Merge "Quote string representations"

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.

Remove six

2022-05-18T07:12:37+00:00

This library no longer supports Python 2, thus usage of six can be
removed. This also removes workaround about pickle library used in
Python 2 only.

Allow for alterations in decider 'area of influence'

Christmas came early.

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).

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.

Add support for conditional execution

2015-07-01T06:04:31+00:00

To make it possible to alter the runtime flow via a simple
conditional like structure make it possible to have the graph
flow link function take a decider that is expected to be some
callable that will decide (via a boolean return) whether the
edge should actually be traversed when running. When a decider
returns false; the affected + successors will be set into the
IGNORE state and they will be exempt from future runtime and
scheduling decisions.

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.

Switch to using 'oslo_utils' vs 'oslo.utils'

2015-01-15T07:56:11+00:00

Prefer the non-deprecated 'oslo_utils' instead of
the namespaced 'oslo.utils' wherever it was previously
used.

Move over to using oslo.utils [reflection, uuidutils]

2014-12-18T21:55:41+00:00

The reflection module is now part of oslo.utils so we should
remove our local version and use that version instead; this
also goes for the uuidutils module which is now part of
oslo.utils as well so we no longer need our local version
copied from the incubator...

Note that one reflection method `find_subclasses` which was to
specific to taskflow is now moved to the misc utility module
instead of its prior home in the reflection module.
