2644 for doc-directory data-directory, etc.).

2646 temacs w/ run-temacs on the command line -- This is run to bytecompile
|

2647 all the out of date dumped lisp. It will execute both of the main_1
|
|
|
2648 calls and the second one must not touch the first computation because
|
|
|
2649 argc/argv are hosed the second time through.
|
|
|
2650
|

|
2651 xemacs -- Only the second main_1 is executed. The invocation path must
|
|
|
2652 computed but this only matters when running in place or when running

2877 /* Ben's capsule summary about expected and unexpected exits from XEmacs.
|
|
|
2878
|
|
|
2879 Expected exits occur when the user directs XEmacs to exit, for example
|
|
|
2880 by pressing the close button on the only frame in XEmacs, or by typing
|
|
|
2881 C-x C-c. This runs `save-buffers-kill-emacs', which saves any necessary
|
|
|
2882 buffers, and then exits using the primitive `kill-emacs'.
|
|
|
2883
|
|
|
2884 However, unexpected exits occur in a few different ways:
|
|
|
2885
|
|
|
2886 -- a memory access violation or other hardware-generated exception
|
|
|
2887 occurs. This is the worst possible problem to deal with, because
|
|
|
2888 the fault can occur while XEmacs is in any state whatsoever, even
|
|
|
2889 quite unstable ones. As a result, we need to be *extremely* careful
|
|
|
2890 what we do.
|
|
|
2891 -- we are using one X display (or if we've used more, we've closed the
|
|
|
2892 others already), and some hardware or other problem happens and
|
|
|
2893 suddenly we've lost our connection to the display. In this situation,
|
|
|
2894 things are not so dire as in the last one; our code itself isn't
|
|
|
2895 trashed, so we can continue execution as normal, after having set
|
|
|
2896 things up so that we can exit at the appropriate time. Our exit
|
|
|
2897 still needs to be of the emergency nature; we have no displays, so
|
|
|
2898 any attempts to use them will fail. We simply want to auto-save
|
|
|
2899 (the single most important thing to do during shut-down), do minimal
|
|
|
2900 cleanup of stuff that has an independent existence outside of XEmacs,
|
|
|
2901 and exit.
|
|
|
2902
|
|
|
2903 Currently, both unexpected exit scenarios described above set
|
|
|
2904 preparing_for_armageddon to indicate that nonessential and possibly
|
|
|
2905 dangerous things should not be done, specifically:
|
|
|
2906
|
|
|
2907 -- no garbage collection.
|
|
|
2908 -- no hooks are run.
|
|
|
2909 -- no messages of any sort from autosaving.
|
|
|
2910 -- autosaving tries harder, ignoring certain failures.
|
|
|
2911 -- existing frames are not deleted.
|
|
|
2912
|
|
|
2913 (Also, all places that set preparing_for_armageddon also
|
|
|
2914 set dont_check_for_quit. This happens separately because it's
|
|
|
2915 also necessary to set other variables to make absolutely sure
|
|
|
2916 no quitting happens.)
|
|
|
2917
|
|
|
2918 In the first scenario above (the access violation), we also set
|
|
|
2919 fatal_error_in_progress. This causes more things to not happen:
|
|
|
2920
|
|
|
2921 -- assertion failures do not abort.
|
|
|
2922 -- printing code does not do code conversion or gettext when
|
|
|
2923 printing to stdout/stderr.

3403 The line above is original. Unfortunately, when an error is tripped
|
|
|
3404 inside of the handler (e.g. during Fbacktrace()), and the handler for
|
|
|
3405 the handler is invoked, it correctly notices that something is amiss
|
|
|
3406 and it should just return -- but it returns EXCEPTION_CONTINUE_SEARCH,
|
|
|
3407 which causes the debugger to be invoked debugging the handler code in
|
|
|
3408 this function -- and WITH THE STACK UNWOUND so that you see main()
|
|
|
3409 calling mswindows_handle_hardware_exceptions(), calling Fbacktrace(),
|
|
|
3410 and a crash a couple of frames in -- AND NO SIGN OF THE ORIGINAL CRASH!
|
|
|
3411
|
|
|
3412 There's some real weirdness going on in the stack handling -- unlike
|
|
|
3413 in Unix, where further crashes just keep adding to the stack, it seems
|
|
|
3414 that under the structured-exception-handling, the stack can actually
|
|
|
3415 bounce back and forth between the full stack at the location of the
|
|
|
3416 exception and the unwound stack at the place where the __try clause was
|
|
|
3417 established. I don't completely understand it. What I do know is that
|
|
|
3418 returning EXCEPTION_EXECUTE_HANDLER on nested crash has the effect of
|
|
|
3419 aborting execution of the handler and going back to the outer filter
|
|
|
3420 function, which returns EXCEPTION_CONTINUE_SEARCH and everything is
|
|
|
3421 hunky-dorey -- your debugger sees a crash at the right location with
|
|
|
3422 the right stack.
|
|
|
3423
|
|
|
3424 I'm leaving in the trickier Unix-like code in the handler; someone who
|
|
|
3425 understands better than me how the stack works in these handlers could
|
|
|
3426 fix it up more. As it is, it works pretty well, so I'm not likely to

|

3427 touch it more. --ben
