msgpack is actually included as a requirement of oslo.privsep, with the following requirement:
msgpack>=0.5.0 # Apache-2.0 >From the changelog at https://github.com/msgpack/msgpack- python/blob/master/ChangeLog.rst it looks like max_bin_len was removed in 0.6.1, so perhaps there needs to be a limit set the version. Will re-assign to oslo.privsep for further investigation. ** Project changed: neutron => oslo.privsep -- You received this bug notification because you are a member of Yahoo!
