Excellent! Shouldn't the issue 2782 be marked as fixed?

Re: [appengine-java] Re: App Engine cold starts and overly aggressive cycling

2010-04-22 Thread Esteban Ignacio Masoero 
Yes, I've done the same thing. In my case, the numbers about initialization
are these:

3 sec - gae (apparently some internal thing)
2 sec - presentation framework initialization (wicket in my case)
4 sec - 2 sec for pm factory creation + 2 sec for 2/3 queries I make
1 sec - wicket and maybe some other gae stuff

I'm working on reducing my 4 sec part, but it's really dificult, because the
queries are done with a pk, so I think I can't do anything else.

By the way, I voted your issue! Hope Google guys give this matter some
urgent attention, because I think it's really serious problem.

Regards,

Esteban

Hi there:

I'm experiencing the same issue. From what we've seen, after 5 minutes of
being accessed, our app gets "cycled out". Are there any news about this?
Has anyone created an isue about this problem?

Re: [appengine-java] Re: Clear particular session manually

2010-04-17 Thread Esteban Ignacio Masoero 
Seleronm:

Thanks for the suggestion, but sadly I've already tried that solution
without success. I got all the _ah_SESSION entities, deleted them from the
datastore, and also deleted them from the memcache, but it didn't work.

I'm convinced that the admin console should provide a feature to remove
sessions, not only inactive ones but also active ones (which of course is my
case).

Is there some Google developer around? Please, this is keeping us from
deploying new versions because we don't want to have to tell the users "you
need to delete your cookies so the site can work again".

Thanks,

Esteban

Thomas, thanks for the response. I tried deleting all entries for

I'll try what you said about the web.xml, if it's possible it should be much

that where serialized as part of the session (this is natural in a wicket
app, as it is mine),  every user that was already logged from before the
deploy gets this ugly "local class incompatible" error, which to make things
worse is not possible to catch by the app, and the user only sees an empty
white page.
The error makes sense, but I'd like to ask:
- Is there a way I can programatically (or from the admin console would be
best) make all session cookies expire?
- Would it be possible to make this exception "cacheable" by the app, so we
can at least show some proper message?

At the end of this email I'm adding the exception stack trace.

Thanks in advance,

Esteban

[appengine-java] ImagesService misunderstands an uploaded file's size the first time

2010-04-14 Thread Esteban Ignacio Masoero 
Hi there:

I'm having the strangest problem.

The first time I use the ImagesService (i.e. after it was recently deployed)
to transform an image, I get an "ApiProxy$RequestTooLargeException: The
request to API call images.Transform() was too large." exception and if I
look at the com.google.appengine.api.images.Image size attribute
(image.getImageData().length), the size has nothing to do with the real size
(for example, it says it's 2942Kb when in fact it's 16Kb, and I'm sure about
this because I logged the size before calling the images service and I got
the smallest one).

The second (or third) time I use the ImagesService, It works well, but it
seems that I need to call it with a different image. Then, when it's working
fine, I can call it with the "problematic image" (the first one) and it also
works fine.

Apparently it has nothing to do with the image itself, because I tried with
different images and it's always the same, the first time it doesn't work.
To make things even worse, my app is also deployed in another
(pre-production) gae environment, and in that environment it works fine!!!

Can anyone from google take a quick look at this? I can send them the app id
if they want to. Has anyone experienced some problem alike?

Thanks,

Esteban

Re: [appengine-java] Strange characters showing in incoming emails

2010-04-13 Thread Esteban Ignacio Masoero 
Hi:

I think I'm experiencing the same problem. Strangely, I'm sending unicode
(spanish) characters, specially the 'ñ' (spanish N), and I receive them well
in the body part but not in the subject part of the email, where they appear
as a '?'.
I noticed this issue
http://code.google.com/p/googleappengine/issues/detail?id=2288 was created,
but I'm not really sure where it targets my problem.

David, did you finally solve your problem? any ideas about this?

Thanks,

Esteban

Hi there:

I'm facing the same problem. I tried and I tried and I still can't catch any
deadlineException that is supossed to be thrown when I exceed the 30
seconds. The only thing I see is a HardDeadlineExceededError, and in my case
it ocurrs in the middle of a JDOQuery.deletePersistentAll() method.

Anyone has any ideas? All I want to do is make sure that I'm handling that
situation in case it happens. Here's the stack:

com.google.apphosting.runtime.HardDeadlineExceededError: This request
(ccc45fc5ce7541bd) started at 2010/02/12 14:51:12.763 UTC and was still

Hi.
I agree with Kris in that this feature is absolutely necessary. However,
maybe this feature will be included in this other more general issue
http://code.google.com/p/googleappengine/issues/detail?id=217 .
Maybe someone from Google can tell us what's the best way to do it, or
whether we can expect it soon by being included in some other issue.

[appengine-java] Re: Delete without getting, using JDO

2009-11-07 Thread Esteban Ignacio Masoero 
And you can also look here:
http://code.google.com/intl/en/appengine/docs/java/datastore/queriesandindexes.html#Delete_By_Query

To google guys: By the way, there's a typo in the last link of that
paragraph, which doesn't have an anchor.

Jason:

I've created this issue:
http://code.google.com/p/googleappengine/issues/detail?id=2353, so you can
have all the info you need to test both problems.

Thanks again!

[appengine-java] Maximum data size of image sent to service is not 1Mb, but 512Kb?

2009-10-31 Thread Esteban Ignacio Masoero 
Hi there:

I am using the ImagesService as this page (
http://code.google.com/intl/en/appengine/docs/java/images/overview.html )
says, using exactly the code posted there, and found out that with images
between 512Kb (aprox.) and 1Mb, a strange error occurs. Moreover, the
exception thrown does not have the same text description (I asume this in
particular has to do with the differences that still exist between
development and production environment).

Image: .png, 581Kb
Development: Caused by: java.lang.IllegalArgumentException: Failed to read
image at
com.google.appengine.api.images.ImagesServiceImpl.applyTransform(ImagesServiceImpl.java:65)
(...)
Production: Caused by: java.lang.IllegalArgumentException: Unknown at
com.google.appengine.api.images.ImagesServiceImpl.applyTransform(ImagesServiceImpl.java:65)
(...)

This error is different that the one that occurs when an > 1Mb image is
processed, which correctly says "The request to API call images.Transform()
was too large.".

I tried with an .png/466Kb image, and it worked fine in both environments.

I think we have two different issues here, the different error messages in
dev/prod environments, and the apparently real restriction size, which seems
to be < 512Kb aprox.
Has anyone had the same problem? What can google guys say about this?

Thanks in advance,

Esteban

PD = the 581Kb png image was edited with mspaint to reach that size, would
that have something to do with it? (I succesfully visualized in firefox
browser, so think it's ok, but I mention it just in case)

[appengine-java] Re: java.lang.AbstractMethodError at com.google.appengine.tools.development.DevAppServerImpl.getUserPermissions() moving from SDK 1.2.5 to 1.2.6

2009-10-19 Thread Esteban Ignacio Masoero 
If you're not doing junit tests, you should add the VM parameter that
eclipse asks for when editing "running configurations" and that should do.
If you're also doing junit tests, then you should add appengine-agent.jar to
your classpath. There's an issue created about this:
http://code.google.com/p/googleappengine/issues/detail?id=2280
