Dedicated Server Software - Minecraft.Server.exe (#498)

* add: Dedicated Server implementation

- Introduced `ServerMain.cpp` for the dedicated server logic, handling command-line arguments, server initialization, and network management.
- Created `postbuild_server.ps1` script for post-build tasks, including copying necessary resources and DLLs for the dedicated server.
- Added `CopyServerAssets.cmake` to manage the copying of server assets during the build process, ensuring required files are available for the dedicated server.
- Defined project filters in `Minecraft.Server.vcxproj.filters` for better organization of server-related files.

* add: refactor world loader & add server properties

- Introduced ServerLogger for logging startup steps and world I/O operations.
- Implemented ServerProperties for loading and saving server configuration from `server.properties`.
- Added WorldManager to handle world loading and creation based on server properties.
- Updated ServerMain to integrate server properties loading and world management.
- Enhanced project files to include new source and header files for the server components.

* update: implement enhanced logging functionality with configurable log levels

* update: update keyboard and mouse input initialization 1dc8a005ed111463c22c17b487e5ec8a3e2d30f3

* fix: change virtual screen resolution to 1920x1080(HD)

Since 31881af56936aeef38ff322b975fd0 , `skinHud.swf` for 720 is not included in `MediaWindows64.arc`,
the app crashes unless the virtual screen is set to HD.

* fix: dedicated server build settings for miniaudio migration and missing sources

- remove stale Windows64 Miles (mss64) link/copy references from server build
- add Common/Filesystem/Filesystem.cpp to Minecraft.Server.vcxproj
- add Windows64/PostProcesser.cpp to Minecraft.Server.vcxproj
- fix unresolved externals (PostProcesser::*, FileExists) in dedicated server build

* update: changed the virtual screen to 720p

Since the crash caused by the 720p `skinHud.swf` not being included in `MediaWindows64.arc` has been resolved, switching back to 720p to reduce resource usage.

* add: add Docker support for Dedicated Server

add with entrypoint and build scripts

* fix: add initial save for newly created worlds in dedicated server

on the server side, I fixed the behavior introduced after commit aadb511, where newly created worlds are intentionally not saved to disk immediately.

* update: add basically all configuration options that are implemented in the classes to `server.properties`

* update: add LAN advertising configuration for server.properties

LAN-Discovery, which isn’t needed in server mode and could potentially be a security risk, has also been disabled(only server mode).

* add: add implementing interactive command line using linenoise

- Integrated linenoise library for line editing and completion in the server console.
- Updated ServerLogger to handle external writes safely during logging.
- Modified ServerMain to initialize and manage the ServerCli for command input.
- The implementation is separate from everything else, so it doesn't affect anything else.
- The command input section and execution section are separated into threads.

* update: enhance command line completion with predictive hints

Like most command line tools, it highlights predictions in gray.

* add: implement `StringUtils` for string manipulation and refactor usages

Unified the scattered utility functions.

* fix: send DisconnectPacket on shutdown and fix Win64 recv-thread teardown race

Before this change, server/host shutdown closed sockets directly in
ServerConnection::stop(), which bypassed the normal disconnect flow.
As a result, clients could be dropped without receiving a proper
DisconnectPacket during stop/kill/world-close paths.

Also, WinsockNetLayer::Shutdown() could destroy synchronization objects
while host-side recv threads were still exiting, causing a crash in
RecvThreadProc (access violation on world close in host mode).

* fix: return client to menus when Win64 host connection drops

- Add client-side host disconnect handling in CPlatformNetworkManagerStub::DoWork() for _WINDOWS64.
- When in QNET_STATE_GAME_PLAY as a non-host and WinsockNetLayer::IsConnected() becomes false, trigger g_NetworkManager.HandleDisconnect(false) to enter the normal disconnect/UI flow.
- Use m_bLeaveGameOnTick as a one-shot guard to prevent repeated disconnect handling while the link remains down.
- Reset m_bLeaveGameOnTick on LeaveGame(), HostGame(), and JoinGame() to avoid stale state across sessions.

