
|
2914 In the first scenario above (the access violation), we also set
|
|
|
2915 fatal_error_in_progress. This causes more things to not happen:
|
|
|
2916
|
|
|
2917 -- assertion failures do not abort.
|
|
|
2918 -- printing code does not do code conversion or gettext when
|
|
|
2919 printing to stdout/stderr.

3397 The line above is original. Unfortunately, when an error is tripped
|
|
|
3398 inside of the handler (e.g. during Fbacktrace()), and the handler for
|
|
|
3399 the handler is invoked, it correctly notices that something is amiss
|
|
|
3400 and it should just return -- but it returns EXCEPTION_CONTINUE_SEARCH,
|
|
|
3401 which causes the debugger to be invoked debugging the handler code in
|
|
|
3402 this function -- and WITH THE STACK UNWOUND so that you see main()
|
|
|
3403 calling mswindows_handle_hardware_exceptions(), calling Fbacktrace(),
|
|
|
3404 and a crash a couple of frames in -- AND NO SIGN OF THE ORIGINAL CRASH!
|
|
|
3405
|
|
|
3406 There's some real weirdness going on in the stack handling -- unlike
|
|
|
3407 in Unix, where further crashes just keep adding to the stack, it seems
|
|
|
3408 that under the structured-exception-handling, the stack can actually
|
|
|
3409 bounce back and forth between the full stack at the location of the
|
|
|
3410 exception and the unwound stack at the place where the __try clause was
|
|
|
3411 established. I don't completely understand it. What I do know is that
|
|
|
3412 returning EXCEPTION_EXECUTE_HANDLER on nested crash has the effect of
|
|
|
3413 aborting execution of the handler and going back to the outer filter
|
|
|
3414 function, which returns EXCEPTION_CONTINUE_SEARCH and everything is
|
|
|
3415 hunky-dorey -- your debugger sees a crash at the right location with
|
|
|
3416 the right stack.
|
|
|
3417
|
|
|
3418 I'm leaving in the trickier Unix-like code in the handler; someone who
|
|
|
3419 understands better than me how the stack works in these handlers could
|
|
|
3420 fix it up more. As it is, it works pretty well, so I'm not likely to

|

3421 touch it more. --ben
