[Openflow-dev] Auto pushing in OF

[Daniele T. <d.t...@ic...>]

BEFORE:

OpenFlow had two policies for assigning work: pull and push. "Pull" means=
=20
users will fetch workitems from a pool of unassigned workitems. "Push"=20
implies that a user could manually assign a workitem to another user.

You could see these policies as "pull" and "manual push", since the pushi=
ng=20
had to be done manually by some user.


NOW:

I just updated the CVS so that another assignment policy could be used: "=
AUTO=20
PUSH", meaning that OpenFlow will automatically assign the workitem to a =
user=20
when the workitem arrives in the activity. The assignment will be done=20
invoking an application (declared in OF as usual) that should return an u=
ser=20
name. To the application will be passed a "possible_users" parameter=20
reporting a list of user names enabled to start that activity application=
=2E

Since older versions of OpenFlow will crash using this new version, you c=
an=20
use an automatic updating function callable by the 'Management' tab of=20
OpenFlow. Just go to the URL "http://yourZope.site/whereverOFis/Managemen=
t"
and click on the update button. All the activities in all processes will =
get=20
a "manual push" setting.

As usual, comments and questions are appreciated.
