[firebird-support] [FIREBIRD WIRE PROTOCOL] Documentation

[sdnetw...@gmail.com [firebird-support]]

Hi, 
 
i try to implement a driver and i play with the wire protocol but i need help ! 
 
i have found this doc : 
http://sourceforge.net/p/firebird/NETProvider/ci/3.1.1.0/tree/Documentation/FirebirdWireProtocol/
 
http://sourceforge.net/p/firebird/NETProvider/ci/3.1.1.0/tree/Documentation/FirebirdWireProtocol/
 => FirebirdWireProtocol.pdf 
 
For exemple the packet to send for a connect is : 
 
Int32 => Operation code (op_connect) 
Int32 => Operation code (op_attach) 
Int32 => Version (CONNECT_VERSION2) 
Int32 => Architecture type (Generic = 1) 
String => Database path 
Int32 => Protocol versions understood (1) 
Buffer => User identification 
Int32 => Protocol version (PROTOCOL_VERSION10) 
Int32 => Architecture type (Generic = 1) 
Int32 => Minimum type (2) 
Int32 => Maximum type (3) 
Int32 => Preference weight (2) 
 
the problem is that i don't find the doc that describe the buffer for user 
identification. 
 
i have take a look in the dotnet provider : and i found this : 
 
it is the code for the buffer 
 
user_id.WriteByte(1); => what is the 1 ? 
user_id.WriteByte((byte)user.Length); 
user_id.Write(user, 0, user.Length); 
// Host    name 
user_id.WriteByte(4); => what is the 4 ? 
user_id.WriteByte((byte)host.Length); 
user_id.Write(host, 0, host.Length); 
// Attach/create using this connection will use user verification 
user_id.WriteByte(6); => what is the 6 ? 
user_id.WriteByte(0); => what is the 0 ? 
 
more globally how i can found the description of this buffer ? and do you know 
a more detailed documentation about the wire protocol ? 
 
Thanks in advance.
