bookmark_borderMaintaina Horde: Fourth Of July Additions

I packaged some more exotic horde apps and libraries for use with the composer installer and the FRAMEWORK_6_0 codebase. This was mostly formal conversion work, no actual testing was done. Some of these items might not even be very useful to most administrators. Nevertheless, I want to close the gap between what is available in the horde git-tools install and what can be installed through the horde installer plugin for composer.

These apps are now available:

  • refactor (refactoring utility)
  • trean (bookmarks)
  • ulaform (Forms app)
  • sesha (H4ish inventory app)
  • skeleton (template application)
  • sam (Spam Assassin Integration app)
  • operator (phone call details reader)
  • pastie (simple H4ish pastebin app)

The libraries were previously not available for H6 and now have seen their alpha release:

  • horde/thrift
  • horde/service_urlshortener
  • horde/service_vimeo
  • horde/service_facebook
  • horde/service_twitter
  • horde/scribe
  • horde/reflection
  • horde/pgp
  • horde/rampage
  • horde/oauth
  • horde/kolab_resource
  • horde/pdf
  • horde/lens
  • horde/openxchange
  • horde/mongo
  • horde/memcache

I wish you all a joyful fourth of july.

There are still some items missing, including the Klutz cartoon reader app and some Kolab related libraries.

bookmark_borderComposer Installer gets Horde Themes

A while back I added theme package support to the composer installer for horde (horde-installer-plugin). There are some Horde themes or theme customisations available out there, but they come as zip files you have to manually deploy to the right directories, often spanning multiple apps.

The installer recognizes themes and generates appropriate symlinks in the /web dir to make them available.
You can review maintaina-com/theme-hochschule as a template theme. The hochschule theme is more or less a clone of the standard horde theme, but I might add some tweaks at some point as the user of that themes requires it. Themes are registered into a json file to facilitate operations like regenerating the link dir independent of composer actions, but this has not yet been implemented.

The installer handles the main horde theme in the horde/ sub directory and any app specific additions to the theme in the respective folder. In theory, you could also divide a theme into multiple packages, for example a “theme-foo” main package and a “theme-foo-kronolith” package for calendar specific additions. I did not yet complete support for this style as I currently do not need it. I see the use case though as I take care of some unpublished horde apps and might require it one day.

If you happen to have created a horde4/5 theme which might be interesting to the general public, I am glad to help you adopt it into a package for the H6 composer installer.

bookmark_borderNo more master branch in maintaina horde

I am changing the default branch in all maintaina-com/ horde repos to be the FRAMEWORK_6_0 branch. In a separate next step, the master branch on these repos will be removed.

This is not due to any semantic discussion of technical terms like “master”. I am simply acknowledging reality. At the moment I cannot hope to get all those changes merged into horde’s proper master branches. I do incorporate their advances into maintaina but it is not going to the tight feedback loop I would wish to have.

I have no use for a branch pretending to be something different than or beyond the FRAMEWORK_6_0 venture. I had README’s in all those master branches warning against using them. It is way better to simply get rid of them now.

bookmark_borderHorde/Rdo ORM: PSR-4 and BC Breaks

Summary: Horde/Rdo ORM got upgraded for Namespaces. User code conversion is straight-forward. Backward Compatibility is limited.

If you ever wondered, RDO stands for Rampage Data Objects. This has been on my list for quite long, but it took some time to get it right. The horde/rdo library is horde’s Object Relational Mapping (ORM) solution. It allows you to store objects into sql databases or retrieve them without writing SQL. Originally, it has been written by Chuck Hagenbuch way back in the PHP 4 days and I have been a heavy user for years. If you know Laravel’s Eloquent, Doctrine, Hibernate, ActiveRecord, nHydrate or Dapper, this one is Chuck’s “as light as possible” implementation of the concept. Colleagues from B1 Systems have been users and contributors over the years. However, it has long been time to rethink Rdo in the light of newer capabilities of PHP 7.4 or even PHP 8. This time is now.

But you should not fear upgrading. First, the library still keeps the unnamespaced PSR-0 code, at least for the time being. Second, there is a straight-forward upgrade path for existing users.

