From 61fbbb186e3162ba3e27111a26a4837714a0cafb Mon Sep 17 00:00:00 2001 From: Kostas Karachalios Date: Sun, 12 Apr 2026 17:35:26 +0200 Subject: [PATCH 01/31] refactor: scaffold conditional logic for Zenoh transport Prepare the codebase for Zenoh integration without changing behavior. All existing tests pass (1401 passed, 3 xfailed for Phase 2 stubs). - Add `transport` field to GlobalConfig (default: "lcm") - Add ZENOH_AVAILABLE guard in transport.py - Branch _get_transport_for() on global_config.transport - Gate LCM configurators to only run when transport is "lcm" - Add ZenohTransport/pZenohTransport behind ZENOH_AVAILABLE guard - Add zenohpubsub.py stub (raises NotImplementedError) - Add `zenoh` optional dependency group in pyproject.toml - Add test_zenoh_transport.py covering all new conditional branches Co-Authored-By: Claude Opus 4.6 (1M context) --- dimos/core/coordination/module_coordinator.py | 21 ++- dimos/core/global_config.py | 1 + dimos/core/test_zenoh_transport.py | 163 ++++++++++++++++++ dimos/core/transport.py | 92 +++++++++- dimos/protocol/pubsub/impl/zenohpubsub.py | 49 ++++++ pyproject.toml | 5 + uv.lock | 61 ++++++- 7 files changed, 387 insertions(+), 5 deletions(-) create mode 100644 dimos/core/test_zenoh_transport.py create mode 100644 dimos/protocol/pubsub/impl/zenohpubsub.py diff --git a/dimos/core/coordination/module_coordinator.py b/dimos/core/coordination/module_coordinator.py index f6c82a84ff..49ba977e48 100644 --- a/dimos/core/coordination/module_coordinator.py +++ b/dimos/core/coordination/module_coordinator.py @@ -29,7 +29,7 @@ from dimos.core.global_config import GlobalConfig, global_config from dimos.core.module import ModuleBase, ModuleSpec from dimos.core.resource import Resource -from dimos.core.transport import LCMTransport, PubSubTransport, pLCMTransport +from dimos.core.transport import LCMTransport, PubSubTransport, ZENOH_AVAILABLE, pLCMTransport from dimos.spec.utils import spec_annotation_compliance, spec_structural_compliance from dimos.utils.generic import short_id from dimos.utils.logging_config import setup_logger @@ -542,7 +542,21 @@ def _get_transport_for(blueprint: Blueprint, name: str, stream_type: type) -> Pu use_pickled = getattr(stream_type, "lcm_encode", None) is None topic = f"/{name}" if _is_name_unique(blueprint, name) else f"/{short_id()}" - transport = pLCMTransport(topic) if use_pickled else LCMTransport(topic, stream_type) + + if global_config.transport == "zenoh": + if not ZENOH_AVAILABLE: + raise RuntimeError( + "transport='zenoh' but eclipse-zenoh is not installed.

The bridge hardcoded LCM() as its pubsub. Now resolves lazily at start() using self.config.g.transport from the worker's GlobalConfig. 2. Zenoh key expressions cannot contain '#' (forbidden character). Type info is now embedded as a '/' segment in the key expression (e.g., dimos/pointcloud/sensor_msgs.PointCloud2). _key_expr_to_topic reconstructs the Topic with lcm_type for subscribe_all decoding. Also fixes entity path mapping to strip the dimos/ prefix so Zenoh entity paths match LCM paths in the Rerun viewer.
