This runs `save-buffers-kill-emacs', which saves any necessary + buffers, and then exits using the primitive `kill-emacs'. + + However, unexpected exits occur in a few different ways: + + -- a memory access violation or other hardware-generated exception + occurs. This is the worst possible problem to deal with, because + the fault can occur while XEmacs is in any state whatsoever, even + quite unstable ones. As a result, we need to be *extremely* careful + what we do. + -- we are using one X display (or if we've used more, we've closed the + others already), and some hardware or other problem happens and + suddenly we've lost our connection to the display. In this situation, + things are not so dire as in the last one; our code itself isn't + trashed, so we can continue execution as normal, after having set + things up so that we can exit at the appropriate time. Our exit + still needs to be of the emergency nature; we have no displays, so + any attempts to use them will fail. We simply want to auto-save + (the single most important thing to do during shut-down), do minimal + cleanup of stuff that has an independent existence outside of XEmacs, + and exit. + + Currently, both unexpected exit scenarios described above set + preparing_for_armageddon to indicate that nonessential and possibly + dangerous things should not be done, specifically: + + -- no garbage collection. + -- no hooks are run. + -- no messages of any sort from autosaving. + -- autosaving tries harder, ignoring certain failures. + -- existing frames are not deleted. + + (Also, all places that set preparing_for_armageddon also + set dont_check_for_quit.

Iirc, tearoff toolbars is an option you can set in the gnome control panel. (the toolbox icon on the default panel, or under Settings on the main panel menu.

[crash] Popup menus, lwlib. 24 years, 7 months

Karl M. Hegbloom

Currently, with latest beta and HEAD, if I use the far button to bring up a popup mode menu, then click outside of the menu, XEmacs crashes with an assert failure. I don't understand `lwlib' much at all... I started poking around to see if I could fix it... At one point a function is called with an XPointer arg of -1, and that is cast to a Lisp_Object, then when the XCAR of that is taken, the assertion failure is thrown. I can try and spend time on learning how that works... but it would be faster if someone who already understands would do it. I have a HUGE reading list right now and would prefer to spend my time at that. -- I am karlheg of deB-ORG. You will be freed. mailto:karlheg＠debian.org (Karl M.

Are you using `glade' to build the interface, Bill? `apt-get install glade' -- I am karlheg of deB-ORG. You will be freed. mailto:karlheg＠debian.org (Karl M. Hegbloom) Portland, OR USA Debian GNU Potato Linux 2.2 AMD K6-200(＠233) XEmacs-21.2beta

So, is this at a point where we should send you lisp and/or C backtraces when things upshit and die? -- Michael D.