Horde_Rdo_Base -> Horde\Rdo\Base
Horde_Rdo_Mapper -> Horde\Rdo\BaseMapper
Horde_Rdo_Factory -> Horde\Rdo\Factory
Horde_Rdo_List -> Horde\Rdo\DefaultList
Horde_Rdo_Iterator -> Horde\Rdo\DefaultIterator
Horde_Rdo_Query -> Horde\Rdo\DefaultQuery
Horde_Rdo_Exception -> Horde\Rdo\RdoException
Horde_Rdo:: -> Horde\Rdo\Constants::

It’s about as easy as it looks. Converting an application took me a few minutes. You might have noticed the names do not exactly match. Some names were not practical to simply turn into namespaced classes. In other cases, I turned class names into interface names. I found myself implementing the same enhancements over and over in multiple projects and I found myself wishing there was an easy way to do some others.

Less Boilerplate Mappers and Entities

Rdo is much more fun than some other ORMs as it comes with very little configuration. The library autodetects properties from the table columns. Datetime fields are automatically cast to Horde_Date objects. By default, Rdo tries for a convention over configuration approach for mapping table names, mappers, entities etc. Unfortunately, for most of my projects, that default does not fit too well to the class structure and file layout I choose. But still, implementing a new pair of mappers and entities takes two files and only two or three settings I ever need to think about.

Most often, subclassing the base mapper and the base entity is the right thing to do. But sometimes, you do not really care. If all you ever do to your entity is call ->toArray() and serialize it to json, you would be served very well by a generic entity instead. This is something on my list. I would even go one step further: If all you are changing to a mapper is subclassing and telling it the name of its database table and entity class, why subclass at all? Yes, I would want to turn the optional Factory class into something smarter. It will give you your mapper, be it an instance of the generic mapper with the right table name or something very customized.

Custom List Objects

Rdo queries always return a Horde\Rdo\List. This is a good default implementation and it makes common tasks easy. However, there are situations where you want your list of entities to be specific to an entity type or maybe a subclass of some base list class completely external to Rdo. Maybe you want to manipulate a list or merge results from two different queries.

Custom Entities
Sometimes the default entity implementation does not serve you well. There’s a range of things you would want.
– You want to inherit from a base class to attach behavior to your data. So you attach an interface and a trait to that foreign class to make it Rdo aware.
– You want to implement your own behaviour altogether
– You want Rdo to implement a proper repository with strongly encapsulated, less chatty domain objects. Rdo should provide a mechanism to produce those objects for you rather than having you cast or wrap Rdo\Base objects into your actual models. But it should not force you to think about such concepts before you really need them.

NoSql backends
Remember the name Rampage Data Objects? Rdo is mostly about mapping data to objects. It’s not about autogenerating the smartest SQL for the most obscure use cases. But once you have your prototype version ready, your first feedback comes in, you think about new features – and suddenly you want to support a new backend for some of your domain objects. Be it a NoSql database, a key/value store, a limited scope within a directory like LDAP or even a REST service. In a traditional horde application, you would wrap Rdo into a Driver called Driver/Rdo or Driver/Sql and implement a different backend. But what if you do not want to flip all your data to the new backend? Only the shopping list should go to the nosql backend but not the customers or the product inventory? You end up implementing individual drivers with individual backends. But you used Rdo’s relations feature … things get messy.

To achieve these capabilities, I want to make the Mapper less dominant. The formerly optional Factory gets promoted to take care of managing the right mappers, entities, backends, list types. This is what these interfaces are for. Mappers should mostly take care of mapping between an object class and a plain data format. Currently the mapper and query do too much, tightly coupled with the single mandatory list type. This will change.

Rampage Data Objects provides out of the box defaults for easy and common use cases. It gets you started really quick. We will add the capabilities needed when your application is maturing and your use cases get more demanding. This will be fun.

Backward Compatibility Breaks
The Horde\Rdo\Base* classes and their return types will be your best bet for backward compatibility. If you don’t try to use entities and mappers for side effects, you will be very safe. Factory’s constructor will change very soon. Factory should best be created from a Dependency Injector. Mappers should be created from Factory.

You should not rely on mappers exposing adapter or factory for creating other objects. Also, trying to manipulate sql session modes or transactions through Rdo’s adapter is not a good idea.

bookmark_borderWhy extending PHPUnit might be wrong

Over the last few months, I spent a lot of cold winter evening hours looking into porting ancient PHPUnit 4.x test suites over to PHPUnit 9.x. The test suites, you guessed it, belong to the Horde framework. Horde actually does not just use phpunit but wraps it into its own testing library horde/test. The full details are explained on the wiki. Horde provides multiple ways to actually run the unit tests, either through its components helper or through AllTests.php or through calling individual tests with phpunit. While horde/test adds value and allows simplifying some test scenarios, it also has its own problems.

