[appengine-java] Capabilities related tests
Hi all, I'd like to be able to test how my application is behaving in the case of some Capabilities are not enabled. For example, what happens when Capability.DATASTORE_WRITE has a status of DISABLED. I had another look at the testing jar and its various classes, but I didn't find a way to see whether we could manually set some capability statuses. Is this something that is possible?

[appengine-java] Re: JDO unique Long ID keys across entity groups
Thanks guys! Think I'll just concatenate parent and child ID for display purposes and keep the rest as it is. Fred On 1 Okt., 08:16, John Patterson jdpatter...@gmail.com wrote: You can use DatastoreService.allocateIds() to get a range of unique keys that you can then assign to the children. The kind name can be any old String - not just an existing kind. This method does not guarantee the ids will be sequential but they will be unique. If you really need sequential ids you can use memcache's atomic increment method. If the value is not found in memcache you can do a query to find the maximum sequence number in the datastore and use the memcache increment method that allows you to specify an initial missing value atomically. John On 30 Sep 2010, at 17:28, Fred wrote: Hi Group, I know key ids are only unique across entity groups so what GAE + JDO gives me is: /Parent[1]/Child[1] /Parent[1]/Child[2] /Parent[1]/Child[3] /Parent[2]/Child[1] /Parent[2]/Child[2] /Parent[3]/Child[1] etc. What I need to achieve (aka implement) is a way to assign keys in the following fashion: /Parent[1]/Child[1] /Parent[1]/Child[2] /Parent[1]/Child[3] /Parent[2]/Child[4] /Parent[2]/Child[5] /Parent[3]/Child[6] etc... so child ids are in sequence across entity groups (or at least unique). Does anyone have experience with this or any thoughts on how to go about it in a secure fashion? I can't seem to come up with a secure way of doing this, but don't want to give up on it because it would give my use case a lot of querying power. Hope someone can help.

[appengine-java] Re: allocateIds performance
I have two classes. The first class contains a reference to the second. One service request might generate several such pairs. So I figured that I can batch store them at the end of the service request. To do that I need to generate ID-s for all the second classes. I thought that allocateIds was what I needed but from the tests I made (it sometimes took much longer to execute than other times) I suspected that it sometimes goes to the datastore. Ideally I would like to avoid going to the datastore just to generate the Id-s. What is the best way to accomplish this? To answer Your second question I haven't had time to play with AppStats yet. I measured time using System.nanoTime(). Thanks for Your time.

[appengine-java] Developing an AppStore for a GWT / App Engine application?
hello everyone, i want to build an app store for a GWT application. users should open the app store from within the application, browse through apps and install them like they are used to it from other app stores e.g. apple app store or android market. i outlined my ideas about it in the wiki of my project http://code.google.com/p/honeycrm/wiki/Plugins (including a more detailed description of the store, apps and sequence diagrams of the installation process). - has something like this been done before? - are there any best practices on this topic? - is it realistically i.e. a good idea to put source code into the plugin package (e.g. a zip file) and do the transformations (compilation of .java - .class using javac and .java - .js using GWTs compiler)? see http://code.google.com/p/honeycrm/wiki/Plugins#installation_of_plugins - can i do this within google app engine or do i have to use another servlet container e.g. for compilation. kind regards, ingo -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] Select query using LIKE
Use a GREATER_THAN_OR_EQUAL and a LESS_THAN filter to match a prefix - thats the best you can do for a single stored term.

So I would like to know what can separate each user connected with a google account. Could I have something like the PHP session for checking if a user is logged in? How I could also make relationship in datastore objects like relating 2 sql tables for example.

[appengine-java] Tell data store not to selected index properties on bulkupload
Hello, I would like to disable indexing for properties I know I won't be using for query filtering to save storage space. I have used bulkuploader to push ~500mb of data into the datastore. These Entities contain lot's of properties which won't be used for filtering, for ex. CountryName I would like to exclude these properties from the indexing, and purge the existing index. Not sure about how datastore works, so I'll ask all my questions at once: Can I disable indexing for properties or does single property indexes always created without me being able to control it? Can tell app engine to truncate existing index and not recreate it (to reclaim the disk space) ? Can I retrospectively upload an index.yaml file (I did not had this file before) to delete the unneeded indexes created? Will this index.yaml configuration will take effect on my next bulkupload operation as well? Thanks for helping, Maxim.