* update: converted Japanese comments to English

* add: create `Minecraft.Server` developer guide in English and Japanese

* update: add note about issue

* add: add `nlohmann/json` json lib

* add: add FileUtils

Moved file operations to `utils`.

* add: Dedicated Server BAN access manager with persistent player and IP bans

- add Access frontend that publishes thread-safe ban manager snapshots for dedicated server use
- add BanManager storage for banned-players.json and banned-ips.json with load/save/update flows
- add persistent player and IP ban checks during dedicated server connection handling
- add UTF-8 BOM-safe JSON parsing and shared file helpers backed by nlohmann/json
- add Unicode-safe ban file read/write and safer atomic replacement behavior on Windows
- add active-ban snapshot APIs and expiry-aware filtering for expires metadata
- add RAII-based dedicated access shutdown handling during server startup and teardown

* update: changed file read/write operations to use `FileUtils`.

- As a side effect, saving has become faster!

* fix: Re-added the source that had somehow disappeared.

* add: significantly improved the dedicated server logging system

- add ServerLogManager to Minecraft.Server as the single entry point for dedicated-server log output
- forward CMinecraftApp logger output to the server logger when running with g_Win64DedicatedServer
- add named network logs for incoming, accepted, rejected, and disconnected connections
- cache connection metadata by smallId so player name and remote IP remain available for disconnect logs
- keep Minecraft.Client changes minimal by using lightweight hook points and handling log orchestration on the server side

* fix: added the updated library source

* add: add `ban` and `pardon` commands for Player and IP

* fix: fix stop command shutdown process

add dedicated server shutdown request handling

* fix: fixed the save logic during server shutdown

Removed redundant repeated saves and eliminated the risks of async writes.

* update: added new sever files to Docker entrypoint

* fix: replace shutdown flag with atomic variable for thread safety

* update: update Dedicated Server developer guide

English is machine translated.
Please forgive me.

* update: check for the existence of `GameHDD` and create

* add: add Whitelist to Dedicated Server

* refactor: clean up and refactor the code

- unify duplicated implementations that were copied repeatedly
- update outdated patterns to more modern ones

* fix: include UI header (new update fix)

* fix: fix the detection range for excessive logging

`getHighestNonEmptyY()` returning `-1` occurs normally when the chunk is entirely air.
The caller (`Minecraft.World/LevelChunk.cpp:2400`) normalizes `-1` to `0`.

* update: add world size config to dedicated server properties

* update: update README add explanation of  `server.properties` & launch arguments

* update: add nightly release workflow for dedicated server and client builds to Actions

* fix: update name for workflow

* add random seed generation

* add: add Docker nightly workflow for Dedicated Server publish to GitHub Container Registry

* fix: ghost player when clients disconnect out of order

#4

* fix: fix 7zip option

* fix: fix Docker workflow for Dedicated Server artifact handling

* add: add no build Dedicated Server startup scripts and Docker Compose

* update: add README for Docker Dedicated Server setup with no local build

* refactor: refactor command path structure

As the number of commands has increased and become harder to navigate, each command has been organized into separate folders.

* update: support stream(file stdin) input mode for server CLI

Support for the stream (file stdin) required when attaching a tty to a Docker container on Linux.

* add: add new CLI Console Commands for Dedicated Server

Most of these commands are executed using the command dispatcher implemented on the `Minecraft.World` side. When registering them with the dispatcher, the sender uses a permission-enabled configuration that treats the CLI as a player.

