[Python.NET] BUG in python delegates returning int called from C#

26 Aug 2005

      hello,

the following code may point to a bug in delegates implementation

python:

def stringFunc():
  return "Hello world"

def intFunc():
  return 0

test.AnotherClass.SetStringDelegate (test.StringDelegate(stringFunc))
test.AnotherClass.SetIntDelegate    (test.IntDelegate(intFunc))

t = test.MyClass()
t.Dump(2)

C#:

public static void Dump ()
    {     
      Console.Out.WriteLine (stringDelegate() + " " +
intDelegate());                           
    }

see output:

[Debug]> python test.py
Got : 2
Hello world 80098912
Hello world 80099400
[Debug]>

--> As we see, the call to intDelegate() returns unspecified
results...whereas it should return 0.....

Full test case below.
