From 0c772d273d0e2bd03237bc2d0f4b293f978be769 Mon Sep 17 00:00:00 2001 From: Joseph Doherty Date: Tue, 5 May 2026 08:06:15 -0400 Subject: [PATCH] =?UTF-8?q?[M3]=20mxaccess-nmx:=20NmxClient=20=E2=80=94=20?= =?UTF-8?q?9=20raw=20INmxService2=20opnums=20(stream=20B)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Lands M3 stream B raw opnum surface: an async NmxClient over the mxaccess-rpc transport that dispatches all 9 INmxService2 procedures (GetPartnerVersion, RegisterEngine2 + WithoutCallback, UnregisterEngine, Connect, AddSubscriberEngine, RemoveSubscriberEngine, SetHeartbeatSendInterval, TransferData) plus a NonZeroHresult error variant that mirrors ThrowIfFailed (cs:563-574). New - crates/mxaccess-nmx/src/client.rs (~580 LoC, 8 tests including 5 real-socket tokio tests against a hand-rolled DCE/RPC server) — port of the raw opnum surface from ManagedNmxService2Client.cs. - NmxClient::connect builds the NTLM-packet-integrity bind path; for tests, NmxClient::from_bound_transport accepts a transport bound any way the caller likes (the test server doesn't validate signatures). - fresh_orpc_this generates a per-call Cid via rand::random(), mirroring the .NET reference's Guid.NewGuid() at every call site. - NmxClientError::NonZeroHresult unifies the .NET reference's Marshal.ThrowExceptionForHR + InvalidOperationException branches so callers see one typed surface for "transport-OK + LMX rejected". Cargo.toml: added tokio, tracing, thiserror, rand to mxaccess-nmx. Two layers of the .NET reference are deliberately out of scope this iteration; both logged as new followups in design/followups.md: - F12 (P1): the auto-resolving Create() factory, which needs windows-rs COM activation (gated by F6) + ComObjRefProvider port. - F13 (P1): the high-level Write*/Advise*/UnAdvise/RegisterReference helpers, which depend on GalaxyTagMetadata from M3 stream A (the Galaxy SQL resolver crate, not yet started). Test count delta: 389 -> 397 (+8). All four DoD gates green.
