Sucrose 0.83.1 Release Notes

Announcement

This is our first Development Release in the 0.84 cycle. The code base has seen many refactoring efforts to improve the platform. To improve performance several heavy shell dependency have been dropped and the journal and the shell service has been merged into the shell. Furthermore the datastore has been rewritten, to simplify and improve maintainability. The API has been kept in place.

Sugar moved to use Gconf as a back end to store the profile. An ABI policy has been figured out and modules have been marked as STABLE / UNSTABLE / DEPRECATED.

Some enhancements have been made to the clipboard to provide visual consistency with the Sugar environment. And of course many many bugs have been fixed, which you can see in detail below.

Thanks

To everyone for bearing with us and keeping up the good work in this new release cycle!

Compatibility

When you upgrade a computer running an earlier version,

The old datastore will be updated to the new format.
Your old profile (in .sugar/default/config) will be imported into GConf

If you later downgrade from Sucrose 0.83.1 to an earlier version,

The datastore is incompatible
You will be prompted to enter all your profile settings like you are on first boot

Most of the activities in Sucrose 0.83.1 should be compatible with Sucrose 0.82 , the version shipped with OLPC Release 8.2.0. An exception is Browse, which depends on new versions of XULRunner and Hulahop. Read likewise may soon depend on a new version of Evince

sugar

Modularized the shell to have every major UI component like the frame the home view and the control panel reside in his own module and be self contained
Use gconf as a backend to store the profile.
Several heavy shell dependency have been dropped.
Merge of the journal and of the shell service into the shell
#5867 "Battery fully charged" shows up in error (battery is removed)
#8623 Jabber server description is ambiguous

Generate two themes based on SUGAR_SCALING
#8779 Merge sugar-artwork patches from debian package.
#8778 allow prelightning of buttons

sugar-base

Add dispatcher implementation from django
Mark modules as STABLE

sugar-datastore

The datastore has been rewritten, to simplify and improve maintainability. As a first step the API was not changed at all (other than removing removable devices support), so that the new implementation was swapped in without changes to activities and Sugar.
Drop for now the management of removable devices inside the DS. Removable devices support in Sugar should happen without intervention from the DS.
#8155 The datastore should hard link identical files, to handle repeated downloads of the same content without filling up NAND.
#4662 Support arbitrary metadata properties that activities wish to add
#6269 Degrade gracefully if a database gets corrupted- Basic functionality should only depend on the filesystem being available. Any other data structures (full text index) should be rebuildable from the filesystem.

sugar-presence-service

#7581 Don't ignore buddies without keys. This improve interoperability with non Sugar clients.
#7849 Display PS version in the log.
Use gconf to get Sugar profile settings.
#8444 Don't rely on the roster to check if a contact handle is channel specific or not - so PS will properly create Buddy objects discovered using Gadget. Furthermore, this workaround has the nice side effect to improve compatibility with bugged shared roster (as the one of ejabberd).
#5618 Discard invalid handles if InspectHandles failed.

etoys

This version copes with the datastore using byte arrays for strings, thus allowing to resume again
