[appengine-java] [Perhaps OT] Oracle vs. Google : Java still a viable language?
Hi all, Some of you may consider this off-topic (apologies to those that think it is OT), but I think it's pertinent to generate this discussion: given Oracle's lawsuit against Google http://bit.ly/bMEL6A , is Java a viable programming language anymore? I think the threat of Oracle adversely affecting the Java community has just become more real. Motivation: I am at the early stages of implementing a web app on GAE using Java, but if I need to switch to Python, I shouldn't delay it any more. I understand that Java SE and EE are licensed differently from Java ME, nonetheless... Oracle's doesn't enjoy a very good reputation in the open source world, and I don't trust them, though up to this point it was just an intrinsic mistrust, without any firm reason behind it. Java development as a language has also been held up/very slow over the past few years. Oracle's stewardship only makes things more iffy (are those the correct spellings :-)?). What I like about Java SE: the fantastic tutorial (even today it can sometimes come in handy), javadoc, simplicity, no useless syntactic sugar (unlike everything designed by Microsoft). On the other hand, Java EE... is a morass... Anyway, what do you guys think? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

You'll have to do something like the following:
- Iterate over the new contact methods and persist them.
- Retrieve the Person object.
- Iterate over the newly persisted contact methods and add their keys
to the Person's list of contact methods
At the moment you're just trying to add objects to a filtered result
set of random contact methods, which doesn't make much sense :)

Hi,
the problem is this line:

Beware that the only way you should ever store a Second object is:
myFirstObject.getList().add(mySecondObject);
pm.makePersistent(myFirstObject);
since Second.owner is mapped it's automatically populated by the
persistance manager.
Hope this helps,

2) Does the check on null object (e.g. if (owner==null) owner = new

3) Does the assignment on definition of objects (e.g.

strange behavior?
4) Do I need to add any other annotation to owner field of Second

[appengine-java] Re: Best practice modeling a 1:n user-relationship with List properties
Hi,
my recommendation would be to use ListString . In your reasoning for
query 2 be aware of the lazy loading that JDO performs in the
background to retrieve the related objects.
Query one and two are similar (if nickname is a field of MyAppUser):
Query q = pm.newQuery(MyAppUser.class);
q.setFilter(userKey == userKeyParam);
q.declareParameters(String userKeyParam);
q.execute(appUserKey);
will give you a listMyAppUser of his friends.
Hope this helps,

I have two queries:
Query 1: I want to select all MyAppUsers where a specific User is in
the friendsList.
Query 2: I want to get all nicknames of the friends of a specific
MyAppUser. This can be achieved by getting a MyAppsUser by id and then
calling for each user user.getNickname().
Question query 1: Is a query with a filter on ListUser friendsList
faster or slower than a query with a filter on ListString
friendsList or is it equal?
For query 2 I would say that a ListUser friendsList is faster,
because I have direct access to the nicknames. With only the id stored
in the friendsList, I have to make another query for each friend in
the list to get his nickname.

Re: [appengine-java] [Perhaps OT] Oracle vs. Google : Java still a viable language?
Motivation: I am at the early stages of implementing a web app on GAE using Java, but if I need to switch to Python, I shouldn't delay it any more. Anyway, what do you guys think? IANAL but you asked so here goes. I think you are fine using java on GAE. My guess is that since appengine is a derivative of OpenJDK that the (SE) patent grant holds for appengine as long as it doesn't implement new core functionality which the OpenJDK does not. In such a case, I don't believe the patent grant holds. You'd have to read the grant more closely or an analysis of it to know whether only partially implementing it carries the grant. Even if Oracle were to argue partial implementation does not, I believe the GPL2 combined with a patent grant for that code means effectively that Oracle can not say what people do with the GPL2 code, only that new functionality may not carry the protection. So, were GAE to fork OpenJDK and implement new core java classes (this does not mean new classes using java but a re-implementation of java with new functionality), then it's possible that we may see patent issues. Given the issues with Android though, I suspect Google will stay in the clear and I do not believe the GAE SDK does this. That said, if you try to take the SDK jars and set up an equivalent of GAE that runs on your phone (note: I am not talking about an app on a phone that connects to GAE, I am talking about *running* a GAE instance on a mobile phone) then perhaps you may have trouble as Oracle reserved the rights to mobile devices for non-GPL versions of Java. Nobody would or could ever do that I think, and so am sure it won't ever be an issue. Don't listen to me though. Really don't.

