This PR updates the tags that we generate for Envoy stats.
Several of these come with breaking changes, since we can't keep two stats prefixes for a filter.
* ci: stop building darwin/386 binaries
Go 1.15 drops support for 32-bit binaries on Darwin https://golang.org/doc/go1.15#darwin
* tls: ConnectionState::NegotiatedProtocolIsMutual is deprecated in Go 1.15, this value is always true
* correct error messages that changed slightly
* Completely regenerate some TLS test data

The Intention.Apply RPC is quite large, so this PR attempts to break it down into smaller functions and dissolves the pre-config-entry approach to the breakdown as it only confused things.
Header is: X-Consul-Default-ACL-Policy=<allow|deny>
This is of particular utility when fetching matching intentions, as the
fallthrough for a request that doesn't match any intentions is to
enforce using the default acl policy.
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.
defaultMetrics was being set at package import time, which meant that it received an instance of
the original default. But lib/telemetry.InitTelemetry sets a new global when it is called.
This resulted in the metrics being sent nowhere.
This commit changes defaultMetrics to be a function, so it will return the global instance when
called. Since it is called after InitTelemetry it will return the correct metrics instance.
The Catalog, Config Entry, KV and Session resources potentially re-validate the input as its coming in. We need to prevent snapshot restoration failures due to missing namespaces or namespaces that are being deleted in enterprise.
This ensures the metrics proxy endpoint is ACL protected behind a
wildcard `service:read` and `node:read` set of rules. For Consul
Enterprise these will need to span all namespaces:
```
service_prefix "" { policy = "read" }
node_prefix "" { policy = "read" }
namespace_prefix "" {
service_prefix "" { policy = "read" }
node_prefix "" { policy = "read" }
}
```
This PR contains just the backend changes. The frontend changes to
actually pass the consul token header to the proxy through the JS plugin
will come in another PR.
Added a new option `ui_config.metrics_proxy.path_allowlist`. This defaults to `["/api/v1/query", "/api/v1/query_range"]` when the metrics provider is set to `prometheus`.
Requests that do not use one of the allow-listed paths (via exact match) get a 403 Forbidden response instead.
1. do a state store query to list intentions as the agent would do over in `agent/proxycfg` backing `agent/xds`
2. upgrade the database and do a fresh `service-intentions` config entry write
3. the blocking query inside of the agent cache in (1) doesn't notice (2)
Makes Payload a type with FilterByKey so that Payloads can implement
filtering by key. With this approach we don't need to expose a Namespace
field on Event, and we don't need to invest micro formats or require a
bunch of code to be aware of exactly how the key field is encoded.
The output of the previous assertions made it impossible to debug the tests without code changes.
With go-cmp comparing the entire slice we can see the full diffs making it easier to debug failures.
Gauge metrics are great for understanding the current state, but can somtimes hide problems
if there are many disconnect/reconnects.
This commit adds counter metrics for connections and streams to make it easier to see the
count of newly created connections and streams.
Instead of using retry.Run, which appears to have problems in some cases where it does not
emit an error message, use a for loop.
Increase the number of attempts and remove any sleep, since this operation is not that expensive to do
in a tight loop
Closing l.conns can lead to a race and a 'panic: send on closed chan' when a
connection is in the middle of being handled when the server is shutting down.
Found using '-race -count=800'
