[google-appengine] BlobStore - DownloadError: ApplicationError: 2 [Errno 35] Resource temporarily unavailable
In my app, the user uploads one or more files as blobs, then the app takes the blobs, adds BlobReader objects of them to a SOAP request, and sends the request to an external server. I've tested the SOAP request sender outside GAE (using open(filename) instead of BlobReader), and also confirmed that the file uploads to the app correctly. It seems like maybe the error is due to the SOAP request sender being unable to read from the blobstore - does anyone have any idea how I can fix this? Below is the error: INFO 2011-02-09 00:22:14,856 dev_appserver.py:3317] GET /test HTTP/1.1 500 - INFO 2011-02-09 00:22:15,063 dev_appserver.py:3317] GET / favicon.ico HTTP/1.1 200 - WARNING 2011-02-09 00:22:25,498 urlfetch_stub.py:284] Stripped prohibited headers from URLFetch request: ['Content-Length'] ERROR2011-02-09 00:22:25,503 __init__.py:395] ApplicationError: 2 [Errno 35] Resource temporarily unavailable Traceback (most recent call last): File /Applications/GoogleAppEngineLauncher.app/Contents/Resources/ GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/ google/appengine/ext/webapp/__init__.py, line 515, in __call__ handler.get(*groups) File /Users/iratecat/opal/opalapp/handlers.py, line 84, in get res = c.launchJob(cmd_args, blobs) File /Users/iratecat/opal/opalapp/opalclient.py, line 132, in launchJob resp = self.appServicePort.launchJob(req) File ./client/AppService_client.py, line 60, in launchJob response = self.binding.Receive(launchJobResponse.typecode) File ./client/ZSI/client.py, line 547, in Receive self.ReceiveSOAP(**kw) File ./client/ZSI/client.py, line 430, in ReceiveSOAP if not self.IsSOAP(): File ./client/ZSI/client.py, line 422, in IsSOAP self.ReceiveRaw() File ./client/ZSI/client.py, line 389, in ReceiveRaw response = self.h.getresponse() File /Applications/GoogleAppEngineLauncher.app/Contents/Resources/ GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/ google/appengine/dist/httplib.py, line 203, in getresponse self._allow_truncated, self._follow_redirects) File /Applications/GoogleAppEngineLauncher.app/Contents/Resources/ GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/ google/appengine/api/urlfetch.py, line 241, in fetch return rpc.get_result() File /Applications/GoogleAppEngineLauncher.app/Contents/Resources/ GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/ google/appengine/api/apiproxy_stub_map.py, line 530, in get_result return self.__get_result_hook(self) File /Applications/GoogleAppEngineLauncher.app/Contents/Resources/ GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/ google/appengine/api/urlfetch.py, line 325, in _get_fetch_result raise DownloadError(str(err)) DownloadError: ApplicationError: 2 [Errno 35] Resource temporarily unavailable -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Multiple blob uploads in single POST form?
Hi, I want to upload multiple, varying number of blobs with a single POST request. It seems that as of April of last year, this wasn't supported, and someone has posted a JavaScript workaround: http://blog.notdot.net/2010/04/Implementing-a-dropbox-service-with-the-Blobstore-API-part-3-Multiple-upload-support. I couldn't find any information on the official GAE docs as to whether or not this is still the case. Before I dive into the workaround above, could someone confirm that GAE still does not support multiple blob uploads?
