Overview ¶

Package migrate is a small SQLite migration runner shared across hive's databases. It applies embedded, versioned up SQL migrations (NNNN_name.up.sql) tracked in a schema_migrations table, one transaction per migration.

It is deliberately storage-agnostic: callers pass an fs.FS rooted at their migration files (e.g. fs.Sub(embedFS, "migrations")), so each database owns its own migration set while sharing this runner. Any bootstrapping specific to a database (such as seeding from a legacy version table) is the caller's responsibility: load the migrations, EnsureTable, do the bootstrap, then Apply.

Functions ¶

func AppliedVersions ¶

func AppliedVersions(ctx context.Context, conn *sql.DB) (map[int]bool, error)

AppliedVersions returns the set of already-applied migration versions.

func Apply ¶

func Apply(ctx context.Context, conn *sql.DB, migrations []Migration) error

Apply ensures the tracking table exists, then applies every migration not already recorded, in ascending version order, one transaction each.

func EnsureTable ¶

func EnsureTable(ctx context.Context, conn *sql.DB) error

EnsureTable creates the schema_migrations tracking table if it does not exist.

func Up ¶

func Up(ctx context.Context, conn *sql.DB, fsys fs.FS) error

Up loads the migrations from fsys and applies all pending ones in version order. It does not perform any legacy bootstrapping; callers needing that should Load + EnsureTable + bootstrap + Apply instead.

Types ¶

type Migration ¶

type Migration struct {
	Version int
	Name    string
	UpSQL   string
}

Migration is a single versioned migration with its up SQL.

func Load ¶

func Load(fsys fs.FS) ([]Migration, error)

Load parses NNNN_name.up.sql files from the root of fsys into a version-sorted slice. It validates the naming format and rejects duplicate versions.
