slice2py --no-package problem

mmarquar

The following code worked under ice 3.3 but under 3.4 fails with an ImportError. According to the manual thsi should still work.

ImportError: No module named example

cat example.ice
module example
{
    enum Useful
    {
       A,
       B,
       C
    };
};
slice2py --no-package example.ice

cat test.py
import Ice
import example_ice
import example

python test.py

I have tested this under both linux and OS X. Is anyone else seeing the same problem?!

Hi,

We did make some changes in Ice 3.4 to address the issue reported here that would cause the behavior you are seeing.

You can solve this by creating example.py that contains the following:

# example.py
import example_ice

Another option is to call the undocumented function Ice.updateModules:

# test.py
import Ice
import example_ice
Ice.updateModules()
import example

Of course, there's the usual caveat that a subsequent Ice release can break applications that use undocumented APIs.

Regards,
Mark

Could you update the slice2py documentation accordingly please.
The existing documentation hasn't been updated to reflect the changed behaviour.
It should probably go into the changelog as well as it breaks 3.3 code.

I don't quite understand how the first example would work any different to the way it is broken now.
I have nested modules and do the following at the moment as part of a python module which contains the generated _ice.py files.

from . import MyInterfaces_ice
import a.b.c
from a.b.c import ExampleInterface
