For a possibly more helpful message, I changed it to:
LOG_INFO(("Password is: %#llx", zh->client_id.passwd));
Here's a failure with that:
ZooKeeper: INFO: check_events@1749: Password is: 0x101883698
kazoo.testing: DEBUG: Password is: c46b53ec5b9290, length: 7
Here we can see that the C layer got a password (not sure on C encoding if
thats 16 bytes or not), and the Python one was 7 characters (prolly 6 chars, it
seems to count one extra). So something is quite wrong here, and of course
supplying the wrong password gets a session expired issue.
If someone that knows C better can translate that password back to the raw
bytes, perhaps it'd be a good test case somewhere to see that the bytes aren't
mucked up someone on the way to Python.
Cheers,
Ben
