+ − 2915
+ − 2916 Expected exits occur when the user directs XEmacs to exit, for example
+ − 2917 by pressing the close button on the only frame in XEmacs, or by typing
+ − 2918 C-x C-c. This runs `save-buffers-kill-emacs', which saves any necessary
+ − 2919 buffers, and then exits using the primitive `kill-emacs'.
+ − 2920
+ − 2921 However, unexpected exits occur in a few different ways:
+ − 2922
+ − 2923 -- a memory access violation or other hardware-generated exception
+ − 2924 occurs. This is the worst possible problem to deal with, because
+ − 2925 the fault can occur while XEmacs is in any state whatsoever, even
+ − 2926 quite unstable ones. As a result, we need to be *extremely* careful
+ − 2927 what we do.
+ − 2928 -- we are using one X display (or if we've used more, we've closed the
+ − 2929 others already), and some hardware or other problem happens and
+ − 2930 suddenly we've lost our connection to the display. In this situation,
+ − 2931 things are not so dire as in the last one; our code itself isn't
+ − 2932 trashed, so we can continue execution as normal, after having set
+ − 2933 things up so that we can exit at the appropriate time. Our exit
+ − 2934 still needs to be of the emergency nature; we have no displays, so
+ − 2935 any attempts to use them will fail. We simply want to auto-save
+ − 2936 (the single most important thing to do during shut-down), do minimal
+ − 2937 cleanup of stuff that has an independent existence outside of XEmacs,
+ − 2938 and exit.
+ − 2939
+ − 2940 Currently, both unexpected exit scenarios described above set
+ − 2941 preparing_for_armageddon to indicate that nonessential and possibly
+ − 2942 dangerous things should not be done, specifically:
+ − 2943
+ − 2944 -- no garbage collection.
+ − 2945 -- no hooks are run.
+ − 2946 -- no messages of any sort from autosaving.
+ − 2947 -- autosaving tries harder, ignoring certain failures.
+ − 2948 -- existing frames are not deleted.
+ − 2949
+ − 2950 (Also, all places that set preparing_for_armageddon also
+ − 2951 set dont_check_for_quit. This happens separately because it's
+ − 2952 also necessary to set other variables to make absolutely sure
+ − 2953 no quitting happens.)
+ − 2954
+ − 2955 In the first scenario above (the access violation), we also set
+ − 2956 fatal_error_in_progress. This causes more things to not happen:
+ − 2957
