[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...

[google-appengine] Re: Does App Engine throttle requests from a particular IP address?
An update. As an experiment, instead of sending the requests sequentially in the loop I now send every request from within a new thread. It improved things quite a bit. The requests arrive to the server milliseconds apart. The end result is that the client is done within about 5 seconds for the same work load that used to take 12 sec/item (overall that's about 2 orders of magnitude faster) However, instead of 200-500 ms it now takes more than 4 _seconds_ for a single request to complete on the server. Assuming app engine allocates 30 handlers per app you would think 25 items could have been processed at the same time as not much else was happening in the app at the same time. However it definitely looks like all the requests were processed by the same single handler. Any clues? -- You received this message because you are subscribed to the Google Groups Google App Engine group. To post to this group, send email to google-appeng...@googlegroups.com.

[google-appengine] PolyModel _kind_map shortcomings
Hello Group, I am in the process of writing an application that manages many diverse kinds of data, with a Connection model that connects any two fragments of information together. I originally evaluated a couple of ways to store this data (regular models, a single expando type, etc) until I was eventually convinced PolyModels would solve my design issues. I have written the application with a root polymodel called 'E', which everything in the application eventually inherits from. Examples: E-Person E-Role-Doctor E-Geoarea-Code-Zip Reasons for choosing this design pattern: 1) Ability to query for properties that exist on E, and so are shared by every model. 2) Reference properties can link to anything, because a link to E is a link to any other model. 3) Organization for property inheritance seemed to make sense 4) Very little or no performance impact in testing However, I have run into a number of problems with this design model. First, PolyModel subclasses aren't registered in the _kind_map, yes? Which means, as far as I can tell, that I can't do very basic queries on E. For example, E.all().fetch(100) fails with a No implementation for class error, presumably because the subclasses it returns have not been imported. Same when I try to use a PolyModel using the bulk uploader tool - it also checks the _kind_map for the entity you're trying to create. How can I fix this? Is there a way to register my sub-polymodels in the _kind_map, or a way to automatically import the module a class belongs to once it is looked for? If there is no way to fix these problems, I'm open to other ways to solve.

[google-appengine] Re: Storage for geo-points
Thank you for your reply. I have two opensource projects taking two slots and this one would take yet another. So I wrote as detailed as possible description of making its demo run on localhost with dev_appsver. If a couple more opensource projects would come up I would definitely fill the form.

[google-appengine] Suggestions on implementing aggregate like datastore functionality
Hello... I'm writing a django based app on GAE and I have models that I need to calculate things like averages, max, min, and other similar aggregate functions across various fields amongst entities in the datastore. Typically with a relational db this is accomplished with a standard query, but not with GAE. I've decided that it would be best to implement a different model to keep track of all of the averages, totals, etc. whenever updates are made. Originally I was thinking that I could offload the processing to the taskqueue, which sounded like a good idea, but before I get myself in too deep I want to check to see if anyone has a better suggestion to implement such tasks. I expect that the data in my application will be significant so an efficient solution is needed. Thanks in advance.
