From 4c20691eb4e0fd1dadbd8ffeb108f442f4e9d83f Mon Sep 17 00:00:00 2001 From: yuanyuyuan Date: Thu, 7 May 2026 13:45:34 +0000 Subject: [PATCH 01/48] =?UTF-8?q?feat:=20add=20ros-z-bridge-ros2dds=20?= =?UTF-8?q?=E2=80=94=20native=20DDS=E2=86=94Zenoh=20bridge?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Bridges DDS-based ROS 2 nodes (rmw_cyclonedds_cpp) to a Zenoh/ros-z network without requiring any ROS 2 packages on the bridge host. Uses cyclors 0.2.7 to build CycloneDDS from source and forward raw CDR bytes between DDS and Zenoh, no deserialization needed. Key design points: - RAII DdsEntity wrapper ensures dds_delete on drop (fixes ghost subscribers) - Stable client_guid derived from participant instance handle (not per-writer) - Push-based discovery via DDS builtin topic listeners - Four route types: DdsToZenoh, ZenohToDds, ServiceRoute, ServiceCliRoute - Namespace isolation via --namespace flag (ros2_name_to_zenoh_key) - Allow/deny regex filtering for topic bridging Integration tests in ros-z-tests cover all six scenarios from the zenoh-plugin-ros2dds test suite: pub/sub (both directions), services (both directions), and actions (both directions). CI job added for Jazzy + CycloneDDS container. --- .github/workflows/test.yml | 52 ++ Cargo.lock | 119 +++- Cargo.toml | 1 + crates/ros-z-bridge-ros2dds/Cargo.toml | 31 + crates/ros-z-bridge-ros2dds/src/bridge.rs | 193 ++++++ crates/ros-z-bridge-ros2dds/src/config.rs | 32 + .../ros-z-bridge-ros2dds/src/dds/discovery.rs | 161 +++++ crates/ros-z-bridge-ros2dds/src/dds/entity.rs | 33 + crates/ros-z-bridge-ros2dds/src/dds/gid.rs | 33 + crates/ros-z-bridge-ros2dds/src/dds/mod.rs | 9 + crates/ros-z-bridge-ros2dds/src/dds/names.rs | 132 ++++ .../src/dds/participant.rs | 35 + crates/ros-z-bridge-ros2dds/src/dds/qos.rs | 95 +++ crates/ros-z-bridge-ros2dds/src/dds/reader.rs | 85 +++ crates/ros-z-bridge-ros2dds/src/dds/types.rs | 56 ++ crates/ros-z-bridge-ros2dds/src/dds/writer.rs | 85 +++ crates/ros-z-bridge-ros2dds/src/main.rs | 36 + .../ros-z-bridge-ros2dds/src/routes/action.rs | 16 + crates/ros-z-bridge-ros2dds/src/routes/mod.rs | 4 + .../ros-z-bridge-ros2dds/src/routes/pubsub.rs | 125 ++++ .../src/routes/service.rs | 162 +++++ .../src/routes/service_cli.rs | 158 +++++ crates/ros-z-tests/Cargo.toml | 3 + crates/ros-z-tests/tests/ros2dds_bridge.rs | 628 ++++++++++++++++++ 24 files changed, 2280 insertions(+), 4 deletions(-) create mode 100644 crates/ros-z-bridge-ros2dds/Cargo.toml create mode 100644 crates/ros-z-bridge-ros2dds/src/bridge.rs create mode 100644 crates/ros-z-bridge-ros2dds/src/config.rs create mode 100644 crates/ros-z-bridge-ros2dds/src/dds/discovery.rs create mode 100644 crates/ros-z-bridge-ros2dds/src/dds/entity.rs create mode 100644 crates/ros-z-bridge-ros2dds/src/dds/gid.rs create mode 100644 crates/ros-z-bridge-ros2dds/src/dds/mod.rs create mode 100644 crates/ros-z-bridge-ros2dds/src/dds/names.rs create mode 100644 crates/ros-z-bridge-ros2dds/src/dds/participant.rs create mode 100644 crates/ros-z-bridge-ros2dds/src/dds/qos.rs create mode 100644 crates/ros-z-bridge-ros2dds/src/dds/reader.rs create mode 100644 crates/ros-z-bridge-ros2dds/src/dds/types.rs create mode 100644 crates/ros-z-bridge-ros2dds/src/dds/writer.rs create mode 100644 crates/ros-z-bridge-ros2dds/src/main.rs