I’m not saying it didn’t make sense back when this was built. The original alpha release of horde/test dates back to 2011. PHP 5.4 was not yet released, composer would see its initial release in 2012, PEAR was slowly getting old and PEAR2 was not yet officially a dead cow. It was a totally different ecosystem back then. However, times have changed.

As of 2021, phpunit has evolved into a relatively fast moving target and while its primary author Sebastian Bergmann does not break backward compatibility for the sake of it, he is not shy of doing it either. Some parts of phpunit which are relevant for integration may become unavailable in the next major release. Some of PHPUnit’s core classes are clearly marked as internal.

The Horde Test library adds some mandatory boilerplate to phpunit: Each library and app has its own mandatory bootstrap.php file calling into the test library’s bootstrap class and may have an additional autoload file. Also, a test suite should come with an AllTests.php file calling into the test package’s AllTests class and in turn using Horde_Test_AllTests_TestRunner – which extends PHPUnit\Runner\BaseTestRunner but wait…

https://github.com/sebastianbergmann/phpunit/blob/9.5/src/Runner/BaseTestRunner.php

/**
 * @internal This class is not covered by the backward compatibility promise for PHPUnit
 */
abstract class BaseTestRunner

Trouble ahead, maybe. I am not joking. The master branch which will become PHPUnit 10 does not even have that file. We can find a solution for that, sure. But maybe we should not. As of 2021, the horde/test suite contains valuable helpers and extensions to PHPUnit, but none of these really need to hook into phpunit’s core that deep anymore.

Let’s look into different issues covered by that code.

Autoloading and dependency setup

Back in 2011 it made sense to have some glue which combines autoloading with Horde’s and PEAR’s notions of how things should be organized in a file system. That is no longer a core concern. Everybody and his dog use composer and composer’s autoloader and either do PSR-0 or PSR-4 autoloading schemes. Horde 6 will be delivered via composer, does – optionally, partially – break with some older ideas of organisation, brings some PSR-4 code and a lot of PSR-0 code. In short, there is very limited need for a custom autoloading scheme. The test suite should just rely on some autoloading being setup, by whoever or whatever. It should not address this concern beyond the means already provided by phpunit itself. Code should be accessed through checking if class names are either present or loadable, not by assuming some files are in some location. Of course, this is a little simplified – at its core, all autoloading depends on something being in some wellknown location. We should simply rely on the default solution until it is not possible for a specific case – and then address that. Even if we accept the notion of a vendor dir and an autoload file in vendor/autoload.php, we could provision it via horde/components or horde/git-tools or some horde/test utility for the rare cases where just using composer would not be appropriate.

Setting up complex test cases

Tests are supposed to be simple. They should focus on one unit under test and keep as much of the ecosystem as possible out of the picture. Dependencies should be stubbed or mocked. Databases and I/O, especially network traffic, should be substituted. A majority of test cases should be modeled with just the library’s own code and PHPUnit’s mocking facilities, maybe depending on some interfaces from some dependency.

But sometimes it’s not so easy. Sometimes the unit under test actually IS code interfacing with databases and their subtle differences. Sometimes the code needs to interact with a non-trivial amount of configuration and dependencies. Especially code which interacts with the framework’s core services or which couples the application’s subsystems may not be easy to mock. It makes sense to provide a simplified pretend environment for such test subjects. But that should be opt-in on a case by case basis. It should not be a mandatory tie-in of additional code and boilerplate for even the most trivial test cases.

Integration with tools

horde/components and some other tools wrap phpunit and other utilities. But as the ecosystem changes, the benefits are shrinking. Github Actions and Gitlab CI have become popular platforms with many ready-made CI tools available to use. It is no longer necessary to run your own Hudson or Jenkins and build your own automation frameworks. While it is still nice to have a short way to run a test suite including dead code and copy/paste detection, coding style fixers etc without the need to check anything into the SCM or even create a commit, there’s little incentive for maintaining a deep integration into your own runtime code. In the end, all testing and quality assurance automation aims to make you deliver safe, stable code as fast as possible. Spending ours writing automated tests makes sense and may safe you from hours of debugging and frustration. Spending hours writing or fixing a deep integration into some test tool which simply does not want to be integrated? Less so. It should be kept to a minimum. There’s a reason why the preferred delivery of some of these tools is not composer but phar.

