[appengine-java] jdo update is inserting when I don't want it to
I'm new to jdo and GAE so I probably have some simple misunderstanding that
someone can quickly solve.
I have one servlet A that modifies an entity and another servlet B that
deletes the same entity. The problem is that when both are called at the
same time, the entity is being recreated after it was deleted.
What I mean is:
servlet A does
delme = pm.getObjectById( Thingy.class, sameKey );
Transaction tx = pm.currentTransaction();
try{
tx.begin();
pm.deletePersistent( delme );
tx.commit();
}
finally{
if( tx.isActive() ){
tx.rollback();
}
}
servlet B does
persistme = pm.getObjectById( Thingy.class, sameKey );
persistme.changeSomeValue();
Transaction tx = pm.currentTransaction();
try{
tx.begin();
pm.makePersistent( persistme );
tx.commit();
}
finally{
if( tx.isActive() ){
tx.rollback();
}
}
I would like servlet B to fail if the entity was deleted by Servlet A.
Instead, Servlet B just recreates the deleted entity. Anyone know what I
need to do here?
(the actual code is a little more complex than this eg the entity I am
modifying is actually a dependent child in an list of another entity)

[appengine-java] Indexing Problem...Defect
Hi,
I got a weird index problem
I had a entity claas A like his
Class A{
//Few properties
SetKey locationIds;
Date lastSaveDate;
}
and i was querying it like this
select * from A where locationIds = SomeKey order by lastSaveDate DESC
It was working good...
then i needed to add extra property adtype, so my class became
Class A{
//Few properties
SetKey locationIds;
Date lastSaveDate;
SetLong adType;
}
and my query is now(using low level datatsore APIs)
select * from A where locationIds = SomeKey and adType in Lit of types
order by lastSaveDate DESC
So to run this query i need to create a new index and i created it
I checked in admin panel all indexes were ready to server including new
one
now i had around 600 records in this table and i create done task to read it
and save it again... and i expected that it will re create new indexes
Now its not returning all my records..some records are not coming at all...
so on pages where i use to get say 15 records now i get like 8-9 records
just a subset is coming, and the records which are not coming should come
and they full fill query criteria
My older version of app is still shwoing those records but new is showing
only subset of that data. and there are no errors in error log...its
behaving as if these records do not exists.
Please help i am not sure what is happening

[appengine-java] downloading appengine logs to server that has no development environment
Hi, we'd like to download the appengine logs of our application to a separate machine that doesn't have the application's development environment available. We develop on workstations but the log download and analysis should run on one of our servers, automatically, i.e. there's no source tree (and I'd like to keep it that way). The way I found so far is this: * install appengine sdk on the server * create a directory structure such as app/WEB-INF/ somewhere * place application's web.xml and appengine-web.xml in resulting WEB-INF dir * run appcfg.sh as documented, pointing to above dir Works for me, but took me a while to figure out. What I'd like to know is whether there is either a better way to do this, or what the shortcomings of my approach would be.

What exactly are you missing? The fact that the backup may be missing recently committed data? By definition, backups always contain stale data. Omitting not-yet replicated data from a backup is not terrible nor unexpected. Perhaps you would like a 'checkpoint' feature? Suggest it in a ticket...

Well from reading: If your app uses the High Replication datastore, it is possible to copy data from the app, but Google does not currently support this use case I assumed the bulkloader would not be a viable solution to download the entire contents of my apps datastore. Is this the case or does it indeed work fine? Maybe I assumed wrong and it will work well enough, I'll test it when I get home. On Apr 26, 10:20 am, A.

[appengine-java] Always On and warm up requests
I'm trying to figure out how to configure our GWT app to avoid latency. At the moment, it isn't used much so the app loads new instances regularly. We've got warmup requests enabled and have turned Always On on for all three instances. At the moment, we don't have any servlets specified as load-on-startup because it's a GWT app so we don't really need any specifically loaded at start-up. With this setup, we still see the following log message several times a day: 1. 1. This request caused a new process to be started for your application, and thus caused your application code to be loaded for the first time. This request may thus take longer and use more CPU than a typical request for your application. Furthermore, on one particular page, we make two RPC requests to the server in succession. This log message often appears for both calls which suggests to me that they are each going to different instances and each one is launching a new process for the app. Is there something else we need to do to ensure the app remains loaded? We see some serious latency (up to 8 seconds) when these log messages appear. I was thinking we could have a dummy servlet that simply retrieves something from the datastore to ensure the application code is loaded but that seems like it shouldn't be necessary. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

This has been asked elsewhere, but not here; see: http://stackoverflow.com/questions/3324848/scala-on-google-app-engine-with-eclipse A Scala-based GAE project causes the Eclipse plugin to freak out on Scala sources, obviously because they're not Java sources.

