A powerful workflow engine implemented in pure Python

SpiffWorkflow

Spiff Workflow is a workflow engine implemented in pure Python. It is based on the excellent work of the Workflow Patterns initiative. In 2020 and 2021, extensive support was added for BPMN / DMN processing.

Motivation

We created SpiffWorkflow to support the development of low-code business applications in Python. Using BPMN will allow non-developers to describe complex workflow processes in a visual diagram, coupled with a powerful python script engine that works seamlessly within the diagrams. SpiffWorkflow can parse these diagrams and execute them. The ability for businesses to create clear, coherent diagrams that drive an application has far reaching potential. While multiple tools exist for doing this in Java, we believe that wide adoption of the Python Language, and it's ease of use, create a winning strategy for building Low-Code applications.

Build status

Code style

Dependencies

We've worked to minimize external dependencies. We rely on lxml for parsing XML Documents, and that's it! Built with

• lxml

Features

• BPMN - support for parsing BPMN diagrams, including the more complex components, like pools and lanes, multi-instance tasks, sub-workflows, timer events, signals, messages, boudary events and looping.
• DMN - We have a baseline implementation of DMN that is well integrated with our Python Execution Engine.
• Python Workflows - We've retained support for building workflows directly in code, or running workflows based on a internal json data structure.

A complete list of the latest features is available with our release notes for version 1.0.

Code Examples and Documentation

Credits and Thanks

Samuel Abels (@knipknap) for creating SpiffWorkflow and maintaining it for over a decade.

Matthew Hampton (@matthewhampton) for his initial contributions around BPMN parsing and execution.

The University of Virginia for allowing us to take on the mammoth task of building a general-purpose workflow system for BPMN, and allowing us to contribute that back to the open source community. In particular, we would like to thank Ron Hutchins, for his trust and support. Without him our efforts would not be possible.

Bruce Silver, the author of BPMN Quick and Easy Using Method and Style, whose work we referenced extensively as we made implementation decisions and educated ourselves on the BPMN and DMN standards.

The BPMN.js library, without which we would not have the tools to effectively build out our models, embed an editor in our application, and pull this mad mess together.

Kelly McDonald (@w4kpm) who dove deeper into the core of SpiffWorkflow than anyone else, and was instrumental in helping us get some of these major enhancements working correctly.

Thanks also to the many contributions from our community. Large and small. From Ziad (@ziadsawalha) in the early days to Elizabeth (@essweine) more recently. It is good to be a part of this long lived and strong community.

spiffworkflow's Issues

Timer events or Tasks

I am struggling to find documentation on how to use timer events and/ or tasks. I need them for escalations and notifications when users do not act within a certain time period to tasks.

Where can I find directions on how this works, or pointers on how to implement such behaviour.

Documentation issue

Here http://spiffworkflow.readthedocs.io/en/latest/tutorial/index.html, in the json, the president task

"president": {
            "class": "SpiffWorkflow.specs.ExclusiveChoice.ExclusiveChoice",
            "name": "president",
            "manual": true,
            "inputs": [
                "general"
            ],
            "outputs": [
                "workflow_aborted",
                "nuclear_strike"
            ],
            "choice": null,
            "default_task_spec": "workflow_aborted",
            "cond_task_specs": [
                [
                    [
                        "SpiffWorkflow.operators.Equal",
                        [
                            [
                                "Attrib",
                                "confirmation"
                            ],
                            [
                                "value",
                                "yes"
                            ]
                        ]
                    ],
                    "president"
                ]
            ]
        }

Here in the output task if the condition is true, president is given. I think it should be nuclear_strike.

enforce 80 character lines (pep8?)

pep8 goes for 80 character lines, but I noticed some files have much longer lines, in particular some of the BPMN stuff. Would it be okay to enforce 80 character lines throughout the codebase?

Support for ServiceTask ?

Hello !

I noticed there was an implementation of ServiceTask in the forked version for ZEngine : https://github.com/zetaops/SpiffWorkflow/blob/master/SpiffWorkflow/bpmn/specs/ServiceTask.py

As I'm using the original repository for its LGPL 3 license, I was wondering if there is any plan to backport this class. I'm indeed a little bit confused by the LGPL 2.1 licence mentionned in the class file header...

