<h1>KGS Protocol Description</h1> |
| 28 |
|
| 29 |
<p>This XML document describes the KGS protocol. It is also used |
| 30 |
to automatically generate the perl parser for all the messages and |
| 31 |
structures in the protocol. Adapting it to other languages should be |
| 32 |
trivial.</p> |
| 33 |
|
| 34 |
<p><b>Please note that the author of KGS has told me that he will |
| 35 |
change the protocol in response to my efforts. This does not |
| 36 |
necessarily mean that he will change the protocol just to make it |
| 37 |
difficult to reverse-engineer the protocol, but if this happens, |
| 38 |
I might not have the resources the track them, if they are too |
| 39 |
extensive. Anyway, he made it clear that no help whatsoever is to be |
| 40 |
expected.</b></p> |

<h2>Structure and conventions of this document and the protocol</h2> |
| 53 |
|
| 54 |
<p>"Send" means messages send from the client to the server, while |
| 55 |
"received" means messages send by the server to the client.</p> |
| 56 |
|
| 57 |
<p>Everything on the wire is in little-endian format (what a shame).</p> |
| 58 |
|
| 59 |
<p>Primitive types are mostly integers (signed |
| 60 |
"<code>I</code><bits>", unsigned "<code>U</code><bits>"), |
| 61 |
ascii strings ("<code>username</code>"), or zero-terminated |
| 62 |
UCS2-Strings ("<code>STRING</code>"). Yes, I know java is supposed to |
| 63 |
do UTF-16, but no implementation seems to care...</p> |
| 64 |
|
| 65 |
<p>For the rest, go figure or bug me, <a href="mailto:pcg@goof.com">Marc Lehmann <pcg@goof.com></a></p> |
| 66 |
|
| 67 |
<h2>Stream and message structure.</h2> |
| 68 |
|
| 69 |
<p>After connecting to the server, a handshake byte is sent. It's |
| 70 |
the major version number of the protocol the client expects to |
| 71 |
receive. Version 3 and 4 are mostly the same, except that Version 4 |
| 72 |
clients expect server messages to be compressed, version 3 clients |
| 73 |
not.</p> |
| 74 |
|
| 75 |
<p>The server sends back his protocol number, which is always 3 in |
| 76 |
the current protocol. Most of the protocol variation is determined by |
| 77 |
the server using the client version that is used in the initial login |
| 78 |
message, not the initial handshake byte.</p> |
| 79 |
|
| 80 |
<p>After the initial handshake, the client sends uncompressed |
| 81 |
messages, while the server sends back a zlib-compressed |
| 82 |
stream (<a href="http://rfc1950.x42.com/">rfc1950</a> and <a |
| 83 |
href="http://rfc1950.x42.com/">rfc1951</a>).</p> |
| 84 |
|
| 85 |
<p>All messages have the same header:</p> |
| 86 |
|
| 87 |
<struct name="message_header" send="yes" recv="yes"> |
| 88 |
<member name="_unknown" type="U16"/> |
| 89 |
<member name="length" type="U16"/> |
| 90 |
The length is the length of the full message including the header. |
| 91 |
<member name="type" type="U16"/> |
| 92 |
If the type is >= 0x4000 this is a message for a specific channel. The channel |
| 93 |
number is always the next U16. |
| 94 |
</struct> |
| 95 |
|
| 96 |
<h2>Primitive types used in the protocol.</h2> |
| 97 |
|
| 98 |
<p>Apart from the basic types, I need to define some extra types to |
| 99 |
deal with fixed-point values (based on integer types) or fixed-length |
| 100 |
strings (either 7-bit-ascii or more limited (<code>A</code>), or UCS-2 |
| 101 |
based (<code>S</code>)).</p> |
| 102 |
|
| 103 |
<type name="username" type="A" length="12"/> |
| 104 |
|
| 105 |
<p>The basic user or login name, used throughout the protocol |
| 106 |
as a handle to the user.</p> |
| 107 |
|
| 108 |
<type name="roomname" type="S" length="25"/><!-- argh, how horribly broken --> |
| 109 |
|
| 110 |
<p>Many strings in the protocol are fixed-width for no good reason |
| 111 |
(maybe this is one reason for using compression in enwer versions, as |
| 112 |
the packets itself are wasting lots of space.</p> |
| 113 |
|
| 114 |
<type name="realname" type="S" length="50"/> |
| 115 |
<type name="email" type="S" length="70"/> |
| 116 |
<type name="userinfo" type="S" length="1000"/> |
| 117 |
<type name="url" type="A" length="100"/> |
| 118 |
|
| 119 |
<p>Used in user_record.</p> |
| 120 |
|
| 121 |
<type name="locale" type="A" length="5"/> |
| 122 |
|
| 123 |
<p>A kind of locale specifier. It seems the general format seems to be |
| 124 |
lowercase language, underscore, uppercase location, e.g. en_US. More |
| 125 |
fancy specifications don't fit.</p> |
| 126 |
|
| 127 |
<type name="flag" type="U8" multiplier="1"/> |