create mode 100644 crates/ros-z-bridge-ros2dds/src/routes/action.rs create mode 100644 crates/ros-z-bridge-ros2dds/src/routes/mod.rs create mode 100644 crates/ros-z-bridge-ros2dds/src/routes/pubsub.rs create mode 100644 crates/ros-z-bridge-ros2dds/src/routes/service.rs create mode 100644 crates/ros-z-bridge-ros2dds/src/routes/service_cli.rs create mode 100644 crates/ros-z-tests/tests/ros2dds_bridge.rs diff --git a/.github/workflows/test.yml b/.github/workflows/test.yml index f3addd7c..bc81e71c 100644 --- a/.github/workflows/test.yml +++ b/.github/workflows/test.yml @@ -116,3 +116,55 @@ jobs: --features ros-interop --release \ -E 'test(dynamic_subscriber)' fi + + ros2dds_bridge_test: + name: ros-z-bridge-ros2dds integration tests (Jazzy / CycloneDDS) + runs-on: ubuntu-latest + if: | + github.event_name == 'push' || + github.event.pull_request.draft == false + container: + image: ros:jazzy-ros-base + steps: + -

cache size = history.depth x 10 - Add is_reliable / is_transient_local helpers to qos.rs Action get_result timeout: - ServiceCliRoute uses 300 s querier timeout for _action/get_result topics (up from 10 s) to match zenoh-plugin-ros2dds DEFAULT_ACTION_GET_RESULT_TIMEOUT - Add is_action_get_result_topic() to names.rs Config improvements: - --domain-id now defaults to ROS_DOMAIN_ID env var, falling back to 0 - --reliable-routes-blocking flag (default true) - Per-type allow/deny regexes: --allow-pub, --deny-pub, --allow-sub, --deny-sub, --allow-service-srv, --deny-service-srv, --allow-service-cli, --deny-service-cli;

CycloneDDS echoes the writer handle back as client_guid in the reply, so using the participant handle caused reply routing mismatches. - (#647) Strip the 16-byte CddsRequestHeader (guid + seq_num) from DDS replies before forwarding to Zenoh. The Zenoh querier sent [CDR_HDR + payload] and expects the same shape back. - (#642) Add .complete(true) to the service queryable so Zenoh routers recognise this bridge as a complete service provider, enabling cross-router service calls to succeed. - (#542) Add .allowed_destination(Locality::Remote) to all DDS→Zenoh publishers so the bridge does not re-deliver its own publications to Zenoh subscribers on the same session, preventing routing loops when two bridge instances share a session and DDS domain. Adds 5 unit tests covering sequence number extraction, reply header stripping, and request payload construction. --- crates/ros-z-bridge-ros2dds/src/bridge.rs | 8 +- .../ros-z-bridge-ros2dds/src/routes/pubsub.rs | 5 + .../src/routes/service.rs | 120 ++++++++++++++++-- 3 files changed, 117 insertions(+), 16 deletions(-) diff --git a/crates/ros-z-bridge-ros2dds/src/bridge.rs b/crates/ros-z-bridge-ros2dds/src/bridge.rs index d1954700..afc112b3 100644 --- a/crates/ros-z-bridge-ros2dds/src/bridge.rs +++ b/crates/ros-z-bridge-ros2dds/src/bridge.rs @@ -11,7 +11,7 @@ use crate::{ entity::DdsEntity, gid::Gid, names::{is_pubsub_topic, is_request_topic}, - participant::{create_participant, get_instance_handle}, + participant::create_participant, }, routes::{ pubsub::{DdsToZenohRoute, ZenohToDdsRoute}, @@ -61,9 +61,6 @@ pub struct Bridge { config: Config, session: Session, participant: DdsEntity, - /// Stable u64 derived from the participant instance handle.

