Changelog

0.2b1 (7/27/2012)

Bug Handling

• ZOOKEEPER-1318: SystemError is caught and rethrown as the proper invalid state exception in older zookeeper python bindings where this issue is still valid.

• ZOOKEEPER-1431: Install the latest zc-zookeeper-static library or use the packaged ubuntu one for ubuntu 12.04 or later.

• ZOOKEEPER-553: State handling isn’t checked via this method, we track it in a simpler manner with the watcher to ensure we know the right state.

Features

• Exponential backoff with jitter for retrying commands.

• Gevent 0.13 and 1.0b support.

• Lock, Party, SetPartitioner, and Election recipe implementations.

• Data and Children watching API’s.

• State transition handling with listener registering to handle session state changes (choose to fatal the app on session expiration, etc.)

• Zookeeper logging stream redirected into Python logging channel under the name ‘Zookeeper’.

• Base client library with handler support for threading and gevent async environments.
