I'm havign a small xmlrpc client, which works normally fine.
(xmlrpc via https)
Sometimes however I receive an Exception about an expat error.
The output, that I receive is:
File "C:\mycode\myrpcclient.py", line 63, in upload_chunk
rslt = myrpcclient.call()
File "C:\Python26\lib\xmlrpclib.py", line 1199, in __call__
return self.__send(self.__name, args)
File "C:\Python26\lib\xmlrpclib.py", line 1489, in __request
verbose=self.__verbose
File "C:\Python26\lib\xmlrpclib.py", line 1253, in request
return self._parse_response(h.getfile(), sock)
File "C:\Python26\lib\xmlrpclib.py", line 1387, in _parse_response
p.feed(response)
File "C:\Python26\lib\xmlrpclib.py", line 601, in feed
self._parser.Parse(data, 0)
ExpatError: syntax error: line 1, column 0
In order to continue debugging I'd like to dump the received http data,
which "C:\Python26\lib\xmlrpclib.py", line 601 tried to parse without
succes.
How can I do this?
a) Use the standard cgitb module (despite its name, it is useful outside
CGI scripts)
b) Use the tb module available from http://pypi.python.org/pypi/tb
Both provide a more verbose traceback, including local variables at each
execution frame.
c) Replace ("monkey-patch") the feed() method with a more debug-friendly
version:
def feed(self, data):
try:
self._parser.Parse(data, 0)
except xmlrpclib.expat.ExpatError, e:
e.args += (data,)
raise
xmlrpclib.ExpatParser.feed = feed
(Or perhaps set e.data = data)
d) In your exception handler, walk the traceback object until you reach
the feed() call, and inspect the corresponding tb_frame.f_locals
dictionary.