charset=UTF-8 Content-Transfer-Encoding: 8bit G1 (TRANSIENT_LOCAL churn, #690): split DDS→Zenoh route into a shared TopicPublisherSlot (Arc, keyed by (domain_id, topic_name)) and a per-writer DdsToZenohRoute. Undiscovery starts a 5 s grace period before evicting the slot so AdvancedPublisher history cache survives rapid DDS participant restarts. G2 (action filtering): add --allow-action / --deny-action CLI flags; bridge dispatcher calls is_action_component() first and applies the action filter before the per-type pub/sub/service filters. G3 (QoS mismatch reporting): add qos_mismatch_reason(writer, reader) to dds/qos.rs; log WARN at route creation when BEST_EFFORT writer meets RELIABLE reader, or VOLATILE writer meets TRANSIENT_LOCAL reader. G4 (type name attachment): attach the ROS 2 type name (UTF-8 bytes) as a Zenoh publication attachment on every DDS→Zenoh message via BridgePublisherInner::put_wait(bytes, Some(ros2_type)). G5 (liveliness key builder): add liveliness.rs with build_node_lv_key / build_entity_lv_key following the @ros2_lv/... format; mod declared in main.rs for future token publication. G6 (multi-domain bridging): --domain-id may be repeated; bridge creates one CycloneDDS participant per domain, merges discovery channels into one tagged stream, and keys all route maps by (domain_id, Gid) to prevent GID collisions across domains. G7 (TLS transport): add --zenoh-config-file flag; main.rs loads the JSON5 file before overlaying the --zenoh-endpoint; Cargo.toml adds the transport_tls Zenoh feature. All 61 unit tests pass. --- crates/ros-z-bridge-ros2dds/Cargo.toml | 2 +- crates/ros-z-bridge-ros2dds/src/bridge.rs | 287 +++++++++++++++--- crates/ros-z-bridge-ros2dds/src/config.rs | 46 ++- crates/ros-z-bridge-ros2dds/src/dds/qos.rs | 77 +++++ crates/ros-z-bridge-ros2dds/src/liveliness.rs | 209 +++++++++++++ crates/ros-z-bridge-ros2dds/src/main.rs | 9 +- .../ros-z-bridge-ros2dds/src/routes/pubsub.rs | 230 +++++++++++--- 7 files changed, 767 insertions(+), 93 deletions(-) create mode 100644 crates/ros-z-bridge-ros2dds/src/liveliness.rs diff --git a/crates/ros-z-bridge-ros2dds/Cargo.toml b/crates/ros-z-bridge-ros2dds/Cargo.toml index 910ab576..c2162fc0 100644 --- a/crates/ros-z-bridge-ros2dds/Cargo.toml +++ b/crates/ros-z-bridge-ros2dds/Cargo.toml @@ -12,7 +12,7 @@ path = "src/main.rs" cyclors = "=0.2.7" ros-z = { path = "../ros-z" } ros-z-protocol = { path = "../ros-z-protocol", features = ["std", "rmw-zenoh"] } -zenoh = { workspace = true } +zenoh = { workspace = true, features = ["transport_tls"] } zenoh-ext = { workspace = true } tokio = { workspace = true, features = ["rt-multi-thread", "macros", "sync"] } diff --git a/crates/ros-z-bridge-ros2dds/src/bridge.rs b/crates/ros-z-bridge-ros2dds/src/bridge.rs index afc112b3..683ac6b8 100644 --- a/crates/ros-z-bridge-ros2dds/src/bridge.rs +++ b/crates/ros-z-bridge-ros2dds/src/bridge.rs @@ -1,6 +1,10 @@ -use std::collections::HashMap;

charset=UTF-8 Content-Transfer-Encoding: 8bit G3: add QoS mismatch warning to service and service_cli routes — both now call qos_mismatch_reason() after service_default_qos() so RELIABLE/TRANSIENT_LOCAL incompatibilities surface in logs. G5: fix liveliness key format in liveliness.rs — entity kind codes corrected to MP/MS/SS/SC (were pub/sub/srv/cli); node key format now uses /{node_id}/{node_id}/NN/%/ matching the ros-z-protocol spec; enclave segment hardcoded to '%' and removed from build_entity_lv_key signature; tests updated to assert correct format. TRANSIENT_LOCAL subscriber: ZenohToDdsRoute now uses an AdvancedSubscriber with HistoryConfig::default().detect_late_publishers() when the discovered DDS reader has TRANSIENT_LOCAL durability, so late-joining DDS readers