Re: [appengine-java] BlobStore Image Service

2010-11-04 Thread Jeremy Blythe

I do this in my app. I've written a blog entry with examples here:

I know about the new super-fast image serving API for images stored in
the blobstore - it's awesome and greatly simplifies image resizing..

However I still want to resize the original image to a smaller size
before handling it with the image serving API.. So if a user uploads a
5MB Image I want to resize it say to 1000x1000 and then serve using
the Image Service.

My question is how to resize an image from blobstore and put it back
to blobstore after the resize? The resize API returns the modified
image as a byte array, but can somebody provide an example of how to
put that byte array back into the blobstore? I know we are supposed to
POST it to blobstore, but i couldn't get this thing to work - while
handling the POST for original upload, I transform the Image and
supposed to Invoke yet another POST? An working example would be
great!

Thanks!

[appengine-java] Extend UrlFetch timeout on development server?

2010-11-04 Thread Philippe Beaudoin

I'm trying to use the UrlFetch API to test my Paypal integration on the
development server. When I send a badly formatted request I quickly get
an error reponse from Paypal's sandbox server. However, as soon as I
issue a valid request, it takes too long to process and I get a timeout
error.


I have tried both with the java.net API and the low-level URLfetch API,
in both cases extending the deadline to 10s via
URLConnection.setConnectTimeout(1) and/or
request.getFetchOptions().setDeadline(10d);


It seems this is not enough, however, as I keep getting:
[WARN] /testpaypal.do: java.io.IOException: Timeout while fetching:
https://api-3t.sandbox.paypal.com/nvp



1) It looks like the timeout occurs well before 10s have elapsed

2) I hear the Paypal sandbox server is slower than the production server
3) I bet my personal internet connection is slower than AppEngine's
4) I just want to test, I don't care about AppEngine's timeout for now


For all these reasons, I'd love to be able to extend the URLFetch
timeout on the development server to more than 10s -- in fact, just
extending it to a real 10s would already be great.


Any idea on how to do that? Or how to test that efficiently?


Anybody has had success integrating with PayPal on App Engine?

Re: [appengine-java] Re: 1.3.8 Console Logging Issue

I changed the GWT log level to TRACE solving partially the problem, infact

Re: [appengine-java] Mapper Blobstore bytes read limit

2010-11-04 Thread Cyrille Vincey

Not a lot of interesting stuff to say :
1. My code is quite as simple as your sample code: the only real difference
is that I create 2 parent/child entities in a row for one given csv line
entry.
2. My csv file contains 4.3 million lines.
2. I launched the mapper job with 10 shards.
3. worker-attempt-XXX tasks had 20 retries each in average.
4. The blobstore bytes read quota (100 Go) got reached within the first 3
hours.
5. Est. 10% of the entities where actually created after 24h (with my
previous non-blob-based mapper job, those 4.3 million entities where created
within 1 day)
6. Log does not reveal anything interesting.

I am currently running a new test with a 500,000 lines csv file (20 Mb
file).
Performance looks better. To me, blob file size may have an influence on the
mapper performance.

If you need more details, let me know.

This behavior doesn't seem right. No, the entire blob should not be getting
read. We'll look into this.

Do you have any more details? Could tasks be getting retried?

 I've been testing Ikai's bulkload mapper (see url below) with a pretty big csv

 It works great, and I encourage most of you to consider implementing this for
 entity uploads.
 
 Yet, I do face one last issue with an unexpected quota : blobstore bytes read.
 This quota cannot be tuned via the billing settings, and it's not clear
 whether it limits the speed of my process or not when it's reached.
 
 
 See ? Yep, it's a lot of bytes readŠ
 Could someone confirm that the blob csv file is *NOT* fully fetched each time
 the mapper iterates on a new line ?

2010-11-04 Thread Didier Durand

Hi Ip,

do you correctly initiate your local env for the datastore: see
http://code.google.com/appengine/docs/java/tools/localunittesting.html#Writing_Datastore_Tests

You should then get an active transaction when needed. Let me know if
needed: can provide you with my own code when needed

regards

didier

Re: [appengine-java] Re: 1.3.8 Console Logging Issue

2010-11-04 Thread Rajeev Dayal

We're going to fix this for the App Engine 1.4.0 release. What we'll do is
have messages at Log.INFO level be outputted when you've got your Launch
Configuration's log level set to INFO.

In the Google Plugin for Eclipse, we'll make a change such that any new
launch configurations created have a default log level of WARN.
