[google-appengine] charges

[tony gair]

I am writing a google assistant project that I hope will one day will buy 
me an electric bicycle. The project is one where you talk to and get the 
information you require from a speaker talking to you. 
I have recently been coding up the database side of the project and 
realise I have a lot of data to put in google datastore. I am more than a 
little concerned having had to set up credit card billing that I get stung 
rather than get a few quid.
 Hey Google can you reassure me on this?

[google-appengine] Re: GAE Search API - Python

[Tony Indrali]

Hi,

To make it very clear, the original App Engine APIs, specifically the *Search 
API* (https://cloud.google.com/appengine/training/fts_intro/), is planned 
to be made available to Python 3.7 standard environment App Engine?

Thanks in advance.

[google-appengine] Trying to mount Google Filestore share in GAE flexible runtime container

[Tony Day]

Hi

I would like to mount a Google Filestore share so that I can write files to 
it from my app running in a GAE Flexible docker container.

As a crude experiment I have SSHed into the GAE host instance and manually 
followed the steps outlined here 
 to mount the 
share in the docker container.
This works (sort of) but only if I manually run the container with the 
appropriate privilege (for example docker run --rm -it *--cap-add sys_admin* 
 /bin/bash).

Is it possible to configure GAE Flexible to run the gaeapp container with 
specific properties (for example --cap-add sys_admin) ?

Alternatively can anybody suggest a better way to mount the Filestore share 
on the gaeapp container.

Many thanks

[google-appengine] what's wrong with my domain: http://35.199.179.111/wp-login.php?redirect_to=http%3A%2F%2Fwww.naturalherbalcoloncleanse.com%2Fwp-admin%2F=1

[tony wang]

Hi there,

I just bought a domain from NameCheap and pointed it to my google cloud

If I type my domain: www.naturalherbalcoloncleanse.com, it works fine.

but whenever I try to type in: www.naturalherbalcoloncleanse.com/wp-admin, 
it will go wrong something like this:

http://35.199.179.111/wp-login.php?redirect_to=http%3A%2F%2Fwww.naturalherbalcoloncleanse.com%2Fwp-admin%2F=1

Can someone please help me on this?
thank you
tony

[google-appengine] Datastore on flex nodejs appengine isn't working

[Tony Stark]

Since yesterday does not work datastore through the flex evironment. 
Application just not receives the response from the datastore. If I run the 
application locally, everything works. If I try to do those operations in 
app engine - it does not work. The answer does not come from the server. If 
wait a long time, the message from the nginx is  "502 Bad Gateway".

There are no errors in the app; it works locally. And even before yesterday 
everything worked perfectly in the app engine.

https://lynkus-api-test.appspot.com/test - here is no request to the 
datastore, the answer comes from the application.
https://lynkus-api-test.appspot.com - here is a request, but there is no 
answer :(

if you go in the app engine instance, in /var/log/nginx/error.log there are 
reports like this:

2017/02/01 09:15:59 [error] 32#32: *736 upstream prematurely closed 
connection while reading response header from upstream, client: 
130.211.3.225, server: , request: "GET / HTTP/1.1", upstream:

[google-appengine] Reliability of urlfetch when dealing with servers in China?

[Tony Yang]

I am creating an app involving urlfetch with China servers, and I am aware 
that google IPs are generally blocked in China.

Now based on my test results, urlfetch to China websites works without 
errors.

My question is, does that happen most of the time? And, if one day, China 
blocks urlfetch's source IPs (since it comes from a small range and 
probably don't change so often), will Google be responsible to change the 
IPs so that urlfetch can work normally?

In theory Google can choose from a very large pool randomly for urlfetch or 
just do urlfetch from the crawlers' IP. China won't block them.

Cheers,
Tony

[google-appengine] Bad deploy day... again

[Tony França]

This is getting really annoying.
Bad deploy days have been a recurring issue for us (please see 
https://groups.google.com/forum/#!searchin/google-appengine/qmagtest)
I also opened an issue on appengine issue tracker: 
https://code.google.com/p/googleappengine/issues/detail?id=9917thanks=9917ts=1378228556

Google, please do something about this!

Is anybody else having theses problems?

Also, I'd like to suggest that Bad deploy days be shown on Appengine 
status page - https://code.google.com/status/appengine/
That way I can get a feeling whether this is happening to a lot of people 
or it's just me.

