1.6.2 Pre-Release SDKs Out

[Marzia Niccolai]

Hi,

The 1.6.2 were uploaded yesterday. Release notes are below.

- Marzia

Java Version 1.6.2
===================- The Admin Console Datastore Admin has added experimental backup and restore
  functionality. The job occurs within your application and counts against your
  application quota, including Instance Hours, Datastore Ops and Datastore
  Storage.
- Channel API quota is now automatically measured in terms of minutes a channel
  has been open, instead of channels created. Additionally, developers can now
  specify how long a channel can be open, with the default remaining two hours.
- Task Queue API requests now include a X-Appengine-TaskETA header, that can be
  used to measure task delivery latency.
- We have removed the deprecated labs version of the TaskQueue API.
- The default API deadlines for Blobstore API calls have been raised to 15s for
  online and 30s for offline requests, up from 5s.
- The Images API now allows you to stretch an image without maintaining the
  aspect ratio.
    http://code.google.com/p/googleappengine/issues/detail?id=2220
- Fixed an issue where the SDK did not resize images down to 512 pixels by
  default, as it does in production.
- Fixed an issue with the Images API where valid images were returning a
  NotImageError.

  of the results.

  2.7.

  2.7.
    http://code.google.com/p/googleappengine/issues/detail?id=6265
- Fixed an issue with the sql datastore stub in Python 2.7 where the sqlite
  module no longer accepted strings with non-ASCII characters.
    http://code.google.com/p/googleappengine/issues/detail?id=6290

  an Entity which defines an index with no properties.
    http://code.google.com/p/googleappengine/issues/detail?id=6600
- Fixed an issue where transactional tasks were not enqueued in the SDK when
  running in high_replication mode.

  has been open, instead of channels created. Additionally, developers can now

This is a welcome change. How is the pricing set? Is it:

$0.00005 / hour (( $0.01 / (100 * 120)) * 60)

12,000 minutes free ( 100 channels * 120 minutes )

Thanks

[Robert Kluin]

Look like some good changes / improvements are coming.

Thanks to the task queue team for the help recently, and for adding
TaskETA header for debugging some things.

Plus probably 15 minute fee per channel opening :(

[Prateek Malhotra]

Not updating to the latest NDB? I know its experimental but it got
some pertinent bug fixes and optimization since the last SDK release.

[Prateek Malhotra]

Strike that, I was looking in the wrong place. On a side note, will
google.appengine.ext.ndb.utils.DEBUG be set to True or False in
production?

It would be super cool if the backup feature allows me to backup my data to Google's Cloud SQL so it's a backup and, as the same time, a good place to run reports that require the complex queries that SQL is good at.

[Timofey Koolin]

I want function for keep or close channel by server side.

For example I open channel for 48 hours. If user have active during it period - I prolong channel for next 48 hours. It need for incremental update client state for web-application.

Is it advisable to use the pre-release version in production or are
people just experimenting it on dev?

When will it be available here - http://code.google.com/appengine/downloads.html?

It will stay True. However feel free to set it to False in your app
after you've debugged it (your app, that is :-). This will reduce the
amount of work done to save debug info in every Future.

PS. A better place to ask questions about NDB is appengine-ndb-
discuss.
