Hey everyone, Prerelease SDK 1.5.0 is ready for download! There are a ton of bug fixes in this release as well as some pretty big features. Check it out. You can get the SDKs here:
http://code.google.com/p/googleappengine/downloads/list The release notes are below. You'll notice that they're much longer than usual. We've listed out many of the bugs in the public issues tracker we've addressed. Python ============================== - Support for Backends which allow developers to create infrastructure components that complement the existing dynamic apps which App Engine already provides. Instances of a backend can maintain state, be addressed individually, and are not subject to per-request time limits. They can also be configured to consume more memory and CPU than ordinary dynamic instances. - Task Queues support pull mode, allowing for more control over task queue work rates. To use pull queues, include the 'mode' argument in your queue.yaml. - Pull queues are supported by a REST API, allowing access from outside App Engine. To use the REST API, you must also include a valid ACL section specifying which users can lease tasks from the pull queue. - Task Queue payload limits have been increased. Push queues now support 100KB per task, pull queues support 1MB per task. Within App Engine, the new limit is 32 MB per batch of tasks. With the REST API the limit is 1 MB per batch. - HTTP request and response sizes have been increased to 32 MB. - We have removed the rate quotas for requests, datastore operations, memcache operations, and image API operations. Resource quotas still apply. - When creating new applications, developers will now see the High Replication Datastore as the default configuration option. Developers that still wish to use the Master/Slave configuration must explicitly choose this option at application creation time. - The Task Queue maximum configurable processing rate has been increased to 500/s. - All application Owners, as listed in the Admin Console, can download the app's code, unless code download is disabled for the application. - Added db.py support for making calls to the datastore asynchronously. Available functions are get_async(), put_async(), delete_async(), allocate_ids_async(). Call get_result on the return value of asynchronous datastore functions to block on the call. - Metadata queries can now get all namespaces, kinds, and properties in a given range. - The Testbed API now supports the Channel API. - Users can provide Django settings to be loaded in webapp's django_setup. - Modified Dashboard latency graphs to indicate they only include dynamic requests. - Fixed an issue where Federated User data didn't survive a get-put-delete operation cycle. - Fixed an issue where metadata queries did not support unicode characters. - Fixed an issue where HTTP headers could contain new line characters. - A warning message is shown when the Python version used to run the SDK is different than the Python version used in production. - Fixed an issue with Federated Users causing the Admin Console dataviewer to fail. http://code.google.com/p/googleappengine/issues/detail?id=384 - MacOS and Windows style newlines are now supported for logging in the SDK. http://code.google.com/p/googleappengine/issues/detail?id=560 - Fixed an issue where sending mail with smtp_host set did not work. http://code.google.com/p/googleappengine/issues/detail?id=626 - Fixed the file permissions for appinfo_errors.py and appinfo.py in the SDK. http://code.google.com/p/googleappengine/issues/detail?id=725 - Fixed an issue deploying an app with version set to 0. http://code.google.com/p/googleappengine/issues/detail?id=735 - Fixed an issue where the SDK allowed GET or DELETE with a body, which does not work in production. http://code.google.com/p/googleappengine/issues/detail?id=983 - Fixed an issue where URLFetch/urllib did not work with MacOS and Python 2.6.0-2.6.3. http://code.google.com/p/googleappengine/issues/detail?id=985 - Fixed the an issue in the SDK where the mail body was incorrectly generated when the sendmail option was enabled. http://code.google.com/p/googleappengine/issues/detail?id=1061 - Fixed an issue in the SDK dataviewer where editing a ListProperty(db.Category) resulted in a BadValueError. http://code.google.com/p/googleappengine/issues/detail?id=1139 - Fixed an issue in the SDK where the signal module could be imported, as it is not supported. http://code.google.com/p/googleappengine/issues/detail?id=1150 - Improved support for reserving an app id that is a canonicalized version of a user's Gmail address. http://code.google.com/p/googleappengine/issues/detail?id=1196 - Added a more useful error messages for unavailable App Ids. http://code.google.com/p/googleappengine/issues/detail?id=1303 - The SDK now uses hashlib instead of sha.
