🧩 Analysis chain
Fix build error in NewReplicationServer call.
The PR correctly adds the HTTP address parameter to the server initialization, but the build is failing. This suggests there might be a mismatch between the changes in this file and the server constructor implementation.
🏁 Script executed:
#!/bin/bash # Verify NewReplicationServer function signature rg -A 5 "func NewReplicationServer\(" pkg/server/Length of output: 331
Action Required: Fix Build Signature Mismatch in NewReplicationServer Call
Issue: The call in
cmd/replication/main.go(line 120) is passing an extra parameter generated byfmt.Sprintf("0.0.0.0:%d", options.API.HTTPPort),which appears to represent the HTTP address. However, the
NewReplicationServerfunction inpkg/server/server.goonly accepts the following parameters:
ctx context.Contextlog *zap.Loggeroptions config.ServerOptionsnodeRegistry registry.NodeRegistrywriterDB *sql.DBThis mismatch is triggering the build error.
Recommendation:
Please update the call toNewReplicationServerincmd/replication/main.goto match the constructor's signature. This may involve:
- Removing the HTTP address parameter if it is not needed; or
- Modifying the constructor in
pkg/server/server.goto accept the new parameter if the HTTP address is required for proper initialization.pkg/api/http_server.go (2)
46-55:
⚠️ Potential issuePotential nil pointer dereference risk
The code checks for a nil
httpListeneronly after it has already been used to log the address in line 47. IfhttpListeneris nil, this will cause a panic.Move the nil check before using the listener:
tracing.GoPanicWrap(s.ctx, &s.wg, "http", func(ctx context.Context) { - s.log.Info("serving http", zap.String("address", s.httpListener.Addr().String())) if s.httpListener == nil { s.log.Fatal("no http listener") } + s.log.Info("serving http", zap.String("address", s.httpListener.Addr().String())) err = gwServer.Serve(s.httpListener) if err != nil && err != http.ErrServerClosed && !isErrUseOfClosedConnection(err) { s.log.Error("serving http", zap.Error(err)) } })📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation.

165-186: 🛠️ Refactor suggestion
Initialize the error variable before use
The function uses the
errvariable without first initializing it in the function scope. It's reusing a variable from a wider scope, which can lead to bugs if the variable has unexpected values.Explicitly declare and initialize the error variable:
httpRegistrationFunc := func(gwmux *runtime.ServeMux, conn *grpc.ClientConn) error { + var err error err = metadata_api.RegisterMetadataApiHandler(ctx, gwmux, conn) log.Info("Metadata http gateway enabled") if err != nil { return err } err = message_api.RegisterReplicationApiHandler(ctx, gwmux, conn) log.Info("Replication http gateway enabled") if err != nil { return err } err = payer_api.RegisterPayerApiHandler(ctx, gwmux, conn) log.Info("Payer http gateway enabled") if err != nil { return err } return nil }📝 Committable suggestion

⚠️ Potential issueFix undefined 'log' variable in httpRegistrationFunc
Static analysis and pipeline failures show that the
logvariable is undefined within thehttpRegistrationFuncscope. This will cause compilation errors.Use the properly scoped logger from the function parameters:
httpRegistrationFunc := func(gwmux *runtime.ServeMux, conn *grpc.ClientConn) error { + var err error if options.Replication.Enable { err = metadata_api.RegisterMetadataApiHandler(ctx, gwmux, conn) - log.Info("Metadata http gateway enabled") + log.Info("Metadata http gateway enabled") if err != nil { return err } err = message_api.RegisterReplicationApiHandler(ctx, gwmux, conn) - log.Info("Replication http gateway enabled") + log.Info("Replication http gateway enabled") if err != nil { return err } } if options.Payer.Enable { err = payer_api.RegisterPayerApiHandler(ctx, gwmux, conn) - log.Info("Payer http gateway enabled") + log.Info("Payer http gateway enabled") if err != nil { return err } } return nil }Note: While
logis already passed into the outer function and might be accessible here, it's better practice to explicitly reference it to avoid confusion.Committable suggestion skipped: line range outside the PR's diff.

pkg/server/server_test.go (7)
46-46: New parameter correctly added.The addition of the
httpPortparameter enhances the test server to support HTTP alongside gRPC. This aligns well with the PR objectives of adding gRPC-gateway functionality.
65-67: Config structure updated correctly.The API configuration now includes both the gRPC port and HTTP port, which is necessary for the dual-protocol support introduced in this PR.
74-74: Server creation updated with HTTP address.The
NewReplicationServercall has been properly updated to include the HTTP address parameter.
95-98: HTTP port allocation added correctly.The test now allocates separate ports for both gRPC and HTTP servers, ensuring they don't conflict.
139-140: Test server creation updated consistently.The test now correctly initializes both servers with their respective gRPC and HTTP ports.
234-236: HTTP port allocation added to second test.Good consistency - the HTTP port allocation is added to all relevant test functions.
258-258: Test server creation updated consistently.The update to pass the HTTP port has been consistently applied to all test server instances.
pkg/api/http_server.go (7)
18-18: Good design for HTTP registration.The
HttpRegistrationFunctype is a well-designed function signature that allows for flexible registration of gRPC services with the HTTP gateway.
27-31: Issue with error handling in case of dialing failure.When
DialGRPCfails, you're usinglog.Fatalwhich will terminate the program, but also returning the error. The return value becomes redundant since the program would exit.Consider either:
- Use
log.Errorand return the error, allowing the caller to handle it- Use
log.Fataland don't return (though this is generally not recommended)- if err != nil { - log.Fatal("dialing GRPC from HTTP Gateway") - return err - } + if err != nil { + log.Error("failed dialing GRPC from HTTP Gateway", zap.Error(err)) + return err + }
35-40: Good configuration of HTTP gateway.The setup includes proper marshaller options, error handling, and health endpoint integration.
45-48: Good server setup with CORS support.The HTTP server is properly configured with the CORS middleware.
56-58: Comprehensive error handling.The error handling is thorough, distinguishing between different types of errors (server closed, connection closed, etc.).
64-84: Well-implemented CORS preflight handler.The preflight handler correctly handles the required headers for a wide range of clients, improving cross-origin compatibility.
86-95: Good CORS middleware implementation.The middleware properly handles both preflight OPTIONS requests and normal requests by setting the right headers.

ApiServerstruct to maintain the HTTP listener alongside the gRPC listener.

59-62: Good error handling for HTTP listener.The error handling for the HTTP listener creation follows the same pattern as for the gRPC listener.
70-70: HTTP listener added to ApiServer struct.The HTTP listener is properly initialized in the struct.
137-137: HTTP server started.The HTTP server is properly started using the
startHTTPmethod.
151-153: Getter method for HTTP address added.Adding the
HttpAddrmethod is a good addition that follows the pattern of the existingAddrmethod.
188-194: HTTP listener cleanup added.The
Closemethod has been properly updated to clean up the HTTP listener, following the same pattern as the gRPC listener cleanup.pkg/server/server.go (4)
65-65: Parameter added for HTTP address.The
NewReplicationServerfunction signature has been updated to include the HTTP address parameter.
143-143: HTTP address passed to API server.The
httpListenAddressis correctly passed to thestartAPIServerfunction.
178-178: API server function updated for HTTP support.The
startAPIServerfunction signature has been updated to accept the HTTP address.
318-321: API server creation updated for HTTP support.The
NewAPIServercall has been properly updated to include the HTTP address and registration function.
