[google-appengine] Re: GAE getting CAPTCHA-locked by Google Apps?

[Lucas]

I don't know if you've resolved this issue or not, but I think I've
found a way around the problem.
Try using the datastore to save the auth string for future use.  If
the auth string stops working, have your application run reAuth().
Replace all occurrences of SERVICE with the Google service for which
you're using ClientLogin.
I haven't tested the code, but it goes a little something like this:

import urllib, urllib2, re
from google.appengine.ext import db

class Auth(db.Model):
  authtype = db.StringProperty()
  content = db.StringProperty()

def reAuth():
  auth_req_data =
urllib.urlencode({'accountType':'GOOGLE','Email':GOOGLE_ACCOUNT,'Passwd':GOOGLE_PASSWORD,'service':SERVICE,'source':YOUR_APP_NAME})
  auth_req_url = 'https://www.google.com/accounts/ClientLogin'
  auth_req = urllib2.Request(auth_req_url, auth_req_data)
  try: response = urllib2.urlopen(auth_req)
  except urllib2.URLError, e:
print e
exit(e)
  result = re.findall('Auth=([-_A-z0-9]+)', response)
  if result: result=result[0]
  newAuth = Auth()
  newAuth.authtype = 'SERVICE'
  newAuth.content = result
  newAuth.put()
  return result

data = db.GqlQuery("SELECT * FROM Auth WHERE authtype =
'SERVICE'").get()
if data:  auth = data.content  #Use existing authstring
else:  auth = reAuth()  #Use new authstring

[google-appengine] New GAE/J app fails to start - FATAL ERROR in native method: processing of -javaagent failed

[vogella]

Hi,

I create a new GAE/J app via the Eclipse Plugin. Directly after

Previously I was able to create GAE/J. Mz Java version is Java(TM) SE

Any advice?

[google-appengine] claiming unavailable appspot subdomain

[Vez]

I am currently the owner of mixnote.com. For my app, I require a
subdomain for each user. I see that Google App Engine does not
currently support subdomains for custom domains, so I would at least
like to use mixnote.appspot.com. (I had to take "mixnotecom" instead.)
Unfortunately, this is listed as unavailable from the "Create an
Application" page. I also see that there is no public app currently
running there. Is there any possibility that I could get this address?
If someone else has chosen the "mixnote" app identifier, I would like
to contact them and ask for it.

md5 isn't deprecated in python 2.6 because it's been hacked; hashlib
consolidates the scattered hashing modules into 1.  It still lets you
use md5.

also:
[~] % python
Python 2.5.4 (r254:67916, Jul  7 2009, 23:51:24)
[GCC 4.2.1 (Apple Inc. build 5646)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import md5
>>> ^D
[~] % python2.6
Python 2.6.2 (r262:71600, Jul 17 2009, 11:51:35)
[GCC 4.0.1 (Apple Inc. build 5465)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import md5
__main__:1: DeprecationWarning: the md5 module is deprecated; use
hashlib instead
>>>

YMMV.

[google-appengine] Re: Use Of Deprecated Code

[Tim Hoffman]

I am running 2.5.4 on 9.10 and don't get the deprecation warning and
never have with appengine and I have.

As for MD5 being hacked, yep but the ramifications of that are
dependent on why it is being used.
If you are using it to generate hashes to compare files that only you
have access too then I would suggest there is little or no risk.
So that isn't exactly sweeping things under the rug.

And as for 2.6.4 yes it runsappengine fine in dev, and your code base
will work
in prod right up until you start using any code with the "with"
statement for instance.

There are more than a few postings in this group where people cant get
things to work
purely because they have been using 2.6.x

[google-appengine] Re: Use Of Deprecated Code

[JoeM]

I checked and saw that since I upgraded to Ubuntu 9.10 the Python has
been changed to Python 2.6.4.  However your theory about lack of
Python
2.5 being the cause of the deprecation messages is refuted by the fact
that when
I ran with Python 2.5.4 I got the same deprecation warnings for md5
only much more of them.
I fixed my 2.5.4 as advised and they went away.

In any event now that it is known that md5 has been hacked it should
be fixed not swept
under any rug.

Just an FYI Google appengine runs fine with Python 2.6.4.