[appengine-java] Re: Best practice modeling a 1:n user-relationship with List properties
Hi,
be aware of the lazy loading that JDO performs
Question 1: Do we have lazy loading on lists of Core Value Types like
Google account (com.google.appengine.api.users.User) too?
Question 2a:
If a myAppUser has for example 1000 friends. Then with ListString I
would have to read the referenced myAppUser's for each userId in the
list to get the nicknames. To get all nicknames in one query I would
have to put a where condition on the userId of each user and
concatenate the conditions with Or, ||. I read, that a query has a
limit of 30 Ors. So I would have to split the Query in 30-packages.
Is this a good solution or would it be better to hold the nicknames in
a separate denormalized list in myAppUser? (Problem with the
denormalized nickname-list would be, that I would have to update the
list each time a user changes his nickname)
Question 2b:
Would it be too much overhead to read the nicknames in a separate
Query for each userId? Or is this a bad solution because of the
datastore calling overhead?
Question 3:
Is it possible to put a query-filter on a subfield of a Google account
user object (for example the nickname-field)? In my tests I was not
successful...

Hi,
my recommendation would be to use ListString . In your reasoning for
query 2 be aware of the lazy loading that JDO performs in the
background to retrieve the related objects.
Query one and two are similar (if nickname is a field of MyAppUser):
Query q = pm.newQuery(MyAppUser.class);
q.setFilter(userKey == userKeyParam);
q.declareParameters(String userKeyParam);
q.execute(appUserKey);
will give you a listMyAppUser of his friends.
Hope this helps,

Hi all,
I am trying to model a 1:n relationship between different myAppUser
instances on Google App Engines Datastore. MyAppUser has a reference
to 0...n other users (friends).
MyAppUser is currently defined as showed below:
class MyAppUser {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName = datanucleus, key = gae.encoded-pk, value =
true)
private String primaryKey;
@Persistent
private User user
@Persistent
private ListUser friendsList; Or alternative private ListString
friendsList;
...
}
I have two queries:
Query 1: I want to select all MyAppUsers where a specific User is in
the friendsList.
Query 2: I want to get all nicknames of the friends of a specific
MyAppUser. This can be achieved by getting a MyAppsUser by id and then
calling for each user user.getNickname().
Question query 1: Is a query with a filter on ListUser friendsList
faster or slower than a query with a filter on ListString
friendsList or is it equal?
For query 2 I would say that a ListUser friendsList is faster,
because I have direct access to the nicknames. With only the id stored
in the friendsList, I have to make another query for each friend in
the list to get his nickname.

Thanks for sharing your thoughts Shawn. IANAL either :-). I am worried about not just Java on GAE (though that's the more immediate concern), but also about Java's future in general. Don't want to be stuck with a proprietary language that has bad stewardship and a belligerent, short-sighted, greedy corporate owner. Also, Java on GAE seems to be a secondary citizen to Python :-)... that makes me question even more whether I should be learning Python ;-).

Anyway, what do you guys think? IANAL but you asked so here goes. I think you are fine using java on GAE. My guess is that since appengine is a derivative of OpenJDK that the (SE) patent grant holds for appengine as long as it doesn't implement new core functionality which the OpenJDK does not. In such a case, I don't believe the patent grant holds. You'd have to read the grant more closely or an analysis of it to know whether only partially implementing it carries the grant. Even if Oracle were to argue partial implementation does not, I believe the GPL2 combined with a patent grant for that code means effectively that Oracle can not say what people do with the GPL2 code, only that new functionality may not carry the protection. So, were GAE to fork OpenJDK and implement new core java classes (this does not mean new classes using java but a re-implementation of java with new functionality), then it's possible that we may see patent issues. Given the issues with Android though, I suspect Google will stay in the clear and I do not believe the GAE SDK does this. That said, if you try to take the SDK jars and set up an equivalent of GAE that runs on your phone (note: I am not talking about an app on a phone that connects to GAE, I am talking about *running* a GAE instance on a mobile phone) then perhaps you may have trouble as Oracle reserved the rights to mobile devices for non-GPL versions of Java. Nobody would or could ever do that I think, and so am sure it won't ever be an issue. Don't listen to me though. Really don't.

