I can crash the dev server when it is running the Blobstore "Complete
Sample App" (
http://code.google.com/appengine/docs/python/blobstore/overview.html#Complete_Sample_App
) by adding a call to images.get_serving_url. Would someone be willing
to try this to see if they also get an error?
To crash the sample app, add these two lines to the end of the
UploadHandler.post() method, just before the redirect:
from google.appengine.api import images
url = images.get_serving_url(blob_info.key())
For what it's worth, I can also crash the sample app by putting these
two lines in the ServerHandler.get() method.
If someone can help me get the images.get_serving_url() function to
"work", I would really appreciate it. I've been dead in the water on
this for days.
