[google-appengine] Re: "This application ID or version is already in use." Why?

[K_Reverter]

I hope to use "dituren.appspot.com" as my app id very much.Because I
already registered "dituren-mapplet.appspot.com","dituren-
service.appspot.com" and "dituren-www.appspot.com".

Also I'm the owner of domain "dituren.cn" and "dituren.com".

I tried send mail to "ditu...@gmail.com" and "d1tu...@gmail.com" and
the Gmail server return a error.

So I think I can use this appid,

Can you tell me why "dituren" was reserved?

[google-appengine] Re: ImportError: No module named twitter

[Kajikawa Jeremy]

are you installing the module into the local python library of modules
  for local use?

My understanding is original sources for modules not in the GAE stdlib
  need to be included with the project itself to make them work.

if the module is named "mymod" then it will need to be
  in "projectpath"/"mymod" ...

I hope this is clear for you.

[google-appengine] Re: Parallel urlfetch utility class / function.

[Joe Bowman]

This may be a really dumb question, but.. I'm still learning so...

Is there a way to do something other than a direct api call
asynchronously? I'm writing a script that pulls from multiple sources,
sometimes with higher level calls that use urlfetch, such as gdata.
Since I'm attempting to pull from multiple sources, and sometimes
multiple urls from each source, I'm trying to figure out if it's
possible to run other methods at the same time.

For example, I want to pull a youtube entry for several different
authors. The youtube api doesn't allow multiple authors in a request
(I have a enhancement request in for that though), so I need to do a
yt_service.GetYouTubeVideoFeed() for each author, then splice them
together into one feed. As I'm also working with Boss, and eventually
Twitter, I'll have feeds to pull from those sources as well.

My current application layout is using appengine-patch to provide
django. I've set up a Boss and Youtube "model" with get methods that
handle getting the data. So I can do something similar to:

web_results = models.Boss.get(request.GET['term'], start=start)
news_results = models.Boss.get(request.GET['term'], vertical="news",
start=start)
youtube = models.Youtube.get(request.GET['term'], start=start)

Ideally, I'd like some of those models to be able to do asynchronous
tasks within their get function, and then also, I'd like to run the
above requests at the same, which should really speed the request up.

Hi Marzia!

Thank you for replying...

I tried it again, and it didn't work for a while... And then suddenly
it started working... I have completely no idea what went on...

Anyway, thank you!

[google-appengine] Re: Lost source code --help retrieving

[Sargis Dallakyan]

I came across this nice app recently:
http://enter.appspot.com

I would try the following, if I was in your place:
Register another app with the same account and upload this app and
maybe this one for debugging:
http://con.appspot.com

Your app engine files are located at "/base/data/home/apps/"+app_id
+"/"+version_id. You can find your
app_id and version_id by logging into App Engine and checking your
Dashboard url:

See if you can list your app egine directory from another app, you
created, and let us know if you succeed.

[google-appengine] Re: ImportError: No module named twitter

[Tim Bull]

Tad obvious perhaps but in the interest of offering some assistance,
remember if it's not a standard GAE module, you have to include the
python lib into the directory of the application.

So if you're application is called "twitterbot" for example, you
should have a directory under this directory called twitter (e.g.
\twitterbot\twitter) and the library files for the twitter python lib
should be in the twitter directory.

On a seperate note, from what I've read, I don't believe that the
twitter python lib works natively with GAE and needs some modification
because it uses a C optimised JSON library which is not supported in
GAE -- I could be wrong on this, just a heads up, you might want to
check this out if you have issues.

As a further note, if you're developing any kind of "serious" twitter
app, search the code forums here, there are a lot of complaints about
Twitter API limits being reached because of the number of Twitter Apps
calling from GAE -- Twitter can't distinguish between them so they are
hitting API limits very regularly.

Cheers,

Tim

Hi,

The latency has been resolved, I believe Pete's email meant the following
line 'During the week of March 2nd' to indicate the duration of the
downtime.  In the future we will make sure that the language is more clear
when expressing the timeframe when any issue occurred.

[google-appengine] Re: Can Google Apps Account be an Administrator?

