 ## Troubleshooting Connection Issues
 ### Error: `57P01: terminating connection due to administrator command`
 **Cause**: PostgreSQL server forcibly terminated the connection during an operation
 **Common reasons**:
 - PostgreSQL server restart or reload
 - Connection timeout (statement_timeout, idle_in_transaction_session_timeout)
 - Manual connection termination via `pg_terminate_backend()`
 - Network instability or firewall issues
 - Resource limits exceeded (max_connections, memory pressure)
 **Solutions**:
 #### 1. Configure Automatic Retry (Already Enabled)
 Jellyfin now includes automatic retry logic for transient failures:
 - **Max retries**: 3 attempts
 - **Max delay**: 5 seconds between retries
 - **Retryable errors**: Includes `57P01` (connection termination)
 #### 2. Increase PostgreSQL Timeouts
 Edit PostgreSQL configuration (`/etc/postgresql/*/main/postgresql.conf`):
 ```
 # Increase statement timeout
 statement_timeout = 300000              # 5 minutes (in milliseconds)
 # Increase idle transaction timeout
 idle_in_transaction_session_timeout = 600000  # 10 minutes
 # Enable TCP keepalives (prevent network timeouts)
 tcp_keepalives_idle = 60                # seconds
 tcp_keepalives_interval = 10            # seconds
 tcp_keepalives_count = 6
 ```
 Reload PostgreSQL:
 ```bash
 sudo systemctl reload postgresql
 # OR
 psql -U postgres -c "SELECT pg_reload_conf();"
 ```
 #### 3. Optimize Connection String
 Add keepalive and timeout parameters to your connection string:
 ```xml
 <ConnectionString>Host=192.168.129.253;Port=5432;Database=jellyfin;Username=jellyfin;Password=yourpass;Pooling=True;Minimum Pool Size=0;Maximum Pool Size=50;Connection Idle Lifetime=300;Connection Pruning Interval=10;Timeout=30;Command Timeout=300;Keepalive=60</ConnectionString>
 ```
 **Key parameters**:
 - `Timeout=30` - Connection establishment timeout (30 seconds)
 - `Command Timeout=300` - Query execution timeout (5 minutes)
 - `Keepalive=60` - TCP keepalive interval (60 seconds)
 - `Connection Idle Lifetime=300` - Close idle connections after 5 minutes
 - `Connection Pruning Interval=10` - Check for stale connections every 10 seconds
 #### 4. Check PostgreSQL Logs
 On your PostgreSQL server:
 ```bash
 # View recent logs
 sudo tail -f /var/log/postgresql/postgresql-*.log
 # Or check systemd journal
 sudo journalctl -u postgresql -n 100 --no-pager
 ```
 Look for:
 - `received fast shutdown request`
 - `terminating connection`
 - `too many connections`
 - `out of memory`
 #### 5. Monitor Active Connections
 ```sql
 -- Check current connections
 SELECT 
    datname, 
    usename, 
    application_name,
    state,
    state_change
 FROM pg_stat_activity
 WHERE datname = 'jellyfin'
 ORDER BY state_change DESC;
 -- Check connection limits
 SELECT 
    (SELECT setting::int FROM pg_settings WHERE name = 'max_connections') AS max_connections,
    (SELECT COUNT(*) FROM pg_stat_activity) AS current_connections,
    (SELECT COUNT(*) FROM pg_stat_activity WHERE datname = 'jellyfin') AS jellyfin_connections;
 ```

 # WebSocket Authentication Guide
 ## Overview
 WebSocket connections to Jellyfin servers require authentication. This guide explains how to properly authenticate WebSocket connections using API tokens.
 ## Authentication Methods
 ### 1. Query String Parameter (Recommended for WebSocket)
 The simplest and most compatible method for WebSocket connections.
