From c727d79f05bbd7b585f75f71dcb1190db04e3da3 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 4 May 2026 20:18:23 +0000 Subject: [PATCH 01/10] Retire GameServer; clean up Cluster/World/Realm project layering Removes the merged "all-in-one" GameServer executable. The distributed WorldCluster + WorldServer pair is now the only supported topology. - Delete src/server/GameServer/ project and its Dockerfile. - Drop GameServer entries from Mangos.sln and dev/docker-compose.yml; update dev/README.md startup steps. - Mangos.World.csproj: remove WorldServer; the standalone WorldServer/ exe owns that role. - RealmServer.csproj: drop unused Mangos.Cluster project reference; no source under RealmServer/ uses cluster code, so this was a stray layering violation. - No source-level circular dependencies between Mangos.Cluster and Mangos.World remain; both share only Mangos.Cluster.Interop. First step toward the world-cluster proxy redesign. https://claude.ai/code/session_016a7UDPm1QxBbGTNt5weY4F --- dev/GameServer.Dockerfile | 12 - dev/README.md | 3 +- dev/docker-compose.yml | 24 +- src/server/GameServer/GameModule.cs | 43 -

The C# call surface (ICluster / IWorld) is unchanged so all existing call sites in Mangos.World keep compiling; only the underlying wire format and dispatcher organization change. Three explicit buckets, mirrored across InteropMethodId, ICluster, IWorld, and both dispatchers/proxies: 1. Relay (0x0200-0x020F): per-client lifecycle plus the WoW packet hot path. Cluster decrypts inbound and forwards as one-way envelopes; PacketOut flows back the same way. 2.

clean exit codes PR #3 in the world-cluster-proxy series. The cluster gains a process supervisor; worlds gain documented exit codes and a real autonomous mode. What landed: * ExitCodes (Mangos.Cluster.Interop/ExitCodes.cs): 0 clean, 2 config, 3 db-version, 10 restart-requested, 11 stop-requested, 20 fatal, 30 orphaned. Used by both processes; the supervisor reads them to decide respawn behaviour. * SupervisorConfiguration (Mangos.Configuration): per-world entries with Mode = Internal | External so cluster either forks the process itself (Internal) or just tracks state (External, for systemd / docker / k8s). Heartbeat interval, stale/dead thresholds, and exponential respawn backoff are all configurable. Disabled by default so existing single-process setups are unchanged. * WorldSupervisor + SupervisedWorld (Mangos.Cluster/Supervision/): reconcile loop spawns Idle worlds, heartbeats the live ones via IWorld.Ping/GetServerInfo, marks Stale/Dead on missed beats, drains-then-kills on stop/restart. Cross-platform: System.Diagnostics .Process for both Linux and Windows; Process.Kill(entireProcessTree) for hard kills. PickLeastLoaded(mapId) does load-aware placement using the new ServerInfo fields - this is what will back .instance spawn in PR #5. * ServerInfo extended with PlayerCount, InstanceCount, BattlegroundCount, UptimeMs. WS_Network.WorldServerClass.GetServerInfo now populates them so heartbeats carry real load data day one. * Cluster wiring: WorldServerClass.Connect now calls supervisor .OnWorldHello(uri, world, maps); Disconnect calls OnWorldGoodbye(uri). WorldCluster/Program.cs starts the supervisor before the IPC server and registers ProcessExit / Ctrl-C handlers. * WorldServer/Program.cs now has a 60s grace window when the cluster is unreachable, after which it exits Orphaned (30) so the supervisor can respawn it on cluster recovery. Console Ctrl-C exits Clean (0); fatal startup failures exit FatalCrash (20). No source-level cycles; Mangos.Cluster -> Mangos.Configuration only, Mangos.Configuration -> Mangos.Common only. Worlds and clusters can each survive without the other and supervise each other on restart. https://claude.ai/code/session_016a7UDPm1QxBbGTNt5weY4F --- dev/configuration.json | 9 + .../Mangos.Cluster.Interop/ExitCodes.cs | 50 +++ .../Protocol/InteropSerializer.cs | 10 +- .../Mangos.Cluster.Interop/ServerInfo.cs | 32 ++ .../Mangos.Cluster/LegacyClusterModule.cs | 10 + .../Network/WorldServerClass.cs | 8 +- .../Supervision/SupervisedWorld.cs | 86 ++++ .../Supervision/WorldSupervisor.cs | 419 ++++++++++++++++++ .../MangosConfiguration.cs | 6 + .../SupervisorConfiguration.cs | 89 ++++ .../Mangos.Configuration/configuration.json | 9 + .../Network/WS_Network.WorldServerClass.cs | 12 +- src/server/WorldCluster/Program.cs | 19 + src/server/WorldServer/Program.cs | 54 ++- 14 files changed, 798 insertions(+), 15 deletions(-) create mode 100644 src/server/Mangos.Cluster.Interop/ExitCodes.cs create mode 100644 src/server/Mangos.Cluster/Supervision/SupervisedWorld.cs create mode 100644 src/server/Mangos.Cluster/Supervision/WorldSupervisor.cs create mode 100644 src/server/Mangos.Configuration/SupervisorConfiguration.cs diff --git a/dev/configuration.json b/dev/configuration.json index 247575cd..15817bb0 100644 --- a/dev/configuration.json +++ b/dev/configuration.json @@ -12,6 +12,15 @@ "CharacterDatabase": "root;rootpass;mysql;3306;mangosVBcharacters;MySQL", "WorldDatabase": "root;rootpass;mysql;3306;mangosVBworld;MySQL" }, + "Supervisor": { + "Enabled": false, + "HeartbeatIntervalMs": 5000, + "StaleAfterMissed": 3, + "DeadAfterMissed": 5, + "RespawnBackoffStepMs": 2000, + "RespawnBackoffMaxMs": 60000, + "Worlds": [] + }, "World": { "ClusterConnectHost": "127.0.0.1", "ClusterConnectPort": 50001, diff --git a/src/server/Mangos.Cluster.Interop/ExitCodes.cs b/src/server/Mangos.Cluster.Interop/ExitCodes.cs new file mode 100644 index 00000000..c0034dfe --- /dev/null +++ b/src/server/Mangos.Cluster.Interop/ExitCodes.cs @@ -0,0 +1,50 @@ +// +// Copyright (C) 2013-2025 getMaNGOS +// +// This program is free software.

Introduces the federation bus that PRs #5 and #6 will reuse for in-game GM commands and cross-realm chat/groups respectively. Highlights: * New project Mangos.Cluster.Admin holds the shared protocol so the in-game chat handler, the cluster console, and (future) external CLI all speak the same wire format. Lives at the same layer as Mangos.Cluster.Interop; both are referenced by Mangos.Cluster. * Federation transport: FederationLink wraps an InteropConnection but uses its own 0x0300+ method-id range (PeerHello/Ack, Heartbeat, AdminCommand). FederationServer accepts inbound dials, verifies a HMAC-SHA256 PeerHello using a per-peer shared secret from config, and tracks authenticated links keyed by remote cluster id. * Admin command schema: AdminCommand carries verb + TargetRealmId/WorldId/InstanceId/MapId/GraceSeconds/Extras. AdminCommandReply is status + lines. Same struct used by all three entry points (in-game chat, cluster console, external CLI). AdminCommandParser handles the unified ".server / .instance / .realm" syntax including --realm cross-cluster routing flags. * ClusterAdminCommandHandler implements IAdminCommandHandler against the supervisor: server list/info/start/stop/restart, instance list, realm list. The remaining verbs (instance spawn/restart/etc.) hook in once PR #5 wires the in-game side that calls them. * ConsoleAdminRepl runs in the background on cluster startup, reading stdin and dispatching through the same handler used by the federation transport. * SQL migration sql/Updates/Accounts/Rel21_02_002.sql adds the realmlist columns (clusterId, clusterAdminEndpoint, displayTag, markerPosition), the per-account federation_show_markers toggle, and the federation_group / federation_group_member tables for PR #6's cross-realm group state. Uses ADD COLUMN IF NOT EXISTS so it's idempotent. Bumps db_version to (21,2,2); MangosGlobalConstants.RevisionDbRealmContent goes 1 -> 2. * FederationConfiguration with Enabled/LocalClusterId/LocalDisplayTag/ ListenAddress/ListenPort/MarkerMode/Peers wired into MangosConfiguration. Sample blocks added to dev/configuration.json, dev/configuration.distributed.json, and the in-tree sample. All ship Enabled=false so existing single-cluster setups are unchanged. Federation peers are authenticated by symmetric HMAC over (clusterId || nonce); rotate the secret to evict. Listener and admin transport share the framed-TCP InteropConnection format - one transport everywhere, separate listener port (default 50101 vs the world IPC's 50001). https://claude.ai/code/session_016a7UDPm1QxBbGTNt5weY4F --- dev/configuration.distributed.json | 18 ++ dev/configuration.json | 9 + sql/Updates/Accounts/Rel21_02_002.sql | 57 +++++++ .../Mangos.Cluster.Admin/Auth/PeerAuth.cs | 60 +++++++ .../Commands/AdminCommand.cs | 130 +++++++++++++++ .../Commands/AdminCommandParser.cs | 139 ++++++++++++++++ .../Commands/AdminCommandReply.cs | 66 ++++++++ .../Commands/ConsoleAdminRepl.cs | 96 +++++++++++ .../Commands/IAdminCommandHandler.cs | 35 ++++ .../Mangos.Cluster.Admin.csproj | 14 ++ .../Protocol/AdminMethodId.cs | 65 ++++++++ .../Protocol/FederationLink.cs | 155 ++++++++++++++++++ .../Protocol/FederationServer.cs | 107 ++++++++++++ .../Protocol/PeerHello.cs | 98 +++++++++++ .../Mangos.Cluster/LegacyClusterModule.cs | 9 + .../Mangos.Cluster/Mangos.Cluster.csproj | 1 + .../Supervision/ClusterAdminCommandHandler.cs | 148 +++++++++++++++++ .../Globals/MangosGlobalConstants.cs | 2 +- .../FederationConfiguration.cs | 67 ++++++++ .../MangosConfiguration.cs | 6 + .../Mangos.Configuration/configuration.json | 9 + src/server/Mangos.sln | 7 + src/server/WorldCluster/Program.cs | 34 ++++ src/server/WorldCluster/WorldCluster.csproj | 1 + 24 files changed, 1332 insertions(+), 1 deletion(-) create mode 100644 sql/Updates/Accounts/Rel21_02_002.sql create mode 100644 src/server/Mangos.Cluster.Admin/Auth/PeerAuth.cs create mode 100644 src/server/Mangos.Cluster.Admin/Commands/AdminCommand.cs create mode 100644 src/server/Mangos.Cluster.Admin/Commands/AdminCommandParser.cs create mode 100644 src/server/Mangos.Cluster.Admin/Commands/AdminCommandReply.cs create mode 100644 src/server/Mangos.Cluster.Admin/Commands/ConsoleAdminRepl.cs create mode 100644 src/server/Mangos.Cluster.Admin/Commands/IAdminCommandHandler.cs create mode 100644 src/server/Mangos.Cluster.Admin/Mangos.Cluster.Admin.csproj create mode 100644 src/server/Mangos.Cluster.Admin/Protocol/AdminMethodId.cs create mode 100644 src/server/Mangos.Cluster.Admin/Protocol/FederationLink.cs create mode 100644 src/server/Mangos.Cluster.Admin/Protocol/FederationServer.cs create mode 100644 src/server/Mangos.Cluster.Admin/Protocol/PeerHello.cs create mode 100644 src/server/Mangos.Cluster/Supervision/ClusterAdminCommandHandler.cs create mode 100644 src/server/Mangos.Configuration/FederationConfiguration.cs diff --git a/dev/configuration.distributed.json b/dev/configuration.distributed.json index 36c73688..33c8eec4 100644 --- a/dev/configuration.distributed.json +++ b/dev/configuration.distributed.json @@ -12,6 +12,24 @@ "CharacterDatabase": "root;rootpass;mysql;3306;mangosVBcharacters;MySQL", "WorldDatabase": "root;rootpass;mysql;3306;mangosVBworld;MySQL" }, + "Federation": { + "Enabled": false, + "LocalClusterId": 1, + "LocalDisplayTag": "MS", + "ListenAddress": "0.0.0.0", + "ListenPort": 50101, + "MarkerMode": "ClientPreference", + "Peers": [] + }, + "Supervisor": { + "Enabled": false, + "HeartbeatIntervalMs": 5000, + "StaleAfterMissed": 3, + "DeadAfterMissed": 5, + "RespawnBackoffStepMs": 2000, + "RespawnBackoffMaxMs": 60000, + "Worlds": [] + }, "World": { "ClusterConnectHost": "cluster", "ClusterConnectPort": 50001, diff --git a/dev/configuration.json b/dev/configuration.json index 15817bb0..9848c719 100644 --- a/dev/configuration.json +++ b/dev/configuration.json @@ -12,6 +12,15 @@ "CharacterDatabase": "root;rootpass;mysql;3306;mangosVBcharacters;MySQL", "WorldDatabase": "root;rootpass;mysql;3306;mangosVBworld;MySQL" }, + "Federation": { + "Enabled": false, + "LocalClusterId": 1, + "LocalDisplayTag": "MS", + "ListenAddress": "0.0.0.0", + "ListenPort": 50101, + "MarkerMode": "ClientPreference", + "Peers": [] + }, "Supervisor": { "Enabled": false, "HeartbeatIntervalMs": 5000, diff --git a/sql/Updates/Accounts/Rel21_02_002.sql b/sql/Updates/Accounts/Rel21_02_002.sql new file mode 100644 index 00000000..c2cca8d7 --- /dev/null +++ b/sql/Updates/Accounts/Rel21_02_002.sql @@ -0,0 +1,57 @@ +-- +-- Federation support: peer-cluster admin endpoints + per-realm display +-- markers + per-account opt-in for showing those markers. +-- +-- Applied as part of the world-cluster proxy refactor (PR #4). +-- Idempotent: safe to re-run after a partial apply. +-- + +-- Realmlist: cluster identity, federation listener address, and the short +-- tag that's prepended/appended to player names when chat or roster info +-- is replicated cross-realm. +ALTER TABLE `realmlist` + ADD COLUMN IF NOT EXISTS `clusterId` INT UNSIGNED NOT NULL DEFAULT 0 + COMMENT 'Federation cluster id;

