Ronald	94ec4eb2f4	copyright headers for agent folder (#16704 ) * copyright headers for agent folder * Ignore test data files * fix proto files and remove headers in agent/uiserver folder * ignore deep-copy files	2 years ago
Daniel Nephin	b9e60c0775	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. See https://github.com/gotestyourself/gotestsum#finding-and-skipping-slow-tests With this change: ``` $ time go test -count=1 -short ./agent ok github.com/hashicorp/consul/agent 0.743s real 0m4.791s $ time go test -count=1 -short ./agent/consul ok github.com/hashicorp/consul/agent/consul 4.229s real 0m8.769s ```	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	07b4507f1e	router: remove grpcServerTracker from managers It only needs to be refereced from the Router, because there is only 1 instance, and the Router can call AddServer/RemoveServer like it does on the Manager.	4 years ago

Hans Hasselberg	c45432014b	pool: remove version The version field has been used to decide which multiplexing to use. It was introduced in `2457293dce`. But this is 6y ago and there is no need for this differentiation anymore.	5 years ago
Daniel Nephin	c88fae0aac	ci: Add staticcheck and fix most errors Three of the checks are temporarily disabled to limit the size of the diff, and allow us to enable all the other checks in CI. In a follow up we can fix the issues reported by the other checks one at a time, and enable them.	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
