Hi,

Also think about Google Web Toolkit for the UI: you will remain so
full-Java and you can do nice interface even if you are as bad as I am
in graphics / ui design ;-)

I agree with Simon: definitely forget JPA/JDO!  (I went with
Objectify)

Also study carefully the datastore, especially entity groups and
transactions: you will for sure face issues at some point because of
the coupling of the 2 notions. So, try to understand them at best at
the very beginning.

 get my backend working nicely before I think about that.

Forgot:

-about the docs: use the api based on File class for your files in the
blobstore. Just announced yesterday.

- Also, have a look to tasks: that's the way to generate parallelism
in your application if you want to do stuff simultaneously (quick
handling of big data, etc...)

Good luck for your app!

[appengine-java] JPA/JDO vs low level API

2011-04-01 Thread SkYlEsS

I have a question :

What are the differences between JPA/JDO and low level API (and
Objectify) in practice ? I read everywhere the low level API provides
more flexibility, but there are never samples code or evidences to
demonstrate it. So I'm wondering in which cases exactly, the low level
API is useful ?

Thanks in advance

 1. Youtube Direct API. I have two problems here - the user who is

 Also, the videos will be public and become a part of youtube; the
 advantage is its free of cost and will incur GAE charges.

 2. Using blobstore API . Can anyone point me to an example where this
 has been done? What is the best free video player to use?

 I have a small other problem. I am using a restlet framework to create
 REST API's to expose various services. Can i combine Blobstore API
 into restlet framework.

 Any help will be appreciated.

[appengine-java] Small OAuth contribution and a few questions

2011-04-01 Thread Kafkaah

Howdy,

I'm brand new to GAE/Java dev, and wish to ask a few questions about a
simple test code fragment I just deployed.  This (very simple) code
fragment might help someone implement OAuth when integrating GAE with
Google App Script.  I've seen parts of it in a few places, but never
in a complete example.  I needed a way to authenticate a Google Docs
user with my application to restrict access.

The code on the Google App Script side of things:

/***/
function authentication() {
  var oAuthConfig = UrlFetchApp.addOAuthService(google), utc = (new
Date()).toUTCString();
  oAuthConfig.setAccessTokenUrl(https://APP-ID.appspot.com/_ah/
OAuthGetAccessToken);
  oAuthConfig.setRequestTokenUrl(https://APP-ID.appspot.com/_ah/
OAuthGetRequestToken);
  oAuthConfig.setConsumerKey('anonymous');
  oAuthConfig.setConsumerSecret('anonymous');
  var requestData = {
method: GET,
oAuthServiceName: google,
oAuthUseToken: always
  };

  var response = UrlFetchApp.fetch('http://APP-ID.appspot.com/THE-
URI', requestData).getContentText();
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheets()[0];
  var lastRow = sheet.getLastRow();
  sheet.getRange(lastRow + 1, 1).setValue(utc);
  sheet.getRange(lastRow + 1, 2).setValue(response);
}
/***/


On GAE:

/***/
package mypackage;
import java.io.IOException;
import java.util.Date;

import javax.servlet.http.*;
import com.google.appengine.api.users.User;
import com.google.appengine.api.oauth.OAuthService;
import com.google.appengine.api.oauth.OAuthServiceFactory;

public class AppScriptServerServlet extends HttpServlet {
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws IOException {
User user = null;
Date date = new Date(System.currentTimeMillis());
try {
OAuthService oauth =
OAuthServiceFactory.getOAuthService();
user = oauth.getCurrentUser();
resp.getWriter().println(Request time:  +
date.toString() +  User:  + user.getNickname());
} catch (Exception e) {
resp.getWriter().println(Request time:  + date.toString() +
 Exception:  + e.toString());
}
}
}
/***/


My 2 questions:

1. I have set up a time driven trigger on GAS to execute the script
every minute.  It seems I get current Date values from the GAE app
every 6 minutes +-6 seconds (very monotonously):

