Types ¶
type InfrastructureData ¶
type InfrastructureData struct {
// Provider is the name of infrastructure provider backing the testnet.
// For example, 'docker' if it is running locally in a docker network or
// 'digital-ocean', 'aws', 'google', etc. if it is from a cloud provider.
Provider string `json:"provider"`
// Instances is a map of all of the machine instances on which to run
// processes for a testnet.
// The key of the map is the name of the instance, which each must correspond
// to the names of one of the testnet nodes defined in the testnet manifest.
Instances map[string]InstanceData `json:"instances"`
// Network is the CIDR notation range of IP addresses that all of the instances'
// IP addresses are expected to be within.
Network string `json:"network"`
}
InfrastructureData contains the relevant information for a set of existing infrastructure that is to be used for running a testnet.
func InfrastructureDataFromFile ¶
func InfrastructureDataFromFile(p string) (InfrastructureData, error)
func NewDockerInfrastructureData ¶
func NewDockerInfrastructureData(m Manifest) (InfrastructureData, error)
type InstanceData ¶
InstanceData contains the relevant information for a machine instance backing one of the nodes in the testnet.
type Manifest ¶
type Manifest struct {
// IPv6 uses IPv6 networking instead of IPv4. Defaults to IPv4.
IPv6 bool `toml:"ipv6"`
// InitialHeight specifies the initial block height, set in genesis. Defaults to 1.
InitialHeight int64 `toml:"initial_height"`
// InitialState is an initial set of key/value pairs for the application,
// set in genesis. Defaults to nothing.
InitialState map[string]string `toml:"initial_state"`
// Validators is the initial validator set in genesis, given as node names
// and power:
//
// validators = { validator01 = 10; validator02 = 20; validator03 = 30 }
//
// Defaults to all nodes that have mode=validator at power 100. Explicitly
// specifying an empty set will start with no validators in genesis, and
// the application must return the validator set in InitChain via the
// setting validator_update.0 (see below).
Validators *map[string]int64 `toml:"validators"`
// ValidatorUpdates is a map of heights to validator names and their power,
// and will be returned by the ABCI application. For example, the following
// changes the power of validator01 and validator02 at height 1000:
//
// [validator_update.1000]
// validator01 = 20
// validator02 = 10
//
// Specifying height 0 returns the validator update during InitChain. The
// application returns the validator updates as-is, i.e. removing a
// validator must be done by returning it with power 0, and any validators
// not specified are not changed.
ValidatorUpdates map[string]map[string]int64 `toml:"validator_update"`
// Nodes specifies the network nodes. At least one node must be given.
Nodes map[string]*ManifestNode `toml:"node"`

// Options are ed25519 & secp256k1
KeyType string `toml:"key_type"`
// Evidence indicates the amount of evidence that will be injected into the
// testnet via the RPC endpoint of a random node. Default is 0
Evidence int `toml:"evidence"`
// ABCIProtocol specifies the protocol used to communicate with the ABCI
// application: "unix", "tcp", "grpc", or "builtin". Defaults to builtin.
// builtin will build a complete CometBFT node into the application and
// launch it instead of launching a separate CometBFT process.
ABCIProtocol string `toml:"abci_protocol"`

CheckTxDelay time.Duration `toml:"check_tx_delay"`
// UpgradeVersion specifies to which version nodes need to upgrade.
// Currently only uncoordinated upgrade is supported
UpgradeVersion string `toml:"upgrade_version"`
LoadTxSizeBytes int `toml:"load_tx_size_bytes"`

