*should* be present.  For root scoped resources, namespace should
be ignored.  For namespaced resources, it is an error to have
Namespace=="".

Yu-Ju Hong 4a72addaeb Factor out API defaulting from validation logic 
Currently, the validation logic validates fields in an object and supply default
values wherever applies. This change factors out defaulting to a set of
defaulting callback functions for decoding (see #1502 for more discussion).

 * This change is based on pull request 2587.

 * Most defaulting has been migrated to defaults.go where the defaulting
   functions are added.

 * validation_test.go and converter_test.go have been adapted to not testing the
   default values.

 * Fixed all tests with that create invalid objects with the absence of
   defaulting logic.

Eric Tune ed74197fde Move Listers to pkg/client/cache. 
I would like to use these in kubelet and kube-proxy.
This is the minimal change to get them moved.
I will follow up with changes to make interfaces consistent
and add Listers for other resources.

Clayton Coleman b03fbf90f8 Make RESTClient more generic to API version, simplify version handling 
RESTClient is an abstraction on top of arbitrary HTTP endpoints that
follow the Kubernetes API conventions. Refactored RESTClientFor so that
assumptions that are Kube specific happen outside of that method (so
others can reuse the RESTClient). Added more validation to client.New
to ensure clients give good input. Exposed APIVersion on RESTClient
as a method so that wrapper code (code that adds typed / structured
methods over rest endpoints like client.Client) can more easily make
decisions about what APIVersion it is running under.

Eric Tune 7d5ac856c5 Make Reflector helpers reusable. 
Scheduler uses Reflector from pkg/client/cache.
It defines some helper classes.
I'd like to use those helpers with pkg/client/cache
in kube-proxy and kubelet too.

Clayton Coleman 82bcdd3b3b Make ResourceVersion a string internally instead of uint64 
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.

Clayton Coleman 4e56dafecc Introduce some default log verbosity control 
Move a lot of common error logging into better buckets:

glog.Errorf() - Always an error
glog.Warningf() - Something unexpected, but probably not an error
glog.V(0) - Generally useful for this to ALWAYS be visible
            to an operator
            * Programmer errors
            * Logging extra info about a panic
            * CLI argument handling
glog.V(1) - A reasonable default log level if you don't want
            verbosity
            * Information about config (listening on X, watching Y)
            * Errors that repeat frequently that relate to conditions
              that can be corrected (pod detected as unhealthy)
glog.V(2) - Useful steady state information about the service
            * Logging HTTP requests and their exit code
            * System state changing (killing pod)
            * Controller state change events (starting pods)
            * Scheduler log messages
glog.V(3) - Extended information about changes
            * More info about system state changes
glog.V(4) - Debug level verbosity (for now)
            * Logging in particularly thorny parts of code where
              you may want to come back later and check it
 2014-09-25 16:30:14 -04:00
Clayton Coleman 5483333e29 Allow server and client to take api version as argument 
* 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

Daniel Smith 3f659f7d74 Plumb pkg/client/cache changes into scheduler 2014-09-16 16:17:16 -07:00
Clayton Coleman 61e3ce7ddc Make runtime less global for Codec 
* 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

Daniel Smith dd862a7c53 Fix flaky scheduler factory test. 2014-08-28 20:32:20 -07:00
Clayton Coleman 818f357128 Client should validate the incoming host value 
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).