Well, as long as Red Hat/JBoss stays what it is now, I think Java is safe. Red Hat has become an important member of the Java community since they acquired JBoss and they were (I think) one of the first contributors to OpenJDK. All the products of JBoss rely on Java, so if, at some point, Oracle tries to really close down Java, my guess is Red Hat will then fork OpenJDK. You could definitely argue that Red Hat is yet an other greedy corporate owner but it is one that has always understood the importance of openess.

[appengine-java] Re: JDO: Null parent on some children objects
Hi Frederik!
Sorry for my ignorance, I tougth that the right way to save a Second
object was:
pm.makePersistent(mySecondObject);
myFirstObject.getList().add(mySecondObject);
pm.makePersistent(myFirstObject);
while if I understood your explanation I don't have to invoke
pm.makePersistent() on mySeconObject, is it?
I also put in all my getter methods a check on null object, in that
way:
class Second {
@Persistent
@PrimaryKey
Key id;
@Persistent
First owner;
@Persistent
ListString tags;
First getOwner() {
if (owner==null)
owner = new First();
return owner;
}
ListString getTags() {
if (tags==null)
tags= new ArrayListString();
return tags;
}
...
}
Do I have to remove all the check of the type if (obj==null)
obj=new...?
Thank you very much for your help!

Beware that the only way you should ever store a Second object is:
myFirstObject.getList().add(mySecondObject);
pm.makePersistent(myFirstObject);
since Second.owner is mapped it's automatically populated by the
persistance manager.
Hope this helps,

Long id;

I do:
First obj = ...;
ArrayListSecond list = obj.getList();
for (Second s : list) {
System.out.println(s.getOwner());
}
In this loop, I find some Second object having null owner, and I
cannot understand why.
Now I have several questions about my data modelling:
1) Do I need to mark any field with (defaultFetchGroup = true)
annotation?
2) Does the check on null object (e.g. if (owner==null) owner = new
First();) in the getter methods results in any strange behavior?
3) Does the assignment on definition of objects (e.g.
ArrayListSecond list = new ArrayListSecond();) results in any
strange behavior?
4) Do I need to add any other annotation to owner field of Second
class?
Thank you very much for your help!!

Re: [google-appengine] Re: Retrying transactions
Hi Jeff, If you use Python it will retry 3x. The datastore uses optimistic locking and retries for transactions. If the transaction prepared by the function cannot be committed, run_in_transaction() calls the function again, retrying the transaction up to 3 times. (To use a different number of retries, use db.run_in_transaction_custom_retries().) Because the transaction function may be called more than once for a single transaction, the function should not have side effects, including modifications to arguments. http://code.google.com/appengine/docs/python/datastore/functions.html#run_in_transaction Not sure about Java, but they seem to keep things more-or-less consistent.

Eg: (copied mostly from http://code.google.com/appengine/docs/python/urlfetch/asynchronousrequests.html ) from google.appengine.api import images # ... blob_keys = [..., ..., ..] blob_key_serving_urls = [] size = ... crop = ... def handle_result(rpc): url = rpc.get_result() blob_key_serving_urls.append(url) # Use a helper function to define the scope of the callback. def create_callback(rpc): return lambda: handle_result(rpc) rpcs = [] for blob_key in blob_keys: images.create_rpc() rpc.callback = create_callback(rpc) images.make_get_serving_url_call(rpc, blob_key, size, crop) rpcs.append(rpc) # ... for rpc in rpcs: rpc.wait() # blob_key_serving_urls should now contain the serving URLs. Or should we add this as a feature request? Nick On 27 August 2010 10:56, Ikai L (Google) ika...@google.com wrote: Yes, you can cache the result. In practice, subsequent calls of get_serving_url on the same blob should be faster, but if you have more new blobs than old ones on a page it can be slow.

