Chris S. Kim 96c266becf Ensure connections are closed before WaitGroup marked as done
The previous ordering of defers meant the listener's connWG could fire and wake up other goroutines before the connection closed. Unsure if this caused any real bugs but this commit should make the code more correct.

Chris S. Kim 85dd506ecb Remove unnecessary goroutine in flaky test
The watch is established in a background goroutine and the first assertion proves that the watcher is active so there is no reason for the update to happen in a racy goroutine.

Note that this does not completely remove the race condition as the first call to testGetConfigValTimeout could time out before a config is returned.

Fix race during proxy closing (#13283)
p.service is written to within the Serve method. The Serve method also waits for the stopChan to be closed.

The race was between Close being called on the proxy causing Close on the service which was written to around the same time in the Serve method.

The fix is to have Serve be responsible for closing p.service.

Retry on bad dogstatsd connection (#13091)
- Introduce a new telemetry configurable parameter retry_failed_connection. User can set the value to true to let consul agent continue its start process on failed connection to datadog server. When set to false, agent will stop on failed start. The default behavior is true.

Daniel Nephin 4f0d092c95 testing: remove unnecessary calls to freeport
Previously we believe it was necessary for all code that required ports
to use freeport to prevent conflicts.

https://github.com/dnephin/freeport-test shows that it is actually save
to use port 0 (`127.0.0.1:0`) as long as it is passed directly to
`net.Listen`, and the listener holds the port for as long as it is
needed.

This works because freeport explicitly avoids the ephemeral port range,
and port 0 always uses that range. As you can see from the test output
of https://github.com/dnephin/freeport-test, the two systems never use
overlapping ports.

This commit converts all uses of freeport that were being passed
directly to a net.Listen to use port 0 instead. This allows us to remove
a bit of wrapping we had around httptest, in a couple places.

Daniel Nephin 03aa6106ff connect/proxy: fix a number of problems with Listener
We noticed that TestUpstreamListener would deadlock sometimes when run
with the race detector. While debugging this issue I found and fixed the
following problems.

1. the net.Listener was not being closed properly when Listener.Stop was
   called. This caused the Listener.Serve goroutine to run forever.
   Fixed by storing a reference to net.Listener and closing it properly
   when Listener.Stop is called.
2. call connWG.Add in the correct place. WaitGroup.Add must be called
   before starting a goroutine, not from inside the goroutine.
3. Set metrics config EnableRuntimeMetrics to `false` so that we don't
   start a background goroutine in each test for no reason. There is no
   way to shutdown this goroutine, and it was an added distraction while
   debugging these timeouts.
5. two tests were calling require.NoError from a goroutine.
   require.NoError calls t.FailNow, which MUST be called from the main
   test goroutine. Instead use t.Errorf, which can be called from other
   goroutines and will still fail the test.
6. `assertCurrentGaugeValue` wass breaking out of a for loop, which
   would cause the `RWMutex.RUnlock` to be missed. Fixed by calling
   unlock before `break`.

The core issue of a deadlock  was fixed by https://github.com/armon/go-metrics/pull/124.

Daniel Nephin ef0999547a testing: skip slow tests with -short
Add a skip condition to all tests slower than 100ms.

This change was made using `gotestsum tool slowest` with data from the
last 3 CI runs of master.

Daniel Nephin a7fec642fc ci: go-test-race switch to exclude list
Most packages should pass the race detector. An exclude list ensures
that new packages are automatically tested with -race.

Also fix a couple small test races to allow more packages to be tested.

Returning readyCh requires a lock because it can be set to nil, and
setting it to nil will race without the lock.

Move the TestServer.Listening calls around so that they properly guard
setting TestServer.l. Otherwise it races.

Remove t.Parallel in a small package. The entire package tests run in a
few seconds, so t.Parallel does very little.

In auto-config, wait for the AutoConfig.run goroutine to stop before
calling readPersistedAutoConfig. Without this change there was a data
race on reading ac.config.

R.B. Boyer 5c5f21088c sdk: add freelist tracking and ephemeral port range skipping to freeport
This should cut down on test flakiness.

Problems handled:

- If you had enough parallel test cases running, the former circular
approach to handling the port block could hand out the same port to
multiple cases before they each had a chance to bind them, leading to
one of the two tests to fail.

- The freeport library would allocate out of the ephemeral port range.
This has been corrected for Linux (which should cover CI).

- The library now waits until a formerly-in-use port is verified to be
free before putting it back into circulation.

Move the watch package into the api module (#5664)
* Move the watch package into the api module

It was already just a thin wrapper around the API anyways. The biggest change was to the testing. Instead of using a test agent directly from the agent package it now uses the binary on the PATH just like the other API tests.

The other big changes were to fix up the connect based watch tests so that we didn’t need to pull in the connect package (and therefore all of Consul)

Paul Banks 979e1c9c94 Add -sidecar-for and new /agent/service/:service_id endpoint (#4691)
- A new endpoint `/v1/agent/service/:service_id` which is a generic way to look up the service for a single instance. The primary value here is that it:
   - **supports hash-based blocking** and so;
   - **replaces `/agent/connect/proxy/:proxy_id`** as the mechanism the built-in proxy uses to read its config.
   - It's not proxy specific and so works for any service.
   - It has a temporary shim to call through to the existing endpoint to preserve current managed proxy config defaulting behaviour until that is removed entirely (tested).
 - The built-in proxy now uses the new endpoint exclusively for it's config
 - The built-in proxy now has a `-sidecar-for` flag that allows the service ID of the _target_ service to be specified, on the condition that there is exactly one "sidecar" proxy (that is one that has `Proxy.DestinationServiceID` set) for the service registered.
 - Several fixes for edge cases for SidecarService
 - A fix for `Alias` checks - when running locally they didn't update their state until some external thing updated the target. If the target service has no checks registered as below, then the alias never made it past critical.

Paul Banks 92fe8c8e89 Add Proxy Upstreams to Service Definition (#4639)
* Refactor Service Definition ProxyDestination.

This includes:
 - Refactoring all internal structs used
 - Updated tests for both deprecated and new input for:
   - Agent Services endpoint response
   - Agent Service endpoint response
   - Agent Register endpoint
     - Unmanaged deprecated field
     - Unmanaged new fields
     - Managed deprecated upstreams
     - Managed new
   - Catalog Register
     - Unmanaged deprecated field
     - Unmanaged new fields
     - Managed deprecated upstreams
     - Managed new
   - Catalog Services endpoint response
   - Catalog Node endpoint response
   - Catalog Service endpoint response
 - Updated API tests for all of the above too (both deprecated and new forms of register)

TODO:
 - config package changes for on-disk service definitions
 - proxy config endpoint
 - built-in proxy support for new fields

* Agent proxy config endpoint updated with upstreams

* Config file changes for upstreams.

* Add upstream opaque config and update all tests to ensure it works everywhere.

* Built in proxy working with new Upstreams config

* Command fixes and deprecations

* Fix key translation, upstream type defaults and a spate of other subtele bugs found with ned to end test scripts...

TODO: tests still failing on one case that needs a fix. I think it's key translation for upstreams nested in Managed proxy struct.

* Fix translated keys in API registration.
≈

* Fixes from docs
 - omit some empty undocumented fields in API
 - Bring back ServiceProxyDestination in Catalog responses to not break backwards compat - this was removed assuming it was only used internally.

* Documentation updates for Upstreams in service definition

* Fixes for tests broken by many refactors.

* Enable travis on f-connect branch in this branch too.

* Add consistent Deprecation comments to ProxyDestination uses

* Update version number on deprecation notices, and correct upstream datacenter field with explanation in docs
