Alpha tester wanted: Collaborative FC add-on

[wmayer]

get_default_loop is not used in my code. Was there any more information, a stack-trace maybe? I wonder where this is coming from

Sorry, here is it:

Code: Select all

Traceback (most recent call last):
  File "/home/user/.FreeCAD/Mod/CollaborativeFC/Utils/AsyncSlot.py", line 35, in _runner
    await fnc(*args, **kwargs)
  File "/home/user/.FreeCAD/Mod/CollaborativeFC/OCP/API.py", line 234, in toggleConnectedSlot
    await self.connectToNode()
  File "/home/user/.FreeCAD/Mod/CollaborativeFC/OCP/API.py", line 80, in connectToNode
    self.__wamp.start()
  File "/usr/lib/python3/dist-packages/autobahn/asyncio/component.py", line 309, in start
    loop = asyncio.get_default_loop()
AttributeError: module 'asyncio' has no attribute 'get_default_loop'

EDIT:
What fixed it is to get an up-to-date autobahn package with pip3 download autobahn
Afterwards it allows me to connect to the p2p network.

Ok, I pushed updates that should adress most, if not all of the reported problems. I cannot test the python2/3 version issue on my machine, but this is how I tried to solve it:

Code: Select all

pyCmd = "python"
            if platform.system() == "Linux":
                fcPy = sys.version_info[0]
                process = await asyncio.create_subprocess_shell("python --version", stdout=asyncio.subprocess.PIPE, stderr=asyncio.subprocess.PIPE)
                out, err = await process.communicate()
        
                if not out:
                    raise Exception("Unable to detect the default python version")               
                if err and err.decode() != "":
                    raise Exception("Unable to detect the default python version: ", err.decode())
                
                sysPy = out.decode()[-5]
                if sysPy != fcPy:
                    pyCmd += str(fcPy)

Hopefully that works.

@ickby not sure you know this or not but if you want to test for different version of FC or even different branches (i.e. LinkStage3) take a look at:

https://github.com/FreeCAD/FreeCAD-macr ... 1b4d72c279

Code: Select all

if App.Version()[1].find('18') == 0: import DraftTrackers, Draft
if App.Version()[1].find('19') == 0: import draftguitools.gui_trackers as DraftTrackers
if App.Version()[5].find('LinkStage3') == 0: import draftguitools.gui_trackers as DraftTrackers

Then your addon can recognize that the 2 peers involved are both FC master or LinkStage3 etc...

I detailed the actions testers can help me with in the first topic. For completeness here is what I hope someone is willing to go through:

Can you find FreeCAD workflows, actions, etc. that lead to unsynchronized documents in the multiple open FreeCAD instances? Do the following:
3.1. Setup two FreeCad instances and and make sure both are connected to the network
3.2 Open a document on the first instance and share it.
3.3 In the second instance it will show up as "node" type document, open it there
4.4 In any instance, try a FreeCAD workflow, e.g. PartDesign, Draft, Arch, FEM, Path... whatever you can think of
4.5 On each step check, if the second instance does replicate your action correctly and the documents are the same
4.6 If the documents are not the same, or an error occurred in the report view, try to make a minimal example out of it that fails reproducible
4.7 Get creative in breaking it (except the known issues )

I'm really looking for the examples that fail, to add it to my unit tests and improve the overall code.
