[Nitin Shrimali]

Hello Friends
I am using python twitter api in appengine but on executing
it it is giving me


NotImplementedError at /monitor-twitter

Only tempfile.TemporaryFile is available for use

 Request Method: GET  Request URL:
http://localhost:8081/monitor-twitter  Exception
Type: NotImplementedError  Exception Value:

Only tempfile.TemporaryFile is available for use

Hi Venkatesh,
What is the full query that your trying to execute that is giving the
error? If it's not a field that contains multiple values I'm not sure
what that type of index would do since a single value property would
have the same value repeated again and again in the index. What am I
missing?

Got this one solved by defining a transformer for the model instead of
the kind.

Re: [google-appengine] Re: Help with data-store statistics

[Venkatesh Rangarajan]

Stephen,

Yes, that is correct. I have only one index. I am not doing any
sorting or filter or anything.

Total size of all records is close to 1 million records.  Raw data
size is i think 500MB. I had uploaded part of the data when Appengine
launched. Abandoned it frustrated with data time out and lack of
search etc. Thought it would be a good time to re-try.

I don't have multi-property field.

I did not have too create that index, it was added in the index file
automatically because I am using Searchable Model. Now inspite of
this, i kept getting the following error.

NeedIndexError: The built-in indices are not efficient enough for this
query and your data. Please add a composite index for this query.
This query needs this index:
- kind: Jobs
  properties:
  - name: __searchable_text_index
  - name: __searchable_text_index
  - name: __searchable_text_index
  - name: __searchable_text_index
  - name: __searchable_text_index


I manually added, that to index file and that resulted in exploding
index. That index error-ed out and I have vacuum it long back.

None of this explains how 1gb of data gets translated to 28gb of data
in appstore. I have another 3 gigs of raw data, sitting on my
hard-disk which i am afraid to upload, since I am not sure it would
scale.

rgds,
Venkatesh

[google-appengine] Re: Help with data-store statistics

[Stephen Johnson]

Hi Venkatesh,
When you say you have just one index, does that mean you set all the
other properties to be unindexed? If not, you could have other indexes
that are adding to your total. What kind of data is stored in the
__search_text_index property and what would you say the average size
of that data is if it is text data or number of properties if it is a
multi-property field and how many unique values would you guess that
that property contains? Since you're using that property twice in the
index, my guess would be that you've got some kind of multiplier
effect going kinda like an exploding index (
http://code.google.com/appengine/docs/java/datastore/queriesandindexes.html#Big_Entities_and_Exploding_Indexes).
I'm curious to see what your answers are to these questions since I
think a lot of us are interested in watching our data usage.

[google-appengine] Re: I can see some of my source code files with Appstats

[Albert]

Thanks!

I agree with you, Brian. It should be mentioned in the Appstats
documentation that it would possibly leak some source code.

If you want to sell applications as "close source", I think you just
have to remove Appstats. Or maybe Appstats can have an optional
configuration to not display source code.

Thanks for the replies!

[google-appengine] Help with data-store statistics

[Venkatesh Rangarajan]

I have uploaded about 1GB of text data. It shows as 28GB on the
dashboard. Here are the statistics

Breakdown by Property Type
Property TypeSize
String825 MBytes
Integer8 MBytes
Date/Time42 KBytes
Float3 KBytes
Metadata6 GBytes

Total number of entitiesSize of all entities
1:50:59 ago 984,006 7 GBytes

I can understand that 1 GB can become 7GB with all the meta-data and
stuff ( which is still high) , but why is the dashboard showing 28GB
and billing me for it ?

I have just one index.

With all due respect, you are stating the obvious and the use case you
present is like a text book example of last in first out/race ahead
condition. Perhaps if the coder had declared the static variable final and
initialized it in a static constructor it would have prevented multiple
assignments - assuming a single class loader of course and a single class
cache.

Not that your point isn't valid. One does have to take care when using any
language feature, Java or any language for that matter. That is obvious I
hope.

