These are globals that describe network upgrades and node versions

var GitCommit string

GitCommit is set in the build script at compile time

Types

type Application

type Application struct {
	Name  string `json:"name"  yaml:"name"`
	Major int    `json:"major" yaml:"major"`
	Minor int    `json:"minor" yaml:"minor"`
	Patch int    `json:"patch" yaml:"patch"`
	// contains filtered or unexported fields
}

func (*Application) Before

func (a *Application) Before(o *Application) bool

func (*Application) Compare

func (a *Application) Compare(o *Application) int

Compare returns a positive number if s > o, 0 if s == o, or a negative number if s < o.

func (*Application) Compatible

func (a *Application) Compatible(o *Application) error

func (*Application) String

func (a *Application) String() string

The only difference here between Application and Semantic is that Application prepends the client name rather than "v".

type Compatibility

type Compatibility interface {
	// Returns the local version
	Version() *Application

	// Returns nil if the provided version is compatible with the local version.
	// This means that the version is connectable and that consensus messages
	// can be made to them.
	Compatible(*Application) error
}

Compatibility a utility for checking the compatibility of peer versions

func GetCompatibility

func GetCompatibility(minCompatibleTime time.Time) Compatibility

func NewCompatibility

func NewCompatibility(
	version *Application,
	minCompatible *Application,
	minCompatibleTime time.Time,
	prevMinCompatible *Application,
) Compatibility

NewCompatibility returns a compatibility checker with the provided options

type Semantic

type Semantic struct {
	Major int `json:"major" yaml:"major"`
	Minor int `json:"minor" yaml:"minor"`
	Patch int `json:"patch" yaml:"patch"`
	// contains filtered or unexported fields
}

func Parse

func Parse(s string) (*Semantic, error)

func (*Semantic) Compare

func (s *Semantic) Compare(o *Semantic) int

Compare returns a positive number if s > o, 0 if s == o, or a negative number if s < o.

func (*Semantic) String

func (s *Semantic) String() string

The only difference here between Semantic and Application is that Semantic prepends "v" rather than the client name.

type Versions

type Versions struct {
	Application string `json:"application"`
	Database    string `json:"database"`
	RPCChainVM  uint64 `json:"rpcchainvm"`
	// Commit may be empty if GitCommit was not set at compile time
	Commit string `json:"commit"`
	Go     string `json:"go"`
}

Versions contains the versions relevant to a build of avalanchego. In addition to supporting construction of the string displayed by --version, it is used to produce the output of --version-json and can be used to unmarshal that output.

func GetVersions

func GetVersions() *Versions

func (*Versions) String

func (v *Versions) String() string
