History

0.14

• Provide an option to control requirements checking when loading plugins, and disable it by default. This removes protection against loading the wrong version of a plugin, or that plugin’s dependencies.

0.13

• Deprecate TestExtensionManager and replace with make_test_instance() class method to provide test classes that behave more like the production class, while still allowing the extensions to be injected for testing. (contributed by drocco-007)
• Include a work-around to avoid a cpython bug with atexit (#15881). (contributed by philiptzou)
• Update documentation to refer to setuptools instead of distribute. (contributed by westurner)
• Add pypy to the list of default test configurations.

0.12

• Fixes an exception when reporting on an error where multiple drivers have the same name (issue 25, solution provided by clayg).
• Switch packaging to use pbr.
• Add map_method() API to controllers.

0.11

• Fixes logging configuration under Python 2.6 with a NullHandler. (issue 2)

0.10

• Adds propagate_map_exceptions parameter to all of the extension managers which specifies whether exceptions are propagated up through the map call or logged and then ignored. The default is to preserve the current behavior of logging and ignoring exceptions. Christopher Yeoh <cyeoh@au1.ibm.com>

0.9

• Add name_order parameter to NamedExtensionManager to coerce map() into processing the extensions in the order they are named when the manager is created, instead of the random order they may have been loaded. Contributed by Daniel Rocco.
• Change the NamedDispatchExtensionManager to ignore missing extensions (issue 14).
• Add __getitem__ to ExtensionManager for looking up individual plugins by name (issue 15).
• Start working on the tutorial, Using Stevedore in Your Application.
• Remove dependency on distribute, now that it is merged back into setuptools 0.7 (issue 19).

0.8

• Ignore AssertionError exceptions generated when plugins are loaded.
• Update NamedExtensionManager to check the name of a plugin before loading its code to avoid importing anything we are not going to use.

0.7.2

• Fix logging support for Python 2.6.

0.7.1

• Fix an issue with logging configuration.

0.7

• Add memoization to the entrypoint scanning code in ExtensionManager to avoid performance issues in situations where lots of managers are instantiated with the same namespace argument.

0.6

• Change the EnabledExtensionManager to load the extension before calling the check function so the plugin can be asked if it should be enabled.

0.5

• Add TestExtensionManager for writing tests for classes that use extension managers.

0.4

• Removed the name argument to plugin constructors.
• Added driver property to DriverManager.

0.3

• Added dispatch managers for selecting among a set of plugins at runtime instead of load time.
• Added __call__ method to DriverManager so it can be invoked in a more natural fashion for a single plugin.

0.2

• Added documentation

0.1

• First public release
