name: reset-dev-database description: Reset the development MySQL database by copying the test scenario SQL dump to the Docker init directory, replacing the database name from memoWikisTest to memoWikis_dev, and reinitializing the MySQL container. Use this skill when the user wants to reset, recreate, or reinitialize the development database.

Reset Development Database

This skill automates the process of resetting the development MySQL database using the test scenario SQL dump.

What this skill does

1. Copies the SQL dump file: Takes the test scenario dump from src/Tests/TestData/Dumps/memowikis-test-scenario_tiny.sql and copies it to src/Docker/Dev/mysql-init/schema.sql

2. Replaces the database name: Changes all occurrences of memoWikisTest to memoWikis_dev in the schema file

3. Reinitializes the MySQL container: Stops the Docker containers, removes the MySQL data directory, and restarts the containers

Step-by-step procedure

Step 1: Copy and transform the SQL file

Read the source SQL file and replace the database name:

# Read the SQL dump file
$sqlContent = Get-Content -Path "src/Tests/TestData/Dumps/memowikis-test-scenario_tiny.sql" -Raw

# Replace database name from memoWikisTest to memoWikis_dev
$sqlContent = $sqlContent -replace 'memoWikisTest', 'memoWikis_dev'

# Write to the Docker init directory
$sqlContent | Set-Content -Path "src/Docker/Dev/mysql-init/schema.sql" -Encoding UTF8

Step 2: Reinitialize the MySQL container

Run the following PowerShell commands from the workspace root:

cd ./src/Docker/Dev; `
docker-compose down; `
Remove-Item -Recurse -Force C:\mysql-data\development; `
docker-compose up -d

Important notes

• The MySQL data directory C:\mysql-data\development will be completely deleted
• The MySQL container will automatically execute schema.sql during initialization
• The database name in the SQL file must match the MYSQL_DATABASE value in the .env file (default: memoWikis_dev)

When to use this skill

• When you need to reset the development database to a clean state
• After running the test ScenarioBuilderTests.Deterministic_Tiny_Scenario() to update the schema
• When the database schema has been updated and you need to apply changes
• When the development database is corrupted or in an inconsistent state
