func MaskDBCred

func MaskDBCred(str string) string

MaskDBCred hides DB credentials in connection string

func UpdateDBLevel

func UpdateDBLevel(db *DB, levels *Levels) error

UpdateDBLevel updates the levels for the tables in the database

func UpdateSchema

func UpdateSchema(db *DB, levels *Levels) error

Types

type DB

type DB struct {
	*sqlx.DB
	// Indicates if database was successfully initialized
	IsDBInitialized bool
}

DB is an adapter for sqlx.DB and implements FabricCADB interface

func NewUserRegistryMySQL

func NewUserRegistryMySQL(datasource string, clientTLSConfig *tls.ClientTLSConfig, csp bccsp.BCCSP) (*DB, error)

NewUserRegistryMySQL opens a connection to a postgres database

func NewUserRegistryPostgres

func NewUserRegistryPostgres(datasource string, clientTLSConfig *tls.ClientTLSConfig) (*DB, error)

NewUserRegistryPostgres opens a connection to a postgres database

func NewUserRegistrySQLLite3

func NewUserRegistrySQLLite3(datasource string) (*DB, error)

NewUserRegistrySQLLite3 returns a pointer to a sqlite database

func (*DB) BeginTx

func (db *DB) BeginTx() FabricCATx

BeginTx implements BeginTx method of FabricCADB interface

func (*DB) IsInitialized

func (db *DB) IsInitialized() bool

IsInitialized returns true if db is intialized, else false

type FabricCADB

type FabricCADB interface {
	IsInitialized() bool
	Select(dest interface{}, query string, args ...interface{}) error
	Exec(query string, args ...interface{}) (sql.Result, error)
	NamedExec(query string, arg interface{}) (sql.Result, error)
	Rebind(query string) string
	MustBegin() *sqlx.Tx
	// BeginTx has same behavior as MustBegin except it returns FabricCATx
	// instead of *sqlx.Tx
	BeginTx() FabricCATx
}

FabricCADB is the interface with functions implemented by sqlx.DB object that are used by Fabric CA server

type FabricCATx

type FabricCATx interface {
	Select(dest interface{}, query string, args ...interface{}) error
	Rebind(query string) string
	Exec(query string, args ...interface{}) (sql.Result, error)
	Commit() error
	Rollback() error
}

FabricCATx is the interface with functions implemented by sqlx.Tx object that are used by Fabric CA server

type Levels

type Levels struct {
	Identity    int
	Affiliation int
	Certificate int
	Credential  int
	RAInfo      int
	Nonce       int
}

Levels contains the levels of identities, affiliations, and certificates
