If this is not good, it might have to change the model.

[appengine-java] Question about request from one app to another one through ajax
I created two apps, one app provides a restful web service( such as abc001.appspot.com), and I want to make use of that web service in another app page (such as abc002,appspot.com) through ajax. Through setting the [ document.domain = appspot.com; ] in javascript, the browser could allow the ajax request from abc002 to abc001, but the request finally failed, from the log of abc001, I got the following message: java.security.AccessControlException: access denied (java.lang.RuntimePermission accessDeclaredMembers) at java.security.AccessControlContext.checkPermission (AccessControlContext.java:355) at java.security.AccessController.checkPermission (AccessController.java:567) at java.lang.SecurityManager.checkPermission(Unknown Source) at com.google.apphosting.runtime.security.CustomSecurityManager.checkPermission (CustomSecurityManager.java:45) ...

Local Task Queue are running tasks as fast as they can an not honouring the maximum rate for the queue. on a 0.5/s queue I'm seeing 80+ tasks handled in a matter of seconds. This is a problem for me because I am using the URLFetch service to fetch content that I am not supposed to request more than once every 2 seconds. I'd like to at least see the local queues honouring the maximum rate, but it would be really useful to be able to pause the queues and have the old method of manually triggering tasks in the queue to be processed.

[appengine-java] java.lang.RuntimeException: Unable to replace JPACallbackHandler - Unit Testing
Hi All,
I am trying to write a bunch of tests with JUNIT for my JDO classes.
The package works when integrated in a appengine web application, but
I get a RunTimeException when testing in a Junit 'environment'.
I started with the JDODataSourceConfigTest source file in the
appengine test directory.
and It's ok with nothing included.
Then I tried to store some data within the two methods implemented:
public void testTransactionalPMF() {
JDOPersistenceManagerFactory pmf = (JDOPersistenceManagerFactory)
JDOHelper
.getPersistenceManagerFactory(transactional);
DatastoreManager storeMgr = (DatastoreManager) pmf.getStoreManager
();
JDOPersistenceManager pm = (JDOPersistenceManager)
pmf.getPersistenceManager();
// assertTrue(storeMgr.connectionFactoryIsTransactional());
DomainGAE domain = new DomainGAE(Name, Description);
Transaction tx = pm.currentTransaction();
try {
tx.begin();
pm.makePersistent(domain);
tx.commit();
} catch (Exception e) {
System.out.println(Exception e: + e);
e.printStackTrace();
if (tx != null) {
tx.rollback();
}
}
pm.close();
pmf.close();
}
---
DomainGAE is a simple Class
import javax.jdo.annotations.IdGeneratorStrategy;
import javax.jdo.annotations.PersistenceCapable;
import javax.jdo.annotations.Persistent;
import javax.jdo.annotations.PrimaryKey;
import com.google.appengine.api.datastore.Key;
import com.google.appengine.api.datastore.KeyFactory;
import
@PersistenceCapable(table = domain, detachable = true)
public class DomainGAE implements Domain {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
protected String name = null;
protected String description = null;
public DomainGAE(String name, String description) {
this.name = name;
this.description = description;
}
.
}
Here is the error and the stackTrace:

If you're running IntelliJ IDEA with the Google App Engine plugin, it should have been imported.

It lives in APP_ENGINE_SDK_ROOT/lib/shared/geronimo-servlet_2.5_spec-1.2.jar If you're not using Eclipse, you can read our Ant documentationhttp://code.google.com/appengine/docs/java/tools/ant.htmlto get an idea of what jars you should be compiling against, and which jars you should be deploying with your webapp. Intellij also has a Google App Engine plugin, which should help out with this.

What are you doing in RoleFilter? Is it something that would use this

When deploying an App Engine application, you will need to place required
external libraries under WEB-INF/lib so that they are also deployed
correctly. The reverse of this is also true: you will need to add JAR files
under WEB-INF/lib to your classpath when you run the development server.

Re: [appengine-java] error xerces not found when run as web app
I'm not able to reproduce this, though I am using 2.9.1. Were you able to
figure this out? You may need to tell your IDE to treat WEB-INF/lib as part
of your classpath, since putting it in this library just makes sure it is in
the classpath when deployed and not necessarily locally when you are running
the development server.

It used to work fine earlier but now I get the following: Traceback (most recent call last): File /base/python_lib/versions/1/google/appengine/ext/webapp/ __init__.py, line 507, in __call__ handler.get(*groups) File /base/data/home/apps/fanvenues1/1.338340892144330219/main.py, line 105, in get currenthits = section.layout.hits File /base/python_lib/versions/1/google/appengine/ext/db/ __init__.py, line 2907, in __get__ instance = get(reference_id) File /base/python_lib/versions/1/google/appengine/ext/db/ __init__.py, line 1182, in get entities = datastore.Get(keys) File /base/python_lib/versions/1/google/appengine/api/ datastore.py, line 257, in Get raise _ToDatastoreError(err) Timeout Why is this happening when I actually have a paid account?