- default game.
- enchant
- experience.
- give
- kill(currently, getting a permission error for some reason)
- time
- weather.
- update tp & gamemode command

* fix: change player map icon to random select

* update: increase the player limit

* add: restore the basic anti-cheat implementation and add spawn protection

Added the following anti-cheat measures and add spawn protection to `server.properties`.
- instant break
- speed
- reach

* fix: fix Docker image tag

+## Dedicated Server in Docker (Wine)
+
+This repository includes a lightweight Docker setup for running the Windows dedicated server under Wine.
+### Quick Start (No Build, Recommended)
+
+No local build is required. The container image is pulled from GHCR.
+
+```bash
+./start-dedicated-server.sh
+```
+
+`start-dedicated-server.sh` does the following:
+- uses `docker-compose.dedicated-server.ghcr.yml`
+- pulls latest image, then starts the container
+
+If you want to skip pulling and just start:
+
+```bash
+./start-dedicated-server.sh --no-pull
+```
+
+Equivalent manual command:
+
+```bash
+docker compose -f docker-compose.dedicated-server.ghcr.yml up -d
+```
+
+### Local Build Mode (Optional)
+
+Use this only when you want to run your own locally built `Minecraft.Server` binary in Docker.
+**A local build of `Minecraft.Server` is required for this mode.**
+
+```bash
+docker compose -f docker-compose.dedicated-server.yml up -d --build
+```
+
+Useful environment variables:
+- `XVFB_DISPLAY` (default: `:99`)
+- `XVFB_SCREEN` (default: `64x64x16`, tiny virtual display used by Wine)
+
+Fixed server runtime behavior in container:
+- executable path: `/srv/mc/Minecraft.Server.exe`
+- bind IP: `0.0.0.0`
+- server port: `25565`
+
+Persistent files are bind-mounted to host:
+- `./server-data/server.properties` -> `/srv/mc/server.properties`
+- `./server-data/GameHDD` -> `/srv/mc/Windows64/GameHDD`
+
+### About `server.properties`
+
+`Minecraft.Server` reads `server.properties` from the executable working directory (Docker image: `/srv/mc/server.properties`).
+If the file is missing or contains invalid values, defaults are auto-generated/normalized on startup.
+
+Important keys:
+
+| Key | Values / Range | Default | Notes |
+|-----|-----------------|---------|-------|
+| `server-port` | `1-65535` | `25565` | Listen TCP port |
+| `server-ip` | string | `0.0.0.0` | Bind address |
+| `server-name` | string (max 16 chars) | `DedicatedServer` | Host display name |
+| `max-players` | `1-8` | `8` | Public player slots |
+| `level-name` | string | `world` | Display world name |
+| `level-id` | safe ID string | derived from `level-name` | Save folder ID; normalized automatically |
+| `level-seed` | int64 or empty | empty | Empty = random seed |
+| `world-size` | `classic\|small\|medium\|large` | `classic` | World size preset for new worlds and expansion target for existing worlds |
+| `log-level` | `debug\|info\|warn\|error` | `info` | Server log verbosity |
+| `autosave-interval` | `5-3600` | `60` | Seconds between autosaves |
+| `white-list` | `true/false` | `false` | Enable access list checks |
+| `lan-advertise` | `true/false` | `false` | LAN session advertisement |
+
+Minimal example:
+
+```properties
+server-name=DedicatedServer
+server-port=25565
+max-players=8
+level-name=world
+level-seed=
+world-size=classic
+log-level=info
+white-list=false
+lan-advertise=false
+autosave-interval=60
+```
+
+### Dedicated Server launch arguments
+
+The server loads base settings from `server.properties`, then CLI arguments override those values.
+
+| Argument | Description |
+|----------|-------------|
+| `-port <1-65535>` | Override `server-port` |
+| `-ip <addr>` | Override `server-ip` |
+| `-bind <addr>` | Alias of `-ip` |
+| `-name <name>` | Override `server-name` (max 16 chars) |
+| `-maxplayers <1-8>` | Override `max-players` |
+| `-seed <int64>` | Override `level-seed` |
+| `-loglevel <level>` | Override `log-level` (`debug`, `info`, `warn`, `error`) |
+| `-help` / `--help` / `-h` | Print usage and exit |
+
+Examples:
+
+```powershell
+Minecraft.Server.exe -name MyServer -port 25565 -ip 0.0.0.0 -maxplayers 8 -loglevel info
+Minecraft.Server.exe -seed 123456789
+```
