Daniel Nephin	970f5d78ec	agent: fix two data race in agent tests The LogOutput io.Writer used by TestAgent must allow concurrent reads and writes, and a bytes.Buffer does not allow this. The bytes.Buffer must be wrapped with a lock to make this safe.	3 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	32d36d0dd4	config: replace calls to config.NewBuilder with config.Load This is another incremental change to reduce config loading to a single small interface. All calls to NewBuilder can be replaced with Load.	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	282fbdfa75	api: rename HTTPServer to HTTPHandlers Resolves a TODO about naming. This type is a set of handlers for an http.Server, it is not itself a Server. It provides http.Handler functions.	4 years ago
Daniel Nephin	0bb9c318b7	http: fix tests incorrectly using HTTPAddr to get the address of the https server. In #8234 I changed a few tests to use TestAgent.HTTPAddr() to find the addr used in the test. Due to the way HTTPAddr() was implemented these tests were passing, but I think the pass was incidental. HTTPAddr() was not matching any servers, and was instead returning the last server, which happened to be the one these tests wanted. This commit fixes the implementation of HTTPAddr to panic if no match was found. The tests which require an HTTPS server are changed to use a new firstAddr() to look up the correct address.	4 years ago
Daniel Nephin	6ca45e1a61	agent: add apiServers type for managing HTTP servers Remove Server field from HTTPServer. The field is no longer used.	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
Daniel Nephin	070e843113	testutil: Add t.Cleanup to TempDir TempDir registers a Cleanup so that the directory is always removed. To disable to cleanup, set the TEST_NOCLEANUP env var.	4 years ago
Daniel Nephin	3a4e62836b	testing: Remove TestAgent.Key and change TestAgent.DataDir TestAgent.Key was only used by 3 tests. Extracting it from the common helper that is used in hundreds of tests helps keep the shared part small and more focused. This required a second change (which I was planning on making anyway), which was to change the behaviour of DataDir. Now in all cases the TestAgent will use the DataDir, and clean it up once the test is complete.	4 years ago

Daniel Nephin	51efba2c7d	testutil: NewLogBuffer - buffer logs until a test fails Replaces #7559 Running tests in parallel, with background goroutines, results in test output not being associated with the correct test. `go test` does not make any guarantees about output from goroutines being attributed to the correct test case. Attaching log output from background goroutines also cause data races. If the goroutine outlives the test, it will race with the test being marked done. Previously this was noticed as a panic when logging, but with the race detector enabled it is shown as a data race. The previous solution did not address the problem of correct test attribution because test output could still be hidden when it was associated with a test that did not fail. You would have to look at all of the log output to find the relevant lines. It also made debugging test failures more difficult because each log line was very long. This commit attempts a new approach. Instead of printing all the logs, only print when a test fails. This should work well when there are a small number of failures, but may not work well when there are many test failures at the same time. In those cases the failures are unlikely a result of a specific test, and the log output is likely less useful. All of the logs are printed from the test goroutine, so they should be associated with the correct test. Also removes some test helpers that were not used, or only had a single caller. Packages which expose many functions with similar names can be difficult to use correctly.

Daniel Nephin	a5e45defb1	agent/http: un-embed the HTTPServer The embedded HTTPServer struct is not used by the large HTTPServer struct. It is used by tests and the agent. This change is a small first step in the process of removing that field. The eventual goal is to reduce the scope of HTTPServer making it easier to test, and split into separate packages.	4 years ago
Matt Keeler	d6e05482ab	Allow cancelling startup when performing auto-config (#8157 ) Co-authored-by: Daniel Nephin <dnephin@hashicorp.com>	4 years ago
Matt Keeler	3dbbd2d37d	Implement Client Agent Auto Config There are a couple of things in here. First, just like auto encrypt, any Cluster.AutoConfig RPC will implicitly use the less secure RPC mechanism. This drastically modifies how the Consul Agent starts up and moves most of the responsibilities (other than signal handling) from the cli command and into the Agent.	4 years ago
Daniel Nephin	77101eee82	config: rename Flags to BuilderOpts 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.	4 years ago