Would it be smarter to call get_serving_url if the blob has been created and store the image url in datastore?

[google-appengine] Re: *.appspot.com certificate chain in Chrome, Safari and IE
Sorry, you are right. The problem is that the Windows 7 certificate store does not have the Equifax root certificate out of the box (on Windows XP it does). The number of root certificates included with Windows 7 out of the box is actually quite low. The machines where I tested this and got an error (Windows 7 and 2008) are fully updated (including the root certificates update). However they are behind a proxy server, and maybe the root certificates update doesn't work over a proxy server. I manually installed the root certificates update again (http://www.microsoft.com/downloads/en/ confirmation.aspx? familyId=e4f9b573-66d7-4dda-95d5-26c7d0f6c652displayLang=en) with the machine connected directly to the internet and it populated the certificate store with the missing root certificates. I guess this is still a problem, but only for users that do not update or that are behind HTTP proxy servers (corporate users, mostly).

So cross-site limitations should not be an issue. Correct? With the current dev-channel-js.js that comes with the SDK I can't get this working. The dev-channel-js.js does not explicitly specify the hostname (and port) of the App Engine dev server. Instead just specifies the url (/_ah/channel/). This means that in my example case, it tries to connect to http://127.0.0.1:8000/_ah_channel/dev [...] Is this a use case that will be supported on production, once the channel API becomes publicly available? -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Your Suggestions Comments on Cascading Deletes Across Potentially Thousands of Entities
Hi all, I'm developing an application that has the following datastore models: StatusUpdate - members' distributed status StatusUpdateLike - members can mark a StatusUpdate as liked StatusUpdateLikeCounter - counter of # of members who like a StatusUpdate DistributionIndex - has a list property of member ids used to syndicate content to subscribed members Comment - a comment made by a member about a StatusUpdate CommentLike - members can mark a Comment as liked CommentLikeCounter - counter of # of members who like a Comment A StatusUpdate can have many Comments but there is no entitygroup relationship between them. A StatusUpdate can have many DistributionIndexes and both form an enitty group where StatusUpdate is the root of the hierarchy and DistributionIndexes are the children. A StatusUpdate can have many StatusUpdateLikes but there is no entitygroup relationship between them. A StatusUpdate can have many StatusUpdateLikesCounters (sharded) but there is no entitygroup relationship between them. A Comment can have many CommentLikes but there is no entitygroup relationship between them. A Comment can have many CommentLikeCounters (sharded) but there is no entitygroup relationship between them. When a StatusUpdate is deleted by the member who created it I am thinking I can approach 'clean up' in one of 2 ways I would like your opinions on both: 1) I can just delete the StatusUpdate and its child DistributionIndexes and leave all the other entities in place in the datastore. This would not impact the application because the StatusUpdate is the root of its logical hierarchy and without it all the other entities are ignored. Depending on the popularity of the application leaving these entities in place could result in the datastore maintaining thousands of orphaned entities. 2) I can go through the logical hierarchy and cascade deletion. Depending on the popularity of the application this could require the deletion of thousands of records. Though everything would be done using keys and batch deletes, deleting thousands of records couldn't be done in-process and would require kicking of tasks to perform the cascading deletes. 3) I could use a combination of the above. When a member deletes a StatusUpdate I could delete it and its associated DistributionIndexes and create a new entity that would serve as a marker for the deleted StatusUpdate. I could then schedule a task to kick off periodically that would query for the marker entities. If found I could kick off tasks to do the clean up out of process. The simplicity of approach #1 above is very attractive but I am concerned about its impact on the size and growth/datastore, The complexity of approach #2 #3 above concerns me because I would need to use tasks (I haven't implemented tasks yet on app engine) I don't know what a good implementation would require. What do you think about this? Suggestions comments welcomed. Jeff -- You received this message because you are subscribed to the Google Groups Google App Engine group.

