Daniel Nephin	29e93f6338	grpc: fix a data race by using a static resolver 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.	4 years ago
Matt Keeler	da31e0449e	Move some things around to allow for license updating via config reload 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.	4 years ago

Daniel Nephin	79a54f208e	agent: fix data race in tests caused by grpc log init grpclog.SetLoggerV2 is meant to be called only once before any gRPC requests are received, but each test that uses TestAgent will call NewBaseDeps again. Use a sync.Once to prevent the grpc logging from being re-initialized by each test. This will mean that a test can't use a fake logger to capture logs from the gRPC server.	4 years ago

Daniel Nephin	97a577502d	config: improve the interface of Load This commit reduces the interface to Load() a bit, in preparation for unexporting NewBuilder and having everything call Load. The three arguments are reduced to a single argument by moving the other two into the options struct. The three return values are reduced to two by moving the RuntimeConfig and Warnings into a LoadResult struct.	4 years ago

Daniel Nephin	2294793357	agent/grpc: use router.Manager to handle the rebalance The router.Manager is already rebalancing servers for other connection pools, so it can call into our resolver to do the same. This change allows us to remove the serf dependency from resolverBuilder, and remove Datacenter from the config. Also revert the change to refreshServerRebalanceTimer	4 years ago
Daniel Nephin	bad4d3ff7c	grpc: redeuce dependencies, unexport, and add godoc Rename GRPCClient to ClientConnPool. This type appears to be more of a conn pool than a client. The clients receive the connections from this pool. Reduce some dependencies by adjusting the interface baoundaries. Remove the need to create a second slice of Servers, just to pick one and throw the rest away. Unexport serverResolver, it is not used outside the package. Use a RWMutex for ServerResolverBuilder, some locking is read-only. Add more godoc.	4 years ago
Daniel Nephin	cdd392d77f	agent/consul: pass dependencies directly from agent In an upcoming change we will need to pass a grpc.ClientConnPool from BaseDeps into Server. While looking at that change I noticed all of the existing consulOption fields are already on BaseDeps. Instead of duplicating the fields, we can create a struct used by agent/consul, and use that struct in BaseDeps. This allows us to pass along dependencies without translating them into different representations. I also looked at moving all of BaseDeps in agent/consul, however that created some circular imports. Resolving those cycles wouldn't be too bad (it was only an error in agent/consul being imported from cache-types), however this change seems a little better by starting to introduce some structure to BaseDeps. This change is also a small step in reducing the scope of Agent. Also remove some constants that were only used by tests, and move the relevant comment to where the live configuration is set. Removed some validation from NewServer and NewClient, as these are not really runtime errors. They would be code errors, which will cause a panic anyway, so no reason to handle them specially here.	4 years ago

Daniel Nephin	63bad36de7	testing: disable global metrics sink in tests This might be better handled by allowing configuration for the InMemSink interval and retail, and disabling the global. For now this is a smaller change to remove the goroutine leak caused by tests because go-metrics does not provide any way of shutting down the global goroutine.	4 years ago
Daniel Nephin	5d4df54296	agent: extract dependency creation from New With this change, Agent.New() accepts many of the dependencies instead of creating them in New. Accepting fully constructed dependencies from a constructor makes the type easier to test, and easier to change. There are still a number of dependencies created in Start() which can be addressed in a follow up.	4 years ago