 **URL Format:**
 ```
 ws://jellyfin-server:8096/socket?api_key=YOUR_API_TOKEN
 wss://jellyfin-server:8096/socket?api_key=YOUR_API_TOKEN  (for HTTPS)
 ```
 **JavaScript Example:**
 ```javascript
 const token = "YOUR_API_KEY";
 const ws = new WebSocket(`ws://jellyfin-server:8096/socket?api_key=${token}`);
 ws.onopen = function(event) {
 	console.log("WebSocket connection established with authentication");
 };
 ws.onerror = function(event) {
 	console.error("WebSocket error:", event);
 };
 ws.onmessage = function(event) {
 	const message = JSON.parse(event.data);
 	console.log("Received message:", message);
 };
 ws.onclose = function(event) {
 	console.log("WebSocket connection closed");
 };
 ```
 **Python Example:**
 ```python
 import asyncio
 import websockets
 import json
 async def connect_with_token():
 	token = "YOUR_API_KEY"
 	uri = f"ws://jellyfin-server:8096/socket?api_key={token}"
 	async with websockets.connect(uri) as websocket:
 		print("Connected to Jellyfin WebSocket")
 		# Receive messages
 		async for message in websocket:
 			data = json.loads(message)
 			print(f"Received: {data}")
 asyncio.run(connect_with_token())
 ```
 **C# Example:**
 ```csharp
 using System;
 using System.Net.WebSockets;
 using System.Threading;
 using System.Threading.Tasks;
 public class JellyfinWebSocketClient
 {
 	public async Task ConnectAsync(string serverUrl, string token)
 	{
 		var uri = new Uri($"ws://{serverUrl}:8096/socket?api_key={token}");
 		using (var client = new ClientWebSocket())
 		{
 			await client.ConnectAsync(uri, CancellationToken.None);
 			Console.WriteLine("Connected to Jellyfin WebSocket");
 			// Receive messages
 			var buffer = new byte[1024 * 4];
 			while (client.State == WebSocketState.Open)
 			{
 				var result = await client.ReceiveAsync(
 					new ArraySegment<byte>(buffer),
 					CancellationToken.None);
 				if (result.MessageType == WebSocketMessageType.Text)
 				{
 					var message = System.Text.Encoding.UTF8.GetString(
 						buffer, 0, result.Count);
 					Console.WriteLine($"Received: {message}");
 				}
 			}
 		}
 	}
 }
 ```
 ### 2. Authorization Header (Alternative)
 For advanced use cases, you can also use the Authorization header.
 **Header Format:**
 ```
 Authorization: MediaBrowser Device="ClientName", DeviceId="unique-id", Version="1.0", Token="YOUR_API_TOKEN"
 ```
 **Note:** Some WebSocket implementations may not support custom headers during the upgrade handshake. Query parameters are recommended.
 ## Obtaining an API Token
 ### Via Server UI
 1. Navigate to your Jellyfin server dashboard
 2. Go to Settings → API Keys (or similar, depending on version)
 3. Create a new API key
 4. Copy the token to use in your WebSocket connection
 ### Programmatically
 Use the REST API to create API keys:
 ```bash
 curl -X POST "http://jellyfin-server:8096/Auth/Keys" \
  -H "Authorization: MediaBrowser Token=existing_token" \
  -H "Content-Type: application/json" \
  -d '{"AppName": "My WebSocket Client"}'
 ```
 ## Common Issues
 ### Connection Refused / 401 Unauthorized
 - Verify the API token is correct
 - Ensure the token hasn't expired
 - Check that the WebSocket endpoint path is correct (`/socket`)
 ### Token Not Found
 - Verify the query parameter is URL-encoded properly
 - Ensure the parameter name is correct: `api_key` (lowercase)
 - Check server logs for authentication errors
 ### WebSocket Connection Fails Immediately
 - Confirm the server is reachable
 - Check firewall rules allow WebSocket connections
 - Try with `wss://` (secure WebSocket) if using HTTPS
 ## Server Configuration
 The server automatically extracts tokens from:
 1. Authorization header (MediaBrowser Token parameter)
 2. Query string `api_key` parameter
 3. Query string `ApiKey` parameter
 4. Legacy headers (if enabled in config)
 No special server configuration is required for WebSocket authentication to work.
 ## Security Considerations
 - Always use `wss://` (secure WebSocket) when connecting over untrusted networks
 - Keep API tokens secure and rotate them periodically
 - Use separate tokens for different clients/applications
 - Consider implementing token expiration in your server configuration

 # Library Options DB Design
 This document turns the earlier storage discussion into concrete PostgreSQL DDL and C# repository sketches that fit the patterns already used in this repository.
 Relevant existing patterns:
 - PostgreSQL migrations use `MigrationBuilder.Sql(...)` in provider-specific migrations under `src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres/Migrations/`.
 - EF entities live under `src/Jellyfin.Database/Jellyfin.Database.Implementations/Entities/`.
 - `DbSet<>` registrations live in `src/Jellyfin.Database/Jellyfin.Database.Implementations/JellyfinDbContext.cs`.