What can you do?

So what would a new test toolchain look like? Unit tests and even integration tests should rely on a default, external autoloading solution. In the absense of configuration, this should be vendor/autoload.php, however it is delivered.
Unit tests should by default just run off PHPUnit and the library’s code. Maybe it makes sense to provide the most widespread interfaces without actually having to install their backing code. Why not, as long as it does not create manual effort. Any framework-specific recurring need should be addressed by opt-in code provided as traits or helper classes, available through default development-time autoloading sources. Fringe tests relying on specific infrastructure should skip without failing. Configurable tests should run out of the box in a useful default configuration if it makes sense. These changes can be created in an incremental, opt-in fashion with very limited BC breaks. This is good as nobody has time to waste on large scale transformation. Remember, it’s all about your code, the tests are just a useful tool.

bookmark_borderTurba Addressbook (II) – Architecture

Welcome back to our mini series on Turba.

Part I covered all the features and integrations provided by Turba.
Part II gives a dive into implementation, code structure etc.
Part III will consist of proposals for a changed architecture.

In the first chapter we looked at Turba’s features, APIs, Protocols. In the current installment, I want to present the concepts and structure of the code.

Turba is among the oldest horde applications. As such, it contains parts from various stages of Horde’s development.
Basically, it’s a layered architecture, but not fully fleshed-out or fully separated.

  • Presentation layer
  • Application Logic Layer
  • Storage/Backend layer

This is plugged together with some framework-provided integration points

  • with the sync services and inter-app API, RPC
  • with the portal/blocks service
  • with the Backup API
  • with the Content Tagger

Presentation Layer.

Turba provides both a desktop UI and a mobile UI. The following is mostly about the desktop UI. Blog de culturismo total fitness de lee hayward: debes probar estos entrenamientos musculares híbridos primobolan depot inicio – culturismo femenino y control de la natalidad, entrenamientos de culturismo femenino youtube – la casa de juegos del kama sutra negro.

Turba’s UI is organized into client pages rather than using a controller/route approach. This means, user visible URLs include files with a .php suffix.
The client pages build the UI, but are also API endpoints in a very traditional sense, catch interaction from forms or buttons as get variables and trigger actions in the backend
A representative example:

https://github.com/horde/turba/blob/master/search.php#L155
try {
$share = Turba::createShare(strval(new Horde_Support_Randomid()), $params);
$vid = $share->getName();
} catch (Horde_Share_Exception $e) {
$notification->push(sprintf(_("There was a problem creating the virtual address book: %s"), $e->getMessage()), 'horde.error');
Horde::url('search.php', true)->redirect();
}

Typically the top part of each client page is initializing the application, catching request and environment/session variables, setting up the business objects.
The middle part usually orchestrates actions depending on present or missing parameter scenarios.

The lower part will actually output the Horde Topbar, utility javascript, and the actual page content.

A rather extreme example is the data import/export part: https://github.com/horde/turba/blob/master/data.php
It contains mappings, attribute filtering, a longer cascade of if’s and switch statements and after about 360 lines, the actual UI logic starts.

This might sound messier than it really is. Actual functionality is mostly factored out into separate classes and the UI uses both some View classes and a form library.
Turba’s UI is heavy in forms and tables for the very reason that editing and displaying a highly configurable addressbook with hundreds of fields of data is
very crud-like by nature.

The Turba UI uses three types of helpers to compose the UI:

  • View classes
  • The Forms library
  • HTML templates with PHP snippets

View Classes

The View classes are very similar to the horde/view library and replicate some of its functionality, but are not using or inheriting from it.

Forms Library

Turba is a prominent user of the horde/forms library.
This utility allows to dynamically compose forms or multiple fields, check for internal/formal validity of entered values, missing mandatory values, etc.
It couples both a readonly and editable representation with a lot of processing logic.
Forms relies mostly on server-generated HTML with small parts of javascript injected for usability improvements.
The JavaScript snippets may utilize PrototypeJs and Scriptaculous, two formerly popular mainstream libraries.

Templates

The HTML templates provide most of the actual presentation apart from the forms – though they also provide some HTML forms to drive interaction.

Mobile View

Turba provides a read-only, touch friendly mobile phone presentation based on jQuery Mobile. This is completely separate from the rest of the turba UI.

