[XML-SIG] Failure when profiling XML processing (original) (raw)

I'm trying to profile some code that parses an XML file. (I've never used a profiler or done optimizations (this is my first big project) before.) Here's what happens:

--- snip ---

profile.run("import testCardSet; testCardSet.printAll()") Traceback (most recent call last): File "", line 1, in ? File "/usr/lib/python2.2/profile.py", line 71, in run prof = prof.run(statement) File "/usr/lib/python2.2/profile.py", line 404, in run return self.runctx(cmd, dict, dict) File "/usr/lib/python2.2/profile.py", line 410, in runctx exec cmd in globals, locals File "", line 1, in ?

--- snip ---

(I know that wrapped funny; hope it's understandable)

I don't really know, but this looks like a bug to me. The code runs fine outside of the profiler. I'll submit a bug report to SourceForge if it is indeed a bug in the XML tools.
