.NET/Go/Python/Rust clients (plus Contracts, which releases in lockstep
with the .NET Client) move 0.2.0 -> 0.2.1; Java moves 0.2.1 -> 0.2.2. This
starts the next release train the finding recommended, since post-publish
source changes (including the Python connect() event-loop fix, a8f86b5)
had been sitting at already-published version numbers for nine days with
nothing recording the divergence.
- Note the pypi 0.2.0 connect() defect and its supersession by 0.2.1 in
clients/python/README.md and docs/ClientPackaging.md.
- Add scripts/check-client-versions.ps1: a PR-time guard that finds each
client's latest publish tag (clients/go/vX.Y.Z for Go, the only client
with a git tag; the other four publish straight to a registry with no
tag, so the check reports "no tags found" and passes for them) and fails
if clients/<lang> changed since that tag while the version constant
still equals the tag's version. Wired into .gitea/workflows/ci.yml's
portable job next to the codegen freshness checks (needs fetch-depth: 0
for tag history).
- Mark remediation batch A Done in
archreview/2026-08-19/remediation/00-tracking.md.
Verified on macOS: dotnet build clients/dotnet/...slnx (pass), cargo check
--workspace (pass), python -m pytest (168 passed, 1 skipped), gradle test
with JDK 17 (pass, no generated-tree churn to revert this time), gofmt -l
+ go build ./... + go test ./... (clean), and
scripts/check-client-versions.ps1 via pwsh (pass; also verified it fails
correctly when a version constant is rolled back).
Converges all five clients on one version after four had drifted onto the
already-published 0.1.2/0.1.1 while their APIs kept changing underneath it:
- Rust Cargo.toml [package] + [workspace.package] -> 0.2.0 (CLIENT_VERSION
already derives from CARGO_PKG_VERSION, no separate edit).
- Python pyproject.toml + version.py -> 0.2.0; new test asserts __version__
matches pyproject.toml (closes the CLI-26 residual drift mode).
- Go mxgateway/version.go ClientVersion -> 0.2.0.
- .NET ZB.MOM.WW.MxGateway.Client.csproj <Version> -> 0.2.0.
- Java -> 0.2.1, not 0.2.0: the live Gitea Maven feed already had 0.2.0
published (2026-06-26), before the CLI-37/38/40/41 conformance fixes
changed the client's observable behavior, so reusing 0.2.0 would label
two different APIs identically. Recorded as an exception in
docs/ClientPackaging.md's new Versioning section.
Publish-pipeline guards:
- scripts/tag-go-module.ps1 implements the CLI-21 guard: after semver
validation it refuses to tag unless clients/go/mxgateway/version.go's
ClientVersion already matches the requested tag version.
- scripts/pack-clients.ps1 gains a Gitea package-registry collision guard
wired into every per-language -Publish step; it aborts if the target
name+version already exists rather than force-overwriting. Verified live
against the real Gitea registry (credentials already present in this
environment) — correctly refuses on every known-published artifact and
passes on every unpublished target.
Docs updated in the same commit: docs/ClientPackaging.md (new Versioning
section), and the five client READMEs' stale 0.1.1/0.1.2 example versions.
No .proto changes. No publish performed.
Ninth PR of the alarms-over-gateway epic
(docs/plans/alarms-over-gateway.md). Mirrors PR E.2's .NET surface
on the Go SDK. Depends on PR E.1 (regen, merged).
- Client.AcknowledgeAlarm — context-aware unary call routed through
the existing callContext helper (default 30s timeout). Failures
wrap into *GatewayError; protocol-status non-OK promotes to typed
protocol errors via EnsureProtocolSuccess.
- Client.QueryActiveAlarms — context-streaming wrapper around the
generated MxAccessGateway_QueryActiveAlarmsClient. Caller drives
the stream via Recv(); cancelling ctx releases it.
- types.go re-exports the four new generated types
(AcknowledgeAlarmRequest/Reply, QueryActiveAlarmsRequest,
ActiveAlarmSnapshot) plus the AlarmTransitionKind /
AlarmConditionState enums and the
QueryActiveAlarmsClient stream alias.
- version.go bumps GatewayProtocolVersion 1 → 3 to match the .NET
contract; the const was previously stale and the bump fixes the
pre-existing TestOpenSessionFixtureProtocolVersions failure that
was masked because the fixture had not been regenerated until A.1.
Tests:
- 4 new tests in alarms_test.go — request shape + auth metadata,
nil-request rejection, Unauthenticated mapping, snapshot
streaming over bufconn, filter-prefix passthrough.
- All Go test suites green: cmd/mxgw-go + mxgateway.