In project Properties - Google - App Engine - Validation, I've tried adding all sorts of patterns to exclude these source files, including **.scala, **/*.scala, and even simply **/* and **. Nothing seems to prevent this exception, and it's quite annoying, as it causes the Eclipse Error Log view to keep popping up. Is there a known issue here with a possibly known fix?

So the setup is working but the DeferredTask / DeferredTaskServlet do not seem to look into the settings configured in queue.xml Can somebody confirm this? Do you have more information on how you determined that this is not working?

Re: [appengine-java] Re: How do I run DeferredTasks in a Unit Test
I'm not sure what this is not working (given that it worked previously).
I'll take a look.
The task is binary data. My first guess is this:-
String queuedTask = taskInfo.getBody();
String is UTF-16 encoded while the body is a bunch of bytes. The process of
decoding and re-encoding has a potential of corrupting the data.
I suggest using
*getBodyAsByteshttp://code.google.com/appengine/docs/java/tools/localunittesting/javadoc/com/google/appengine/api/taskqueue/dev/QueueStateInfo.TaskStateInfo.html#getBodyAsBytes()
instead.*

Re: [appengine-java] Re: How do I run DeferredTasks in a Unit Test
Thanks. I'll give that a try and report back. Do you know if the first approach I tried with LocalTaskQueueTestConfig.getLocalTaskQueue().runTask(queueName, taskName) should ever work from a JUnit test case, or will ServletUnit always be the way to go? It seems like something didn't work properly when it reported Local task queue initialized with base url http://localhost:8080;, as later on couldn't connect with Connection to http://localhost:8080 refused.

Re: [appengine-java] Re: How do I run DeferredTasks in a Unit Test
getBodyAsBytes() solves the problem.
The following code will run each of the queued DeferredTasks from within a
JUnit test.
String queueName = QueueFactory.getDefaultQueue().getQueueName();
ServletRunner sr = new ServletRunner();
sr.registerServlet(
/_ah/queue/__deferred__,
com.google.apphosting.utils.servlet.DeferredTaskServlet.class.getCanonicalName());
LocalTaskQueue localTaskQueue =
LocalTaskQueueTestConfig.getLocalTaskQueue();
ServletUnitClient client = sr.newClient();
while (!getQueue().getTaskInfo().isEmpty()) {
TaskStateInfo taskInfo = getQueue().getTaskInfo().iterator().next();
byte[] taskBody = taskInfo.getBodyAsBytes();
String taskName = taskInfo.getTaskName();
WebRequest request = new
PostMethodWebRequest(http:/_ah/queue/__deferred__,
new ByteArrayInputStream(taskBody),
application/x-binary-app-engine-java-runnable-task);
request.setHeaderField(X-AppEngine-QueueName, queueName);
try {
client.sendRequest(request);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SAXException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
localTaskQueue.deleteTask(queueName, taskName);
}
}
localTaskQueue.flushQueue(queueName);

[appengine-java] Re: low level datastore and numbers
Yes. Stick the int var in your class with @Persistent. @Persistent private int myInt; http://code.google.com/appengine/docs/java/datastore/entities.html#Properties_and_Value_Types Casting from long to int should not throw anything I'm aware of. It might truncate a number into int. long test = 1234; int myInt; myInt = (int) test; should not throw.

[appengine-java] Re: jdo update is inserting when I don't want it to
pm.makePersistent( persistme ); is called after the deletion it will recreate it. You'll have to query it by objectid first and see if it exists. If it exists you could update. SQL would need an ID to update, but in JDO, it will make a new ID on insert and update depending on existence. like so: MyClassJdo exists = pm.getObjectById(MyClassJdo.class, keyId); Brandon Donnelson http://gwt-examples.googlecode.com -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: Timeout when trying to upload to Blobstore (files 5k)
Hmmm, I can't see anything obvious. I know this can be be a bear b/c I've done it too. 10 seconds is all you got, unless you move to a task. Although, it will allow you to load any size file to the store, but after its loaded you got 10 seconds to do processing. It shouldn't hang. Can you find the file in the blobstore after running above and before you think it hangs? It should be before you hit the upload servlet? http://code.google.com/p/gwt-examples/wiki/DemoGAEMultiFileBlobUpload - here are some more notes I put together on blob stuff http://code.google.com/p/gwt-examples/wiki/gwt_hmtl5#Upload_Canvas_Image - another thing I do to upload Brandon Donnelson http://gwt-examples.googlecode.com -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: Performance of blobstore upload API vs the new files api
I've done them all and don't see any difference in the apis. The File api has a few bugs and is experimental, at least I think thats the one your talking about. I prefer the HTML post method b/c its well defined, and there are libs available to put together a post. Its a multistep process, one to get the blob url, which is very fast and then post and wait for upload. I figure either road you take same steps different way. Some more notes with demos. I made an java app with source there to that uploads from desktop. - http://code.google.com/p/gwt-examples/wiki/DemoGAEMultiFileBlobUpload Good luck in your adventure, Brandon Donnelson http://gwt-examples.googlecode.com -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.
