Client.Go-022 Re-applied Client.Go-015 shape — runWriteBulkVariant drops
the unused secured param and gates -current-user-id /
-verifier-user-id / -user-id behind the secured-only
variants.
Client.Go-023 Re-applied Client.Go-018 shape — bench warm-up and steady-
state loops respect ctx.Err().
Client.Go-024 Added SDK-level tests for WriteBulk / Write2Bulk /
WriteSecuredBulk / WriteSecured2Bulk / ReadBulk and
StreamAlarms via the existing bufconn fake gateway pattern.
Client.Go-025 Five bulk SDK methods short-circuit on empty input without
an RPC round-trip and document the behavior.
Client.Go-026 runBatch widens scanner.Buffer to 16 MiB and emits an
error-with-sentinel if a longer line still arrives, rather
than aborting the session silently.
Client.Go-027 runBatch treats blank lines as skip-and-continue; only EOF
ends the session.
All resolved at 2026-05-24; gofmt + go vet + go build + go test ./... all
green.

Each client's README now covers the alarms surface in both the SDK
section (StreamAlarms / AcknowledgeAlarm beside the existing
QueryActiveAlarms entry, with the streaming-cancellation note) and
the CLI examples (stream-alarms / acknowledge-alarm invocations
mirroring the in-tree implementations across .NET, Go, Rust, Python,
and Java).

Adds the session-less alarm CLI subcommands to mxgw-go. stream-alarms attaches
to the gateway's central alarm feed (--filter-prefix, --limit, --json — NDJSON,
one AlarmFeedMessage per line); acknowledge-alarm is a unary ack (--reference
required, --comment, --operator). StreamAlarms joins QueryActiveAlarms on the
public Client and is wired through the existing batch dispatcher via runWithIO.
SDK type aliases for StreamAlarmsRequest / AlarmFeedMessage / StreamAlarmsClient
land alongside the existing alarm types.

Mirrors the .NET addition: HEAD's session.go had only the subscribe-style
bulks (AddItemBulk / AdviseItemBulk / RemoveItemBulk / UnAdviseItemBulk /
SubscribeBulk / UnsubscribeBulk). This commit ports the value-bulk SDK
surface and CLI subcommands from divergent branch commit f220908.
SDK (clients/go/mxgateway/session.go):
- WriteBulk(ctx, serverHandle int32, entries []*WriteBulkEntry)
- Write2Bulk(ctx, ..., entries []*Write2BulkEntry)
- WriteSecuredBulk(ctx, ..., entries []*WriteSecuredBulkEntry)
- WriteSecured2Bulk(ctx, ..., entries []*WriteSecured2BulkEntry)
- ReadBulk(ctx, serverHandle int32, tagAddresses []string, timeout time.Duration)
→ []*BulkReadResult
types.go gains public re-exports of the generated proto types
(WriteBulkCommand, WriteBulkEntry, Write2BulkCommand, Write2BulkEntry,
WriteSecuredBulkCommand, WriteSecuredBulkEntry, WriteSecured2BulkCommand,
WriteSecured2BulkEntry, ReadBulkCommand, BulkWriteReply, BulkWriteResult,
BulkReadReply, BulkReadResult) so external callers can construct entries
through the public `mxgateway` package without dipping into the internal
generated path.
CLI (clients/go/cmd/mxgw-go/main.go):
- read-bulk, write-bulk, write2-bulk, write-secured-bulk,
write-secured2-bulk routed through runWithIO. write families share a
runWriteBulkVariant helper that gates per-variant flags
(--current-user-id, --verifier-user-id, --timestamp) so the
Client.Go-015 flag-gating contract is preserved.
- bench-read-bulk: percentile + timing helpers; JSON output schema
identical to the .NET / Rust / Python / Java benches.
parseInt32List was changed from panic-on-error to ([]int32, error) so
the new write-bulk commands surface parse errors gracefully; the
existing runUnsubscribeBulk caller is updated accordingly.
Verification: go build ./... + go vet ./... + go test ./... all clean.
Manual smoke against live gateway on localhost:5120: open-session →
register → subscribe-bulk on 3 TestMachine_NNN.TestChangingInt tags
(all wasSuccessful=true) → read-bulk (all wasSuccessful=true /
wasCached=true) → write-bulk int32 100/200/300 (all wasSuccessful=true)
→ close-session SESSION_STATE_CLOSED.