[google-appengine] Prerelease: New Appengine Bulkloader

[Matthew Blain]

I’d like to announce a wider prerelease of the new App Engine
Bulkloader configuration format. This new format extends the existing
bulkloader with a new format with several advantages:

  * Semi-Automatic configuration generation: The SDK can generate a
bulkloader configuration based on your existing data.
  * Supports more data formats. CSV support has been extended to files
with headers, basic XML support has been added, and it is simpler to
use alternate text encodings in the files. Additional and custom data
connectors are now easier to create.
  * Easier to use -- the new syntax is more declarative and
descriptive than the old one. Developers who use languages other than
Python no longer need to write code in the Python language, although
the Python SDK is still required to run the tool.

To try out the new bulkloader, please visit http://bulkloadersample.appspot.com/
. Preliminary documentation is available on the README on that site
along with a version of the 1.3.2 Python SDK containing the new
bulkloader.

You can send feedback to the group or directly to me.

Re: [google-appengine] Re: Accessing Amazon SimpleDB from Google App Engine

[Ikai L (Google)]

The reason this code isn't working is because it's build on top of Apache
Commons HttpClient. You'll need to use URL and URLConnection to make your
REST calls instead.

This is definitely possible, as people have created a Python library for
doing this:

http://code.google.com/p/appengine-simpledb/source/browse/#svn/trunk

You're using Java. I haven't seen anything in my searches for examples
making SimpleDB calls in Java (probably because developers just use App
Engine's datastore for persistence). You'll likely have to roll your own
client against the REST spec:

[google-appengine] Re: Accessing Amazon SimpleDB from Google App Engine

[deuce4]

I tried with this
//below gives error: java.lang.NoClassDefFoundError: org/apache/
commons/httpclient/HttpMethod

//AmazonSimpleDB sdb = new AmazonSimpleDBClient(new
PropertiesCredentials(
//
ClockServlet.class.getResourceAsStream("AwsCredentials.properties")));
//
//
System.out.println("===");
//System.out.println("Getting Started with Amazon SimpleDB");
//
System.out.println("===\n");
//
//
//// Create a domain
//String myDomain = "MyStore";
//System.out.println("Creating domain called " + myDomain
+ ".\n");
//sdb.createDomain(new CreateDomainRequest(myDomain));
//
//// List domains
//System.out.println("Listing all domains in your account:
\n");
//for (String domainName :
sdb.listDomains().getDomainNames()) {
//System.out.println("  " + domainName);
//}
//System.out.println();

I don't have the URL fetch code attempt anymore--mostly I have the
fundamental question of how to create a custom connection object like
the sdb above into a Google App Engine URL Fetch connection object.

I'm a novice with Google App Engine

Any specific help would be super appreciated in connecting a Amazon
SImpleDB to a Java Servlet in Google App Engine.

thanks

[google-appengine] Downloading Primary Keys with appcfg.py

[Benjamin]

I'm downloading data from my production data store into a CSV using
appcfg.py and the remote_API  everything works great but i can't seem
to download the identity column. All of my persisteny properties come
down just fine. The property marked with :

@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
public Long id;

isn't accessible.  I'm assuming i just don't know how to create the
model correctly since i'm new to python.  I'm getting a
MissingPropertyError: ID message

I'm thinking it's somthing simple regarding how i'm setting the id
= ..   in both my exporter and model
Here is my model:

class NimbitsUser(db.Model):
id = db.IntegerProperty()   < wrong eh?
email = db.StringProperty()
user = db.StringProperty()
userkey = db.StringProperty()
dateCreated = db.DateProperty()

and my exporter:

class UserExporter(bulkloader.Exporter):
def __init__(self):
bulkloader.Exporter.__init__(self, 'NimbitsUser',
 [('email', str, None),
  ('user', str, None),
  ('userkey', str, None),
  ('dateCreated', str, None),
   ('id', int, None)
 ])

Re: [google-appengine] Mark as default a deployed version programmatically

[Nick Johnson (Google)]

Hi Pedro,

Currently the only way to switch default versions is via the admin console.
If you're using a continuous build process, the easiest way to make sure
it's the default version is to use the same version name consistently.

mydomain.com  (payment)  - and then use googleapps to manage
their business.

[google-appengine] Re: Task Queue implementation details

[peterk]

A question re. 'stable storage'...

...is it possible that might be opened up in a more general way in the
future? Even with limitations on how much an app can store at a time
or whatnot?