[Marzia Niccolai]

Hi,

If you reply to me with the email addresses and app id I can further
investigate the issue.

It is important, in general, that you not be logged in to a Google Account
and Google Apps account at the same time when accepting an invitation to
develop.

[google-appengine] Re: lots of datastore timeouts in our app

It's happening with one of my apps as well. It seems somewhat
sporadic.

Looks like I will have to track it down. Would be nice if we could set
the version we are using.

[google-appengine] Re: Is there a way to get the Clients screen size with Appengine?

[Andrew Badera]

Google Analytics does it with JavaScript.

The information has to be sent by the client. If they're calling a web
page, you can put JavaScript on it to obtain this info.

[google-appengine] Random 404 errors returned for static content

[Matthew Trinneer]

Hi All,

Today I've been receiving 404 errors when fetching static content.
These occur randomly, perhaps once every 30 requests and exhibit no
apparent pattern that I can discern.  The errors occur on random
documents, like fetching an image or JS script.  A request sent
immediately after the 404 for the same object will 9/10 times return
without error.

Anyone else seeing similar behaviour?

Thanks, Matt

[Jyoti Shete-Javadekar]

Hi Venky,

I am assuming that your local server works fine without "-a" option. I can't
think of any reason why adding "-a" option results in an error.
You could try following things though:
1. Use "--address 0.0.0.0" instead of "-a0.0.0.0"
2. Check if you have the latest version of the app engine sdk.

applications , I wanted to try the google app engine a few days ago
and I prompted to enter my phone number to receive a SMS code , I did
just that but my number was not accepted , I went to the FAQ and made
sure my carrier is supported (IAM) , tried again but no luck .
As a note a few days ago (March 7th) all carriers in Morocco ,
including IAM and Meditel , have changed the number of digits in a
phone number from nine to ten . So my phone number which was +212
061xxx273 is now +212 0661xxx273 (the x are there because I don't want
to disclose my phone number) . I tried with my old number and it was
accepted , the problem is I don't receive any message of course , so
it seems that google has not updated to reflect these changes in the
number of digits here .

Is google aware of this ? and is this going to be solved soon ?

PS : I hope I'm writing in the right forum ... I did not find any
other mean of contact other than this one .

[google-appengine] Re: how to config gwt to work in app engine effective and productive

[Pavel Byles]

Well, you can use django (or not) to convert your data from the
datastore to json format. Not _actually_ pass the objects themselves.

[google-appengine] Re: Is Google App Engine support UDP communication? I know it is support tcp like http.

[Mr Blog]

Not only can you not do UDP.  You can't even really do TCP.  All your
apps can do is HTTP over port 80 (port 433 SSL).  You can even do HTTP
over alternative ports.

[google-appengine] Re: Request time limit

[Tim Hoffman]

I noticed you posted the same question to nltk group,
if you are planning on using nltk I think what i said earlier won't
work
if you are planning on using nltk to process the text,

you may need to do some rethinking on your approach

[google-appengine] Re: Request time limit

[Tim Hoffman]

Yep sure is

I suggest you start with 
http://code.google.com/appengine/docs/python/gettingstarted/usingdatastore.html

Then look at the full datastore api at 
http://code.google.com/appengine/docs/python/datastore/

good luck

[google-appengine] Re: Forward request or webapp.RequestHandler chaining (like Actions framework in java)

[Serega.Sheypak]

Yes, Java made my mind tooo complicated. You've  written clear
solution: invoke one handler from another.
That is why I've immediately started to learn Python+ GAE (wow), Ruby
+RoR (awesome! cool!) and Lisp(brain blast) .

Java made my mind Javable... :(

[google-appengine] Re: Request time limit

[Tim Hoffman]

Hi

Ok, that better much more info ;-)

Really you should create model objects which representing
chapters, verses and parallel translation of each verse, along
with appropriate metadata or references that will allow you to find
the
appropriate translation.

Whilst you example might have worked in dev (thats because dev doesn't
enforce transaction/request limits)
you really have no chance of getting this application to scale.