Adds the in-game entry point for the admin command surface introduced in PR #4 so a GM can list worlds, restart instances, and (with --realm) target a peer cluster without leaving the client. Wire-level: ICluster gains a single new control RPC, RunAdminCommand(byte[]) -> byte[]. The world serializes an AdminCommand, calls the cluster, and the cluster's WorldServerClass forwards to the locally-registered IAdminCommandHandler. Same handler used by the console REPL and inbound federation calls, so all three entry points share one execution path. In-game: new partial class WS_Commands.Admin.cs registers three [ChatCommand] entries - .server, .instance, .realm - all gated at AccessLevel.Admin. Each forwards the raw arguments through the shared AdminCommandParser. Reply lines are echoed back through character.CommandResponse so the GM sees a status header followed by the individual reply lines. Cross-realm: passing --realm N on any of the commands sets AdminCommand.TargetRealmId; PR #4's ClusterAdminCommandHandler will route to the peer once the federation table lookup lands (planned in PR #6 since it ships alongside chat federation that needs the same table). Local-cluster commands work today. New project reference: Mangos.World -> Mangos.Cluster.Admin. No source cycles introduced; Mangos.Cluster.Admin only references Mangos.Cluster.Interop (the contracts project) so the layering stays flat. https://claude.ai/code/session_016a7UDPm1QxBbGTNt5weY4F --- .../Dispatchers/ClusterInteropDispatcher.cs | 7 ++ src/server/Mangos.Cluster.Interop/ICluster.cs | 3 + .../Protocol/InteropMethodId.cs | 3 + .../Proxies/ClusterInteropProxy.cs | 10 +++ .../Network/WorldServerClass.cs | 35 +++++++- .../Handlers/WS_Commands.Admin.cs | 80 +++++++++++++++++++ .../Mangos.World/Handlers/WS_Commands.cs | 2 +- src/server/Mangos.World/Mangos.World.csproj | 1 + 8 files changed, 139 insertions(+), 2 deletions(-) create mode 100644 src/server/Mangos.World/Handlers/WS_Commands.Admin.cs diff --git a/src/server/Mangos.Cluster.Interop/Dispatchers/ClusterInteropDispatcher.cs b/src/server/Mangos.Cluster.Interop/Dispatchers/ClusterInteropDispatcher.cs index ebd8d5d2..97be669e 100644 --- a/src/server/Mangos.Cluster.Interop/Dispatchers/ClusterInteropDispatcher.cs +++ b/src/server/Mangos.Cluster.Interop/Dispatchers/ClusterInteropDispatcher.cs @@ -185,6 +185,13 @@ public ClusterInteropDispatcher(ICluster cluster, InteropConnection connection) return null; } + case InteropMethodId.ControlRunAdminCommand: + { + var cmdBytes = InteropSerializer.ReadByteArray(br); + var reply = _cluster.RunAdminCommand(cmdBytes); + return InteropSerializer.WriteByteArray(reply); + } + default: return null; } diff --git a/src/server/Mangos.Cluster.Interop/ICluster.cs b/src/server/Mangos.Cluster.Interop/ICluster.cs index 1f18f2a8..c056903c 100644 --- a/src/server/Mangos.Cluster.Interop/ICluster.cs +++ b/src/server/Mangos.Cluster.Interop/ICluster.cs @@ -86,4 +86,7 @@ public interface ICluster [Description("Control: a battlefield has finished.")] void BattlefieldFinish(int battlefieldId); + + [Description("Control: run an admin command on the cluster (or route to a peer); returns serialized AdminCommandReply.")] + byte[] RunAdminCommand(byte[] commandBytes); } diff --git a/src/server/Mangos.Cluster.Interop/Protocol/InteropMethodId.cs b/src/server/Mangos.Cluster.Interop/Protocol/InteropMethodId.cs index b78ee0f0..195b68a4 100644 --- a/src/server/Mangos.Cluster.Interop/Protocol/InteropMethodId.cs +++ b/src/server/Mangos.Cluster.Interop/Protocol/InteropMethodId.cs @@ -92,6 +92,9 @@ public enum InteropMethodId : ushort ControlBattlefieldJoin = 0x023D, ControlBattlefieldLeave = 0x023E, + // World -> cluster (admin) + ControlRunAdminCommand = 0x0240, + // ----- Framing ----------------------------------------------------- Response = 0xFFFF, } diff --git a/src/server/Mangos.Cluster.Interop/Proxies/ClusterInteropProxy.cs b/src/server/Mangos.Cluster.Interop/Proxies/ClusterInteropProxy.cs index ed2bc688..7ce47ad3 100644 --- a/src/server/Mangos.Cluster.Interop/Proxies/ClusterInteropProxy.cs +++ b/src/server/Mangos.Cluster.Interop/Proxies/ClusterInteropProxy.cs @@ -212,4 +212,14 @@ public void BattlefieldFinish(int battlefieldId) _connection.SendOneWayAsync(InteropMethodId.ControlBattlefieldFinish, ms.ToArray()).GetAwaiter().GetResult(); } + + public byte[] RunAdminCommand(byte[] commandBytes) + { + var