 - PostgreSQL table mapping lives in `src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres/PostgresDatabaseProvider.cs`.
 - Runtime repositories typically use `IDbContextFactory<JellyfinDbContext>` and `await using var context = _dbProvider.CreateDbContext();` as seen in `Jellyfin.Server.Implementations/Item/MediaStreamRepository.cs`.
 - Virtual path storage is already handled by `IServerApplicationHost.ReverseVirtualPath(...)` and `ExpandVirtualPath(...)`.
 ## Option 1: Minimal-Change JSON-In-DB
 ### Goal
 Persist one `LibraryOptions` document per collection folder in PostgreSQL with minimal change to the existing `CollectionFolder.GetLibraryOptions(...)` and `SaveLibraryOptions(...)` flow.
 ### Table Design
 ```sql
 CREATE TABLE library."LibraryOptions" (
    "LibraryId" uuid NOT NULL,
    "LibraryPath" text NOT NULL,
    "OptionsJson" jsonb NOT NULL,
    "Version" integer NOT NULL DEFAULT 1,
    "DateCreated" timestamp with time zone NOT NULL DEFAULT now(),
    "DateModified" timestamp with time zone NOT NULL DEFAULT now(),
    CONSTRAINT "PK_LibraryOptions" PRIMARY KEY ("LibraryId")
 );
 CREATE UNIQUE INDEX "IX_LibraryOptions_LibraryPath"
    ON library."LibraryOptions" USING btree ("LibraryPath");
 CREATE INDEX "IX_LibraryOptions_DateModified"
    ON library."LibraryOptions" USING btree ("DateModified" DESC);
 ```
 ### Suggested PostgreSQL Migration

        }
        /// <inheritdoc />
        protected override void Down(MigrationBuilder migrationBuilder)
        {
            migrationBuilder.Sql(@"DROP TABLE IF EXISTS library.""LibraryOptions"" CASCADE;");
        }
    }
 }
 ```
 ### Suggested Entity
 ```csharp
 // <copyright file="LibraryOptionsEntity.cs" company="PlaceholderCompany">
 // Copyright (c) PlaceholderCompany. All rights reserved.
 // </copyright>
 namespace Jellyfin.Database.Implementations.Entities;
 using System;
 public class LibraryOptionsEntity
 {
    public Guid LibraryId { get; set; }
    public required string LibraryPath { get; set; }
    public required string OptionsJson { get; set; }
    public int Version { get; set; }
    public DateTime DateCreated { get; set; }
    public DateTime DateModified { get; set; }
 }
 ```
 ### DbContext / Provider Mapping
 Add to `JellyfinDbContext`:
 ```csharp
 public DbSet<LibraryOptionsEntity> LibraryOptions => this.Set<LibraryOptionsEntity>();
 ```
 Add to `PostgresDatabaseProvider.ConfigureEntities(...)`:
 ```csharp
 modelBuilder.Entity<LibraryOptionsEntity>().ToTable("LibraryOptions", Schemas.Library);
 ```
 Recommended extra configuration:
 ```csharp
 modelBuilder.Entity<LibraryOptionsEntity>()
    .HasIndex(e => e.LibraryPath)
    .IsUnique();
 ```

            await context.SaveChangesAsync(cancellationToken).ConfigureAwait(false);
        }).ConfigureAwait(false);
    }
 }
 ```
 ### CollectionFolder Integration Sketch
 The minimal integration strategy is:
 1. Change `CollectionFolder.LoadLibraryOptions(...)` to try the repository first.
 2. If no database row exists, fall back to `options.xml`.
 3. After a successful XML read, persist the value into `library."LibraryOptions"`.
 4. Keep the current static cache keyed by library path.
 Pseudo-flow:
 ```csharp
 var fromDb = await _libraryOptionsRepository.GetLibraryOptionsAsync(libraryId, path, cancellationToken);
 if (fromDb is not null)
 {
    return fromDb;
 }
 var fromXml = LoadLibraryOptionsFromXml(path);
 await _libraryOptionsRepository.SaveLibraryOptionsAsync(libraryId, path, fromXml, cancellationToken);
 return fromXml;
 ```
 ### Tradeoffs
 - Lowest risk.
 - No relational visibility into individual media roots.
 - Best fit if the goal is only to stop using `options.xml` as the persistence backend.