[appengine-java] Re: Google App Engine MUD
If the client access server with HTTP, GAE is definitely OK. But in my experience, Telnet is a better protocol for Mud/BBS. And I think GAE do not support socket function. If GAE support WebSocket, it will be a good way to approach that... (but I am not sure about this feature.) The most important thing is that it's very difficult to write a MUD including MUD OS/MUD Lib/MUD compiler... It's not a easy job. On 10月2日, 上午11時02分, MLS mlsjunkm...@gmail.com wrote: My friend and I are looking to rewrite an old BBS MUD. The game is a few thousand rooms and purely text based with commands issued by individual players and the game responding and updating players stats based on the results of their commands. I do not have a programming background, and I'm wondering about the best way to approach writing it for GAE. Attempting to translate the game to objects, I have the following layout: World object holds all of the zone objects, zone objects hold rooms, room objects hold players, player objects hold inventory objects, spellbook objects, and attributes. Then write appropriate methods for manipulating the objects appropriately and returning the results. I have a few questions though: 1. Is this a technically correct way of approaching the problem? If not, what would be better? (keep in mind, I am not a professional programmer by any means. I can find my way if I have something already written to make changes, but I've never written anything from scratch before). Would I populate all these objects, then write world to the db and retrieve it for each player action? I have no idea how servlets work to store state, or really how they work in general really. Basically, how would I be storing and retrieving stored player statistics which are constantly changing many times a second as players play the game. 2. A key issue is the ability to push updates to players in real time, and track individuals who are connected. For example, I would like the ability to be able to call something like room[someroomnum].sendtoall(Some message here); to push a message to all players in that room, or player[someplayernum].send(some message here); to send replies to players directly. I understand this is a complex issue with the stateless http protocol, but I have read some about the upcoming channel API which sounds like it may offer this ability but I don't know enough to be certain. Overall I'm looking to avoid devoting countless hours to this project if it is going to be beyond my abilities to complete successfully.

Can I retrospectively upload an index.yaml file (I did not had this file before) to delete the unneeded indexes created? Will this index.yaml configuration will take effect on my next bulkupload operation as well? Thanks for helping, Maxim.

This isn't the full stack trace so it's difficult to be sure, but do you store AbstractEngineResponses in an HTTP session? If so, it seems that the class is no longer compatible with the version stored in your session. If so, try clearing your cookies. This will create a new session for you.

[appengine-java] Object references imply ownership?
I'm using JPA, and I'm having a really tough time getting around this
problem. It seems that when I try to refer to an object by way of a
@ManyToOne, somehow DataNucleus wants to assume some kind of ownership
and throws an exception.
I have three kinds of objects: Person, Book, Rating. Person and Book
objects are independent of one another and created independently. When
a person rates a Book, a new Rating object is created and added to a set
of Ratings owned by the Person. The Rating object has a reference to
the Book. Here are the classes (each extends a superclass that contains
the @Id element):
class Person extends BasicEntity {
private String email;
@OneToMany(mappedBy=person, cascade=CascadeType.All,
fetch=FetchType.LAZY)
private SetRating ratings;
}
class Book extends BasicEntity {
private String name;
}
class Rating extends BasicEntity {
@ManyToOne(fetch=FetchType.LAZY)
private Person person;
@ManyToOne(fetch=FetchType.LAZY)
private Book book;
private Integer value;
}
I get the following exception when I attempt to add such a Rating to a
Person:
org.springframework.orm.jpa.JpaSystemException: Detected attempt to
establish Person(1)/Rating(3) as the parent of Book(2) but the entity
identified by Book(2) has already been persisted without a parent. A
parent cannot be established or changed once an object has been persisted.
What gives? Is it not permitted to refer to objects in this way? I've
been using this technique in JPA for years.
Thanks,
Dave

