New issue 43 by mefisk: wimpiggy: overflow error breaks WM_TAKE_FOCUS
http://code.google.com/p/partiwm/issues/detail?id=43
In send_wm_take_focus() in lowlevel/__init__.py, we pass "time" into the
pyrex code where it gets used to initialize a signed 32-bit
XClientMessageEvent data. This value comes from the X server time, which
is 32-bit unsigned. On my system (xvfb from X.org 1.9.0 on a 32-bit
system) my server time is a value that does not fit in a 32-bit signed
quantity and so Python raises an overflow error.
The ICCCM documentation glosses over this problem. I poked around for
other C implementations and I _think_ that people just usually cast the
uint32 to the long. The attached patch does that in python (which isn't
easy, but this is a known idiom) and fixes the problem. Perhaps this
should be in pyx code....
