Functions

func NewListener

func NewListener(listenerCfg mysql.ListenerConfig) (server.ProtocolListener, error)

NewListener creates a new Listener.

func NewListenerWithOpts

func NewListenerWithOpts(listenerCfg mysql.ListenerConfig, opts ...ListenerOpt) (server.ProtocolListener, error)

func RunInMemory

func RunInMemory(cfg *servercfg.DoltgresConfig) (*svcs.Controller, error)

RunInMemory starts the server based on the given args, while also using RAM as the backing store. The returned WaitGroup may be used to wait for the server to close.

func RunOnDisk

func RunOnDisk(ctx context.Context, cfg *servercfg.DoltgresConfig, dEnv *env.DoltEnv) (*svcs.Controller, error)

RunOnDisk starts the server based on the given args, while also using the local disk as the backing store. The returned WaitGroup may be used to wait for the server to close.

Types

type ConnectionHandler

type ConnectionHandler struct {
	// contains filtered or unexported fields
}

ConnectionHandler is responsible for the entire lifecycle of a user connection: receiving messages they send, executing queries, sending the correct messages in return, and terminating the connection when appropriate.

func NewConnectionHandler

func NewConnectionHandler(conn net.Conn, handler mysql.Handler) *ConnectionHandler

NewConnectionHandler returns a new ConnectionHandler for the connection provided

func (*ConnectionHandler) Conn

func (h *ConnectionHandler) Conn() net.Conn

Conn returns the underlying net.Conn for this connection.

func (*ConnectionHandler) HandleConnection

func (h *ConnectionHandler) HandleConnection()

HandleConnection handles a connection's session, reading messages, executing queries, and sending responses. Expected to run in a goroutine per connection.

type ConvertedQuery

type ConvertedQuery struct {
	String       string
	AST          vitess.Statement
	StatementTag string
}

ConvertedQuery represents a query that has been converted from the Postgres representation to the Vitess representation. String may contain the string version of the converted query. AST will contain the tree version of the converted query, and is the recommended form to use. If AST is nil, then use the String version, otherwise always prefer to AST.

type Listener

type Listener struct {
	// contains filtered or unexported fields
}

Listener listens for connections to process PostgreSQL requests into Dolt requests.

func (*Listener) Accept

func (l *Listener) Accept()

Accept handles incoming connections.

func (*Listener) Addr

func (l *Listener) Addr() net.Addr

Addr returns the address that the listener is listening on.

func (*Listener) Close

func (l *Listener) Close()

Close stops the handling of incoming connections.

type ListenerOpt

type ListenerOpt func(*Listener)

func WithCertificate

func WithCertificate(cert tls.Certificate) ListenerOpt

type PortalData

type PortalData struct {
	Query        ConvertedQuery
	IsEmptyQuery bool
	Fields       []*querypb.Field
	BoundPlan    sql.Node
}

type PreparedStatementData

type PreparedStatementData struct {
	Query        ConvertedQuery
	ReturnFields []*querypb.Field
	BindVarTypes []int32
}
