[Python.NET] installation on GNU/Linux
Hi all,
I have installed pythonnet and thought it would be of interest
to send the outputs of the tests included in the library.

You're right -- the bug is indeed caused by the lack of a lock acquisition in
that code. Thanks for the tip. This item should be closed.

Note that to be thread-safe and reentrancy-safe you
also need to make sure that any managed code you have
that uses Python.Runtime objects or methods is acquiring
the Python lock first. For example:
public class Example {
public static int MethodThatCallsPython() {
// have to acquire the GIL to safely call back into
// Python!!
IntPtr state = PythonEngine.AcquireLock();
PythonEngine.RunSimpleString("print 'hello'");
// done using python for now, so release the GIL...
PythonEngine.ReleaseLock(state);
}
}
Forgetting to manage the lock around a callback into Python
is almost certain to cause a NullReferenceException (because
there will be no valid thread state when the callback is
made).

There seems to be some sort of strange crash occurring when importing CLR in
the interactive prompt. It doesn't occur when executing a script from a file
or in shells like PyCrust. Also, it does not happen at all in Python
2.3/PythonNET beta 3.
Importing CLR seems to wreak havoc with the interpreter:

hello, I have skimmed the test case, and removed all dependancies toward
the Simpy framework.
Now it crashes once the python main loop is finished. If I comment out
the code used to pass a python function as a delegate to the C# frame,
it doesn't.
here is the code:
#test to show problem.
import sys,time
sys.path.append('.')
from CLR.System.Reflection import Assembly
a = Assembly.LoadWithPartialName("testpython")
from CLR.testpython import MainForm, TestDelegate
def test():
return "hop"
if __name__ == '__main__':
form = MainForm.GetInstance()
form.TestDelegateProperty = TestDelegate(test)
form.Start()
time.sleep(1)
print "done"
Stan.
the CLR sources are the same.
Contact me if any more info is needed.

hello,
the following application (python/C#) is working properly, when I do not
run simpy, a python framework. Once I enable, I get an immediate crash.
See enclosed for runnable/compilable example. (run "python test.py"). To
run, it needs the Simpy framework, GPL, that you can get there:
http://simpy.sourceforge.net/
Simpy makes heavy uses of the "yield" construct.
as soon as I uncomment that line in the script:
#simulate()
I get an immediate crash. I see no reason for this crash.
Stan.
