From e8ced744292e8d991173d973ce63ec9d048343ea Mon Sep 17 00:00:00 2001 From: Joshua Date: Fri, 8 May 2026 19:58:06 -0400 Subject: [PATCH] CUB-123: integrate gateway, wire PostgreSQL repositories, add SSE streaming - Create repository/ package with pgx-backed CRUD for agents, sessions, tasks, projects - Define AgentRepo/SessionRepo/TaskRepo/ProjectRepo interfaces - Update handler to use repository interfaces instead of in-memory stores - Add SSE broker with GET /api/events endpoint (text/event-stream) - Add gateway client that polls OpenClaw for agent states - Add GATEWAY_URL and GATEWAY_POLL_INTERVAL config fields - Seed 5 demo agents (Otto, Rex, Dex, Hex, Pip) on empty DB - Update router to wire SSE broker - All 21 handler tests pass with mock repos --- go-backend/cmd/server/main.go | 64 +++-- go-backend/internal/config/config.go | 34 ++- go-backend/internal/gateway/client.go | 198 +++++++++++++++ go-backend/internal/handler/agent.go | 84 ++++--- go-backend/internal/handler/handler_test.go | 34 ++- .../internal/handler/mock_repos_test.go | 235 ++++++++++++++++++ go-backend/internal/handler/project.go | 11 +- go-backend/internal/handler/session.go | 11 +- go-backend/internal/handler/sse.go | 125 ++++++++++ go-backend/internal/handler/task.go | 11 +- .../internal/repository/agent_repository.go | 186 ++++++++++++++ go-backend/internal/repository/interfaces.go | 38 +++ .../internal/repository/project_repository.go | 94 +++++++ .../internal/repository/session_repository.go | 78 ++++++ .../internal/repository/task_repository.go | 85 +++++++ go-backend/internal/router/router.go | 28 ++- 16 files changed, 1207 insertions(+), 109 deletions(-) create mode 100644 go-backend/internal/gateway/client.go create mode 100644 go-backend/internal/handler/mock_repos_test.go create mode 100644 go-backend/internal/handler/sse.go create mode 100644 go-backend/internal/repository/agent_repository.go create mode 100644 go-backend/internal/repository/interfaces.go create mode 100644 go-backend/internal/repository/project_repository.go create mode 100644 go-backend/internal/repository/session_repository.go create mode 100644 go-backend/internal/repository/task_repository.go diff --git a/go-backend/cmd/server/main.go b/go-backend/cmd/server/main.go index 2dcc49e..dc760b4 100644 --- a/go-backend/cmd/server/main.go +++ b/go-backend/cmd/server/main.go @@ -13,9 +13,10 @@ import ( "code.cubecraftcreations.com/CubeCraft-Creations/Control-Center/go-backend/internal/config" "code.cubecraftcreations.com/CubeCraft-Creations/Control-Center/go-backend/internal/db" + "code.cubecraftcreations.com/CubeCraft-Creations/Control-Center/go-backend/internal/gateway" "code.cubecraftcreations.com/CubeCraft-Creations/Control-Center/go-backend/internal/handler" + "code.cubecraftcreations.com/CubeCraft-Creations/Control-Center/go-backend/internal/repository" "code.cubecraftcreations.com/CubeCraft-Creations/Control-Center/go-backend/internal/router" - "code.cubecraftcreations.com/CubeCraft-Creations/Control-Center/go-backend/internal/store" ) func main() { @@ -28,32 +29,51 @@ func main() { })) slog.SetDefault(logger) - // ── Database (optional until CUB-120 schema is ready) ────────────────── - var pool *db.Pool - if cfg.DatabaseURL != "" { - var err error - pool, err = db.New(cfg.DatabaseURL) - if err != nil { - slog.Warn("database connection failed;
