Examples with SocketConnection com.mysql.cj.protocol.SocketConnection used on opensource projects

Example 1 with SocketConnection

use of com.mysql.cj.protocol.SocketConnection in project aws-mysql-jdbc by awslabs.

the class SimplePacketReaderTest method basicHeaderRead.

// the basic operation: make sure header bytes are interpreted properly
@Test
public void basicHeaderRead() throws IOException {
    RuntimeProperty<Integer> maxAllowedPacket = new JdbcPropertySetImpl().getProperty(PropertyKey.maxAllowedPacket);
    maxAllowedPacket.setValue(100000);
    // mix up the bits so we know they're interpreted correctly
    SocketConnection connection = new FixedBufferSocketConnection(new byte[] { 3, 2, 1, 42 });
    MessageReader<NativePacketHeader, NativePacketPayload> reader = new SimplePacketReader(connection, maxAllowedPacket);
    assertEquals(-1, reader.getMessageSequence());
    NativePacketHeader hdr = reader.readHeader();
    assertEquals(65536 + 512 + 3, hdr.getMessageSize());
    assertEquals(42, hdr.getMessageSequence());
    assertEquals(42, reader.getMessageSequence());
    reader.resetMessageSequence();
    assertEquals(0, reader.getMessageSequence());
}

Example 2 with SocketConnection

use of com.mysql.cj.protocol.SocketConnection in project aws-mysql-jdbc by awslabs.

the class SimplePacketReaderTest method readBasicPayload.

// trivial payload test
@Test
public void readBasicPayload() throws IOException {
    RuntimeProperty<Integer> maxAllowedPacket = new JdbcPropertySetImpl().getProperty(PropertyKey.maxAllowedPacket);
    SocketConnection connection = new FixedBufferSocketConnection(new byte[] { 3, 2, 1, 6, 5, 4 });
    MessageReader<NativePacketHeader, NativePacketPayload> reader = new SimplePacketReader(connection, maxAllowedPacket);
    NativePacketPayload b = reader.readMessage(Optional.empty(), new NativePacketHeader(new byte[] { 3, 0, 0, 0 }));
    assertEquals(3, b.getByteBuffer()[0]);
    assertEquals(2, b.getByteBuffer()[1]);
    assertEquals(1, b.getByteBuffer()[2]);
    // make sure the first only consumed the requested 3 bytes
    b = reader.readMessage(Optional.empty(), new NativePacketHeader(new byte[] { 3, 0, 0, 0 }));
    assertEquals(6, b.getByteBuffer()[0]);
    assertEquals(5, b.getByteBuffer()[1]);
    assertEquals(4, b.getByteBuffer()[2]);
}

Example 3 with SocketConnection

use of com.mysql.cj.protocol.SocketConnection in project aws-mysql-jdbc by awslabs.

the class NativeSession method connect.

public void connect(HostInfo hi, String user, String password, String database, int loginTimeout, TransactionEventHandler transactionManager) throws IOException {
    this.hostInfo = hi;
    // reset max-rows to default value
    this.setSessionMaxRows(-1);
    // TODO do we need different types of physical connections?
    SocketConnection socketConnection = new NativeSocketConnection();
    socketConnection.connect(this.hostInfo.getHost(), this.hostInfo.getPort(), this.propertySet, getExceptionInterceptor(), this.log, loginTimeout);
    // physical connection is responsible *only* for I/O streams
    if (this.protocol == null) {
        this.protocol = NativeProtocol.getInstance(this, socketConnection, this.propertySet, this.log, transactionManager);
    } else {
        this.protocol.init(this, socketConnection, this.propertySet, transactionManager);
    }
    // use protocol to create a -> session
    // protocol is responsible for building a session and authenticating (using AuthenticationProvider) internally
    this.protocol.connect(user, password, database);
    this.isClosed = false;
    this.commandBuilder = new NativeMessageBuilder(this.getServerSession().supportsQueryAttributes());
