Dan Upton	73b9b407ba	grpc: fix data race in balancer registration (#16229 ) Registering gRPC balancers is thread-unsafe because they are stored in a global map variable that is accessed without holding a lock. Therefore, it's expected that balancers are registered _once_ at the beginning of your program (e.g. in a package `init` function) and certainly not after you've started dialing connections, etc. > NOTE: this function must only be called during initialization time > (i.e. in an init() function), and is not thread-safe. While this is fine for us in production, it's challenging for tests that spin up multiple agents in-memory. We currently register a balancer per- agent which holds agent-specific state that cannot safely be shared. This commit introduces our own registry that _is_ thread-safe, and implements the Builder interface such that we can call gRPC's `Register` method once, on start-up. It uses the same pattern as our resolver registry where we use the dial target's host (aka "authority"), which is unique per-agent, to determine which builder to use.	2 years ago
Matt Keeler	085c0addc0	Protobuf Refactoring for Multi-Module Cleanliness (#16302 ) Protobuf Refactoring for Multi-Module Cleanliness This commit includes the following: Moves all packages that were within proto/ to proto/private Rewrites imports to account for the packages being moved Adds in buf.work.yaml to enable buf workspaces Names the proto-public buf module so that we can override the Go package imports within proto/buf.yaml Bumps the buf version dependency to 1.14.0 (I was trying out the version to see if it would get around an issue - it didn't but it also doesn't break things and it seemed best to keep up with the toolchain changes) Why: In the future we will need to consume other protobuf dependencies such as the Google HTTP annotations for openapi generation or grpc-gateway usage. There were some recent changes to have our own ratelimiting annotations. The two combined were not working when I was trying to use them together (attempting to rebase another branch) Buf workspaces should be the solution to the problem Buf workspaces means that each module will have generated Go code that embeds proto file names relative to the proto dir and not the top level repo root. This resulted in proto file name conflicts in the Go global protobuf type registry. The solution to that was to add in a private/ directory into the path within the proto/ directory. That then required rewriting all the imports. Is this safe? AFAICT yes The gRPC wire protocol doesn't seem to care about the proto file names (although the Go grpc code does tack on the proto file name as Metadata in the ServiceDesc) Other than imports, there were no changes to any generated code as a result of this.	2 years ago

Matt Keeler	5afd4657ec	Protobuf Modernization (#15949 ) * Protobuf Modernization Remove direct usage of golang/protobuf in favor of google.golang.org/protobuf Marshallers (protobuf and json) needed some changes to account for different APIs. Moved to using the google.golang.org/protobuf/types/known/* for the well known types including replacing some custom Struct manipulation with whats available in the structpb well known type package. This also updates our devtools script to install protoc-gen-go from the right location so that files it generates conform to the correct interfaces. * Fix go-mod-tidy make target to work on all modules	2 years ago
Dan Upton	d53ce39c32	grpc: switch servers and retry on error (#15892 ) This is the OSS portion of enterprise PR 3822. Adds a custom gRPC balancer that replicates the router's server cycling behavior. Also enables automatic retries for RESOURCE_EXHAUSTED errors, which we now get for free.	2 years 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
