[google-appengine] checking if datastore key exists for one small operation only

[James Gilliam]

i thought there was a way to see if a database key exists for the price of 
one small operation?

doing keyobj = Key.from_path, followed by filter( '__key__ =', keyobj ), 
followed by query.get() using key only query, you are charged one large and 
one small operation and only get the key returned.

using, get_by_key_name you are charged one large operation, receives the 
entire entity, and it takes longer than the previous.

i have concluded there is no way to check if a key exists for the price of 
a small operation.

does anybody know if there is a way to check whether a key exists for just 
one small operation?

thank you

Re: [google-appengine] reuse existed master/slave datastore app name

[Vinny P]

When you use the migration tool, anyone who visits A.appspot.com will be
redirected to your HRD application at B.appspot.com. You'll need to deploy
your application and index settings to the new application ID, but the
migration tool will automatically move over your datastore entities.

The code you have is sufficient for uploading the XML file. If you want to
parse it, you'll need to import an XML parser, read the data into a DOM,
etc. There are a number of tutorials for this, for example this one:
http://docs.oracle.com/javase/tutorial/jaxp/dom/readingXML.html

For the timeout issue, you can call setConnectTimeout and setReadTimeout on
URLConnection objects to increase the urlfetch timeout.

For the second issue, that's more of a difficult problem; there may be
on-premise firewalls (on your side) blocking the connection. Can you try
opening up a Compute Engine machine and see if you can SSH from there into
your on-premises machines? If not, check the routes and see if the
connection is being dropped anywhere.

It's difficult to state why exactly without any source code, but if I were
you, I'd install AppStats (
https://developers.google.com/appengine/docs/java/tools/appstats ) and
review the datastore calls being made. There may be some calls that you can
prune out.

When you say "off of a database", does this database already exist, or are
you creating a new one? If this database already exists, is it stored on
Google servers, such as Cloud SQL, Cloud Datastore, or a Compute Engine
machine?

Occasionally these errors occur; there's no need to worry about them as
long as they're rarely occurring. Usually they're due to transient issues
within the mail infrastructure.

If you want to try a different approach, use the SendGrid integration to
send your emails:
http://googlecloudplatform.blogspot.com/2013/07/sendgrid-gives-app-engine-developers.html.
You may find it a bit easier to resolve errors.

Hi Gerardo,

I see you sent this email almost 9 days ago, are you still experiencing

If you are, can you try logging out of all Google accounts, then logging

Not directly via App Engine, but you could always use the Apps Scripts

[google-appengine] Re: question on performance and storing non-indexed data in the datastore

[Chad Vincent]

You didn't say which language you're using, but if you're on Java, I 
strongly suggest Objectify.

It defaults all columns/fields to unindexed unless you decorate the field 
with an @Index annotation.

If this is a regression from Java 7, you could always request whitelisting
of your Java 6 app using this form: http://goo.gl/ycffXq

If you don't want to do that, then the best way would be to look at the URL
paths and see if there's a way to consolidate multiple URL path entries
into fewer entries: for an example, see this SO post:
http://stackoverflow.com/questions/11298401/google-app-engine-100-urlmap-entries-limitation

If you can't do any consolidation, you can configure a ServletFilter class
to interpret incoming requests and hand them off to the appropriate
servlets. This should be avoided if possible though, since it can add
additional latency to requests.

As Chad noted, it depends on your runtime and whether you're using the low
level API or some sort of abstraction layer. If you're using the low level
API, there's a way to set certain properties as unindexed (you don't need
to do any conversion). This way is probably the easiest and fastest way.

You can also convert to JSON or XML, but that involves a lot more work
(writing a conversion script, testing, etc). It's much more straightforward
to simply set the columns as unindexed.

Hi,

I see you posted this message quite a few days ago; are you still
encountering issues with this?

If so, can you make a HTTPS request to any other site (NOT myexamplesite.com)
from your App Engine application and if so, does it succeed?

Re: [google-appengine] Re: urlfetch DeadlineExceededError

Hi Stanislau,

There are some services that rate limit requests from hosted platforms
(Google Cloud, AWS, Azure, etc). I don't know if longurl.org does this, but
it wouldn't surprise me.

It looks like longurl is a service to expand URLs; if you need this
functionality, what you could do is a workaround: urlfetch to the "short"
url, follow any redirects, and return the last URL you come to.

the original App Engine console at appspot.com and see if the applications
are listed as deleted there? If not, can you try deleting again?

If you absolutely must get the application down, you can file an issue
here:
https://code.google.com/p/googleappengine/issues/entry?template=Production%20issue

But before you do that, consider this: there's no particular reason to shut
the site down. This looks like a simple proxy, it doesn't look particularly
dangerous or annoying. And you might find yourself wanting to look back on
the work your 13-year-old self did :-)

This sounds like a problem with your local machine: if you look into the
source code of the launcher at
http://google-appengine-wx-launcher.googlecode.com/svn-history/r2/trunk/launcher/addnew_controller.pyit
looks like this message only pops up if a generic OS error occurs.

Can you try logging into your PC's admin account and trying again?

Re: [google-appengine] Google App Engine / Cloud Storage Uploads for php broken in 1.9.0?

Hi David - this is a known issue, we expect to get it addressed ASAP.
https://code.google.com/p/googleappengine/issues/detail?id=10634

And you're quite right - a bug like this should never make it to
production.

Right now we're auditing exactly how an issue like was able to be shipped,
and updating our pre-release testing framework includes checks for
regressions like this.

Re: [google-appengine] default bucket name in GCS

[Amy Unruh]

There is indeed a default auto-created bucket, with bucket name "
your-app.appspot.com", that is getting rolled out and backfilled to
existing apps and their associated projects.  Not all projects may have it
yet.  If the 5GB quota is sufficient for your needs, you ought to be able
to just start using it as you would any bucket.

Go to the Application Settings page for the app engine app you want to use
that bucket with, and grab the app's service account address.
Then go to the cloud console (cloud.google.com/console) and make sure that
service account is listed in the Permissions page of the project that
includes this default bucket, with 'edit' permissions.

I'm unclear on why you need to use Android Studio. Yes, Studio is good for
writing Android apps, but you can also generate Endpoint libraries from
within Eclipse, as well as write mobile apps.

The default bucket should exist for most (but not all) applications,
provided that the App Engine ID is integrated into a cloud project.

If you'd like to test whether or not there's a default bucket ready to go,
you can use your application's runtime to test for the name of the bucket:
Go has DefaultBucketName (
https://godoc.org/code.google.com/p/appengine-go/appengine/file ), Java has
getDefaultGcsBucketName (
https://developers.google.com/appengine/docs/java/javadoc/com/google/appengine/api/appidentity/AppIdentityService)
and PHP/Python have equivalents in the App Identity service.

Hi CK,

Hi Arun,

Most of the time, these types of deployment errors are transient - you
should be able to deploy sooner or later. If this error persists though,
can you try remaking a new App Engine ID and attempt to deploy to it?

I believe this error was fixed a few days ago - it's due to an incorrect

After the *mgr.merge(party)* line, can you test the mgr object to see if it

The deployment was successful, but the application itself is running into
an error (not related to the deployment). Can you check the App Engine
application logs and see if any errors are recorded there? If so, can you
post the error text here?

There's no way to do this. SACSID cookies are only sent over a secure
connection - they won't be supplied over the unsecure HTTP connection. And
you can't clone the SACSID cookie into ACSID.

The best fix would be to keep your entire website as HTTPS, and force HTTPS
if the current browser is using HTTP
