Subject: ncurses: notimeout() does not behave as documented

Date: Fri, 20 Nov 2015 10:24:00 +0000

Source: ncurses
Severity: normal

Dear Maintainer,

According to the inopts(3ncurses) man page, calling:

    notimeout(win, TRUE)

for an ncurses window should disable the timer for interpreting input
escape sequences in wgetch(). The expected result, therefore, is that
this would remove the one-second delay in registering the user hitting
ESC when keypad(win, TRUE) has also been called.

This is not the case; the one-second delay remains in force, despite
seeming to be ludicrously long even for a physical terminal on a 9600
baud serial line (approx. 1ms per character), let alone a terminal
emulator.

This has been fixed in the 20151128 upstream patchlevel, according to
the NEWS file:

,----
| 20151128
|     	+ add missing assignment in lib_getch.c to make notimeout() work
|     	  (Debian #805618).
`----

I had forgotten about this bug and so missed to close it
debian/changelog.

Cheers,
       Sven
