App Engine 1.6.1 Released!

[Ikai Lan (Google)]

Hey everyone,

App Engine 1.6.1 has been released! Get it while it's hot! You can view the blog post below:

http://googleappengine.blogspot.com/2011/12/app-engine-161-released.html

The "Downloads" page in the documentation will be updated shortly. If you want to beat everyone else to it, you can download the SDKs and installers directly from here:

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

I've posted the release notes below for your convenience.

Python Version 1.6.1 - December 13, 2011

• You can now configure Frontend Instance Classes from your Admin Console's application settings page. Three classes are available, with increasing memory, CPU limits, and associated cost. By default, all applications use the basic frontend instance setting of 128MB memory and 600MHz CPU.
• We've added new functionality to the Log API that will allow you to read your application's logs programmatically.
• We are releasing an experimental Conversion API that will allow you to convert between document types including .doc, .html, .pdf, images using OCR, and more.
• The High Replication Datastore migration utility is now available as a GA feature, and is no longer experimental.
• The ext.db API query functions (run, fetch, count, get) now accept the keyword arguments: deadline, read_policy, prefetch_size, batch_size, limit, offset, start_cursor, end_cursor, keys_only. It is recommended that developers use Query.run() with a limit or batch_size instead of Query.fetch() when iterating over results.
• The ext.db API model functions (get, put, delete, allocate_ids) now directly accept the keyword arguments: deadline, read_policy
• The Blobstore API now supports the multiple="true" attribute to the HTML input tag.
• Fixed an issue logging unicode objects in the SDK.
• Fixed an issue with the dev_appserver where HTTP HEAD always returned content-length: 0.
• http://code.google.com/p/googleappengine/issues/detail?id=2000
• Fixed an issue in the SDK where importing Crypto.Util.Counter caused an ImportError?.
• http://code.google.com/p/googleappengine/issues/detail?id=4168
• Fixed an issue where the SDK didn't work with virtualenv.
• http://code.google.com/p/googleappengine/issues/detail?id=4339
• Fixed an issue where cached static files served to IPs on the DoS blacklist consumed bandwidth quota.
• http://code.google.com/p/googleappengine/issues/detail?id=4607
• Fixed an issue that was causing slow serving of requests in the SDK.
• http://code.google.com/p/googleappengine/issues/detail?id=6005
• Fixed an issue where the Channel API didn't work in the SDK with Python 2.7.
• http://code.google.com/p/googleappengine/issues/detail?id=6267
• Fixed an httplib compatibility issue between Python 2.5 and Python 2.7 in the SDK.
• http://code.google.com/p/googleappengine/issues/detail?id=6271
• Fixed an issue where queries larger than 1MB didn't work with Python 2.7.
• http://code.google.com/p/googleappengine/issues/detail?id=6282
• Fixed an error in the SDK on first page load for a handler.
• http://code.google.com/p/googleappengine/issues/detail?id=6302
• Fixed an issue in the SDK that caused slowness due to app's logs being written to the datastore. Set the --persist_logs flag in the SDK if you are using the Logservice API to read logs.
• http://code.google.com/p/googleappengine/issues/detail?id=6355
• WARNING: Starting with the 1.6.2 release of the experimental Python 2.7 runtime, the mapreduce and datastore_admin builtins will not be supported.

Java Version 1.6.1 - December 13, 2011

Ikai,

Looking at my Application setting, i see that the "Frontend Instance
Class" is set to F2 by default. I didnt change it to F2. However the
docs(http://code.google.com/appengine/docs/adminconsole/
performancesettings.html#Setting_the_Frontend_Instance_Class) say that
F1 is default . Let me know which statement is correct.

[Waleed Abdulla]

A couple of questions:

1. Since not all my requests are the same, I wouldn't want to use bigger front-end instances across the board. Are there plans to allow setting instance type based on app.yaml routes?

2. Can you clarify this point? Will mapreduce not be supported on Python 2.7? 

    "WARNING: Starting with the 1.6.2 release of the experimental Python 2.7 runtime, the mapreduce and

     datastore_admin builtins will not be supported."

Regards,

Waleed

+1 for point 1. But i think to reach there, there was to be some kind
of profiling information that appengine needs to be provide, like /app/
url1 url needs to be run on F4 instances, while /app/url2 needs to run
on F1.

mapreduce will be supported before release (meaning before both Python
2.7 a mapreduce are released non-experimentally)

But it doesn't work in Python 2.7 right now.

Cheers,
Brian

The link to the migration utility seems to have disappeared from application settings?

I can still get to it by going to:

https://appengine.google.com/migrating?&app_id=<APPID>

[pdknsk]

Why do versions have to share frontend classes? It'd be great if this
were app.yaml configurable. I filed a bug for it. Also, how does this
work with discounted instance hours?

Great release! The front-end instance classes makes the change on the pricing a useful thing.

Can someone from AppEngine team acknowledge these questions and answer
them.

star this issue. which allows options available in online admin console to be incorporated in app config file.

Nice work!

I have difficulty to find out any information related to " We've added new functionality to the Log API that will allow you to read your application's logs programmatically."

What does "programmatically" mean here? Any API?