[appengine-java] Getting a LOT of mysterious 500 responses
Hi, on our tiny little web service http://findbugs-cloud.appspot.com, we're getting a whole lot of 500 responses, with a mysterious message. It started a few months ago and has slowly but steadily gotten worse since. Since a 500 response makes our continuous build fail, it's getting irritating... Request was aborted after waiting too long to attempt to service your request. This may happen sporadically when the App Engine serving cluster is under unexpectedly high or uneven load. If you see this message frequently, please contact the App Engine team. Also irritating is that these only show up as warnings so sometimes I don't even notice they're happening. Any idea what's going on? Are we just on a bad cluster? Can we get moved somehow? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] Object references imply ownership?
Hi,
I have encountered similar error using JDO long time back. I firmly believe
that if you use @ManyToOne or something it means a relationship amongst
them.
Though I don't remember exactly what I did ,Coupleof observations
1. In the rating class. Add annotation of rederenced by attribute in
annotation. Or a similar annotation needs to be done in Book class.
2. Person has a list of rating and rating again has a person. Are you
planning to query by rating entity independently? I think this design tells
JPA that a person indirectly owns a book.

[appengine-java] Re: Google App Engine MUD
Hi Fattom, Thanks for your response. I don't think most browsers support Websockets quite yet, and I don't want to tie people to a specific one. What is the most challenging part of writing a MUD for http aside from real time delivery, which I'm hoping Ajax push solves? Aside from that I believe I can write the methods required to produce the output that is expected from the various commands in the game I plan to implement, and can manage player attributes with player objects and back them with a nice database. I could certainly be missing something crucial though, so please let me know. To me it sounds much more difficult to write a client and server using telnet. Thanks, MLS On Oct 3, 10:55 pm, 番頭Fattom fattom.rid...@gmail.com wrote: If the client access server with HTTP, GAE is definitely OK. But in my experience, Telnet is a better protocol for Mud/BBS. And I think GAE do not support socket function. If GAE support WebSocket, it will be a good way to approach that... (but I am not sure about this feature.) The most important thing is that it's very difficult to write a MUD including MUD OS/MUD Lib/MUD compiler... It's not a easy job. On 10月2日, 上午11時02分, MLS mlsjunkm...@gmail.com wrote: My friend and I are looking to rewrite an old BBS MUD. The game is a few thousand rooms and purely text based with commands issued by individual players and the game responding and updating players stats based on the results of their commands. I do not have a programming background, and I'm wondering about the best way to approach writing it for GAE. Attempting to translate the game to objects, I have the following layout: World object holds all of the zone objects, zone objects hold rooms, room objects hold players, player objects hold inventory objects, spellbook objects, and attributes. Then write appropriate methods for manipulating the objects appropriately and returning the results. I have a few questions though: 1. Is this a technically correct way of approaching the problem? If not, what would be better? (keep in mind, I am not a professional programmer by any means. I can find my way if I have something already written to make changes, but I've never written anything from scratch before). Would I populate all these objects, then write world to the db and retrieve it for each player action? I have no idea how servlets work to store state, or really how they work in general really. Basically, how would I be storing and retrieving stored player statistics which are constantly changing many times a second as players play the game. 2. A key issue is the ability to push updates to players in real time, and track individuals who are connected. For example, I would like the ability to be able to call something like room[someroomnum].sendtoall(Some message here); to push a message to all players in that room, or player[someplayernum].send(some message here); to send replies to players directly. I understand this is a complex issue with the stateless http protocol, but I have read some about the upcoming channel API which sounds like it may offer this ability but I don't know enough to be certain. Overall I'm looking to avoid devoting countless hours to this project if it is going to be beyond my abilities to complete successfully.

Re: [appengine-java] Object references imply ownership?
Hi Hari,
I don't follow what you're saying in #1 below.
#2 - This is just the way I have always modeled classes using JPA. In a
relational database, the @ManyToOne would cause the key of the owning
entity to be stored in the row. In this case, the Rating table would
have a column to hold the Person_Id. It's unclear to me how this works
with the DataNucleus datastore in GAE. Here's an example of a similar
relationship that is supposed to work in GAE:
http://gae-java-persistence.blogspot.com/2009/10/creating-bidrectional-owned-one-to-many.html
Obviously, the difference is that I have another @ManyToOne that
references another entity type.
I've always felt like I had a firm handle on JPA, but using it with GAE
has been a very discouraging endeavor, so far.
Thanks for the feedback,
Dave

Re: [appengine-java] Object references imply ownership?
On point #1, there is a way in JdO to say which attributes forms a relation or forms a join between two entities. It need not be the primarykey always. Also I don't think having more than 1 @ManyToOne relation should be a problem. I might need to look at my app code in the evening to see how did I solve the problem.

