Relax the graph flow symbol constraints

2014-09-08T20:55:45+00:00

In order to make it possible to have a symbol
tree we need to relax the constraints that are
being imposed by the graph flow.

Relax the unordered flow symbol constraints

2014-09-08T20:55:41+00:00

In order to make it possible to have a symbol
tree we need to relax and remove the constraints
that are being imposed by the unordered constraints
and later move those constraint checks and validations
into the engines compilation stage.

Relax the linear flow symbol constraints

In order to make it possible to have a symbol
tree we need to relax and remove the constraints
that are being imposed by the linear constraints
and later move those constraint checks and validations

Enabled hacking checks H305 and H307

2014-07-17T07:05:48+00:00

* H305  imports not grouped correctly
* H307  like imports should be grouped together

Adjust the exception hierachy

2014-03-25T03:42:30+00:00

Group the exceptions into the following groups
  * Storage
  * Jobs
  * Execution
  * Other (wrapped failure here)

This grouping makes it easier to understand where
one type of exception should be used vs using another
type of exception.

Backwards incompatible changes:
  * StorageError -> StorageFailure
  * AlreadyExists -> Duplicate
  * WrappedFailure now inherits from Exception
    and not directly from TaskFlowException since it
    wraps arbitrary other exceptions and is not
    specific to taskflow.

Cleanups:
  * JobNotFound -> NotFound
  * EmptyFlow -> Empty
  * JobAlreadyExists -> AlreadyExists
  * InvariantViolation (X)
  * ConnectionFailure (X)

Rework graph flow unit tests

2014-03-22T15:22:00+00:00

This commit adds unit tests that check graph flow methods without
executing or flattening it. Now-redundant tests from other test
suites are deleted.

Unit tests for unordered flow

2014-03-21T11:26:01+00:00

This change adds unit tests that check unordered flow methods
without loading it into engine and executing it.

Linear flow: mark links and rework unit tests

2014-03-21T10:26:24+00:00

- add 'invariant': True to all links produced by linear flow;
- write new unit tests for basic functionality of linear flow
  pattern;
- remove some simple now-redundant unit tests from
  test_flow_dependencies.