receive historical samples from Zenoh publishers. --- crates/ros-z-bridge-ros2dds/src/liveliness.rs | 91 +++++++++++-------- .../ros-z-bridge-ros2dds/src/routes/pubsub.rs | 69 +++++++++++--- .../src/routes/service.rs | 7 +- .../src/routes/service_cli.rs | 7 +- 4 files changed, 119 insertions(+), 55 deletions(-) diff --git a/crates/ros-z-bridge-ros2dds/src/liveliness.rs b/crates/ros-z-bridge-ros2dds/src/liveliness.rs index b124009c..fe1d7894 100644 --- a/crates/ros-z-bridge-ros2dds/src/liveliness.rs +++ b/crates/ros-z-bridge-ros2dds/src/liveliness.rs @@ -4,7 +4,8 @@ /// `ros2 topic list`, and `ros2 service list` see bridged entities. /// /// Key format (from ros-z-protocol): -/// `@ros2_lv/{domain_id}/{zid}/{node_id}/{entity_id}/{kind}/{enclave}/{ns}/{name}/{topic}/{type}/{hash}/{qos}` +/// Node: `@ros2_lv/{domain_id}/{zid}/{node_id}/{node_id}/NN/%/{ns}/{name}` +/// Entity: `@ros2_lv/{domain_id}/{zid}/{node_id}/{entity_id}/{kind}/%/{ns}/{node_name}/{topic}/{type}/{hash}/{qos}` const LIVELINESS_PREFIX: &str = "@ros2_lv";

Declares per-entity liveliness tokens (MP/MS/SS/SC) whenever a route is created and drops them on undiscovery, keeping the ROS 2 graph consistent with the current set of active bridged routes. declare_entity_token() is non-fatal: a warning is logged and the route is still stored if Zenoh liveliness is unavailable, so the bridge continues to forward data even when graph visibility fails. Also adds 10 unit tests covering qos_str selection, type name dispatch (pub/sub vs service), counter monotonicity, and key format assertions for all four entity kinds. --- crates/ros-z-bridge-ros2dds/src/bridge.rs | 274 +++++++++++++++++++++- 1 file changed, 272 insertions(+), 2 deletions(-) diff --git a/crates/ros-z-bridge-ros2dds/src/bridge.rs b/crates/ros-z-bridge-ros2dds/src/bridge.rs index 683ac6b8..95785bf8 100644 --- a/crates/ros-z-bridge-ros2dds/src/bridge.rs +++ b/crates/ros-z-bridge-ros2dds/src/bridge.rs @@ -6,7 +6,7 @@ use std::{ use anyhow::Result;

charset=UTF-8 Content-Transfer-Encoding: 8bit Replace the ros-z-protocol liveliness key format with the exact key expression format used by zenoh-plugin-ros2dds so that ros-z-bridge-ros2dds tokens are visible to the existing plugin ecosystem: @/{zid}/@ros2_lv/{MP|MS|SS|SC}/{ke}/{type}[/{qos}] Where ke and type use § (U+00A7) as the slash replacement. QoS is encoded as integer discriminants matching the plugin's qos_to_key_expr format. Service tokens carry no QoS suffix. Remove node-level liveliness tokens (not part of the plugin protocol) and the entity_counter / node_id fields they required. --- crates/ros-z-bridge-ros2dds/src/bridge.rs | 200 +++------ crates/ros-z-bridge-ros2dds/src/liveliness.rs | 423 +++++++++++------- 2 files changed, 316 insertions(+), 307 deletions(-) diff --git a/crates/ros-z-bridge-ros2dds/src/bridge.rs b/crates/ros-z-bridge-ros2dds/src/bridge.rs index 95785bf8..13373470 100644 --- a/crates/ros-z-bridge-ros2dds/src/bridge.rs +++ b/crates/ros-z-bridge-ros2dds/src/bridge.rs @@ -16,12 +16,13 @@ use crate::{ gid::Gid, names::{ dds_topic_to_ros2_name, dds_type_to_ros2_service_type, dds_type_to_ros2_type, - is_pubsub_topic, is_request_topic, + is_pubsub_topic, is_request_topic, ros2_name_to_zenoh_key, }, participant::create_participant, - qos::is_reliable, }, - liveliness::{EntityKind, build_entity_lv_key, build_node_lv_key}, + liveliness::{ + build_pub_lv_key, build_service_cli_lv_key, build_service_srv_lv_key, build_sub_lv_key, + }, routes::{ action::is_action_component, pubsub::{DdsToZenohRoute, TopicPublisherSlot, ZenohToDdsRoute}, @@ -63,6 +64,13 @@ impl Filter { } } +enum EntityKind { + Publisher, + Subscriber, + ServiceServer, + ServiceClient, +} + /// Top-level bridge state. /// /// Holds all active routes keyed by (domain_id, DDS endpoint GID). @@ -97,12 +105,6 @@ pub struct Bridge { // ── Liveliness ──────────────────────────────────────────────────────────── /// Zenoh session ID string, used as a key component in liveliness tokens. zid: String, - /// Virtual bridge node id (fixed at 1;