Re: [google-appengine] Data partitioning by entity name conflicts with App engine custom index architecture
Hi, There is no need to partition your datastore. If you're concerned about performance, don't be - App Engine can handle as much data as you can throw at it. If you're concerned about isolation, you should look into namespaces, as Tim Hoffman suggests. -Nick Johnson On Sun, Oct 3, 2010 at 10:37 PM, DutrowLLC dutrow...@gmail.com wrote: I chose to partition data between different users by adding a post-fix to all entity names. So instead of having a PhoneCall entity, I had PhoneCall_r35wk, with the random sequence r35wk corresponding to a particular user. There could be thousands of PhoneCall_ entities, each with a different name. I figured this would be a good architecture since user's data would be completely partitioned. Also, I would eliminate an equality filter for each query (ie: userId EQUALS 123456) It turns out this architecture seems to conflict with another aspect of App Engine that was seemingly unrelated. And thats the need for adding custom indexes through the index.yaml file (or executing each query on the dev server). For a while, I had no need for custom indexes, but recently I had need to execute this query which seemed to require a custom index: Pseudo-code: SELECT * FROM CallRecord_27sjakla WHERE callerId IN [703-678-9832, 540-892-2191] // number is a String ORDER BY startTime DESC // startTime is a Long integer This problem of needing to manually pre-define custom indexes for entity names that are not pre-determined could be solved if there was a way for the application to programmatically add to the index.yaml file (I did not see documentation for this). However, even in this case, I have concerns that the index.yaml file would grow to become very big and cause problems with the application taking too long to initialize. Is there another way that I should be handling this situation? Is there are better way to add these custom indexes? Should I be partitioning user data differently? -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] Re: Latency related follow up
Hi, Thanks for your feedback. That is good to know. I think I am handling errors reasonably well but there is only so much an app developer can do to handle the errors. Ultimately, it is the end user that will need to resolve the error. Here is an example: When an end user tries to post a message (which talks to GAE custom service), sometimes an error occurs. I am able to handle this error by either queuing for offline sending or just letting the user to know to retry. The latter case is in and of itself is bad. Same feeling that I would have when I compose a long mail in Gmail and SEND fails and asks me to retry. Here is another scenario that I am even concerned about: I want to notify users that they have a new message. I am thinking of employing hooks from within GAE to notify users that there is a new message (via a payload that indicates the message identifier). Now, when the users try to open the app and see what the messages were, they ought to get the new messages. Well, based on the GAE errors (i.e request aborted errors), that is going to be a hit and miss. When this happens, the users are going to get annoyed and feel that they are being spammed or tricked into accessing the application. Google Folks, I understand that you are working towards resolving this. Any further updates on when you will be able to resolve this. This is probably a no but I will ask any way - as a GAE developer, is there anything that we can do to avoid Request aborted error scenarios? Are you planning on reserving instances type model to get around this? Thanks.

Different namespaces share the same quota on Datastore for example? thanks Michele -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] Could I recover the application that all associated developers account has deleted ?
My earlier email was incorrect - if all developers are removed, the application will serve for one month before it is permanently deleted, since this is the recovery period. I've reenabled the application. This application has not gone through the irreversible stage yet, so it's a good thing we recovered it now. I can readd you as a developer, but can you verify that you own the account? Email me the auth domain you are using (it's a very strange looking one) and I'll add this Gmail address you're using back to the list of developers. When you delete user accounts, there should be a warning in the domain dashboard about data/apps being deleted. How can we better warn developers of this behavior? We can't email the developers, since their accounts were deleted, and if you delete a developer account, you can't log into the admin console. -- Ikai Lan Developer Programs Engineer, Google App Engine Blogger: http://googleappengine.blogspot.com Reddit: http://www.reddit.com/r/appengine Twitter: http://twitter.com/app_engine On Fri, Oct 1, 2010 at 12:03 PM, Ikai Lan (Google) ikai.l+gro...@google.comikai.l%2bgro...@google.com wrote: What's the application ID?

