Maemo 5 Extras reaches 3.5M downloads

The maemo.org Extras repository for community contributed software has reached 3.5 million downloads for Maemo 5. Software is offered through maemo.org free of charge and the repository is open to all developers. maemo.org Downloads is the web interface to the software available through maemo.org Extras.

We see the number of downloads grow every day. This makes the maemo.org Extras repository a great place for developers to get their software in the hands of end users. If you are interested in publishing your software through maemo.org, please visit the wiki.

We introduced improved download statics to show developers exactly how many downloads they received. The FM Radio Player application has received over 138000 downloads. FM Radio stats below:

The Extras repository has only been enabled on N900 devices by default in a recent software update. Before this update users needed to manually activate the repository in their Application Manager's catalog list. Also keep in mind that the Application Manager is not very easy to find, because of it being put in the 'More' menu.

Overall I think the number is quite impressive as these devices aren't available for a long time and a lot of people had problems even finding a device in their country.

Backwards compatibility broken PR1.1 SDK

I've been discussing this issue with some people before as hypothetical case, but now it seems that we run into it: Compiling and application against the PR1.1 SDK creates packages which can not be installed on earlier firmware releases.

In this case we have have a libosso version which is higher than the one in previous releases. As this dependency gets automatically added when compiling in the PR1.1 SDK this poses a problem.

The autobuilder uses the repository.maemo.org repository, so it automatically uses newer packages when they are available.

For Extras this means that install of an application which is compiled against the new SDK fails without any description we can expect an end-user to understand. This is something which should be prevented.

How can we work around this problem:

1: Only compile against the original SDK.

This prevents new features from ever be available to developers, but should work until there is real API/ABI breakage in a new firmware.

2: Use version specific repositories

This needs Application Manager support as we need to fetch from a separate repository every time. Also requires us to build against every sdk version known to man.

3: Depend on >= mp-fremantle-generic-pr | maemo-version

We would need a hack in the autobuilder to add depends to pr and maemo version. This way a user needs to upgrade to at least the required firmware image. I think this will make it easier for an end-user to understand what is happening.

We could, with help of the AM team, even detect in the AM that a firmware upgrade is required and give a the end user a nice warning/description.

Currently the AM doesn't have any means to detect which firmware version a package requires. Option 3 solve that issue at the same time.

If you have an alternative solution on how to go about fixing this
issue, then please let me know.

Maemo 5 Downloads now available

For Maemo 5 applications which managed to reach the Extras repository through the community QA testing queue, maemo.org Downloads now has a home.

The Download catalog automatically imports all information for applications in Fremantle Extras. The only thing you need to add is a nice screenshot. (Or more if you want.)

There are quite some applications in the QA testing queue which are almost ready for promotion to Extras. We should see more entries after the Summit.

If you are coming to the Maemo Summit in Amsterdam, see you there!

New features autobuilder and Extras Assistant

Rejecting packages when the same version is uploaded for the second time.

The autobuilder has been modified to reject a package when the same version is already available in the extras-devel repository. This change will force developers to increase their package version number after each successful upload and build. In the past we've had problems in the repository where a package was uploaded twice and caused 'Size Mismatch' errors.

Package signing no longer required.

The autobuilder and Extras Assistant no longer require packages to be GPG signed. It seemed to cause a lot of grief for developers without any real benefits. This change is targetted to making uploading packages easier. Every uploader has to be authenticated to upload a package, so we can already trace back the uploader. The autobuilder signs packages which are moved into the repository.

Upload to multiple repositories at the same time.

You can now use the Extras Assistant to upload a source package to chinook and diablo at the same time. No need to do two separate uploads anymore. This feature has been requested for quite some time, let's hope it helps.

Reducing number of external repositories #1

In my talk at the Maemo summit 2008, I talked about starting an effort to reduce the number of external repositories. Talking about this helps, but actively contacting developers and repository owners helps even more. This week I started by creating a list of all repositories we need to target. When this was done, I started to contact a lot of developers to convince them to move their packages into Extras and then close their repository.

A funny thing to mention is: Nobody had any objections to this.

Most responses were apologies for not doing it sooner. When I started this, I expected to have some resistance, but so far there was none.

This is a good thing! It seems the community wants things to change too.

How can you help?

If you know somebody developing applications in their own repository, try to convince them to move their packages into Extras(-devel). Please edit the wiki page to reflect the status of each repository.

With the help of a few people, I think we can get number of repositories in the list down quickly!

Visible results

When looking at the Gronmayer listing, you can see that more and more repositories are being removed and end up as: 'Repository is offline'.

Talk: Reducing number of external repositories

At the Maemo Summit, I had a talk about the Extras repositories and the plans for the future. The slides can be found on Slideshare: The huge number of external repositories makes it increasingly hard to have a flawless experience for the user when it comes to package selection and installation. The proplems we currently face is:

• Users are unable to easily find packages
• Users experience conflicts between repositories
• Unable to do quality testing on huge amount of repositories
• maemo.nokia.com – Is not able to hand pick packages from external repositories
  

One of the many things announced by Nokia was the creation of maemo.nokia.com, where the best community made applications will be featured. I guess there will be more posts from Nokia on that topic later.

