Hello,
I have a problem with the current CVS emacs.
When I work with tramp, for instance /su:root@localhost:/etc/hosts
tramp asks me about "undo" information on each save, for the buffer
*tram su root localhost* buffer.
emacs asks me if I want to discard a number of bytes of undo
information. This is very inconvenient.
Regards,

It is not normal, as for me it works without problems. With this weeks CVS
version.

Please send a precise self-contained test case so we can figure
out the cause of the problem.

This can happen if you edit *large* files, and the contents of these
files appears temporarily in that internal buffer. Mostly, people
don't see it because the files are not so huge. Your "/etc/hosts"
shouldn't be so large either; I don't know why it happens to *you*.
Very inconvenient, indeed. I've added a patch to Tramp that the buffer
local variable `buffer-undo-list' of that buffer is set to t, which is
sufficient because there's nothing to be inspected later on.
Will be available in Emacs CVS with next Tramp sync.

Best regards, Michael.

Below I've tried to provide a more precise testcase.
with cvs emacs of 20041226 do:
emacs --no-init -nw /su:root@localhost:/tmp/tsta
type your root pwd
type 1234567890 and save the buffer
jump to a new buffer tstb type 1234567890 and save it
repeat this process about 4 times
you will get this question:
Buffer *tramp/su root@localhost* undo info is 417914 bytes long; discard it? (yes or no)
its not entirely consistent, but I tried several times and was able to
repeatedly evoke the problem. The size of the testbuffers doesnt seem
to matter much, I tried much larger buffers, and what matters is the
number of times you switch buffers and save them.
You probably dont need to be root of course either.
