Enum frame_support::migrations::FailedMigrationHandling

pub enum FailedMigrationHandling {
    ForceUnstuck,
    KeepStuck,
    Ignore,
}

How to proceed after a runtime upgrade failed.

There is NO SANE DEFAULT HERE. All options are very dangerous and should be used with care.

Variants

ForceUnstuck

Resume extrinsic processing of the chain. This will not resume the upgrade.

This should be supplemented with additional measures to ensure that the broken chain state does not get further messed up by user extrinsics.

KeepStuck

Set the cursor to Stuck and keep blocking extrinsics.

Ignore

Don’t do anything with the cursor and let the handler decide.

This can be useful in cases where the other two options would overwrite any changes that were done by the handler to the cursor.