BMPN modeler

Hello! Which GUI BPMN editor can I use to load to the SpiffWorkflow? Bizagi Modeler 2.6 saves xml not compatible with the SpiffWorkflow/

Can i save a running workflow instance?

In the event if a task is waiting for a response from human, can the running workflow be saved and resumed only after the task has been executed? I don't see any doc on that or i must have missed it?

bug in ThreadSplit _find_my_task?

In ThreadSplit.py, in _find_my_task there is a reference to my_task that doesn't seem to exist. It's used by _on_trigger, which would then seem to have to fail with a NameError. What's going on here?

Documentation on XML for bpmn

Hi Guys,
We are trying to implement SpiffWorkflow in an exiting new project. However the documentation of the XML lacks examples and the examples I do find do not work

According to the documentation (and examples I found) the following should work:

with open(flow_def, 'r') as xmlflow: 
    xml_data = xmlflow.read() 
    spec = WorkflowSpec.deserialize(XmlSerializer(), xml_data, filename=flow_def)

However using this code results in an

    E       AttributeError: 'str' object has no attribute 'findtext'

Looking at the statement that is executed, this can never work because it expects an lxml object.

How to custmize task by following bpmn 2.0?

I am going to implement workflow by following bpmn 2.0
but I don't know how to customize task which can execute job what I want
which task should I override, scriptTask or callActivity or ....?
I am not sure how to implement is correct way
Would you please help me?
Thank you so much

wireit

In the folder wireit you forgot to put the build folder.

Why not follow the "Style Guild for Python Code"(PEP 8)

Thank U for ur job.
When i'm reading ur codes, i was confused the code style, such as:

        nodetype        = start_node.nodeName.lower()
        name            = start_node.getAttribute('name').lower()
        context         = start_node.getAttribute('context').lower()
        mutex           = start_node.getAttribute('mutex').lower()
        cancel          = start_node.getAttribute('cancel').lower()
        success         = start_node.getAttribute('success').lower()
        times           = start_node.getAttribute('times').lower()
        times_field     = start_node.getAttribute('times-field').lower()
        threshold       = start_node.getAttribute('threshold').lower()
        threshold_field = start_node.getAttribute('threshold-field').lower()
        file            = start_node.getAttribute('file').lower()
        file_field      = start_node.getAttribute('file-field').lower()

see http://www.python.org/dev/peps/pep-0008/#id16

and

type(context) != type([])

just use

isinstance(context, list)

and

_spec_map.has_key(child_node.nodeName.lower()):

just use

child_node.nodeName.lower() in _spec_map

.
Thank U.

JSON Encoder blames "TypeError: UUID('871648c3-4a1b-4939-8136-3323cde73744') is not JSON serializable"

In Task.py line 176: self.id = uuid4()
uuid4() returns a UUID('871648c3-4a1b-4939-8136-3323cde73744') which is not JSON serializable.

Is it possible to update data in the middle?

I am quite confused that as for the example of nuclear strike, how to modify attribute confirmation when task is processing?

Equal Operator didn't work properly as _matches() method always return True.

cond = Equal(Attrib('test_attribute1'), Attrib('test_attribute2'))

cond._matches(my_task) always return True which should be False in this case.

Use base64 for serialization instead of UU

I came across a bug in the serialization code (max 45 bytes for https://github.com/knipknap/SpiffWorkflow/blob/master/SpiffWorkflow/storage/DictionarySerializer.py#L15) and as I was researching it I came across this article: http://effbot.org/librarybook/uu.htm. It suggests the UU is deprecated in favor of base64 encoding.

While I implemented a temporary fix in #10, I did not want to replace the serialization code until I got further input and also get a sense for how many people might be using SpiffWorkflow and how much backwards compatibility do we need to build in.

BPMN engine documentation

I recently added a ton of documentation for most parts of SpiffWorkflow (and ported the module to Py3). The only missing part is documentation for the BPMN layer, which I am now trying to add.

