Matt Keeler	326c0ecfbe	In-Memory gRPC (#19942 ) * Implement In-Process gRPC for use by controller caching/indexing This replaces the pipe base listener implementation we were previously using. The new style CAN avoid cloning resources which our controller caching/indexing is taking advantage of to not duplicate resource objects in memory. To maintain safety for controllers and for them to be able to modify data they get back from the cache and the resource service, the client they are presented in their runtime will be wrapped with an autogenerated client which clones request and response messages as they pass through the client. Another sizable change in this PR is to consolidate how server specific gRPC services get registered and managed. Before this was in a bunch of different methods and it was difficult to track down how gRPC services were registered. Now its all in one place. * Fix race in tests * Ensure the resource service is registered to the multiplexed handler for forwarding from client agents * Expose peer streaming on the internal handler	11 months ago

Dan Upton	d4c435856b	grpc: `protoc` plugin for generating gRPC rate limit specifications (#15564 ) Adds automation for generating the map of `gRPC Method Name → Rate Limit Type` used by the middleware introduced in #15550, and will ensure we don't forget to add new endpoints. Engineers must annotate their RPCs in the proto file like so: ``` rpc Foo(FooRequest) returns (FooResponse) { option (consul.internal.ratelimit.spec) = { operation_type: READ, }; } ``` When they run `make proto` a protoc plugin `protoc-gen-consul-rate-limit` will be installed that writes rate-limit specs as a JSON array to a file called `.ratelimit.tmp` (one per protobuf package/directory). After running Buf, `make proto` will execute a post-process script that will ingest all of the `.ratelimit.tmp` files and generate a Go file containing the mappings in the `agent/grpc-middleware` package. In the enterprise repository, it will write an additional file with the enterprise-only endpoints. If an engineer forgets to add the annotation to a new RPC, the plugin will return an error like so: ``` RPC Foo is missing rate-limit specification, fix it with: import "proto-public/annotations/ratelimit/ratelimit.proto"; service Bar { rpc Foo(...) returns (...) { option (hashicorp.consul.internal.ratelimit.spec) = { operation_type: OPERATION_READ \| OPERATION_WRITE \| OPERATION_EXEMPT, }; } } ``` In the future, this annotation can be extended to support rate-limit category (e.g. KV vs Catalog) and to determine the retry policy.	2 years ago

Dan Upton	b9e525d689	grpc: rename public/private directories to external/internal (#13721 ) Previously, public referred to gRPC services that are both exposed on the dedicated gRPC port and have their definitions in the proto-public directory (so were considered usable by 3rd parties). Whereas private referred to services on the multiplexed server port that are only usable by agents and other servers. Now, we're splitting these definitions, such that external/internal refers to the port and public/private refers to whether they can be used by 3rd parties. This is necessary because the peering replication API needs to be exposed on the dedicated port, but is not (yet) suitable for use by 3rd parties.	2 years ago

Daniel Nephin	1a137c29d6	grpc: fix grpc metrics 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.	4 years ago

Daniel Nephin	636f76f6f1	agent/grpc: make TestHandler_EmitsStats predictable Occasionally this test would flake. The flakes were fixed by: 1. Stopping the service and retrying to check on metrics. This way we also include the active_streams going to 0 in the metric calls. 2. Using a reference to the global Metrics. This way when other tests have background goroutines that are still shutting down, they won't emit metrics to the metric instance with the fake Sink. The stats test can patch the local reference to the global, so the existing statHandlers will continue to emit to the global, but the stats test will send all metrics to the replacement.	4 years ago