 ## Option 2: Hybrid JSON + Queryable Media Paths
 ### Goal
 Keep the full `LibraryOptions` object as JSON for compatibility, but project `PathInfos` into a separate relational table so path-level reporting and joins are cheap and reliable.
 ### Table Design
 ```sql
 CREATE TABLE library."LibraryOptions" (
    "LibraryId" uuid NOT NULL,
    "LibraryPath" text NOT NULL,
    "OptionsJson" jsonb NOT NULL,
    "Version" integer NOT NULL DEFAULT 1,
    "DateCreated" timestamp with time zone NOT NULL DEFAULT now(),
    "DateModified" timestamp with time zone NOT NULL DEFAULT now(),
    CONSTRAINT "PK_LibraryOptions" PRIMARY KEY ("LibraryId")
 );
 CREATE UNIQUE INDEX "IX_LibraryOptions_LibraryPath"
    ON library."LibraryOptions" USING btree ("LibraryPath");
 CREATE TABLE library."LibraryMediaPaths" (
    "Id" uuid NOT NULL,
    "LibraryId" uuid NOT NULL,
    "Path" text NOT NULL,
    "PathVirtual" text NOT NULL,
    "Position" integer NOT NULL,
    "DateCreated" timestamp with time zone NOT NULL DEFAULT now(),
    "DateModified" timestamp with time zone NOT NULL DEFAULT now(),
    CONSTRAINT "PK_LibraryMediaPaths" PRIMARY KEY ("Id"),
    CONSTRAINT "FK_LibraryMediaPaths_LibraryOptions_LibraryId"
        FOREIGN KEY ("LibraryId") REFERENCES library."LibraryOptions" ("LibraryId") ON DELETE CASCADE
 );
 CREATE UNIQUE INDEX "IX_LibraryMediaPaths_LibraryId_Position"
    ON library."LibraryMediaPaths" USING btree ("LibraryId", "Position");
 CREATE INDEX "IX_LibraryMediaPaths_Path"
    ON library."LibraryMediaPaths" USING btree ("Path");
 CREATE INDEX "IX_LibraryMediaPaths_PathVirtual"
    ON library."LibraryMediaPaths" USING btree ("PathVirtual");
 CREATE INDEX "IX_LibraryMediaPaths_LibraryId"
    ON library."LibraryMediaPaths" USING btree ("LibraryId");

 ### Operational Queries Enabled By The Hybrid Model
 ```sql
 SELECT lmp."LibraryId", lmp."Path", lmp."PathVirtual"
 FROM library."LibraryMediaPaths" AS lmp
 WHERE lmp."Path" = '/media/main_bridge/media/movies'
   OR lmp."PathVirtual" = '/media/main_bridge/media/movies';
 ```
 ```sql
 SELECT lmp."Path", count(*) AS "LibraryCount"
 FROM library."LibraryMediaPaths" AS lmp
 GROUP BY lmp."Path"
 HAVING count(*) > 1
 ORDER BY "LibraryCount" DESC, lmp."Path";
 ```
 ### Tradeoffs
 - Slightly more implementation work than the JSON-only option.
 - Keeps the current `LibraryOptions` object model intact.
 - Makes media roots queryable, indexable, and auditable.
 - Requires a transactional write path so JSON and projected rows do not drift.
 ## Recommended Touch Points In This Repo
 Regardless of which option is chosen, the same set of integration points will need to move:
 - `MediaBrowser.Controller/Entities/CollectionFolder.cs`
  - Replace raw XML read/write with repository-backed read/write.
  - Keep XML fallback for a transition period if rollback safety matters.
 - `src/Jellyfin.Database/Jellyfin.Database.Implementations/JellyfinDbContext.cs`
  - Add `DbSet<>` properties.
 - `src/Jellyfin.Database/Jellyfin.Database.Implementations/Entities/`
  - Add `LibraryOptionsEntity` and, for the hybrid approach, `LibraryMediaPathEntity`.
 - `src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres/PostgresDatabaseProvider.cs`
  - Add table mapping and relationship/index configuration.
 - `src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres/Migrations/`
  - Add provider-specific migration(s).
 - `Jellyfin.Server.Implementations/Library/`
  - Add a repository class and register it in DI.