@matthewhampton can you help out with the following questions?:

• What is the purpose of the BpmnWorkflow.accept_message() method?
• Do you have a minimal example of how to run a BPMN workflow?
• Why did you add BpmnWorkflow.do_engine_steps() in addition to the already inherited BpmnWorkflow.complete_all()? Is this actually needed?

Crash while compiling with cxFreeze, Py2Exe and PyInstaller

When compiling an application that uses SpiffWorkflow into an exe the resulting exe crashes with "ImportError: No module named UserList"

The result is the same for all 3 tools to compile the application.

I have traced this back to the statements in the Packager under BPMN:

from future import standard_library standard_library.install_aliases()

As far as I understand this is only needed to allow configparser to be found in Python2 and 3. However, in the last version of 2.7 this has been taken care of. So I wonder if these lines can be safely removed?

Are Input/Output parameters supported?

Hi,

I am wondering if input/output parameters are supported (I am using Camunda Modeler).

I successfully used an Script Task which does "task.set_data(found='yes')" and then I have an exclusive block that has two outgoing things with expressions: "found=='yes'" and "found!='yes'".

But can't be this done this using input/output parameters. What is a use case for this?

Is this project still supported or commercially supported?

I also notice https://procedure8.com/, the commercial supporter returns 502 (30/04/2019)

doc/tutorial/deserialize.py is failing

After doc/tutorial/deserialize.py was executed, I run deserialize.py

Traceback (most recent call last):
File "deserialize.py", line 8, in
spec = WorkflowSpec.deserialize(serializer, workflow_json, 'nuclear.json')
TypeError: deserialize() takes 3 positional arguments but 4 were given

Documentation states BPMN supports Inclusive Gateways but it doesn't?

When trying to use an inclusive gateway with two outgoing sequence flows I get this error.

SpiffWorkflow.bpmn.parser.ValidationException.ValidationException: Multiple outgoing flows are not supported for tasks of type
Source Details: bpmn:inclusiveGateway

Are we expected to subclass 'handles_multiple_outgoing' to get this working?

ImportError: No module named SpiffSignal

Hi all,

I would like to try this lib but obviously its not working. When I simply to in python:

from SpiffWorkflow import Workflow

I get the error:

Traceback (most recent call last):
File "", line 1, in
File "/usr/local/lib/python2.7/dist-packages/SpiffWorkflow/init.py", line 1, in

from TaskSpec import TaskSpec
File "/usr/local/lib/python2.7/dist-packages/SpiffWorkflow/Tasks/TaskSpec.py", line 16, in
from SpiffSignal import Trackable
ImportError: No module named SpiffSignal

Obviously a module is missing. I was not able to find it into the install directory.
Any clew why it disappeared?

Cheers

Join can't be write by hand to JSON

Hello, deserializer expected treshold serialized by pickle and to base64. So this is something which is nearly impossible write by hand, only possibility is to generate this node by serialization.

Should 'specs.Assign' really be in specs?

Should it be in operators.py or in the root? It's not really a spec. I came across it trying to figure out how pre/post_assign work...

Error handling

When an error occurs in a scripttask the workflow is aborted. Is there a more subtle way to handle exceptions within Spiff?

Run all non manual tasks

From the tutorial:

# Execute until all tasks are done or require manual intervention.
 +workflow.complete_all()

This will run all tasks using default choices not respecting task spec definitions flagged as manual. How does one "require manual intervention"?

Make a release on PyPi

The latest release on PyPi was 0.3.0 in 2009. The code has changed a fair amount since then. It's time for a new version number - 1.0 maybe? - and a new release.

设备报修管理的审批工作流程，是否适用于SpiffWorkflow

有以下应用场景：
1、用户有设备需要报修，填写了设备缺陷信息。提交给设备管理部门
2、设备管理部门获取缺陷信息后，评估缺陷，并填写预估费用，提交给部门领导审批。
3、领导审批后，技术人员组织维修设备，并反馈维修结果。
4、用户获取维修结果反馈，验收设备，并给出评价。

DictionarySerializer._(de)serialize_sub_workflow handles in|out_assign as dict instead of list

does SpiffWorkflow supports LDAP?

