be written, reviewed, and changed in this repository. + +## Go toolchain + formatting (non-negotiable) + +- **Always run `gofmt`** on changed Go files. +- **Use `goimports`** (or `gofmt` + manual imports) so imports are grouped and unused imports removed. +- **Prefer standard library** over new dependencies unless there’s a clear reason. +- **Keep `go.mod` tidy**: don’t add deps casually; when you do, keep versions minimal and coherent. + +## Code style + structure + +- **Small, focused diffs**: change the minimum surface area necessary. +- **Package boundaries**: prefer adding code to an existing relevant package over creating new packages. +- **Avoid cyclic dependencies**; keep `internal/...` layering clean. +- **Public API discipline**: + - Export only what must be used outside the package. + - Keep exported types/functions well-documented (GoDoc comment starting with the symbol name). +- **Naming**: + - Use Go conventions (short receiver names, no `GetX()` unless needed). + - Prefer clear domain names over generic ones (e.g., `RoomService` not `Service`). + +## Error handling (industry patterns) + +- **Return errors, don’t panic** in normal control flow. +- **Wrap errors with context** using `%w`: + - `return fmt.Errorf("doing X: %w", err)` +- **Use sentinel errors sparingly**; prefer typed errors only when callers must branch on type. +- **Don’t log and return the same error** unless you have a strong reason (avoid double logging). +- **Use `errors.Is` / `errors.As`** for comparisons. + +## Context, cancellation, timeouts + +- **Plumb `context.Context`** through call chains for IO, network, and long-running operations. +- **Never store `context.Context`** inside structs. +- **Always set timeouts** for network calls unless the caller explicitly controls it. +- **Select on `ctx.Done()`** in loops that can block or run indefinitely. + +## Concurrency hygiene + +- **Avoid goroutine leaks**: + - Always ensure goroutines can exit (ctx cancellation, closed channels, done signals). + - Prefer `errgroup.Group` for fan-out work with cancellation. +- **Prefer channels for ownership transfer**, not for shared mutable state. +- **Protect shared state** with `sync.Mutex`/`sync.RWMutex` or confine it to one goroutine. +- **Avoid data races**: design for correctness first; use `-race` when running tests. + +## Logging & observability + +- Use the project’s logging conventions (currently `slog`). +- Log **actionable** fields: + - request/connection identifiers where available + - addresses, user IDs, session IDs (avoid PII where possible) +- **Don’t log secrets** (passwords, tokens, private keys). +- Metrics: + - Prefer incrementing existing Prometheus metrics where appropriate instead of inventing new ones. + +## Networking & protocol code + +- Be strict on input validation at boundaries (HTTP params, websocket payloads, TCP packets). +- For protocol evolution: + - Add backwards-compatible fields where possible. + - Keep parsing resilient; fail fast with clear errors on malformed inputs. +- Avoid allocating in tight loops; reuse buffers when it materially improves hot paths. + +## Tests (expected behavior) + +- For new behavior, add or update tests close to the code: + - `*_test.go` in the same package unless black-box testing is required. +- Prefer table-driven tests for multiple cases. +- Verify error cases explicitly (invalid inputs, timeouts, empty states). +- Keep tests deterministic; avoid sleeps when possible. + +## Security expectations + +- Treat all external input as untrusted (HTTP, WS, TCP, DB). +- Never commit real credentials; use env vars/config where secrets are needed. +- Prefer constant-time comparisons for secrets if relevant. +- Validate/normalize user-controlled network addresses to avoid SSRF-like patterns. + +## Documentation when changing behavior + +- If you modify user-facing behavior (CLI flags, endpoints, defaults), update docs in `docs/`. +- Keep “incomplete/WIP” notes accurate—don’t over-promise. + +## How to work in this repository (practical) + +- Before large refactors, look for existing patterns in `internal/...` and follow them. +- When you touch the backend protocol handlers (`internal/backend/command_*.go`), prioritize: + - correctness + - compatibility with existing clients + - clear logging around handshake/session boundaries +

Relay/p2p end-to-end delivery remains broken (creator never learns the guest's fake-host IP; handleJoinRoom is a no-op) and is documented as a deferred finding. --- .github/workflows/ci.yml | 17 ++ Makefile | 4 +- cmd/integration-client/main.go | 432 +++++++++++++++++++++++++-- go.mod | 1 + go.sum | 2 + internal/backend/dispatcher.go | 14 +- internal/integration/helpers_test.go | 142 +++++++++ internal/integration/lan_test.go | 95 ++++++ internal/integration/spike_test.go | 22 +- 9 files changed, 674 insertions(+), 55 deletions(-) create mode 100644 internal/integration/helpers_test.go create mode 100644 internal/integration/lan_test.go diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 195f2a02..21c7e038 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -31,6 +31,23 @@ jobs: - name: Run Tests run: go test -v -cover -race ./... + integration: + runs-on: ubuntu-latest + timeout-minutes: 20 + needs: + - test + steps: + - uses: actions/checkout@v4 + + - name: Set up Go + uses: actions/setup-go@v5 + with: + go-version: "1.24" + + - name: Run multi-docker integration tests + # Docker is pre-installed on GitHub-hosted runners. + run: go test -tags=integration -run 'TestSpike|TestLANGameExchange' -v -timeout 300s -count=1 ./internal/integration/... + build: runs-on: ubuntu-latest timeout-minutes: 10 diff --git a/Makefile b/Makefile index 6037f54e..79fd4cf2 100644 --- a/Makefile +++ b/Makefile @@ -24,8 +24,8 @@ serve: test: go test -v --race ./... -test-integraiton: - go test -tags=integration -run TestSpike -v -timeout 300s -count=1 ./internal/integration/... +test-integration: + go test -tags=integration -run 'TestSpike|TestLANGameExchange' -v -timeout 300s -count=1 ./internal/integration/... lint: go tool golangci-lint run ./... diff --git a/cmd/integration-client/main.go b/cmd/integration-client/main.go index 59c2d1f3..981c885f 100644 --- a/cmd/integration-client/main.go +++ b/cmd/integration-client/main.go @@ -1,49 +1,427 @@ -// Command integration-client is the mock Gladiator game client used by the -// multi-docker integration tests.

