Functions

func NewPrivilegedDatabase 

func NewPrivilegedDatabase(grantTables *MySQLDb, db sql.Database) sql.Database

NewPrivilegedDatabase returns a new PrivilegedDatabase.

func NewPrivilegedDatabaseProvider 

func NewPrivilegedDatabaseProvider(grantTables *MySQLDb, p sql.DatabaseProvider) sql.DatabaseProvider

func (db *MySQLDb) AddRootAccount()

AddRootAccount adds the root account to the list of accounts.

func (*MySQLDb) AddSuperUser 

func (db *MySQLDb) AddSuperUser(ed *Editor, username string, host string, password string)

func (db *MySQLDb) AuthMethod(user, addr string) (string, error)

AuthMethod implements the interface mysql.AuthServer.

func (*MySQLDb) Editor added in v0.17.0

func (db *MySQLDb) GetTableNames(ctx *sql.Context) ([]string, error)

GetTableNames implements the interface sql.Database.

func (*MySQLDb) GetUser 

func (db *MySQLDb) GetUser(fetcher UserFetcher, user string, host string, roleSearch bool) *User

GetUser returns a user matching the given user and host if it exists. Due to the slight difference between users and roles, roleSearch changes whether the search matches against user or role rules.

func (*MySQLDb) LoadData 

func (db *MySQLDb) LoadData(ctx *sql.Context, buf []byte) (err error)

LoadData adds the given data to the MySQL Tables. It does not remove any current data, but will overwrite any pre-existing data.

func (*MySQLDb) LoadPrivilegeData 

func (db *MySQLDb) LoadPrivilegeData(ctx *sql.Context, users []*User, roleConnections []*RoleEdge) error

LoadPrivilegeData adds the given data to the MySQL Tables. It does not remove any current data, but will overwrite any pre-existing data. This has been deprecated in favor of LoadData.

func (*MySQLDb) OverwriteUsersAndGrantData added in v0.17.0 

func (db *MySQLDb) OverwriteUsersAndGrantData(ctx *sql.Context, ed *Editor, buf []byte) (err error)

OverwriteUsersAndGrantData replaces the users and grant data served by this MySQL DB instance with the data which is present in the provided byte buffer, which is a persisted copy of a MySQLDb created with `Persist`. In contrast to LoadData, it *does* remove current data in the database.

This interface is appropriate for replication, when a replica needs to be brought up to date with a primary server.

This method does not support the legacy JSON serialization of users and grant data. In contrast to most methods which operate with persisted users and grants in *MySQLDb, this method _does_ restore persisted super users.

func (*MySQLDb) Persist 

func (db *MySQLDb) Persist(ctx *sql.Context, ed *Editor) error

Persist passes along all changes to the integrator.

This takes an Editor, instead of a Reader, since presumably we have just done a write. In any case, it's nice to not ACK a write until it is persisted, and the write lock which the Editor takes can help with not making these changes visible until it is persisted as well.

func (db *MySQLDb) Reader() *Reader

func (db *MySQLDb) SetPlugins(plugins map[string]PlaintextAuthPlugin)

func (*MySQLDb) UserActivePrivilegeSet 

func (db *MySQLDb) UserActivePrivilegeSet(ctx *sql.Context) PrivilegeSet

UserActivePrivilegeSet fetches the User, and returns their entire active privilege set. This takes into account the active roles, which are set in the context, therefore the user is also pulled from the context.

func (*MySQLDb) UserHasPrivileges 

func (db *MySQLDb) UserHasPrivileges(ctx *sql.Context, operations ...sql.PrivilegedOperation) bool

UserHasPrivileges fetches the User, and returns whether they have the desired privileges necessary to perform the privileged operation. This takes into account the active roles, which are set in the context, therefore the user is also pulled from the context.

func (*MySQLDb) ValidateHash 

func (db *MySQLDb) ValidateHash(salt []byte, user string, authResponse []byte, addr net.Addr) (mysql.Getter, error)

ValidateHash implements the interface mysql.AuthServer. This is called when the method used is "mysql_native_password".
