Spiffworkflow 1.2: Top Level Imports moved to appropriate modules
- replace 'from SpiffWorkflow import WorkflowException' to 'from SpiffWorkflow.exceptions import WorkflowException'
- replace 'from SpiffWorkflow import TaskState' to 'from SpiffWorkflow.task import TaskState'
- replace 'from SpiffWorkflow import Task' to 'from SpiffWorkflow.task import Task'
SpiffWorkflow 1.2: Navigation code removed completely. Proved to be of little use to folks, was super complex and difficult to maintain.
SpiffWorkflow 1.2: When inserting custom functions into the PythonExecutionEngine - be aware that the task data will act as the full context for execution, and will contain global functions and methods during the exec call.
SpiffWorkflow 1.2: All Task Specs now have a spec_type attribute, containing a descriptive string of the type, such as "User Task", "Script Task", "Start Event" etc...
Spiffworkflow 1.2: remove all references of timeit (no longer in SpiffWorkflow)
Spiffworkflow 1.2: pythonScriptEngine._evaluate no longer accepts a task argument.
Spiffworkflow 1.2: CancelEventDefinition was removed - please use SignalEventDefinition instead
EX: replace bpmn_workflow.signal('cancel') # generate a cancel signal.
bpmn_workflow.catch(CancelEventDefinition())
WITH: bpmn_workflow.catch(SignalEventDefinition('cancel'))
Spiffworkflow 1.2: Task States are JUST integers and TaskSpecNames is now a public dictionary, and can be used to covert a state to human readable string
EX: REPLACE: user_task.state.name
WITH: TaskStateNames[user_task.state]
Upraded SpiffWorkflow and now use th new get_subprocess_specs
updated the calculate_stats in the workflow processor - as the serialization had changed drastically, and needed to debug some performance issues.
Added a get_navigation method that will calcuate a basic navigation list MUCH faster than using the get_flat_nav_list in Spiffworkflows Navigation object.
Modified a hellton of tests because we don't have total_task and completed_task counts, or a complex nested navigation list anymore.
Also: All script tasks should raise WorkflowTaskExecExceptions - NOT APIExceptions - this is because our scripts are executed by Spiff (not the other way around) so the errors need to pass fluidly through spiff, and come back to use THEN we can convert them to APIErrors. Otherwise we lose all kinds of good information about the error.
This cleans up the _evaluate method which previously accepted arbitrary args and kwargs, and now requires an expression, a context to which exectute it, and, optionally, the current task being executed if the DMN is being executed as a part of a BusinessRuleTask in a BPMN diagram.
This also cleans up several bits of duplicated code.
There is also a bit of code here to assure that the current user is included when running the master workflow.
it can be kind of irritating for this stuff to be spinning up when you are trying to debug something, so just set
PROCESS_WAITING_TASKS to false in instance/config.py and voila!!
Performance upgrade to study_service.py - Don't query on the whole WorkflowModel, just get the status that we need. Saves lots of complex joins.
Performance upgrade to SpiffWorkflow - don't convert to box unless we have to do so.
Assure we raise more thoughtful error messages when running getting exceptions in engine tasks.
Field Options should always be available now due to a fix in Spiffworkflow.
There was a problem with the python script engine as well that wasn't handling the de-serialize properly and didn't correctly pick back up on the script engine, and the renaming of methods in PythonScriptEngine created some conflicts with the way we override functions.
We were not handling ldap looks up efficiently, and this was also breaking in Study Info.
Finally we had a bug in SpiffWorkflow that did not allow us to reset back to the previous task in some cases where nested call activities happen far later in the process and are currently active when the reset is created.
