Community SSU

What is it?
Seamless Software Update (SSU), is the term Nokia formerly used for over-the-air updates of Maemo (generally marketed as Maemo Update as of Maemo 5).

The Community Seamless Software Update (CSSU) is being developed by the Maemo community as a continuation of, and expansion on, Nokia's update support. It aims to deliver fixes which would be difficult to deliver through Extras (like core Maemo packages). It won't, however, bundle software which can be installed through the Extras repositories.

There are two such efforts for the Maemo platform. This page describes the one for Fremantle (Maemo 5, as used in the Nokia N900). The Diablo Community Project is doing the same for Diablo (Maemo 4.1, as used in the Nokia N800, N810 and N810 WiMAX Edition).

Who is it for?
Since the release of the stable branch cssu is meant to be for all N900 users/owners. Power-users, developers, Nokia/Maemo/MeeGo engineers, testers, documentation writers and those willing to risk a re-flash in order to help can still install the testing version and stay as bleeding edge as possible

Installation
"Newbie" Video Tutorial: http://www.youtube.com/watch?v=uMHxo1ALXNE

0. Install backupmenu. Do a full backup of your system. Get your battery charged up to state "green" - not mandatory but all highly recommended, as usual. Plug in wallcharger. Get softdrink of your choice :-)
 * 1) Upgrade to at least PR1.3, Nokia's last official major Maemo 5 update. PR1.3.1 is fine as well. If you're unsure if you have, Settings > About product should show Version beginning with 20.2010.36(PR1.3) or 21.2011.38(PR1.3.1). Make sure you have no too weird catalog settings in Application manager, esp it's recommended you never disable the core Nokia SSU repositories.
 * 2) In case you have modified hildon-desktop installed remove it before taking further steps, all your settings will work since cssu does include all m-h-d changes.
 * 3) Think a minute if you want to be a tester supporting CSSU bleeding edge, or you rather need a rock solid CSSU, then click on the according Install stable or testing button above.
 * 4) Hildon Application Manager (HAM) will launch and begin processing (be patient). There are a series of installations for which it will prompt you with messages and warnings. Click "Accept" and "Done" for each to install.
 * 5) Once this is completed, close HAM and go into the applications menu. Tap the Community SSU icon. This will run through a series of scripts to ensure the community repository are set up.
 * 6) HAM will re-open and present a system upgrade called Maemo 5 Community SSU. Once installed, your device will reboot.
 * 7) If you installed the stable version and have edited your transistions.ini before installing, then you'll find your old ini in /usr/share/hildon-desktop/transistions.ini.precssu. You can either just copy it over the new one and miss out on the new features, or incorporate your changes.

Features
You find there how to use new features such as Thomas Perl's hildon-desktop improvements and the status of applications in Portrait Mode with.

Changelog
lists all changes from stock PR1.3 to CSSU and between various CSSU releases.

Contributing
Can you write documentation? If so, it'd be great to flesh out the wiki page with installation instructions (to make it easy for users to install without worrying about missing a step or getting it wrong); explain more about the SSU and generally spruce up the wiki page and maintain things like the changelogs etc.

Were you involved in developing Maemo? If so, with Nokia now looking to Harmattan and MeeGo, we'd love to see your itches addressed in the Community SSU (CSSU). Have you always wanted to implement something in hildon-desktop, but Management stood in your way? We'd love to have it!

Have you written a patch for Maemo? Raise a bug and let's get it in the CSSU.

Are you a developer? There are numerous patches floating around for hildon-desktop; but they can't be included in the CSSU until they are configurable (via gconf) and default to off.

Want to test? Not only testing this release, but writing test scripts so that each release of the CSSU can get sanity checked before unleashing it into a "stable" repo for end-users. How do we do it? What should be tested? How is it organised?

Want to organise? There's still lots of process left to organise; hopefully there'll be bugs and features to triage and manage in bugs.maemo.org as well as communication of the testing, releases and end-user readiness of the CSSU.

Have great ideas? If you have suggestions that you think could be picked up by the CSSU developers, please add them here: CSSU Requests. However see the notice above about CSSU not going to include anything that better gets implemented as a normal app. Nonetheless CSSU actually will host apps that are specific to CSSU core system, the orientation-lock applet being first of a possibly ever increasing number.

QA and bugs
Quality is of paramount importance to the Community SSU. There are, therefore, two repositories: testing and stable. Changes are carefully tested, with an extensive set of tests, before things are made "stable".

If you have found a bug, in either the testing or stable releases, please raise a bug. Getting involved through testing, bug triaging and running of the tests is a good way to get involved; as, of course, is writing documentation!

Development
The Community SSU is developed and managed through Gitorious. Bugs are tracked in Bugzilla. Collaboration largely happens on IRC. Getting involved through development, bug triaging and managing developers is a good way to get involved.
