Hi,
What happens if I do the following?
using namespace boost::python;
import( "__main__" ).attr( "new_global" ) = 40.0f;
import( "__main__" ).attr( "another_global" ) = 100.0f:
My main concern here is performance. I'm wondering if each call to
import() results in a disk query for the script in question and loads it
from there. I'm also wondering if the second import() above will simply
read from a memory cache or something.
As the above code is only a wrapper around the Python runtime, you are
really asking about how Python handles repeated 'import' calls. I'm
pretty sure importing a module while it is already imported will do
(almost) nothing. However, I'm not sure whether a module is actually
unloaded as soon as the last reference goes away (such as after the
first line above is completed), so I can't give a definite answer.
I'm sure you'll get better answers when asking on a Python forum directly.
Regards,
Stefan