response = _connection.SendRequestAsync( + InteropMethodId.ControlRunAdminCommand, + InteropSerializer.WriteByteArray(commandBytes)).GetAwaiter().GetResult(); + using var rms = new MemoryStream(response); + using var br = new BinaryReader(rms); + return InteropSerializer.ReadByteArray(br); + } } diff --git a/src/server/Mangos.Cluster/Network/WorldServerClass.cs b/src/server/Mangos.Cluster/Network/WorldServerClass.cs index 6700b3ea..c362a89d 100644 --- a/src/server/Mangos.Cluster/Network/WorldServerClass.cs +++ b/src/server/Mangos.Cluster/Network/WorldServerClass.cs @@ -20,6 +20,7 @@ using System.Collections; using System.Collections.Generic; using System.Threading; +using Mangos.Cluster.Admin.Commands; using Mangos.Cluster.Globals; using Mangos.Cluster.Interop; using Mangos.Cluster.Supervision; @@ -33,14 +34,19 @@ public class WorldServerClass : ICluster { private readonly ClusterServiceLocator _clusterServiceLocator; private readonly WorldSupervisor?

Lays the federation Phase A groundwork: whisper/party/raid envelopes, group invite/roster replication envelopes, presence queries, the cluster-side router, and the in-game .realm marker preference toggle. Wire format (federation transport, AdminMethodId 0x0320-0x037F): * ChatEnvelope: SenderRealmId/Tag, SenderGuid/Name, Channel (whisper/party/raid/guild/etc), recipient name+guid, group id, language, body. Marker tag set by sender; receiving cluster applies its local marker policy. * GroupInviteEnvelope / GroupInviteResponseEnvelope / GroupRosterUpdateEnvelope: shape the leader-cluster -> peer-cluster flow for forming and replicating cross-realm groups. Roster updates are authoritative snapshots; receivers overwrite local state. * PresenceQuery / PresenceReply: lookup-by-name across realms, used for whisper resolution and invite addressing. Cluster side: * FederationRouter (Mangos.Cluster/Federation/) maintains dial-out links by clusterId, multiplexes envelopes, and lazily reconnects. * RealmMarkers.Decorate centralises tag rendering with FederationMarkerMode (Always / ClientPreference / Off) and whisper-always-shows-tag carve-out so reply targeting still works even when markers are disabled. * WC_Handlers_Chat.TryRouteFederatedWhisper intercepts a "Name-RealmTag" form when no local character matches, builds a ChatEnvelope, and ships it via the router. Best-effort delivery; unreachable peers fall through to SMSG_CHAT_PLAYER_NOT_FOUND so the client experience matches today's behaviour. * FederationServer accepts inbound peer dials and now exposes OnLinkAccepted so the router can attach handlers per link. * WorldCluster/Program.cs wires the router into both inbound (FederationServer.OnLinkAccepted) and outbound paths. World side: * ICluster gains RouteFederatedChat / RouteFederatedGroupInvite control RPCs (0x0241 / 0x0242) so the world can hand the cluster an envelope without learning federation internals. * WS_Commands.Admin.cs's .realm command now accepts show/hide at Player access (own-marker preference) and list/peers at Admin level. The cluster-side handler stubs the per-account DB write - schema landed in PR #4 (account.federation_show_markers); wiring the actual UPDATE through the calling player's account row is a follow-up since AdminCommand doesn't carry an invoker today. Cross-realm admin: AdminCommand.TargetRealmId != 0 routes through FederationRouter.GetOrOpenAsync (PR #5 left this unrouted; PR #6 plumbs it). Endpoint resolution (realmId -> host:port) is stubbed at DI registration; the realmlist DB lookup lands as a follow-up that doesn't touch this PR's wire format. What's deliberately not in this PR: * Group accept popup integration: the GroupInviteEnvelope arrives at the recipient cluster but PR #6 doesn't yet pop a client-side dialog. The envelope shape is final so the gameplay-side bind is drop-in. * Phase B shard co-location (the heavy "make grouped players share an instance shard" path). The Shard envelopes carry method-ids 0x0360+ but no consumers yet. https://claude.ai/code/session_016a7UDPm1QxBbGTNt5weY4F --- .../Commands/AdminCommand.cs | 2 + .../Commands/AdminCommandParser.cs | 3 + .../Protocol/ChatEnvelope.cs | 110 +++++++++++ .../Protocol/FederationLink.cs | 70 +++++++ .../Protocol/FederationServer.cs | 4 + .../Protocol/GroupEnvelope.cs | 184 ++++++++++++++++++ .../Protocol/PresenceEnvelope.cs | 81 ++++++++ .../Dispatchers/ClusterInteropDispatcher.cs | 16 ++ src/server/Mangos.Cluster.Interop/ICluster.cs | 6 + .../Protocol/InteropMethodId.cs | 5 + .../Proxies/ClusterInteropProxy.cs | 20 ++ .../Federation/FederationRouter.cs | 140 +++++++++++++ .../Mangos.Cluster/Federation/RealmMarkers.cs | 66 +++++++ .../Handlers/WC_Handlers_Chat.cs | 57 +++++- .../Mangos.Cluster/LegacyClusterModule.cs | 19 ++ .../Network/WorldServerClass.cs | 62 +++++- .../Supervision/ClusterAdminCommandHandler.cs | 14 ++ .../Handlers/WS_Commands.Admin.cs | 19 +- src/server/WorldCluster/Program.cs | 3 + 19 files changed, 876 insertions(+), 5 deletions(-) create mode 100644 src/server/Mangos.Cluster.Admin/Protocol/ChatEnvelope.cs create mode 100644 src/server/Mangos.Cluster.Admin/Protocol/GroupEnvelope.cs create mode 100644 src/server/Mangos.Cluster.Admin/Protocol/PresenceEnvelope.cs create mode 100644 src/server/Mangos.Cluster/Federation/FederationRouter.cs create mode 100644 src/server/Mangos.Cluster/Federation/RealmMarkers.cs diff --git a/src/server/Mangos.Cluster.Admin/Commands/AdminCommand.cs b/src/server/Mangos.Cluster.Admin/Commands/AdminCommand.cs index d2c97c48..4388c619 100644 --- a/src/server/Mangos.Cluster.Admin/Commands/AdminCommand.cs +++ b/src/server/Mangos.Cluster.Admin/Commands/AdminCommand.cs @@ -127,4 +127,6 @@ public enum AdminVerb : ushort // .realm RealmList = 0x0020, RealmPeers = 0x0021, + RealmMarkerShow = 0x0022, + RealmMarkerHide = 0x0023, } diff --git a/src/server/Mangos.Cluster.Admin/Commands/AdminCommandParser.cs b/src/server/Mangos.Cluster.Admin/Commands/AdminCommandParser.cs index cc3dc197..238ba440 100644 --- a/src/server/Mangos.Cluster.Admin/Commands/AdminCommandParser.cs +++ b/src/server/Mangos.Cluster.Admin/Commands/AdminCommandParser.cs @@ -110,6 +110,9 @@ public static bool TryParse(string input, out AdminCommand? command, out string?

Each piece is small enough to land on its own; bundled here because they share the same DI graph and config. * Local realm id provider now reads cfg.Federation.LocalClusterId instead of hard-coded 0, so .realm list / cross-realm dispatch sees the right id. * Mangos.MySql gains two new commands (IGetFederationPeersQuery and IUpdateFederationMarkerCommand) plus their .sql resources. Queries follow the existing Dapper pattern (UpdateAccountCommand etc.). * FederationRouter now optionally takes IGetFederationPeersQuery, starts a 60-second refresh loop in StartAsync(), and consults its PeerInfo cache before falling back to the caller-supplied lambda. GetOrOpenAsync resolves clusterId -> endpoint from realmlist. WorldCluster/Program.cs awaits federationRouter.StartAsync(). * WS_Commands.Admin.cs's `.realm show / .realm hide` now flips account.federation_show_markers via the new MySql command, resolving the calling player's account through character.client .Account. Persists across logins. ClusterAdminCommandHandler's RealmMarker verb retains the cross-realm flow for operators flipping a remote account via --account . * GetServerInfo now reports BATTLEGROUNDs.Count instead of zero so the supervisor's load-aware placement sees real BG load. * Federated group invites: FederatedGroupInviter binds onto FederationRouter.OnGroupInvite, finds the local recipient, and sends SMSG_GROUP_INVITE so the standard popup appears with the leader's name prefixed by their realm tag. Replies to the leader's cluster with a GroupInviteResponseEnvelope. Outbound side: the existing CMSG_GROUP_INVITE handler now detects "Name-RealmTag" patterns (numeric clusterId or textual displayTag) and forwards via the router. Same Name-RealmTag tag-name resolution applied to the whisper path. * Phase B shard scaffold: ShardClaim / ShardRelease envelopes (AdminMethodId 0x0360/0x0361), FederationLink dispatch, and an in-memory ShardRegistry that tracks (mapId, shardKey) -> owner cluster + relay endpoint. Bound at cluster startup. The world's enter-zone path will consult ShardRegistry.GetShard in a follow-up PR; this commit lays the wire format and registry so that follow-up is a one-file add. Cycle audit: Mangos.Cluster -> Mangos.Cluster.Admin and Mangos.MySql; both already referenced. Mangos.World -> Mangos.MySql already referenced.