Application Logic Layer and Backend Layer.

These two layers are closely tied together so it makes sense to discuss them as one.
From a problem domain perspective, it would make sense to expect these items:

  • Multiple addressbook sources or backends. These are individual configurations using drivers. Multiple sources on the same ldap driver can represent different directories or different views on one.
  • Addressbooks
  • Addressbook entries or contacts
  • Groups which are both entries and contain entries.

Turba’s logic layer consists of

  • Representations of actual addressbook entries via the Object and Object_Group classes.
  • A collection of reusable static functions in the Turba class.
  • Parts of the base backend driver.
  • Exporters/Importers for formats like LDIF and vCard.
  • specialised forms which deal both with presentation and state transformations.

Turba Objects and Groups are the common ground here. The objects glue together the actual data from the driver, files from VFS, permissions managed by the driver, the object’s change history and tags in the tagger app.
Groups are the only subtypes of Objects or Entries. Other subtypes suggested by the vcard standard like organisations or locations get no special treatment. Groups act as virtual addressbooks or views on addressbook data.
Turba’s groups only work with turba-accessible contacts. They cannot reference external contacts from other sources.

The addressbooks don’t really show up as entity objects. They are arrays of passive data managed by different parties.
This makes part of the logic a little hard to reason about and to setup unit tests.

A lot of Turba’s logic is data transformation. Backends have a native representation of data as SQL columns, LDAP objects, etc… as well as possibly native key names.
A person’s name may be a column “object_lastname” in one backend, but an attribute “givenName” in another one.

This is complicated by a highly configurable list of fields each backend can hold.
A driver transforms these native formats into a uniform format, transform date strings into date objects, handle blobs etc…
Both the driver dependent format and the “turba” format are hashes. It is up to the driver to actually generate a list object containing individual addressbook entry objects.

Another functionality delegated to the driver is deriving TimeObjects from addressbook data. TimeObjects are really not objects but hashes, representing anniversaries or birthdays.

Permission management in turba is using three distinct approaches:

  • The permission system allows restricting who can view or edit a certain addressbook
  • One addressbook source, usually the SQL db, can be configured as using the Shares system. In this case, the user can delegate access to addressbooks to other users or groups or make them world readable
  • The backing technology can restrict the user further. For example, the LDAP driver can be used to either bind using a service credential or using the user’s credential. Different users could have completely different data presented based on LDAP ACLs.

In the next article of this series, I am going to propose some modernisation approaches for Turba and discuss how they bring benefits in maintaining or extending the software vs being a tedious refactoring exercise.

bookmark_borderTurba Addressbook (I) – Features

I Turba Feature Overview

This will be the first part of a short series of articles exploring the Turba application and its architecture.
Part I covers all the features and integrations provided by Turba.
Part II will look into implementation, code structure etc.
Part III will consist of proposals for a changed architecture.

Turba is the addressbook application of the Horde Groupware Suite. It offers access to addressbook information via various means and protocols.

These addressbooks can be of quite different nature:

  • Readonly or Read/Write addressbooks stored in a backing system (LDAP, SQL databases, Kolab)
  • Virtual addressbooks derived from Horde Groups or from favourite addresses data out of the IMP mail program or any other provider implementing the appropriate API.
  • Addressbooks representing contact groups stored in addressbooks
  • There is also a pseudo backing store through the Preferences API, which in turn needs some backing store.

Depending on the type of addressbook and backing system, different features are available

  • browsing
  • searching for entries matching criteria
  • user-controlled sharing addressbooks with others
  • administrative reading or writing of data without the user being logged in

Administrators are allowed to customize the fields and presentation of the addressbooks presented to the user.
They may add custom fields relevant for their site like a student ID number or an ssh public key.
They may remove almost any default field if their LDAP does not expose it or if it’s simply unwanted.

While the primary work model used to be tp browse/search the addressbook or make the addressbook data available in the web interfaces of the calendar and webmail program,
modern users often consume the addressbooks by other methods.

