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:=20
grouped =3D 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" =3D=3D 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?
