Stefania edited comment on CASSANDRA-11574 at 4/22/16 12:06 AM: ---------------------------------------------------------------- You're welcome, thanks for helping us debug this. -.pyc- .c and .so are actually Cython extensions and they must be deleted manually or else changing the .py has not effect. I had no idea they would be present in package deployments. CASSANDRA-11053, which was delivered in 3.0.5, modified _pylib/setup.py_ so that people can create these files manually for added performance by typing {{python setup.py build_ext --inplace}} in the pylib folder. They must be generated somewhere when the package is created. [~mshuler]: do you know how the packaging process uses _pylib/setup.py_? The initial solution, {{copy_options\['numprocesses'\] = int(opts.pop('numprocesses', self.get_num_processes(16)))}} is actually correct, provided the -.pyc- .c and .so are regenerated by running {{python setup.py build_ext --inplace}} or, as you already pointed out, if they are removed (in which case the original code also works). I will prepare a patch so that the Cython extensions also work. was (Author: stefania): You're welcome, thanks for helping us debug this. .pyc and .so are actually Cython extensions and they must be deleted manually or else changing the .py has not effect.
