Only attempt to construct GC informers for watchable resources 2017-11-15 02:26:58 -05:00

Dan Mace c3dd82c30c Tolerate partial discovery in garbage collector 
Allow the garbage collector to tolerate partial discovery failures. On a
partial failure, use whatever was discovered, log the failures, and
allow the resync logic to try again later.

Fixes #55022.

Disable default paging in list watches 
For 1.8 this will be off by default. In 1.9 it will be on by default.
Add tests and rename some fields to use the `chunking` terminology.

Note that the pager may be used for other things besides chunking.

Server side implementation of paging for etcd3 
Add a feature gate in the apiserver to control whether paging can be
used. Add controls to the storage factory that allow it to be disabled
per resource. Use a JSON encoded continuation token that can be
versioned. Create a 410 error if the continuation token is expired.

Adds GetContinue() to ListMeta.

Dan Mace 3d6d57a18f Improve GC discovery sync performance 
Improve GC discovery sync performance by only syncing when discovered
resource diffs are detected. Before, the GC worker pool was shut down
and monitors resynced unconditionally every sync period, leading to
significant processing delays causing test flakes where otherwise
reasonable GC timeouts were being exceeded.

Related to https://github.com/kubernetes/kubernetes/issues/49966.

Dan Mace d08dfb92c7 Enable garbage collection of custom resources 
Enhance the garbage collector to periodically refresh the resources it
monitors (via discovery) to enable custom resource definition GC.

This implementation caches Unstructured structs for any kinds not
covered by a shared informer. The existing meta-only codec only supports
compiled types; an improved codec which supports arbitrary types could
be introduced to optimize caching to store only metadata for all
non-informer types.

Replace negotiation with a new method that can extract info 
Alter how runtime.SerializeInfo is represented to simplify negotiation
and reduce the need to allocate during negotiation. Simplify the dynamic
client's logic around negotiating type. Add more tests for media type
handling where necessary.

Allow garbage collection to work against different API prefixes 
The GC needs to build clients based only on Resource or Kind. Hoist the
restmapper out of the controller and the clientpool, support a new
ClientForGroupVersionKind and ClientForGroupVersionResource, and use the
appropriate one in both places.

Automatic merge from submit-queue

[GarbageCollector] measure latency

First commit is #27600.

In e2e tests, I measure the average time an item spend in the eventQueue(~1.5 ms), dirtyQueue(~13ms), and orphanQueue(~37ms). There is no stress test in e2e yet, so the number may not be useful.

Automatic merge from submit-queue

pkg/controller/garbagecollector: simplify mutexes.

pkg/controller/garbagecollector: simplified synchronization and made idiomatic.


Similar to #29598, we can rely on the zero-value construction behavior
to embed `sync.Mutex` into parent structs.
