receiver name obj should be consistent with previous receiver name s for SimpleStream
error var hookNotFinished should have name of the form errFoo

- as soon as a request is received by the apiserver, determine the
timeout of the request and set a new request context with the deadline.
- the timeout filter that times out non-long-running requests should
use the request context as opposed to a fixed 60s wait today.
- admission and storage layer uses the same request context with the
deadline specified.
we use the default timeout enforced by the apiserver:
- if the user has specified a timeout of 0s, this implies no timeout on the user's part.
- if the user has specified a timeout that exceeds the maximum deadline allowed by the apiserver.

The previous HTTP compression implementation functioned as a filter, which
required it to deal with a number of special cases that complicated the
implementation.
Instead, when we write an API object to a response, handle only that one
case. This will allow a more limited implementation that does not impact
other code flows.
Also, to prevent excessive CPU use on small objects, compression is
disabled on responses smaller than 128Kb in size.

conflict.
Adding unit test verify that deleteValidation is retried.
adding e2e test verifying the webhook can intercept configmap and custom
resource deletion, and the existing object is sent via the
admissionreview.OldObject.
update the admission integration test to verify that the existing object
is passed to the deletion admission webhook as oldObject, in case of an
immediate deletion and in case of an update-on-delete.

Typo during setting up PartialObjectMetadataList, it should be a slice
of `PartialObjectMetadata`, not a slice of `*PartialObjectMetadata`.

Now that internal types are equivalent, allow the apiserver to serve
metav1 and metav1beta1 depending on the client. Test that in the
apiserver integration test and ensure we get the appropriate responses.
Register the metav1 type in the appropriate external locations.

Clean up the code paths that lead to objects being transformed and output with negotiation.
Remove some duplicate code that was not consistent. Now, watch will respond correctly to
Table and PartialObjectMetadata requests. Add unit and integration tests.
When transforming responses to Tables, only the first watch event for a given type will
include the columns. Columns will not change unless the watch is restarted.
Add a volume attachment printer and tighten up table validation error cases.
Disable protobuf from table conversion because Tables don't have protobuf because they
use `interface{}`

- Added metav1.Status() that enforces '406 Not Acceptable' response if
protobuf serialization is not fully supported for the API resource type.
- JSON and YAML serialization are supposed to be more completely baked
in, so serialization involving those, and general errors with seralizing
protobuf, will return '500 Internal Server Error'.
- If serialization failure occurs and original HTTP status code is
error, use the original status code, else use the serialization failure
status code.
- Write encoded API responses to intermediate buffer
- Use apimachinery/runtime::Encode() instead of
apimachinery/runtime/protocol::Encode() in
apiserver/endpoints/handlers/responsewriters/writers::SerializeObject()
- This allows for intended encoder error handling to fully work, facilitated by
apiserver/endpoints/handlers/responsewriters/status::ErrorToAPIResponse() before officially
writing to the http.ResponseWriter
- The specific part that wasn't working by ErrorToAPIResponse() was the
HTTP status code set. A direct call to
http.ResponseWriter::WriteHeader(statusCode) was made in
SerializeObject() with the original response status code, before
performing the encode. Once this
method is called, it can not again update the status code at a later
time, with say, an erro status code due to encode failure.
- Updated relevant apiserver unit test to reflect the new behavior
(TestWriteJSONDecodeError())
- Add build deps from make update for protobuf serializer
50342: Code review suggestion impl
- Ensure that http.ResponseWriter::Header().Set() is called before http.ResponseWriter::WriteHeader()
- This will avert a potential issue where changing the response media type to text/plain wouldn't work.
- We want to respond with plain text if serialization fails of the original response, and serialization also fails for the resultant error response.
50342: wrapper for http.ResponseWriter
- Prevent potential performance regression caused by modifying encode to use a buffer instead of streaming
- This is achieved by creating a wrapper type for http.ResponseWriter that will use WriteHeader(statusCode) on the first
call to Write(). Thus, on encode success, Write() will write the original statusCode. On encode failure, we pass control
onto responsewriters::errSerializationFatal(), which will process the error to obtain potentially a new status code, depending
on whether or not the original status code was itself an error.
50342: code review suggestions
- Remove historical note from unit test comment
- Don't export httpResponseWriterWithInit type (for now)
