Re: [google-appengine] Re: Quota on number of entity types / kinds?
You could get the dev server to update index.yaml with the dynamic indexes by running a query on the dev Datastore that would require the desired index on your dynamic entity kind. However if it's not possible to know all the dynamic entity kinds you'll need on the live server, then this wouldn't work. What about creating a base PolyModel class, and have all your dynamic entity kinds inherit from that? 2010/1/9 RyanD > Hmm, nevermind, I see the issue in the issue tracker related to an > "Index Management API".

[google-appengine] torrent-server : store and serve really big files using BitTorrent
I wanted to learn more about App Engine and the BitTorrent protocols, and I figured the best way to learn is by doing. So I've created 'torrent-server'; it lets you: Upload arbitrarily large files into the App Engine datastore (using a command-line python client and the App Engine remote_api, splitting them up into pieces smaller than the maximum datastore BLOB size). Download them using a BitTorrent client that supports the BitTorrent "webseed" protocols (you can also download directly via HTTP if the file is smaller than the 10MB App Engine response limit). Downloading large, popular files this way will save you bandwidth costs, because the BitTorrent clients will try to get the file from each other first, and only use your server if they can't find other clients that have (or are downloading) pieces of the file. I also incorporated Allen Porter's "open-tracker" code, so torrent- server acts as a self-contained BitTorrent serving and tracking solution.

One followup question to the case described above: If I want entity types that are application controlled, and dynamically created through the low level API (as described above), then there is no way to create indexes unless there is also some kind of low level API for index creation. As it stands the index files appear to be a static part of the uploaded application files, which wouldn't work with dynamically create entity types.

[google-appengine] GWT RPC + JDO - persisted object loses its id when sending from server back to client.
I have a problem with the following things:
@PersistenceCapable(detachable = "false", identityType =
IdentityType.APPLICATION)
@Inheritance(strategy = InheritanceStrategy.SUBCLASS_TABLE)
public abstract class Person {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName = "datanucleus", key = "gae.encoded-pk",
value
= "true")
protected String id; //encoded string
}
public class Employee extends Person{
... // some persistent attributes
}
public class EmployeeDaoImpl extends RemoteServiceServlet implements
EmployeeDao {
/**
* Persists one employee obj
*/
public Employee create(Employee entry) {
PersistenceManager pm = PMF.get().getPersistenceManager
();
try {
pm.makePersistent(entry);
}
finally {
pm.close();
}
return entry;
}
}
//THE CALL
public Request daoCreate(Employee entry) {
AsyncCallback callback = new
AsyncCallback() {
public void onFailure(Throwable caught) {
}
public void onSuccess(Employee result) {
Window.alert(result.getId()); //
<-- RETURNS NULL???
...
}
};
return dao.create(entry, callback);
}
Okay, when debugging this, the debugger tells me that , at the 'return
entry' line, it has a generated id. So I know that on the server it
gets an ID. but when it comes back the id is null again!
I used detached=false, because of this serialization issue, but that's
not a problem. I also tried copying the object I return attribute-by-
attribute, but it also ended up with an id being reset as soon as the
onSucces() is called (so it doesn't even fail).
Any ideas?
Oh lastly, i got another object, which is not part of a inheritance,
eg.
public class Hobby {
String id;
}
Storing this in a similar function works fine!
I've run into a wall here, is it a GWT bug? Or am I missing something?

[google-appengine] Key sorting.
Hi. I am writing a cms, which has sections and articles. Both of them are represented by the same object of the type Node of my own composition. Among other fields, a node has a Set, representing it's children. Consequently, root nodes (i.e. sections have simple keys (say, Node(1))), and articles have composite keys (say, Node(1)/Node(2)). And for the first page of my cms i would like to have a number of articles disregard of the sections they are in. In order to do that i need to sort the articles by their keys. However, in that sorted list they appear in the wrong chronological order because of the "first part" of their keys. I.e., apparently Node(1)/Node(7) will come earlier than Node(2)/Node(3). Is there a way to sort the entities in a query by the last part of their keys? -- Best Regards, Timofey Danshin. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

Re: [google-appengine] Performance Issues
can you send us your application ID? we can help take a look at it. also, how was performance yesterday,... and today? just curious if there were any differences, or whether something else changed, like usage, latency, datastore access, etc. thx! -wesley On Mon, Jan 4, 2010 at 8:06 PM, Devel63 wrote: > I've been very concerned about cold-start performance, since I have a > low traffic site (www.lifehints.com). > > Over the past few days, though, performance has been great!!

Re: [google-appengine] Application specific configuration vars
devraj, since it's your application, it's probably best that you maintain your own configuration files because those are specific application settings that you're adjusting, not App Engine settings. plus Python's syntax is so straight forward that i've seen many companies simply use a separate .py consisting of one or more dictionaries which works just fine as a config file. if you want a more "traditional" style configuration file format, the Python has the ConfigParser module: http://docs.python.org/library/configparser.html finally, i can't believe i'm saying this but, you don't want to be too tied down or become dependent on App Engine. perhaps at some point, your app will be so wildly successful that you need to run your app on a different platform. if you keep it as pure Python, you can take it anywhere you have Python execution ability, not just App Engine. best regards, -wesley On Mon, Jan 4, 2010 at 6:30 PM, Devraj Mukherjee wrote: > Hi all, > > My AppEngine application is written in Python.

in case it wasn't clear or seems to be obfuscated, here's a plain text
example of what the above does:
>>> a = ['foo', 'bar', 'google', 'app', 'engine']
>>> a
['foo', 'bar', 'google', 'app', 'engine']
>>>
>>> ''.join('msg %d: %s; ' % x for x in enumerate(a))
'msg 0: foo; msg 1: bar; msg 2: google; msg 3: app; msg 4: engine; '
here's a more Python-newbie-friendlier alternative:
>>> ':'.join(a)
'foo:bar:google:app:engine'
the point is that it is not a string, and you should use the str.join
() method to merge them together into a single string so that you can
successfully make the call to log it.
cheers,