Fri, 01 Apr 2011 20:05:12 GMT   ::   Request time: Fri Apr 01
20:01:14 UTC 2011 User: u...@domain.com
Fri, 01 Apr 2011 20:06:12 GMT   ::   Request time: Fri Apr 01
20:01:14 UTC 2011 User: u...@domain.com
Fri, 01 Apr 2011 20:07:12 GMT   ::   Request time: Fri Apr 01
20:07:14 UTC 2011 User: u...@domain.com
Fri, 01 Apr 2011 20:08:12 GMT   ::   Request time: Fri Apr 01
20:07:14 UTC 2011 User: u...@domain.com
  .
  .
  .
Fri, 01 Apr 2011 20:11:12 GMT   ::   Request time: Fri Apr 01
20:07:14 UTC 2011 User: u...@domain.com
Fri, 01 Apr 2011 20:12:12 GMT   ::   Request time: Fri Apr 01
20:07:14 UTC 2011 User: u...@domain.com
Fri, 01 Apr 2011 20:13:12 GMT   ::   Request time: Fri Apr 01
20:13:15 UTC 2011 User: u...@domain.com
Fri, 01 Apr 2011 20:14:12 GMT   ::   Request time: Fri Apr 01
20:13:15 UTC 2011 User: u...@domain.com

What am I doing wrong? (if it's Java related, very sorry, my last Java
classes date back more than 6 minutes ago);

2. This very simple app generates a lot of CPU time.  From the GAE
Dashboard:
/MY-URI   ::   36 [requests]  ::   1741 (0) [Avg CPU
(API)]  ::   100% [% CPU]

The Quota Details page is more reassuring: my immediate CPU Quota is
Okay.

Am I right to think this is a discrepancy?  Aren't both of these
values a short-time average (over a minute)?  I guess I'll trust the
value I like best: Okay

Thanks

Re: [appengine-java] Uploading New Data into App Engine Java App

It sounds like you'll want to build your own API for this. Once you invoke
the API, all it has to do is follow up and run whatever code you need to
run.

One of the team members released Protorpc to help facilitate this sort of
thing in Python to make it easier to communicate between client and server
code. It's his goal to implement the same thing in Java. Check it out:

Re: [appengine-java] Re: Tips/Pitfalls for total newbies?

I think we can better surface the projects that are built by App Engine team
members that aren't so obviously accessible from the docs. It's important to
understand what these tools provide. A few off the top of my head:

- App Engine Mapreduce (so far only Map step is implemented but still *very*
useful):
http://code.google.com/p/appengine-mapreduce/

- The pipeline API:
http://code.google.com/p/appengine-pipeline/

- Protorpc
http://code.google.com/p/google-protorpc/

Am I forgetting any?

I'm sure community members can also recommend great third party tools you
can use. Some of these third party tools even have their own very active
sub-communites!

The simplest way is to write a servlet on GAE.

When your own server is done with the calculation, it posts (http
POST) the new data to this servlet who reads it and separate each line
as a new entity in the datastore.

The servlet can then do further processing (cleanup, updates, etc.) if
needed and launch a queued task (or several in parallel if you need
speed via parallelism) to do all what's remaining.

 Could someone please recommend - what is the best way to:
 1) How to upload this kind of data programmatically into the Java App Engine
 app
 2) How to detect the new data has arrived from inside app engine, and reload
 it from the file - which tools in Java?

 I could not find the uploading data section under the Java part of the

[appengine-java] Re: JPA/JDO vs low level API

Hi,

You should also consider 3rd party packages like Objectify who works
at an intermediate level of abstraction.

The low-level api forces you to handle everything by yourself: the
Entity, its Properties, etc...

In JPA, JDO: you work much higher in abstraction: you define a Java
class as an Entity and then its properties become DS properties as you
annotate them.

As said: the big difference is abstraction level and resulting
guidance for JDO or flexibility for low-level: with low-level, you can
do much more things but you have to program much more carefully and
now what you do. With JDO/JPA, you get more comfort as you are guided
by the pojo structure. Also, JDO/JPA aligns you with Java
(inheritance, compiler checks for types, etc...).

