Is it possible to read the version of a Google App Engine app at runtime?

Question

I have the version number set in my app.yaml to something like 'rc1'. I'd like to be able to read the current version for a status/health check URL. Is this possible?

Answer 1

Yes, take a look at http://code.google.com/appengine/docs/python/runtime.html#The_Environment there is a CURRENT_VERSION_ID variable that should tell you that.
