Hi --
Does gtk or pygtk use random numbers? I'm writing a program that uses random
numbers (from the stdlib random() function). The program's test suite needs to
have reproducible numbers, so one of the first things it does is to seed the
random number generator with a fixed value. However,
if the random number generator is seeded before the pygtk gui is built, the
random sequence begins at a different point than if the random number generator
is seeded after the gui is built. This indicates that building the gui
consumes some random numbers.
Where (and why) does pygtk/gtk/cairo/pango use random numbers? The gui doesn't
use them explicitly. If I knew which pygtk calls might use them, then I could
try to avoid those calls in the test suite, or at least ensure that they occur
before the random number generator is seeded.
Thanks,
Steve
