RUNNING THE SDK
You can run the SDK with the following command:
dev_appserver.py [options] <application root>
Application root must be the path to the application to run in this server. Must contain a valid app.yaml or app.yml file.
Options: --address=ADDRESS, -a ADDRESS Address to which this server should bind. (Default localhost). --clear_datastore, -c Clear the Datastore on startup. (Default false) --debug, -d Use debug logging. (Default false) --help, -h View this helpful message. --port=PORT, -p PORT Port for the server to run on. (Default 8080)
--allow_skipped_files Allow access to files matched by app.yaml's skipped_files (default False) --auth_domain Authorization domain that this app runs in. (Default gmail.com) --auto_id_policy=POLICY Dictate how automatic IDs are assigned by the datastore stub, "sequential" or "scattered". (Default sequential) --backends Run the dev_appserver with backends support (multiprocess mode). --blobstore_path=DIR Path to directory to use for storing Blobstore file stub data. --clear_prospective_search Clear the Prospective Search subscription index (Default false). --clear_search_indexes Clear the Full Text Search indexes (Default false). --datastore_path=DS_FILE Path to file to use for storing Datastore file stub data. (Default /tmp/dev_appserver.datastore) --debug_imports Enables debug logging for module imports, showing search paths used for finding modules and any errors encountered during the import process. --default_partition Default partition to use in the APPLICATION_ID. (Default dev) --disable_static_caching Never allow the browser to cache static files. (Default enable if expiration set in app.yaml) --disable_task_running When supplied, tasks will not be automatically run after submission and must be run manually in the local admin console. --enable_sendmail Enable sendmail when SMTP not configured. (Default false) --high_replication Use the high replication datastore consistency model. (Default false). --history_path=PATH Path to use for storing Datastore history. (Default /tmp/dev_appserver.datastore.history) --persist_logs Enables storage of all request and application logs to enable later access. (Default false). --logs_path=LOGS_FILE Path to use for storing request logs. If this is set, logs will be persisted to the given path. If this is not set and --persist_logs is true, logs are stored in /tmp/dev_appserver.logs. --multiprocess_min_port When running in multiprocess mode, specifies the lowest port value to use when choosing ports. If set to 0, select random ports. (Default 9000) --mysql_host=HOSTNAME MySQL database host that the rdbms API will use. (Default localhost) --mysql_port=PORT MySQL port to connect to. (Default 3306) --mysql_user=USER MySQL user to connect as. (Default '') --mysql_password=PASSWORD MySQL password to use. (Default '') --mysql_socket=PATH MySQL Unix socket file path. (Default '%(mysql_socket)s') --require_indexes Disallows queries that require composite indexes not defined in index.yaml. --search_indexes_path=PATH Path to file to use for storing Full Text Search indexes (Default %(search_indexes_path)s). --show_mail_body Log the body of emails in mail stub. (Default false) --skip_sdk_update_check Skip checking for SDK updates. If false, fall back to opt_in setting specified in .appcfg_nag (Default false) --smtp_host=HOSTNAME SMTP host to send test mail to. Leaving this unset will disable SMTP mail sending. (Default '') --smtp_port=PORT SMTP port to send test mail to. (Default 25) --smtp_user=USER SMTP user to connect as. Stub will only attempt to login if this field is non-empty. (Default ''). --smtp_password=PASSWORD Password for SMTP server. (Default '') --task_retry_seconds How long to wait in seconds before retrying a task after it fails during execution. (Default '30') --use_sqlite Use the new, SQLite based datastore stub. (Default false) --port_sqlite_data Converts the data from the file based datastore stub to the new SQLite stub, one time use only. Requires enough RAM to hold all of the entities. (Default false) --[enable|disable]_console Enables/disables the interactive console. (Default enabled if --address is unset, disabled if --address is set)
USING THE SDK
For instructions on getting started with Google App Engine, please see the Google App Engine Getting Started Guide
https://developers.google.com/appengine/docs/python/gettingstarted
USING THE APP ENGINE LAUNCHER
The Windows and Mac OSX Python SDKs include an additional development tool called the App Engine Launcher. This tool provides a simple graphical interface to create projects, run them locally, and deploy them to Google's App Engine servers. It can be used in place of the dev_appserver and appcfg command-line tools.
The Windows SDK can optionally install a desktop short-cut during installation. If you are missing the short-cut, you can find the launcher in the launcher subdirectory of your App Engine installation. The default location is C:\Program Files\Google\google_appengine\launcher\GoogleAppEngineLauncher.exe
In Mac OSX, the Launcher is installed by dragging it out of the .dmg to a location specified by the user. The Launcher contains the SDK inside of it. A typical drag-install destination for the Launcher and SDK is /Applications/GoogleAppEngineLauncher.app
