Diagnostic Handler not working in API Bindings

[Rodolfo Ochoa]

When I run this code in python the diagnostic handler method is never called.

class MyDiagnosticHandler(zorba_api.DiagnosticHandler):
  def error(self, *args):
    print "Error args: ", args

def test(zorba, diagnosticHandler):
  try:
    xquery = zorba.compileQuery("1 div 0", diagnosticHandler)
    print xquery.execute()
  except Exception, e:
    print "Cought error: ", e
  return

store = zorba_api.InMemoryStore_getInstance()
zorba = zorba_api.Zorba_getInstance(store)
diagnosticHandler = MyDiagnosticHandler()

print "Running: Compile query string using Diagnostic Handler"
test(zorba, diagnosticHandler)
print "Success"

zorba.shutdown()
zorba_api.InMemoryStore_shutdown(store)

Paul, could you please look into this?

[Paul J. Lucas (paul-lucas)]

Since I know nothing about Python, please specify exactly how to reproduce this bug. I assume copy/paste the above code into something like a test.py file, but what do you do after that? How do you tell python about Zorba? How do you run the test?

[Rodolfo Ochoa (rodolfo-ochoa)]

You need to setup the API Binding for Python... install SWIG, Python libs and rebuild, CMAKE should be able to detect both... then after rebuild, you should have the python binding and you'll be able to execute this example.

[Paul J. Lucas (paul-lucas)]

Execute the example *how*? What do I type? Again, I know nothing about python.

Also, when you add a note, you need to assign the bug back to me so I see the note. I waited all morning for you to give the note that you did. I only discovered it by manually checking the bug.

call python with the script filename like:
>python example.py

[Rodolfo Ochoa (rodolfo-ochoa)]

you can also verify with CTest
>ctest -V -R python

[Paul J. Lucas (paul-lucas)]

The file test.py was added: Test file.

[Paul J. Lucas (paul-lucas)]

Since sourceforge and the browser don't maintain whitespace for code and since Python is particular about whitespace, I've attached the code I'm using. Please review. If it is NOT correct in terms of indentation (or anything else), please edit it and attach a NEW file as test2.py.

When I run this, I get:
Fatal Python error: PyThreadState_Get: no current thread
