Functions ¶
Types ¶
type File ¶
File contains one parsed immutable migration and its filesystem identity.
func Create ¶
Create atomically creates one migration artifact and never overwrites an existing filename.
func RequireCurrentHistory ¶
RequireCurrentHistory proves that a deployable executable manifest is the exact head of a non-empty, immutable artifact history. An empty history is a valid input only to migration creation; release checks and database commands must fail closed until the initial artifact has been created and committed.
func RequireCurrentHistoryForPlanner ¶
func RequireCurrentHistoryForPlanner(directory string, executable schema.Manifest, plannerName string) ([]File, error)
RequireCurrentHistoryForPlanner additionally proves that every immutable artifact belongs to the planner family selected by the project database. Adapter runners retain ownership of planner-version and exact-plan checks.