[google-appengine] Datastore contention
After reading these two articles: Avoiding datastore contention: http://code.google.com/appengine/articles/scaling/contention.html Sharding counters: http://code.google.com/appengine/articles/sharding_counters.html I'm a little confused at to what causes datastore contention, and how to design around this. The Avoiding datastore contention article states that datastore contention occurs when a single entity or entity group is updated too rapidly. Yet the Sharding counters article seems to suggest that you can rapidly update entities of the same kind (and hence entity group), as long as they have different key names. Which it is? For example, if I am expecting 100 comments/second to an article I've written (let's assume I'm a really good writer), and the Comment class is its own entity group, can I safely put() all comments into the datastore as they arrive using this Comment class, or am I better off sharding them into separate classes (eg. Comment1, Comment2, ..., CommentN) so that the comments are distributed across N entity groups? -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] Datastore contention
An entity group is a group of objects, not classes. If Article#1237 and its comments are in a single entity group, then yes you'll have trouble with more 100 comments per second. Simple solution: Don't put the comments in the article's entity group.

[google-appengine] this URI uses a high amount of cpu and may soon exceed its quota
In the dashboard, there is a yellow triangle shown on the right side of the Avg CPU column on the line of a URI.

Of late, I have seen it repeatedly/regularly happening within several seconds. This is something we monitor fairly closely. The average lifetime of an idle VM varies as the load across App Engine varies, but they do not timeout within several seconds. One thing you might be seeing is that a burst of several requests can cause more than one VM to be loaded simultaneously. I've avoided (so far) the auto-ping approach; your idea to auto-ping only when a user is on a page is intriguing. Still wasteful and wrong, but perhaps necessary. Sending a single ping a few seconds ahead of time for a user is very low waste. Yes, I have voted for the paid warm instance :-) Finally, I don't understand how I can significantly reduce my warm up time. I suppose I could split each page into a separate app.yaml handler (already done for admin versus user tasks), but then the user would even more certainly run into startup issues when navigating within the site. Besides, most of the time is spent importing Django and system stuff I can't control. You can control whether or not you use Django. I also don't understand how splitting your app into separate handlers would cause more startup issues for you. The only reason I'm using Dango (0.96) is for translations ... is there a built-in way to handle translations via webapp? Sorry, I'm not that familiar with what's available for Python, but my understanding is that Django is aggressive about up front initialization.

This is not what we're seeing. Are you sure you aren't seeing loading requests to several different VMs in parallel? also: to write a Hello World python app that responds from a cold start on the order of 100m - again, I have not seen this in practice for quite some time. the simplest of python sites, with no imports and very little code seem to start in the 500ms to 1s range (and sometimes, much longer). Please note Nick's post here, where he changed his original cold-start metrics: http://bit.ly/6Fsoxv Nick's example is not Hello World. He's cold-starting his blogging app in less than 500ms. (I personally believe that is quite acceptably responsive). What I'm driving at is that there's a minimum startup time which you can not control as a developer, and that startup time is very low for python (on the order of 100ms). Everything else is under your control: What dependencies you have, what web framework you use, whether you push static content and use ajax requests, etc... I'm now under the impression that slow VM startups is a GAE issue and while user imports are critical to keep them reasonable once they are started, there is a lot of overhead that is completely out of our control. The only way I've found to keep low traffic sites bearable is to use polling from the task queue, so IMO, the title of this post is quite appropriate cheers brian On Dec 9, 12:26 pm, Toby Reyelts to...@google.com wrote: Responses inline.

[google-appengine] Re: Staying authenticated
Thanks for your reply Ikai,
I understand what you're saying - my question is that i'm trying to
allow a user who is logged into their google doc speadsheet and use
=ImportData(http://app.myapp.com/Service/value;) in a cell to pull
in data from an app engine service. This works just fine - i was
hoping that
since the user logged into the app engine app and then logged into the
google doc that the authentication cookie they got for that session
would somehow get passed along in the header of data request. It
seems like, having logged into both places, the browser session stays
authenticated to both places, but the importdata request doesn't
provide the header.
It makes sense that this dosn't work - but just in case there is a way
to do this - here is the scenario. Say http://app.myapp.com/Service/value
is a rest service that calls a function that returns true or false if
the user is logged in
1. user logs into the app engine app.myapp.com
2. user navigates to their google docs and logs into that.
3. user navigates to http://app.myapp.com/Service/value - returns true
4. user navigates back to spreadsheet and puts this value in a cell
ImportData(http://app.myapp.com/Service/value;)
5. returns false.
just seems like the authentication cookie isn't available from the doc

If I understand you correctly, what you are seeing is that a user that logs
into your application will have to log in again for Google Docs. This sounds
like expected behavior. A user may wish to log in to an application without
logging into their docs account. Logging into an App Engine application with
a Google login does not log a user into any Google services automatically.

the way i see it, they are logged in to the point where they can work
with the app engine app and open their google docs, why would the user

So you're logged in and can run the app, open your google docs, past

Re: [google-appengine] Model attribute help
You could add a StringListProperty called tags to the content model. Or, when you create a new Tag you could make a Content model its parent. So, class Content(db.Model): content = db.TextProperty() tags = StringListProperty() or, class Content(db.Model): content = db.TextProperty() class Tags(db.Model): tags = StringListProperty() content = Content(content=Some content) content.put() tags = Tags(tags=['tag1','tag2','tag3'], parent=content) tags.put() There are a number of other ways to handle tags as well. It just depends on your intended usage. If you search the list you will find some recent posts referencing a taggable mixin. I have not used it yet, but it looks interesting.

