Member Function Documentation

bool drizzle_plugin::ClientMySQLProtocol::authenticate ( void ) [virtual]

Perform handshake and authorize client if needed.

Implements drizzled::plugin::Client.

Definition at line 169 of file mysql_protocol.cc.

References sendError(), and sendOK().

void drizzle_plugin::ClientMySQLProtocol::close ( void ) [virtual]

Close the client object.

Implements drizzled::plugin::Client.

Definition at line 152 of file mysql_protocol.cc.

bool drizzle_plugin::ClientMySQLProtocol::flush ( void ) [virtual]

Flush all data that has been buffered with store() methods.

Return values:

Boolean indicating success or failure.

Implements drizzled::plugin::Client.

Definition at line 142 of file mysql_protocol.cc.

Referenced by sendFields().

int drizzle_plugin::ClientMySQLProtocol::getFileDescriptor ( void ) [virtual]

Get file descriptor associated with client object.

Return values:

File	descriptor that is attached, -1 if none.

Implements drizzled::plugin::Client.

Definition at line 122 of file mysql_protocol.cc.

virtual Session* drizzled::plugin::Client::getSession ( void ) [inline, virtual, inherited]

Get attached session from the client object.

Return values:

Session object that is attached, NULL if none.

Definition at line 57 of file client.h.

bool drizzle_plugin::ClientMySQLProtocol::isConnected ( ) [virtual]

Check to see if the client is currently connected.

Return values:

Boolean value representing connected state.

Implements drizzled::plugin::Client.

Definition at line 127 of file mysql_protocol.cc.

bool drizzle_plugin::ClientMySQLProtocol::isReading ( void ) [virtual]

Check to see if the client is actively reading.

Return values:

Boolean value representing reading state.

Implements drizzled::plugin::Client.

Definition at line 132 of file mysql_protocol.cc.

bool drizzle_plugin::ClientMySQLProtocol::isWriting ( void ) [virtual]

Check to see if the client is actively writing.

Return values:

Boolean value representing writing state.

Implements drizzled::plugin::Client.

Definition at line 137 of file mysql_protocol.cc.

bool drizzle_plugin::ClientMySQLProtocol::readCommand	(	char **	packet,
		uint32_t *	packet_length
	)		`[virtual]`

Read command from client.

Implements drizzled::plugin::Client.

Definition at line 215 of file mysql_protocol.cc.

References drizzled::Diagnostics_area::DA_ERROR, sendError(), sendOK(), and drizzled::Session::variables.

void drizzle_plugin::ClientMySQLProtocol::sendEOF ( void ) [virtual]

Send eof (= end of result set) to the client.

The eof packet has the following structure:

254 (DRIZZLE_PROTOCOL_NO_MORE_DATA) : Marker (1 byte)
warning_count : Stored in 2 bytes; New in 4.1 client
status_flag : Stored in 2 bytes; For flags like SERVER_MORE_RESULTS_EXISTS.

Note that the warning count will not be sent if 'no_flush' is set as we don't want to report the warning count until all data is sent to the client.

Implements drizzled::plugin::Client.

Definition at line 400 of file mysql_protocol.cc.

References drizzled::Diagnostics_area::can_overwrite_status, and writeEOFPacket().

void drizzle_plugin::ClientMySQLProtocol::sendError	(	const drizzled::error_t	sql_errno,
		const char *	err
	)		`[virtual]`

Send a error string to client.

For SIGNAL/RESIGNAL and GET DIAGNOSTICS functionality it's critical that every error that can be intercepted is issued in one place only, my_message_sql.

Implements drizzled::plugin::Client.

Definition at line 415 of file mysql_protocol.cc.

References drizzled::Diagnostics_area::can_overwrite_status.

Referenced by authenticate(), and readCommand().

bool drizzle_plugin::ClientMySQLProtocol::sendFields ( drizzled::List< drizzled::Item > * list ) [virtual]

Send name and type of result to client.

Sum fields has table name empty and field_name.

Parameters:

Session Thread data object

list List of items to send to client

flag

Bit mask with the following functions:

1 send number of rows
2 send default values
4 don't write eof packet

Return values:

0	ok
1	Error (Note that in this case the error is not sent to the client)

Implements drizzled::plugin::Client.

Definition at line 487 of file mysql_protocol.cc.

References flush(), and writeEOFPacket().

void drizzle_plugin::ClientMySQLProtocol::sendOK ( void ) [virtual]

Return ok to the client.

The ok packet has the following structure:

0 : Marker (1 byte)
affected_rows : Stored in 1-9 bytes
id : Stored in 1-9 bytes
server_status : Copy of session->server_status; Can be used by client to check if we are inside an transaction. New in 4.0 client
warning_count : Stored in 2 bytes; New in 4.1 client
message : Stored as packed length (1-9 bytes) + message. Is not stored if no message.

Parameters:

session	Thread handler
affected_rows	Number of rows changed by statement
id	Auto_increment id for first row (if used)
message	Message to send to the client (Used by mysql_status)

Implements drizzled::plugin::Client.

Definition at line 333 of file mysql_protocol.cc.

virtual void drizzled::plugin::Client::setSession ( Session * session_arg ) [inline, virtual, inherited]

Attach session to the client object.

Parameters:

[in] session_arg Session object to attach, or NULL to clear.
