type Migration added in v1.10.0 

type Migration struct {
	// contains filtered or unexported fields
}

type MigrationCache added in v0.9.1 

type MigrationCache interface {
	Write(key string, value cid.Cid) error
	Read(key string) (bool, cid.Cid, error)
	Load(key string, loadFunc func() (cid.Cid, error)) (cid.Cid, error)
}

MigrationCache can be used to cache information used by a migration. This is primarily useful to "pre-compute" some migration state ahead of time, and make it accessible in the migration itself.

type MigrationFunc added in v0.9.1 

type MigrationFunc func(
	ctx context.Context,
	cache MigrationCache,
	oldState cid.Cid,
	height abi.ChainEpoch,
	ts *types.TipSet,
) (newState cid.Cid, err error)

MigrationFunc is a migration function run at every upgrade.

  • The cache is a per-upgrade cache, pre-populated by pre-migrations.
  • The oldState is the state produced by the upgrade epoch.
  • The returned newState is the new state that will be used by the next epoch.
  • The height is the upgrade epoch height (already executed).
  • The tipset is the tipset for the last non-null block before the upgrade. Do not assume that ts.Height() is the upgrade height.

type PreMigration added in v0.9.1 

type PreMigration struct {
	// PreMigration is the pre-migration function to run at the specified time. This function is
	// run asynchronously and must abort promptly when canceled.
	PreMigration PreMigrationFunc

	// StartWithin specifies that this pre-migration should be started at most StartWithin
	// epochs before the upgrade.
	StartWithin abi.ChainEpoch

	// DontStartWithin specifies that this pre-migration should not be started DontStartWithin
	// epochs before the final upgrade epoch.
	//
	// This should be set such that the pre-migration is likely to complete before StopWithin.
	DontStartWithin abi.ChainEpoch

	// StopWithin specifies that this pre-migration should be stopped StopWithin epochs of the
	// final upgrade epoch.
	StopWithin abi.ChainEpoch
}

PreMigration describes a pre-migration step to prepare for a network state upgrade. Pre-migrations are optimizations, are not guaranteed to run, and may be canceled and/or run multiple times.

type PreMigrationFunc added in v0.9.1 

type PreMigrationFunc func(
	ctx context.Context,
	cache MigrationCache,
	oldState cid.Cid,
	height abi.ChainEpoch,
	ts *types.TipSet,
) error

PreMigrationFunc is a function run _before_ a network upgrade to pre-compute part of the network upgrade and speed it up.

type Upgrade 

type Upgrade struct {
	Height    abi.ChainEpoch
	Network   network.Version
	Expensive bool
	Migration MigrationFunc

	// PreMigrations specifies a set of pre-migration functions to run at the indicated epochs.
	// These functions should fill the given cache with information that can speed up the
	// eventual full migration at the upgrade epoch.
	PreMigrations []PreMigration
}

type UpgradeSchedule 

type UpgradeSchedule []Upgrade

func DefaultUpgradeSchedule added in v1.2.0 

func DefaultUpgradeSchedule(cf *ChainFork, upgradeHeight *config.ForkUpgradeConfig) UpgradeSchedule

func (UpgradeSchedule) Validate