Re: [google-appengine] 2 memcache.incr questions
INCR is atomic. An application should not be connected to multiple memcache
servers because key sharding will cause certain keys to have an affinity for
certain instances of memcache.
Expiration works in Memcache lazily if items have not been evicted from the
cache in according with LRU (Least Recently Used): on a GET of a value, the
client checks the expiration to see if the item has expired or not. If so,
the value is not returned to the user and is explicitly expired. Incremented
values are stored in Memcache as Strings, so in your example, what *should*
happen is that an expiration is set such that when you do a GET, if the
value is past its expiration time, it will not return. Have you been seeing
different behavior in your testing?
On Thu, Dec 10, 2009 at 12:26 PM, N Panar infinityminusn...@gmail.comwrote:
memcache.incr() is supposed to increment a key transactionally, so
that two clients can't clobber each other ... but can the application
expect to be connected to ever be connected to more than one memcache
server that each have different values? (it is expected that is
possible that it will be connected to zero memcache servers).
Also, how does expiration interact with incr()? There isn't a time
flag for incr(), but what happens if I add the key with another call
rather than using the initial_value flag, like so:
memcache.add('rlcnt-%s-%s' % (op, ip_h), 0, time=60*90)
newcnt = memcache.incr('rlcnt-%s-%s' % (op, ip_h))

[google-appengine] Re: Tragedy of the Commons, and Cold Starts
Toby, Here's a site that gets almost no traffic (not yet publicized): www.lifehints.com Try it Monday morning at 9am PST and see how quickly it times out. I've been seeing it apparently time out in a few seconds during the workday. I suppose it's possible that what I'm seeing is Google firing up another instance, but that sounds unlikely given that there's no one else on the site most of the time. On a Friday evening (now), it's staying warm for quite some time.

This is not what we're seeing. Are you sure you aren't seeing loading requests to several different VMs in parallel? also: to write a Hello World python app that responds from a cold start on the order of 100m - again, I have not seen this in practice for quite some time. the simplest of python sites, with no imports and very little code seem to start in the 500ms to 1s range (and sometimes, much longer). Please note Nick's post here, where he changed his original cold-start metrics:http://bit.ly/6Fsoxv Nick's example is not Hello World. He's cold-starting his blogging app in less than 500ms. (I personally believe that is quite acceptably responsive). What I'm driving at is that there's a minimum startup time which you can not control as a developer, and that startup time is very low for python (on the order of 100ms). Everything else is under your control: What dependencies you have, what web framework you use, whether you push static content and use ajax requests, etc... I'm now under the impression that slow VM startups is a GAE issue and while user imports are critical to keep them reasonable once they are started, there is a lot of overhead that is completely out of our control. The only way I've found to keep low traffic sites bearable is to use polling from the task queue, so IMO, the title of this post is quite appropriate cheers brian On Dec 9, 12:26 pm, Toby Reyelts to...@google.com wrote: Responses inline. On Sun, Dec 6, 2009 at 7:49 PM, Devel63 danstic...@gmail.com wrote: Toby, you write that it doesn't usually pay to optimize loading requests. I agree with this whole-heartedly when you have your own server, and only load once per day or month. It's probably true using GAE when you have 100K+ page views per day. I think there's a misunderstanding here. What I said was that it's not worth optimizing loading requests in regards to quota. Latency is a separate concern. But for lower-volume web sites, GAE performance is atrocious. In my personal case, we have optimized in all sorts of ways (js minification, liberal use of memcache, image sprites, sticking with Django 0.96, etc.) ... but the typical user experience is quite poor. It takes 3-10 seconds for the first page to load, and then often the instance is swapped out while the user reads the current page, so that the next request experiences the same thing. If the app is warm, performance is fine. If your VM is timing out while a user is actively visiting the site, then your site is extremely low traffic. VM timeouts are measured on the order of minutes, not seconds. So, for example, that means that you didn't receive any traffic to your VM at all for several minutes between the time the user fetched the first and second pages. Maybe this gets appreciably better as traffic improves, but of course, I can't see that at present. Yes, as stated above, VMs are not aggressively collected. In the normal case, if you have an active user of your website, you shouldn't see a cold-start per request. Maybe in your particular case you can asynchronously ping your backend (for example, with an AJAX request) a few seconds before they continue onto the next page? I love GAE in theory, but it's getting harder to ignore the reality of low-volume performance. As stated above, I think you're falling into a particularly bad extreme (continuous cold requests for an active user). This might require some creativity (for example, as above) to work around. In terms of speeding up the loading request itself, the good news that the bulk of of that time is directly under your control. As an existence proof of this, you should be able to write a Hello World python app that responds from a cold start on the order of 100ms. This means you might try doing things like paring down the dependencies that you load on cold requests. You can also