| 128 |
|
| 129 |
<p>Just a simple boolean value. 0 means false, and 1 generally true, |
| 130 |
but I suggest ccepting != 0 as true.</p> |
| 131 |
|
| 132 |
<type name="komi16" type="I16" multiplier="2"/> |
| 133 |
<type name="komi32" type="I32" multiplier="2"/> |
| 134 |
|
| 135 |
<p>Komi values are multiplied by 2 to make them integer in the |
| 136 |
protocol.</p> |
| 137 |
|
| 138 |
<type name="result" type="I32" multiplier="2"/> |
| 139 |
|
| 140 |
<p>The game result is also multiplied by two to give it higher |
| 141 |
resolution. There are also special values for wins by time etc., either |
| 142 |
in result or in the score* types, or both :)</p> |
| 143 |
|
| 144 |
<type name="score16" type="I16" multiplier="4"/> |
| 145 |
<type name="score32" type="I32" multiplier="4"/> |
| 146 |
|
| 147 |
<p>A score value (used for displaying the score at the end of a game) |
| 148 |
are multiplied by four for a change (the 0.25 resolution is not |
| 149 |
used). In game structures it is encoded by dividing by two, though, so |
| 150 |
watch out!</p> |
| 151 |
|
| 152 |
<type name="time" type="U32" multiplier="1000"/> |
| 153 |
|
| 154 |
<p>Time values are multiplied by 1000, giving them millisecond |
| 155 |
accuracy.</p> |
| 156 |
|
| 157 |
<type name="timestamp" type="U64" multiplier="1000"/> |
| 158 |
|
| 159 |
<p>64 bit timeval, milliseconds since posix epoch, e.g. <code>my |
| 160 |
($year, $month, $day) = (gmtime $date * 0.001)[5,4,3];</code></p> |
| 161 |
|
| 162 |
<type name="password" type="U64"/> |
| 163 |
|
| 164 |
<p>Password is a number calculated as follows (VERY insecure, basically |
| 165 |
plaintext!): <code>password = 0; for char in characters do password ← |
| 166 |
password * 1055 + ascii_code (char)</code></p> |
| 167 |
|
| 168 |
<h2>Constants, enumeration and set types used in the protocol.</h2> |
| 169 |
|
| 170 |
<p>Baaah... not yet.</p> |
| 171 |
|
| 172 |
<h2>Structs used in send & receive messages</h2> |
| 173 |
|
| 174 |
<struct name="user" class="KGS::User"> |
| 175 |
|
| 176 |
Everywhere a user + flags is required, even used in some places |
| 177 |
where only a username is required. I see no general rule on when a |
| 178 |
complete user and when a partial user is required. |
| 179 |
|
| 180 |
<member name="name" type="username"/> |
| 181 |
<member name="flags" type="U32" default="1"/> |
| 182 |
</struct> |
| 183 |
|
| 184 |
<struct name="rules" class="KGS::Rules"> |
| 185 |
|
| 186 |
This structure is used for challanges as well as in the special |
| 187 |
TREE "subprotocol". It tightly encodes the game parameters. |
| 188 |
|
| 189 |
<member name="ruleset" type="U8"/> |
| 190 |
<member name="size" type="U8"/> |
| 191 |
<member name="handicap" type="U8"/> |
| 192 |
<member name="komi" type="komi16"/> |
| 193 |
<member name="timesys" type="U8"/> |
| 194 |
<member name="time" type="U32"/> |
| 195 |
<member name="interval" type="U32"/> |
| 196 |
byo-yomi time / canadian time |
| 197 |
<member name="count" type="U16"/> |
| 198 |
periods / moves |
| 199 |
</struct> |
| 200 |
|
| 201 |
<h2>Structs used in send messages</h2> |
| 202 |
|
| 203 |
<message type="0000" name="login" send="yes"> |
| 204 |
|
| 205 |
Send on the initial login. The password needs to be set when the |
| 206 |
guest flag is true. |
| 207 |
|
| 208 |
<member name="ver_major" type="U32" default="2"/> |
| 209 |
<member name="ver_minor" type="U32" default="4"/> |
| 210 |
<member name="ver_micro" type="U32" default="67"/> |
| 211 |
<member name="name" type="username"/> |
| 212 |
<member name="password" type="password" default="0"/> |
| 213 |
<member name="guest" type="flag" default="1"/> |
| 214 |
<member name="_unknown3" type="U16" default="0"/> |
| 215 |
<member name="locale" type="locale" default='"en_US"'/> |
| 216 |
<member name="clientver" type="DATA" default='"1.4.1_01:Swing app:Sun Microsystems Inc."'/> |
| 217 |
The "default" is the java vm version, not exactly he client version. However, |
| 218 |
you should always send a tetx like "Jonathan's C client bersion 0.6" or somesuch, |
| 219 |
so the server can, if necessary, block broken clients or client versions. |
| 220 |
</message> |
| 221 |
|
| 222 |
<message type="0007" name="req_userinfo" send="yes"> |

<message type="0007" name="req_userinfo" send="yes"> |
| 228 |

| 229 |
to "userinfo". |
| 230 |
<member name="setpass" type="flag"/> |
| 231 |
Should the password be updated? |
| 232 |
<member name="password" type="password" default="0"/> |
