Over the last year we have changed the way we test our software from a manual process to a highly automated process. This new system is capable of taking a change from our source code repository and follow it all the way up to where we update our internal staging servers, thus giving us incredibly …
If you are a programmer, you probably know and maybe even love the sprintf family of functions, which format output based on a format specification and on some input data. Here’s a description of the formats available in the GNU libc implementation. I wrote an implementation called format() …
Last week, we revamped the way CFEngine formats output. You can continue to use the old output format by specifying the option –legacy-output (-l), but this is considered deprecated and may be removed in a future version. The key features of the new output format are as follows. Consistent …
Over the past month we have removed a bit of functionality for CFEngine. These were features that were useful (cf-report) and good ideas (knowledge management), but the implementation was either in an unfinished state or the design had unclear semantics (outputs promise type). In order to get a …
Authored by Brian Bennett of Digital Elf I’ve been working a lot with CFEngine newbies. CFEngine has been described as flour, eggs, milk and butter. All the ingredients needed to make a cake. Getting the new CFEngine user to recognize, then become excited about the possibilities that CFEngine …

Hi everyone, Recently we have been thinking about how to make initial steps with setting up CFEngine easier. One way of making CFEngine easier to set up is to remove the need to manually specify the IP address of the policy hub for bootstrapping a client. We decided to use Zeroconf service discovery …
Hello everybody! For those of you following our development, you might have noticed that after our code split there is a new friend in town: libutils. The aim of libutils is to be a toolbox of commonly used data structures, algorithms and other handy stuff. Historically we had several …
Over the past week in CFEngine core dev, some results of refactoring work have come to fruition. We want to make cf-promises a flexible tool for analyzing policy code. Previously, cf-promises required a runnable policy, i.e. a policy that includes a body common control. This made it impractical to …
