Notifications

Elektra's notification feature which allows applications to keep persistent configuration settings in sync with the key database and other applications was greatly improved with this release:

KDE Workshop

At Akademy 2018 we had a successful Config Workshop.

We generally agreed that misconfiguration is important and the situation in FLOSS needs to improve. We discussed how Elektra can be used in KDE and came up with the idea that KConfig could be moved to a Elektra plugin. Then KConfig could be patched to use Elektra instead. This would lead to the situation that KDE users would have the same user experience with the advantages of Elektra, like:

Type System Prototype

Elektra supports specifying the semantics of keys via metakeys in the spec namespace. An example is the metakey check/range which can be used to specify that a key only holds numbers in a given range. Another metakey is check/enum which only allows specific keywords to be the content of a key. Up to now these semantics are only being checked at runtime. Therefore a type system was developed to be able to check configuration specifications statically. As an example, it would detect when one accidentally adds both a range and an enum check if their possible contents are not compatible with each other.

The type system is available as a plugin that gets mounted along with a configuration specification into the spec namespace. Furthermore we include a set of type definitions for commonly used metakeys such as check/range, check/enum, check/validation, fallback or override.

Chef Cookbook

Next to the Puppet Resource Type we now also prepared a Chef Cookbook which allows us to use Elektra from within Chef.

For example, to set mount a configuration file, you can use:

kdbmount 'system/hosts' do
    file '/etc/hosts'
    plugins 'hosts'
    action :create
end

And to add an hosts entry, you can use:

kdbset '/hosts/ipv4/showthatitworks' do
    namespace 'system'
    value '127.0.0.33'
    action :create
end

Note that currently kdb is invoked and Elektra needs to be installed for managed systems.

Thanks to Michael Zronek and Vanessa Kos.
