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.
There are a few changes that needed to be made to to handle authorizing
reads for imported data:
- If the data was imported from a peer we should not attempt to read the
data using the traditional authz rules. This is because the name of
services/nodes in a peer cluster are not equivalent to those of the
importing cluster.
- If the data was imported from a peer we need to check whether the
token corresponds to a service, meaning that it has service:write
permissions, or to a local read only token that can read all
nodes/services in a namespace.
This required changes at the policyAuthorizer level, since that is the
only view available to OSS Consul, and at the enterprise
partition/namespace level.
This is the OSS portion of enterprise PR 2242.
This PR introduces a server-local implementation of the proxycfg.ServiceList
interface, backed by streaming events and a local materializer.
This is the OSS portion of enterprise PR 2056.
This commit provides server-local implementations of the proxycfg.ConfigEntry
and proxycfg.ConfigEntryList interfaces, that source data from streaming events.
It makes use of the LocalMaterializer type introduced for peering replication,
adding the necessary support for authorization.
It also adds support for "wildcard" subscriptions (within a topic) to the event
publisher, as this is needed to fetch service-resolvers for all services when
configuring mesh gateways.
Currently, events will be emitted for just the ingress-gateway, service-resolver,
and mesh config entry types, as these are the only entries required by proxycfg
— the events will be emitted on topics named IngressGateway, ServiceResolver,
and MeshConfig topics respectively.
Though these events will only be consumed "locally" for now, they can also be
consumed via the gRPC endpoint (confirmed using grpcurl) so using them from
client agents should be a case of swapping the LocalMaterializer for an
RPCMaterializer.
Previously we had 1 EventPublisher per state.Store. When a state store was closed/abandoned such as during a consul snapshot restore, this had the behavior of force closing subscriptions for that topic and evicting event snapshots from the cache.
The intention of this commit is to keep all that behavior. To that end, the shared EventPublisher now supports the ability to refresh a topic. That will perform the force close + eviction. The FSM upon abandoning the previous state.Store will call RefreshTopic for all the topics with events generated by the state.Store.
Adds a new gRPC streaming endpoint (WatchRoots) that dataplane clients will
use to fetch the current list of active Connect CA roots and receive new
lists whenever the roots are rotated.
Many places in consul already treated node names case insensitively.
The state store indexes already do it, but there are a few places that
did a direct byte comparison which have now been corrected.
One place of particular consideration is ensureCheckIfNodeMatches
which is executed during snapshot restore (among other places). If a
node check used a slightly different casing than the casing of the node
during register then the snapshot restore here would deterministically
fail. This has been fixed.
Primary approach:
git grep -i "node.*[!=]=.*node" -- ':!*_test.go' ':!docs'
git grep -i '\[[^]]*member[^]]*\]
git grep -i '\[[^]]*\(member\|name\|node\)[^]]*\]' -- ':!*_test.go' ':!website' ':!ui' ':!agent/proxycfg/testing.go:' ':!*.md'
I added this recently without realizing that the method already existed and was named
NamespaceOrEmpty. Replace all calls to GetNamespace with NamespaceOrEmpty or NamespaceOrDefault
as appropriate.
Refactored out a function that can be used for both the snapshot and stream of events to translate
an event into an appropriate connect event.
Previously terminating gateway events would have used the wrong key in the snapshot, which would have
caused them to be filtered out later on.
Also removed an unused function, and some commented out code.
Health of a terminating gateway instance changes
- Generate an event for creating/destroying this instance of the terminating gateway,
duplicate it for each affected service

Makes Payload a type with FilterByKey so that Payloads can implement
filtering by key. With this approach we don't need to expose a Namespace
field on Event, and we don't need to invest micro formats or require a
bunch of code to be aware of exactly how the key field is encoded.
The subscribe endpoint needs to be able to inspect the payload to filter
events, and convert them into the protobuf types.
Use the protobuf CatalogOp type for the operation field, for now. In the
future if we end up with multiple interfaces we should be able to remove
the protobuf dependency by changing this to an int32 and adding a test
for the mapping between the values.
Make the value of the payload a concrete type instead of interface{}. We
can create other payloads for other event types.
