Issue "AttributeError: NoneType' object has no attribute 'sendall'" is closed?

[Ali Bozorgkhan]

Hi,

Sometimes I get "AttributeError: NoneType' object has no attribute 'sendall'" error. I googled it and found this issue on github: https://github.com/pika/pika/issues/518.

The issue is closed and referenced in https://github.com/anchor/ceilometer-publisher-zeromq/issues/8. I don't see any connections between pika and ceilometer-publisher-zeromq. Am I missing something? Is there a fix for the error?

Cheers,

Ali

This pika BlockingConnection issue should be addressed in pika master branch already.

There were several PRs that addressed consistency issues in BlockingConnection related to the ConnectionClosed exception. However, the reason that you might be getting "AttributeError: NoneType' object has no attribute 'sendall'" could also be user error: if - after ConnectionClosed - you call any methods that need to perform I/O on the connection, you will get exceptions like the one that you are seeing.
