New in-process .NET 10 driver project at
src/ZB.MOM.WW.OtOpcUa.Driver.Galaxy/. The Tier-A replacement for
Driver.Galaxy.Host + Driver.Galaxy.Proxy. PR 4.0 ships only the IDriver
shape + factory + options; capability bodies (browse, read, write,
subscribe, deploy-watch, host probes) land in PRs 4.1–4.7.
Files:
- Driver.Galaxy.csproj — net10 x64, AnyCPU+x64 platforms, references
Core.Abstractions + Core. No MxGatewayClient ProjectReference yet — that
comes in PR 4.2 once the gw NuGet package is wired (the user is
shipping mxaccessgw on a parallel track).
- Config/GalaxyDriverOptions.cs — nested record hierarchy
(Gateway/MxAccess/Repository/Reconnect) mirroring the JSON shape spelled
out in lmx_mxgw_impl.md PR 4.0 acceptance section.
- GalaxyDriver.cs — minimal IDriver impl. Initialize/Shutdown toggle
DriverHealth between Healthy/Unknown; Reinitialize bumps the timestamp;
GetMemoryFootprint=0 (PR 4.4 wires SubscriptionRegistry size);
FlushOptionalCachesAsync no-op. Logs intent on lifecycle calls so
partial deployments are diagnosable.
- GalaxyDriverFactoryExtensions.cs — JSON parser, default fill-ins,
validation throw on missing required fields. Driver type name
"GalaxyMxGateway" intentionally distinct from legacy "Galaxy" so both
factories coexist during parity testing (Phase 5). PR 4.W's
Galaxy:Backend switch picks one or the other.
Tests:
- 10 tests in Driver.Galaxy.Tests covering minimal-config defaults, full
override path, three required-field error cases, factory registration
via DriverFactoryRegistry.TryGet, lifecycle health transitions
(Init → Shutdown → Reinit), Dispose idempotency, and post-disposal
ObjectDisposedException.
slnx: registers the new Driver.Galaxy + Driver.Galaxy.Tests projects.
