We are happy to announce that there will be a talk about Elektra in one of the main tracks of Fosdem 2018:
And a second talk in the Config Management DevRoom:
See you in Brussels at 3 and 4 February 2018!
I will also be present in the Config Management Camp directly after Fosdem in Gent.
I am proud to release a book with the title "Context-aware Configuration" describing:
The Fosdem talk will cover some highlights from the book.
A huge thanks to everyone involved in the questionnaire survey, without you we would not have been able to collect all the information that led to the requirements for Elektra.
The LaTeX sources are available here and the compiled book can be downloaded from here.
crypto are now considered stable. They are no longer tagged as
crypto encrypts individual values within configuration files,
fcrypt encrypts and/or signs the whole configuration file.
For this release Peter Nirschl prepared a demo showing Elektra's cryptographic abilities:
Thanks to Peter Nirschl for this great work!
We plan to switch to INI as default storage instead of Elektra's infamous internal dump format.
As preparation work we implemented the
dini plugin which transparently
dump files to
ini files on any write attempt.
Furthermore, we fixed most of the INI bugs which blocked INI to be the
Due to this progress we will likely switch to INI as default starting
with the next release. If you want to, you can switch now by compiling
Or simply switch for your installation with:
sudo kdb change-default-storage dini
If you are already using
ini as default, changing to
dinialways checks if a file uses the
dumpformat, unless the
dumpplugin is not installed.
NOTE: INI (dini) was not completely ready for 0.8.21 thus we kept
diniis currently an experimental plugin.
We added even more functionality, which could not make it to the highlights:
kdb rmnow supports
-fto ignore non-existing keys
%as profile name to disable reading from any profile
The new function
int elektraArrayDecName (Key * key);
decreases the index of an array element by one. It can be used to reverse the effect of

We improved the documentation in the following ways:
jniplugin. The ReadMe now also contains information about the Java prerequisites of the
jniplugin on Debian Stretch.
jenkins build all pleaseand
jenkins build doc pleasewere documented thanks to René Schwaiger
As always, the ABI and API of kdb.h is fully compatible, i.e. programs compiled against an older 0.8 version of Elektra will continue to work (ABI) and you will be able to recompile programs without errors (API).
All unit tests of 0.8.20 run successfully with Elektra 0.8.21. There are, however, some additions and changes in rarely used interfaces:
kdbinvoke.hinterface: make structure private and complete API
kdbopmphm.hgot nearly rewritten
These notes are of interest for people maintaining packages of Elektra:
intercept-fsis now marked more clearly as experimental
jniplugin is again experimental because it does not work with some Java systems. For the
luaplugin there are also problems with some Lua systems.
These notes are of interest for people developing Elektra:

The Order Preserving Minimal Perfect Hash Map (OPMPHM) is ready to extend
ksLookup. The implementation of the randomized Las Vegas hash map
algorithm is in a final stage and the heuristic functions that ensure time and space optimality are backed up by benchmarks.
Thanks to Kurt Micheli, the next release will include the OPMPHM!
