[Paraview-developers] Possible pvbatch bug?

[Paul Melis]

Hi,

I'm wondering if the behaviour below is a bug. I have a pvbatch test
script that runs fine under PV 3.10.1 and is actually based on an older
PV tutorial:

paulmlocal at sara11006:~/examples/paraview$ cat pvbatch_sphere.py
# spherepic.py
from paraview.simple import *

sm = servermanager
sm.Connect()

sphere = Sphere()
sphere.ThetaResolution = 100
sphere.PhiResolution = 100

pidscal = ProcessIdScalars(sphere)

view = sm.CreateRenderView()
rep = Show(pidscal, view)

nbprocs = sm.ActiveConnection.GetNumberOfDataPartitions()
lt = MakeBlueToRedLT(0, nbprocs-1)
lt.NumberOfTableValues = nbprocs

rep.LookupTable = lt
rep.ColorAttributeType = 'POINT_DATA'
rep.ColorArrayName = "ProcessId"

bar = CreateScalarBar(LookupTable=lt, Title='PID')

view.Representations.append(bar)
view.ResetCamera()
view.StillRender()
view.WriteImage("Sphere.0.png","vtkPNGWriter", 0)


When running this with the binary distro of 3.12.0 on a Linux x86_64
system I get:

paulmlocal at sara11006:~/examples/paraview$
~/software/ParaView-3.12.0-Linux-x86_64/bin/pvbatch pvbatch_sphere.py
ERROR: In
/home/kitware/Dashboards/MyTests/ParaView-master/ParaViewCore/ServerImplementation/vtkPVSessionCore.cxx,

vtkPVSessionCore (0x1a7f560): Attempt to assign existing ID 1.
while processing
Message 0 = Assign
  Argument 0 = id_value {1}
  Argument 1 = vtk_object_pointer {vtkPVSessionCoreInterpreterHelper
(0x2f6b310)}


ERROR: In

line 325
vtkPVSessionCore (0x1a7f560): Aborting execution for debugging purposes.

Aborted (core dumped)



Looking at the stack trace this seems to be something in the
underwater message handling? Should I file a bug report?

Regards,
Paul
