43  * Protocol commands between C-JDBC driver (client) and controller (server). All
44  * communications follow a classic RPC scheme: the driver sends a Command code,
45  * followed by argument(s) for some of the commands, and expects some answer(s),
46  * at the very least an error code or an exception. The server is event-driven;
47  * communications are inited by the client which is the one sending Protocol
48  * commands, so the verbs <cite>send</cite> and <cite>receive</cite> must be
49  * understood as from driver point of view. Almost all these commands are put on
50  * the wire by client class {@link org.objectweb.cjdbc.driver.Connection} and
51  * read (and answered) by class {@link
52  * org.objectweb.cjdbc.controller.virtualdatabase.VirtualDatabaseWorkerThread#run()}.
53  * The only exceptions are the following commands: <br>- ProtocolVersion<br>
54  * read only by {@link
55  * org.objectweb.cjdbc.controller.core.ControllerWorkerThread#run()}, which then
56  * constructs the connection and pass it to VirtualDatabaseWorkerThread for the
57  * rest of the execution of this command. <br>- Close<br>
58  * in addition to Connection, also sent by
59  * {@link org.objectweb.cjdbc.driver.ConnectionClosingThread#closeConnection(Connection)}
60  * <br>- Ping <br>
61  * sent on a dedicated connection only by {@link
62  * org.objectweb.cjdbc.driver.connectpolicy.ControllerPingThread#run()} and
63  * silently received only by (again) {@link
64  * org.objectweb.cjdbc.controller.core.ControllerWorkerThread#run()}
65  * <h2>Protocol Data Types</h2>
66  * <strong>optUTF</strong> is a custom type defined like this:
67  *
68  * <pre>
69  * (boolean false) | (boolean true; UTF somestring)
70  * </pre>
71  *
72  * <h3>Sent types</h3>
73  * <p>
74  * Several commands send a SQL query. All SQL queries sent on the wire use the
75  * same starting pattern, a <em>requestStub</em> defined below and in
76  * {@link org.objectweb.cjdbc.common.sql.AbstractRequest#AbstractRequest(CJDBCInputStream, int)}
77  * <br>
78  * <strong>requestStub</strong>
79  *
80  * <pre>
81  * UTF request : SQL query
82  * boolean EscapeProcessing
83  * UTF LINE_SEPARATOR
84  * Int timeout
85  * boolean autoCommit
86  * boolean isDriverProcessed
87  * </pre>
88  *
89  * <p>
90  * Queries that expect a result set (read commands mostly) send immediately
91  * after the requestStub a <em>subsetLengths</em> parameter, of type: <br>
92  * <strong>subsetLengths</strong>. See
93  * {@link org.objectweb.cjdbc.common.sql.AbstractRequest#receiveResultSetParams(CJDBCInputStream)}
94  *
95  * <pre>
96  * Int maxRows
97  * Int fetchSize
98  * </pre>
99  *
100  * <p>
101  * Depending on some configuration flag/state (shared by driver and controller),
102  * most query commands add an optional <em>skeleton</em> parameter of type
103  * optUTF.
104  * <h3>Received types</h3>
105  * <p>
106  * Several commands receive a ResultSet of type: <br>
107  * <strong>ResultSet</strong>
108  * {@link org.objectweb.cjdbc.driver.DriverResultSet#DriverResultSet(CJDBCInputStream)}
109  *
110  * <pre>
111  * {@link org.objectweb.cjdbc.driver.Field Field}[] fields
112  * {@link org.objectweb.cjdbc.driver.protocol.TypeTag}[] java column types
113  * ArrayList data
114  * optUTF hasMoreData: cursor name
115  * </pre> - <em>fields</em> is the description of the ResultSet columns. <br>-
116  * <em>data</em> is the actual data of the ResultSet. Each element of this
117  * list is an Object array holding one row of the ResultSet. The whole arraylist
118  * is serialized using standard Java serialization/readUnshared().
119  * <h3>Exceptions</h3>
120  * For almost every command sent, the driver checks if the reply is an exception
121  * serialized by the controller instead of the regular reply type. Most
122  * exceptions are put on the wire by
123  * {@link org.objectweb.cjdbc.controller.virtualdatabase.VirtualDatabaseWorkerThread#run()}
124  * TODO: finish the classification below. <br>
125  * Exception reply recognized by the driver in: <br>
126  * FetchNextResultSetRows, closeRemoteResultSet, RestoreConnectionState,
127  * setAutoCommit, getCatalog, getCatalogs, setCatalog,
128  * getControllerVersionNumber, DatabaseMetaDataGetTables,
129  * DatabaseMetaDataGetColumns, DatabaseMetaDataGetPrimaryKeys,
130  * DatabaseMetaDataGetProcedureColumns, DatabaseMetaDataGetTableTypes,
131  * DatabaseMetaDataGetTablePrivileges, DatabaseMetaDataGetSchemas,
132  * DatabaseMetaDataGetDatabaseProductName, DatabaseStaticMetadata <br>
133  * Exception reply ignored by the driver in: Close, Reset <br>
134  * Exceptions catched by instanceof(catch-all) default clause in: <br>
135  * setAutoCommit, <br>
136  * Commands not implemented at all by the driver: <br>
137  * GetVirtualDatabaseName, <br>
138  * TODO: <br>- exceptions and the server side (VirtualDatabaseWorkerThread)
139  * <br>- double-check arguments and replies <br>- better topic ordering
