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.

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.
