1.6.3 Prerelease SDK Available

[Marzia Niccolai]

Hi,

The 1.6.3 prerelease SDKs are now available to download for Python and Java here: http://code.google.com/p/googleappengine/downloads/list

Please see release notes below.

-Marzia

Java Version 1.6.3
==================
- In the Admin Console, you can use the Traffic Splitting feature to send a
  certain percentage of traffic to a non-default application version. The
  traffic is split by either cookie or IP address.
- Emails from users that belong a Google Apps domain which are sent from a
  request originating from the same domain will have a DKIM signature applied to
  them.
- The instances screen in the Admin Console now has a button to shut down
  a specific instance.
- Each application log has a link to the instance that served the request. If
  the instance is no longer serving requests, a message will be displayed.
- The TaskQueue API now supports the ability to tag a Pull Queue task. You may
  then lease tasks by tag.
- Using Google Apps wildcard domain mappings, you can access alternate
  versions of your app via a custom domain.
- Pull Queue ACLs now support a "writer-email" role to support notifications
  of delivery of tasks to queues.
- Push and Pull Queues are now listed separately in the SDK development console.
- The DataNucleus Enhancer command line tool
  (com.google.appengine.tools.enhancer.Enhance) now supports the
  -enhancerVersion flag, which allow you to specify the version of DataNucleus
  with which to enhance your JDO/JPA classes.
- The dev appserver command line now supports the --generated_dir flag, which
  allows you to specify a directory in which to write files generated by the
  SDK.
- Fixed a StackOverflowError when using the Remote API.

- Emails from users that belong a Google Apps domain which are sent

  request originating from the same domain will have a DKIM signature

  them.

YES :)

[pdknsk]

PS. Just wanted to let you know, Marzia, that your release note posts
do lack line breaks when browsing with the old http://groups.google.com/group/
format, which makes the post practically unreadable. It's formatted OK
in the new http://groups.google.com/forum/ format. This isn't the case
when Ikai posts the release notes.

[Tom Willis]

What version of webob will be distributed with this? 

TIA

[pdknsk]

I have a question about this particular part: "which are sent from a
request originating from the same domain".

When I put a task (to send mail) on url="/mail/" it runs on
domain.appspot.com by default. Do I have to use url="http://domain.com/
mail/" then, or is this mapped automatically? Maybe I'm
misunderstanding this.

[GAE]

 

- The instances screen in the Admin Console now has a button to shut down
  a specific instance.
- Each application log has a link to the instance that served the request. If
  the instance is no longer serving requests, a message will be displayed.

I just deployed a java app. However i can't find that shut down button on the Instances page. Where is it supposed to be? 

[GAE]

I just deployed a java pp. However I can't see that shutdown button on the Instances page in the Admin Console. Where is it suppoed to be?

[Kaan Soral]

That description is very confusing, it would be great if someone could explain """Emails from users that belong a Google Apps domain which are sent from a request originating from the same domain """ in detail

[Joakim]

I too would like some clarification on what that part of the sentence
is means in practice.

These are some of the best features in recent releases:

- Datastore statistics now show the amount of storage used by application
indexes.

- The instances screen in the Admin Console now has a button to shut down
a specific instance.
- Each application log has a link to the instance that served the request. If

Can you please fix the following issue in 1.6.3 / Java:

 Internal exception during session-handling

I have enabled <async-session-persistence enabled="true" /> for performance reasons.

There seems to be problem / bug in the implementation?
I'm getting many ClassCastException "com.google.apphosting.runtime.jetty.DeferredSessionTasks$DeferredDelete cannot be cast to com.google.appengine.api.taskqueue.DeferredTask"?

Can somebody from Google please clarify this?

Sorry, this was my fault. This feature was meant to be removed from the notes that I posted, and aren't in the SDK.

But hopefully gives you a taste of things to come...

-Marzia

[Marzia Niccolai]

As an example, Let's say your application is installed on a Google Apps domain, eg 'googlemanageddomain.com' and a user accesses your app at 'app.googlemanageddomain.com' and signs in as 'us...@googlemanageddomain.com'.

When your application sends mail from 'us...@googlemanageddomain.com', it will be DKIM signed on the googlemanageddomain.com domain. If the user accesses your app viaapp.appspot.com, the mail will not be DKIM signed because the domain of the request does not match the domain of the signed-in user

-Marzia

[Joshua Smith]

If that's the only case where DKIM sigs happen, then please don't close the issue, because this is a weird edge case that doesn't really matter. (Sometimes I think google has some bizarre ideas about how their services are used.)