scripts/run-client-e2e-tests.ps1 expects each language CLI to expose a
`batch` subcommand that reads command lines from stdin, runs each
through the normal subcommand dispatch, writes the JSON result, then
a sentinel line `__MXGW_BATCH_EOR__`. The implementation lived on a
divergent branch (commit 6126099) that was never merged into main —
this commit ports the same protocol to HEAD's renamed CLIs so the
existing matrix script runs end-to-end.
The protocol:
- one line of stdin = one full CLI invocation
- successful output → stdout, then __MXGW_BATCH_EOR__
- failure → {"error":"...","type":"error"} JSON on stdout, then
__MXGW_BATCH_EOR__ (errors do NOT exit the loop)
- empty line or EOF terminates the loop
Per-CLI additions:
.NET: RunBatchAsync + per-line StringWriter capture, JSON error
envelope when forceJsonErrors is true. Two new tests in
MxGatewayClientCliTests covering the success and error paths.
Go: runBatch with bufio.Scanner, runs each line through the
existing runWithIO switch with a buffered stdout writer. One new
test pinning the EOR sentinel.
Rust: new `Batch` variant on the clap Command enum, run_batch
re-parses each line via Cli::try_parse_from. Two new tests in the
inline mod tests block.
Python: new `batch` click command in commands.py that uses
CliRunner to dispatch each line; synthesises {"error",..."type"}
JSON from click error messages when the captured output isn't
already JSON-shaped. Three new tests in test_cli.py.
Java: BatchCommand inner @Command with BufferedReader stdin loop,
fresh commandLine() per dispatch with captured stdout/stderr
PrintWriters; non-zero exit codes and uncaught exceptions both
surface as JSON-error blocks. Two new tests.
Also fixes scripts/run-client-e2e-tests.ps1 line 705: the Python
invocation was still passing the old module name `mxgateway_cli` to
`python -m`; the client SDK rename in 397d3c5 moved it to
`zb_mom_ww_mxgateway_cli`. Without the fix the Python leg fails
with "No module named mxgateway_cli" before reaching open-session.
Verification: full matrix at the redeployed gateway (localhost:5120,
running ZB.MOM.WW.MxGateway.Server.exe / ZB.MOM.WW.MxGateway.Worker.exe)
with -SkipBulk -SkipReadWriteBulk -SkipParity -SkipAuth (those phases
exercise bulk read/write CLI subcommands that also live on the
divergent branch — porting those is a follow-up). All five clients
report `closed=true, addedItems=120, eventCount=5` and overall
`success=true`. Per-language unit tests pass:
- dotnet: 59/59
- go: all packages clean
- rust: cargo test --workspace clean
- python: 42/42
- java: gradle build SUCCESSFUL

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.

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.

Pure mechanical regen following PR A.1 (alarm-transition event family
+ AcknowledgeAlarm / QueryActiveAlarms public RPCs). Ran:
- clients/python/generate-proto.ps1 → mxaccess_gateway_pb2.py +
mxaccess_gateway_pb2_grpc.py.
- clients/go/generate-proto.ps1 → mxaccess_gateway.pb.go +
mxaccess_gateway_grpc.pb.go + galaxy_repository.pb.go (whitespace
diff from upstream protoc minor version).
The .NET binding regenerates on csproj rebuild via Grpc.Tools — its
artifact (Generated/MxaccessGateway*.cs) was already updated as part
of A.1's commit. Java + Rust regen happens at build time via the
gradle plugin / build.rs respectively, with no committed output to
update.
Smoke-imported the regenerated Python descriptors:
OnAlarmTransitionEvent.DESCRIPTOR.fields → alarm_full_reference,
alarm_type_name, category, current_value, description, ...
AcknowledgeAlarmRequest.DESCRIPTOR.fields → alarm_full_reference,
client_correlation_id, comment, operator_user, session_id
ActiveAlarmSnapshot.DESCRIPTOR.fields → alarm_full_reference,
alarm_type_name, category, current_state, current_value, ...
PRs E.2 - E.6 layer hand-written SDK methods on top of the regenerated
types — those land per-language as separate PRs.
