Wallaby Series Release Notes

2.8.2

New Features

  • Redis driver retries actions for up to 15 times when met with error connecting to Redis.

2.7.0

New Features

  • HashRing now accepts a new argument hash_function, allowing using a different hash function.

Bug Fixes

  • Fixes AttributeError in the mysql driver with PyMySQL 0.10.0.

2.4.0

New Features

  • Added support for Consul ACL tokens. Consul ACL tokens can be passed in as a parameterized argument. Requires python-consul2

Upgrade Notes

  • Updated the python-consul library to python-consul2. The original library is no longer maintained while python-consul2 is reasonably maintained. Consul 1.4 has a new ACL implementation, and Consul 1.7 includes some standards enforcement which break python-consul.

2.3.0

New Features

  • The etcd3 and etcd3gw drivers now support TLS, by adding the ability to specify ca_cert, cert_key and cert_cert files. For the etcd3gw driver, this is controlled by specifying “etcd3+https” in the coordination URL.

2.2.0

New Features

  • Added heartbeat supported to the Consul driver so that locks would remain locked instead of timing out on the first TTL. This can be considered both a feature and a bug fix because previously the Consul driver would only hold the lock for the first TTL and behind the scenes Consul would release it due to the lack of session updates. In order for the Consul driver to perform distributed locking properly you MUST utilize heartbeats!

2.0.0

Upgrade Notes

  • Python 2.7 support has been dropped. The minimum version of Python now supported by tooz is Python 3.6.

1.62.0

New Features

  • The etcd3gw driver now supports the group membership API.

1.59.0

New Features

  • The etcd3 driver now supports the group membership API.

1.47.0

New Features

  • Add tooz.hashring, a consistent hash ring implementation.

  • Introduce a new partitioner object. This object is synchronized within a group of nodes and exposes a way to distribute object management across several nodes.

1.45.0

New Features

  • Coordination drivers now have a method join_group_create that is able to create a group before joining it if it does not exist yet.

Other Notes

  • Introduce reno for deployer release notes.
