Self assignement in new Python Algorithms

Description (last modified by Martyn Gigg) (diff)

Trying to do something like this: 

a = CreateMDHistoWorkspace(SignalInput='1,2,3,4,5',ErrorInput='1,1,1,1,1',Dimensionality='1',Extents='-1,1',NumberOfBins='5',Names='A',Units='U')
b = CreateMDHistoWorkspace(SignalInput='1,2,3,4,5',ErrorInput='1,1,1,1,1',Dimensionality='1',Extents='-1,1',NumberOfBins='5',Names='A',Units='U')

c = a * b

a *= b

works in the mantid plot script window, but does not work with a combination of the new style python Algorithms and the unit test suite. Try running the code above using Stitch1D.py and run it from Stitch1DTest.py. The self assignment version hangs.

This seems to work for me now. Some changes in the underlying locking must have fixed it.
