Package: ncurses
Version: 1.8.7-1

The `search' option in dselect 0.93.35 exhibits bug(s) in ncurses's
wgetnstr routine.

It appears always to return ERR, or to set the returned string to the
empty string (it's not clear which).  When I try it I'm able to type
much more into the prompt than I'm supposed to be able to - according
to the manpage I should only be able to type as many characters as the
size I've specified (which is 49 in this case).

Alternatively, perhaps I shouldn't really be seeing those characters;
I turned echo on with echo() before the call to wgetnstr because
otherwise I didn't see any output at all.  The manpage is unclear
about what effect the echo setting has on the behaviour of wgetnstr.

Furthermore, when run inside a mono xterm (xbaseR6 3.1.1-7), it does
something nasty to the xterm and/or ncurses's state, so that the arrow
keys and so forth don't work any more.  This last problem doesn't
appear on a Linux console (1.2.0) with TERM=linux.

Ian.

This appears to work in ncurses 1.9.0c-0.

The behaviour here is now somewhat better, but still odd.  It issues a
beep not when you fill the buffer, but when you first delete a
character after having filled it.

The documentation is still unclear about this.

This is still the case in an xterm.  I haven't tested it on a VC.

Well, it IS trying to beep, but since output does not get flushed the
bell sound later when something causes the flush. I'm not quite sure
why backspacing flushes output whilst beep does not. Adding wrefresh(win)
after beep() in lib_getstr.c will make it work but is not really a solution.

That's because SVR4's documentation is also unclear. I guess we could
document the extisting behavior.

I don't know where Eric gets his definitions for xterm, but my xterm has
different F1-F5, both HOME and END send ^[O^@.
The arrow keys do work though.

The subject line of your first message started with `Re: Re:' - see
the tracking system logs.  The bug processor only strips one `Re:'.

My (Debian) xterm sends ESC O M-C-p (ie, 27 79 144) for END, and ESC O
NUL (27 79 0) for HOME.
