I'm using the xmlrpc MultiCall class pretty heavily in an application and every
time I've somehow caused an error in the xmlrpclib.py code, I get an exception
trying to raise the exception.
Here's the most recent example:
grouped = grouper(2, tuple(mc_result))
File
"/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/xmlrpclib.py",
line 1001, in __getitem__
raise Fault(item['faultCode'], item['faultString'])
Fault: <Fault 1: "<type 'exceptions.TypeError'>:'NoneType' object is
unsubscriptable">
I could understand if I was making some sort of coding error, then getting an
error, but the Fault object itself, whenever it is used, seems to be generating
some sort of new error either through its use, or, as above, the code
attempting to construct the Fault object fails.
The thing that's confusing about the above error is that there's a check, just
before the line of code that fails, that explictly checks whether the type of
"item" == type({}): so the code shouldn't even get called with "NoneType".
This all smells horribly like corrupt memory so I'm hoping someone on this list
has seen symptoms like this and can point me in the right direction to start
tracking this down.
This, btw, is a pretty simple, maybe 200 line pure Python app that is using the
XML-RPC interface, SQLite, and zlib functions.
I'm wondering if an earlier, uncaught error is actually setting this up but
it's only happened about 4 times, at completely unpredictable times, and
doesn't seem to be repeatable.
Definitely in line for best bug report ever.
Anyone seen this specific symptom, regardless of cause?
