title: "migrations: prevent accidentally using inner unversioned migration instead of `VersionedMigration`"
|
|
|
|
doc:
|
|
- audience: Runtime Dev
|
|
description: |
|
|
Currently, it is possible to accidentally use inner unversioned migration instead of `VersionedMigration`
|
|
since both implement `OnRuntimeUpgrade`. With this change, we make it clear that `Inner` is not intended
|
|
to be used directly. It is achieved by bounding `Inner` to new trait `UncheckedOnRuntimeUpgrade`, which
|
|
has the same interface as `OnRuntimeUpgrade`, but can not be used directly for runtime upgrade migrations.
|
|
|
|
This change will break all existing migrations passed to `VersionedMigration`. Developers should simply change
|
|
those migrations to implement `UncheckedOnRuntimeUpgrade` instead of `OnRuntimeUpgrade`.
|
|
|

|
|
|
|
