Iryna Shustava	d747b51dab	Handle ACL errors consistently when blocking query timeout is reached. (#20876 ) Currently, when a client starts a blocking query and an ACL token expires within that time, Consul will return ACL not found error with a 403 status code. However, sometimes if an ACL token is invalidated at the same time as the query's deadline is reached, Consul will instead return an empty response with a 200 status code. This is because of the events being executed. 1. Client issues a blocking query request with timeout `t`. 2. ACL is deleted. 3. Server detects a change in ACLs and force closes the gRPC stream. 4. Client resubscribes with the same token and resets its state (view). 5. Client sees "ACL not found" error. If ACL is deleted before step 4, the client is unaware that the stream was closed due to an ACL error and will return an empty view (from the reset state) with the 200 status code. To fix this problem, we introduce another state to the subsciption to indicate when a change to ACLs has occured. If the server sees that there was an error due to ACL change, it will re-authenticate the request and return an error if the token is no longer valid. Fixes #20790	8 months ago
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

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

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