I would really advise to start somewhere in the middle with a 3rd
party package as they are recommended now by Google more than JDO/JPA
and learn by using it at its own middle abstraction layer. When you
understand better, you will see if you really want / need to go up or
down in abstraction or stay where you are.

regards

didier

 frameworks that rely on that particular address space, perhaps more commonly
 referred to as cloud leveraged app platforms.

 The problem is that search engines - such as Google's - are routinely

 as a vector tampering with other, external properties. No amount of
 sanitization can counter the fundamental lack of a permissible URL
 tokenizing framework, i.e. something which communicates in a uniform manner
 to all interested parties (i.e. the Google family) what a permissible URL
 looks like.

 Sadly, the robots.txt syntax and the meta tag nofollow,noindex both lack
 this syntax whitelisting feature; they are not prescriptive (only crawl
 and index the URLs that look like this, and ignore the rest). Of course,
 with many if not most standard on-site search queries, it is possible to
 script page headers that include nofollow,noindex metatags. But many other
 kinds of dynamic content aren't easily wrapped with such headers.

 And that is where abuse of poisoned search engine indexes come into play.

 Just as I can't hunt down every non-canonical URL in the Google index,
 flagging issues case-by-case is not only not effective (if only because my
 logs demonstrate that) but practically prohibitive as well (I assume you can
 imagine that I'm not interested in hunting down all search engine based
 botnet traffic and relating that to individual sources) so my alternative is
 to simply shut down access to search engines. I don't have the time or the
 resources to play whack a mole with the ever increasing scourge of botnets.
 Incidentally, a look at traffic evolution in my traffic logs and a cursory
 look at some well-known email spam statistics suggests that indeed there's a
 quantum shift afoot, shifting from email to (particularly) smaller web
 property targeting for invasive advertising methods by the miscreants out
 there.

 And that is exactly what I have chosen to do: the well-behaved search
 engines (Google, Bing, Yahoo) are informed via robots.txt that they are not
 welcome, and their indexes are cleared out; the ill-behaved ones are blocked
 and upon sight rigorously reported to blacklists.

 Until there is something available which gives website proprietors
 (especially the small to medium sized ones!) a trivial and effective means
 to control which content is accessible for storage and further processing in
 the cloud, the internet will continue to shrink.

 Indeed, with heavy heart. But I don't have the resources to keep my
 web-based property open to play nice with worthwhile endeavors such as
 Google App Engine, while a notorious minority of criminals (I openly prefer
 the terrorist moniker) runs amok with virtual impunity. And so, I set a
 tight regime for wrapper security scripts (e.g. ZB Block, which I find quite
 effective and flexible).

 Hopefully you now understand better; it's not that I mistrust Google, or
 Google App Engine in particular. I just can't afford to be available for
 well-intended fun and games while carrying the weight of incidental abuse at
 my own expense.

Hi all,

Forgive me if there's a better place to ask this question:

I put on a web  mobile competition/showcase called 
59DaysOfCodehttp://59DaysOfCode.com. 
One of the things we are offering this year is a set of workshops for 
developers on various topics. Twilio and Amazon (AWS) among others, will be 
holding sessions.

Is there someone I might speak to in the App Engine community, or within

[google-appengine] Don't Understand Blobstore limits

2011-04-01 Thread Movesax

I'm reading numbers all over the place about blobstore and I don't really
understand their implications. If anyone could help, it would be greatly
appreciated.
from:
http://code.google.com/appengine/docs/python/blobstore/overview.html#Writing_Files_to_the_Blobstore

it says that filesizes in the blobstore are limited to 2GB
but it also says that the maximum amount that can be written with a single
API call is 1mb.

Does that mean that a 2GB file could be uploaded downloaded so long as it
were chunked into 1mb pieces?
Also, I saw that entry was linked from a fairly recent blog post - Is that
the most 'up to date information on Blob limits?' I think I've also seen
that 50mb is their limit.

And what about attaching Blobs to other Data Structures? There's a limit on
the size that data structures can be in the datastore... I'm not sure what
that is currently, but I know that it used to be 1mb. Even if we can have
large blobs, does this mean we can't have them attached to other data
structures?

Also, I saw someone linked to a new Google Storage API. Is this going to
somehow be accessible to the GAE?

