Bug in handling class objects #5

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. installed apptrace as per the instructions in wiki
2. profile a gae application with class objects

The following error is encountered 
File 
"/Library/Python/2.6/site-packages/apptrace-0.2.1-py2.6.egg/apptrace/middleware.
py", line 116, in wsgi_app
    if record: recorder.trace()
  File "/Library/Python/2.6/site-packages/apptrace-0.2.1-py2.6.egg/apptrace/instruments.py", line 207, in trace
    obj_type = obj.__class__.__name__
AttributeError: class rnapar_2 has no attribute '__class__'

What is the expected output? What do you see instead?
Instead of showing the memory usage, an error is raised when  a class object is 
used in the code

What version of the product are you using? On what operating system?
OS X 10.6.4
Python 2.6
Google App Engine 1.4

Please provide any additional information below.
The following is the traceback

Fixed in 0.2.2 release. This exception was due to a bug when tracing old style 
class objects.
