Hacking Google App Engine (follow-up)

As mentioned last Tuesday at the meetup, I want to make the sources for this presentation easy to access. This brief post contains all the data necessary.

First, let's start with the basics:

• Here is the presentation in pdf form.
• Hack #1: collecting profiling data
• Hack #2: per entity audit data

As far as the program I used to demonstrate the hacks:

• The program I modified was the simple ajax chat sample.
• To be able to do low-level queries on the store, I integrated the interactive ajax shell.
• The final version can be downloaded here.

To try out the different hacks in a local dev environment,

• go to http://localhost:8080/ on your local machine and enter a couple of chats
• then, go to http://localhost:8080/stats to see the mini statistics
• then, go to http://localhost:8080/shell and execute the following script(hitting Ctrl-Enter after each line):
  from google.appengine.api import datastore
  datastore.Query('Greeting').Get(100)

Happy Hacking :-)
