Hey everyone, cPickle is raising an ImportError that I just don't quite
understand. Before I paste the code, let me explain the application.
Basically the part of the application that failed is a function that
loads a list of objects from a file using cPickle. This list is a queue
of requests. I've done some research and it looks like cPickle tries to
load some modules as some kind of test. From what I can tell the module
that cPickle is trying to load is a concatenation of the module that it
exists in and part of the string that was sent in the orignal request.
It looks like something where memory is getting overwritten, but I'm not
really doing anything too fancy, so i'm not sure how to approach this
problem. I'm using python2.2. Does anyone know how I might go about
trying to troubleshoot something like this? Is there a good tool or a
better method of error handling I can use to try and track this down?
Or is it better to give up troubleshooting and just upgrade to 2.4?
Here's the code where the error occured:
def initQueue():
global masterQueue
try:
queueFPtr = open("/home/build/bin/resourceManager/queue.rm","rb")
except IOError:
raise ResourceError,"Error Opening Queue for Reading"
except:
traceback.print_exc()
raise ResourceError, "Unknown Error Opening Queue"
try:
pickledList = cPickle.load(queueFPtr)
except EOFError:
masterQueue = [[],[],[]] #empty file, set to empty list for construction
#there exist 3 blank lists in the master list, these list refer to
various priorities 0, 1, and 2
queueFPtr.close()
return
except:
traceback.print_exc()
raise ResourceError, "Unknown Error loading Queue"
queueFPtr.close()
masterQueue = pickledList
return
Here's the traceback:
