1                   Virtual Moni Wiki HOWTO
2                                    Sung Kim (hunkim@cs.ucsc.edu)
3                                    12/26/2003 
4This is a quick and dirty patch to support virtual Moni wiki.
51. Motivation
6  We want to have a separated Wiki space for each project (virtual host) 
7  even though there are many projects in a box.
8  It is possible to have an http://wiki.kldp.org/<projectname> space for project, 
9  but still macros such as RecentChanges or TitleIndex shows all Wiki pages in the http://wiki.kldp.org/.
10  We want to see only changes in our wiki space. 
11  Why we care about other wiki pages created by other projects or hosts?
122. How it works
13   It is vary similar to the virtual host setting in Apache. 
14   Define a virtual host name with virtual part (*). 
15   And define wiki text directory name with virtual part (%0, %1, ... %n).
16   See more apache virtual host setting at http://httpd.apache.org/docs-2.0/mod/mod_vhost_alias.html
173. config.php
18  Those configuration are required to support virtual Wiki
19  - virtual_host: define virtual host name. You can put * for the virtual part
20    Ex: $virtual_host='wiki.*.kldp.org';
21  - virtual_sitename: define the virtual site name for the virtual host.
22    We can use %0, %2, ....
23    Ex: $virtual_sitename="MiniWIki for %1 project";
24  - virtual_text_dir: define text directory for virtual host wiki pages. 
25     %0, %1, ... will be replaced real host name.
26     Note that the host name starts %0.       
27    Ex: $virtual_text_dir=$data_dir.'/virtual_text/%1/';
28  - virtual_upload_dir: define upload directory for virtual host wiki pages. 
29     %0, %1, ... will be replaced real host name.
30     Note that the host name starts %0.       
31  - virtual_cache_dir: define cache directory for virtual host wiki pages. 
32     %0, %1, ... will be replaced real host name.
33     Note that the host name starts %0.       
34  - virtual_text_dir_auto_create: indicate weather create virtual text directory automatically.
35    Ex: $virtual_text_dir_auto_create=1;
36        $virtual_text_dir_auto_create=0;
37  - virtual_text_dir_auto_seed: indicate weather copy seed Wikipages automatically. 
38    It works only if virtual_text_dir_aito_create is set to 1.
39    Ex: $virtual_text_dir_auto_seed=1;
40        $virtual_text_dir_auto_seed=0;
41  - Virtual_text_dir_auto_create_ref: To avid creating unnecessarily virtual text directories
42    By typo, this option limits auto creation only from the defined http referrer. 
43    For example to create a virtual host text directory, the Wiki page must be connected from the http referrer page. 
44    Note that text directory creation is the only one time event.
45    After that, the virtual part doesn't check the http referrer.
46 
47    You can use wild card (*, ?) like file match. We use fnmatch to check the referrers.
48    If it is not defined and virtual_text_dir_auto_create is set, 
49    there is no limit to create virtual text directory.
50    Ex: $virtual_text_dir_auto_create_ref="*://kachi.org/projects/*"; 
51  For example with those setting, if a user connect to http://wiki.moni.kldp.org 
52  the virtual_text_dir would be "$data_dir/virtual_text/moni/", 
53  and sitename would be "MoniWiki for moni project". 
544. Directories and permission
55  The virtual_text directory should be created by user to use virtual Wiki 
56  unless virtual_text_dir_auto_create is set. 
57  
58  Note that you also need to create RCS directory in the virtual_text_dir to keep RCS files.
59  Otherwise you will see many *,v files in your wiki pages.  
60  
61  Make sure the httpd user can create files or directories in the virtual_text directory.
