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.

Add a 'can_be_registered' method that checks before notifying

2014-12-16T03:19:18+00:00

Add a new method that can be used to check if a event type is
allowed to trigger a notification; and initially use it to
disallow the 'ANY' meta event type from being used to trigger
notifications.

Base task executor should provide 'wait_for_any'

2014-12-15T23:52:39+00:00

Instead of having each task executor reproduce the same
code for 'wait_for_any' we can just have the base task
implementation provide the function that everyone is
replicating instead; making common code common and save
the headache caused by the same code being in multiple
places (which is bad for multiple reasons).

Use the notifier type in the task class/module directly

2014-12-14T03:09:03+00:00

Instead of having code that is some what like the notifier
code we already have, but is duplicated and is slightly different
in the task class just move the code that was in the task class (and
doing similar actions) to instead now use a notifier that is directly
contained in the task base class for internal task triggering of
internal task events.

Breaking change: alters the capabilities of the task to process
notifications itself, most actions now must go through the task
notifier property and instead use that (update_progress still exists
as a common utility method, since it's likely the most common type
of notification that will be used).

Removes the following methods from task base class (as they are
no longer needed with a notifier attribute):

- trigger (replaced with notifier.notify)
- autobind (removed, not replaced, can be created by the user
            of taskflow in a simple manner, without requiring
            functionality in taskflow)
- bind (replaced with notifier.register)
- unbind (replaced with notifier.unregister)
- listeners_iter (replaced with notifier.listeners_iter)

Due to this change we can now also correctly proxy back events from
remote tasks to the engine for correct proxying back to the original
task.

Use a tiny clamp helper to clamp the 'on_progress' value

2014-12-14T01:13:07+00:00

Add a misc.clamp function that will clamp a value to a given
range (it can also call a callback if clamping occurs). Use it
to clamp the progress value that was previously clamped with
a set of customized logic that can now be replaced with a more
generalized logic that can be shared.

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.
