<h1>KGS Protocol Description</h1> |
| 29 |
|
| 30 |
<p>This XML document describes the KGS protocol. It is also used |
| 31 |
to automatically generate the perl parser for all the messages and |
| 32 |
structures in the protocol. Adapting it to other languages should be |
| 33 |
almost trivial.</p> |
| 34 |
|
| 35 |
<p><b>Please note that wms has told me that he will change the |
| 36 |
protocol in response to my efforts. No problems with changing the |
| 37 |
protocol for good, but he does this just to make it more difficult |
| 38 |
to reverse-engineer it, since his changes are neither required, nor |
| 39 |
useful (they just make the protocol less robust, without adding added |
| 40 |
value). He doesn't even care that this locks out some users who cannot |
| 41 |
upgrade (cgoban2 isn't available for their platform anymore). It hurts |
| 42 |
to see such a waste of time and efforts that could have been used to |
| 43 |
fix bugs or improve the client...</b></p> |
| 44 |
|
| 45 |
<p>If you feel you need to update the visual appearance of this |
| 46 |
document, feel free to look <tt>doc/doc2html.xsl</tt> and improve |
| 47 |
it.</p> |

<h2>Structure and conventions of this document and the protocol</h2> |
| 56 |
|
| 57 |
<p>"ORIGIN: CLIENT" means messages send from the client to the server, |
| 58 |
while "ORIGIN: SERVER" means messages send by the server to the |
| 59 |
client.</p> |
| 60 |
|
| 61 |
<p>Everything on the wire is in little-endian format (what a shame).</p> |
| 62 |
|
| 63 |
<p>Primitive types are mostly integers (signed |
| 64 |
"<code>I</code><bits>", unsigned "<code>U</code><bits>"), |
| 65 |
ascii strings ("<code>username</code>"), or zero-terminated |
| 66 |
UCS2-Strings ("<code>STRING</code>"). Yes, I know java is supposed to |
| 67 |
do UTF-16, but no implementation seems to care...</p> |
| 68 |
|
| 69 |
<p>For the rest, go figure or bug me, <a href="mailto:pcg@goof.com">Marc Lehmann <pcg@goof.com></a></p> |
| 70 |
|
| 71 |
<h2>Stream and message structure.</h2> |
| 72 |
|
| 73 |
<p>After connecting to the server, a handshake byte is sent. It's |
| 74 |
the major version number of the protocol the client expects to |
| 75 |
receive. Version 3 and 4 are mostly the same, except that Version 4 |
| 76 |
clients expect server messages to be compressed, version 3 clients |
| 77 |
not.</p> |
| 78 |
|
| 79 |
<p>The server sends back his protocol number, which is always 3 in |
| 80 |
the current protocol. Most of the protocol variation is determined by |
| 81 |
the server using the client version that is used in the initial login |
| 82 |
message, not the initial handshake byte.</p> |
| 83 |
|
| 84 |
<p>After the initial handshake, the client sends uncompressed |
| 85 |
messages, while the server sends back a zlib-compressed |
| 86 |
stream (<a href="http://rfc1950.x42.com/">rfc1950</a> and <a |
| 87 |
href="http://rfc1950.x42.com/">rfc1951</a>).</p> |
| 88 |
|
| 89 |
<p>All messages have the same header:</p> |
| 90 |
|
| 91 |
<struct name="message_header"> |
| 92 |
<member name="_unknown" type="U16"/> |
| 93 |
<member name="length" type="U16"/> |
| 94 |
|
| 95 |
<p>The length is the length of the full message including the header.</p> |
| 96 |
|
| 97 |
<p>Beginning with version 2.5.x, a number is xored into the low |
| 98 |
byte of the length in <em>sent</em> packages only, as given by the |
| 99 |
following recurrence: <code>rand[0] = 0; rand[i+1] = msg[i].length |
| 100 |
+ (rand[i] * 0x04c2af9b + 0xfffffffb); xorbyte = rand >> |
| 101 |
24</code>, all in 32 bit unsigned iso-c arithmetic.</p> |
| 102 |
|
| 103 |
<member name="type" type="U16"/> |
| 104 |
<p>If the type is >= 0x4000 this is a message for a specific channel. The channel |
| 105 |
number is always the next U16.</p> |
| 106 |
|
| 107 |
<p>Beginning with version 2.5.x, a number is <em>added</em> on <em>received</em> |
| 108 |
messages only. The algorithm is as follows: |
| 109 |
