RE: [Zope] Help Debugging External Methods
the Python debugger "pdb" It's a Python module used to debug Python programs. It can set breakpoints, single step and print expressions. It is activated automatically, when you start "ZPublisher/Test.py" with the "-D" option. Usually, I do not use it this way, however, as it takes too long, before I reach the interesting point. Instead, I use: import pdb; pdb.set_trace() at the point in Python code, where I want to get control. Then I use "Test.py" without "-D".

RE: [Zope] Help Debugging External Methods
I do pretty much the same things myself. I assign sys.stderr = sys.stdout, then I create my own log file object from a module I wrote a few years ago, and then assign something like sys.stderr = self.logObj. That works well for any errors that occur after those assignments have occurred but doesn't do much for anything that happens earlier. I also run the python code outside of Zope to get it all working. It's just a pain when I have to make some minor change in the Zope to External Method logic and it breaks. That's where I start to lose it some in the debugging. Using something like: import sys, traceback, string try: trysomething() except: type, val, tb = sys.exc_info() sys.stderr.write(string.join(traceback.format_exception(type, val, tb), '')) del type, val, tb ...helps, but even with that I seem to get errors that I just can't seem to catch and report properly. I'm not sure what you are referring to with "...the Python debugger "pdb"...". I've never used it. Thanks for your help, Robert J.
