In enhanced mode, connection will enter bad state and stop sending notification after connection idles for more than 2 hours

[jimhorng]

The connection might be broken but the library is not awared, and error-response worker might hang and cause connection not function properly, then, send notification with the same connection will be blocked.

[jimhorng]

fixed by #78

[aabilio]

Could #78 FIX the following error? ->

I have and app (deployed at AWS EB) that is using this project to send push notifications to Apple's devices. It works all okay the first time when I deploy the app, but a while later all notifications stop working and I can't log the problem.. If I redeploy the app again (OR reboot EC2 instance) all works well again the first.. 30 minutes?

I don't know how to log the problem and it's getting me crazy :S

[jimhorng]

@aabilio , I guess the problem is very similar to mine, you may check netstat -ant | grep 2195 to see if connection to apns are gone or not in ESTABLISHED. If so, it's very likely the same cause which can be fixed by this PR #78 .

• You may push reviewer to merge the fix
• or temporarily patch manually
• or use my fork: https://github.com/jimhorng/PyAPNs

[aabilio]

netstat -ant | grep 2195 shows nothing (after this time when the notifications are not working). I going to use your fork to check if solves my problem. Thanks.

[jimhorng]

@aabilio , Great, please kindly let me know if it solved your problem or not, thanks :)

[jimhorng]

@aabilio , any good or bad news on this fix? thanks :)

[aabilio]

I had not had time to try. I hope to try it tomorrow ;)

jimhorng, I pulled your modified code, and it appears to fix this issue. Good job. I believe this should be high priority for a merge. I also hope that the next major version added to pypi happens soon, and includes this change. I look forward to an update on this situation. Thanks again!

[jimhorng]

@jblayney Thanks for your trying, since @djacobs is the owner of this project, could you help to suggest him to merge this #78? Thanks a lot :D

[aabilio]

I just started testing this right now. In a few hours I'll tell you the results ;)

[djacobs]

Thanks.

[jimhorng]

@aabilio may I know your test result, if it passed, then we can close this issue since #78 is merged :)

[aabilio]

I've been testing these days and now it seems that everything works fine

This is in GAE btw.

[jimhorng]

@kelonye As your log shows, you are using enhanced mode with frames, which is NOT currently supported, see #90, there's patch already but not merged to 'master' branch yet.

Thanks mate!