Question on Duplicate Task IDs

I've come a cross a few situations where I have ended up with duplicate task IDs. I noticed in the code that there are places where you account for that (like in workflow.get_task()).

What are the legitimate cases where you have tasks with the same IDs?

How to Run SpiffWorkFlow Using Python?

Iam Using Linux Operating System to Run the project..So help me to run the project using command based

exclusive-choice conditional-successor successor is join run empty task

After run test code, I want get current task collect_change, but now is empty!

Fix simple typo: storred -> stored

There is a small typo in SpiffWorkflow/specs/Celery.py.
Should read stored rather than storred.

TaskSpec refactoring

Some refactoring of the TaskSpec classes seems to be in order:

• Is TaskSpec._predict_hook required? Does a simpler alternative exist?
• Stop interpreting the return value of hook functions, it makes things hard to understand.
• Predicted states should ONLY be set within the predict() method, nowhere else.
• The TRIGGERED state should be an extra flag instead of part of the state value.
• my_task._inherit_attributes() in TaskSpec should be called in Task if it is not TaskSpec-specific.
• Are the other hook methods all needed?
• Can Task._update_children be split into _update_children and _update_child_state?

bare Excepts can catch Exception instead?

Is it really necessary to have bare except statements in the codebase or could be replace them with catching Exception? They wouldn't catch KeyboardInterrupt that way, but that's a rather unusual case anyway.

can copyright modify the Apache 2.0 license? Thank you very much!

Comparing pickles in tests depends on implementation-specific details and is unreliable

For fun I ran the test suite on PyPy. It all works, up till the point where it compares two pickles:

Exception: task_specs/go_to_repetition/pre_assign/[0]/Unequal: 'gAJjU3BpZmZXb3JrZmxvdy5vcGVyYXRvcnMKQXNzaWduCnEAKYFxAX1xAihVBXJpZ2h0cQNYAQAAADBxBFUPcmlnaHRfYXR0cmlidXRlcQVOVQ5sZWZ0X2F0dHJpYnV0ZXEGWAYAAAByZXBlYXRxB3ViLg==' vs 'gAJjU3BpZmZXb3JrZmxvdy5vcGVyYXRvcnMKQXNzaWduCnEAKYFxAX1xAihVDmxlZnRfYXR0cmlidXRlcQNYBgAAAHJlcGVhdHEEVQVyaWdodHEFWAEAAAAwcQZVD3JpZ2h0X2F0dHJpYnV0ZXEHTnViLg=='

If you base64 decode the string, you see that the pickles are the same, just that they have keys in a different order.

I initially thought this was a PyPy bug and reported it: https://bugs.pypy.org/issue1693
However, it turns out that even in regular python it's not safe to rely on the ordering.

I'm not sure what the best way to fix this is.

• At DigiACTive we're trying to move away from pickles entirely - see the PureDictionarySerializer branch (it's not quite ready for a pull request yet but I'll get there eventually) - one option would be to go with that and just do away with comparing pickles entirely.
• Another option is to rewrite the tests to unpickle the objects and compare them - that would require writing some __eq__ functions for Assign, etc.

I don't understand the rationale for pickling things, so I'd lean towards the first solution, but I'm fully open to being convinced about the necessity of pickles.

Terminology "properties" and "attributes" is confusing

We should rename SpiffWorkflow properties and SpiffWorkflow attributes, and the related methods, to "task_data" and "task_spec_data", to avoid confusion with their Python equivalents.

doubt on tasks

Hello,
How would one connect a python function to a task, for example in workflow1.py?
Or how would one get the task to do some processing ?

CompactWorkflowSerializer incorrectly deserializes state of Parallel Gateway

I have a simple BPMN 2.0 workflow with a parallel split, two tasks running in parallel and a join - see attached.

I progress my workflow to a state where both tasks are complete, and my Join Parallel Gateway is set to READY state.

If I serialize the workflow at this stage and then deserialize it back, CompactWorkflowSerializer sets the state of the Join Parallel Gateway to WAITING.