Memcache is nice, but the unpredictability of it makes it a no-no for
me in some cases.

But if there was some kind of temporary stable storage that was as
fast to write to as it is to add a task to the queue, that could be a
nice layer in between datastore and memcache.

Sorry to go off topic...

Re: [google-appengine] How to do Reversed Ajax Call crossing user on GAE

[Ulrich]

g3 insight wrote:

We are facing one problem when implementing reversed ajax call
crossing users on GAE
It is a game center, many client users join the game and play
together.
We supposed that there is a singleton Game Center instance, and all
user is saved in user list within this Game Center instance.
Then, if UserA did one request in game, and want to ask whether UserB
accept it, then system(server side) will do one reverse ajax call to
UserB to ask his response when processing UserA's request.
Also, when there is any data update on user or game, we will also use
reverse ajax call to push those new data to each client user in
UserList which is saved in Game Center instance.
Now, we understood the Game Center class will be initialized in
different server (JVM), so Game Center is not singleton instance on
GAE.
Also we found that it is very difficult to do reverse ajax call
crossing users on GAE, because we can not do reverse ajax call to
client UserY who is on serverB, when system is processing request of
UserX on serverA.
Any idea for handling this type Reverse Ajax Solution (Comet) on GAE?

  
Afaik, push notifications / Comet is currently not supported and using 
things like long polling is not possible, too. But you could possibly 
use the XMPP service 
() for push 
notifications.

[google-appengine] Re: Singleton class become double instance in GAE

[Tim Hoffman]

Hi

Probably your only possibility will be for the Game Center instance to
hold the current state in memcache, so that all
instances of the Game Center see the same state.  Load the state on
each request. Remember each running  instance is single threaded.

Your main problem will be to stop multiple requests overwriting state
in memcache hopefully your data structure may not mean this happens.
Also I would consider a task that is constantly copying the memcache
state to the datastore so that if
the memcache data is lost you can recreate it from a recent copy in
the datastore.

[google-appengine] How to do Reversed Ajax Call crossing user on GAE

[g3 insight]

We are facing one problem when implementing reversed ajax call
crossing users on GAE
It is a game center, many client users join the game and play
together.
We supposed that there is a singleton Game Center instance, and all
user is saved in user list within this Game Center instance.
Then, if UserA did one request in game, and want to ask whether UserB
accept it, then system(server side) will do one reverse ajax call to
UserB to ask his response when processing UserA's request.
Also, when there is any data update on user or game, we will also use
reverse ajax call to push those new data to each client user in
UserList which is saved in Game Center instance.
Now, we understood the Game Center class will be initialized in
different server (JVM), so Game Center is not singleton instance on
GAE.
Also we found that it is very difficult to do reverse ajax call
crossing users on GAE, because we can not do reverse ajax call to
client UserY who is on serverB, when system is processing request of
UserX on serverA.
Any idea for handling this type Reverse Ajax Solution (Comet) on GAE?

[google-appengine] Re: Singleton class become double instance in GAE

[g3 insight]

Yes, it is causing problem for our solution.
Let me explain our solution on GAE.

It is a game center, many client users join the game and play
together.
We supposed that there is a singleton Game Center instance, and all
user is saved in user list within this Game Center instance.
Then, if UserA did one request in game, and want to ask whether UserB
accept it, then system(server side) will do one reverse ajax call to
UserB to ask his response when processing UserA's request.
Also, when there is any data update on user or game, we will also use
reverse ajax call to push those new data to each client user in
UserList which is saved in Game Center instance.

Now, we understood the Game Center class will be initialized in each
server (JVM), so Game Center is not singleton instance on GAE.
Also we found that it is becoming difficult to do reverse ajax call
crossing users on GAE, because we can not do reverse ajax call to
client UserY who is on serverB, when system is processing request of
UserX on serverA.

Any idea for handling this type Reverse Ajax Solution (Comet) on GAE?

Re: [google-appengine] Am I allowed to do this?

Hi Spines,

This is a legitimate use of multiple apps - though I would strongly suggest
simply structurally separating your code inside a single app - it'll be much
simpler, faster, and probably cleaner.

All tasks have an ETA - the default is just 'now'. Named tasks have special

being enqueued.

No. Our task queue depends on a large amount of internal infrastructure, and
