Fix the MxSparseArray type-defaults table in gateway.md to use the real MxDataType
enum member names (Integer, not Integer/LongInteger; Time, not Time/Timestamp) and
clarify the int64 note. Add a docstring sentence to write_array_elements in the
Python client noting that indices and total_length must be non-negative.
Regenerate Python proto bindings to pick up MxSparseArray/MxSparseElement/
sparse_array_value from the shared mxaccess_gateway.proto. Add
Session.write_array_elements which builds an MxValue(sparse_array_value=…)
from a {index→scalar} dict and delegates to the existing write(). Add 8 pytest
tests covering builder correctness and full round-trip wire shape. Update
README with a default-fill semantics paragraph and bare-name array-write note.
A consuming project hit two MXAccess parity surprises: a plain Write only
records its user_id when the item has an active supervisory advise (the path
to take when not authenticating), and array writes replace the whole array
rather than patching individual elements. Document both across the five client
READMEs and gateway.md's compatibility baseline, and expose the missing
advise-supervisory subcommand in the go/python/rust/java CLIs (plus the .NET
help text) so callers can establish the supervisory advise without dropping to
the raw command API.
Server-054/055/056, Contracts-020/021/022, Tests-036/038/039,
IntegrationTests-030/031/032 (+033 deferred to live rig),

Key fix: SessionEventDistributor orphaned a subscriber that registered after
the pump completed but before disposal (Server-056) -> register paths now
complete late registrants under _lifecycleLock; regression test added. The
racy dashboard-mirror gRPC test made deterministic (Tests-039).
Verified green locally: gateway Tests targeted classes (GatewaySession,
SessionEventDistributor, GatewayOptionsValidator, ProtobufContractRoundTrip,
GatewaySessionDashboardMirror) + dotnet/go/python/rust client suites.
Add --parent-gobject-id (integer) to the galaxy-browse CLI command so the
Python client matches the Go (-parent) and Rust (--parent-gobject-id) CLIs.
When set, drives BrowseChildren paging via browse_children_raw (page size 500,
repeated-token guard) and renders the same JSON node shape (flattened object
fields + hasChildrenHint + empty children array) and indented-text tree as the
root-walk path. --depth is ignored on the parent path with a one-line stderr
warning, matching the Go/Rust behaviour. Tests added in TDD order.
Guard _galaxy_browse against unbounded recursion by rejecting --depth
values outside [0, 50] with a descriptive BadParameter. Add test coverage
for --depth 99 and --depth -1 rejection, and assert _text is never
present in the JSON output from galaxy-browse.
Add a "High-level walker" subsection under each client's "Browsing
lazily" section showing idiomatic use of LazyBrowseNode (browse +
expand, idempotency note, redeploy refresh pattern).
Client.Python-022 README CLI examples for stream-alarms and
acknowledge-alarm now use the correct flags;
regression test parses every documented line through
Click.
Client.Python-023 Re-applied Client.Python-013 — _use_plaintext drops
the silent localhost / 127.0.0.1 auto-downgrade
branch; --plaintext and --tls are mutually exclusive
and TLS is the default.
Client.Python-024 batch dispatch routes through main.main(...,
standalone_mode=False) under a redirected stdout
instead of click.testing.CliRunner; recursive batch
lines are rejected outright.
Client.Python-025 Added behavioural tests for the five bulk SDK methods,
stream_alarms, and the new CLI subcommands.
Client.Python-026 _bench_read_bulk hoists 'import time' to module scope
and logs cleanup failures instead of swallowing them.
All resolved at 2026-05-24; python -m pytest is 65/65 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-py. stream-alarms reads a
bounded slice of the gateway's central alarm feed (--filter-prefix,
--max-messages, --timeout, --json; aggregate `{messages: [...]}`);
acknowledge-alarm is a unary ack (--reference required, --comment, --operator).
GatewayClient.stream_alarms joins query_active_alarms via a
_canceling_alarm_feed_iterator helper mirroring the existing
_canceling_active_alarms_iterator pattern.

Mirrors the .NET / Go ports of divergent branch commit f220908. HEAD's
Session class had only the subscribe-style bulks; this commit adds the
value-bulk SDK surface plus matching CLI subcommands and a
bench-read-bulk harness.
SDK (zb_mom_ww_mxgateway/session.py):
- async def write_bulk(server_handle, entries, *, correlation_id="")
→ list[pb.BulkWriteResult]
- async def write2_bulk(server_handle, entries, *, correlation_id="")
→ list[pb.BulkWriteResult]
- async def write_secured_bulk(server_handle, entries, *, correlation_id="")
→ list[pb.BulkWriteResult]
- async def write_secured2_bulk(server_handle, entries, *, correlation_id="")
→ list[pb.BulkWriteResult]
- async def read_bulk(server_handle, tag_addresses, *, timeout_ms=0,
correlation_id="") → list[pb.BulkReadResult]
All five reuse the existing _ensure_bulk_size validator and route
through the existing invoke() pipeline. read_bulk additionally enforces
timeout_ms >= 0.
CLI (zb_mom_ww_mxgateway_cli/commands.py):
- read-bulk / write-bulk / write2-bulk / write-secured-bulk /
write-secured2-bulk registered as click @main.command(...). The
write families share a _build_write_bulk_entries() helper that parses
--item-handles and --values with a single --type, validates count
match, converts via to_mx_value, and assembles the correct per-entry
proto message.
- bench-read-bulk: opens its own session, subscribes to --bulk-size
TestMachine_NNN.TestChangingInt tags, runs warmup then steady-state
ReadBulk for --duration-seconds with time.perf_counter() latency
capture, and emits the shared JSON schema (language, durationMs,
totalCalls, successfulCalls, failedCalls, totalReadResults,
cachedReadResults, callsPerSecond, latencyMs:{p50,p95,p99,max,mean})
so scripts/bench-read-bulk.ps1 collates Python alongside the four
other clients. _percentile_summary + linear-interpolation
_percentile helper match the Go / .NET implementations.
to_mx_value is added to the existing values-module import line in
commands.py since the bulk-write commands need it.
Verification: python -m pip install -e . --quiet --no-deps; pytest
42/42 passing. Manual smoke against live gateway on localhost:5120:
open-session → register → subscribe-bulk on two
TestMachine_NNN.TestChangingInt tags (both wasSuccessful=true) →
read-bulk (both wasSuccessful=true / wasCached=true / int32 values
present) → 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.

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.
