Change Log

0.9 (WIP)

Improvements

• Add support for setting task priorities. Thanks @paulcollinsiii for PR. #9

0.8 (2016-11-16)

API Changes

• Remove botoflow.retry module in favor of @retry_activity decorator which is much more extensible and is based on retrying library.
• WorkflowStarter is now workflow_starter as context managers should be snake case and it's better to do this now, before 1.0 release.
• Renamed botoflow.workflow_types module to botoflow.flow_types package.
• Removed botoflow.types alias. Use botoflow.flow_types.
• @async is now @coroutine to closer align with asyncio naming. See #1 for details.

Bugfixes

• Fix a critical bug in decider history event ordering, which could affect any workflows that execute activities/child workflows concurrently.
• @activities decorator was ignoring data_converter option. Thanks @glharding.
• Better wrapping of errors from SWF. Thanks @glharding.

Miscellaneous

• It's open sourced!
• doc directory renamed to docs.
• Various package naming fixes.
• Add CONTRIBUTING.rst.
• Add README.rst.
• Lots of work and refactoring in documentation.
• Up to date requirements.txt.
• CircleCI integration.
• Thanks to Gintare Laniauskaite for work on the LOGO and documentation design!
• Add tox support and test CPython 2.7, 3.4 and 3.5.
• Mark some tests in test_async_traceback as xfail for Python 3.5.0 specifically (works fine on 3.5.1).
• Add botoflow.__version__.
• examples directory and helloworld example. Thanks to @l2ol33rt for contribution.

0.7 (2016-04-15)

Improvements

• Add ThrottlingException.
• Do not skip registration for all activities.
• Only try registering unregistered activities.
• Supporting more BaseFuture methods properly.
• json_data_converter - add support for Decimal objects + tests.
• json_data_converter - Make ActivityType serializable in cases where ActivityFailedException is passsed throug SWF.
• json_data_converter - Support datetime and timedelta object serialization.
• Add support for activity retrying using the retrying library as the base with the major difference being that it takes seconds as the smallest resolution as opposed to millis.
• Support handling basic inputs that for example come from on botoflow based workflow starters. See commit 70423b5 for details.

Bugfixes

• Fix a regression in ChildWorkflowExecutionHandler where child workflow exceptions aren't passed to the parent process.
• Make sure that (Any|All)Future s behave wen passed in an empty iterable (they will immediately set an empty result).
• Handle starting a child workflow with a duplicate Workflow ID.

Miscellaneous

• Unit and integration test improvements.
• json_data_converter - Unit test improvements.

0.6 (2015-08-27)

API Changes

• Expose workflow_id and run_id to decision context.
• Initial workflow cancellation support.
  • Add .cancel() method in WorkflowDefinition.
• Add async cancellation_handler method that can be overwritten to do cleanup for workflow cancellation tasks.

Improvements

• Implement workflow cancellation events.
• Big refactor of decider.py into a bunch of specific handlers (ie. activity_task_handler.py, etc.).
• Add separate future for cancel activity.
• Support RequestCancelActivityTaskFailedError.
• ActivityWorker understands Cancellation / CancelledError.
• Implement ActivityFuture that replaces the regular Future for all activities and has SWF support for cancellations.
• Implement request_heartbeat() in Activity context.
• ActivityTaskHandler uses ActivityFuture.

Bugfixes

• Add fallback handling for decoding of exception objects.
• Fix bug in workflow options overrides.
• Added kwarg formatting translation for Child workflow execution trigger.
• Respect pagination token returned in SWF workflow execution history.
• Fixed bug with activities decorator kwargs not falling down to enclosed activity decorators.

Miscellaneous

• Cleanup bogus prints.
• Doctype the async decorator a bit.
• Implement some integration tests.
• delete_decision() now returns True if a decision was deleted successfully and False otherwise.
• Adjust handling of cancel events; parse exception out of event details.
• Cleanup of new handlers and decider.
• More activity cancellation work and more integration tests.
• Logic improvements + integration tests.
• Docstrings all around cancellation work.
• Refactor a bunch of cancellation related tests into a separate test file.

0.5 (2014-10-03)

API Changes

• The worker API now uses botocore session, followed by region, followed by domain, followed by default tasklist.

Miscellaneous

• Use BotoCore 0.66 which has lots of incompatible changes, therefore the worker API changes as well.

0.4 (2014-05-21)

API Changes

• Threading and multiprocessing based workers are renamed "Executor" and accept a worker as an argument so that they can be used with either the normal WorkflowWorker or GenericWorkflowWorker.

New Features

• Add GenericWorkflowWorker which allows specifying a function that can use any method it wants to lookup workflow definitions from a name and version, including by dynamically creating it.

0.3 (2014-04-07)

Improvements

• Include additional attributes when serializing / deserializing subclasses of list and dict.
• Handle (de)serialization of subclasses of list.

Bugfixes

• json_data_converter - base64 encode any string that can't bedecoded as unicode.
• json_data_converter - Make sure we "flowify" dictionary values.
• Fix workflow and activity registration issue where default task list would not be set.

Miscellaneous

• Test that default activity task list is honoured.

0.2 (2013-05-06)

API Changes

• You can use now @async and @async() with the same result.
• As a shortcut: from botoflow import Future.

New Features

• Implement the @workflow decorator. Using this decorator, you can change the workflow name.
• @execute now also accepts data_converter and description parameters. If not specified, the description parameter defaults to the @execute method's docstring, as with @activity.

Improvements

• The metaclass will now look at all bases of a WorkflowDefinition subclass and copy all the @execute and @signal methods to the class we're creating. Subclassing another workflow should now work much better.
• Refactor the data_converter attribute into a property, and add a type check.

Bugfixes

• Create a new event loop on every reset to help with an edge case where gc happens at the wrong moment.

Miscellaneous

• Add a test that tests ability to pass in multiple signals as data into workflow.
• Add a simple workflow subclassing test.
• Add a test that shows multiver works.
• Add a test that tests that @execute method is copied from the superclass to the subclass.

0.1 (2013-04-05)

• Initial release
