Three tips for faster launchpadlib api clients

Wednesday, July 14th, 2010

Three tips from Leonard’s lightning talk in Prague about writing faster Launchpadlib API clients:

1. Use the latest launchpadlib. It gets faster from one release to the next. (The versions in the current Ubuntu release should be fine; otherwise run from the branch or the latest tarball.)

2. Profile:

    import httplib2
    httplib2.debuglevel = 1

will show each http request and response, so that you can see what’s taking time.

3. Fetch objects only once:

Don’t do this:

    if bug.person is not None:


    p = bug.person
    if p is not None:

In the first case, the client may fetch the Person object twice. (We may fix this in future.)
