Joseph Doherty 7740a3bcf9 feat: add JoeAppEngine OPC UA nodes, fix DCL auto-reconnect and quality push
- Add JoeAppEngine folder to OPC UA nodes.json (BTCS, AlarmCntsBySeverity, Scheduler/ScanTime)
- Fix DataConnectionActor: capture Self in PreStart for use from non-actor threads,
  preventing Self.Tell failure in Disconnected event handler
- Implement InstanceActor.HandleConnectionQualityChanged to mark attributes Bad on disconnect
- Fix LmxFakeProxy TagMapper to serialize arrays as JSON instead of "System.Int32[]"
- Allow DataType and DataSourceReference updates in TemplateService.UpdateAttributeAsync
- Update test_infra_opcua.md with JoeAppEngine documentation

ScadaLink Test Infrastructure

Local Docker-based test services for ScadaLink development.

Quick Start

docker compose up -d

This starts five services:

Service Port Purpose
OPC UA (Azure IoT OPC PLC) 50000 (OPC UA), 8080 (web) Simulated OPC UA server with ScadaLink-style tags
LDAP (GLAuth) 3893 Lightweight LDAP with test users/groups matching ScadaLink roles
MS SQL 2022 1433 Configuration and machine data databases
SMTP (Mailpit) 1025 (SMTP), 8025 (web) Email capture for notification testing
REST API (Flask) 5200 External REST API for Gateway and Inbound API testing
LmxFakeProxy (.NET gRPC) 50051 (gRPC) LmxProxy-compatible server bridging to OPC UA test server

First-Time SQL Setup

The MS SQL container does not auto-run init scripts. After the first docker compose up -d, run:

docker exec -i scadalink-mssql /opt/mssql-tools18/bin/sqlcmd \
  -S localhost -U sa -P 'ScadaLink_Dev1#' -C \
  -i /docker-entrypoint-initdb.d/setup.sql

This creates the ScadaLinkConfig and ScadaLinkMachineData databases and the scadalink_app login. Then seed the Machine Data database:

docker exec -i scadalink-mssql /opt/mssql-tools18/bin/sqlcmd \
  -S localhost -U sa -P 'ScadaLink_Dev1#' -C \
  -i /docker-entrypoint-initdb.d/machinedata_seed.sql

Stopping & Teardown

Stop containers (data persists in SQL volume):

docker compose down

Stop a single service (leave the others running):

docker compose stop opcua      # or: ldap, mssql, smtp, restapi
docker compose start opcua     # bring it back without recreating

Full teardown (stop containers, delete SQL data volume, remove pulled images):

./teardown.sh

Or manually:

docker compose down -v         # stop containers + delete SQL data volume
docker compose down -v --rmi all  # also remove downloaded images

After a full teardown, the next docker compose up -d starts fresh — you'll need to re-run the SQL setup script.

CLI Tools

Python CLI tools for interacting with the test services are in tools/.

Set up a Python virtual environment (one-time):

python3 -m venv tools/.venv && source tools/.venv/bin/activate

Install dependencies (one-time, with venv active):

pip install -r tools/requirements.txt

The .venv directory is gitignored.

Quick readiness check (all five services, with venv active):

python tools/opcua_tool.py check
python tools/ldap_tool.py check
python tools/mssql_tool.py check
python tools/smtp_tool.py check
python tools/restapi_tool.py check
Tool Service Key Commands
tools/opcua_tool.py OPC UA check, browse, read, write, monitor
tools/ldap_tool.py LDAP check, bind, search, users, groups
tools/mssql_tool.py MS SQL check, setup, query, tables
tools/smtp_tool.py SMTP (Mailpit) check, send, list, read, clear
tools/restapi_tool.py REST API (Flask) check, call, methods

Each tool supports --help for full usage. See the per-service docs below for detailed examples.