There is another way, (but gae is really designed for what I described
earlier)
You could preparse all the chapters and verses in to the dictionaries
as you are currently doing
offline, (ie not even under the dev server) then write those
dictionaries as strings to files so that the output is something like
as follows

for instance. file mybook.py contains the following

book = {'chapter1': {'verse1':'some text'}}
(I have left out lots of data ;-)


Then in your code you could import  mybook e.g.

import mybook
mybook.book['chapter1']['verse1']

But really you should learn all about models ;-)

See ya

T


Then you could import the module

[google-appengine] Re: Chartle.net - application based on Google App Engine

[Dieter Krachtus]

That's pretty easy to do. I registered my domain chartle.net with
Google Apps. After that it is just a few more settings via the Google
web interface.

Whats a little annoying is that you cannot use so-called 'naked'
domains, i.e. in my case 'chartle.net'. I can only use www.chartle.net
and other subdomains.

Well, that's the one major limitation I dislike in Google Apps. Same
with Google Appengine, where I cannot specify Content-Encodings. Very
annoying for my purposes. Also the 1MB filesize limit hurts a bit.

Otherwise both Google Apps and Appengine are really great services.

[google-appengine] Re: how to config gwt to work in app engine effective and productive

[Serega.Sheypak]

Of course not.
You can *present* datastore object in JSON (JavaScript Object
Notation).
Use POJO (Plain Old Java Object) concept while creating data Model of
your application.
You can easilly present list of Model objects in JSON, you can easilly
convert them from JSON to POJO on GWT (Java, client-side). The same
thing happens on server-side. Parse incomming JSON and construct Model
objects (in Python) using parsed data.

GWT+GAE can work together. Ofcourse, this way won't be productive
comparing to Java backend. But anyway, if you want to make good stable
complicated UI, don't use JS - it's paiful. Use OO Java and be happy
like I am ^)

[google-appengine] Re: Request time limit

[Nora]

My application is a keyword search query tool that uses the
Quran.  I am loading 2 copies of the English Quran(where every verse
has eight parallel english translations) and two Arabic copies of the
Quran.  The Quran has 114 chapters and the longest chapter has 285
versesjust to give you an idea of the size of the data that needs
to be loaded.

Does that help at allI am really stuck into this as the
application worked fine on my computer before uploading it to the
server but now it is not!!  very disappointing and I have little
background about databases and datastores and how to search these
structures


Thank you very much for your great help,

Nora

[google-appengine] Re: Request time limit

[Tim Hoffman]

for instance you could preparse these text files and generate python
code
which you would just import

What sort of data  do you have in your text file and how do you plan
to use it ?
How many records (dictionary keys and values) are in these text
file ?

That would help me formulate a clearer example.

However do you really need all of that data in memory for every
request?

Now, I am interested in your second option but could you make it

[google-appengine] Re: how to config gwt to work in app engine effective and productive

[Pavel Byles]

Coonay,
I use GWT and GAE together and I think it's a pretty good setup.
First, instead of using servlets you will use the request builder and
pass data using JSON instead. 2nd I effectively just send my HTML
output of my GWT project to my GAE project and configure my app.yaml
accordingly.

Using this method you will lose a really big part of GWT, which is the
debugging feature since you will be running dev_appserver. Unless you
can fix it such that u can get JSON responses from it.

But I like my setup. I have pydev and cypal both in eclipse. I just
wish i had debugging somehow.

[google-appengine] Re: Request time limit

[Tim Hoffman]

Why do you need to load that much data into memory on each request
if you are creating a dictionary you could

1.  create model entities for each dictionary
and load them as required by their key

2. preprocess the text files into dictionary code and import them

[google-appengine] Re: Parallel urlfetch utility class / function.

[Joe Bowman]

Thanks,

I'm going to give it a go for urlfetch calls for one project I'm
working on this week.

Not sure when I'd be able to include it in gaeutiltiies for cron and
such, that project is currently lower on my priority list at the
moment, but can't wait until I get a chance to play with it. Another
idea I had for it is the ROTmodel (retry on timeout model) in the
project, which could speed that process up.

[google-appengine] Request time limit

[Nora]

Hello,
My application needs much time to load some text files into
dictionaries in memory.  I am unable to load all the data because of
the request time limitation.  Is there another way of getting around
this?

