This is a bit of a grab bag of helpers that I found useful for working with them when authoring substantial Controllers. Subsequent PRs will make use of them.
Configuration that previously was inlined into the Upstreams resource
applies to both explicit and implicit upstreams and so it makes sense to
split it out into its own resource.
It also has other minor changes:
- Renames `proxy.proto` proxy_configuration.proto`
- Changes the type of `Upstream.destination_ref` from `pbresource.ID` to
`pbresource.Reference`
- Adds comments to fields that didn't have them
For consistency, resource type names must follow these rules:
- `Group` must be snake case, and in most cases a single word.
- `GroupVersion` must be lowercase, start with a "v" and end with a number.
- `Kind` must be pascal case.
These were chosen because they map to our protobuf type naming
conventions.
* Implement the Catalog V2 controller integration container tests
This now allows the container tests to import things from the root module. However for now we want to be very restrictive about which packages we allow importing.
* Add an upgrade test for the new catalog
Currently this should be dormant and not executed. However its put in place to detect breaking changes in the future and show an example of how to do an upgrade test with integration tests structured like catalog v2.
* Make testutil.Retry capable of performing cleanup operations
These cleanup operations are executed after each retry attempt.
* Move TestContext to taking an interface instead of a concrete testing.T
This allows this to be used on a retry.R or generally anything that meets the interface.
* Move to using TestContext instead of background contexts
Also this forces all test methods to implement the Cleanup method now instead of that being an optional interface.

* Implement a Catalog Controllers Lifecycle Integration Test
* Prevent triggering the race detector.
This allows defining some variables for protobuf constants and using those in comparisons. Without that, something internal in the fmt package ended up looking at the protobuf message size cache and triggering the race detector.
* Add a ReplaceType dep mapper and move them into their own file
* Implement the service endpoints controller
* Implement a Catalog Controllers Integration Test
TLDR with many modules the versions included in each diverged quite a bit. Attempting to use Go Workspaces produces a bunch of errors.
This commit:
1. Fixes envoy-library-references.sh to work again
2. Ensures we are pulling in go-control-plane@v0.11.0 everywhere (previously it was at that version in some modules and others were much older)
3. Remove one usage of golang/protobuf that caused us to have a direct dependency on it.
4. Remove deprecated usage of the Endpoint field in the grpc resolver.Target struct. The current version of grpc (v1.55.0) has removed that field and recommended replacement with URL.Opaque and calls to the Endpoint() func when needing to consume the previous field.
4. `go work init <all the paths to go.mod files>` && `go work sync`. This syncrhonized versions of dependencies from the main workspace/root module to all submodules
5. Updated .gitignore to ignore the go.work and go.work.sum files. This seems to be standard practice at the moment.
6. Update doc comments in protoc-gen-consul-rate-limit to be go fmt compatible
7. Upgraded makefile infra to perform linting, testing and go mod tidy on all modules in a flexible manner.
8. Updated linter rules to prevent usage of golang/protobuf
9. Updated a leader peering test to account for an extra colon in a grpc error message.
* Fix straggler from renaming Register->RegisterTypes
* somehow a lint failure got through previously
* Fix lint-consul-retry errors
* adding in fix for success jobs getting skipped. (#17132)
* Temporarily disable inmem backend conformance test to get green pipeline
* Another test needs disabling

Introduces `storage.Backend`, which will serve as the interface between the
Resource Service and the underlying storage system (Raft today, but in the
future, who knows!).
The primary design goal of this interface is to keep its surface area small,
and push as much functionality as possible into the layers above, so that new
implementations can be added with little effort, and easily proven to be
correct. To that end, we also provide a suite of "conformance" tests that can
be run against a backend implementation to check it behaves correctly.
In this commit, we introduce an initial in-memory storage backend, which is
suitable for tests and when running Consul in development mode. This backend is
a thin wrapper around the `Store` type, which implements a resource database
using go-memdb and our internal pub/sub system. `Store` will also be used to
handle reads in our Raft backend, and in the future, used as a local cache for
external storage systems.
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.
* 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
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.
* update go version to 1.18 for api and sdk, go mod tidy
* removes ioutil usage everywhere which was deprecated in go1.16 in favour of io and os packages. Also introduces a lint rule which forbids use of ioutil going forward.
