The Featureless Linux Library stable version 0.6.4 is released.

This release contains numerous bug fixes and code clean ups. There are also some features implemented as either a solution to a bug or to accommodate changes to a specification. This change also revisits some of the copyrights and further clarifies them.

Adds the following stand alone programs:

  • controller
  • fss_identify
  • iki_read
  • iki_write

Copyrights are now displayed when the programs are passed the +C/++copyright standardized parameter.

The build and package scripts are improved to better automate stand alone package building.

This preemptively adds Kevux specific path global support to easy the package build process for Turtle Kevux. This is done in a non-API and a non-ABI breaking manner.

The IKI standard is found to be slightly lacking. There is a strong need for IKI variables immediately after word-characters that are not part of the variable name. The IKI standard and specification is now updated to utilize open bracket '[' (U+005B) and close bracket ']' (U+005D), commonly referred to as "wrap" or "wrapping". Such an IKI variable looks like [vocabulary]:"content" (as opposed to vocabulary:"content"). New functionality is provided to keep this project compliant with the recent changes to the IKI standard and specifications.

A major behavioral bug has been found in the Controller program regarding the "program" operation mode. Solving this the simple way would then break other behavior. To avoid this, a new feature is implemented, called the "helper" operation mode. The "helper" operation mode provides an alternative to "program" operation mode to allow for starting tasks.

The recent work involving Featureless Make in the 0.7.x development branches has exposed a number of problems whose fixes have been back ported.

The Controller program has now be successfully tested and run under a SystemD system using "cgroups". A quick and simple SystemD "cgroup" example Controller is now provided.

The following are changes since the 0.6.3 stable release.

Check out the project on the FLL release page.

The project is built like a tool chest. Individuals who are unfamiliar with the project should have an easier time trying out the pre-packaged monolithic sources. These programs, by default, are designed to build against a library built using the monolithic source tree.

The stand alone sources for the several programs can be found pre-packaged at Sourceforge.
