R.B. Boyer	20caa4f744	test: for envoy integration tests, wait until 's2' is healthy in consul before interrogating envoy (#6108) ... When the envoy healthy panic threshold was explicitly disabled as part of L7 traffic management it changed how envoy decided to load balance to endpoints in a cluster. This only matters when envoy is in "panic mode" aka "when you have a bunch of unhealthy endpoints". Panic mode sends traffic to unhealthy instances in certain circumstances. Note: Prior to explicitly disabling the healthy panic threshold, the default value is 50%. What was happening is that the test harness was bringing up consul the sidecars, and the service instances all at once and sometimes the proxies wouldn't have time to be checked by consul to be labeled as 'passing' in the catalog before a round of EDS happened. The xDS server in consul effectively queries /v1/health/connect/s2 and gets 1 result, but that one result has a 'critical' check so the xDS server sends back that endpoint labeled as UNHEALTHY. Envoy sees that 100% of the endpoints in the cluster are unhealthy and would enter panic mode and still send traffic to s2. This is why the test suites PRIOR to disabling the healthy panic threshold worked. They were _incorrectly_ passing. When the healthy panic threshol is disabled, envoy never enters panic mode in this situation and thus the cluster has zero healthy endpoints so load balancing goes nowhere and the tests fail. Why does this only affect the test suites for envoy 1.8.0? My guess is that https://github.com/envoyproxy/envoy/pull/4442 was merged into the 1.9.x series and somehow that plays a role. This PR modifies the bats scripts to explicitly wait until the upstream sidecar is healthy as measured by /v1/health/connect/s2?passing BEFORE trying to interrogate envoy which should make the tests less racy.	5 years ago
Paul Banks	0cfb6051ea	Add integration test for central config; fix central config WIP (#5752) ... * Add integration test for central config; fix central config WIP * Add integration test for central config; fix central config WIP * Set proxy protocol correctly and begin adding upstream support * Add upstreams to service config cache key and start new notify watcher if they change. This doesn't update the tests to pass though. * Fix some merging logic get things working manually with a hack (TODO fix properly) * Simplification to not allow enabling sidecars centrally - it makes no sense without upstreams anyway * Test compile again and obvious ones pass. Lots of failures locally not debugged yet but may be flakes. Pushing up to see what CI does * Fix up service manageer and API test failures * Remove the enable command since it no longer makes much sense without being able to turn on sidecar proxies centrally * Remove version.go hack - will make integration test fail until release * Remove unused code from commands and upstream merge * Re-bump version to 1.5.0	6 years ago
