 ChangeLog
 =========
 
+2006/09/19
+5406: Main multiuser patch, see docs/multiuser.txt for details
+      thx to jave, pango, zet and many other people who have helped
+      to make this work possible
+- this patch is experimental, if it breaks, you can keep the pieces;-)
+- multigroup_usercommit.patch and multigroup_su.patch are not included
+- this patch is still not finished, the To-Do list in docs/multiuser.txt
+  is still long, also GUI protocol updates have to be implemented.
+  To manage users, groups and files, its best to use the HTML interface,
+  multiuser commands can also be used in Telnet interface.
+-------------------------------------------------------------------------------
 2006/09/17 version 2.8.1 = tag release-2-8-1
 5401: Fix question whether to compile Ocaml with some bash versions (pango)
 5400: Allow use of Ocaml 3.09.3, keep 3.09.2 as default

+Description of multiuser patch
+==============================
+This file provides some HowTos and internals about the new multiuser
+functionality of MLDonkey. The goal is to provide a p2p-service to be used
+by more than user and where each user has its own environment in provided
+by the daemon.
+
+Some basics and definitions
+===========================
+User "admin" and all users belonging to a group where group_admin = true can
+see all files in any case and can use all functions of MLDonkey.
+
+file_owner in this text means one user which owns a downloading file,
+file_group means one group the file belongs to, file_owner must be a member of
+this group, both values are saved in files.ini.
+
+New options (displayed options are default values)
+==================================================
+users.ini
+---------
+- users is kept unchanged for compatibility
+- users2 is extended with these settings:
+
+     user_groups = []
+A list of groups the user belongs to, this user can view all files
+which belong to one of the groups
+
+The default group of the user, the user must also be a member of this
+group. File_group of new downloads started by the user are automatically
+assigned to this value. This value can be None, this means the file is
+only visible to the file_owner (and admins, of course).
+     user_default_group = mldonkey
+
+E-mail address to sent commit notifications to. Globals option "mail"
+can still be used for admins, if both addresses match only one mail is sent.
+     user_mail = ""
+
+Not implemented yet, planned feature is to have user specific directories
+below global incoming directories.
+     user_commit_dir = ""
+
+Like global option max_concurrent_downloads this implements a user-specific
+limit of the maximum number of concurrent files a user can download. Other
+downloads are queued, this is done by round-robin. If the sum of
+user_max_concurrent_downloads from all users is bigger than
+max_concurrent_downloads less downloads than user_max_concurrent_downloads
+are in downloading state. 0 means no user-specific limit.
+Users can change file priorities the control which files are not queued.
+     user_max_concurrent_downloads = 0
+
+- groups, new option
+At least one group named "mldonkey" with group_admin = true must exist
+
+This option is not implemented yet
+     group_mail = ""
+
+Option to control if the group has admin rights. All users belonging to such a
+group have the same rights as user "admin".
+     group_admin = true
+
+
+files.ini
+---------
+- each file has two new options in files.ini
+file_owner: the incoming directory of the owner is used for commit,
+            if the user does not exist "admin" is used
+file_group: default value for a new download is user_default_group 
+            if file_owner is not member of file_group or the group does not
+            exist, the value user_default_group is used
+
+
+Commands to control multiuser features/data
+===========================================
+chgrp <group> "<num>"
+change group of download <num> to <group>, group = none for private file
+
+chown <user> "<num>"
+change owner of download <num> to <user>
+
+groupadd <group> <admin: true | false> [<mail>]
+add new mldonkey group
+
+passwd <passwd>
+change own password
+
+useradd <user> <passwd>
+add new mldonkey user/change user password
+
+usercommit <user> <dir>
+change user specific commit directory
+
+userdel <user>
+remove a mldonkey user
+
+userdls <user> <num>
+change number of allowed concurrent downloads
+
+usermail <user> <mail>
+change user mail address
+
+users
+use this command in HTML interface for a small GUI to control users
+
+whoami
+print logged-in user name
+
+
+Updating from a non-multiuser MLDonkey
+======================================
+When updating all files have file_owner "admin" and file_group "mldonkey".
+All existing users have
+user_default_group = "mldonkey" and user_groups = ["mldonkey"].
+This means all users can use all features of MLDonkey and see all files
+in use by MLDonkey core.
+
+To hide user downloads from each other create a new group with
+group_admin = false and assign all users to this group and remove them
+from all admin groups
+
+
+Additional features
+===================
+- file_completed_cmd has new environment variables $FILE_OWNER and $FILE_GROUP
+- remove option enable_user_config, replaced by membership of admin groups
+
+To-Do
+======
+- check on start-up of group "mldonkey" exists and if it has admin rights
+- implement groupdel + prevent deletion if group is in use
+- prevent groupdel if group is file_group of current downloads
+- prevent groupdel if group has members
+- implement user_commit_dir (work is done in multigroup_usercommit.patch)
+  Besides supporting the option user_commit_dir the mechanism to choose
+  incoming directory is changed.
+  Incoming directories are saved in a list of directories in option
+  shared_directories. They have a special sharing_strategy named 
+  incoming_directories (for BT multifile downloads only) or incoming_files.
+  Current implementation uses the first directory with this stratagy found in
+  the list.
+  The new implementation (already done) iters the list of marked incoming
+  directories until one is found with enough free space. If no usable directory
+  is found, the file will stay in the list of files to be committed.
+- implement group_mail
