Joseph Doherty b330faff03 mbproxy: cross-platform support — Linux/systemd alongside Windows
Make the service build, run, and install on Linux as a first-class
target while keeping the Windows Service + Event Log behaviour intact.

- Build: drop the hardcoded win-x64 RID — single-file publish now works
  for any RID. publish.ps1 gains -Rid; new publish.sh for Linux hosts.
- Diagnostics: DiagnosticSinkSelector picks the Error+ sink per host —
  Windows Event Log under the SCM, local syslog under systemd
  (Serilog.Sinks.SyslogMessages), none for interactive runs. The
  EventLog truncation helper is extracted so it is testable cross-OS.
- Host: Program.cs registers AddSystemd() alongside AddWindowsService().
- Config: a RID-conditioned appsettings template ships Windows or Unix
  paths; both templates are schema-validated by a test.
- Install: systemd unit (Type=exec) plus install.sh / uninstall.sh.
  Also fixes two cross-platform bugs found while testing: install.ps1
  and uninstall.ps1 used New-EventLog / Remove-EventLog (absent in
  PowerShell 7), and the E2E sim launcher hardcoded Windows venv paths.
- Docs updated across README, CLAUDE.md, and docs/ for dual-platform.

413 tests pass on Windows; 374 (all non-simulator) on Linux.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What this repo is

A personal collection of reference material and tools for working with AVEVA / Wonderware System Platform (formerly Invensys / Wonderware): vendor documentation, sample projects, an active CLI codebase, and a SQL exploration of the Galaxy Repository — pulled together for offline reference and for grounding LLM-assisted work on Wonderware integrations.

How docs are organized

This repo is consumed primarily by LLM coding agents. Documentation follows the rules in DOCS-GUIDE.md — read it before adding or restructuring documentation. The short version:

  • This CLAUDE.md is a thin index: it points to tools, not into them.
  • Each tool has its own README.md at its folder root that introduces the tool and routes into its deep docs.
  • Deep documentation (API references, workflows, incident notes) lives inside each tool folder.

When in doubt about where content belongs, default to pushing it deeper. DOCS-GUIDE.md has the full doctrine and the maintenance rules.

Layout

  • aalogcli/.NET Framework 4.8 / x86 CliFx-based CLI that reads System Platform binary logs (*.aaLGX) for LLM-driven debugging, built on the aaOpenSource/aaLog reader library.
  • aot/ — ArchestrA Object Toolkit 2014 v4.0 reference material (dev guide, API reference, sample VS solutions).
  • graccesscli/.NET Framework 4.8 / x86 CliFx-based CLI for automating Galaxy configuration through the ArchestrA GRAccess COM interop.
  • grdb/ — SQL/DDL exploration of the Galaxy Repository SQL database (queries, schema, hierarchy/tag-name translation).
  • histdb/ — LLM-oriented reference for AVEVA Historian retrieval (extension tables, wwXxx time-domain extensions, retrieval modes/options, alarm-event SQL, REST API). Distilled from the official Historian Retrieval Guide.
  • mbproxy/.NET 10 background service (Windows Service or Linux systemd unit) that proxies Modbus TCP for a fleet of ~54 DL205/DL260 PLCs: inline bidirectional BCD rewriting, single-backend-conn TxId multiplexing (lifts the H2-ECOM100 4-client cap), in-flight read coalescing, and opt-in per-tag response caching.
  • mxaccesscli/.NET Framework 4.8 / x86 CliFx-based CLI for reading, writing, and subscribing to System Platform tags via the MxAccess COM proxy (LMXProxyServerClass).
  • secrets/ — Self-hosted Infisical CLI + secret PowerShell helper for fetching credentials from https://infisical.dohertylan.com instead of inlining plaintext.

Tool / resource index

Task Go to
Read System Platform logs (last N records, last N minutes, ranges, incremental) — for LLM debugging aalogcli/README.md
Anything AOT — object/primitive design, attributes, building, debugging, samples, API reference aot/README.md
Automate Galaxy configuration via GRAccess COM (CLI usage, session daemon, mutations, LLM integration) graccesscli/README.md
Galaxy Repository SQL — connect, schema, hierarchy queries, contained-name ↔ tag-name translation grdb/README.md
AVEVA Historian retrieval — SQL via INSQL, wwXxx extensions, retrieval modes/options, alarm/event SQL, REST API histdb/README.md
Proxy Modbus TCP for DL205/DL260 fleet — BCD rewriting, TxId multiplexing, read coalescing, opt-in response cache, install/ops, status page mbproxy/README.md
Read / write / subscribe to System Platform tags via MxAccess (timeouts, error categories, JSON envelope) mxaccesscli/README.md
Fetch credentials from Infisical instead of using plaintext (secret <KEY> helper, env vars, identity reuse) secrets/README.md

Maintaining this index

Authoritative rules: DOCS-GUIDE.md. The short version that applies here:

  • A new top-level tool requires a new <tool>/README.md first, then one row in the index above pointing to that README. Do not fan out per-file links at the root.
  • A removed tool deletes its row in the same change.
  • When a tool's internals change, update the tool's own README/deep docs — touch this file only if the task → tool mapping changed.
  • If this file grows past ~150 lines or starts repeating tool-internal facts, refactor downward per DOCS-GUIDE.md.