Finally, these limitations should probably be mentioned somewhere in the
overview or maybe quota sections. I had a terrible time finding the little
information I found :(

Re: [google-appengine] How to block Google App Engine?

2011-04-01 Thread Ross M Karchner

I think the phrase search engine related API development frameworks
might be the key to the misunderstanding here-- App Engine and Google
Search are simply products of the same company. It's like calling
Microsoft Windows a search related operating system simply because
Microsoft also makes Bing.

App Engine is just a thing for hosting web sites and web apps--
anything you could do on App Engine, you could also do on GoDaddy,
Bluehost, Rackspace, Azure, 11, Webfaction, Dreamhost, Slicehost,
Heroku, Engine Yard, A Small Orange, Amazon EC2, etc.

Things I *would* call search engine related API development frameworks:

- http://www.rollyo.com/
- Google Custom Search (and it's API)
- Yahoo Boss: http://developer.yahoo.com/search/boss/

Re: [google-appengine] Don't Understand Blobstore limits

Hi,
The maximum size of a blob is 2GB. If you are uploading the blob
from your app code, I believe the data will be sent in 1Mb chunks. If
you are reading from a blob in your app code, read the data in 1Mb
chunks. Clients can send up to 2GB if you use the
BlobstoreUploadHandler, and they can also download that data if you
use the BlobstoreDownloadHandler.

You can reference blobs from your Datastore entities:

http://code.google.com/appengine/docs/python/datastore/typesandpropertyclasses.html#BlobReferenceProperty

Google Storage for Developers is on the Roadmap:
http://code.google.com/appengine/docs/roadmap.html

A lot of quota information is in the general quota doc:
http://code.google.com/appengine/docs/quotas.html

Many of the service overview sections, such as the Datstore and
Blobstore, detail relevant quotas:

[google-appengine] PerformanceEngine - This is how I stay under free quota (feedback welcome)

2011-04-01 Thread Can Bascil

Hi there,
I am working on an app (tweethit.com) that has high frequency of write
 read ops and came up with this library as a side project. It
basically enables layered storage for db.Models. You can select which
layers to put or get the models (local cache,memcache,datastore) using
a simple API. It cut my CPU usage by nearly half as soon as I
introduced local layer for storage, so you should check it out if you
like to stay under free quota as much as I do. All feedback is
welcome. I'd love to know how else I can add useful functionality to
this simple library.

[google-appengine] Files API Performance

2011-04-01 Thread Fabs

Hello all

I currently have an app running which stores 16MB binary files by
having a list of keys, and a number of 'data' entities storing the
data. This has good performance with the new async datastore APIs. I
am interested to know if the files API will match the performance of a
number of asynchronous datastore reads, or if the files API will have
additional latency.

I realise the files API is experimental and should not be used in
production yet, but it seems like it will be a more robust solution to
my problem.

Regards.

[google-appengine] Getting one bill a month for the App Engine Usage

2011-04-01 Thread Nixarn

Hi,

We've been using the App Engine for a while now and it works great.
One thing though that would be really great would be to get less
bills, in the beginning we used to get really tiny bills once a week
which was annoying. Another option is to be able to prepay a large
amount.

Thanks,
Niklas

Re: [google-appengine] Files API Performance

2011-04-01 Thread Ian Gillett

I am using the resumable upload function to Google Docs in App Engine.


I thought I would be able to use the new Files API to accomplish this.


My question is how can I use the new Files API to grab a reference to a blob
and cast to file in the following code snippet:


MediaFileSource mediaFile = *new* MediaFileSource(file, contentType);


The problem is the resumable upload expects a regular file type when
creating a MediaFileSource and obviously App Engine does not allow reading
from the users file system – will the new Files Api help with this?


Any help hugely appreciated...


Thanks,

Ian.

We have a pilot project that gets charged 7c a week... It drives the
accountant crazy. I find it amusing that Google (as in Google App
Engine) charges our credit card 7c every Monday but Google (as in
Google ads) will not send us a check until the amount reaches $10.00
because of overhead reasons...