|
| 110 |
<pre> |
| 111 |
msglen < 44: type = typefield |
| 112 |
msglen > 44: type = (typefield + rand[i]) % 0x10000 |
| 113 |
rand[0] = 0 |
| 114 |
rand[i+1] = username[type % length username] + rand[i] * (type - 0x6cdd) |
| 115 |
where username is the user name of the logged-in user. coooool. |
| 116 |
</pre> |
| 117 |
</p> |
| 118 |
|
| 119 |
</struct> |
| 120 |
|
| 121 |
<h2>Primitive types used in the protocol.</h2> |
| 122 |
|
| 123 |
<p>Apart from the basic types, I need to define some extra types to |
| 124 |
deal with fixed-point values (based on integer types) or fixed-length |
| 125 |
strings (either 7-bit-ascii or more limited (<code>A</code>), or UCS-2 |
| 126 |
based (<code>S</code>)).</p> |
| 127 |
|
| 128 |
<type name="username" type="A" length="10"/> |
| 129 |
|
| 130 |
<p>The basic user or login name, used throughout the protocol |
| 131 |
as a handle to the user.</p> |
| 132 |
|
| 133 |
<type name="roomname" type="S" length="25"/><!-- argh, how horribly broken --> |
| 134 |
|
| 135 |
<p>Many strings in the protocol are fixed-width for no good reason |
| 136 |
(maybe this is one reason for using compression in newer versions, as |
| 137 |
the packets itself are wasting lots of space.</p> |
| 138 |
|
| 139 |
<type name="realname" type="S" length="50"/> |
| 140 |
<type name="email" type="S" length="70"/> |
| 141 |
<type name="userinfo" type="S" length="1000"/> |
| 142 |
<type name="url" type="A" length="100"/> |
| 143 |
|
| 144 |
<p>Used in user_record.</p> |
| 145 |
|
| 146 |
<type name="locale" type="A" length="5"/> |
| 147 |
|
| 148 |
<p>A kind of locale specifier. It seems the general format seems to be |
| 149 |
lowercase language, underscore, uppercase location, e.g. en_US. More |
| 150 |
fancy specifications don't fit.</p> |
| 151 |
|
| 152 |
<type name="flag" type="U8" multiplier="1"/> |
| 153 |
|
| 154 |
<p>Just a simple boolean value. 0 means false, and 1 generally true, |
| 155 |
but I suggest ccepting != 0 as true.</p> |
| 156 |
|
| 157 |
<type name="komi16" type="I16" multiplier="2"/> |
| 158 |
<type name="komi32" type="I32" multiplier="2"/> |
| 159 |
<type name="komi324" type="I32" multiplier="4"/> |
| 160 |
|
| 161 |
<p>Komi values are multiplied by 2 to make them integer in the |
| 162 |
protocol. Well, *most* of the time at least...</p> |
| 163 |
|
| 164 |
<type name="result" type="I32" multiplier="2"/> |
| 165 |
|
| 166 |
<p>The game result is also multiplied by two to give it higher |
| 167 |
resolution. There are also special values for wins by time etc., either |
| 168 |
in result or in the score* types, or both :)</p> |
| 169 |
|
| 170 |
<type name="score16" type="I16" multiplier="4"/> |
| 171 |
<type name="score32" type="I32" multiplier="4"/> |
| 172 |
<type name="score1000" type="I32" multiplier="1000"/> |
| 173 |
|
| 174 |
<p>A score value (used for displaying the score at the end of a game) |
| 175 |
are multiplied by four for a change (the 0.25 resolution is not |
| 176 |
used). In game structures it is encoded by dividing by two, though, so |
| 177 |
watch out! And in some others, it's encoded by multiplying by 1000... |
| 178 |
yuck!</p> |
| 179 |
|
| 180 |
<type name="time" type="U32" multiplier="1000"/> |
| 181 |
|
| 182 |
<p>Time values are multiplied by 1000, giving them millisecond |
| 183 |
accuracy.</p> |
| 184 |
|
| 185 |
<type name="timestamp" type="U64" multiplier="1000"/> |
| 186 |
|
| 187 |
<p>64 bit timeval, milliseconds since posix epoch, e.g. <code>my |
| 188 |
($year, $month, $day) = (gmtime $date * 0.001)[5,4,3];</code></p> |
| 189 |
|
| 190 |
<type name="password" type="U64"/> |
| 191 |
|
| 192 |
<p>Password is a number calculated as follows (VERY insecure, basically |
| 193 |
plaintext!): <code>password = 0; for char in characters do password ← |
| 194 |
password * 1055 + ascii_code (char)</code></p> |
| 195 |

you should always send a text like "Jonathan's C client bersion 0.6" or somesuch, |
