Package: ncurses-developer
Version: 1.9.2c-1

To reproduce:
 * start dselect 0.93.53;
 * enter the package list (option 2);
 * hit ^L to redraw the display.

The result is a coredump in wnoutrefresh.  The arguments appear to be
sane.  I haven't investigated whether this is an overwriting (memory
corruption) problem in dselect because the last time I had an
overwriting problem it turned out to be ncurses infecting the rest of
the program rather than the other way around.

The bug happens with 0.93.42.3 too, and probably with other versions.

If you want to debug this and have Electric Fence installed the
easiest way is probably to use the `debugmake' script in the dpkg
0.93.53 source tarfile's `lib' and `dselect' directories.

dpkg-0.93.53.tar.gz is currently in private/project/ALPHA; when I
upload dpkg 0.93.54 I'll move it to dpkg-0.93.53-ncursesbug.tar.gz.

Ian.

Ian, is this still happening with ncurses-1.9.3 ?

No, it's not.  However it's still doing something very weird that I
think is probably a bug somewhere.

Here is a typescript which demonstrates the effect.  For best results
use something like
 slowprint 0.001 <typescript
to see what's going on.  (slowprint is the Perl script below.)

This was in an 80x24 xterm.

Can we please keep this bug open until the question of precisely how I
should refresh the display in dselect is resolved, as well as all the
related ncurses code and documentation bugs ?

On my ANSI terminal emulation at work, it looked OK, though some of the
decisions it made about movement optimization were strange. I'll look at it on
my Linux at home as soon as I can to see if it's a linux-terminfo problem. If
it's solely a matter of not liking the movement optimization, I think we
should wait before complaining about that, as they've just worked over the
movement optimization for the next release.

What were you running it under? Xterm? The linux console? What was $TERM
set to? Did it behave the same way under both xterm and the console?

If I'm seeing what you are complaining about, I'm perhaps not recognizing it.
Can I have a few more words about what "something very weird" is?

	Thanks

	Bruce

Sorry, I've not made myself clear.

You'll notice that it redraws a rectangle near the top left of the
package list before everything else.

I find this highly suspicious.  There is nothing in my code that makes
that rectangle special; the whole package list is a single pad which
is pnoutrefresh'd all at once.  The displayed data doesn't make it
special either.

I think that this bizarre redraw order is another symptom of the same
bug that caused the coredump with 1.9.2c.  It seems likely to me that
it is coincidence that with 1.9.3 the numbers that are the corners of
the rectangle are sane enough for it to redraw that part apparently
correctly, and that in 1.9.2c it just happened to be sufficiently
badly off to cause a coredump.

I won't be convinced that this rectangle isn't an abberation involving
some kind of incorrectly calculated quantities until someone shows me
how it was derived :-).

No, I don't think it is just a problem with the movement optimization.

What I'd really like is for one of the ncurses team to look over my
code and see what it ought to do and compare it with what it does.
If you point them to me I can explain the window/pad structures I'm
using, or answer their questions.

TERM=xterm in an 80x24 xterm (3.1.1-1 at the time, but it does it with
3.1.1-2 too).

In fact, I've just tried it (0.93.62 dselect, List, Redraw) in an
80x37 xterm (3.1.1-2) and I get a segfault.  If I try making my xterm
bigger one line at a time I find that the earlier-drawn rectangle
shrinks, and that I get a segfault when it has shrunk to nothing.

I can't reproduce the problem with a 132x43 Linux console with
TERM=console or TERM=linux.  TERM=con132x43 (the default for my 1.2.10
kernel) produces a string of messages about errors in terminal entries
and then appears to hang.

Ian.

Yes, I did see the rectangle in the upper left rendered before everything
else, and I also saw some lines cleared and than rendered with one space
in the left before being redrawn with their proper contents. I put that
up to strange movement optimization, but I'll take it up with them.
Rather than have them look at the whole of dpkg, can you put the relevant
fragments (refreshing windows, etc.) in a mail message along with questions?
You'll be more likely to get a response that way.

	Thanks

	Bruce
