v1.0.7
c6b515b

Date: 2026-07-30
Previous release: v1.0.6

Summary

Dial now propagates DialOptions.Logger into the underlying MMS client when
MMS.Logger is unset (matching existing Server behaviour). Dependency bump to
go-mms v1.0.6 / go-cotp v1.0.3. Docs and Makefile tooling aligned with sibling
OT Fabric libraries, including a real make fuzz target. Broad unit-test
coverage lift (non-example packages ~90–100%). Go floor remains 1.24.

Fixed

  • Dial logger → MMS — when DialOptions.Logger is set and
    DialOptions.MMS.Logger is nil, the IEC logger is passed through to
    iso.Dial / mms.Client (Server already did this).

Dependencies

  • go-mms — v1.0.5 → v1.0.6
  • go-cotp (indirect) — v1.0.2 → v1.0.3

Changed

  • OBSERVABILITY.md / options godoc / doc.go — clarify IEC→MMS logger
    inheritance and that iso.WithLogger is independent.
  • API.md — document IEDName on DialOptions/ClientOptions; note logger
    propagation.

Build / tooling

  • Makefile — exports GOWORK=off; make fuzz runs the eight root fuzz
    targets plus FuzzParse in ./scl (replaces the stale “planned for M6”
    stub).

Tests

Coverage pass across client, server, SCL, and internal/servermodel
(approximate statement coverage: root ~90%, scl ~92%,
scl/validate 100%, scl/index ~93%, scl/internal/genir ~93%,
internal/servermodel ~87%). Notable additions:

  • Values / Write / client helpers — type-mismatch and nil guards on
    accessors; Write validation edges; ldDomain / refToMMS /
    stripIEDPrefix.
  • Server — installWriteInterceptor (RCB / SGCB / CO / DA notify),
    parseCOStoreKey / parseRCBStoreKey.
  • Control / reports — Operate / Select / SelectWithValue / Cancel /
    ReadCtlModel / ReadLastApplError edges; buildCancel; OrCat /
    AddCause String; ListReportsVerified / verifyReportCandidates.
  • Setting groups (client) — GetSettingGroupInfo, SelectActiveSG /
    SelectEditSG / ConfirmEditSG, GetEditSGValue / SetEditSGValue /
    GetActiveSGValue, decodeSGCB member-type edges; server
    GetEditSettingGroup.
  • Data sets — List / Get / Read / Create / Delete validation and
    loopback paths; memberIdentity; lazy-cache ReadDataSet.
  • SCL — Parse / ParseFile / ParseFileOpts / ParseWithOptions /
    ParseBytes (strict, MaxDiagnostics, read failures); DetectKind /
    KindFromPath; flatten GSE/SMV/ConnectedAP exports; index
    FindGSEControl / FindSMVControl; validate package edge matrix;
    v1.7 convert Private / SMV / SettingControl / LogControl; genir
    Emit / enums / types / SCL root / type-resolve helpers; sclparse
    list-smv / completion / version string.
  • servermodel — registerSGCB, compound registerDA /
    registerDAWithFC, RCB register Read/Write via MMS loopback,
    makeStructRead / buildAttrElemAndRead.

No public API surface changes. No breaking changes.

Import path remains github.com/otfabric/go-iec61850.
