	// checks stage.
	CommitApplies()

	// Finish closes this test vector (transioning it to the terminal finished
	// stage), and returns it.
	Finish() *schema.TestVector
}

Builder is a vector builder.

It enforces a staged process for constructing a vector, starting in a "preconditions" stage, where the state tree is manipulated into the desired shape for the test to begin.

Next, the "applies" stage serves as a time to accumulate messages that will mutate the state.

Transitioning to the "checks" stage applies the messages and transitions the builder to a period where any final assertions can be made on the receipts or the state of the system.

Finally, transitioning to the "finished" stage finalizes the test vector, serializing the pre and post state trees and completing the stages.

From here the test vector can be serialized into a JSON file.

type BuilderCommon 

type BuilderCommon struct {
	Stage  Stage
	Actors *Actors
	Assert *Asserter

	OutputPath    string
	Mode          OverwriteMode
	IncludeFilter *regexp.Regexp
	// contains filtered or unexported fields
}

Generator is a batch generator and organizer of test vectors.

Test vector scripts are simple programs (main function). Test vector scripts can delegate to the Generator to handle the execution, reporting and capture of emitted test vectors into files.

Generator supports the following CLI flags: 

 -o <directory>
		directory where test vector JSON files will be saved; if omitted,
		vectors will be written to stdout.

 -u
		update any existing test vector files in the output directory IF their
		content has changed. Note `_meta` is ignored when checking equality.

 -f
		force regeneration and overwrite any existing vectors in the output
		directory.

 -i <include regex>
		regex inclusion filter to select a subset of vectors to execute; matched
		against the vector's ID.

 TODO
 -v <protocol versions, comma-separated>
     protocol version variants to generate; if not provided, all supported
     protocol versions as declared by the vector will be attempted

Scripts can bundle test vectors into "groups". The generator will execute each group in parallel, and will write each vector in a file: <output_dir>/<group>--<vector_id>.json

}

MessageVectorBuilder is a helper for building a message-class test vector. It enforces a staged process for constructing a vector, starting in a "preconditions" stage, where the state tree is manipulated into the desired shape for the test to begin. Next, the "applies" stage serves as a time to accumulate messages that will mutate the state. Transitioning to the "checks" stage applies the messages and transitions the builder to a period where any final assertions can be made on the receipts or the state of the system. Finally, transitioning to the "finished" stage finalizes the test vector, serializing the pre and post state trees and completing the stages. From here the test vector can be serialized into a JSON file.

CommitApplies applies all accumulated messages. For each message it records the new state root, refreshes the state tree, and updates the underlying vector with the message and its receipt.

This method progresses the builder into the "checks" stage and may only be called during the "applies" stage.

func (*MessageVectorBuilder) CommitPreconditions 

func (b *MessageVectorBuilder) CommitPreconditions()

CommitPreconditions flushes the state tree, recording the new CID in the underlying test vector's precondition.

This method progesses the builder into the "applies" stage and may only be called during the "preconditions" stage.

func (*MessageVectorBuilder) Finish 

func (b *MessageVectorBuilder) Finish() *schema.TestVector

Finish signals to the builder that the checks stage is complete and that the test vector can be finalized. It creates a CAR from the recorded state root in it's pre and post condition and serializes the CAR into the test vector.

This method progresses the builder into the "finished" stage and may only be called during the "checks" stage.

	schema.Tipset
	// contains filtered or unexported fields
}

func (*Tipset) Block

type TipsetSeq 

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

TipsetSeq is a sequence of tipsets to be applied during the test. TipsetSeq provides methods to build a sequence of tipsets, such as adding new tipsets and null rounds.

func NewTipsetSeq 

func NewTipsetSeq(initialEpoch abi.ChainEpoch) *TipsetSeq

NewTipsetSeq returns a new TipSetSeq object initialized at the provided epoch.

func (*TipsetSeq) All 

func (tss *TipsetSeq) All() []*Tipset

type TipsetVectorBuilder 

type TipsetVectorBuilder struct {
	*BuilderCommon

	// StagedMessages is a staging area for messages.
	StagedMessages *Messages
	// StateTracker is used for staging messages, and it's scrapped and replaced
	// by a fork at the PreRoot when committing applies.
	StateTracker *StateTracker

	InitialEpochOffset abi.ChainEpoch

	Tipsets *TipsetSeq
	Rewards *Rewards

	PreRoot  cid.Cid
	PostRoot cid.Cid
	// contains filtered or unexported fields
}

TipsetVectorBuilder builds a tipset-class vector. It follows the same staged approach as MessageVectorBuilder.

During the precondition stage, the user sets up the pre-existing state of the system, including the miners that are going to be producing the blocks comprising the vector. If the initial epoch is different to 0, the user must also set it during the precondition stage via SetInitialEpochOffset.

During the application stage, the user stages the messages they later want to incorporate to a block in the StagedMessages object. Messages applied have no effect on the vector itself. The entire state is scrapped.

Tipsets are registered in the Tipsets object, by calling Tipset#Next. This "opens" a new tipset at the next epoch, starting at the initial epoch set by SetInitialEpochOffset, and internally incrementing the counter by one.

To register blocks on a tipset, call Tipset#Block, supplying the miner, win count, and the messages to enroll. Messages need to have been staged previously.

func TipsetVector 

func TipsetVector(metadata *schema.Metadata, selector schema.Selector, mode Mode, hints []string, pv ProtocolVersion) *TipsetVectorBuilder

TipsetVector creates a new TipsetVectorBuilder. For usage details, read the godocs on that type.

func (*TipsetVectorBuilder) CommitApplies 

func (b *TipsetVectorBuilder) CommitApplies()

CommitApplies applies all accumulated tipsets. It updates the vector after every tipset application, and records the Rewards state existing at that epoch under the Rewards object.

It also sets the PostStateRoot on each applied Tipset, which can be used in combination with StateTracker#Fork and Asserter#AtState to load and assert on state at an interim tipset.

This method progresses the builder into the "checks" stage and may only be called during the "applies" stage.

func (*TipsetVectorBuilder) CommitPreconditions 

func (b *TipsetVectorBuilder) CommitPreconditions()

CommitPreconditions flushes the state tree, recording the new CID in the underlying test vector's precondition. It creates the StagedMessages and Tipsets object where messages will be staged, and tipsets will be registered.

This method progesses the builder into the "applies" stage and may only be called during the "preconditions" stage.

func (*TipsetVectorBuilder) Finish 

func (b *TipsetVectorBuilder) Finish() *schema.TestVector

Finish signals to the builder that the checks stage is complete and that the test vector can be finalized. It writes the test vector to the supplied io.Writer.

This method progresses the builder into the "finished" stage and may only be called during the "checks" stage.

func (*TipsetVectorBuilder) SetInitialEpochOffset 

func (b *TipsetVectorBuilder) SetInitialEpochOffset(epoch abi.ChainEpoch)

SetInitialEpochOffset sets the initial epoch offset of this tipset-class vector. It MUST be called during the preconditions stage.