  • Turba allows for syncing addressbooks via the CardDAV protocol into mobile devices or desktop clients like Mozilla Thunderbird.
  • Addressbooks can also be transmitted via Exchange ActiveSync (EAS) or used as a Global Address List (GAL). This allows limited integration with Microsoft Outlook.
  • An older protocol SyncML offers similar, but limited capabilities. It has fallen out of wide spread use since. Turba is still a valid SyncML Server.
  • Addressbooks and contacts are also served via WebDAV as folders and files.
  • Imports/exports to CSV/TSV and LDIF formats, vCard format and some proprietary formats.
  • Addressbook and Contact Reading/Writing is exposed via the Horde Inter-App API and – through this layer – via JSON-RPC and XML-RPC. The RPC layer also has a SOAP interface and an integration driver for phpGroupware / eGroupware though I have no idea if this works with current versions.

The next article in this series will give an overview of the current architecture.

bookmark_borderWhat’s new in Maintaina Horde: Status 3/2021

  • CalDAV and CardDAV now run off SabreDAV 4 rather than SabreDAV 2
  • We now support both the Composer installer versions 1 and 2.
  • Nothing still depends on the PEAR protocol.
  • The Horde Icalendar Library now supports vCard 4. Still, importing/exporting vCard 4 or using it in CardDAV in the addressbook App Turba is not yet done. This requires good test coverage, syncing is not something I’d like to break
  • PHPUnit Tests are being upgraded from PHPUnit 4 to PHPUnit 9.
  • All libraries and groupware-related libraries are now packaged as “alpha” versions from the FRAMEWORK_6_0 branch

bookmark_borderMaintaina Horde: Q&A

There’s sometimes a little confusion about that. Let’s answer common questions.

What is Maintaina Horde?

Horde is a long-living email and groupware solution. It’s free & open source and owned by Horde LLC.
Maintaina Horde is a fork from the official horde repository adding / improving code. It started out as a proof of concept but it went on to become stable and persistent.

Maintaina is not a company. Everything written for this fork is intended to be upstreamed into proper horde as time and quality permit. Maintaina includes both results of paid work hours and free time volunteering, depending on what’s the current job of the persons involved and how Horde belongs into the picture. There’s really little time for any marketing, sorry.

Who runs this for production?

Yes, this is in daily production use. B1 Systems GmbH, the company I work with, is using both the Horde Groupware and the Horde Framework for internal and external customers. They also offer paid development, operations and consulting services. Get it hosted externally, get it set up on premise/in your DC or cloud, consume security upgrades… yeah. You get it.

Can I run your fork for personal or commercial use?
Yes. All the needed parts are released on public github, including ready-to-run daily container builds and a turnkey docker-compose solution. Everything’s free, go ahead.

If you need something stable and reliable on the other hand, there’s more work to do. It’s not advisable to run production setups off bleading edge nightly code. You need to pick and review versions, run quality checks, decide if an update is good for you. That’s work you could do yourself or delegate to some company. Did I mention B1 Systems GmbH?

Will it run my custom app?

We’ve gone through quite some pains to keep everything as backward compatible as possible. If your custom app runs off horde 5.2 or horde master branch, it’s very likely it will run without any code level modification. You may need to craft a composer.json file to get the autoloading right. Another issue may be with code trespassing into other packages’ directory layout and unconditionally include/require’ing any files. These are easy to fix.

Will this code run from a traditional pear or git-tools setup or a distribution package?

Most likely. If you submit PRs addressing problems with that, they’re welcome. It’s just not our priority.

When will the proper Horde 6 be released? Will it contain all the Maintaina enhancements?
I have little say in that. FOSS projects are always short on time and developers. The owners of horde might disagree with some changes. Most likely delays happen because they lack time to review changes for quality. There’s a paypal button on the Horde Website.

I need that feature X …
Open an enhancement request at https://bugs.horde.org if you want to suggest an enhancement.
Or open a pull request on github.com to directly supply a change you developed.
If you need something quickly, ask the companies mentioned for a paid solution, be it a private customisation or a public feature enhancement. However, only Horde LLC has the last word on what goes into their upstream product.

Can I hire you directly?

No. I don’t do freelance work.

bookmark_borderMaintaina Horde: Now on Leap 15.2

I changed the maintaina.com Horde Images to use openSUSE Leap 15.2 instead of openSUSE Tumbleweed as a base. You should not experience any issues but I have not yet tested much. The change was necessary as I had build failures since 2021-02-17 in the github actions CI builds. It’s something about the docker used in ubuntu-latest being too old or github’s security settings being too strict. I did invest some weekend hours, but could not really solve it. I intend to switch back to tumbleweed at some point.

Update July 2021: I can now build tumbleweed-based images again.