[google-appengine] push to deploy is broken (repository 'https://code.google.com/id/xxxxxxxxx/' not found)

[Tony França]

For some time now, we have been having problems with 
deploymenthttps://groups.google.com/forum/#!searchin/google-appengine/badstatusline/google-appengine/9e2mI5YEocI/jzktdq9n538J
.

I though I had finally found a solution using 
push-to-deployhttps://developers.google.com/appengine/docs/push-to-deploy, 
but it just stopped working.

The Git repository that I'm supposed to push to doesn't seem to exist 
anymore.

I tried disabling and re-enabling push-to-deploy in the app settings.
According to the instructions in the app-settings:

*Note:* If you disable this feature and re-enable it, a new empty Git 
 repository will be created, and the contents of the original one will be 
 deleted.


But when I try to clone the new repo:

$ git clone https://code.google.com/id/AMwlKnyGF-Z/
 Cloning into 'AMwlKnyGF-Z'...
 fatal: repository 'https://code.google.com/id/AMwlKnyGF-Z/' not found


please help.

The app_id in question is *qmagtest*

Thanks

[google-appengine] Re: Deploy issues

[Tony França]

Hi Chris, we're experiencing those same deploy problems again today.
We have a Jenkins installation that allows for one click-deploys, 
This Jenkins job normally takes about 5min to run. It runs automatic tests, 
and does the deploy if they pass.
On healthy builds, about 80% of those 5min is spent running tests. 
Deploying is normally the fast part.

Below there's a few details for the failing builds we are seeing today.
All deploys attempts are for app_id *qmagtest*

You can see that those failed builds are taking a longer time. That is time 
spent during the deploy attempt.
I hope this helps you trace the problem. Please let me know if you need 
more details.
Thanks

[google-appengine] Re: Deploy issues

[Tony França]

Having the same issue as Renzo with our Python app.

Actually sometimes the stack trace is different, besides the 
BadStatusLine, we also get the stacktrace below.
I strongly believe this has nothing to do with my internet connection.

Google, any comments on this?

Thanks 
Tony

[google-appengine] Re: Every day around 9.10 AM Brussels time, huge drop in GAE performances

[Tony Lock]

I too am having the same issues. At approximately 4:00pm West Australian 
time, the application starts to misbehave. I am starting to see latencies 
around the 70,000 ms mark, and lots of deadline exceeded errors. Most of 
these are at simple page load steps, not even doing real processing. The 
application is unusable for about 45 minutes to an hour, every day.

It has been consistently bad for about a month now.

[google-appengine] No entities persisted when using JPA + Datastore

[Tony Piazza]

I am trying convert a Java project using JPA/Cloud SQL to use JPA/Datastore 
instead. I see these messages in the log when running the application:

I 2012-11-26 19:39:13.660 org.datanucleus.TransactionImpl 
internalPreCommit:  calling preCommit on 
org.datanucleus.store.connection.ConnectionManagerImpl$2@17a0b4d

The problem is that I don't see the entities that should be persisted. The 
Datastore Admin says Datastore is empty and the Datastore Viewer can't 
find any kinds associated with my entities. Any ideas as to what might be 
wrong?

Thanks in advance for your help.

[google-appengine] Redirect loop on app deployment

[Tony Carden]

Hi folks,

I'm completely new to app development and to this forum, so please forgive 
both my ignorance and any incorrect use of this forum. I've just deployed 
my first app, which runs fine on my local machine, but which gets stuck in 
a redirect loop when deployed. I've used a version of the user 
authentication system advised here 
https://developers.google.com/appengine/docs/python/users/overview, with 
some modifications to incorporate jinja templates.

Is this a common problem? Should I post my code so you wise folks can see 
what I have or haven't done?

Thanks in anticipation,

Tony

Re: [google-appengine] Inaccurately Over Quota

[Tony Parisi]

I wasnt on the razors edge... is the point My daily spend is $0.60 plus my
prepurchased instansce hours spend. Beyond the front end hours I have 2-3
cents a day on database reads. The problem is the prepurchased instance
hours are calculating into the daily spend even though when you set your
budget they do not. We are a not for profit preschool so having a budget is
very import to anticipate expenditures.

 app wont be served any more.

[google-appengine] Is it possible to query Datastore by parameter of Date?

[Tony Yang]

Dear Sir,
Would you help the issue below. Is it possible to query Datastore by
parameter of Date?

