Split revert/execute missing args messages

2016-05-26T22:07:03+00:00

To make it more obvious when a revert method is missing
a dependency, we now identify which method was missing
the required paramater.

Use encodeutils for exception -> string function

2015-07-01T00:08:45+00:00

The oslo.utils library now provides a better version of
this that always returns a unicode exception message, so
update our usage to use it (and remove our own local
function). This guarantee of unicode also means we have to
update a few other places to make sure we get back bytes
or unicode as needed.

Avoid going into causes of non-taskflow exceptions

Make an attempt at having taskflow exceptions print causes better

2015-03-31T18:25:35+00:00

It is often quite useful to try to see what the contained causes
are on versions of python that do not have the native support for
this built-in so to make everyones life easier add basic support
for traversing the cause list and printing out associated causes
when we are able to.

Chain exceptions correctly on py3.x

2015-02-20T18:36:55+00:00

In order to chain exceptions add a helper that can
be used to chain exceptions automatically (when able)
and use it in the various places we are already creating
a new exception with a prior cause so that on py3.x the
newly created exception has its 'cause' associated using
the syntax available to do chaining in py3.x (which formats
nicely as well in that python version).

Fix log statement

2015-02-13T23:48:06+00:00

Added quotes around flow repr output used in exception.  Since
the name can contain spaces it maybe sometimes confusing to debug
without the quotes.
