Replaced legacy Spring Boot backend.\n**Stack:** Go 1.24, net/http (std lib), GORM + SQLite/PostgreSQL (glebarez/sqlite - CGO-free).\n\n## STRUCTURE\n```\ngo-backend/\n├── cmd/paneld/main.go # Entry point; starts HTTP server + WebSocket\n├── internal/\n│ ├── http/ # HTTP layer\n│ │ ├── router.go # Routes (NewServeMux) + Middleware chain\n│ │ ├── handler/ # API Handlers (User, Tunnel, Node, etc.)\n│ │ ├── middleware/ # JWT, CORS, Logging, Recover\n│ │ └── response/ # JSON response helpers\n│ ├── store/\n│ │ ├── model/model.go # GORM model structs (single source of truth)\n│ │ └── repo/ # Data Access Layer (Repository pattern, GORM)\n│ │ ├── repository.go # Core queries, Open/OpenPostgres, AutoMigrate (83k LOC)\n│ │ ├── repository_mutations.go # Mutation helpers (user/node/tunnel/forward CRUD, 43k LOC)\n│ │ ├── repository_federation.go # Federation-specific queries\n│ │ ├── repository_flow.go # Flow/forward status queries\n│ │ ├── repository_control.go # Control plane queries\n│ │ └── repository_groups.go # Group management queries\n│ └── auth/ # Auth logic\n├── tests/contract/ # Integration/contract tests (14 tests)\n├── Dockerfile # Multi-stage build (golang:1.24-bookworm → debian:bookworm-slim)\n└── Makefile # Build commands\n```\n\n## WHERE TO LOOK\n| Task | Location | Notes |\n|------|----------|-------|\n| **API Routes** | `go-backend/internal/http/router.go` | Registers handlers to `http.ServeMux` |\n| **DB Models** | `go-backend/internal/store/model/model.go` | GORM structs with `TableName()` methods |\n| **Repository** | `go-backend/internal/store/repo/` | GORM-based queries, all DB ops encapsulated |\n| **Auth Middleware** | `go-backend/internal/http/middleware/jwt.go` | Extracts `Authorization` header |\n| **WebSocket** | `go-backend/internal/ws/` | Real-time updates (traffic, status) |\n| **Contract Tests** | `go-backend/tests/contract/` | Integration tests for auth, federation, tunnels |\n\n## CONVENTIONS\n- **GORM ORM**: Uses GORM with `glebarez/sqlite` (CGO-free) and `gorm.io/driver/postgres`.\n- **AutoMigrate**: Schema created at startup via `autoMigrateAll()` — no hand-written DDL.\n- **TableName()**: All models define explicit `TableName()` returning singular snake_case names.\n- **Repository Pattern**: Handlers never access `*gorm.DB` directly — all queries go through `repo.Repository` methods.\n- **Standard Lib**: Uses `net/http` for routing (Go 1.22+ patterns).\n- **Auth**: Expects raw JWT in `Authorization` header (no `Bearer` prefix).\n- **API Envelope**: All responses use `response.R{code, msg, data, ts}` structure.\n- **Config**: Loaded from environment variables (see `cmd/paneld/main.go`).\n- **SQLite Constraints**: `MaxOpenConns(1)`, WAL mode, busy_timeout=5000.\n- **PostgreSQL**: Supported via `DB_TYPE=postgres` and `DATABASE_URL` env vars.\n\n## ANTI-PATTERNS\n- **DO NOT** let handlers call `repo.DB()` directly — add a Repository method instead.\n- **DO NOT CHANGE** handler signatures without updating `router.go`.\n- **DO NOT** use `type:jsonb` or `type:serial` in GORM tags (SQLite incompatible).\n- **DO NOT** omit `TableName()` on new models — GORM pluralizes by default.\n\n## COMMANDS\n```bash\ncd go-backend\ngo run ./cmd/paneld # Default: SERVER_ADDR=:6365\ngo test ./... # Unit tests\ngo test ./tests/contract/... # Contract tests\nmake build\n```\n\n</system-reminder>",

"text": "这个报错我确认到了，根因是 **SQLite 旧库升级路径漏加了 `node.extra_ips` 列**。\n\n你这个场景不是新库初始化（新库会按模型建表），而是旧库启动时走 `prepareSQLiteLegacyColumns` 补列逻辑；之前这里只补了 `ServerIPV4/ServerIPV6/...`，没补 `ExtraIPs`，所以写入时报：\n\n- `SQL logic error: no such column: extra_ips (1)`\n\n我已经修复了：\n\n- 在 `go-backend/internal/store/repo/repository.go:263` 的 SQLite 兼容补列列表里加入了 `ExtraIPs`。\n- 已执行并通过迁移相关测试：`go test ./internal/store/repo -run \"TestMigrateSchema|TestMigrate\"`。\n\n你现在要做的只有一步：\n\n- 重启后端服务（让启动时迁移逻辑执行一次），比如重新启动 `paneld` / 容器。\n\n重启后再去“节点 -> 额外IP”保存，应该就不会再报这个错了。 \n如果你愿意，我也可以再帮你快速加一个回归测试，专门覆盖“旧 SQLite 库缺 `extra_ips` 自动补列”这个场景，避免以后再回归。",

"text": "已完成这一轮“跨表全量列对比（model vs 旧库补列逻辑）”，并做了可执行验证。\n\n我做了什么：\n\n- 对比了 `model.Node` / `model.Tunnel` 字段与 `prepareSQLiteLegacyColumns` 的补列清单。\n- 结论：\n - `Node` 目前应补的历史增量列：`server_ip_v4`, `server_ip_v6`, `extra_ips`, `tcp_listen_addr`, `udp_listen_addr`, `inx`, `is_remote`, `remote_url`, `remote_token`, `remote_config`\n - `Tunnel` 应补：`inx`, `ip_preference`\n- 我已把这个对齐结果固化为回归测试，新增了一个“更老版本库”场景验证：\n - 新测试：`TestOpenMigratesVeryLegacyNodeAndTunnelColumns`\n - 文件：`go-backend/tests/contract/migration_contract_test.go`\n - 该测试从极简旧表结构启动，验证上述所有列都会被自动补齐。\n- 测试结果：通过\n - `go test ./tests/contract -run \"TestOpenMigratesLegacyNodeDualStackColumns|TestOpenMigratesVeryLegacyNodeAndTunnelColumns\"`\n\n最终结论（本轮排查范围内）：\n\n- **Node/Tunnel 这条旧库升级链路已对齐且有测试兜底**。\n- 你这类 “no such column” 的同类风险，针对这两个核心表已经基本封住。",
