From e8555d780cd9c8126cf51d906075f9c5d6833573 Mon Sep 17 00:00:00 2001 From: Marc Schier Date: Sat, 4 Jul 2026 13:12:57 +0200 Subject: [PATCH 01/12] Add experimental Avro/Protobuf/Arrow reference encoders + PubSub adapters Adds two net8.0+ experimental libraries implementing the draft OPC UA DataEncoding extensions (opcua-drafts) as hand-rolled reference codecs plus PubSub NetworkMessage adapters, with NUnit round-trip tests. Libraries/Opc.Ua.Core.Experimental (IEncoder/IDecoder): - Avro: streaming Avro binary (zig-zag varint, LE floats, nullable unions, NodeId-by-parts); Variant/Action/Discovery support. SchemaId = CRC-64-AVRO Rabin fingerprint + single-object prefix. - Protobuf: hand-rolled protobuf wire; scoped to gRPC service messages. - Arrow: genuinely typed Apache Arrow (Apache.Arrow 18.1.0) - typed arrays, StructArray, ListArray, dense UnionArray; no JSON/blob carrier. Libraries/Opc.Ua.PubSub.Experimental: - Avro adapter drives the real AvroEncoder per field (Avro-in-Avro bytes). - Arrow adapter emits a real columnar RecordBatch (rows = DataSetMessages, typed per-field + header columns) per the Part 14 Arrow batch mapping. Build/scope notes: - net8.0;net9.0;net10.0 only (Apache.Arrow + net5+ BCL); RestrictForLegacyTfm no-ops the legacy CI CustomTestTarget matrix entries. - Round-trip-only conformance for this first reference; unsupported/out-of-scope decode paths fail loud (NotSupportedException), never corrupt. Includes fixes from code review: Avro present-empty-array terminator (fixed + regression test), Arrow dense-union declared type-ids made conformant, Arrow XmlElement decode implemented. Known limitation: Protobuf optional-presence reconstruction is unreliable for structures with 2+ optionals where an earlier one is absent (documented; not exercised by in-scope gRPC messages). ---

Schema exchange (spec alignment): - Add AvroSchemaAnnouncement/Request and ArrowSchemaAnnouncement/Request message types matching the Part 14 §9 / §5.2 descriptors. - Add SchemaCache (thread-safe, announce-once per destination, SchemaId verified on ingest) + ISchemaResolver (pluggable cache-miss resolver), wired into the Avro and Arrow PubSub adapters (encoder announces on first SchemaId use; decoder resolves on miss). A resolver returning bytes inconsistent with the requested SchemaId is treated as "schema not available" so Try* decoders return null rather than throwing. Documented limitation: announcements currently carry an internal shape descriptor (change-tracking proxy), not the canonical Avro PCF / serialized Arrow Schema (cross-implementation interop is a follow-up). New round-trip + handshake tests. Quality hardening (all experimental files): - Add the long-form OPC Foundation MIT copyright header to every file. - Remove all blanket #pragma warning disable and fix the underlying issues (reformat dense one-liners to braced/<=120-col; fix CA and compiler nullable/obsolete warnings). Only 6 narrowly-scoped, justified suppressions remain (5x CA2000 Arrow array ownership handoff, 1x CS0618 raw byte[] body). - Document every public and internal symbol: on IEncoder/IDecoder members (matching JsonEncoder), meaningful summaries elsewhere. Enable GenerateDocumentationFile on both libraries so CS1591 enforces documentation. Builds 0 warnings/0 errors on net8.0/net9.0/net10.0 (docs enforced); Core 21 and PubSub 8 tests pass; legacy-TFM RestrictForLegacyTfm no-op intact.

Behavior, wire encodings, method signatures/semantics and the SchemaId algorithms are unchanged. Copyright headers, XML docs (CS1591 enforced via GenerateDocumentationFile) and the 6 narrowly-scoped justified pragmas are preserved.

In Batch mode the encoder emits a bare Arrow RecordBatch message without the embedded Schema message (a fixed ~1.2 KB per message), exposing the schema-message bytes/length so the schema can be announced once out of band and resolved by SchemaId (the Arrow Flight model). The decoder caches schemaId->schema (from a full stream or CacheSchema) and reconstructs schema+batch+EOS to decode bare batches, reusing the existing decode path. Adds bare-batch round-trip tests and an IPC framing-breakdown measurement (schema vs batch bytes, stream vs bare-batch size per sample). --- .../Encoding/Arrow/ArrowIpcFraming.cs | 52 +++++++++ .../Arrow/ArrowNetworkMessageDecoder.cs | 86 +++++++++++++++ .../Arrow/ArrowNetworkMessageEncoder.cs | 38 ++++++- .../Arrow/ArrowPubSubRoundTripTests.cs | 103 ++++++++++++++++++ .../Part14PubSubEncoderComparisonTests.cs | 46 ++++++++ 5 files changed, 324 insertions(+), 1 deletion(-) create mode 100644 Libraries/Opc.Ua.PubSub.Experimental/Encoding/Arrow/ArrowIpcFraming.cs diff --git a/Libraries/Opc.Ua.PubSub.Experimental/Encoding/Arrow/ArrowIpcFraming.cs b/Libraries/Opc.Ua.PubSub.Experimental/Encoding/Arrow/ArrowIpcFraming.cs new file mode 100644 index 0000000000..532f144051 --- /dev/null +++ b/Libraries/Opc.Ua.PubSub.Experimental/Encoding/Arrow/ArrowIpcFraming.cs @@ -0,0 +1,52 @@ +/* ======================================================================== + * Copyright (c) 2005-2025 The OPC Foundation, Inc.

ArrowNetworkMessageEncoder.Framing now defaults to ArrowIpcFraming.Batch; tests that need a self-contained stream set Framing=Stream explicitly.
