Does ordering still work to specify one plugin per envoy filter

[wonderflow]

From my understanding, htnn support specify multiple plugins inside one envoy filter, so multiple plugins can have ordering features.

                http_filters:
                  - name: htnn.filters.http.golang
                    typed_config:
                      "@type": type.googleapis.com/envoy.extensions.filters.http.golang.v3alpha.Config
                      library_id: fm
                      library_path: /etc/libgolang.so
                      plugin_name: fm
                      plugin_config:
                        "@type": type.googleapis.com/xds.type.v3.TypedStruct
                        value:
                          plugins:
                            - name: plugin-1
                              config:
                                host_name: Jack
                            - name: plugin-2

My question here is, if we use multiple envoy filters like below, does the inherent ordering still work even for plugin specified in different envoy filters?

                http_filters:
                  - name: htnn.filters.http.golang
                    typed_config:
                      "@type": type.googleapis.com/envoy.extensions.filters.http.golang.v3alpha.Config
                      library_id: fm-01
                      library_path: /etc/libgolang.so
                      plugin_name: fm-01
                      plugin_config:
                        "@type": type.googleapis.com/xds.type.v3.TypedStruct
                        value:
                          plugins:
                            - name: plugin-1
                              config:
                                host_name: Jack
                  - name: htnn.filters.http.golang
                    typed_config:
                      "@type": type.googleapis.com/envoy.extensions.filters.http.golang.v3alpha.Config
                      library_id: fm-02
                      library_path: /etc/libgolang.so
                      plugin_name: fm-02
                      plugin_config:
                        "@type": type.googleapis.com/xds.type.v3.TypedStruct
                        value:
                          plugins:
                            - name: plugin-2

No, the order only applies inside the Envoy Golang filter. In fact, they are used in:

htnn/controller/internal/translation/merged_state.go

Line 360 in 3e29c94

sortPlugins(fmc.Plugins)

htnn/api/pkg/filtermanager/filtermanager.go

Line 459 in 3e29c94

sort.Slice(m.filters, func(i, j int) bool {
