New submission from CireSnave <[email protected]>:
It appears that Python's socket module is missing support for the IGMPv3 socket
options needed to support Source Specific Multicast. Many developers appear to
be adding the necessary constants through something like:
if not hasattr(socket, "IP_UNBLOCK_SOURCE"):
setattr(socket, "IP_UNBLOCK_SOURCE", 37)
if not hasattr(socket, "IP_BLOCK_SOURCE"):
setattr(socket, "IP_BLOCK_SOURCE", 38)
if not hasattr(socket, "IP_ADD_SOURCE_MEMBERSHIP"):
setattr(socket, "IP_ADD_SOURCE_MEMBERSHIP", 39)
if not hasattr(socket, "IP_DROP_SOURCE_MEMBERSHIP"):
setattr(socket, "IP_DROP_SOURCE_MEMBERSHIP", 40)
...but it would be nice if these were added to the official module as they are
supported under current versions of Windows, Linux, and BSD at the least.
