From 139cb23cb9a39bbdce196637031a175ce1df5ff1 Mon Sep 17 00:00:00 2001 From: William Forney Date: Sun, 26 Jul 2026 07:10:25 -0700 Subject: [PATCH 44/71] Modernize codebase: rename, refactor, enforce .NET style Major refactor replacing legacy C-style class names with modern .NET/C# conventions (e.g., UserToken, Packet, NetworkService). All core networking, packet, and session management classes rewritten using modern C# features, improved encapsulation, and clearer APIs. Method and interface names updated to PascalCase. Buffer, queue, and pool management reimplemented for thread safety and clarity. Message resolver and packet serialization logic refactored. All sample and game server code updated to use new types and APIs. Added .editorconfig for consistent style enforcement. All references to old C* types replaced. Improved access modifiers, collection usage, and synchronization. Codebase now aligns with modern C# best practices for maintainability and readability. --- .editorconfig | 389 +++++++++++++++ CSampleClient/CRemoteServerPeer.cs | 28 +- CSampleClient/Program.cs | 22

This improves maintainability, readability, and aligns with C# best practices. --- .editorconfig | 180 +++++----- favorites.json | 9 + .../server/GameServer.Tests/CHelperTests.cs | 4 +-

Refactored CSampleClient and CSampleServer to use strongly-typed protocol messages and the new PacketProtocol enum. Added movement and user info protocol messages with serialization/deserialization. Removed legacy protocol.cs files. Added Protocol.Tests for protocol stability and message round-trip tests. Updated FreeNet.slnx, improved documentation, and revised connection logic and user handling.

Modernized async I/O by removing SAEA pooling and BufferManager, adopting System.IO.Pipelines for all send/receive logic in UserToken. Updated all usages, tests, and sample code to match the new event and pipelines model. Enabled nullable reference types, cleaned up obsolete code, and updated documentation including a new README section on pipelines. --- CSampleClient/Program.cs | 3 +- CSampleClient/RemoteServerPeer.cs | 2 +- CSampleServer/GameUser.cs | 2 +- CSampleServer/Program.cs | 9 +- Directory.Build.props | 4 +- FreeNet.Tests/CoreInfrastructureTests.cs | 94 +--- FreeNet.Tests/NetworkServiceTests.cs | 72 +-- FreeNet.Tests/PacketTests.cs | 6 +- FreeNet.Tests/ServiceLifecycleTests.cs | 55 +-- FreeNet.Tests/UserTokenTests.cs | 70 ++- FreeNet/BufferManager.cs | 69 --- FreeNet/ConnectedEventArgs.cs | 15 + FreeNet/Connector.cs | 51 +- FreeNet/EventArgs.cs | 24 + FreeNet/FreeNet.csproj | 6 +- FreeNet/HeartbeatSender.cs | 8 +- FreeNet/Listener.cs | 45 +- FreeNet/LogicMessageEntry.cs | 2 +- FreeNet/NetworkService.cs | 276 ++--------- FreeNet/NewClientConnectedEventArgs.cs | 25 + FreeNet/Packet.cs | 45 +- FreeNet/PacketBufferManager.cs | 20 +- FreeNet/ServerUserManager.cs | 6 +- FreeNet/SocketAsyncEventArgsPool.cs | 59 --- FreeNet/UserToken.State.cs | 19 + FreeNet/UserToken.cs | 447 +++++++++--------- README.md | 5 + .../GameRoomPlayStateTests.cs | 1 - .../server/GameServer.Tests/GameRoomTests.cs | 3 - .../ProgramAndServerImplTests.cs | 2 +- viruswar/server/GameServer/GameUser.cs | 10 +- viruswar/server/GameServer/Program.cs | 11 +- 32 files changed, 493 insertions(+), 973 deletions(-) delete mode 100644 FreeNet/BufferManager.cs create mode 100644 FreeNet/ConnectedEventArgs.cs create mode 100644 FreeNet/EventArgs.cs create mode 100644 FreeNet/NewClientConnectedEventArgs.cs delete mode 100644 FreeNet/SocketAsyncEventArgsPool.cs create mode 100644 FreeNet/UserToken.State.cs diff --git a/CSampleClient/Program.cs b/CSampleClient/Program.cs index 1b8da70..5e39ccd 100644 --- a/CSampleClient/Program.cs +++ b/CSampleClient/Program.cs @@ -23,8 +23,9 @@ List gameServers = []; // Register the callback method that will be invoked when the connection succeeds. -connector.ConnectedCallback += serverToken => +connector.Connected += (_, e) => { + var serverToken = e.Token; lock (gameServers) { IPeer server = new RemoteServerPeer(serverToken); diff --git a/CSampleClient/RemoteServerPeer.cs b/CSampleClient/RemoteServerPeer.cs index e1f6b0f..d6fa58d 100644 --- a/CSampleClient/RemoteServerPeer.cs +++ b/CSampleClient/RemoteServerPeer.cs @@ -14,7 +14,7 @@ internal class RemoteServerPeer : IPeer public RemoteServerPeer(UserToken token) { Token = token; - Token.SetPeer(this); + Token.Peer = this; } /// diff --git a/CSampleServer/GameUser.cs b/CSampleServer/GameUser.cs index b9967ad..c8dca74 100644 --- a/CSampleServer/GameUser.cs +++ b/CSampleServer/GameUser.cs @@ -14,7 +14,7 @@ public GameUser(UserToken token, short sig) { _token = token; Sig = sig; - _token.SetPeer(this); + _token.Peer = this; } public short Sig { get; private set; } diff --git a/CSampleServer/Program.cs b/CSampleServer/Program.cs index 95f6005..3d506b4 100644 --- a/CSampleServer/Program.cs +++ b/CSampleServer/Program.cs @@ -7,8 +7,14 @@ NetworkService service = new(false); // Set callback methods. -service.SessionCreatedCallback += token => +service.SessionCreated += (_, e) => { + var token = e.Value; + if (token is null) + { + return; + } + short newid = 0; lock (UserIds) { @@ -32,7 +38,6 @@ }; // Initialize. -service.Initialize(10000, 1024); service.Listen("0.0.0.0", 3369, 100); // Use this to disable heartbeat checks on the server.

