Functions

func ValidateChannelID

func ValidateChannelID(channelID string) error

ValidateChannelID makes sure that proposed channel IDs comply with the following restrictions:

1. Contain only lower case ASCII alphanumerics, dots '.', and dashes '-'
2. Are shorter than 250 characters.
3. Start with a letter

This is the intersection of the Kafka restrictions and CouchDB restrictions with the following exception: '.' is converted to '_' in the CouchDB naming This is to accommodate existing channel names with '.', especially in the behave tests which rely on the dot notation for their sluggification.

note: this function is a copy of the same in common/configtx/validator.go

EndorserTx represents a parsed common.Envelope protobuf

func UnmarshalEndorserTxAndValidate

func UnmarshalEndorserTxAndValidate(txenv *tx.Envelope) (*EndorserTx, error)

UnmarshalEndorserTxAndValidate receives a tx.Envelope containing a partially unmarshalled endorser transaction and returns an EndorserTx instance (or an error)
