Re: GNU Emacs crashes with longlines-mode and outline-mode

Does this fail for you with the latest sources?

A reduced test case below. I am still looking for what outline mode does
that triggers the crash. Setting up the invisibility spec to show
ellipses, creating an overlay at the end of the buffer and making it
invisible was not sufficient. Perhaps someone more familiar with outline
mode and/or the parts of redisplay that deal with invisibility and
ellipses might have an idea where to look?

-*- mode: text; mode: outline -*-
(put-text-property (- (point-max) 1) (point-max) 'display "X")
Evaluate the above line (C-x C-e), then hide the leaf node below (C-c C-l):

* One chapter

Some text. Some text that must be longer than one line, to test

Re: 23.0.50; error when M-x menu-bar-open

Can you still reproduce this?  If so, could you please debug
`fit-window-to-buffer' to find out how it sets `delta' to -52?

What do the "ad-Orig-..." do?  What is the value of `window-min-height'
when they attempt to split the window?

Re: show-trailing-whitespace makes M-x zone look ugly

() "Chris Moore" <christopher.ian.moore <at> gmail.com>
() Mon, 1 Oct 2007 00:20:45 +0200

   If I enable show-trailing-whitespace and run M-x zone then the display
   looks bad.  In the mode where zone is dropping z's down the screen,
   there are horizontal stripes, because the buffer is full of trailing
   whitespace.

   A quick fix for this would probably be to locally bind
   show-trailing-whitespace to nil while zone is running.

thanks for the suggestion.  i have let-bound show-trailing-whitespace to
nil in `zone'.  perhaps this fix will be both quick and enduring.

Yes. I've revised the test case below to make it clearer. The problem
seems to occur when the character at point-max is hidden by outline-mode
and has a display text property on it. There seems to be something
peculiar to the way outline-mode hides text that I have missed, as I
haven't managed to eliminate outline-mode from this by setting the
invisible property directly.

-*- mode: text; mode: outline -*-
(put-text-property (- (point-max) 1) (point-max) 'display "X")
Evaluate the above line (C-x C-e), then hide the leaf node below (C-c C-l):

Some text. This line must not end with a newline

Re: 23.0.50; Cannot run calculator on TTY


Apologies about the Ad-orig -- that's because everything has been
advised by Emacspeak.

window-min-height is 4 -- I've not changed it.

I understand.  The problem is that apparently

   ad-Orig-calculator()

wants to do

   split-window-vertically(-2)

which eventually has `split-window' complain.  If you bind
`window-min-height' to 2 around this the complaints should go away,
hopefully.

 > window-min-height is 4 -- I've not changed it.

Did you change it earlier?

Sounds good.  Would someone please do it?