--- My code 
PersistenceManager pm = PMF.get().getPersistenceManager();
Query query = pm.newQuery(Customer.class);
Date currentDate = new Date();
Date beforeDate = new Date();
long currentdate = currentDate.getTime();
long beforedate = currentdate - 8640*5; //search data in
Customer.class within 5 days
beforeDate.setTime(beforedate);
query.setFilter(date  offsetDate); // date is
column's name in Customer.class
query.declareParameters(Date offsetDate);
ListCustomer conn = (ListCustomer)
pm.newQuery(query).execute(beforeDate);

--- Error message from system is as below :

Class Date for query has not been resolved. Check the query and
any imports specification

Thanks a lot.

[google-appengine] The price of Scalability

[Tony]

I just read this post http://www-cs-students.stanford.edu/~silver/gae.html 

The author seems unhappy with App Engine's offerings and have switched to 
EC2, saying when the app scales big, the cost is very high (he used the old 
Master/Slave datastore with high latency counted against CPU time).

I myself like app engine a lot because from what I heard it offers good 
scalability without complex setup and maintenance. But I don't have much 
experience with it to say if the claims in the above post are true. 
Especially now there are changes in pricing, I'm afraid the costs may be 
driven a lot higher. 

Can anyone who is having a popular app on app engine give me your thoughts 
on the post? Do you see the new pricing scheme make scaling app a lot more 
expensive?

[google-appengine] Re: Text files bulk upload : any advice ?

[Tony O Dowd]

Hi there, this might be helpful. I've recently developed a file
uploaded for an crowd source application I'm involved in and have used
a DiskFileItemFactory. Once you create a factory object you can set
the size of the files that are to be uploaded. Bt default it's 10K but
you cN manually set this  for smaller sizes. here is some code
snippets that may be helpful :-


DiskFileItemFactory factory = new DiskFileItemFactory();  // create
the factory for file uploading
factory.setSizeThreshold(Memory); // this sets the threshold for files
to be held in memory or stored on disk
factory.setRepository(server folder); // defines the location on your
server where the files are to be stored

You  should use this in conjunction with a ServletFileUpload object so
you can bulk load multiple files to your server.

Hope this is helpful,

T.

 I've been thinking to merge them into one big file to split then later
 in GAE. But I would rather not do it this way, unless you have a nice
 technique to handle that. They all have special characters of all
 kinds and unicode...

 Do you have any suggestion ?
 Thank you

[google-appengine] Re: Just a little help

[Tony O Dowd]

Are you using Python or JAVA to build your servlets?

If You're using Java you need to define your servlet in your web.XML
file. You simply define the servlet name, the class it points to and
then the mapping of the servlet name to it's URL. If you checkout the
default web.XML file that is created when you build the default GWT
app in eclipse you'll see a good example of this.

 Could someone give me some advice?

[google-appengine] Redirecting to a web page from a servlet

[Tony O Dowd]

Im calling a httpservlet from a GXT FormPanel using the usual
FormPanel.submit() method. This calls the doPost( request, response)
method of the httpservlet. Im using Submit as I'm uploading data to
the sever from a client using a FileUploadField in the FormPanel.

My problem is that by using FormPanel.Submit(), the browser opens a
new tab and  jumps to the HTML page of the httpservlet, thus changing
the focus from my GXT main application running in the browser.

anyone know a neat solution to prevent this and maintain the focus in
the main GXT application tab?

Thanks in advance.

[google-appengine] Datastore Copy to Another App freaking out - 20 callback requests per second

[Tony Blank]

Howdy,

I fired off a copy job to back my data up 3 days ago. I notice that my
app activity has shot through the roof since then. It seems as though
one of the mapreduce copy jobs is looping... It's doing 20 or so
callback requests per second.

I have the mapreduce job ID - any way for me to manually kill it? Been
searching around and I haven't found a way to do that. Anyone have any
ideas?

Awesome, thanks!

Tony

I've created my first App on the Google App Engine and everything went
well, however, now when I try to create a new application it asks me
to Verify my Account using SMS. As I've already done this previously,

using other phone numbers but it just won't let me past this
verification screen

 That way you have the information each time you load the clip and

 that when a user changes their user name, you need to update a bunch

[appengine-java] The title of email displays wrongly in localization

[Tony]

Hello,

I have a problem to dispay the title of email if it includes Chinese.
I tried:
[1]
...
String title = 测试标题;
message.setSubject(title);
...
And
[2]
...
String title = 测试标题;
title = MimeUtility.encodeText(title);
message.setSubject(title);
...

