Previously the logic for reading ConfigFiles and produces Sources was split
between NewBuilder and Build. This commit moves all of the logic into NewBuilder
so that Build() can operate entirely on Sources.
This change is in preparation for logging warnings when files have an
unsupported extension.
It also reduces the scope of BuilderOpts, and gets us very close to removing
Builder.options.
The nil value was never used. We can avoid a bunch of complications by
making the field a string value instead of a pointer.
This change is in preparation for fixing a silent config failure.
Flags is an overloaded term in this context. It generally is used to
refer to command line flags. This struct, however, is a data object
used as input to the construction.
It happens to be partially populated by command line flags, but
otherwise has very little to do with them.
Renaming this struct should make the actual responsibility of this struct
more obvious, and remove the possibility that it is confused with
command line flags.
This change is in preparation for adding additional fields to
BuilderOpts.
This field was populated for one reason, to test that it was empty.
Of all the callers, only a single one used this functionality. The rest
constructed a `Flags{}` struct which did not set Args.
I think this shows that the logic was in the wrong place. Only the agent
command needs to care about validating the args.
This commit removes the field, and moves the logic to the one caller
that cares.
Also fix some comments.
Blocking queries issues will still be uncancellable (that cannot be helped until we get rid of net/rpc). However this makes it so that if calling getWithIndex (like during a cache Notify go routine) we can cancell the outer routine. Previously it would keep issuing more blocking queries until the result state actually changed.
Also handle []interface{} in HookWeakDecodeFromSlice
Without this change only the top level []map[string]interface{} will be
unpacked as a single item. With this change any nested config will be
unpacked.

Currently when passing hostname clusters to Envoy, we set each service instance registered with Consul as an LbEndpoint for the cluster.
However, Envoy can only handle one per cluster:
[2020-06-04 18:32:34.094][1][warning][config] [source/common/config/grpc_subscription_impl.cc:87] gRPC config for type.googleapis.com/envoy.api.v2.Cluster rejected: Error adding/updating cluster(s) dc2.internal.ddd90499-9b47-91c5-4616-c0cbf0fc358a.consul: LOGICAL_DNS clusters must have a single locality_lb_endpoint and a single lb_endpoint, server.dc2.consul: LOGICAL_DNS clusters must have a single locality_lb_endpoint and a single lb_endpoint
Envoy is currently handling this gracefully by only picking one of the endpoints. However, we should avoid passing multiple to avoid these warning logs.
This PR:
* Ensures we only pass one endpoint, which is tied to one service instance.
* We prefer sending an endpoint which is marked as Healthy by Consul.
* If no endpoints are healthy we emit a warning and skip the cluster.
* If multiple unique hostnames are spread across service instances we emit a warning and let the user know which will be resolved.
* Add Health Checks and update Tooltips in Ingress Upstreams
* Update Tooltip in Proxy Info tab Upstreams
* Add Tooltips to Proxy Info tab Exposed Paths
* Add Health Checks with Tooltips to Service List page
This excludes any /components/**/pageobject.js files from our production
builds which means we can co-locate all of our component page objects
(and selectors) along with the components themselves.
In discussion with team, it was pointed out that query parameters tend
to be filter mechanism, and that semantically the "/v1/health/connect"
endpoint should return "all healthy connect-enabled endpoints (e.g.
could be side car proxies or native instances) for this service so I can
connect with mTLS".
That does not fit an ingress gateway, so we remove the query parameter
and add a new endpoint "/v1/health/ingress" that semantically means
"all the healthy ingress gateway instances that I can connect to
to access this connect-enabled service without mTLS"
* ui: Reduce discovery-chain log spam
Currently the only way that the UI can know whether connect is enabled
or not is whether we get 500 errors from certain endpoints.
One of these endpoints we already use, so aswell as recovering from a
500 error, we also remember that connect is disabled for the rest of the
page 'session' (so until the page is refreshed), and make no further
http requests to the endpoint for that specific datacenter.
This means that log spam is reduced to only 1 log per page refresh/dc
instead of 1 log per service navigation.
Longer term we'll need some way to dynamically discover whether connect
is enabled per datacenter without relying on something that will add
error logs to consul.