It strips all five action-specific DDS type suffixes before the standard dds_type_to_ros2_type conversion: _SendGoal_{Request,Response}_, _GetResult_{Request,Response}_, _FeedbackMessage_ Without this, action topics would produce malformed type strings in liveliness tokens (e.g. Fibonacci/SendGoal instead of Fibonacci). Wire it into declare_entity_token: action components (detected via is_action_component on the ros2_name) use dds_type_to_ros2_action_type for all four entity kinds instead of the service/message variants. --- crates/ros-z-bridge-ros2dds/src/bridge.rs | 29 +++++++-- crates/ros-z-bridge-ros2dds/src/dds/names.rs | 64 ++++++++++++++++++++ 2 files changed, 87 insertions(+), 6 deletions(-) diff --git a/crates/ros-z-bridge-ros2dds/src/bridge.rs b/crates/ros-z-bridge-ros2dds/src/bridge.rs index 13373470..2811ef32 100644 --- a/crates/ros-z-bridge-ros2dds/src/bridge.rs +++ b/crates/ros-z-bridge-ros2dds/src/bridge.rs @@ -15,8 +15,8 @@ use crate::{ entity::DdsEntity, gid::Gid, names::{ - dds_topic_to_ros2_name, dds_type_to_ros2_service_type, dds_type_to_ros2_type, - is_pubsub_topic, is_request_topic, ros2_name_to_zenoh_key, + dds_topic_to_ros2_name, dds_type_to_ros2_action_type, dds_type_to_ros2_service_type, + dds_type_to_ros2_type, is_pubsub_topic, is_request_topic, ros2_name_to_zenoh_key, }, participant::create_participant, }, @@ -428,10 +428,15 @@ impl Bridge { let ros2_name = dds_topic_to_ros2_name(&endpoint.topic_name) .unwrap_or_else(|| endpoint.topic_name.clone()); let zenoh_ke = ros2_name_to_zenoh_key(&ros2_name, self.config.namespace.as_deref()); + let is_action = is_action_component(&ros2_name); let key = match kind { EntityKind::Publisher => { - let ros2_type = dds_type_to_ros2_type(&endpoint.type_name); + let ros2_type = if is_action { + dds_type_to_ros2_action_type(&endpoint.type_name) + } else { + dds_type_to_ros2_type(&endpoint.type_name) + }; build_pub_lv_key( &self.zid, &zenoh_ke, @@ -441,7 +446,11 @@ impl Bridge { ) } EntityKind::Subscriber => { - let ros2_type = dds_type_to_ros2_type(&endpoint.type_name); + let ros2_type = if is_action { + dds_type_to_ros2_action_type(&endpoint.type_name) + } else { + dds_type_to_ros2_type(&endpoint.type_name) + }; build_sub_lv_key( &self.zid, &zenoh_ke, @@ -451,11 +460,19 @@ impl Bridge { ) } EntityKind::ServiceServer => { - let ros2_type = dds_type_to_ros2_service_type(&endpoint.type_name); + let ros2_type = if is_action { + dds_type_to_ros2_action_type(&endpoint.type_name) + } else { + dds_type_to_ros2_service_type(&endpoint.type_name) + }; build_service_srv_lv_key(&self.zid, &zenoh_ke, &ros2_type) } EntityKind::ServiceClient => { - let ros2_type = dds_type_to_ros2_service_type(&endpoint.type_name); + let ros2_type = if is_action { + dds_type_to_ros2_action_type(&endpoint.type_name) + } else { + dds_type_to_ros2_service_type(&endpoint.type_name) + }; build_service_cli_lv_key(&self.zid, &zenoh_ke, &ros2_type) } }; diff --git a/crates/ros-z-bridge-ros2dds/src/dds/names.rs b/crates/ros-z-bridge-ros2dds/src/dds/names.rs index 03f0bf0a..5397d601 100644 --- a/crates/ros-z-bridge-ros2dds/src/dds/names.rs +++ b/crates/ros-z-bridge-ros2dds/src/dds/names.rs @@ -68,6 +68,23 @@ pub fn dds_type_to_ros2_service_type(dds_type: &str) -> String { ) } +/// Strip the action-specific suffix and convert to a ROS 2 action type. +/// +/// Mirrors `dds_type_to_ros2_action_type` from zenoh-plugin-ros2dds.

