Introduction
OBS can build not only build traditional RPM packages, but it can even build appliances or installation ISO images.
We use this feature in YaST:Head:installer project to build an installation image with the latest YaST (which is not included in Factory yet). This allows as to try new things without worrying to break the installer in Factory or in the upcoming openSUSE distribution.
The Problem
Because the public build service is sometimes quite slow I have deployed a private OBS instance (see the OBS download page) at my workstation.
I found out that product building is relatively slow, even when running in the private instance locally. A quick look revealed that for building ISO image the build service downloads too many packages including source packages, debugsource and debuginfo packages which are not need for our installation ISO image. The amount of the unnecessary packages is several gigabytes even for our small mini installation DVD (which contains packages only for Minimal X pattern, no KDE nor GNOME...).
Focus of the Project
This project is focused on decreasing package download for product ISO image build.
The project should make building ISO images in OBS faster (especially in a private instance linking to the public OBS server), saving disk space and download bandwidth.
Result
I have successfully added kiwi file parsing (to know whether the debuginfo and source packages are needed or not) and skipping debuginfo and source packages into both OBS scheduler (which checks and evaluates dependencies and triggers builds) and worker (which downloads the packages during package/ISO build).
Outcome of the Project
- Significantly decreased amount of downloaded packages, over 7GB (!!) even for our small miniDVD
- This results in faster builds, disk space and network bandwidth savings
- Created a GitHub pull request to include this improvement upstream
- I learned a lot about OBS internals
- And refreshed my perl knowledge ;-)

I have implemented this optimization in my private OBS instance at https://muffin.suse.cz, for building our miniDVD.
In this case it saves over 7GB package download for the ISO image build!!

I have created a GitHub pull request to include this improvement in the next OBS release (and likely in the public instance as well), see https://github.com/openSUSE/open-build-service/pull/426.

There are still possible some more improvements, OBS still downloads some more not needed packages:
- If you build x86_64 only medium also i586 packages will be downloaded although not needed
- It downloads packages from all repositories, if the kiwi file contains more repositories the packages will be downloaded from all of them, but during build kiwi will properly choose only one package (depending on the repository
priorityattribute) - It downloads all binary packages which are build from a source package. For example if your kiwi file only requires e.g. augeas package in the target product ISO then OBS will still download augeas-devel, augeas-devel-32bit, augeas-lenses and augeas-lenses-tests packages.

Create a page with all devel:languages:perl packages and their versions by tinita
Description
Perl projects now live in git: https://src.opensuse.org/perl
It would be useful to have an easy way to check which version of which perl module is in devel:languages:perl. Also we have meta overrides and patches for various modules, and it would be good to have them at a central place, so it is easier to lookup, and we can share with other vendors.
I did some initial data dump here a while ago: https://github.com/perlpunk/cpan-meta
But I never had the time to automate this.
I can also use the data to check if there are necessary updates (currently it uses data from download.opensuse.org, so there is some delay and it depends on building).
Goals
- Have a script that updates a central repository (e.g.
https://src.opensuse.org/perl/_metadata) with metadata by looking at https://src.opensuse.org/perl/_ObsPrj (check if there are any changes from the last run) - Create a HTML page with the list of packages (use Javascript and some table library to make it easily searchable)
Resources
Results
Day 1
- First part of the code which retrieves data from https://src.opensuse.org/perl/_ObsPrj with submodules and creates a YAML and a JSON file.
- Repo: https://github.com/perlpunk/opensuse-perl-meta
- Also a first version of the HTML is live: https://perlpunk.github.io/opensuse-perl-meta/
Day 2
- HTML Page has now links to src.opensuse.org and the date of the last update, plus a short info at the top
- Code is now 100% covered by tests: https://app.codecov.io/gh/perlpunk/opensuse-perl-meta
- I used the modern perl
classfeature, which makes perl classes even nicer and shorter. See example - Tests
- I tried out the mocking feature of the modern Test2::V0 library which provides call tracking. See example
- I tried out comparing data structures with the new Test2::V0 library. It let's you compare parts of the structure with the
likefunction, which only compares the date that is mentioned in the expected data. example
Day 3
- Added various things to the table
- Dependencies column
- Show popup with info for cpanspec, patches and dependencies
- Added last date / commit to the data export.
Plan: With the added date / commit we can now daily check _ObsPrj for changes and only fetch the data for changed packages.

