- config 增 DB_DRIVER(mysql 默认 | sqlite);DSN 对 sqlite 为文件路径
- db.OpenDriver 按驱动分派:sqlite 用 modernc(纯 Go 免 CGO)+ WAL/
busy_timeout/foreign_keys/_txlock=immediate;mysql 路径不变
- store.Open 分派;mysql 保留 UTC/collation 断言,sqlite 跳过
- 迁移拆 migrations/{mysql,sqlite}/ 双套,embed 双 FS,migrate 按驱动选源
与 golang-migrate 驱动;修复 m.Close() 误关调用方 *sql.DB 的坑
- cmd/migrate 串入 DB_DRIVER;集成测试 MigrateUp 签名更新
- 新增 SQLite 时间往返 smoke 测试与端到端迁移测试(免 docker)

// Command migrate applies or reverts database schema migrations for the
|
||
// Pangolin server.
|
||
//
|
||
// Usage:
|
||
//
|
||
// migrate up – apply all pending migrations
|
||
// migrate down – revert all applied migrations
|
||
// migrate version – print the current migration version
|
||
//
|
||
// Configuration is read from the DB_DSN environment variable (a full MySQL
|
||
// DSN), consistent with the rest of the server.
