[appengine-java] Re: How to debug blobstore uploads with 405
Answered my own question... I was redirecting to a bad success url, which didn't support POST. Not the most informative error, but still understandable. On Aug 27, 12:58 pm, tempy fay...@gmail.com wrote: Hello all, I am trying to upload to the blobstore from an installed c# client, not a browser. So far, I've only tried the development server... I can see in the datastore viewer that the blobs are being correctly created because there are corresponding blobinfo objects that correctly reflect the uploaded data, but my client gets a 405 response from the blobstore and my success url never gets invoked. How does one go about debugging this? I don't see any kind of output from the blobstore on the eclipse console, so I'm not sure where to start.

[appengine-java] Re: problem using limits and offsets with App Engine Low Level API
I read that pagination has an unpublished limit of 2000. Anyone know
it that's still true? Seems to be the case in my testing.. This
breaks my app? Can anyone help?

Hi,
I'm attempting to iterate through a large number of entities (3000)
using limits and offsets. On the first pass my limit is 500 and my
offset is 0. I get 500 results.
On the second pass with limit 500 and offset 500, I get 500 results.
This approach seems to work ok until I get to limit 500 with offset
1500. On that pass, I get 1000 results, which seems pretty strange
given I set a limit of 500.
Code Snippet:
DatastoreService ds = DatastoreServiceFactory.getDatastoreService();
IterableEntity results = (IterableEntity)
ds.prepare(query).asIterable(withLimit(500).offset(1500));
for (Entity result : results){
Any input would be appreciated.
Thanks,

[google-appengine] OAuth integration issue with Google Apps
I am having trouble accessing protected resources through OAuth. I have an AppEngine application (services-systemical) registered through my Google Apps domain (systemical.com), a CNAME pointing to my application (services.systemical.com , working perfectly with my other non-Oauth services). I have registered my application and got the consumer key and consumer secret for services.systemical.com. With my desktop client application (I am using Leah Culver's oauth v1.0a python library on the client side): I am able to get a request token, have the user authorize the application, upgrade the token to an access token (with the verification code). Now the issue is: when I make an OAuth HTTP POST (body containing the request data) AppEngine always raises an oauth.OAuthRequestError. I am not doing anything fancy for starters: class EndPoint(webapp.RequestHandler): def post(self, fragment): body=self.request.body headers=self.request.headers try: user = oauth.get_current_user() logging.info(EndPoint.post: fragment(%s) data=%s % (fragment, body)) except oauth.OAuthRequestError, e: logging.info(EndPoint.post: headers: %s % headers) logging.info(EndPoint.post: body: %s % body) What step could I be missing?

I failed miserably, then now I found this: The one exception to this is applications which do hybrid OpenID/ OAuth — whitelisting does not currently work with this approach.

Matt, even if that's the case, it'd be nice if the delay of dozens of get_serving_url() API calls could be parallelised and not added up sequentially (which is what I was trying to find out in my long-winded question to Ikai).