Both titles are displayed as ?. If the program works in
Tomcat (without GAE/GWT), the 2nd is ok.

Please let me know, if you have any idea to handle the title
localization issue?

Thanks in advance,
Tony

Thanks for the reply...

VAADIN does maintain its sessions, and clears them down if requested
to. Examining the data contained within ah_session using the
'Datastore Viewer', it seams to do a good job...

but, this doesn't explain the massive amount (in comparison) of data
in the 'Total Stored Data' quota.


I will file a report...

Tony.

 I'm not suggesting otherwise. But seeing that you don't get any
 answers/response here I think it would be next logical step. And even though
 I don't know VAADIN this looks like an inconsistency within the stats.
 BUT, keep in mind when reading the stats that there's some *delay* in the
 data. Maybe your framework cleans something somewhere meanwhile...?

  I have enabled sessions...the framework I am using, VAADIN, requires
  this.  But, arn't sessions stored in ah_session listed in the

 Yeah, like I said, I'm only curious. The entities surely would be listed
 there. Also they wouldn't delete themselves magically I guess. (So you would
 still have 100% space used.)

[appengine-java] One-to-many relationship

[Tony]

I've followed the GAE docs on setting up one-to-many relationship but
I'm still having trouble in retrieving the collection data back. I
have no problem getting the other non-collection properties back. Here
are my classes:

@PersistenceCapable
public class User{

@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;

@Persistent
private String uniqueId;

@Persistent
private String email;

@Persistent
private ListAddress addresses = new ArrayListAddress() ;
...
}

@PersistenceCapable
public class Phone{

@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;

@Persistent
private String number;
...
}

public class UserDaoImpl implements UserDao {


public void insertUser(User user) {
if(user.getKey() == null) {
com.google.appengine.api.datastore.Key key =
KeyFactory.createKey(User.class.getSimpleName(), user.getEmail());
user.setKey(key);
}
PersistenceManager pm =
PersistenceManagerWrapper.getPersistenceManager();
notNull(user);
try {
pm.makePersistent(user);
} finally {
pm.close();
}
}

@SuppressWarnings(unchecked)
public User getUser(String uniqueId) {
PersistenceManager pm =
PersistenceManagerWrapper.getPersistenceManager();
Query query = pm.newQuery(User.class);
query.setFilter(uniqueId == uniqueIdParam);
query.declareParameters(String uniqueIdParam);
User user = null;
try {
ListUser users = (ListUser)(query.execute(uniqueId));
//TODO abstract this
if(users.size()  0)
user = users.get(0);
} finally {
pm.close();
}
return user;
}
}

public class UserDaoImplTest {
 @Test
public void getUserTest() {
User user = createTestUser();
assertNotNull(The user object should not be null, user);
userDao.insertUser(user);

User returnedUser = userDao.getUser(TEST_USER_ID);
assertNotNull(The returnedUser object should not be null,
returnedUser);
Assert.assertPropertyEqualsExcludeProperties(User Object,
user, returnedUser, );

}
}

When I run the test, all the properties for User is populated but the
list of Phone if I get is empty.

[google-appengine] Problems with email from App Engine.

[Tony Of The Woods]

I set up a simple app that emails comments submitted on the site to
myself.

Firstly it's not completely clear from the docs what constitutes a
legal sender for an email.  Is it all of the following? :
(a) a registered developer of the application
(b) any legal receive address for the app, eg:
exam...@myappid.appspotmail.com
(c) the gmail address of any user logged in through the google login
service

No matter what I put in there I cannot successfully send any mail to
myself.  My mails do show up in the items sent count on the quota page
but they never get delivered.  I notice elsewhere that that have been
problems delivering to hotmail.  My email address is on one of the
mail.com domains.  Is it possible there is a glitch getting to
mail.com - or perhaps a blacklisting misunderstanding?

If I can send from exam...@myappid.appspotmail.com then I guess I
could put in a receiver process so I could see the bounced headers.
Is that the most sensible way of going about things?  Or maybe just
associate a gmail account with the app?

[google-appengine] Re: https://peek-a-boo.appspot.com/

[Tony Jackson]

I notice a lot of google app websites are proxy servers, and what I
think people can do is basically submit a url with the proxy server in
front of it to google and google will index it but it will also allow
you take down a competitor's website with this method, perhaps this is
an issue that the google apps department might look into? because once
google indexes the website with the google app proxy server in front
of it, the website will not longer be accessible to the google
visitors because it will produce a 503 error.

