Prerelease SDK 1.4.2 is available for download

[Ikai Lan (Google)]

Hey everyone, I just wanted to post that the prerelease SDKs for 1.4.2 are now available for early testing:

http://code.google.com/p/googleappengine/downloads/list

Highlights of this release:

- Lots of XMPP improvements

- Prospective Search API (formerly known as Matcher API) now available to everyone

- Lots of improvements to task queues

- vacuum_indexes in Java SDK

Full release notes are below. As a reminder, the backend portions of 1.4.2 have not been pushed yet, so they won't likely work (though vacuum_indexes for Java should be working). Download and enjoy!

Python

-------------

- The XMPP API was updated to include presence and allow subscriptions.

- The Task Queue now supports programmatic deleting of tasks.

    http://code.google.com/p/googleappengine/issues/detail?id=2588

- The maximum rate per queue at which tasks are processed has been increased to

  100 tasks per second.

- The maximum number of concurrent requests for a single queue can be specified

  in the application's queue.yaml. This provides an additional easy-to-use form

  of rate limiting. The current number of running tasks is also displayed in

  the Admin Console.

- Metadata queries in the Datastore now support cursors.

- Admin Console logs viewer now displays time as YYYY-MM-DD HH:MM:SS.mmm.

- Added a warning when an admin tries to upload a queue.yaml where the number

  of new queues and the number of disabled queues exceeds 100.

- Django 1.2.4 is available via use of the use_library() declaration. This

  version of Django has also been added to the Python SDK.

- The Prospective Search API (formerly named the Matcher API) is available for

  use by all applications. Applications will be limited to a maximum of 1000

  subscriptions during the experimental release.

- Added builtin support for the deferred library.

- If Python Precompilation fails, an error will be printed but the app will

  still be uploaded.

- Added a --disable_sdk_update_check command line flag to the dev_appserver.

- The Mail API added KML and KMZ files as allowed attachments.

- Fixed an issue where the datastore copy functionality did not work if writes

  were disabled on the source application.

- Fixed an issue where mail from @appid.appspotmail.com did not work when

  sending mail to app admins.

- Fixed an issue where the dev_appserver URLFetch API limit was 16MB. It is now

  32 MB to match production.

- Fixed a zipimport issue on Windows which was not working due to path

  separators.

    http://code.google.com/p/googleappengine/issues/detail?id=2086

- Fixed an issue where the SDK did not enforce the 100 task limit for the Task

  Queue.

    http://code.google.com/p/googleappengine/issues/detail?id=3296

- Fixed an issue where Query.order() was broken for properties with the 'name'

  attribute.

    http://code.google.com/p/googleappengine/issues/detail?id=3693

- Fixed an unhelpful error message in the Python namespace_manager.

    http://code.google.com/p/googleappengine/issues/detail?id=3931

Java

---------

- You can now vacuum datastore indexes with the Java SDK.

- The XMPP API was updated to include presence and allow subscriptions.

- The Task Queue now supports programmatic deleting of tasks.

    http://code.google.com/p/googleappengine/issues/detail?id=2588

- The maximum rate per queue at which tasks are processed has been increased to

  100 task per second.

- The maximum number of concurrent requests for a single queue can be specified

  in the application's queue.xml. This provides an additional easy-to-use form

  of rate limiting. The current number of running tasks is also displayed in

  the Admin Console.

- Metadata queries in the Datastore now support cursors.

- Admin Console logs viewer now displays time as YYYY-MM-DD HH:MM:SS.mmm.

- Added a warning when an admin tries to upload a queue.yaml where the number

  of new queues and the number of disabled queues exceeds 100.

- Added a putIfUntouched() method to the Memcache API.

    http://code.google.com/p/googleappengine/issues/detail?id=2139

- Added JAX-WS support for writing SOAP clients and SAAJ support for writing

  SOAP servers. JAX-WS for SOAP servers is not yet supported.

- The Mail API added KML and KMZ files as allowed attachments.

- Fixed an issue where mail from @appid.appspotmail.com did not work when

  sending mail to app admins.

- Fixed an issue where the SDK did not enforce the 100 task limit for the Task

  Queue.

    http://code.google.com/p/googleappengine/issues/detail?id=3296

- Fixed an issue where the Java SDK URLFetch did not support 32MB response

  sizes.

    http://code.google.com/p/googleappengine/issues/detail?id=4215

- Fixed an issues where <jsp-file> mappings in web.xml were broken.

    http://code.google.com/p/googleappengine/issues/detail?id=4216

What about Java The Prospective Search API ?

[sandeep Koduri]

Hello Ikai,

Thanks for the updates, 

Deleting tasks progarmatically will help a lot.

about xmpp, From the api code we are able to understand the send presence can show to a particular Jid as mentioned by us,

that will be very cool,

And what dose ' allow subscription ' mean.

Thanks for any reply.

Hello Ikan,

The doc on the App Engine wiki at http://code.google.com/p/googleappengine/wiki/WillItPlayInJava needs an update as regards to the non-supported APIs and technologies. JAX-WS is now supported.

Sorry if this is a stupid question: Is there a pointer to the
prospective search/matchin API?

Cheers, R.

[Ikai Lan (Google)]

Docs usually aren't ready by the time prerelease SDKs are, but they are usually ready by the time the full SDK is released. Here are my old notes on the Prospective Search API (formerly known as the Matcher API):

http://groups.google.com/group/google-appengine/browse_thread/thread/5462e14c31f44bef

It's looking like this won't make it, however, so look for it in an upcoming release.

"bummer" = instant feedback

looking forward to it when it is available though

[Lior Harsat]

Hi Ikai,

I have been testing the SDK and I found one bug which seems critical.
When I call the URLFetchService.fetch API with a https URL I get a
javax.net.ssl.SSLHandshakeException.
for example when I fetch "https://spreadsheets.google.com/feeds/
list/...." I get
javax.net.ssl.SSLHandshakeException: Could not verify SSL certificate
for: https://spreadsheets.google.com/feeds/list/...
When I switch back to an older SDK this doesn't happen.

Is there a "Help us test Prerelease SDK 1.4.2" thread I can post this
to?
Can anyone confirm this bug reproduces?

Thanx, Lior

This is caused because:

If you communicate with HTTPS or FTPS servers using certificates that are

signed by CAs present in the bundle, you can be sure that the remote server

really is the one it claims to be.

I really don't know what lib uses java, but you should check how to add the cert (of the https URL  your trying to fetch) to your list of "Nice" CA. You can check this to see how to extract the cert: http://curl.haxx.se/docs/sslcerts.html

But you should investigate further to see how to add it to your CA bundle.

SDK 1.4.2 + docs are available for download, but live docs are not updated (and no official announcement in this forum) yet.

1.4.2 is live in production (http://con.appspot.com/console/ says Google App Engine/1.4.2)

We're in a transitional state where we're still pushing 1.4.2. If you can wait until the official blog post/groups post goes live, you might save yourself a few headaches.

I have the same problem with spreadsheets, though not with feeds such
as "docs.google.com/feeds/default/private/full" it seems. Only
occuring when I tried 1.4.2

[David Mora]

just out of curiosity:

is it me or i see some implementations of GSA on the Matcher Service? :)
