Properly handle and skip empty intermediary flows

2014-12-11T04:05:44+00:00

Instead of linking nodes which have elements to
predecessors which do not we should search backwards
through the prior predecessors and link to one that
does have nodes; this ensures that we do not create
bad workflows when empty flows are injected.

Move the _pformat() method to be a classmethod

2014-12-02T01:57:37+00:00

To avoid creating nested functions when a class one
will suffice just switch to using a class method for
the nested _pformat() function instead.

This also makes sure that the cause of a exception is
not none before attempting to format it (and its
children) and also passes along a lines list that is
appended/extended instead of each function call creating
its own version which is later merged.

Remove direct usage of the deprecated failure location

2014-10-21T22:37:44+00:00

Internally we should be using the new location and not the
deprecated location wherever possible. This avoids emitting
warnings messages on our own code, which is a dirty habit.

Switch to a custom NotImplementedError derivative

2014-10-08T22:36:03+00:00

When a feature or method is not implemented it's useful
to throw our own derivative of a NotImplementedError error
so that we can distingush these types of errors vs actual
usage of NotImplementedError which could be thrown from
driver or user code.

Document more function/class/method params

2014-09-26T18:43:45+00:00

To help fill out the docs start adding on docstrings
that document what a parameter is and what its meaning
and usage is to help users better understand the parameter.

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.

Expand documention on failures and wrapped failures types

2014-08-20T00:40:40+00:00

To make it more clear why these objects and types exist and when
and why they are used and reraised increase the verbosity of the
comments and associated inline documentation on these two classes
to help explain there existence & usefulness.
