I'm working on providing support in mpi4py for complex types, and then
I did more or les this:
cdef class Datatype: # cdef class
MPI_Datatype ob_mpi
cdef Datatype COMPLEX = Datatype() # cdef global
cdef void setup_complex_types() nogil: # nogil function
cdef MPI_Datatype newtype
create_complex_type(&newtype) # implemented elsewhere
COMPLEX.ob_mpi = newtype # Look HERE !
As you see, I'm touching a C field of the object structure inside a
"nogil" function.
I'm very hapy it worked!! . AFAIK, there are no GIL issues in this
code. Anyway, I would like to know your opinion on this.
