Debugging cookielib.CookieJar

I've got a unit test suite which instantiates an HTTP client to test our server. We depend on session cookies. To handle this, I've got: def setUp(self): self.cj = cookielib.CookieJar() self.opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(self.cj)) This works fine

Another win for profiling.

It's often said that you shouldn't try to guess what's slow, but use profiling tools to measure what's slow. I had a great example of that yesterday. We have some web server code that does a big database (MongoDB) query and some post-processing of the data in python. It worked fine in testin

Wow. I was going to suggest using the unix command-line sort utility via popen() or subprocess. My arguments were that it's written in C, has 30 years of optimizing in it, etc, etc, etc. It almost certainly has to be faster than anything you could do in Python. Then I tried the experiment.
