From 8b8a2aa3fa5e5ab7bbd2e0458ab15315243cdccf Mon Sep 17 00:00:00 2001 From: Haitao Pan Date: Thu, 5 Feb 2026 08:34:25 +0800 Subject: [PATCH] feat(agent-persistence): implement PostgreSQL persistence for agent registry Core Changes: - Add Agent struct and management methods to Store interface - Implement PostgreSQL store methods (UpsertAgent, ListAgents, DeleteAgent, DeleteStaleAgents) - Integrate persistence into Registry with async database writes - Add Load() method to restore agents from database on startup - Implement runAgentCleanup background task (5min interval, 10min stale threshold) Database: - Update agents table schema to use JSONB for groups field - Add indexes on last_heartbeat and healthy columns - Support health tracking and automatic cleanup of stale agents Documentation: - Add comprehensive DB access and upgrade guide - Include agent persistence implementation plan - Document diagnostic procedures and troubleshooting steps - Add walkthrough of multi-agent support implementation This enables: - Persistent agent state across service restarts - Automatic cleanup of offline agents - Multi-agent support with shared token authentication --- .agent/docs/agent_persistence_plan.md | 348 +++++++++++++++++++ .agent/docs/db-access-and-upgrade.md | 81 +++++ .agent/docs/diagnostic_report.md | 214 ++++++++++++ .agent/docs/walkthrough.md | 477 ++++++++++++++++++++++++++ cmd/accountsvc/main.go | 35 ++ internal/agentserver/registry.go | 87 +++++ internal/store/postgres.go | 87 +++++ internal/store/store.go | 100 ++++++ sql/20260205_agents_table.sql | 2 +- 9 files changed, 1430 insertions(+), 1 deletion(-) create mode 100644 .agent/docs/agent_persistence_plan.md create mode 100644 .agent/docs/db-access-and-upgrade.md create mode 100644 .agent/docs/diagnostic_report.md create mode 100644 .agent/docs/walkthrough.md diff --git a/.agent/docs/agent_persistence_plan.md b/.agent/docs/agent_persistence_plan.md new file mode 100644 index 0000000..57a313c --- /dev/null +++ b/.agent/docs/agent_persistence_plan.md @@ -0,0 +1,348 @@ +# Agent Persistence Implementation Plan + +## 目标 + +将 agent 注册信息持久化到 PostgreSQL,并实现自动清理下线/失效的 agent。 + +## 当前状态 + +- ✅ Agent 通过共享 token 认证 +- ✅ Agent 自报 ID 并动态注册到内存 registry +- ❌ Agent 信息未持久化,服务重启后丢失 +- ❌ 没有自动清理下线 agent 的机制 + +## 数据库 Schema + +### 新增 `agents` 表 + +```sql +CREATE TABLE IF NOT EXISTS public.agents ( + id TEXT PRIMARY KEY, -- Agent ID (e.g., "hk-xhttp.svc.plus") + name TEXT NOT NULL DEFAULT '', -- Display name + groups TEXT[] NOT NULL DEFAULT '{}', -- Agent groups (e.g., {"internal"}) + healthy BOOLEAN NOT NULL DEFAULT false, -- Last reported health status + last_heartbeat TIMESTAMPTZ, -- Last successful heartbeat time + clients_count INTEGER NOT NULL DEFAULT 0, -- Number of Xray clients + sync_revision TEXT, -- Last sync revision + created_at TIMESTAMPTZ NOT NULL DEFAULT now(), + updated_at TIMESTAMPTZ NOT NULL DEFAULT now() +); + +CREATE INDEX IF NOT EXISTS idx_agents_last_heartbeat ON public.agents(last_heartbeat); +CREATE INDEX IF NOT EXISTS idx_agents_healthy ON public.agents(healthy); +``` + +### 迁移脚本 + +**文件**: `sql/20260205_agents_table.sql` + +```sql +-- Agent registration and health tracking +CREATE TABLE IF NOT EXISTS public.agents ( + id TEXT PRIMARY KEY, + name TEXT NOT NULL DEFAULT '', + groups TEXT[] NOT NULL DEFAULT '{}', + healthy BOOLEAN NOT NULL DEFAULT false, + last_heartbeat TIMESTAMPTZ, + clients_count INTEGER NOT NULL DEFAULT 0, + sync_revision TEXT, + created_at TIMESTAMPTZ NOT NULL DEFAULT now(), + updated_at TIMESTAMPTZ NOT NULL DEFAULT now() +); + +CREATE INDEX IF NOT EXISTS idx_agents_last_heartbeat ON public.agents(last_heartbeat); +CREATE INDEX IF NOT EXISTS idx_agents_healthy ON public.agents(healthy); + +COMMENT ON TABLE public.agents IS 'Registered agents with health tracking'; +COMMENT ON COLUMN public.agents.id IS 'Self-reported agent ID'; +COMMENT ON COLUMN public.agents.last_heartbeat IS 'Last successful heartbeat timestamp'; +``` + +## 代码修改 + +### 1.
