Quote string representations

2022-06-10T09:45:32+00:00

networkx 2.8.3 will raise errors if certain characters, such as a colon, in the node names and the string is not quoted.
This patch double quotes flow, node, and task string representations to make sure there are not issues with these characters occuring in the names.

For taskflow patterns don't show taskflow.patterns prefix

2016-01-05T23:38:43+00:00

Showing the full name in flow __str__() isn't expecially
helpful and clutters up graphviz usage and similar so if a taskflow
built-in pattern is stringified just use the short name (that does
not start with taskflow.patterns instead of the full long name).

Fix order of assertEqual for unit.patterns

2015-10-17T08:22:21+00:00

First parameter should be the expected value.

Use graphs as the underlying structure of patterns

2015-09-18T17:39:04+00:00

This unifies all the patterns to be graph based so
that they are more uniform and there underlying constraints
are more easy to understand (taskflow basically processes
graphs).

iter_nodes method added to flows

2015-08-28T14:54:25+00:00

New method allows to iterate over flow node and
get access to node metadata during iteration.

Update Flow::str

2015-02-17T22:18:57+00:00

The current implementation seems a little cryptic so updating it
to clearly indicate the atom count.

Relax the linear flow symbol constraints

2014-09-08T20:55:26+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 linear constraints
and later move those constraint checks and validations
into the engines compilation stage.

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)

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.
