0.5 (2012-09-06)
Skipping a version to reflect the magnitude of the change. Kazoo is now a pure
Python client with no C bindings. This release should run without a problem
on alternate Python implementations such as PyPy and Jython. Porting to Python
3 in the future should also be much easier.
Documentation
- Docs have been restructured to handle the new classes and locations of the
methods from the pure Python refactor.
Bug Handling
This change may introduce new bugs, however there is no longer the possibility
of a complete Python segfault due to errors in the C library and/or the C
binding.
- Possible segfaults from the C lib are gone.
- Password mangling due to the C lib is gone.
- The party recipes didn’t set their participating flag to False after
leaving.
Features
- New client.command and client.server_version API, exposing Zookeeper’s
four letter commands and giving access to structured version information.
- Added ‘include_data’ option for get_children to include the node’s Stat
object.
- Substantial increase in logging data with debug mode. All correspondence with
the Zookeeper server can now be seen to help in debugging.
API Changes
- The testing helpers have been moved from testing.__init__ into a
testing.harness module. The official API’s of KazooTestCase and
KazooTestHarness can still be directly imported from testing.
- The kazoo.handlers.util module was removed.
- Backwards compatible exception class aliases are provided for now in kazoo
exceptions for the prior C exception names.
- Unicode strings now work fine for node names and are properly converted to
and from unicode objects.
- The data value argument for the create and create_async methods of the
client was made optional and defaults to an empty byte string. The data
value must be a byte string. Unicode values are no longer allowed and
will raise a TypeError.
