Allows us to define different watch versioning regimes in the future
as well as to encode information with the resource version.
This changes /watch/resources?resourceVersion=3 to start the watch at
4 instead of 3, which means clients can read a resource version and
then send it back to the server. Clients should no longer do math on
resource versions.
* Allows consumers to provide their own transports for common cases.
* Supports KUBE_API_VERSION on test cases for controlling which
api version they test against
* Provides a common flag registration method for CLIs that need
to connect to an API server (to avoid duplicating flags)
* Ensures errors are properly returned by the server
* Add a Context field to client.Config
* Defaults to v1beta1
* apiserver takes -storage_version which controls etcd storage version
and the version of the client used to connect to other apiservers
* Changed signature of client.New to add version parameter
* All controller code and component code prefers the oldest (most common)
server version
* Make Codec separate from Scheme
* Move EncodeOrDie off Scheme to take a Codec
* Make Copy work without a Codec
* Create a "latest" package that imports all versions and
sets global defaults for "most recent encoding"
* v1beta1 is the current "latest", v1beta2 exists
* Kill DefaultCodec, replace it with "latest.Codec"
* This updates the client and etcd to store the latest known version
* EmbeddedObject is per schema and per package now
* Move runtime.DefaultScheme to api.Scheme
* Split out WatchEvent since it's not an API object today, treat it
like a special object in api
* Kill DefaultResourceVersioner, instead place it on "latest" (as the
package that understands all packages)
* Move objDiff to runtime.ObjectDiff
This is some cleanup that has been needed for a while.
There's still one more step that could usefully be done, which is to
split up our api package into the part that provides the helper
functions and the part that provides the internal types. That can come
later.
The v1beta1 package is now a good example of what an api plugin should
do to version its types.
Convert host:port and URLs passed to client.New() into the proper
values, and return an error if the value is invalid. Change CLI
to return an error if -master is invalid. Remove Client.rawRequest
which was not in use, and fix the involved tests. Add NewOrDie
Preserves the behavior of the client to not auth when a non-https
URL is passed (although in the future this should be corrected).
Improve apiserver/logger.go's interface (it's pretty cool now).
Improve apiserver's error reporting to clients.
Improve client's handling of errors from apiserver.
Make failed PUTs return 409 (conflict)-- http status codes are amazingly
well defined for what we're doing!
