# Pull Request: PostgreSQL Integration, Windows Installer, and Documentation Overhaul

## 🎯 Overview

This PR completes the PostgreSQL integration for Jellyfin with comprehensive Windows installer support, centralized build output, OS-specific configuration, and a complete documentation overhaul.

## 🚀 What's New

### 1. **Complete Documentation Overhaul** 📚
- Rewrote **README.md** to highlight PostgreSQL features, Windows installer, and migration guides
- Moved all markdown files to `docs/` folder for better organization (30+ files organized)
- Created comprehensive documentation index with quick start and detailed guides
- Added `README_GENERATION.md` and `DOCUMENTATION_ORGANIZATION.md` for maintenance
- Preserved original README as `README.original.md`
- Clear platform-specific instructions (Windows/Linux/macOS)

### 2. **Professional Windows Installer** 💿
- **Inno Setup script** (`jellyfin-setup.iss`) with full wizard support
- **PowerShell build automation** (`build-installer.ps1`) for easy installer creation
- **Features:**
  - Windows Service installation
  - Firewall rules configuration
  - PostgreSQL connection wizard
  - .NET runtime verification
  - Clean uninstaller
- **Comprehensive documentation:**
  - `INSTALLER_QUICK_START.md` - 5-minute guide
  - `INSTALLER_GUIDE.md` - Complete reference with WiX, MSIX options
  - `BUILD_INSTALLER_FIXED.md` - Build script usage

### 3. **Centralized Build Output** 🔨
- All DLLs now output to `lib\[Configuration]\[TargetFramework]\` at repository root
- Configured via `Directory.Build.props`
- **Benefits:**
  - Single location for all build artifacts
  - Easier deployment and packaging
  - No duplicate dependencies
  - Faster builds
- Documentation: `CENTRALIZED_LIB_FOLDER.md`

### 4. **OS-Specific Startup Configuration** ⚙️
- Auto-generates `startup.json` with OS-appropriate defaults on first run
- **Platform defaults:**
  - **Windows:** `C:/ProgramData/jellyfin`
  - **Linux:** `/var/lib/jellyfin`, `/etc/jellyfin`
  - **macOS:** `~/Library/Application Support/jellyfin`
- Removes null/example config - immediately usable
- Configuration priority: CLI args → Environment vars → startup.json → Built-in defaults
- **Documentation:**
  - `OS_SPECIFIC_STARTUP_CONFIG.md`
  - `STARTUP_JSON_VERIFICATION.md`
  - `STARTUP_JSON_FIX.md`

### 5. **PostgreSQL Migration Improvements** 🗄️
- Assign all tables to correct PostgreSQL schemas in EF Core migrations
- Fix identifier quoting (SQL Server brackets → PostgreSQL double quotes)
- Use InsertData for placeholder BaseItems row (no raw SQL)
- **Auto-recovery:** Handles 42P07 errors (table exists)
- Added `RecordMigrationAsAppliedAsync` for manual migration history
- Improved migration logging and error handling
- **Documentation:**
  - `POSTGRESQL_MIGRATION_COMPLETE.md`
  - `MIGRATION_RECOVERY_FIX.md`
  - `SQLITE_MIGRATION_FILTERING_FIX.md`
- Idempotent, production-ready SQL migration scripts
- PowerShell script for automated migration verification

### 6. **Platform Configuration Templates** 📋
- Added Linux/Windows startup config templates in `Resources/Configuration/`
- FHS-compliant default paths
- Platform-specific README with usage instructions
- Improved portability and cross-platform consistency

### 7. **Build and Deployment Improvements** 🚢
- Enhanced publish profiles with platform targeting
- Clean deploy: deletes existing files before publish
- Updated `.gitignore`:
  - Excludes `lib/` (build output)
  - Excludes `installer-output/`
  - Excludes all `PublishProfiles/` folders (machine-specific)
  - Cleaned up tracked publish profile XMLs
- Switched to relative paths for improved portability

## 🎯 Migration Guide

### From SQLite to PostgreSQL

```bash
# 1. Backup SQLite database
cp jellyfin.db jellyfin-backup.db

# 2. Install PostgreSQL 12+
winget install PostgreSQL.PostgreSQL

# 3. Create database
psql -U postgres
CREATE USER jellyfin WITH PASSWORD 'your_password';
CREATE DATABASE jellyfin OWNER jellyfin;
\q

# 4. Update startup.json
{
  "DatabaseProvider": "Postgres",
  "ConnectionStrings": {
    "DefaultConnection": "Host=localhost;Database=jellyfin;Username=jellyfin;Password=your_password"
  }
}

# 5. Run migration
dotnet run --project Jellyfin.Server -- --migrate-database
```

See `docs/POSTGRESQL_MIGRATION_COMPLETE.md` for details.