Switch software-o-o to store repomd in a database by hennevogel
Description
The openSUSE Software portal is a web app to explore binary packages of openSUSE distributions. Kind of like an package manager / app store.
https://software.opensuse.org/
This app has been around forever (August 2007) and it's architecture is a bit brittle. It acts as a frontend to the OBS distributions and published binary search APIs, calculates and caches a lot of stuff in memory and needs code changes nearly every openSUSE release to keep up.
As you can imagine, it's a heavy user of the OBS API, especially when caches are cold.
Goals
I want to change the app to cache repomod data in a (postgres) database structure
- Distributions have many Repositories
- Repositories have many Packages
- Packages have many Patches
The UI workflows will be as following
- As an admin I setup Distribution and it's repositories
- As an admin I sync all repositories repomd files into to the database
- As a user I browse a Distribution by category
- As a user I search for Package of a Distribution in it's Repositories
- As a user I extend the search to Package build on OBS for this Distribution
This has a couple of pro's:
- Less traffic on the OBS API as the usual Packages are inside the database
- Easier base to add features to this page. Like comments, ratings, openSUSE specific screenshots etc.
- Separating the Distribution package search from searching through OBS will hopefully make more clear for newbies that enabling extra repositories is kind of dangerous.
And one con:
- You can't search for packages build for foreign distributions with this app anymore (although we could consume their repomd etc. but I doubt we have the audience on an opensuse.org domain...)

Testing and adding GNU/Linux distributions on Uyuni by juliogonzalezgil
Join the Gitter channel! https://gitter.im/uyuni-project/hackweek
Uyuni is a configuration and infrastructure management tool that saves you time and headaches when you have to manage and update tens, hundreds or even thousands of machines. It also manages configuration, can run audits, build image containers, monitor and much more!
Currently there are a few distributions that are completely untested on Uyuni or SUSE Manager (AFAIK) or just not tested since a long time, and could be interesting knowing how hard would be working with them and, if possible, fix whatever is broken.
For newcomers, the easiest distributions are those based on DEB or RPM packages. Distributions with other package formats are doable, but will require adapting the Python and Java code to be able to sync and analyze such packages (and if salt does not support those packages, it will need changes as well). So if you want a distribution with other packages, make sure you are comfortable handling such changes.
No developer experience? No worries! We had non-developers contributors in the past, and we are ready to help as long as you are willing to learn. If you don't want to code at all, you can also help us preparing the documentation after someone else has the initial code ready, or you could also help with testing :-)
The idea is testing Salt (including bootstrapping with bootstrap script) and Salt-ssh clients
To consider that a distribution has basic support, we should cover at least (points 3-6 are to be tested for both salt minions and salt ssh minions):
- Reposync (this will require using spacewalk-common-channels and adding channels to the .ini file)
- Onboarding (salt minion from UI, salt minion from bootstrap scritp, and salt-ssh minion) (this will probably require adding OS to the bootstrap repository creator)
- Package management (install, remove, update...)
- Patching
- Applying any basic salt state (including a formula)
- Salt remote commands
- Bonus point: Java part for product identification, and monitoring enablement
- Bonus point: sumaform enablement (https://github.com/uyuni-project/sumaform)
- Bonus point: Documentation (https://github.com/uyuni-project/uyuni-docs)
- Bonus point: testsuite enablement (https://github.com/uyuni-project/uyuni/tree/master/testsuite)
If something is breaking: we can try to fix it, but the main idea is research how supported it is right now. Beyond that it's up to each project member how much to hack :-)
- If you don't have knowledge about some of the steps: ask the team
- If you still don't know what to do: switch to another distribution and keep testing.
This card is for EVERYONE, not just developers. Seriously! We had people from other teams helping that were not developers, and added support for Debian and new SUSE Linux Enterprise and openSUSE Leap versions :-)

Improvements to osc (especially with regards to the Git workflow) by mcepl
Description
There is plenty of hacking on osc, where we could spent some fun time. I would like to see a solution for https://github.com/openSUSE/osc/issues/2006 (which is sufficiently non-serious, that it could be part of HackWeek project).
