Functions

func ConfigForkVersions 

func ConfigForkVersions(b *BeaconChainConfig) map[[fieldparams.VersionLength]byte]int

ConfigForkVersions returns a mapping between a fork version param and the version identifier from the runtime/version package.

func ConfigToYaml 

func ConfigToYaml(cfg *BeaconChainConfig) []byte

ConfigToYaml takes a provided config and outputs its contents in yaml. This allows prysm's custom configs to be read by other clients.

func DenebEnabled 

func DenebEnabled() bool

DenebEnabled centralizes the check to determine if code paths that are specific to deneb should be allowed to execute. This will make it easier to find call sites that do this kind of check and remove them post-deneb.

func FillTestVersions 

func FillTestVersions(c *BeaconChainConfig, b byte)

FillTestVersions replaces the fork schedule in the given BeaconChainConfig with test values, using the given byte argument as the high byte (common across forks).

func LoadChainConfigFile 

func LoadChainConfigFile(path string, conf *BeaconChainConfig) error

LoadChainConfigFile load, convert hex values into valid param yaml format, unmarshal , and apply beacon chain config file.

func MaxRequestBlock 

func MaxRequestBlock(e primitives.Epoch) uint64

MaxRequestBlock determines the maximum number of blocks that can be requested in a single request for a given epoch. If the epoch is at or beyond config's `DenebForkEpoch`, a special limit defined for Deneb is used.

func OverrideBeaconConfig 

func OverrideBeaconConfig(c *BeaconChainConfig)

OverrideBeaconConfig by replacing the config. The preferred pattern is to call BeaconConfig(), change the specific parameters, and then call OverrideBeaconConfig(c). Any subsequent calls to params.BeaconConfig() will return this new configuration.

func OverrideBeaconNetworkConfig 

func OverrideBeaconNetworkConfig(cfg *NetworkConfig)

OverrideBeaconNetworkConfig will override the network config with the added argument.

func ReplaceHexStringWithYAMLFormat 

func ReplaceHexStringWithYAMLFormat(line string) []string

ReplaceHexStringWithYAMLFormat will replace hex strings that the yaml parser will understand.

func SetActive 

func SetActive(c *BeaconChainConfig) error

SetActive sets the given config as active (the config that will be returned by GetActive). SetActive will always overwrite any config with the same ConfigName before setting the updated value to active.

func SetActiveTestCleanup 

func SetActiveTestCleanup(t *testing.T, cfg *BeaconChainConfig)

SetActiveTestCleanup sets an active config, and adds a test cleanup hook to revert to the default config after the test completes.

func SetActiveWithUndo 

func SetActiveWithUndo(c *BeaconChainConfig) (func() error, error)

SetActiveWithUndo attempts to set the active config, and if successful, returns a callback function that can be used to revert the configset back to its previous state.

func SetupTestConfigCleanup 

func SetupTestConfigCleanup(t testing.TB)

SetupTestConfigCleanup preserves configurations allowing to modify them within tests without any restrictions, everything is restored after the test.

func UseHoleskyNetworkConfig 

func UseHoleskyNetworkConfig()

UseHoleskyNetworkConfig uses the Holesky beacon chain specific network config.

func UseSepoliaNetworkConfig 

func UseSepoliaNetworkConfig()

UseSepoliaNetworkConfig uses the Sepolia beacon chain specific network config.

func WithinDAPeriod 

func WithinDAPeriod(block, current primitives.Epoch) bool

WithinDAPeriod checks if the block epoch is within MIN_EPOCHS_FOR_BLOB_SIDECARS_REQUESTS of the given current epoch.