[google-appengine] Using ClientLogin: HOSTED vs GOOGLE

[tony]

There are lots of postings about how to use ClientLogin to
programmatically authenticate with a Google App Engine app. For the
account type, they all recommend using HOSTED_OR_GOOGLE. This is
wrong, and I will explain why.

There are two kinds of accounts in the Google world. The ones you
create for GMail, etc are Google accounts. The ones you create for
Apps for Domains are Hosted accounts. You can use a Hosted Account
email to make a Google Account, thus creating an email address that is
associated with both kinds of accounts.

Your Google App Engine app can be configured to work with (1) Google
Accounts or (2) Hosted Accounts for a particular domain.

Assume that we are developing an app for Google Accounts. A user
enters in an email address that is associated with a Google Account
and a Hosted Account. Google will use their Google Account for the
login. This all works fine.

Now, if we use ClientLogin with this same email address and use
HOSTED_OR_GOOGLE for the account type, login will be successful, but
it will use the Hosted Account, since the Hosted Account takes
precedence. As I mentioned above, you cannot use a Hosted Account for
an app that expects a Google Account. So the authentication will not
work.

So, when using ClientLogin to authenticate with a Google App Engine
app, you need to use GOOGLE for the account type if the app is for
Google Accounts, or HOSTED for the account type if the app is for a
domain.

I do have the same Problem (Ubuntu 9.10, Eclipse Galileo, Google

I found out that it helps, when i delete the contents of the web-inf/

 Hi,


 What is the name of your project, and the name of your App Engine SDK? I'm
 trying to decipher (in our code) where the message Updating
 myproject/...ne - 1.3.0 comes from.


 When Eclipse starts up, the SDKs will automatically copy over the necessary
 jars to your project's war/WEB-INF/lib folder. I think that's what is
 happening here. This should not cause a freeze-up in the IDE though.


 Is your war/WEB-INF/lib folder version-controlled, and are you using some
 sort of version-control plugin in Eclipse? If so, does it help if you remove
 the war/WEB-INF/lib folder from version control?

  That was a hint in the right direction, I think. I have disabled the

  In my opinion this is not a very elegant solution, but it works for me
  so far.

I think the key here is: ...for the sole purpose of enabling Google

In other words, Google may reproduce/distribute your content

Service.  If they did not have this right, there would be no way for
your users to access your data, as it is all stored on servers that
you do not own.

I am not a lawyer, and I don't work for Google, so I'm not saying your

they're covering all their bases.

can terminate this agreement at any time by ceasing use of the
service.

However, you make a good point - what if an App Engine app becomes the
next Facebook/Myspace/Twitter?  Could Google use these terms
nefariously?  Probably, and so maybe some clarification would be
helpful, but I don't think there's much cause for alarm.

 you give us access and rights over your code

 What about the people who are paying for the service? they are not
 allowed to keep their software proprietary either?

 Would that clause be valid if, for example, you have a very successful
 site/application that could raise the interest of google to buy it and
 you don't want to sell at their price? This clause is so more
 interesting because, probably 95% of the people who develop
 applications for GAE think and hope those will need to be very
 scalable - so, very successful - and between learning all the things
 related to scalability in their native language they rather
 Python/Java and program under some restrictions.

 So, is it possible that we want our applications to be so successful
 to force google to bring that clause into discussion?

[google-appengine] Re: Eating one's own dog food

[Tony]

Though I realize this is not exactly what you're asking, the concept
of GAE is that it exposes some of the infrastructure that all Google
applications rely on (i.e. Datastore) for others to use.  So, in a
sense, Google's various applications were using App Engine before App
Engine existed.  As far as I know, every Google service runs on the
same homogeneous infrastructure, which is part of what makes it so
reliable (and why the only available languages are Python and Java,
languages used internally at Google).

But I don't work there, so maybe I'm completely off-base.

 Google products and infrastructure and what are the schedules

 Is the GAE group supporting the Google Docs group as they

 Will those groups have to live under the same quota restrictions
 while they evaluate using GAE?  If not, why not? If they
 are unreasonable for an internal evaluation, what makes them

 Evaluating whether or not GAE should be used for a particular
 application is not FREE even if one gets a very small slice
 of GAE resources with which to do the evaluation.
 Tens or hundreds of hours go into determine if GAE has

[google-appengine] Re: Move sub-app to new appspot instance?

