bug#2223: 23.0.90; *compilation* hangs and fails to scroll

[Marshall, Simon]

I can confirm that emacs-23.0.91 no longer hangs, thanks, however it
does still fail to scroll.

You will need a Makefile that is going to output a long line.  This
works for me:

all:
        @echo the 2+K char very long line copied from my real makefile

Now emacs -Q and eval in *scratch*

(setq compilation-scroll-output t)
(setq special-display-frame-alist nil)
(setq compile-frame-alist
      (append '((width . 150) (height . 15))
              '((left . 25) (top . 75))
              '((menu-bar-lines . 1))
              special-display-frame-alist))
(setq special-display-buffer-names
      (list (cons "*compilation*" compile-frame-alist)))

Now do Tools > Compile... RET and I see Emacs create the *compilation*
window frame and insert chunks of the echo output before eventually not
scrolling the *compilation* window.  It doesn't stop scrolling at the
same time with each recompile.

Simon.

This may have been related to the recent atimer problems, which have now
been fixed.  Is this bug still present with latest CVS?
