[Bug 1021783] [NEW] invalid behavior of curses.newpad().refresh()

[Launchpad Bug Tracker]

[Precise SRU Justification]

Valid python programs using the refresh method with the optional
arguments on a curses.newpad object will fail with a similar exception:

Traceback (most recent call last):
  File "newpad-refresh.py", line 10, in <module>
    pad.refresh(0, 0, 0, 0, size[0] - 1, size[1] - 1)
TypeError: refresh() takes exactly 0 arguments (6 given)

This breaks at least one of the examples in the python documentation and
I believe limits the usefulness of the pad object, since it allows one
to only display a portion of the pad with the refresh method.

[Fix]

Updates the ncursesw-include.diff patch with the version in quantal,
adding /usr/include/ncursesw/ to the search path in configure.in. This
allows the build scripts to find curses and builds the curses module
with the correct number of arguments to refresh.

[Regression Potential]

The regression potential should be minor since it just enables a build
option already enabled on the python2.7 package (as well as python3.2
and python3.3 in quantal).

[Test Case]

Running the following code with python3 will produce the above exception
without the patch, and prompt to "press q" to quit the script with the
patch.

import curses

try:
    screen = curses.initscr()
    curses.cbreak()

    pad = curses.newpad(10, 10)
    pad.addstr(0, 0, "press q")
    size = screen.getmaxyx()
    pad.refresh(0, 0, 0, 0, size[0] - 1, size[1] - 1)
    while True:
        ch = pad.getch()
        if ch == ord("q"):
            break
        pass
    pass
finally:
    curses.nocbreak()
    curses.endwin()
    pass

===============================================================================

There is invalid behavior of builtin curses module in amd64 version
python3.2.

>From API spec, `refresh()` method of a window object returned by
`curses.newpad(h,w)` should accept 6 arguments; `pad.refresh(pt, pl, st,
sl, sb, sr)`.

- http://docs.python.org/py3k/library/curses.html#curses.newpad

But python3.2 package in amd64 ubuntu precise does not accept arguments.


The code is worked well on python2.7 pakcage and self compiled python3.2.3.
There may be a package build problem at python3.2 or ncurses.