[Tony]

Ultimately the question the TOS is asking is: are multiple appspot
apps being used to circumvent quotas/limits?

It would seem to me that a facebook-clone app like you describe would
see considerable savings by splitting into multiple apps (because of
the free quota allotted to each app), which I imaging Google would
frown upon.  However, if your subapp has different requirements that
might justify it being moved to a new app id (for example, a different
group of developers who shouldn't have access to the main app's
dashboard, etc), you might get some leniency.

 Previous discussion considered unconclusively if a Facebook-clone
 where various services (i.e. images, messaging, walls, etc.) are split

[google-appengine] Re: Webservice authentication (Python)

[Tony]

The response has the Set-cookie header set, which will cause the
user's browser to save the cookie and then present it on the next
request (after redirected by the 302).  In my code I've opted not to
follow the redirect, and extracted the cookie myself, because it's the
urlfetch service doing the request, not the user.  You can then either
return a response to the user with a Set-cookie HTTP header (causing
their browser to save the cookie), or handle it some other way (return
it in the body and set the cookie with Javascript, for example).

I think I misunderstood your original question, though, and you're
looking for something different.  You want to get an authorization
cookie and then use it to make repeated requests with urlfetch, not
with a browser?  If that's the case, you're going to want to capture
the Set-cookie header from the second response, and supply that in
future requests (setting the Cookie header for urlfetch).

Basically, urlfetch will follow redirects but it won't handle cookies
automatically - so what's happening is it's ignoring the Set-cookie
header and following the redirect, and being denied because it's not
supplying a cookie.

 Yes, that is exactly what I want :) My client app. is not browser-
 based. I guess I'll just use your method then.. appengine_rpc must be
 intended for browser apps only, as it does nothing to capture the
 auth. cookie. I could of course extend the appengine_rpc module to
 capture the cookie, but the module uses urllib2.OpenerDirector.open()
 to open URLs and this is perhaps not the way to go in my case? I am
 not sure what the difference is between urlfetch() and open() it
 seems like I can get the headers (and hereby the cookie) by using info
 () on the response from open().

the sense that the 31st request is dropped, rather it's queued, but
yes it's unfortunate.

 2) Great to see that Service for storing and serving large files is

 Any indications on new max size would be great.

 3) Along those lines, has anyone implemented something like multi-blob

[google-appengine] Re: Querying for N random records on Appengine datastore

[Tony]

If the number of entities in the kind is reasonably small, you could
do:

keys = Kind.all(keys_only=True).fetch(MAX_ENTITIES)

Pick x keys out of that list, and then use db.get() to fetch them.

Otherwise, johnP's suggestion is probably best, but I don't see why
you need the extra overhead of pickling/unpickling the list.  Just
store the keys in a ListProperty(indexed=False).

 Darn you for publishing my good idea first! :)

 It doesn't bring the number of queries down to 1, but it does bring
 them down to 2, at least on the request side.

 Of course, it also means one extra transactions every time a new
 entity is created, so I don't know if there's any net savings, but
 this does seem like a reasonable way to address the issue at hand.

  A possibility is to maintain an index, which is a pickled list of
  entity keys, stored as a blob somewhere.  You'll need to maintain the

[google-appengine] Re: how to fast delete a complete datastore, please

[Tony]

There is no such option, but something that will speed up your deletes
significantly is to do a keys_only query.  The query you are currently
using fetches all 300 entities into memory (including their
properties, etc) - but you only need the key to delete the entity.
Try something like query = Homedata.all(keys_only=True) and you
should be able to delete more entities per batch for less cpu.
However, it's still going to be a long and cpu-intensive operation for
25000+ entities.

[google-appengine] Re: Reading the app.yaml version string from python?

[Tony]

You can access the global environment variable CURRENT_VERSION_ID -
from the docs:

CURRENT_VERSION_ID: The major and minor version of the currently
running application, as X.Y. The major version number (X) is
specified in the app's app.yaml file. The minor version number (Y)
is set automatically when each version of the app is uploaded to App
Engine. On the development web server, the minor version is always
1.

I believe memcache and datastore are shared across all versions of the
app, so keep that in mind.

