When info.Timeout is 0, it should have no timeout. Previously it was using a 0 duration timeout
which caused it to return without waiting.
This bug was masked by using a timeout in the tests. Removing the timeout caused the tests to fail.
This PR adds cluster members to the metrics API. The number of members per
segment are reported as well as the total number of members.
Tested by running a multi-node cluster locally and ensuring the numbers were
correct. Also added unit test coverage to add the new expected gauges to
existing test cases.
We have seen test flakes caused by 'concurrent map read and map write', and the race detector
reports the problem as well (prevent us from running some tests with -race).
The root of the problem is the grpc expects resolvers to be registered at init time
before any requests are made, but we were using a separate resolver for each test.
This commit introduces a resolver registry. The registry is registered as the single
resolver for the consul scheme. Each test uses the Authority section of the target
(instead of the scheme) to identify the resolver that should be used for the test.
The scheme is used for lookup, which is why it can no longer be used as the unique
key.
This allows us to use a lock around the map of resolvers, preventing the data race.
* fix tests to use a dummy nodeName and not fail when hostname is not a valid nodeName
* remove conditional testing
* add test when node name is invalid
* debug: remove the CLI check for debug_enabled
The API allows collecting profiles even debug_enabled=false as long as
ACLs are enabled. Remove this check from the CLI so that users do not
need to set debug_enabled=true for no reason.
Also:
- fix the API client to return errors on non-200 status codes for debug
endpoints
- improve the failure messages when pprof data can not be collected

* remove parallel test runs
parallel runs create a race condition that fail the debug tests
* Add changelog

The bulk of this commit is moving the LeaderRoutineManager from the agent/consul package into its own package: lib/gort. It also got a renaming and its Start method now requires a context. Requiring that context required updating a whole bunch of other places in the code.
This refactor is to make it easier to see how serf feature flags are
encoded as serf tags, and where those feature flags are read.
- use constants for both the prefix and feature flag name. A constant
makes it much easier for an IDE to locate the read and write location.
- isolate the feature-flag encoding logic in the metadata package, so
that the feature flag prefix can be unexported. Only expose a function
for encoding the flags into tags. This logic is now next to the logic
which reads the tags.
- remove the duplicate `addEnterpriseSerfTags` functions. Both Client
and Server structs had the same implementation. And neither
implementation needed the method receiver.
The prior solution to call reply.Reset() aged poorly since newer fields
were added to the reply, but not added to Reset() leading serial
blocking query loops on the server to blend replies.
This could manifest as a service-defaults protocol change from
default=>http not reverting back to default after the config entry
reponsible was deleted.
* Save exposed HTTP or GRPC ports to the agent's store
* Add those the health checks API so we can retrieve them from the API
* Change redirect-traffic command to also exclude those ports from inbound traffic redirection when expose.checks is set to true.
TestACLEndpoint_Login_with_TokenLocality was reguardly being reported as failed even though
it was not failing. I took another look and I suspect it is because t.Parllel was being
called in a goroutine.
This would lead to strange behaviour which apparently confused the 'go test' runner.
- return errors in TestAgent.Start so that the retry works correctly
- remove duplicate logging, the error is returned already
- add a missing t.Helper() to retry.Run
- properly set a.Agent to nil so that subsequent retry attempts will actually try to start
