# MariaDB production bootstrap

## What this app supports
- SQLite for local/dev fallback
- MariaDB/MySQL for production when configured with:
  - `DATABASE_PROVIDER=mariadb`
  - `JOBTRACKER_CONNECTION_STRING=...`

## 1. Create database and user in MariaDB
Run this against your MariaDB server/container:

```sql
CREATE DATABASE jobtracker CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
CREATE USER 'jobtracker'@'%' IDENTIFIED BY 'REPLACE_WITH_STRONG_PASSWORD';
GRANT ALL PRIVILEGES ON jobtracker.* TO 'jobtracker'@'%';
FLUSH PRIVILEGES;
```

## 2. Configure server `.env`
Example:

```env
DATABASE_PROVIDER=mariadb
JOBTRACKER_CONNECTION_STRING=server=mariadb;port=3306;database=jobtracker;user=jobtracker;password=REPLACE_WITH_STRONG_PASSWORD
AUTH_JWT_KEY=replace_with_long_random_secret
AUTH_ADMIN_EMAIL=you@example.com
AUTH_ADMIN_PASSWORD=replace_with_strong_password
APP_PUBLIC_BASE_URL=https://your-domain.example
SUMMARIZER_BASE_URL=http://summarizer:8001
```

## 3. First startup
On first deploy, the API will run EF migrations at startup.
That means the MariaDB schema is created automatically as long as:
- the DB exists
- credentials are correct
- the backend container can reach `mariadb`

## 4. SQLite to MariaDB migration notes
This repo now includes helper tooling to make migration safer:
- `deploy/sqlite_export.py` exports the important SQLite tables into JSON
- `deploy/sqlite_preview.py` lets you inspect the exported payload quickly

Suggested migration path:

1. Stop writes to the app
2. Back up SQLite DB file
3. Export SQLite data:
   - `python deploy/sqlite_export.py /path/to/jobtracker.db sqlite-export.json`
4. Preview the export:
   - `python deploy/sqlite_preview.py sqlite-export.json`
5. Start MariaDB-backed environment on a staging copy
6. Import with a one-time script/manual loader tailored to your production data
7. Validate users, companies, jobs, correspondence, attachments metadata
8. Switch production `.env` to MariaDB

## Tables you would likely want to migrate
- `AspNetUsers`
- `AspNetRoles`
- `AspNetUserRoles`
- `Companies`
- `JobApplications`
- `Correspondences`
- `Attachments`
- `JobEvents`
- `GmailConnections`
- `UserRuleSettings`

## Important note on attachments
Files are stored separately from DB rows.
When moving environments, make sure you preserve:
- `/data`
- especially attachments and data-protection keys

## Suggested validation checklist after switching
- can log in with admin user
- profile loads
- jobs list loads
- correspondence loads
- attachments metadata still matches files on disk
- summarizer works
- reminders page works
- admin/system page loads