Build verified locally: dotnet build of Mangos.sln passes with 0 errors and all 15 existing tests still green; the 106 remaining warnings are all pre-existing legacy code (deprecated SQL.Query and unused fields). What changed: * ClusterAdminCommandHandler: implements every previously-stubbed AdminVerb. ServerClaimMaps asks a world to host a comma-separated --maps list. InstanceSpawn picks the least-loaded eligible world via the supervisor's load heuristic. InstanceShutdown / InstanceRestart fan out to every world that claims the map. InstanceInfo reports hosting world plus any active shard claim. InstanceKick is a hint alias for shutdown. RealmList now lists peers (clusterId, tag, endpoint) when federation is on. RealmPeers shows live authenticated links from the router's Peers map. RealmMarker accepts --account for cross-realm operator overrides and points self-toggle users at the in-game .realm show / .realm hide. * FederatedChatDeliverer wires onto FederationRouter.OnChat and delivers every inbound envelope as a standard SMSG_MESSAGECHAT to the local recipient(s). Whisper -> single recipient by name; Party / Raid -> all local members of the federated group; System -> broadcast. Marker rendering goes through RealmMarkers.Decorate so whispers always carry the [tag] regardless of preference. * Federated invite accept/decline now closes the loop. Inviter remembers each pending invite by recipient guid; the cluster's CMSG_GROUP_ACCEPT and CMSG_GROUP_DECLINE handlers consult TryHandleAccept/TryHandleDecline first and short-circuit to a GroupInviteResponseEnvelope back to the leader's cluster, instead of crashing on the missing local Group object. * FederationRouter.StartAsync now spins both a peer-table refresh loop (60s realmlist DB poll) and a maintenance loop (15s) that proactively dials every known peer and heartbeats live links via the new FederationLink.HeartbeatAsync. Failed heartbeats drop the link so the next iteration redials. Routes around peer outages without operator intervention. * WorldCluster/Program.cs binds the new chat deliverer alongside the existing inviter and shard registry hookups. No new project references; layering unchanged. https://claude.ai/code/session_016a7UDPm1QxBbGTNt5weY4F --- .../Protocol/FederationLink.cs | 4 + .../Federation/FederatedChatDeliverer.cs | 196 ++++++++++++++++++ .../Federation/FederatedGroupInviter.cs | 65 ++++-- .../Federation/FederationRouter.cs | 44 +++- .../Handlers/WC_Handlers_Group.cs | 24 ++- .../Mangos.Cluster/LegacyClusterModule.cs | 7 +- .../Supervision/ClusterAdminCommandHandler.cs | 155 +++++++++++++- src/server/WorldCluster/Program.cs | 4 + 8 files changed, 477 insertions(+), 22 deletions(-) create mode 100644 src/server/Mangos.Cluster/Federation/FederatedChatDeliverer.cs diff --git a/src/server/Mangos.Cluster.Admin/Protocol/FederationLink.cs b/src/server/Mangos.Cluster.Admin/Protocol/FederationLink.cs index 4e49c25a..69469e4e 100644 --- a/src/server/Mangos.Cluster.Admin/Protocol/FederationLink.cs +++ b/src/server/Mangos.Cluster.Admin/Protocol/FederationLink.cs @@ -153,6 +153,10 @@ public async Task QueryPresenceAsync(PresenceQueryEnvelop return PresenceReplyEnvelope.Deserialize(bytes); } + /// Liveness check; peer responds with an empty body. + public Task HeartbeatAsync(int timeoutMs = 5000) + => _connection.SendRequestAsync((InteropMethodId)AdminMethodId.PeerHeartbeat, Array.Empty(), timeoutMs); + /// Phase B: claim a shard for a federated group. public Task SendShardClaimAsync(ShardClaimEnvelope env) => _connection.SendOneWayAsync((InteropMethodId)AdminMethodId.ShardClaim, env.Serialize()); diff --git a/src/server/Mangos.Cluster/Federation/FederatedChatDeliverer.cs b/src/server/Mangos.Cluster/Federation/FederatedChatDeliverer.cs new file mode 100644 index 00000000..7ff1a97d --- /dev/null +++ b/src/server/Mangos.Cluster/Federation/FederatedChatDeliverer.cs @@ -0,0 +1,196 @@ +// +// Copyright (C) 2013-2025 getMaNGOS +// +// This program is free software.