In any case I wouldn't advise anyone from avoiding using static class fields
if it fits their use case. With care they can and are used without any
problems.

[google-appengine] Re: Is it really bad to define global variables?

[Stephen Johnson]

Hi Jeff (and possible Bill if you're using Java and not Python (not
sure from the question since I don't know Python))
(Assuming Java) Using static variables could cause all kinds of
trouble if proper care is not taken to limit their accessibility since
they are shared and all requests that are being handled by that
particular JVM instance be accessing the same data. That data would be
accessible for simultaneous requests and would also survive after the
requests have finished processing and would be available to the next
request(s). This data would exist until GAE shutdown that particular
app instance on that JVM (or restarted due to a deployment, etc.)
Other JVM instances of the app would have different values.

So, for example, if we have:

public class Beta {
   public int x;
}

public class Alpha {
  public static Beta beta;
}

So if Servlet #1 receives a request and does:

  Beta b = new Beta();
  b.x = 5;
  Alpha.beta.x = b;

And then Servlet #2 receives a request and does:
  Beta b = new Beta();
  b.x = 17;
  Alpha.beta.x = b;

And then Servlet #1 continues processing:
   b.x = b.x + 5;
   ***  Oops! b.x is now 17, not 5 ***

Also, this Beta object will exist even after the requests have all
finished since the static instance will stick around. Note, that this
occurs even though these objects are not Serializable.

So, Jeff in response to:
> If storing values in class static fields were problematic I'd guess that
> this would break quite a number of web apps. What do you think?
Well, static variables are by their very nature are supposed to be
shared and are not a problem if used correctly and for that purpose,
but in Bill's case he would be attempting to use a shared variable as
if it were a private variable accessible only to a particular request
and so would be used incorrectly and could cause problems for his web
app.

Okay, so static variables may not be ok. What about storing the data
in an instance variable of the Servlet?? Well, that wouldn't work
either since the servlet container only creates one instance of each
servlet class, thus the instance variables of the servlet classes act
almost like static variables, that is, they are shared amongst all
requests to that servlet and would survive even after the requests
have finished processing since the servlet container will keep the
servlet instances alive until the servlet container shuts down.

So, if Bill is using Java, then what should he do. Well,
1.) I'm not sure why you have to re-sync the object A that is passed
in the constructors of the other objects with the handler's object A.
In Java, these would be the same object unless you are making some
sort of clone (or copy). So, I think your approach works. At least for
Java. Unless you've left some detail out.
2.) So what you can do is you can use the ThreadLocal class to store
object A. The ThreadLocal class acts like a Map but the values are
specific to each thread and other threads don't see each other's
values. So, at the beginning of the request you can store object A
into the ThreadLocal object and then objects B, C, D, etc. can access
that object by key. One caveat is that these values would be available
to the next request that is handled by that thread so you'd need to
make sure you clear these values at either the ending or beginning of
each request.

[google-appengine] Re: Same CNAME domain in multiple accounts

[Dre]

Yes, this would work for deployment in a small group, but this doesn't
work so well for Enterprise deployments where multiple teams are
involved. In our deployment workflow we have separate teams taking
care of dev. vs. production applications.

In order to push an app to production our Production team takes the
application from the Development environment (once tested, QAed, etc.)
and then pushes it out to production. They want to make sure that no
one, except those that are supposed to, can touch production
deployments.

In the scenario of having two apps under the same account, there is
still the possibility that out of say 10 developers working on the
application, one could mistakenly (or potentially on purpose) work
with the wrong application. Maybe there are more knobs and switches
there for access control which I haven't explored?

Also, we would like to separate costs between what our production
environment is using and what our development environment is using.
I'm not very clear if this information is readily available. Since
we're still in our free quota I'm not clear on how this is can be
accomplished either and separate accounts would also help...

