Running web2py as a WSGI application in GAE with Python2.7

Question

How to configure Web2Py [Version 1.99.4 (2011-12-14 14:46:14) stable] to run as a WSGI application on GAE using Python2.7.2 ?

Currently my app.yaml file looks like this:

 # For Google App Engine deployment, copy this file to app.yaml # and edit as required # See http://code.google.com/appengine/docs/python/config/appconfig.html # and http://web2py.com/book/default/chapter/11?search=app.yaml application: my-app-name version: 1 api_version: 1 # use this line for Python 2.5 # # runtime: python # use these lines for Python 2.7 # upload app with: appcfg.py update web2py (where 'web2py' is web2py root directory) runtime: python27 threadsafe: true # true for WSGI & concurrent requests (Python 2.7 only) default_expiration: "24h" # for static files handlers: - url: /(?P<a>.+?)/static/(?P<b>.+) static_files: applications/\1/static/\2 upload: applications/(.+?)/static/(.+) secure: optional - url: /favicon.ico static_files: applications/welcome/static/favicon.ico upload: applications/welcome/static/favicon.ico - url: /robots.txt static_files: applications/welcome/static/robots.txt upload: applications/welcome/static/robots.txt - url: .* script: gaehandler.py # CGI # script: gaehandler.wsgiapp # WSGI (Python 2.7 only) secure: optional admin_console: pages: - name: Appstats url: /_ah/stats skip_files: | ^(.*/)?( (app\.yaml)| (app\.yml)| (index\.yaml)| (index\.yml)| (#.*#)| (.*~)| (.*\.py[co])| (.*/RCS/.*)| (\..*)| (applications/(admin|examples|welcome)/.*)| ((admin|examples|welcome)\.(w2p|tar))| (applications/.*?/(cron|databases|errors|cache|sessions)/.*)| ((logs|scripts)/.*)| (anyserver\.py)| (web2py\.py)| ((cgi|fcgi|modpython|wsgi)handler\.py)| (epydoc\.(conf|css))| (httpserver\.log)| (logging\.example\.conf)| (route[rs]\.example\.py)| (setup_(app|exe)\.py)| (splashlogo\.gif)| (parameters_\d+\.py)| (options_std.py)| (gluon/tests/.*)| (gluon/(rocket|winservice)\.py)| (contrib/(gateways|markdown|memcache|pymysql)/.*)| (contrib/(populate|taskbar_widget)\.py)| (google_appengine/.*)| (.*\.(bak|orig))| )$ builtins: - remote_api: on - datastore_admin: on - appstats: on - admin_redirect: on - deferred: on 

But when trying to download the application using the AppEngine SDK for Python (v1.6.3) :

I get the following error:

 2012-03-10 12:37:01 Running command: "[u'C:\\Python27\\pythonw.exe', 'C:\\Program Files\\Google\\google_appengine\\dev_appserver.py', '--admin_console_server=', '--port=8088', u'E:\\Programming\\Python\\web2py']" WARNING 2012-03-10 07:07:18,851 rdbms_mysqldb.py:74] The rdbms API is not available because the MySQLdb library could not be loaded. ERROR 2012-03-10 07:07:20,483 dev_appserver_main.py:581] Fatal error when loading application configuration: Invalid object: threadsafe cannot be enabled with CGI handler: gaehandler.py in "E:\Programming\Python\web2py\app.yaml", line 90, column 1 2012-03-10 12:37:20 (Process exited with code 1) 

Also, is there anything else I should know about threadsafe WSGI applications, given that I'm new to this? Do I need to make any changes to my application in order to run it as one?

Comment out the line gaehandler.py and uncomment the line gaehandler.wsgiapp.