I have not used this particular plugin but this might point you in the

ignores files that start with . (dot) when committing changes (since
it stores data in .svn folders).  You can either:

a.) commit the Eclipse dot-files and do import an existing project
on your second workspace
b.) don't commit the dot-files, and create a new project on your
second workspace (and use the repository checkout as the initial
directory)

That should work, if I understand your question right.

class User(db.Model):

  matchesAttempted = db.ListProperty(db.Key)

class Match(db.Model)
  interesting_property = db.StringProperty()

The properties on User contain db.Keys of Match entities that the User
relates to.  When you want to get all matches for a user, you just
merge the two properties into one list of keys and db.get
(list_of_keys).  No queries, even.

 What I want is when user 1 goes to this section of the app, to get a

 done in the sql sense using a logical OR, since that's not supported
 in the datastore since it doesn't perform well.

 Of course I can do two queries and join the dataset, but this
 introduces some serious pain in the workaround regarding paging on a
 large dataset.  Not to mention two queries per request just sounds
 slow/wrong.

 I watched the excellent video from google IO 2009 that instructs us to
 think of these things as group membership queries, and to do venn
 diagram self joins.

 So I was thinking the solution may be to remodel the entities like so:

 - Remove the Matches entity completely
 - change the Users entity to this:

 Users:
 -
 Listint initiatingUserIds
 ListInt attemptingUserIds

 I'm struggling to write the query that would then retrieve this data.

 Anyone have any ideas on this design?

[google-appengine] Re: Task Queue API Users

[Tony]

I think (correct me if I'm wrong) that what Colin is saying is that if
User A is logged in, and performs an action on a page which enqueues a
task, and the task hits a webhook, the webhook should be able to
operate just as if User A had logged in, and hit the webhook url (so
users.get_current_user() should return the user that enqueued the
task).

The workaround seems pretty easy, though, just pass the required
information in the payload: if user is None: user = db.get(request.get
('userkey')), or if user is None: username = db.get(request.get
('username')) or what have you.

Or maybe he's just saying you should be able to assign more granular
permissions like:

- url: /hook
  login: [admin, cron]

Or maybe I'm missing his point entirely :P

 Hi Nick,

  I'm not sure I see the problem - what user would you expect to see listed

 The problem is that the handler code needs to have an understanding of
 the particular calling client.  This tightly couples the handler code
 to the calling mechanism.  I totally wrecks the idea that the protocol
 should allow loose coupling of the two end points.  From my
 perspective, that's bad architecture.  If I explicitly say I need a
 user (admin or otherwise) to access a URI, then the system should make
 sure that URI is not accessed unless there is a user.  Once you start
 introducing edge cases - 'It's true unless this, or unless that', the
 platform becomes 'clunky'. app.yml is an interface contract, and
 currently asynch breaks that contract. That contract is far more
 important than one client's (GAE system) difficulty (which user?)
 conforming to it.  My 2c anyway.  Thanks,

  an admin access, but because there's no current user.

   I'm guessing that
   the goal of theTaskQueueAPI is to be usable on generic URLs - e.g.
   in a RESTful application, the full CRUD (and more) functionality is
   exposed via a dynamic set of URL's that more than likely are not
   specifically for theTaskQueueAPI - however the above situation
   means you really have to code explicitly for theTaskQueueAPI,
   because the meaning of the directives in app.yaml is not reliable.  It
   looks like cron functionality works like this as well, and that has
   been around for a while.  Use cases such as write-behind outlined in
   Brett's IO talk are significantly limited by being unable to predict
   whether you will get a user or not (especially if you intend to hit
   RESTful URI that could just as easily be hit by real users).  Sure,
   there are ways to code around it, but it's not pretty.

  I'm not sure I see the problem - what user would you expect to see listed
  when a webhook is being called by the cron ortaskqueuesystem?

   I'm keen to understand how google sees this situation, and whether the
   current situation is here to stay, or something short term to deliver
   the functionality early.  Cheers,

[google-appengine] Re: newbie question: Alternatives of auto_increment

[Tony]

It depends on what exactly you need it for.  If you need it for the
total count, you can use the count() method on queries (slow) or
maintain a counter on another entity (good), or on a collection of
entity shards (better).  If you want to know how many entities of a
kind you've created ever (even if some are deleted), you can use the
key_name property to implement your own auto_increment policy.
Something like this (mind you this code is probably terrible :P):

class Counter(db.Model):
  count = db.IntegerProperty()

class Item(db.Model):
  some_prop = db.StringProperty()
  created_at = db.DateTimeProperty(auto_now_add=True)

  @classmethod
  def new_item(cls):
counter = Counter.get_by_key_name(item_counter)
count = counter.count
counter.count += 1
counter.put()

## or, something like this, which wouldn't require you to maintain
a counter (but requires a query)
count = Item.all(keys_only=True).order(-created_at).get().name
().split(_)[1]

return cls(key_name=num_+str(count+1))

 Hi,
 I am new in google app engine.

