Elektra serves as a universal and secure framework to access configuration settings in a global, hierarchical key database. For more information, visit https://libelektra.org.
This is by far the largest release in Elektra's history. In 2813 commits, 19 authors changed 1714 files with 92462 insertions(+) and 21532 deletions(-). The highlights are:
Unfortunately this release was delayed. The reason for the delay is that our community server (build server, web site,...) was compromised and we needed to reinstall everything from scratch.
We took advantage of the situation, and reinstalled everything properly managed by puppet-libelektra. With puppet-libelektra, you can directly set keys, specifications (validations), and even mount new configuration files from within Puppet.
Our community server is now completely managed by libelektra.
Thanks to Bernhard Denner, for rescuing us from the difficult situation, especially for the sprint shortly before the release.
As already already announced in December 2016 we completely reimplemented our website. Now all our websites are available via https. This release is the first one that includes the source code of the website and its snippet sharing functionality.
The backend for this snippet sharing website uses Elektra itself: both for its configuration and for the configuration snippets.
Thanks again to Marvin Mall for the awesome website.
The Ruby binding, created by Bernhard Denner, was greatly improved and now includes libtools bindings. It is the first binding that goes beyond Elektra's main API. Bernhard Denner also added many examples that demonstrate how you can take advantage of the Ruby bindings.
Armin Wurzinger created a new binding for the functional language Haskell. He also added support for Haskell plugins. Due to generic CMake and C Code, plugins can be written exclusively in Haskell, without any glue code. Several Haskell examples already exist. The Haskell support is currently experimental.
René Schwaiger added completion support for Fish
in this release. We also extended our support for other shells: The new
kdb complete suggests how to complete an Elektra path. It considers
mountpoints and also takes bookmarks into account. Thanks to Armin
Wurzinger for creating this useful utility. Our Zsh and fish completions
already take advantage of
kdb complete. Thanks to Sebastian Bachmann
for taking the time to update the
See plugin overview to get an overview of the ever-growing number of plugins.
The yamlcpp plugin and camel plugin add first support for YAML.
The mini plugin is yet another minimal INI plugin.
Thanks to René Schwaiger.
The date plugin supports validation of dates according to three standards:
The multifile plugin
allows us to integrate many configuration files via globbing with
a single mount command. It supports
.d configuration directories
as often used today.
The file plugin interprets the content of a file as configuration value.
The ipaddr plugin
adds support for IP address validation on systems that do not
Thanks to Thomas Waser for creating these useful plugins.
The xerces plugin supplants the xmltool plugin and allows us to use XML files not following a specific schemata. Attributes are mapped to Elektra's metadata, multiple keys with the same names are mapped to arrays.
Thanks to Armin Wurzinger.
The documentation was greatly improved within this release.
We added even more functionality, which could not make it to the highlights:
kdb rmmeta, thanks to Bernhard Denner
gpg/keywas renamed to
fcrypt/tmpdirallows you to specify the output directory of
-mM), thanks to Armin Wurzinger.
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).
explicit to some C++ constructors in libtools and internally moved
some typedefs. ModulesPluginDatabase now has protected members (instead
of private). This might break code in special cases, but should not affect binary
compatibility. As always we tested for binary compatibility.
This time we had to revert some changes to keep libelektra-tools
These notes are of interest for people maintaining packages of Elektra:
RPATH, remove old policies, thanks to René Schwaiger
BUILD_DOCSETto build DocSet, thanks to René Schwaiger
OPMPHMpreparation work, thanks to Kurt Micheli For this release, please keep
ENABLE_OPTIMIZATIONSturned off. Currently the flag increases memory usage, without being faster.
TARGET_TOOL_DATA_FOLDERfor installation of tool data (for website-backend and website-frontend)
The following files are new:
libelektra-invoke(needed by plugins: curlget, gitresolver, dini, blockresolver, multifile)
The following files were removed:
The following files were renamed:
In the Debian branch of the git repo, we now build upon the work of Pino Toscano. The branch allows building Debian packages of the release for Debian Stretch and Jessie.
Thanks to Pino Toscano for the high-quality packages.
These notes are of interest for people developing Elektra:
ELEKTRA_NOT_NULLis an assertion against null pointers
ELEKTRA_MALLOC_ERRORsets an error when allocation failed
ELEKTRA_STRINGIFYto quote a macro value
ELEKTRA_PLUGIN_STATUS_NO_UPDATEfor return values of plugins.
ELEKTRA_STRINGIFYused throughout, thanks to René Schwaiger
generateKeySetto randomly generate large key sets
ELEKTRA_PLUGIN_EXPORTaccepts macro as argument
print_resultto unify test output, thanks to René Schwaiger
validateKeyas preparation for type plugin
Various other changes happened in the code repository:
kdbtools to print errors on crashes, use
editoris not found. René Schwaiger fixed preposition and format of the messages.
ronnnow always uses UTF-8 as encoded and is no longer required as essential dependency to get man pages, thanks to René Schwaiger
In this release we had a focus on quality improvements:
Many problems were resolved with the following fixes:
kdb file: never print errors, thanks to René Schwaiger
kdb mount-openiccIt protects against message floods in large configuration files, thanks to Kai-Uwe Behrmann for reporting
kdb: fix memleak when listing plugins
kdb mv: fail without keys also in recurse mode