This appears to be a partially started alternative to `proxy/p2p`. - **`proxy/relay`**: Relay mode for clients behind strict NAT. - **`proxy/direct`** (LAN mode): Works for local network scenarios. diff --git a/internal/backend/proxy/webrtc/webrtc.go b/internal/backend/proxy/webrtc/webrtc.go deleted file mode 100644 index f3511273..00000000 --- a/internal/backend/proxy/webrtc/webrtc.go +++ /dev/null @@ -1,71 +0,0 @@ -package webrtc - -import ( - "context" - - "github.com/dimspell/gladiator/gen/multi/v1/multiv1connect" - "github.com/dimspell/gladiator/internal/backend/bsession" - "github.com/dimspell/gladiator/internal/backend/proxy" - "github.com/dimspell/gladiator/internal/backend/redirect" - "github.com/dimspell/gladiator/internal/model" - "github.com/pion/webrtc/v4" -) - -type Factory struct { - ICEServers []webrtc.ICEServer - ProxyFactory redirect.ProxyFactory -} - -func (p *Factory) Mode() model.RunMode { return model.RunModeWebRTC } - -func (p *Factory) Create(session *bsession.Session, client multiv1connect.GameServiceClient) proxy.ProxyClient { - return &Instance{} -} - -type Instance struct { - ProxyFactory redirect.ProxyFactory - - Session *bsession.Session - - RoomID string - Peers map[string]*Peer -} - -func (p *Instance) CreateRoom(ctx context.Context, params proxy.CreateParams) error { - // TODO implement me - panic("implement me") -} - -func (p *Instance) SetRoomReady(ctx context.Context, params proxy.CreateParams) error { - // TODO implement me - panic("implement me") -} - -func (p *Instance) ListGames(ctx context.Context) ([]model.LobbyRoom, error) { - // TODO implement me - panic("implement me") -} - -func (p *Instance) GetGame(ctx context.Context, roomID string) (*model.LobbyRoom, []model.LobbyPlayer, error) { - // TODO implement me - panic("implement me") -} - -func (p *Instance) JoinGame(ctx context.Context, roomID string, password string) ([]model.LobbyPlayer, error) { - // TODO implement me - panic("implement me") -} - -func (p *Instance) Close() { - // TODO implement me - panic("implement me") -} - -func (p *Instance) Handle(ctx context.Context, payload []byte) error { - // TODO implement me - panic("implement me") -} - -type Peer struct { - ID string `json:"id"` -} From df3e6d51fa7f2789b2b175285535fdaca0db633c Mon Sep 17 00:00:00 2001 From: dimspell <141545384+dimspell@users.noreply.github.com> Date: Fri, 17 Jul 2026 09:17:23 +0200 Subject: [PATCH 087/102] Add disconnect status and cleanup on disconnect --- internal/console/room.go | 10 ++++++ internal/console/room_test.go | 60 +++++++++++++++++++++++++++++++++++ internal/console/session.go | 31 +++++++++++++++--- 3 files changed, 96 insertions(+), 5 deletions(-) diff --git a/internal/console/room.go b/internal/console/room.go index 26295338..fbae5fc3 100644 --- a/internal/console/room.go +++ b/internal/console/room.go @@ -505,6 +505,8 @@ func (mp *RoomService) HandleJoinLobby(ctx context.Context, session *UserSession // SetPlayerConnected notifies the user has connected to the lobby. func (mp *RoomService) SetPlayerConnected(session *UserSession) { + session.OnWriteError = func() { mp.SetPlayerDisconnected(session) } + players := mp.listSessions() mp.AddUserSession(session.UserID, session) @@ -530,12 +532,20 @@ func (mp *RoomService) SetPlayerConnected(session *UserSession) { // SetPlayerDisconnected notifies the user has left the lobby. func (mp *RoomService) SetPlayerDisconnected(session *UserSession) { + // Guard against double teardown: the OnWriteError goroutine and the + // HandleSession defer can both reach here for the same session. + if !session.disconnected.CompareAndSwap(false, true) { + slog.Debug("Session already disconnected", "user", session.UserID) + return + } + slog.Info("Closing player connection", "user", session.UserID) // Close the websocket connection if err := session.WebSocket.CloseNow(); err != nil { slog.Debug("Could not close the connection", "user", session.UserID, logging.Error(err)) } + session.WebSocket = nil // Kick the user from the game room (if any) mp.LeaveRoom(context.Background(), session) diff --git a/internal/console/room_test.go b/internal/console/room_test.go index 248fb291..2eccc2d4 100644 --- a/internal/console/room_test.go +++ b/internal/console/room_test.go @@ -4,6 +4,7 @@ import ( "context" "fmt" "sync" + "sync/atomic" "testing" "time" @@ -314,3 +315,62 @@ func TestHandleRelayLeaveRemovesUser(t *testing.T) { _, found := room.Players[1] require.False(t, found) } + +// TestSendWriteErrorTearsDownSession verifies that a failed websocket write +// triggers the OnWriteError callback (wired like SetPlayerConnected does) and +// that the dead session is removed from the session map.
