Frederic Branczyk	7b1c0d6b66	discovery/kubernetes: Fix incorrect premature break of reading results ... Previously `max` results stopped reading from results in tests prematurely, as it stopped when `max` number of items were received from the channel instead of `max` number of unique target groups received. This caused flaky tests where the same target group was received multiple times, as Kubernetes informers may emit the same event multiple times. Before this patch, running this test repeatedly failed eventually. After this patch I have run the test many thousand times without failure. ```bash go test -run TestEndpointsDiscoveryNamespaces -count 1000 -test.v ``` Signed-off-by: Frederic Branczyk <fbranczyk@gmail.com>	6 years ago

Yecheng Fu	8ceb8f2ae8	Refactor Kubernetes Discovery Part 2: Refactoring ... - Do initial listing and syncing to scrape manager, then register event handlers may lost events happening in listing and syncing (if it lasted a long time). We should register event handlers at the very begining, before processing just wait until informers synced (sync in informer will list all objects and call OnUpdate event handler). - Use a queue then we don't block event callbacks and an object will be processed only once if added multiple times before it being processed. - Fix bug in `serviceUpdate` in endpoints.go, we should build endpoints when `exists && err == nil`. Add `^TestEndpointsDiscoveryWithService` tests to test this feature. Testing: - Use `k8s.io/client-go` testing framework and fake implementations which are more robust and reliable for testing. - `Test\w+DiscoveryBeforeRun` are used to test objects created before discoverer runs - `Test\w+DiscoveryAdd\w+` are used to test adding objects - `Test\w+DiscoveryDelete\w+` are used to test deleting objects - `Test\w+DiscoveryUpdate\w+` are used to test updating objects - `TestEndpointsDiscoveryWithService\w+` are used to test endpoints events triggered by services - `cache.DeletedFinalStateUnknown` related stuffs are removed, because we don't care deleted objects in store, we only need its name to send a specical `targetgroup.Group` to scrape manager Signed-off-by: Yecheng Fu <cofyc.jackson@gmail.com>	8 years ago
