Send multiple notifications stopped working on AppEngine

[dexity]

About 3 month ago I created development keys for APNs and they worked fine. The notifications were being sent as expected. Recently I created new development and production keys and they stopped working on AppEngine but it still sends messages fine from local script.

Here is how I created the keys:

$ openssl x509 -in aps_production.cer -inform der -out Cert.pem
$ openssl pkcs12 -nocerts -out Key2.pem -in Certificates.p12
$ openssl rsa -in Key2.pem -out Key.pem  # Remove password

It properly connects to production APNs server:

$ openssl s_client -connect gateway.push.apple.com:2195 -cert Cert.pem -key Key.pem

Local script also properly sends messages:

# push.py
import apns

TOKEN_HEX = '24b3703df600427c9444a26e785a4f6642780d0f444ea6e6c279531a748a5511'

app = apns.APNs(use_sandbox=False, cert_file='Cert.pem', key_file='Key.pem', enhanced=True)
# Send a notification
payload = apns.Payload(alert='Hello', sound='default', badge=1)
payload2 = apns.Payload(alert='Hello 2', sound='default', badge=1)
frame = apns.Frame()
frame.add_item(TOKEN_HEX, payload, 1, 3600, 10)
frame.add_item(TOKEN_HEX, payload2, 1, 3600, 10)
app.gateway_server.send_notification_multiple(frame)

I ended up using a single send_notification which works fine on AppEngine but is not efficient as it creates a new connection for every device notification.

import apns
# devices - list of device objects
# kwargs - payload keyword arguments

payload = apns.Payload(**kwargs)
for device in devices:
    apns_socket = apns.APNs(use_sandbox=False, cert_file='Cert.pem', key_file='Key.pem', enhanced=True)
    apns_socket.gateway_server.send_notification(device.device_key, payload)

I can't think of any AppEngine restrictions except may be asynchronous io. I checked the code for apns module and it looks ok. Has anyone experienced the problem?

I'm also having this issue. I'm unable to send the same payload to multiple device tokens.

I just discovered Frame myself, it turns out I was sending each notification one by one all this time

Anyway, #149 fixed the Frame issue for me, haven't tested it on production yet tho