 I am a PHP-MySql developer. I used auto increment (integer type)
 always in my database. It helps for total count, works as primary key
 and so on. But as I can see auto_increment is not available for Data
 Store. I was wondering what is the alternative idea that Data Store
 provides and recommend us to use?

 Thanks in advance.

[google-appengine] Re: Shifting applications between google and google apps.

[Tony]

As of now, there is no way to change your authentication setting from
Google Accounts to Google Apps-only, or vice versa, and you can't
delete an application or otherwise re-use the name.  It sucks, I'm
currently in the same situation as you.

 Hi there,

 I got a small problem that I need to sort out with Google App Engine.

 When I first signed up to develop for GAE I used my regular Google
 account and dutifully registered  the name of a product my company is
 developing.

 I've realized that I should have signed up using my companies Google
 Apps account instead.

 So at the moment I've got a registered application under my regular
 Google account that I need to move across to my companies Google
 Apps account.

 What should I do? Can I delete the registered application from within
 my account and then add it to my apps domain? Will that work?

 I don't want to lose the registered application name as it's very
 important to us.

 I've also read that there is some work in progress sort out issues
 like this. Is that something I should wait for instead?

 I'd really appreciate an answer for this as it's potentially holding
 back our application deployment.

 Thanks for your time.
 Matt

[google-appengine] Re: Does cron jobs take more time to init than normal handlers

[Tony]

I'm pretty sure the cron service simply calls a url and reports
whether it got status code 200 or not.  Other than that, there
shouldn't be much difference.  You should try profiling two requests,
one from cron and one from a browser, and comparing them to see what
the real difference is.

 Hello,

 Now that I got cron, I moved something I used to do in a normal
 handler to use a cache and refresh every 5 minutes.

 What I discovered now is that what used to take 400ms in the normal
 handler is now taking 800+ms in the cron handler. (I do the exact same
 thing, really)

 I don't know if cron handlers are being cached or since I do it not
 very frequently I have to pay that price.

 Thanks

[google-appengine] Re: Best way to get support for Google App Engine issues

[Tony]

http://code.google.com/p/googleappengine/issues/list

This is about your only other option, though of course it doesn't
solve the privacy issue or ensure timeliness.  The lack of an
individual trouble ticket system like you describe is unusual for a
paid service.  Fortunately the Google folks on this group are quite
responsive and helpful, but like you say, there's only so much they
can do.

 I have been using the GAE for about a year now. On the positive side,
 I had very few problems. Pretty much everything works as described in
 the documentation.

 As far as I can remember, I had three incidents where I needed support
 from Google. At the end all my issues were resolved by the great
 Google folks who monitor the group BUT not in a very timely manner.

 In the first incident, my problem was resolved in a couple of days. In
 the other two incidents it took 5-8 days. In the most recent case,
 that took 8 days we lost valuable time because of the following
 reasons:

 1) The Google Engineer who first handled my case what in an overseas
 timezone (Nick is in Ireland, I am in California) and the latency of
 requests responses was 24 hours
 2) Since I did not want to reveal information about my site in a
 public forum I sent it through private e-mail that was classified as
 spam
 3) Another user who had nothing to do with me intervened to the thread
 with his issues and confused the situation

 So I am wondering,

 1. Is there a better way to get support? You know some application
 (proably part of the dashboard) where you file a ticket, you describe
 the issue and its priority  and you get back a ticket number,  you
 have an option to keep it private between Google and you etc? In GAE
 spirit develpers could even get a few tickets free per month and then
 pay if they go over their ticket quotas :-)
 2. If not, s something like that or even better than that in the
 plans?
 3. In the meantime, I described what I did to get support, should I
 have done something in a different way?

 Thanks

 PS: In all three issuesthe problem was around indexes problems. There
 seems to be a bug where if some index quota is exceeded the indexes
 get in some weird state and Google personnel has to intervene.
