Hi again,
1. *dev_appserver*: I replied in my other email that the tool currently
is available for Python 3 but still requires some components from 2.7 to
function properly and suggested you can file an external bug to make it
fully functional in 3.x.
2. *bundled services*: Google has made available as many of the bundled
services as possible, but unfortunately there's currently no plan on making
search available in the next generation runtimes. It is currently
recommended to migrate to Elastic Search using a Compute Engine VM
<https://cloudplatform.googleblog.com/2015/01/Deploy-Elasticsearch-on-Google-Compute-Engine.html>
as
recommended here
<https://cloud.google.com/appengine/docs/standard/python/migrate-to-python3/migrating-services#search>.
The goal is not "to move people away from App Engine," but to make
developers' apps more portable, so they can take their apps elsewhere if
App Engine isn't the right fit for their needs (removing the notion of
"vendor lock-in") by encouraging developers to migrate away from those
legacy bundled services. They are strickly a migration tool to ease
upgrading to Python 3 and will not receive any new features... all of the
innovation is going into any standalone Cloud equivalent services.
3. *2.x support*: As Alejandro alluded to, there are no current plans to
shutdown the Python 2 runtime, even with the sunset of Python 2
<http://python.org/doc/sunset-python-2/>, older Java, PHP 5, and Go
versions older than 1.11, by their respective communities. Google Cloud has
assured users by expressing continued long-term support of these legacy
runtimes
<https://cloud.google.com/appengine/docs/standard/long-term-support>,
including maintaining the Python 2 runtime
<https://cloud.google.com/python/docs/python2-sunset>. So while there is
no requirement for users to migrate to Python 3 at this time, developers
like you are expressing interest in updating their applications to the
latest language releases.
Best regards,
--Wesley