The shard registry that arrived in PR #6 is now actually consulted when a player logs in, and the leader's cluster actually emits the claims that populate peer registries. Build verified: 0 errors, 15/15 tests pass. End-to-end flow once a federated group exists: 1. Leader on Cluster A invites a player on Cluster B; B accepts. 2. Cluster B's FederatedGroupInviter sends a GroupInviteResponseEnvelope with TargetRealmId = B's clusterId (previously left at 0). 3. Cluster A's new FederatedShardClaimer receives the response, looks up the leader by groupId, and emits a ShardClaimEnvelope keyed by (leader.Map, groupId) back to Cluster B. 4. Cluster B's ShardRegistry records the claim. 5. The Cluster-B player tries to log in to a character on that map. World's ClientLogin now asks ICluster.QueryShard(mapId, guid). 6. Cluster B's QueryShard resolves guid -> group -> shardKey, finds the registry entry, sees OwnerClusterId != local, returns ShardLookupResult { Kind = Foreign, OwnerClusterId, OwnerEndpoint, OwnerDisplayTag }. 7. World logs the result, sends a SMSG_MESSAGECHAT system message to the client telling them which realm hosts their group's instance, and calls cluster.ClientDrop so they reconnect via the standard realmlist flow on the host realm. Wire format: new InteropMethodId.ControlQueryShard (0x0243) with a ShardLookupResult payload (Kind + OwnerClusterId + OwnerEndpoint + OwnerDisplayTag). ICluster gains QueryShard; dispatcher and proxy extended; serializer gains Read/WriteShardLookupResult. WorldServerClass on the cluster side now takes a ShardRegistry and a local-cluster-id provider via DI. QueryShard walks WorldCluster .CharacteRs to resolve guid -> group, uses Group.Id as the shard key, looks up ShardRegistry.GetShard(mapId, shardKey), and compares OwnerClusterId against the local id from FederationConfiguration. Layering note: no new project references.

This commit is the result of running `dotnet format` on the solution; only whitespace and import ordering change. No semantic changes, no behaviour change, build still clean (0 errors), tests still 15/15 pass, and `dotnet format --verify-no-changes` now exits 0. Two pre-existing files in Mangos.MySql/Connections/ and Mangos.Tests/Logging/ also had stale formatting; the formatter normalised those too. https://claude.ai/code/session_016a7UDPm1QxBbGTNt5weY4F --- .../Commands/AdminCommand.cs | 30 ++++- .../Commands/AdminCommandReply.cs | 5 +- .../Protocol/ChatEnvelope.cs | 50 ++++++-- .../Protocol/FederationLink.cs | 55 +++++++-- .../Protocol/FederationServer.cs | 10 +- .../Protocol/GroupEnvelope.cs | 100 ++++++++++++---- .../Protocol/PeerHello.cs | 30 ++++- .../Protocol/PresenceEnvelope.cs | 30 ++++- .../Protocol/ShardEnvelope.cs | 35 ++++-- .../ShardLookupResult.cs | 10 +- .../Federation/FederatedGroupInviter.cs | 15 ++- .../Federation/FederationRouter.cs | 55 +++++++-- .../Federation/ShardRegistry.cs | 25 +++- .../Supervision/ClusterAdminCommandHandler.cs | 6 +- .../Supervision/SupervisedWorld.cs | 35 ++++-- .../Supervision/WorldSupervisor.cs | 10 +- .../FederationConfiguration.cs | 10 +- .../MangosConfiguration.cs | 15 ++- .../SupervisorConfiguration.cs | 15 ++- src/server/Mangos.Logging/IMangosLogger.cs | 2 +- .../Connections/CharacterConnection.cs | 4 +- .../Connections/WorldConnection.cs | 4 +- src/server/Mangos.MySql/DbVersionChecker.cs | 2 +- src/server/Mangos.MySql/SQL.cs | 108 ++++++++++-------- .../Mangos.Tests/Logging/LoggingTests.cs | 4 +- src/server/RealmServer/Program.cs | 2 +- src/server/WorldCluster/Program.cs | 2 +- 27 files changed, 506 insertions(+), 163 deletions(-) diff --git a/src/server/Mangos.Cluster.Admin/Commands/AdminCommand.cs b/src/server/Mangos.Cluster.Admin/Commands/AdminCommand.cs index 4388c619..d10d6c5e 100644 --- a/src/server/Mangos.Cluster.Admin/Commands/AdminCommand.cs +++ b/src/server/Mangos.Cluster.Admin/Commands/AdminCommand.cs @@ -33,22 +33,40 @@ namespace Mangos.Cluster.Admin.Commands; public sealed class AdminCommand { /// Stable verb identifier; see . - public required AdminVerb Verb { get; init; } + public required AdminVerb Verb + { + get; init; + } /// 0 = local cluster; otherwise route to the peer that owns this realm. - public uint TargetRealmId { get; init; } + public uint TargetRealmId + { + get; init; + } /// Optional: target a single world (e.g. .server shutdown --world W). - public string?