 ## Recommended Rollout
 ### JSON-In-DB
 1. Add the table, entity, mapping, and repository.
 2. Read DB first, then fall back to XML.
 3. Backfill on demand when XML is encountered.
 4. Keep XML writes optional for one release if rollback support is needed.
 ### Hybrid
 1. Add both tables, entities, mapping, and repository.
 2. Save JSON and `PathInfos` projection in one transaction.
 3. Read DB first, then fall back to XML.
 4. Add a small admin or diagnostic query surface over `LibraryMediaPaths`.
 5. Remove XML writes after migration confidence is high.
 ## Recommendation
 If the immediate goal is only to stop relying on `options.xml`, choose the JSON-only design.
 If the goal includes operational visibility into library roots, duplicate path detection, path remapping support, or future query-driven tooling, choose the hybrid design. The hybrid design is the better long-term fit for PostgreSQL while still preserving the current `LibraryOptions` object graph and call sites.

 # Database Configuration Migration Guide
 ## Overview
 Jellyfin has transitioned from XML-based (`database.xml`) to JSON-based (`database.json`) configuration for database settings. This provides better support for interface types, cleaner syntax, and improved maintainability.
 ## Backward Compatibility
 **The system is fully backward compatible.** If you have an existing `database.xml` file, Jellyfin will continue to work without any changes needed. The configuration loader automatically:
 1. Checks for `database.json` first
 2. Falls back to `database.xml` if JSON doesn't exist
 3. Creates default configuration files as needed
 ## Migration Options
 ### Option 1: Automatic Migration (Recommended)
 Simply rename or create a new `database.json` file in your Jellyfin configuration directory. The old `database.xml` will continue to work as a fallback.
 ### Option 2: Manual Migration
 If you want to migrate from `database.xml` to `database.json`:
 1. **Backup your existing configuration:**
   ```bash
   cp /path/to/config/database.xml /path/to/config/database.xml.backup
   ```
 2. **Create a new `database.json`:**
   Use the provided `database.json.example` as a template and copy it to `database.json`:
   ```bash
   cp database.json.example /path/to/config/database.json
   ```
 3. **Edit `database.json`** with your specific settings:
   - Update the `connectionString` with your database credentials
   - Adjust `backupOptions` if using PostgreSQL
   - Keep any custom provider settings
 4. **Test the new configuration:**
   Start Jellyfin and verify it connects successfully to your database in the logs.
 5. **Remove the old file (optional):**
   Once confirmed working, you can remove `database.xml`:
   ```bash
   rm /path/to/config/database.xml
   ```
 ## Format Differences
 ### XML Format (Legacy)
 ```xml
 <?xml version="1.0" encoding="utf-8"?>
 <DatabaseConfigurationOptions>
  <DatabaseType>Jellyfin-PostgreSQL</DatabaseType>
  <LockingBehavior>NoLock</LockingBehavior>
  <CustomProviderOptions>
 	<PluginName>Jellyfin-PostgreSQL</PluginName>
 	...
  </CustomProviderOptions>
 </DatabaseConfigurationOptions>
 ```
 ### JSON Format (Current)
 ```json
 {
  "databaseType": "Jellyfin-PostgreSQL",
  "lockingBehavior": "NoLock",
  "customProviderOptions": {
 	"pluginName": "Jellyfin-PostgreSQL",
 	...
  }
 }
 ```
 ## Configuration File Location
 The configuration file should be placed in your Jellyfin configuration directory:
 - **Linux:** `/etc/jellyfin/` or `~/.config/jellyfin/`
 - **Windows:** `%APPDATA%\jellyfin\`
 - **Docker:** `/config/` (mounted volume)
 ## Key Differences
 | Feature | XML | JSON |
 |---------|-----|------|
 | Supports interfaces | ❌ | ✅ |
 | Human-readable | ✅ | ✅ |
 | Backward compatible | ✅ | ✅ (via fallback) |
 | Easier parsing | ❌ | ✅ |
 ## Troubleshooting
 ### Error: "Error loading configuration file"
 - Ensure the JSON file is valid JSON (use a JSON validator)
 - Check file permissions (must be readable by Jellyfin process)
 - Verify the configuration path is correct
 ### Fallback to XML
 If you see logs indicating XML deserialization, this means:
 - No `database.json` file was found
 - The system is using the existing `database.xml` as fallback
 - This is normal and expected during migration
 ### Performance Note
 JSON parsing is faster than XML, so you may see slight improvements after migration.
 ## Support
 For issues related to database configuration:
 1. Check that your JSON syntax is valid
 2. Verify database connection settings
 3. Review Jellyfin logs for detailed error messages
 4. Keep a backup of your working configuration
