[appengine-java] cache expiration
In my application, I get values from captors
Each value has a 5 minute validity. Each read from a captor cost a
lot, so I've tried to put it in the GAE cache
My code (JCache or low level api) is working with the cache as long as
I don't use the exoiration delay.
When I use the expiration delay, it works fine as long as the
expiration delay isn't spent. After, a get(key) on the cache always
gives null and a put(key,value) doesn't change that.
The same problem seems to be describded here
http://groups.google.com/group/google-appengine-java/browse_thread/thread/4e562762f13d932e/a974365a918b279d?lnk=gstq=JCache+expirationpli=1
and in other messages on the web
Here is a view of my code on the low level API
key = num;
foo = (String)cache.get(key);
if (foo == null) {
foo = /* get the value */
cache.put(key, foo, exp, MemcacheService.SetPolicy.SET_ALWAYS);
}
resp.setContentType(text/xml);
resp.getOutputStream().print(foo); }
where exp is declared as a global by
static Expiration exp = Expiration.byDeltaSeconds(300);

[appengine-java] Is it possible to add a member to a detached object's collection that wasn't itself detached?
In case my subject line was confusing, I'll elaborate: Let's say I have a parent object that has a collection of children. I detach that parent object and intentionally omit the collection of children from the fetch group, in order to avoid fetching the potentially numerous children. Then, I want to add a new child to that parent's collection. I thought I would be able to add that child to the parent's empty un- detached collection, and thus have a child-collection size of 1, and then have that child be added to the parent's collection of children when the parent is attached. This code gave me an illegal access of field that wasn't detached, if you want to access this field please detach it exception. The reason that I thought this was possible was the following lines from the JDO docs: If you don't detach a field of an object, you cannot access the value for that field while the object is detached. If you don't detach a field of an object, you can update the value for that field while detached, and thereafter you can access the value for that field. (http://www.jpox.org/docs/1_2/jdo/attach_detach.html) The second line pertains to what I'm doing (updatingthe value for the field while detached), but I guess in so doing I am also trying to access the value for the field. In short, is what I'm trying to do possible? Cheers, Mike -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

The *anything* can be side-effects all over the code so I found it
easier to deal with it in one place. Here is the code to get the
version number. Perhaps there is a simpler way.
String getAppVer() {
String sPath = System.getProperty(user.dir);
if (sPath == null) return 99;
int nIX = sPath.lastIndexOf(/);
if (nIX 0) return 888;
return sPath.substring(nIX+1);

[appengine-java] Re: Filter's static variable is lost
Hi,
you could use a Servlet Content Listener, which will tell you when the
Servlet context starts / stops ... you'll at least know when Google are
loading or unloading your app.
But this doesn't help solving the problem I described above.
if you truly have to do some
initialization each time the JVM starts,
I mean the opposite. I don't want to do initialization every time
Google loads my app. I will convert all static variables into
datastore entries. Instead, I want to save the state for a lifetime,
until a new deployment is made. I think you assumed I was writing
about loading, but I meant deployment.
So, my question is how to determine a new deployment(uploading the
new application with the same version name) in my app
programatically.
Thanks,

from reading your email however, it seems like there maybe a little
confusion around app initialization. if you truly have to do some
initialization each time the JVM starts, you won't want to store
initialized in the datastore as if / when other instances are spun up they
will be in an inconsistent state than what you want.
it seems like you want this initialized state on a per context basis.

Deploying a new version has no effect on data stored in the datastore.
What do you mean by initialize your app. If you are referring to
loading
data into memory then that needs to be done for every instance of your app
that is loaded. Not just once per deployment.

Ok, I understood this one. However, I think you should warn the
developers not to use static variables at all, in a large and red

In this case, assume that every static variable is converted, and they
all being set from Datastore.
However, this does not solve the problem.
Let me explain an example:
* After deployment, at the first request, let me put a flag,
initialized=true, into datastore
* On later requests, my app does not need to be initialized, since I
get initialized=true from Datastore. Everything is cool.
* Let's make a new deployment to App Engine at this stage.
* After deployment of a new version, my app needs to be intialized
again
* In the code, once again I check my initialized flag from Datastore
is true, since a new deployment doesn't clear the stored data,
right?
* How to determine that a new deployment is made, and the
initialization needs to be run again?
What are the effects of a new deployment to the Datastore?

The only thing you can do about it is tackle the HDEEs which is not always easy. It sounds like they might be due to long start-up time? If so there are a number of tactics you can use to reduce this: Use lazy initialization as much as possible. Split your app into a user facing version and an admin version that share the same datastore If you use Guice try using the non-AOP version that does not enhance classes at startup Spring - not sure but others mentioned turning off classpath scanning Try reducing external jar dependencies - not sure how much affect loading these has If the cause of the HDEEs is that your requests take a long time then you'll need to reduce processing time Try using the Deferred class: http://groups.google.com/group/google-appengine-java/browse_thread/th...

In one request it took 45 seconds of CPU to return the favicon.ico file. I guess this is really related to starting a server instance, but if that's true then the server is going down after only a few seconds of use. It is starting the server handling a request and a few seconds later dropping the server. It isn't even staying up a minute.

The application is really just the scaffolded edits on this table with very few modifications to make it work. So it doesn't really do anything. About one in five clicks result in an error. The exception is a Hard Deadline Exceeded and there is a warning about the CPU limit as well. Randomly a request will take around 30 seconds of CPU for no reason. There is no change in the code. There is no change to the data. The exact same request will return with essentially no latency and then it will take 30 seconds of CPU. I thought this might be some kind of weirdness withGrails, but there are several issues listed that seem to be related to same issue: http://code.google.com/p/googleappengine/issues/detail?id=2621http:// ... ?id=2840http://code.google.com/p/googleappengine/issues/detail?id=2691http:// ... ?id=2837http://code.google.com/p/googleappengine/issues/detail?id=2846 I've stared them all because they all are likely related to the same problem I'm having. I was hoping that someone here knew what was going on and might be able to help me resolve it. In one of the messages above someone mentions moving an application to another shard to solve the problem. What does this mean? Is it really a potential solution?

[appengine-java] Re: Parallel Asynchronous Datastore Commands with Twig 1.0
I'm interested in the asynchronous datastore commands. How does it work behind the scenes? I'm using the low level datastore API and think asynchronous writes could be really useful for my project. I browsed through the low level api docs, but couldn't find a way to do an asynchronous command. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.
