分析失败: %v

Error message

分析失败: %v

What it means

The gva_analyze MCP tool's Handle wraps any failure from performAnalysis (server/mcp/gva_analyze.go:87) with the generic prefix "分析失败: %v". It means the analyzer could not produce the snapshot of existing packages/modules/dictionaries. The underlying cause is always one of the wrapped sub-errors (获取包信息失败, 获取历史记录失败, etc.), so read the suffix for the real problem.

Solutions

  1. Read the suffix after "分析失败:" — it names the failing step (包信息/历史记录) and the root error.
  2. Verify the GVA server and its database are running and the sys_auto_code_* tables exist.
  3. Ensure the request context carries valid auth (the fetches use the caller's token from ctx).
  4. Check config.yaml AutoCode.root/server paths are set before invoking the tool.
  5. Retry the gva_analyze call once the underlying dependency is healthy.

Example fix

// before: analyzing while DB is down -> 分析失败: 获取包信息失败: dial tcp ... refused
// after: start the backend/DB first, then call
gva_analyze({"requirement": "需要用户管理模块"})
Defensive patterns

Strategy: try-catch

Validate before calling

// MCP client: check backend health before calling the tool
const healthy = await fetch(`${baseUrl}/health`).then(r => r.ok).catch(() => false)
if (!healthy) throw new Error('GVA backend unavailable; skip gva_analyze')

Try / catch

try {
  const snapshot = await callTool('gva_analyze', { requirement })
} catch (e) {
  if (String(e.message).includes('分析失败')) {
    // surface the suffix cause: 获取包信息失败 / 获取历史记录失败
    console.error('analyze failed:', e.message)
  }
}

Prevention

When it happens

Trigger: An MCP client calls the gva_analyze tool while performAnalysis returns an error — typically fetchAutoCodePackages or fetchAutoCodeHistories failing (DB unavailable, auth/token missing from ctx, upstream API error).

Common situations: Calling gva_analyze when the GVA backend database is down or migrated incompletely; MCP server lacking valid credentials so auto-code package/history fetches fail; AutoCode configuration (autocode root path) not set so scans fail earlier in the chain.
