Types

type ExecMonitor added in v1.11.0 

type ExecMonitor interface {
	// MessageApplied is called after a message has been applied. Returning an error will halt execution of any further messages.
	MessageApplied(ctx context.Context, ts *types.TipSet, mcid cid.Cid, msg *types.Message, ret *vm.ApplyRet, implicit bool) error
}

type Executor added in v1.11.3 

type Executor interface {
	NewActorRegistry() *vm.ActorRegistry
	ExecuteTipSet(ctx context.Context, sm *StateManager, ts *types.TipSet, em ExecMonitor) (stateroot cid.Cid, rectsroot cid.Cid, err error)
}

type InvocationTracer added in v1.11.0 

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

func (*InvocationTracer) MessageApplied added in v1.11.0 

func (i *InvocationTracer) MessageApplied(ctx context.Context, ts *types.TipSet, mcid cid.Cid, msg *types.Message, ret *vm.ApplyRet, implicit bool) error

type MigrationCache added in v1.4.2 

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 v1.4.2 

type MigrationFunc func(
	ctx context.Context,
	sm *StateManager, cache MigrationCache,
	cb ExecMonitor, 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 first non-null tipset after the upgrade height (the tipset in which the upgrade is executed). Do not assume that ts.Height() is the upgrade height.

NOTE: In StateCompute and CallWithGas, the passed tipset is actually the tipset _before_ the upgrade. The tipset should really only be used for referencing the "current chain".

type PreMigration added in v1.4.2 

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 v1.4.2 

type PreMigrationFunc func(
	ctx context.Context,
	sm *StateManager, 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 StateManager 

type StateManager struct {
	Syscalls vm.SyscallBuilder
	// contains filtered or unexported fields
}

func NewStateManager 

func NewStateManager(cs *store.ChainStore, exec Executor, sys vm.SyscallBuilder, us UpgradeSchedule, beacon beacon.Schedule) (*StateManager, error)

func NewStateManagerWithUpgradeScheduleAndMonitor added in v1.11.0 

func NewStateManagerWithUpgradeScheduleAndMonitor(cs *store.ChainStore, exec Executor, sys vm.SyscallBuilder, us UpgradeSchedule, b beacon.Schedule, em ExecMonitor) (*StateManager, error)

func (*StateManager) Beacon added in v1.12.0 

func (sm *StateManager) Beacon() beacon.Schedule

func (*StateManager) Call 

func (sm *StateManager) Call(ctx context.Context, msg *types.Message, ts *types.TipSet) (*api.InvocResult, error)

Call applies the given message to the given tipset's parent state, at the epoch following the tipset's parent. In the presence of null blocks, the height at which the message is invoked may be less than the specified tipset.

  • If no tipset is specified, the first tipset without an expensive migration is used.
  • If executing a message at a given tipset would trigger an expensive migration, the call will fail with ErrExpensiveFork.
