   1 Deprecating GConf
   2 =================
   3
   4  Gnome is deprecating GConf in favour of GSettings. This is the short story.
   5  We so have to migrate several pool of datas.
   6
   7  Starting with 3.1.0, Nautilus-Actions is provided with the needed migration
   8  tools, whether the migration may occur automatically (for users items and
   9  preferences), or the system admin must run a script (for mandatory items).
  10
  11  Note that this does not break backward compatibility. The 3.1.x serie of
  12  Nautilus-Actions may still be run on a "old" platform. The oldest supported
  13  as of January 2011 is Ubuntu 8 LTS.
  14
  15  1. Items, menus and actions, stored in GConf backend
  16  ----------------------------------------------------
  17  Historically, actions, then menus, were stored in GConf. These are user items.
  18
  19  A system admin was free to define mandatory menus and actions, and to store
  20  them in the Mandatory pool of GConf. Such defined items are so available to
  21  all users, though as read-only items.
  22
  23    1a. Migrating user items
  24    ------------------------
  25    The good news is:
  26    user items are automatically migrated from GConf to .desktop files.
  27
  28    The migration happens when the user runs the Nautilus-Actions Configuration
  29    Tool user interface, or when the Nautilus-Actions menu plugin is loaded
  30    by the Nautilus file-manager, or when the user runs one of the command-line
  31    tools nautilus-actions-new or nautilus-actions-run.
  32
  33    The nautilus-actions-print command-line tool, along with na-delete-xmltree,
  34    and na-print-schemas installed in PKGLIBEXECDIR, have no effect on the
  35    migration process.
  36
  37    The new .desktop files are stored in HOME/.local/file-manager/actions.
  38
  39    When the migration of its items has occurred, the GConf I/O Provider is
  40    disabled, both for reading and writing.
  41
  42    1b. Migrating mandatory items
  43    -----------------------------
  44    The bad news is:
  45    the system admin has to manually run PKGLIBEXECDIR/na-gconf2key.sh script
  46    as root in order to migrate existing mandatory items to .desktop files.
  47
  48    The new .desktop files default to be stored in /usr/share/file-manager/actions.
  49
  50    It is enough to run this script once, e.g. when installing for the first time
  51    a recent enough version (>= 3.1.0) of Nautilus-Actions.
  52
  53    Command-line example:
  54    # /usr/libexec/nautilus-actions/na-gconf2key.sh -delete -nodummy
  55
  56  2. User preferences stored in GConf
  57  -----------------------------------
  58  Mandatory and user preferences follow the same migration rules that items:
  59
  60  - user preferences are automatically migrated,
  61  - mandatory preferences have to be manually migrated by the system admin.
  62
  63  Preferences are renamed and reorganized:

 124  3. Sysadmin reserved mandatory keys
 125  -----------------------------------
 126  These were
 127    /apps/nautilus-actions/mandatory/
 128      all/locked
 129      na-desktop/locked
 130      na-gconf/locked
 131
 132  These keys are just ignored if they are not in the mandatory GConf pool, i.e.
 133  if they happens to be eventually editable by the user.
 134
 135  If these keys are actually in the system mandatory GConf pool, they are renamed
 136  in the following way:
 137
 138  GConf                                      Group      Key
