Subject: classmethod-related changes for cls argument
To: Stefan Behnel <[email protected]>
Stefan, I'm very busy with personal stuff, so no time at all to look
on this. You have below the output from an interactive IPython
session. Perhaps you forgot to update some code counting function
arguments (I bet such code was discounting self_arg, but you should
also discount type_arg?)
In [1]: from mpi4py import MPI
In [2]: MPI.Comm.Compare?
Type: builtin_function_or_method
Base Class: <type 'builtin_function_or_method'>
String Form: <built-in method Compare of type object at 0x2b6b038e0e20>

Docstring:
Comm.Compare(type cls, Comm comm1, Comm comm2)
Compare two communicators
In [3]: MPI.Comm.Compare(MPI.COMM_WORLD, MPI.COMM_WORLD)

The patch below fixes my issues, but I not sure if this is the
definitive solution ...