1GB of data storage is free. Any data store usage above 1GB but less than 41GB (the max storage is something you can set when you configure your Billing Settings) will be billed to you. If you look at your billing report, it states that Used = 1.15, Free = 1.00, and Billable = 0.15.

Re: [google-appengine] Your Suggestions Comments on Cascading Deletes Across Potentially Thousands of Entities
Options 2 or 3 sound like good choices. Option 1 will leave 'junk' lingering around your datastore cluttering stuff up. Any operation you might need to run over all child entities will (potentially) need to be aware of orphaned records. Just seems like the kind of thing that will bite you down the road. With option 2 you need to do a bit more up front, but not much. Kick off a transactional 'deleted' task that analyzes the hierarchy and spawns any other needed tasks. That will let the delete handler return quick. Then the backend will clean itself up. Option 3 is very similar to option 2. The biggest benefit I see is that perhaps you can somehow batch delete operations more efficiently? I think you'll still wind up using the task queue to handle cascading deletes though, right? I guess you would basically pull the deleted entity markers, build some type of processing list and delete as much as you could before getting a timeout and repeat? Using task queues this could be probably be parallellized to be made more efficient. Not really sure my thoughts really add much. Currently In my code I use option 2 for a variety of things (updates and deletes). I just like it because it gets stuff done as close as possible to the user's action. Robert On Fri, Aug 27, 2010 at 09:15, Jeff Schwartz jefftschwa...@gmail.com wrote: Hi all, I'm developing an application that has the following datastore models: StatusUpdate - members' distributed status StatusUpdateLike - members can mark a StatusUpdate as liked StatusUpdateLikeCounter - counter of # of members who like a StatusUpdate DistributionIndex - has a list property of member ids used to syndicate content to subscribed members Comment - a comment made by a member about a StatusUpdate CommentLike - members can mark a Comment as liked CommentLikeCounter - counter of # of members who like a Comment A StatusUpdate can have many Comments but there is no entitygroup relationship between them. A StatusUpdate can have many DistributionIndexes and both form an enitty group where StatusUpdate is the root of the hierarchy and DistributionIndexes are the children. A StatusUpdate can have many StatusUpdateLikes but there is no entitygroup relationship between them. A StatusUpdate can have many StatusUpdateLikesCounters (sharded) but there is no entitygroup relationship between them. A Comment can have many CommentLikes but there is no entitygroup relationship between them. A Comment can have many CommentLikeCounters (sharded) but there is no entitygroup relationship between them. When a StatusUpdate is deleted by the member who created it I am thinking I can approach 'clean up' in one of 2 ways I would like your opinions on both: 1) I can just delete the StatusUpdate and its child DistributionIndexes and leave all the other entities in place in the datastore. This would not impact the application because the StatusUpdate is the root of its logical hierarchy and without it all the other entities are ignored. Depending on the popularity of the application leaving these entities in place could result in the datastore maintaining thousands of orphaned entities. 2) I can go through the logical hierarchy and cascade deletion. Depending on the popularity of the application this could require the deletion of thousands of records. Though everything would be done using keys and batch deletes, deleting thousands of records couldn't be done in-process and would require kicking of tasks to perform the cascading deletes. 3) I could use a combination of the above. When a member deletes a StatusUpdate I could delete it and its associated DistributionIndexes and create a new entity that would serve as a marker for the deleted StatusUpdate. I could then schedule a task to kick off periodically that would query for the marker entities. If found I could kick off tasks to do the clean up out of process. The simplicity of approach #1 above is very attractive but I am concerned about its impact on the size and growth/datastore, The complexity of approach #2 #3 above concerns me because I would need to use tasks (I haven't implemented tasks yet on app engine) I don't know what a good implementation would require. What do you think about this? Suggestions comments welcomed. Jeff -- You received this message because you are subscribed to the Google Groups Google App Engine group.
