18 | .SH NAME | |
19 | disorder_protocol \- DisOrder communication protocol | |
20 | .SH DESCRIPTION | |
21 | The DisOrder client and server communicate via the protocol described | |
22 | in this man page. | |
23 | .PP | |
b7de606b RK |
24 | The protocol is usually modified in each new version of the server. |
25 | .SH "MESSAGE STRUCTURE" | |
26 | A \fIline\fR is a sequence of printable Unicode characters encoded in UTF-8 and | |
27 | terminated by the octet 0x0A. | |
28 | Note that unlike some other protocols, a carriage return is not used as part of | |
29 | the end-of-line sequence. | |
30 | .PP | |
31 | A \fIcommand message\fR consists of a \fIcommand line\fR followed, in some cases, by a \fIbody\fR. | |
32 | Similarly a \fIresponse message\fR consists of a \fIresponse line\fR followed | |
33 | sometimes by a \fIbody\fR. | |
460b9539 | 34 | .PP |
b7de606b RK |
35 | A \fIbody\fR consists of a sequence of dot-stuffed lines followed by a line |
36 | containing a single full stop character. | |
37 | Dot-stuffing means that any line in the body starting with a full stop have | |
38 | another full stop inserted at the start prior to transmission, and removed | |
39 | again after reception. | |
460b9539 | 40 | .PP |
b7de606b RK |
41 | Whether a command message includes a body depends on the specific command being |
42 | sent; see below for details. | |
43 | This is also true of reply messages, although it is guaranteed that if the is a | |
44 | response body then the reply status code (see below) will end with the digit 3. | |
460b9539 | 45 | .PP |
b7de606b RK |
46 | Command lines, and some response lines, are split into \fIfields\fR. |
47 | Fields are separated by one or more spaces and may be \fIunquoted\fR or | |
48 | \fIquoted\fR. | |
fc80bbcd | 49 | .PP |
b7de606b RK |
50 | An \fIunquoted field\fR can contain any (non-control) characters except for a |
51 | space, quotation mark or apostrophe. | |
52 | They are always at least one character long. | |
53 | .PP | |
54 | A \fIquoted field\fR begins with a quotation mark or apostrophe and is | |
55 | terminated by the same character. | |
56 | Any occurrence of the backslash or the surrounding quotation mark must be | |
57 | escaped. | |
58 | The full set of escapes permitted is: | |
59 | .TP | |
60 | .B \e\e | |
61 | Backslash | |
62 | .TP | |
63 | .B \e" | |
64 | Quotation mark | |
65 | .\" " | |
66 | .TP | |
67 | .B \e\(aq | |

460b9539 | 73 | .SH COMMANDS |
b7de606b | 74 | Commands always have a command name as the first field of the line. |
460b9539 | 75 | .PP |
76 | All commands require the connection to have been already authenticated unless | |
c0c23a60 | 77 | stated otherwise. |

877 | Filenames are in UTF-8 even if the collection they come from uses some other |
878 | encoding - if you want to access the real file (in such cases as the filenames | |
879 | actually correspond to a real file) you'll have to convert to whatever the | |
880 | right encoding is. | |
