Patch for exporting an interface to alternative ticket workflows, and a plugin using it
This is a patch against Trac trunk which implements an extension mechanism for allowing alternative ticket work flows. It is discussed at length on PEC under [trac-ticket:869 #869] and NewWorkFlow.
The patch adds two things to Trac's Python API:
- The trac.ticket.api.ITicketWorkflow interface, which abstract the ticket action control logic into an extension point.
- The trac.ticket.field module which is used to describe ticket fields that can be passed to Trac's form_control() Clearsilver function.
It also adds one function to Trac's Clearsilver macros:
- form_control(control). This takes a trac.ticket.field.Field object and renders it as a form control.
Once you have downloaded or checked out the source, apply workflow.diff to Trac trunk and reinstall Trac.
Then change into the tracnewworkflow directory and type:
# python setup.py bdist_egg # cp dist/*.egg /some/trac/env/plugins
Add the following options to your trac.ini in the appropriate sections:
[components] tracnewworkflow.* = enabled [ticket] workflow = tracnewworkflow.tracnewworkflow.newworkflowplugin
Restart your web server.
The plugin implements the following new Trac permissions, which are essentially roles:
Add your users into the appropriate roles using trac-admin and the new ticket workflow should be in place.
Full details on which roles can do what are documented on the NewWorkFlow page.
It is entirely possible that I have not captured all of the transitions correctly, and there are some known outstanding issues.
If you have any issues, create a new ticket.

Modified workflow logic to be independent of TICKET_* permissions. It relies solely on the ROLE_* now.