func LoadManifest ¶
LoadManifest loads a testnet manifest from a file.
type ManifestNode ¶
type ManifestNode struct {
// Mode specifies the type of node: "validator", "full", "light" or "seed".
// Defaults to "validator". Full nodes do not get a signing key (a dummy key
// is generated), and seed nodes run in seed mode with the PEX reactor enabled.
Mode string `toml:"mode"`
// Version specifies which version of CometBFT this node is. Specifying different
// versions for different nodes allows for testing the interaction of different
// node's compatibility. Note that in order to use a node at a particular version,
// there must be a docker image of the test app tagged with this version present
// on the machine where the test is being run.
Version string `toml:"version"`
// Seeds is the list of node names to use as P2P seed nodes. Defaults to none.
Seeds []string `toml:"seeds"`
// PersistentPeers is a list of node names to maintain persistent P2P
// connections to. If neither seeds nor persistent peers are specified,
// this defaults to all other nodes in the network. For light clients,
// this relates to the providers the light client is connected to.
PersistentPeers []string `toml:"persistent_peers"`
// Database specifies the database backend: "goleveldb", "cleveldb",
// "rocksdb", "boltdb", or "badgerdb". Defaults to goleveldb.
Database string `toml:"database"`
// PrivvalProtocol specifies the protocol used to sign consensus messages:
// "file", "unix", or "tcp". Defaults to "file". For unix and tcp, the ABCI
// application will launch a remote signer client in a separate goroutine.
// Only nodes with mode=validator will actually make use of this.
PrivvalProtocol string `toml:"privval_protocol"`
// StartAt specifies the block height at which the node will be started. The
// runner will wait for the network to reach at least this block height.
StartAt int64 `toml:"start_at"`
// BlockSync specifies the block sync mode: "" (disable), "v0" or "v2".
// Defaults to disabled.
//
// Note that BlockSync will always be enabled in the next major release and the
// `block_sync` key will be removed from the config file.
BlockSync string `toml:"block_sync"`
// Mempool specifies which version of mempool to use. Either "v0" or "v1"
// This defaults to v0.
Mempool string `toml:"mempool_version"`
// StateSync enables state sync. The runner automatically configures trusted
// block hashes and RPC servers. At least one node in the network must have
// SnapshotInterval set to non-zero, and the state syncing node must have
// StartAt set to an appropriate height where a snapshot is available.
StateSync bool `toml:"state_sync"`
// PersistInterval specifies the height interval at which the application
// will persist state to disk. Defaults to 1 (every height), setting this to
// 0 disables state persistence.
PersistInterval *uint64 `toml:"persist_interval"`
// SnapshotInterval specifies the height interval at which the application
// will take state sync snapshots. Defaults to 0 (disabled).
SnapshotInterval uint64 `toml:"snapshot_interval"`
// RetainBlocks specifies the number of recent blocks to retain. Defaults to
// 0, which retains all blocks. Must be greater that PersistInterval and
// SnapshotInterval.
RetainBlocks uint64 `toml:"retain_blocks"`
// Perturb lists perturbations to apply to the node after it has been
// started and synced with the network:
//
// disconnect: temporarily disconnects the node from the network
// kill: kills the node with SIGKILL then restarts it
// pause: temporarily pauses (freezes) the node
// restart: restarts the node, shutting it down with SIGTERM
Perturb []string `toml:"perturb"`
// SendNoLoad determines if the e2e test should send load to this node.
// It defaults to false so unless the configured, the node will
// receive load.
SendNoLoad bool `toml:"send_no_load"`
}
ManifestNode represents a node in a testnet manifest.

func LoadTestnet ¶
func LoadTestnet(manifest Manifest, fname string, ifd InfrastructureData) (*Testnet, error)
LoadTestnet loads a testnet from a manifest file, using the filename to determine the testnet name and directory (from the basename of the file). The testnet generation must be deterministic, since it is generated separately by the runner and the test cases. For this reason, testnets use a random seed to generate e.g. keys.
func (Testnet) ArchiveNodes ¶
ArchiveNodes returns a list of archive nodes that start at the initial height and contain the entire blockchain history. They are used e.g. as light client RPC servers.
func (Testnet) HasPerturbations ¶
HasPerturbations returns whether the network has any perturbations.
func (Testnet) LookupNode ¶
LookupNode looks up a node by name. For now, simply do a linear search.
func (Testnet) RandomNode ¶
RandomNode returns a random non-seed node.
