Proto comments (comment-only, no wire change):
- mxaccess_worker.proto GatewayHello.max_frame_bytes: every worker->gateway frame
must serialize within the negotiated max; reply builders truncate (IPC-23).
- mxaccess_gateway.proto DrainEventsReply: count-cap + byte-cap, drain-until-empty
caller contract (IPC-23).
- mxaccess_gateway.proto ReplayGap.oldest_available_sequence: empty-ring value is
highest-observed+1, oldest-1 resume formula stays valid (GWC-25 deferred amendment).
Regen wave: Contracts/Generated (C# XML doc), rust vendored protos (byte-copy),
Go bindings (worker binding was genuinely stale - lacked MaxFrameBytes entirely),
Python worker _pb2 (real descriptor delta), Java aggregates (javadoc, zero
protobuf-version churn under the pinned toolchain), client descriptor set.
IPC-24: pinned Java toolchain regenerates with no gencode-version churn, so the
unconditional churn-revert step in ci.yml is a fossil - deleted it; git diff is
now a true message-level drift gate for the single-file Java aggregates.
IPC-25: pin protoc-gen-go v1.36.11 / protoc-gen-go-grpc 1.6.2 in the Go generate
script (+ fix a latent pwsh-7 parse bug); add Check 4 to check-codegen.ps1
(regenerate Go+Python bindings, fail on diff, tool-missing fails not skips); add
the pinned-generator installs to the portable CI job.
IPC-32: relabel check-codegen banners 1/4..4/4 (folded into the Check 4 edit).
Docs: ClientProtoGeneration.md, Contracts.md, GatewayTesting.md, build.gradle
checkGeneratedClean caveat. Tracking: IPC-23/24/25/32 -> Done, GWC-25 proto note
resolved, change-log 2026-08-07.
Rename across every client surface using each language's idiomatic convention:
* .NET clients/dotnet/MxGateway.Client[.Cli|.Tests]/
-> clients/dotnet/ZB.MOM.WW.MxGateway.Client[.Cli|.Tests]/
namespaces -> ZB.MOM.WW.MxGateway.Client[.Cli|.Tests]
contracts ProjectReference repointed to ZB.MOM.WW.MxGateway.Contracts
sln migrated to slnx (dotnet sln migrate)
* Python src/mxgateway -> src/zb_mom_ww_mxgateway
src/mxgateway_cli -> src/zb_mom_ww_mxgateway_cli
distribution: mxaccess-gateway-client -> zb-mom-ww-mxaccess-gateway-client
* Rust crate: mxgateway-client -> zb-mom-ww-mxgateway-client
build.rs proto path repointed
* Java subprojects: mxgateway-{client,cli} -> zb-mom-ww-mxgateway-{client,cli}
packages com.dohertylan.mxgateway -> com.zb.mom.ww.mxgateway
group com.dohertylan.mxgateway -> com.zb.mom.ww.mxgateway
rootProject mxaccessgw-java -> zb-mom-ww-mxaccessgw-java
* Go generate-proto.ps1 proto path repointed; module path and
package mxgateway kept (Go convention).
* proto-inputs.json: generatedOutputs.python updated to new package path.
* scripts/run-client-e2e-tests.ps1: Java CLI install path + gradle task
updated to zb-mom-ww-mxgateway-cli.
CLI binary names (mxgw, mxgw-py, mxgw-go, mxgateway-cli) and wire-level
identifiers (MXGATEWAY_* env vars, the mxgw_<id>_<secret> API key
prefix, protobuf package names like mxaccess_gateway.v1, all MXAccess
references) intentionally NOT renamed.
Fix pre-existing alarms-over-gateway breaks unblocked by the rename:
* mxaccess_gateway.proto: add missing public message QueryActiveAlarmsRequest
{session_id, client_correlation_id, alarm_filter_prefix} and missing
rpc QueryActiveAlarms(QueryActiveAlarmsRequest) returns
(stream ActiveAlarmSnapshot). All four typed clients referenced
these but they were absent from the proto.
* MxAccessGatewayService.QueryActiveAlarms: implement the new RPC on
the server, streaming from IGatewayAlarmService.CurrentAlarms with
optional alarm_filter_prefix filter.
* clients/dotnet/.../DiscoverHierarchyOptions.cs: add the hand-written
.NET POCO that wraps DiscoverHierarchyRequest (referenced by
GalaxyRepositoryClient.DiscoverHierarchyAsync but never authored).
* Drop retired session_id field references from
AcknowledgeAlarmRequest/AcknowledgeAlarmReply test fixtures across
.NET, Rust, Go, and Python clients.
* Rust integration test: add the missing stream_alarms impl on the
fake MxAccessGateway server (the trait gained the method, fake
didn't).
* Rust CLI test: bump expected gatewayProtocolVersion 2 -> 3.
Regenerated artifacts updated in this commit:
* src/ZB.MOM.WW.MxGateway.Contracts/Generated/{MxaccessGateway,MxaccessGatewayGrpc}.cs
* clients/python/src/zb_mom_ww_mxgateway/generated/*_pb2{,_grpc}.py
* clients/go/internal/generated/*.pb.go
(C# regenerated by Grpc.Tools on contracts build; Python and Go via
their generate-proto.ps1 scripts; Rust regenerates from .proto via
tonic-build at compile time so no checked-in artefact.)
Verification: 472 server tests, 275 worker tests (9 dev-rig skipped),
18 integration tests (live MxAccess + LDAP + Galaxy), 57 .NET client
tests, 32 Rust workspace tests, 39 Python tests, all Go packages, and
gradle build for Java all pass.