Korean text has been removed from C# source files, UI/game messages, protocol enums, and state classes. Documentation files (`README.md`, `TestManual.md`) are now English-only. Added `KOREAN_TEXT_REPORT.md` to summarize the changes. Minor code cleanups include updating `Helper.cs` and replacing the custom `Vector2` struct with `System.Numerics.Vector2`. These changes improve accessibility for English-speaking developers and users. --- KOREAN_TEXT_REPORT.md | 14 ++ README.md | 16 +- TestManual.md | 36 +++-- .../Assets/FreeNet/CFreeNetEventManager.cs | 19 +-- .../Assets/FreeNet/CFreeNetUnityService.cs | 76 +++++----- .../Assets/FreeNet/CRemoteServerPeer.cs | 2 +- .../State/IStateObjectGenerationType.cs | 6 +- .../viruswar/scripts/CNetworkManager.cs | 2 +- .../viruswar/scripts/CPlayerRenderer.cs | 11 +- .../scripts/effect/CScaleController.cs | 2 +- .../viruswar/scripts/play/CBorderViewer.cs | 11 +- .../viruswar/scripts/play/CGameWorld.cs | 8 +- .../Assets/viruswar/scripts/play/CVirus.cs | 20 +-- .../room_state/CBattleRoomGameOverState.cs | 4 +- .../play/room_state/CBattleRoomReadyState.cs | 6 +- .../room_state/CBattleRoomTurnPlayingState.cs | 18 +-- .../play/room_state/CBattleRoomWaitState.cs | 2 +- .../Assets/viruswar/scripts/protocol.cs | 36 ++--- .../viruswar/scripts/public/EasingUtil.cs | 4 +- .../Assets/viruswar/scripts/ui/CBattleRoom.cs | 137 ++++++++---------- .../Assets/viruswar/scripts/ui/CMainMenu.cs | 8 +- .../viruswar/scripts/ui/CPopupResult.cs | 8 +- .../GameServerUtilityTests.cs | 1 + viruswar/server/GameServer/Helper.cs | 4 +- viruswar/server/GameServer/Vector2.cs | 9 -- 25 files changed, 219 insertions(+), 241 deletions(-) create mode 100644 KOREAN_TEXT_REPORT.md delete mode 100644 viruswar/server/GameServer/Vector2.cs diff --git a/KOREAN_TEXT_REPORT.md b/KOREAN_TEXT_REPORT.md new file mode 100644 index 0000000..2933d0a --- /dev/null +++ b/KOREAN_TEXT_REPORT.md @@ -0,0 +1,14 @@ +# KOREAN TEXT EXTRACTION INVENTORY + +## Summary +- Total Korean text entries in C# files: 139 +- Total Korean text lines in README.md: 0 +- Total Korean text lines in TestManual.md: 9 + +## README.md -
