How to submit a fix to a package
The easiest and most convenient way to contribute to Factory is to just submit fixes. If you know why a package does not build or does not work correctly, why not send a fix? If the version of a package is outdated, why not update it? To make this possible for everybody, the openSUSE developers leverage the collaboration features of the Open Build Service for Factory contributions. This means that everyone can branch packages from openSUSE:Factory, do modifications and submit them back; it is as easy as checkers. First, you need to checkout the package with osc.
As you can see, the server created a copy of the package from the correct devel project and placed the result into your home project. Check it out to your local machine to do any changes.
Alternatively, you can use `osc bco` to chain the branch+checkout actions into one command.
Remember to add an entry to the changelog so that it is easy for others to know about your changes.
After you have changed what you wanted to fix and the package builds and works correctly, you can check in your changes to your branch.
Then submit them to the developer of the package for review.
The developer of the package will then get notified about your submission and will review it. We call this BURPing.

How to add a new package to Factory
If you have never created a package before, you may want to visit this tutorial before you begin submitting packages to OBS.
The openSUSE:Factory project requires that every package reside in a so-called development project (devel project and develprj for short), which acts as a feeder project to openSUSE:Factory for your package. The home: namespace is not permitted to act as a develprj for Factory packages.
Just like it is the case for openSUSE:Factory, development projects are overseen by their respective reviewers and/or maintainers, and new package creations from non-maintainers need to be approved. Even though a submit request can create a package, the `osc submitrequest` command acts more like a request to copy, and hence always requires a source location. To truly start from scratch, one has to use the `osc mkpac` command instead. By default, users only have write permissions in their home namespace, which is home:yourname. So then, for example
osc mkpac home:yourname/packagename osc checkout home:yourname/packagename
will create and then checkout a blank package, inside which you can make modifications as desired. Take note that the default repositories that are set up for home:yourname are pointing to the distributions (Leap/Factory/etc.) directly, and not to the develprj—it may become necessary to edit this (`osc prj -e home:yourname`) if you wish to make use of packages or features not yet present in Factory.
Once you have completed your edits to the package, i.e. populating it with a .spec file, source tarball or other ancilliary files, and have verified that the build has successfully completed, the package can then be submitted like before:
osc submitrequest \ -m 'I want to maintain python-cerealizer in Factory and would like to use devel:languages:python as the devel/feeder project.' \ home:yourname/python-cerealizer devel:languages:python
A list of the current devel projects can be found in this list. Find a public list of all projects here. If you cannot find a corresponding topic, you need to use our catchall project devel:openSUSE:Factory. If you have a completely new collection of packages that could form their own devel project, see #How to request a new devel project.
When the devel project has accepted the new package, that package will generally have no additional permissions, which means that only develprj maintainers could edit it later. The maintainer who approves your package creation/update request can add you as a package maintainer — the OBS web interface has a checkbox for them. However, this checkbox is not enabled by default, and it may be overlooked. Based upon the example of python-cerealizer, you can check for assigned permissions by way of
osc meta pkg devel:languages:python/python-cerealizer
If you see your username in a `<person role="maintainer" ...>` line, all is set. If not, you can request edit permissions after the fact using
osc reqms devel:languages:python/python-cerealizer
Whether or not you have edit permissions on the package, you can trigger a submit request of the package to openSUSE:Factory. That submit request should contain a note with information about the package. Preferably, you introduce the package to the opensuse-factory list and point to that introduction in your submitrequest. A good introduction contains information on the state of the upstream project and how maintainable it is and what the purpose of having it in the distribution will be.
osc submitrequest -m 'New package see http://lists.opensuse.org/opensuse-factory/2011-05/msg00018.html ' devel:languages:python/python-cerealizer openSUSE:Factory
How to request a new devel project
Scenario: There is a piece of software that is not in Factory, it is not maintained anywhere in the openSUSE Build Service (except possibly in the home: space), and you want to get it into Factory/Tumbleweed.
First, you need an OBS project somewhere outside of the
home: namespace. In most cases, one of the existing devel projects will be appropriate for your new package. Just submit an SR to the appropriate devel project.
If you need a new devel project, one way to get one is to contact the maintainers of an existing top-level project and ask them to create a subproject for you. If none of the existing namespaces are a good fit, ask the OBS maintainers to create a new project space by opening a bug or writing to firstname.lastname@example.org.
If the project your package ends up in is an existing devel project, you can now submit the package to Factory.
However, if you had to make a new project for your package, there is more work to do. Each package in Factory/Tumbleweed has a "devel package" associated with it. These are the projects in the drop-down menu on top of the openSUSE:Factory project page or list in dashboard container. The location of the devel package (i.e. the project where it lives) determines what the devel project for that package is. In our case, both the package and the project are new: Factory doesn't know about them. When you submit from an project that is not in the list, the submission will be auto-declined.
This appears to be a Catch-22 situation. There is a way out, however, by whitelisting the new project in the Target Project's OSRT:Config attribute utilized by the bot that vets Factory submissions. To do this ask that the project be added to the devel-whitelist space separated list in the config either by asking in #openSUSE-factory or in the opensuse-releaseteam mailing list. Once the project has been added submit requests will not be declined based on source project.
If a package is already in Factory and is merely being moved to a new location, and that new location is not a Factory devel project yet, it can be made into one by issuing a changedevelreq for that package to the new location (after moving the package). If that new location was not yet a devel repo, upon accepting the chgdev, it will become a devel repo and all future submissions from this repo, including all other packages there, will be accepted.
How to become a maintainer of a package in Factory
Just talk to the current developer if you want to help or take over responsibility and be aware of the duties and rights of a Factory maintainer
You determine the current maintainer by accessing build.opensuse.org or with this command:
To get an email-address for contact, use
Apart from just writing to the current maintainer, there are two more options:
- osc requestmaintainership openSUSE:Factory aaa_base
- go to build.opensuse.org, login, then search for the package you're interested in, then "Request role addition".
How to merge a fix for a package in a devel project
The Open Build Service will notify you about new requests via email. You also can also query it for all the new request.
Merging the changes is as simple as accepting the request. Its a good idea to examine the changes first.
And if you like what you see you accept it
How to submit a package to openSUSE:Factory
Once you are satisfied with the state of your package in your devel project, simply submit it to openSUSE:Factory.
If you submit a lot of related packages in a short period, be prepared to equally receive declines. Time has shown that, if there is a problematic change in one package, there is a fair chance the same issue is present in other packages of the mass submit. We would therefore recommend that, if you plan on doing a mass submission, that you split it up into batches, and that the first batch has only on the order of 5–10 packages. Subsequent batches of a mass submit can increase in size linearly.
How to submit a package to a released product
If you want to fix a package in a released distribution, like openSUSE 11.4, you have to do some additional steps. They are described in the package maintenance guidelines.
How to drop a package
Let's assume that we want to drop the oldstuff package from Factory, and that its devel project is devel:openSUSE:Factory. You should first check that no other packages depend on oldstuff in Factory.
If some packages depend on it, you have several options:
- give up and accept to keep oldstuff
- drop those packages first
- change those packages to not depend on oldstuff
Once you have found a solution, just file a drop request for oldstuff in openSUSE:Factory, explaining why you want to drop the package.
When a package is removed from Factory, it is not automatically removed from the devel project. The reason is that the package could still be used outside of Factory, in the devel project for some other reasons. So, depending on your needs, you might want to remove the package from the devel project too.
