Break Codec into two general purpose interfaces, Encoder and Decoder,
and move parameter codec responsibilities to ParameterCodec.
Make unversioned types explicit when registering - these types go
through conversion without modification.
Switch to use "__internal" instead of "" to represent the internal
version. Future commits will also add group defaulting (so that "" is
expanded internally into a known group version, and only cleared during
set).
For embedded types like runtime.Object -> runtime.RawExtension, put the
responsibility on the caller of Decode/Encode to handle transformation
into destination serialization. Future commits will expand RawExtension
and Unknown to accept a content encoding as well as bytes.
Make Unknown a bit more powerful and use it to carry unrecognized types.
A lot of packages use StringSet, but they don't use anything else from
the util package. Moving StringSet into another package will shrink
their dependency trees significantly.
OpenShift uses multiple API packages (types are split) which
Kube will also eventually have as we introduce more plugins.
These changes make the generators able to handle importing different
API object packages into a single generator function.
pkg/service:
There were a couple of references here just as a reminder to change the
behavior of findPort. As of v1beta3, TargetPort was always defaulted, so
we could remove findDefaultPort and related tests.
pkg/apiserver:
The tests were using versioned API codecs for some of their encoding
tests. Necessary API types had to be written and registered with the
fake versioned codecs.
pkg/kubectl:
Some tests were converted to current versions where it made sense.