[google-appengine] Re: Same CNAME domain in multiple accounts

[Roberto Saccon]

maybe I am missing your point, but you can publish your app with two
different applications, stable versions two one app-ID, unstable ones
with another app-ID. Then you map the stable app to www.example.com
and the unstable one to dev.example.com

Re: [google-appengine] Re: Access from Israel

[Ikai L (Google)]

Can you guys provide us with this information? Email me directly if you
don't want to expose sensitive info:

1) Your IP address (This works pretty well: http://whatismyipaddress.com/)
2) Do a DNS lookup of www.appspot.com (From the command line - in Linux/OS
X: nslookup www.appspot.com, in Windows just do a "ping" and it should show
the address, I don't remember if there is a Windows analog)
3) traceroute to ip returned from dns for www.appspot.com (From the command
line - Linux/OS X: traceroute www.appspot.com, Windows: tracert
www.appspot.com)

We thought we figured out what the cause of this was, but it seems like we
were mistaken. We'll contact Bezeq once we've determined what the issue is.

[google-appengine] Re: Google Account

[Geoffrey Spear]

You probably don't want your user to be logged in using Google's
servers and then get redirected to localhost.

Use the Users API to generate the login URL.

[google-appengine] DatastoreNeedIndexException: no matching index found.

[Coutinho]

I have an index serving like the following:

FoodCategory
isMainCategory ▲ , name ▲   Serving

And I have the following query:
select from FoodCategory where isMainCategory=true order by name

However i always get:
com.google.appengine.api.datastore.DatastoreNeedIndexException: no
matching index found..

Why is that?

another question is, i don't know why the auto index file created 2
indexes one for FoodCategory and another for the same but all upper
case FOODCATEGORY

[google-appengine] Same CNAME domain in multiple accounts

[Dre]

Hi,

I would like to separate out our dev and production accounts for App
Engine so that developers can safely use the dev account without
affecting production. For each account I would like to have well known
names for the applications under the same domain. For instance:

dev account -> dev.example.com
production account -> www.example.com

To create these CNAMEs I need to register the domain under the same
account in Google Apps. However, I can't seem to register the same
domain under two different accounts so I cannot set this scenario up.

Is there any way to get around the requirement of using Google Apps to
register the domain? Not sure why I need to prove I own the domain if
I have the power to setup the CNAMEs with my DNS provider anyway.

Maybe there is another accepted workflow on how to separate dev. and
production environments?

Thanks,

Dre

[google-appengine] "too many indexed properties" from bulk loader

[rw]

I have an entity with a ListProperty that can have many entries.  When
calling put() on one of these entities I originally got the "too many
indexed properties" error message, and resolved it by adding
indexed=False to the property.  Now however when I try to load the
same data using the bulk loader I get the error again.  Is there an
option for bulkloader.yaml that I'm missing?

Thanks!

[google-appengine] Google Voice on the health status dashboard

[Greg]

Hello,
Not sure if this is the right group to post this to, but was curious
as to why Google Voice is not on the Google uptime status dashboard,
e.g. http://www.google.com/appsstatus#hl=en

[google-appengine] Re: Can we run PHP and Ruby on AppEngine

Attention
PHP supported by Quercus doesn't imply that all the library and
extensions supported by PHP are supported on GAE... it just imply that
the language is supported
and there is a lack of information on supported extensions (XML?

I wasn't the original poster but I was curious about your caution regarding
class static fields.

Which Python framework are you using if you don't mind me asking?

And that means that the admins of the application that is sold as

These non-developer admins only should be able to manipulate the datastore.

Wouldn't have a clue.  I don't use java on appengine. You didn't
mention in your original
post you where  specifically talking about java.

In python class/module cached definitions last for as long as the app
instance is running.

Re: [google-appengine] Re: Is it really bad to define global variables?

[Jeff Schwartz]

Hi Tim.

Help me out here 'cause I don't understand what problem you see with storing
a value in a static field?

As far as I know (and I am limiting my discussion here to Java and servlets)
objects are not persisted across http requests unless they are serializable
and stored in session or in memcache and that takes programming effort
meaning you have to deliberately program the behavior.

Yes there are statefull web frameworks such as Wicket and JSF for instance
that will persist objects accross requests without programming effort but
even these are limited to model and view class instances for the most part.