Daniel Nephin	ad7c78f134	Remove t.Name() from TestAgent.Name And re-add the name to the logger so that log messages from different agents in a single can be identified.	5 years ago
Daniel Nephin	dd40a1535e	testing: reduce verbosity of output log Previously the log output included the test name twice and a long date format. The test output is already grouped by test, so adding the test name did not add any new information. The date and time are only useful to understand elapsed time, so using a short format should provide succident detail. Also fixed a bug in NewTestAgentWithFields where nil was returned instead of the test agent.	5 years ago
R.B. Boyer	6adad71125	wan federation via mesh gateways (#6884 ) This is like a Möbius strip of code due to the fact that low-level components (serf/memberlist) are connected to high-level components (the catalog and mesh-gateways) in a twisty maze of references which make it hard to dive into. With that in mind here's a high level summary of what you'll find in the patch: There are several distinct chunks of code that are affected: * new flags and config options for the server * retry join WAN is slightly different * retry join code is shared to discover primary mesh gateways from secondary datacenters * because retry join logic runs in the agent and the results of that operation for primary mesh gateways are needed in the server there are some methods like `RefreshPrimaryGatewayFallbackAddresses` that must occur at multiple layers of abstraction just to pass the data down to the right layer. * new cache type `FederationStateListMeshGatewaysName` for use in `proxycfg/xds` layers * the function signature for RPC dialing picked up a new required field (the node name of the destination) * several new RPCs for manipulating a FederationState object: `FederationState:{Apply,Get,List,ListMeshGateways}` * 3 read-only internal APIs for debugging use to invoke those RPCs from curl * raft and fsm changes to persist these FederationStates * replication for FederationStates as they are canonically stored in the Primary and replicated to the Secondaries. * a special derivative of anti-entropy that runs in secondaries to snapshot their local mesh gateway `CheckServiceNodes` and sync them into their upstream FederationState in the primary (this works in conjunction with the replication to distribute addresses for all mesh gateways in all DCs to all other DCs) * a "gateway locator" convenience object to make use of this data to choose the addresses of gateways to use for any given RPC or gossip operation to a remote DC. This gets data from the "retry join" logic in the agent and also directly calls into the FSM. * RPC (`:8300`) on the server sniffs the first byte of a new connection to determine if it's actually doing native TLS. If so it checks the ALPN header for protocol determination (just like how the existing system uses the type-byte marker). * 2 new kinds of protocols are exclusively decoded via this native TLS mechanism: one for ferrying "packet" operations (udp-like) from the gossip layer and one for "stream" operations (tcp-like). The packet operations re-use sockets (using length-prefixing) to cut down on TLS re-negotiation overhead. * the server instances specially wrap the `memberlist.NetTransport` when running with gateway federation enabled (in a `wanfed.Transport`). The general gist is that if it tries to dial a node in the SAME datacenter (deduced by looking at the suffix of the node name) there is no change. If dialing a DIFFERENT datacenter it is wrapped up in a TLS+ALPN blob and sent through some mesh gateways to eventually end up in a server's :8300 port. * a new flag when launching a mesh gateway via `consul connect envoy` to indicate that the servers are to be exposed. This sets a special service meta when registering the gateway into the catalog. * `proxycfg/xds` notice this metadata blob to activate additional watches for the FederationState objects as well as the location of all of the consul servers in that datacenter. * `xds:` if the extra metadata is in place additional clusters are defined in a DC to bulk sink all traffic to another DC's gateways. For the current datacenter we listen on a wildcard name (`server.<dc>.consul`) that load balances all servers as well as one mini-cluster per node (`<node>.server.<dc>.consul`) * the `consul tls cert create` command got a new flag (`-node`) to help create an additional SAN in certs that can be used with this flavor of federation.	5 years ago

R.B. Boyer	f9496dc627	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.	5 years ago
