emacs: hanging in redisplay code?

emacs: hanging in redisplay code?

[T. V. Raman]

After last night's update from git, emacs  has become *really*
slow in things like filename completion. Turning on toggle debug
on quit shows the following backtrace:
Debugger entered--Lisp error: (quit)
  redisplay_internal\ \(C\ function\)()

I don't see any slowdown, FWIW.  How many files do you have in a
directory where you see slower completion?

about 100+  triggered it for me on my home machine --- 32bit
Ubuntu Jaunty --

Well, I see no slow-down in the Emacs src directory which holds more
than 230 files.

I may have mispoken the cause --- I was definitely seeing a slow
down -- and I hit c-g when it didn't respond.  Note: I cant see
the screen, so I am going by the debug trace to believe it was
screen refresh.  I'll rebuild tonight and see if I still see the problem.

emacs: hanging in redisplay code?

[T.V. Raman]

Did another update, make distclean and rebuilt, appears to be
running fine. Was either a transient problem which is gone, or it
needed  a make distclean; haven't done that in a while.

Still seeing sporadic hangs, e.g. when launching the VM  mail reader.

Following up:the culprit appears to have been
ido-max-directory-size being set to unlimited -- though why that
slowed vm down is still a mystery.

Hi Raman,

what version of VM are you running?

On the weekend, I had a similoar experience while running emacsclient
in a terminal and using VM. It only occured once and I've used VM
several times since with no issues. I don't use dio.

Am running vm from the bzr/git branch. I think this problem is
deper than vm -- it's proving fairly hard to debug.  I attributed
it first to filename completion; then to ido; then to vm -- and
 quitting the hang with toggle debug on quit set to t shows
 different answers.