As for classes (not instances) persisting across requests (and eliminating
those classes that are servlet and other server pluming classes) what
classes are persisted across requests?

If storing values in class static fields were problematic I'd guess that
this would break quite a number of web apps. What do you think?

That's right. According to the appstats docs only admins should be
able to see the appstats web interface and the source code of your

[bFlood]

I'm pretty sure only admins can see appstats but if that's not enough,
you can alter the main appstats handler to only accept a specific user
(I did this for our app). Drilling into the source is sometimes pretty
helpful

I do agree that somewhere in the appstats docs they should mention
leaking source code.

[google-appengine] Re: Is it really bad to define global variables?

[Tim Hoffman]

The biggest problem I see with storing the value at a class/module
level
is you really need to make sure you clean up after yourself, otherwise
the
value may still be set when the next request is processed and that
value may not be
appropriate.

I would personally always grab/cache values in request object,
memcache, and or session
as appropriate.

That way there is no danger of exposing data to other requests.

But hey, if you want to use module level caches go for it.

I have been running appengine projects ever since it was released and
started out with some
module level cache, and regretted it ever since.  It was has proven to
be difficult ensure the cache
has been cleaned up, where as memcahce you can control out of
process.  (You can't shut an instance down
if it has an error and you can't remove a value from a module cache)

Re: [google-appengine] Is it really bad to define global variables?

[Jeff Schwartz]

Use session state to store values that are unique to each user. Use memcache
to store values at the application level that are share among all users.

Session state will persist your data across requests. Memcache can do
likewise but its memory can be reclaimed by the system so there is no
guarantee that you will have access to your data and you have to be prepared
to recreate it.

Also keep in mind that both session state and memcache have limits on the
amount of storage that they provide which you can find in the documentation.

You can also use the datastore but that comes with a whole different set of
issues and I wouldn't use it as a temporary cache if there were better
alternatives.

I always look for the simplest solution and if I only needed to store data
within a single request I would use an instance reference or a class
reference depending on whether or not the data is a singleton or not.

If my needs extended beyond a single request I would use session or
memcache.

Re: [google-appengine] Is it really bad to define global variables?

[Alon Carmel]

Why not save it to session then?
Why not use memcache?
Isnt static classes for that? if you run it at the start it will run once
for all users and you can call it over and over with the same return. no?

[google-appengine] Is it really bad to define global variables?

[Bill Edwards]

Hey guys,

Is it horrible to use global variables?  I am currently executing a
query at the beginning of my handler and storing the query result
within class object A.  I subsequently need to access the query result
within multiple different class objects, say B, C, and D.  It has been
recommended to me to cache object A in the request object, but i need
to access the variable from within various class objects, so I'm
finding that I have to pass the object A in to the constructor for
every new object i define, and then sync any changed state of object A
with the handler's version of object A when the various class object
functions are completed.

So it really seems like the simplest way to do things is to just
define a global variable.  Is there a better option?  Can I think I
would ideally want to create something liek a session object to store
the global object.

Thanks!
Bill

Re: [google-appengine] HardDeadlineExceededError

[Alon Carmel]

i had that exact problem.
I resolved it by cutting down the amount of processing from one process to
tons of them.
You can break all the mini calculations into mini tasks running asyc side by
side and get the work done at the same time or even shorter.

If tasks isnt the solution for you try the mapper class, google for it. it
lets you catch the HardDeadlineExceededError and save your current job
location and restart again at the same position.

quick tip from what i've learned. google gives you extra few seconds before
they break your process with HardDeadlineExceededError, its not something
static but its around 2-3 seconds, you can do alot when you hit that. do
try: catch on that and test it.

For large datastore uploads and so on use the bulkloader tool.

[google-appengine] Re: I can see some of my source code files with Appstats

[Albert]

Hi!

I just wanted to bring it up again.

I can see some of my source code files with Appstats.

Most of which are the python files in my application.

Is this expected functionality?


Thanks!
