Pymongo get eval results

[Joel]

I'm using pymongo to write a program that takes a script file and sends it to my MongoDb server. My question is, does the eval method return anything containing the results from running the script code? Is there something else I can do to get all the past query results? Here is the code running the script.

def processScript(self, filename):

self.client = pymongo.MongoClient('localhost')

db = self.client.test

data = ""

# read the .js file into a string

with open(filename) as f:

data = data + f.read()

try:

# Pass the string to mongodb be evaluated

db.eval(data)

except Exception as e:

# TODO: Find out the actual exception that would be thrown.

print "Error running script \'%s\': %s" % (filename, e)

sys.exit()

I highly recommend that you do not use eval. First of all, the performance of eval is poor. A global lock is taken while the javascript is being evaluated, blocking other operations. Secondly, when using authentication you must have essentially 'root' roles and be authenticated to the admin database to use eval at all.

Why are you reading operations out of a JSON file? Could they be translated to Python?