Thank you very much.

[google-appengine] Re: how to config gwt to work in app engine effective and productive

[lock]

I'm a big GWT fan, never done much with javascript and don't
really want to!  It's just a personal preference, not wanting to start
another java vs javascript thread ;-) .  Sounds like your coming
from a java desktop background, there's a bit to learn, but it's
pretty straight forward.

Tim's right, GWT and App Engine are completely different bits
of the puzzle.  GWT is all client side browser stuff, App Engine
is server side.

All the HTML/javascript code on my site is static, it isn't
dynamically generated on the server. No, not even the URLs the
app requests data from change.

You probably want to look at the REST architecture concept, it
basically states that the client should manage state (not the
server).

I use the JSON format to transfer data from the client to the server
and back again.  This is done using a variety of HTTP requests, GET
for requesting data from the server, PUT for changing server data.

Eclipse works really well for GWT projects, and if you install the
PyDev project it does a pretty good job with app engine too.  I use
the same workspace for both client and server code.

There really is an awful lot more too it, strongly suggest having a
look
at some of the great app engine tutes.

 I know that one of the requirements to run GAE is to have at least
 Python 2.5. Don't go running to Python 3.0 though just quite yet for GAE.
 It's not supported AFAIK.

[google-appengine] Re: how to config gwt to work in app engine effective and productive

[Tim Hoffman]

Hi

gwt has on the surface nothing to do with gae, ie you can't run the
java server side of
you gwt code on app engine.

Have a look at pyjamas if you want something like this (backend is
python though)

You will need to learn python to get anywhere with gae, unless google
release java support.

My guess it is more likely to be ruby or javascript for the next
language,

in fact I personally think the next language supported by gae will be
javascript
it would make sense given googles development of v8.  (I know nothing
on this topic though ;-)

Just my 2c worth

I've just read the "Latency Issues Stabilized" notification and I'd
like to firstly thank you for taking the time to explain the problems.
Anyways, I'd also like to point out that the 2 messages in the thread
are not clearly stating if the problem is 100% solved.

While the first message in the thread (dated Mar.5) mentioned that:

[quote]
Performance has greatly improved. Latency does remain
slightly higher for some apps, but all spikes and errors have been
contained at this time. System performance should remain stable
throughout the weekend and improve further at the beginning of next
week.
[/quote]

there is no clear indication in the second message (dated Mar.16) if
the issue is solved and if the latency is completely back to normal.

cheers,

 As a many years java progammmer,it's not hard to get into gwt,but the

 the hype link in the geranated html are needed to change accordingly.

  The Development Environment
  You develop and upload applications for Google App Engine using the App 
Engine software development kit (SDK).

  The SDK includes a web server application that simulates the App Engine 
environment, including a local version of the datastore, Google Accounts, and 
the ability to fetch URLs and send email directly from your computer using the 
App Engine APIs. The SDK runs on any computer with Python 2.5, and versions are 
available for Windows, Mac OS X and Linux.

  If necessary, download and install Python 2.5 for your platform from the 
Python website...

  
http://code.google.com/appengine/docs/python/gettingstarted/devenvironment.html

  You need to have Python 2.5 and you only have Python 2.4.5 installed.

  I know that one of the requirements to run GAE is to have at 
least Python 2.5. Don't go running to Python 3.0 though just quite yet for GAE. 
It's not supported AFAIK.

[google-appengine] Re: Efficient paging using __key__ instead of a dedicated unique property

[Simo Salminen]

Hi.

Just for the curiosity, I did a simple pagination algo which supports
'previous' button. This is not as fancy as rodrigos, because this is
not generalized for all types of queries. Also it is bit repetitive
because I wanted to keep it easy to understand.

Here is the code:
http://pastebin.com/f66e901b1

It assumes following data model:
 class Issue(db.Model):
whatever = db.StringProperty()
modified = db.DateTimeProperty()

It does sorting based on 'modified' field. The bookmark is (modified|
__key__|direction), where direction is either 'prev' or 'next'. Note
that because it needs to figure out if there are previous and next
pages, it has to do total of 3 queries per page view. I could not
figure out better way to do this.
