[Unreleased]

[4.2.0] - 2020-08-10

  • Simplify exception capture inside return_handler to avoid unique, unexpected behavior. Remove debug=True cast of unknown exceptions to FailCatastrophically
  • Prevent structlogger from prepending timestamp

[4.1.0] - 2020-07-10

  • Log FailCatastrophically exceptions as they happen instead of all at once
  • Change default parameter passed to functions from event to state

[4.0.3] - 2020-07-10

  • Call exception_handler on FailCatastrophically

[4.0.2] - 2020-07-06

  • Fix bug in tests caused by change of default_kwargs["event"] to namedtuple

[4.0.1] - 2020-07-06

  • format

[4.0.0] - 2020-07-06

  • Allow user of lpipe to process_event with a callable/function and avoid all directed-graph workflow setup
  • Change Payload to split paths into paths and queues. Update all logic to assume only path strings / enums are in payload.paths.
  • Fix bug in get_nested where head could result in incorrectly returne default value
  • Add more documentation

[3.0.3] - 2020-06-15

  • Make 'path' argument optional on the Queue class, and update pipeline.put_record to send kwargs at the root of the message if no path was set.

[3.0.2] - 2020-06-09

  • Added contrib imports to contrib/__init__.py

[3.0.0] - 2020-06-09

  • Reduced code complexity
  • Add type hints
  • Increase test coverage
  • Bugfix: lpipe.sqs.delete_message_batch called boto3 incorrectly
  • Breaking: sentry-sdk no longer a required dependency, install with lpipe = {extras: ["sentry"], version: "*"}, and enable it by setting process_event(exception_handler=lpipe.contrib.sentry.capture)
  • Breaking: moved lpipe.sentry to lpipe.contrib.sentry
  • Breaking: moved lpipe._boto3 to lpipe.contrib.boto3
  • Breaking: removed lpipe.testing, use the boto3-fixtures library instead
  • Breaking: removed lpipe.taxonomy
  • Breaking: renamed LpipeBaseException to LPBaseException (although, you shouldn't use the base class anyways)
  • Breaking: renamed ServerlessLogger to LPLogger
  • Breaking: renamed lpipe.utils._repr to repr
  • Semi-Breaking: moved Action, Payload, and Queue classes into their own modules, but they're still imported into the top level module (i.e. lpipe.Action still works)
  • Deprecated: moved lpipe.utils get_nested, set_nested to lpipe.contrib.mindictive, stubs still in place

[2.0.15] - 2020-05-05

  • To prevent log explosion, stop adding message kwargs by default to logger passed into user's functions.

[2.0.14] - 2020-05-01

  • Set lpipe.testing.awslambda default lambda name to "my_lambda"
  • Fix formatting and linting errors

[2.0.13] - 2020-03-13

  • SQS: If any records fail, delete successful records from the queue before raising an exception.
  • Fix bug in lpipe._boto.proxy where logger was undefined.

[2.0.12] - 2020-03-11

  • If AWS_ENDPOINTS is set with a string as dict ("key=value,key=value") of service names and endpoints, create boto3 clients and resources with the appropriate endpoint_url for a service, if provided.

[2.0.11] - 2020-03-10

  • Add setup/teardown context managers for all AWS testing utils.

[2.0.10] - 2020-03-10

  • Update get_queue_arn() to request QueueArn specifically.

[2.0.9] - 2020-03-10

  • Update SQS testing create utils to create DLQs and redrive policies automatically.

[2.0.8] - 2020-03-10

  • Fix reference to event_source_arn in get_event_source()

[2.0.7] - 2020-03-10

  • Fix bug in utils.get_enum_path() when re-raising an error after catching a KeyError.

[2.0.6] - 2020-03-10

  • Print exception class dynamically when catching TypeError.

[2.0.5] - 2020-03-10

  • Pass entire payload via event rather than just the event_source_arn.

[2.0.4] - 2020-03-10

  • utils.get_nested() now has the option of setting a default value, and it will raise a KeyError if the requested keys don't exist.
  • Unhandled exceptions will now be raised if debug is true.
  • Move event and context into a single dict pased to functions as kwarg event.
  • Pass event source ARN to Payload and, subsequently, to the event dict passed into functions.

[2.0.3] - 2020-03-10

  • Add ability to pass kwargs even if they aren't in the signature

[2.0.2] - 2020-03-10

  • Refactor most tests to just use moto.
  • Add s3 testing helpers

[2.0.1] - 2020-03-05

  • Pass event and context to every function

[2.0.0] - 2020-03-05

  • context is now a required argument of process_event()

[1.2.0] - 2019-10-07