[google-appengine] Appengine - Reportlab (Get Photo from Model)
Hi, I´m using the latest reportlab version 2.5 to generate PDF´s.
I´m also using Google App Engine and Django.
I can get also an image that is in my source folder. Ex: for heading
or footer.
Everything went well to generate the PDF, but I'm having great
difficulty printing to a PDF an image that an user uploaded, like his
own photo.
The photo is a property and is defined in model as BlobProperty ().
Handler:
class savePDF(webapp.RequestHandler):
def post(self):
user= models.Users.all()
p = canvas.Canvas(self.response.out)
p.drawString(50, 720, 'Curriculum Vitae : '+ '%s' %
user.name)
image = canvas.ImageReader(StringIO.StringIO(user.photo))
p.drawImage(image, 40,700)
Model:
class User(db.Model):
photo = db.BlobProperty()
name = db.StringProperty(required = True)
View:
table align=center
tbody
tr
tdUpload Photo: /td
tdimg src=/uploadFoto //td
/tr
tr
tdUser Name: /td
td{{ user.name }}/td
/tr
tr
tdUser Photo: /td
td{{ user.photo }}/td
/tr
Note: I´ve modified utils.py this post.
I´m getting errors like this one:
File C:\Users\hp\workspace\x-ray\src\principal.py, line 441, in post
image = canvas.ImageReader(StringIO.StringIO(user.photo)) File
reportlab.zip\reportlab\lib\utils.py, line 588, in init File
reportlab.zip\reportlab\lib\utils.py, line 582, in init
RuntimeError: Imaging Library not available, unable to import bitmaps
only jpegs fileName=StringIO.StringIO instance at 0x04A5A030
identity=[imagerea...@0x4a62290].
Please note that i uploaded an .jpeg image.
So, i don´t get the error. If someone could help, i´d be very happy.
The problem that i´m facing right now is when a user upload a photo,
isn´t displayed on his PDF.
I´ll show you a short pic tinypic.com/r/2ngeont/7, but the image shown
is uploaded by me not by the user.

[google-appengine] Request log retention: are they archived at Google?

[google-appengine] Unable to upload app - was working the other day
I have an app - available at app.myshopus.com. The app name is myshopus, deployment worked fine on Friday. Today when I try to appcfg.sh update war it asks for email and password (as it should). I type them in (checking for caps lock, etc - they are correct) and it asks for them again. I do this three times and then it gives me a com.google.appengine.tools.admin.ServerConnection $ClientLoginException: Unknown Unable to update app: Unknown Please see the logs [/var/folders/Yh/Yhnhi3+QFV4IJTTQK9q4bE+++TI/-Tmp-/ appcfg5952276576316662153.log] for further information. The log gives me the following stack trace. Looks like I'm getting a 403 forbidden response for URL: https://www.google.com/accounts/ClientLogin The same credentials worked on Friday . . . I know that I got some strange issues where I set up Google apps for domains for this domain and it was telling me that pe...@myshopus.com was already in use so I couldn't use it as part of the domain, but with some futzing around last week I was able to convince Google that pe...@myshopus.com was indeed part of the apps for domains for myshopus.com and it allowed me to use those credentials to log in and assign the app to that domain. Any thoughts on how to fix this or what's going on? Stack trace below. Any input appreciated!

Re: [google-appengine] Re: Latency related follow up
Thanks for your suggestion. I will take a look at the appstats one more time. What I am noticing though is api_cpu under 500ms (and many much below that) but sometimes overall cpu overshoots 700 ms. More over, for request aborted error messages, it doesn't really look like the service is even called - overall cpu in those instances is over 1 ms but api_cpu is 0 ms. Am I interpreting this right? I have seen old posts where users recommended a cron and I tried that out today with surprisingly positive results. Other than this potentially causing few instances to stay alive, I can't think of any other explanations. Any one why that is better? In any case, I wonder if that is going to really help if concurrent requests increase and demand more active instances. Thanks.