I suggest GAE charges as often as once a day when the balance exceeds
$100.00 but  once a month if the amount is below that, or something
along these lines so we only get many accounting entries if the amount
justifies the overhead.

[google-appengine] Re: How to filter date

2011-04-01 Thread nickmilon

you need something like:

News.all().filter('created_at.month ',datetime(2011,3,31,23,59))

but..

your result set will be ordered primarily on created_at coz you are
using an inequality filter, if you do not mind that then ok.

IMHO a better solution to your problem would be if you use an equality
filter based on a computed property:

class BaseArticleModel(polymodel.PolyModel):
title = db.StringProperty()
created_at = db.DateProperty(auto_now_add=True)
updated_at = db.DateProperty(auto_now=True)
@db.ComputedProperty
def CM(self):return self.created_at.month

then you can filter on an equality which is much more convenient for
the query at the expense of a little overhead on storage and put
latency:

q = News.all().filter('CM =',1)


happy coding;)

I am currently using Id's instead of keys for references.
(as I would not make use of the back references)

[google-appengine] Re: Best API to use for storing fairly small files

2011-04-01 Thread Jordon Wii

@Calvin: Good point, I'd forgotten about that.  The file-concatenation
also an interesting idea, although I'm not sure exactly how I would
implement that.

@Robert: Thanks a million for those links.  They're looking quite
helpful.

 Datastore entities are capped at 1 megabyte.  So if you expect anyone to
 ever upload a file larger than that, blobstore would be required.  Also the
 uploading might be faster if you could join all the files into a single
 compressed file on the client and upload them all at once.  Blobstore would
 be good for that.

[google-appengine] Re: NeedIndexError ? Please help

2011-04-01 Thread PandaSuit

You are going to have lots of trouble with any index that contains the
same property more than once. Based on your index I am guessing you
are implementing search with a list property called
__searchable_text_index that contains a bunch of search terms are you
are doing an equality filter against that property. If I am wrong just
feel free to ignore the rest of this post.

On the dev server this will work fine no matter how many equality
filters you use in a single query however on the production server it
will require an index for each number of equality filters and the
production server will fail to create those indexes because it does
not seem to support an index with more than one entry for the same
property.

This is a little tricky. If you want to filter with multiple equality
filters on the same property like that you are not able to filter on
any other property or sort on any other property in the same query.

Multiple solutions for this have been found but none are perfect. The
search solution that I use is gae-search by Bill Katz:
http://www.billkatz.com/2009/6/Simple-Full-Text-Search-for-App-Engine

You still won't be able to have the sort inside the same query as the
filter, you will need to sort after you have fetched the results.

I hope that helps. Good luck.

[google-appengine] Migrating from MS to HR

2011-04-01 Thread Greg

I have a production appengine app at www.example.com, which I want to
switch from master-slave to high replication datastore. I intend to
document and publish the process and the results to make switching
easier for others who want to make the move.

The cut-over must be as seamless as possible. I can set up the HR app
and transfer most of the data across ahead of time using the appspot
URL, followed by testing the new app to make sure everything works as
expected. Then there will have to be a small downtime window while I
disable the old app and transfer the remaining data.

My questions (so far!) are:

1. What is the process for switching old to new app in google apps?
Currently in my example.com google apps dashboard I have a link to
disable the old app. When I do this, will I will get the option to
associate the new app with the domain?

2. How quick can this app switch happen? Is there any manual component
on Google's end that would require me to do this in office hours?

[google-appengine] Re: Redirect from naked domain preserving full path

2011-04-01 Thread Thomas Wiradikusuma

Hi Giacinto,

I'm having exactly the same problem. Can you get into more detail
(step-by-step, starting from 
https://www.google.com/a/cpanel/MYDOMAIN/DomainSettingsDomains
probably?) on how you get it done? I understand your post, but I'm
afraid I might click/delete the wrong stuff.

 Well, i solved the problem! None of the previous solutions is really the
 good solution, or better, none is complete. The real problem of the lost
 request's full path is the google autosetting for www redirect!

Re: [google-appengine] Please help

Yeah - take a look at creating Django template filters. These are much
easier to use in newer versions of Django than the default (0.96):