charset=UTF-8 Content-Transfer-Encoding: 8bit Replace the monolithic ros-z-bridge-ros2dds crate with a minimal zenoh-bridge-dds binary (ros-z-bridge-dds) that delegates all bridge logic to the ros-z-dds library: main.rs (~40 lines): ZContextBuilder + ZNode + ZDdsBridge::new(node, participant).run() config.rs: simplified CLI — single --domain-id, --allow, --deny, --node-name, timeout and cache multiplier flags. Delete ros-z-bridge-ros2dds/src/{bridge,liveliness,wire_format,routes/,dds/} — all logic now lives in ros-z-dds.

A route persists until all sources retire, so federation routes survive local DDS endpoint churn. Also fix liveliness key expressions to always include the type name: when type_hash is None, use TypeHash::zero() as placeholder so remote bridges can reconstruct DDS entities for the correct message type. Add qos_profile_to_bridge_qos() inverse of bridge_qos_to_qos_profile() for converting parsed QosProfile back to BridgeQos when creating federated DDS endpoints. --- crates/ros-z-dds/src/bridge.rs | 384 ++++++++++++++++++++++++++++++--- crates/ros-z-dds/src/pubsub.rs | 44 +++- crates/ros-z-dds/src/qos.rs | 38 +++- 3 files changed, 426 insertions(+), 40 deletions(-) diff --git a/crates/ros-z-dds/src/bridge.rs b/crates/ros-z-dds/src/bridge.rs index 817112b9..fceb8f3c 100644 --- a/crates/ros-z-dds/src/bridge.rs +++ b/crates/ros-z-dds/src/bridge.rs @@ -1,10 +1,18 @@ //!

charset=UTF-8 Content-Transfer-Encoding: 8bit Three failing bridge integration tests (tests 4, 8, 9): - ZDdsServiceBridge req_writer used adapt_writer_qos_for_reader (→ BestEffort) instead of adapt_reader_qos_for_writer (→ Reliable). A BestEffort DDS writer cannot communicate with a ROS 2 service server's Reliable request reader, so the DDS write was silently dropped and the Zenoh query timed out. - ZDdsSubBridge declared its Zenoh subscriber on the exact EMPTY_TOPIC_TYPE/ EMPTY_TOPIC_HASH key derived from the DDS endpoint. When the DDS listener carried a real type hash in user_data the key was specific, so Zenoh publishers using the EMPTY key (test 8) were not routed to the bridge. Fix: subscribe with a wildcard suffix (topic/**) so any publisher on the same ROS topic is forwarded regardless of type/hash. - ZDdsServiceBridge declared its Zenoh queryable on the same specific key, so test 9 (querying EMPTY key) found no complete queryable. Fix: use topic/** wildcard queryable to accept queries from any client type/hash. Also redirect bridge stderr to the log file (was Stdio::null()) so bridge errors are visible when tests fail. --- crates/ros-z-dds/src/bridge.rs | 5 ----- crates/ros-z-dds/src/pubsub.rs | 24 +++++++++++++++--------- crates/ros-z-dds/src/service.rs | 24 +++++++++++++++--------- crates/ros-z-tests/tests/bridge_dds.rs | 3 ++- 4 files changed, 32 insertions(+), 24 deletions(-) diff --git a/crates/ros-z-dds/src/bridge.rs b/crates/ros-z-dds/src/bridge.rs index 4520045f..ba972aa5 100644 --- a/crates/ros-z-dds/src/bridge.rs +++ b/crates/ros-z-dds/src/bridge.rs @@ -452,7 +452,6 @@ impl ZDdsBridge