I am attaching a BPMN 2.0 diagram and a code snippet that can be used to reproduce the issue.

Some errors while running test suite on Windows

tests/SpiffWorkflow/run_suite.py, line 72 also needed fixing:

DMN support

Hi,

this library does not have a dmn engine (http://demo.bpmn.io/dmn or https://camunda.org/dmn/simulator/) right?

I searched a lot and there is not dmn decoder/engine for python... Am I missing something?
I just found this: https://github.com/jan-klos/dmn_pythonbut this library is not up to date I think... And is not compatible with camunda's xml files.

Thanks

Linking my class to a <task> xml node

Hi,

Can someone please provide an example of how to link a Simple task derivative to the node?. All s are by default treated as "Simple" type. What if I want to get my own derivative of Simple instead as the task spec? The NuclearStrike example is very clear for JSON, is there a similar one for the XML? I searched all over the internet, can't find a clear example for XML.

For the JSON example, I can see where this binding happens using the 'class' attribute - in dict.py
task_spec_cls = get_class(task_spec_state['class'])
task_spec = task_spec_cls.deserialize(self, spec, task_spec_state)

Is there a similar thing for XML. I tried providing a class attribute on the task node, but it obviously didn't work because there is no code in the XML Serializer consuming and acting on that.

What does exactly 'general' or 'president' do in tutorial/nuclear.json

Hello!

I got confused after I read the tutorial. The problem is that I can't find the function declaration of general or president in nuclear.json , therefore, I don't know what exactly general or president does. When workflow got Task president, it just completed, I couldn't find the execution of president and how did the attribute confirmation come out.

Actually, I want to implement several custom-tasks into a workflow so that it can make sure my tasks run well in programmed sequence like

{
    "task_specs": {
        "Start": {
            "class": "SpiffWorkflow.specs.StartTask.StartTask",
            "manual": false,
            "outputs": [
                "createEC2"
            ]
        },
        "custom-task1": {
            "class": "tasks.custom.CustomTask1",
            "name": "task1",
            "inputs": [
                "Start"
            ],
            "outputs": [
                "task2"
            ]
        },
       "custom-task2": {
            "class": "tasks.custom.CustomTask2",
            "name": "task2",
            "inputs": [
                "task1"
            ]
        },
        "workflow_aborted": {
            "class": "SpiffWorkflow.specs.Cancel.Cancel",
            "name": "workflow_aborted",
            "inputs": [
                "task1",
                "task2"
            ]
        }
    },
    "description": "",
    "file": null,
    "name": ""
}

So I have to understand how to write a custom task like NuclearStrike.

Add Sphinx-based documentation

The current documentation is incomplete. To complete it, a better documentation mechanism like Sphinx would be helpful.

Workflow global data

Hi,

I'm asking if it's possible to set a value at workflow level so I can set the value once (when it's available) and then use it in multiple tasks. Is it possible?

I read there is a get_data in workflow class but I'm not able to find how to set this data.

thanks

PatternTest.testPattern is failing

It is failing with the following callstack:

Traceback (most recent call last):
  File "/home/fcorreia/src/spiffworkflow/tests/SpiffWorkflow/PatternTest.py", line 80, in testPattern
    for filename in os.listdir(dirname):
OSError: [Errno 2] No such file or directory: '/home/fcorreia/src/spiffworkflow/tests/SpiffWorkflow/xml/spiff/resource/'

It happens because the test is looking for .xml files in a "resource" directory, that does not exist. I've fixed it on my end by ignoring that directory, but it might just have been forgotten on the previous commits.

Any real world usage example I can use to inspire myself?

Hi,

I've been taking a look at Spiffworkflow for a project I'm working on and it seems it could perfectly fit the bill, since I need to develop a workflow system where a process may have several steps, several people are involved in this process and have different permissions to execute certain steps, etc.

However I'm having trouble finding real usages of this library, and how to bind each task to python code or functions (e.g. notify by email a user once a step has been completed), how to decide which person is allowed to execute a certain step on a workflow, etc. Is there any complex implementation I could see as a source of inspiration?

Thank you and kind regards.