Back to the external repositories problem:
We started to retrieve all source packages from all know repositories found on Gronmayer. These packages are fed to the autobuilder to see if they would build. The status page looks like this:

Our plan to reduce the number of external repositories:

• Build all source packages available in external repositories
• Show status of builds
  
• Try to discover missing sources (a lot of packages have no source available in the repo)
  
• Help developers to fix build problems
• Convince developers to move their packages into Extras
• Convince teams inside Nokia to do the same
  

We hope to get visible results for this effort. Help with this effort would be very appreciated. Please try to convince developers to move their packages into Extras, when they haven't done so yet.

Together with Dave Neary, I did another talk. This one was about the history of the Maemo community and the changes we went through in the last few months. The slides for this talk are also available:

maemo.org/downloads automatic updates from Extras

The maemo.org downloads section now automatically picks up updated versions from the Maemo Extras repository. The 'Fresh' list will show the applications that were recently uploaded or promoted to Extras. Developers used to need to update their application entry themselves. By doing the updating automatically, users should not see outdated information about applications.

For the automatic update to work your application needs to be:

1. Available in Maemo Extras
2. Available in the maemo.org downloads section where the 'Project ID' equals the name of your debian package.

Package updates are fetched from the most recent repository for each OS we support. Diablo for OS2008, Bora for OS2007 and gregale for OS2006.

One enhancement I would like to add is automatically update the 'Changes in latest version' field for the entry in downloads. I would like comments from the community on how developers should supply this information.

One option would be to fetch it from the changelog. Problems here are that there aren't many packages using a changelog at the moment and we would need to filter out the real changes from the packaging revision updates.

Another option would be to let the developer enter this data while promoting the package to extras. We could add this step to the promotion interface.

Comments are appreciated.

Application in Extras-Devel OK? Promote it!

Now that we have the autobuilder in place for Diablo, it is a good time to talk about how to get your package from Extras-Devel into the Maemo Extras repository.

Before a package will end up in Extras and is installable for end-users on their device, it will go through a few steps:

1. source package uploaded to autobuilder incoming queue
2. autobuilder builds package and moves it into the incoming queue from Extras-Devel
3. queuemanager for Extras-Devel will put the package in the Extras-Devel repository
4. developer checks packages from Extras-Devel and if the package is OK:
5. promote the package to Extras using the Promoter.

Step 5 is the step where you can use the Promoter to promote your package. Make sure you test your application while it is in Extras-Devel, so you don't promote a broken package. After promotion and a bit of patience, your package will show up in Extras and everybody will be able to download it.

We have two Promoters is place:

• Diablo Promoter
• Chinook Promoter
  

The Promoter is a community project on garage.maemo.org. The code can be found in the svn repository. If you have any suggestions on how to improve the interface or would like to add functionality, please propose and discuss it on the maemo-developers mailinglist.

We are still working on documenting Extras and Uploading to extras in the wiki and of course work towards The Big Plan. Feel free to edit the wiki and improve the articles, this is a community project.

Let's work together to get more applications available in Maemo Extras!

Autobuilder for maemo extras repository part 2

Some time has passed since we first announced the maemo autobuilder for the extras repositories. Some people have tested it and we got a little bit of feedback. Not as much as we hoped, but I'm sure that is going to get better shortly.

Ed has been working on making the autobuilder more user-friendly. You will now receive a status message per mail when your package has been processed. If there were any errors (md5 sum failed, files missing, wrong pgp key or package not signed), you will find that out in the email.

Some benefits of using the maemo autobuilder:

• Source packages always available in the repository
• i386 packages are automatically added to the repository, so you can use them in the SDK.
• Prevent obviously broken packages from entering the repositories.
  

I have been improving the assistant by adding more checking and fixing more bugs. It turned out that not everybody was able to request rights to upload packages to the repository. Sorry about that!

I would like to ask all developers to try out the autobuilder and assistant, so we can be in a good shape before Diablo gets released. We can only move forward if you get involved!

Feel free to contact me if you need any help or information.

Autobuilder for extras repository public beta

A while ago we discussed the idea of an autobuilder for the extras repository. We have been working on creating such an autobuilder and have been testing it in private. As a result we now think it is time to do a tests with a larger group and make it publicly known. Please give it a try and tell us your results.

- What does the autobuilder do?

The autobuilder takes a source package from the incoming queue and tries to build it in a fresh environment. The builder fetches all dependencies from the extras-devel repository. If it can't find the dependency in extras-devel, it will fail and send a mail to the extras-cauldron-builds list.

If there are no problems with the package, the builder can create armel, i386 and source packages. Those will be put in the extras-devel repository after a successful build.

Instructions for the builder can be found at here.

The builder only handles building one package at a time. If you have dependencies that are not present in the extras-devel repository, please upload these first.

- web-based assistant

We have also created a web-based assistant to help you with requesting rights to upload and creating/uploading of source packages. You can upload packages to the builder with either dput or the assistant.

- How do I get my package into extras?

After a successful build a package will appear in the extras-devel repository. You can move your packages from extras-devel to extras with the promotion interface. Instructions for the promotion interface can be found here.

We would like to invite all developers to take a look at the autobuilder and try it out. Please discuss problems and feature requests on the maemo-developers list.

More information about our effort can be found at the extras-cauldron website.
