Types ¶
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"`
// KeyType sets the curve that will be used by validators.
// Options are ed25519 & secp256k1
KeyType string `toml:"key_type"`
}
Manifest represents a TOML testnet manifest.
func LoadManifest ¶
LoadManifest loads a testnet manifest from a file.
type ManifestNode ¶
type ManifestNode struct {
// Mode specifies the type of node: "validator", "full", 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"`
// 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.
PersistentPeers []string `toml:"persistent_peers"`
// Database specifies the database backend: "goleveldb", "cleveldb",
// "rocksdb", "boltdb", or "badgerdb". Defaults to goleveldb.
Database string `toml:"database"`
// ABCIProtocol specifies the protocol used to communicate with the ABCI
// application: "unix", "tcp", "grpc", or "builtin". Defaults to unix.
// builtin will build a complete Tendermint node into the application and
// launch it instead of launching a separate Tendermint process.
ABCIProtocol string `toml:"abci_protocol"`
// 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"`
// FastSync specifies the fast sync mode: "" (disable), "v0", "v1", or "v2".
// Defaults to disabled.
FastSync string `toml:"fast_sync"`
// 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"`
// Misbehaviors sets how a validator behaves during consensus at a
// certain height. Multiple misbehaviors at different heights can be used
//
// An example of misbehaviors
// { 10 = "double-prevote", 20 = "double-prevote"}
//
// For more information, look at the readme in the maverick folder.
// A list of all behaviors can be found in ../maverick/consensus/behavior.go
Misbehaviors map[string]string `toml:"misbehaviors"`
}
ManifestNode represents a node in a testnet manifest.
type Node ¶
type Node struct {
Name string
Testnet *Testnet
Mode Mode
PrivvalKey crypto.PrivKey
NodeKey crypto.PrivKey
IP net.IP
ProxyPort uint32
StartAt int64
FastSync string
StateSync bool
Database string
ABCIProtocol Protocol
PrivvalProtocol Protocol
PersistInterval uint64
SnapshotInterval uint64
RetainBlocks uint64
Seeds []*Node
PersistentPeers []*Node
Perturbations []Perturbation
Misbehaviors map[int64]string
}
Node represents a Tendermint node in a testnet.
func (Node) AddressP2P ¶
Address returns a P2P endpoint address for the node.
func (Node) AddressRPC ¶
Address returns an RPC endpoint address for the node.
type Perturbation ¶
type Perturbation string
type Testnet ¶
type Testnet struct {
Name string
File string
Dir string
IP *net.IPNet
InitialHeight int64
InitialState map[string]string
Validators map[*Node]int64
ValidatorUpdates map[int64]map[*Node]int64
Nodes []*Node
KeyType string
}
Testnet represents a single testnet.
func LoadTestnet ¶
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) LastMisbehaviorHeight ¶
LastMisbehaviorHeight returns the height of the last misbehavior.
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.
