2650 for doc-directory data-directory, etc.).

2652 temacs w/ run-temacs on the command line -- This is run to bytecompile
|

2653 all the out of date dumped lisp. It will execute both of the main_1
|
|
|
2654 calls and the second one must not touch the first computation because
|
|
|
2655 argc/argv are hosed the second time through.
|
|
|
2656
|

|
2657 xemacs -- Only the second main_1 is executed. The invocation path must
|
|

2658 computed but this only matters when running in place or when running

2885 /* Ben's capsule summary about expected and unexpected exits from XEmacs.
|
|
|
2886
|
|
|
2887 Expected exits occur when the user directs XEmacs to exit, for example
|
|
|
2888 by pressing the close button on the only frame in XEmacs, or by typing
|
|
|
2889 C-x C-c. This runs `save-buffers-kill-emacs', which saves any necessary
|
|
|
2890 buffers, and then exits using the primitive `kill-emacs'.
|
|
|
2891
|
|
|
2892 However, unexpected exits occur in a few different ways:
|
|
|
2893
|
|
|
2894 -- a memory access violation or other hardware-generated exception
|
|
|
2895 occurs. This is the worst possible problem to deal with, because
|
|
|
2896 the fault can occur while XEmacs is in any state whatsoever, even
|
|
|
2897 quite unstable ones. As a result, we need to be *extremely* careful
|
|
|
2898 what we do.
|
|
|
2899 -- we are using one X display (or if we've used more, we've closed the
|
|
|
2900 others already), and some hardware or other problem happens and
|
|
|
2901 suddenly we've lost our connection to the display. In this situation,
|
|
|
2902 things are not so dire as in the last one; our code itself isn't
|
|
|
2903 trashed, so we can continue execution as normal, after having set
|
|
|
2904 things up so that we can exit at the appropriate time. Our exit
|
|
|
2905 still needs to be of the emergency nature; we have no displays, so
|
|
|
2906 any attempts to use them will fail. We simply want to auto-save
|
|
|
2907 (the single most important thing to do during shut-down), do minimal
|
|
|
2908 cleanup of stuff that has an independent existence outside of XEmacs,
|
|
|
2909 and exit.
|
|
|
2910
|
|
|
2911 Currently, both unexpected exit scenarios described above set
|
|
|
2912 preparing_for_armageddon to indicate that nonessential and possibly
|
|
|
2913 dangerous things should not be done, specifically:
|
|
|
2914
|
|
|
2915 -- no garbage collection.
|
|
|
2916 -- no hooks are run.
|
|
|
2917 -- no messages of any sort from autosaving.
|
|
|
2918 -- autosaving tries harder, ignoring certain failures.
|
|
|
2919 -- existing frames are not deleted.
|
|
|
2920
|
|
|
2921 (Also, all places that set preparing_for_armageddon also
|
|
|
2922 set dont_check_for_quit. This happens separately because it's
|
|
|
2923 also necessary to set other variables to make absolutely sure
|
|
|
2924 no quitting happens.)
|

3431 The line above is original. Unfortunately, when an error is tripped
|
|
|
3432 inside of the handler (e.g. during Fbacktrace()), and the handler for
|
|
|
3433 the handler is invoked, it correctly notices that something is amiss
|
|
|
3434 and it should just return -- but it returns EXCEPTION_CONTINUE_SEARCH,
|
|
|
3435 which causes the debugger to be invoked debugging the handler code in
|
|
|
3436 this function -- and WITH THE STACK UNWOUND so that you see main()
|
|
|
3437 calling mswindows_handle_hardware_exceptions(), calling Fbacktrace(),
|
|
|
3438 and a crash a couple of frames in -- AND NO SIGN OF THE ORIGINAL CRASH!
|
|
|
3439
|
|
|
3440 There's some real weirdness going on in the stack handling -- unlike
|
|
|
3441 in Unix, where further crashes just keep adding to the stack, it seems
|
|
|
3442 that under the structured-exception-handling, the stack can actually
|
|
|
3443 bounce back and forth between the full stack at the location of the
|
|
|
3444 exception and the unwound stack at the place where the __try clause was
|
|
|
3445 established. I don't completely understand it. What I do know is that
|
|
|
3446 returning EXCEPTION_EXECUTE_HANDLER on nested crash has the effect of
|
|
|
3447 aborting execution of the handler and going back to the outer filter
|
|
|
3448 function, which returns EXCEPTION_CONTINUE_SEARCH and everything is
|
|
|
3449 hunky-dorey -- your debugger sees a crash at the right location with
|
|
|
3450 the right stack.
|
|
|
3451
|
|
|
3452 I'm leaving in the trickier Unix-like code in the handler; someone who
|
|
|
3453 understands better than me how the stack works in these handlers could
|
|
|
3454 fix it up more. As it is, it works pretty well, so I'm not likely to

3455 touch it more. --ben
