Question

Can GAE be configured to bust me an email when there’s an error?

Answer 1

I think the best you can do is to have in your main function some code like…:

try:
  ...normal body of your main goes here...
except:
  from google.appengine.api import mail
  import sys

  mail.send_mail(sender="Your GAE App <[e-mail]>",
              to="You <[e-mail]>",
              subject="GAE App error",
              body="""
Your App Engine app raised an exception:
  %s
""" % sys.exc_info()[:2])

(of course, you can do better formatting on the exception information, etc, etc).