The case that matters is when the server is sending an administrative email, and we'd like the headers there to reduce the probability of those emails being tagged as spam.

In most cases, nobody at all will be signed in. These emails might be coming from a cron, or they might be happening as part of a registration process.

-Joshua

[pdknsk]

Hmmmm. So what if no user is signed in, but the systems sends mail on
behalf of a registered owner?

[Joakim]

What about emails sent from administrators of the app? For example,
when a user creates an account in my application, I send out an email
from no-r...@mydomain.com to my new user. Mydomain.com is the Google
Apps domain linked to my application. Will emails such as this one be
signed? Would this be affected by whether the email is sent using a
task queue or not, and if so, how?

[andrew]

This is precisely our case and what we wanted. Not a corner case.

Thanks.

[Joshua Smith]

Yes, this is exactly the case we need.

That registered owner, in our case, is not associated with the domain we are serving on. For example, the servers sends from the registered owner sup...@vendor.com, but the service is at coolstuff.vendor-services.com.

Hi Marce,

Most emails sent by my applications are sent from tasks and cron jobs.  Will they be signed ?

Thanx for your answer.

Sorry for the confusion; that case is also supported. As long as the
administrator's domain is a Google Apps domain and the domain's been
set up with a DKIM key, the mail will be signed.

[Moishe]

And one last point of clarification: the request won't influence
signing mail sent from an admin. The request could be user-initiated,
or initiated by a cron job or task queue.

[Francois Masurel]

Great news !

Thanx for your answsers Moishe.

François

[Robert Kluin]

Hey Marzia,
Hopefully it will find its way to the dashboard soon though.... ? :)

Robert

[pdknsk]

Great news indeed! This puts App Engine ahead of Amazon SES, at least
in the case of DKIM. Amazon does not sign mails automatically.

[Prashant Gupta]

- Using Google Apps wildcard domain mappings, you can access alternate
  versions of your app via a custom domain.

Does this mean that we will be able to map non-default version of an app to a custom domain ? 

[Joshua Smith]

Excellent.

Can you point me to docs on this bit:

[pdknsk]

It's quite simple.

Wow, traffic splitting is a really nice feature.

[PK]

Just as a positive data point it passed our python 2.5 app's regression test suite with usual performance characteristics.

I was hoping for some update on the status of python 2.7 (especially the SDK support) and SSL custom domain. Hopefully, next time...

[Thomas Wiradikusuma]

This might be a solution looking for problem for me, but I'm curious, why would I need that?

[Stuart Langley]

When you've made some modification to your app and you want to send it some percentage of your traffic to test how it behaves.

[Robert Kluin]

I totally agree this is an excellent feature. Should give us good
options for making the rollout of app updates a little safer.

Watch out though. The Channel API will be broken when you use traffic splitting!

See: http://code.google.com/p/googleappengine/issues/detail?id=6726

I hope they fix it before they launch 1.6.3

-Andrin

[Gopal Patel]

http://code.google.com/p/googleappengine/issues/detail?id=5770 

this is imp too in traffic splitting and in general multi-threading. 

[alex]

First off, awesome job.

There's one thing I'm not sure whether I'm missing something or doing it wrong but, a command like this one:

appcfg.py --oauth2 -V <some-version> request_logs APP_ROOT /tmp/requests.log

gives me an exception:

TypeError: object of type 'NoneType' has no len()

I noticed in appengine_rpc_httplib2.py, in Send(...) method args: 

"...payload: The body of the request, or None to send an empty request." And later, in the code (line 204), there's this:

headers['content-length'] = str(len(payload))

- and that's precisely where it gives the exception, because request_logs action eventually calls Send() with payload=None.

I know this is a prerelease so...  I was just wondering whether it's me doing something wrong.

PS I'm using python2.7. full traceback is attached.

Hi,

From the release notes:

- The DataNucleus Enhancer command line tool
  (com.google.appengine.tools.enhancer.Enhance) now supports the
  -enhancerVersion flag, which allow you to specify the version of DataNucleus
  with which to enhance your JDO/JPA classes.

How can I configure this flag in the plugin for the editor enhancer. It keeps copying and enhancing with the v1 libs.The error log of the debug server shows this exception due the misconfigured version:
java.lang.NoSuchFieldError: NUCLEUS_CONTEXT_LOADER
	at org.datanucleus.api.jdo.JDOPersistenceManagerFactory.<clinit>(JDOPersistenceManagerFactory.java:101)

thank you,Roberto
