cmocka 1.0


The cmocka project finally released version 1.0. cmocka is a unit testing framework for C with support for mock objects.

In software development, unit testing has become a standard part of many projects. They use tools like cmocka to check some of the functionality of the source code. Unit-testing frameworks allow testing of low level functionality and ensure that all software components are working correctly and often prevent regression if you do code changes.

Another month just went by and it is time to wrap it up with the monthly JBoss news blog post.

Top 3 Reasons to Run Container-Based Applications on Red Hat Enterprise Linux 7 | Red Hat Enterprise Linux Blog


This article was written by Red Hat’s Siddharth Nagar, RHEL 7 product manager.

Shipping_containers_at_Clyde“As product manager for Red Hat Enterprise Linux 7, part of my job is to ensure that the latest version of our flagship product adheres to our promise of stability, reliability, and security.  In addition, as Red Hat Enterprise Linux 7 is Red Hat’s latest enterprise Linux platform, it also needs to incorporate new innovations in technology to help our customers gain business advantage, reduce costs, and increase efficiency without compromising their existing investments. With this in mind, the Red Hat Enterprise Linux team takes great care in evaluating new technology to ensure that it is introduced in a manner that is minimally intrusive (if at all) and is a natural fit for the platform. Support for Linux containers and the ability to host container-based applications are great examples of this and Red Hat Enterprise Linux 7 stands ready for the challenge. (more…)

Inspecting docker activity with socat


Lately I’ve been busy working on an Eclipse plugin that will support a wide range of docker functionality. Some of that has involved looking at some docker client libraries, figuring out how it works in one implementation, and seeing how this can be ported to other implementations. While the Docker Remote API is well documented, it can still be tricky to get things right.

When I’m debugging some failed interaction, I’ve found socat to be very useful.

Let’s say we want to inspect all traffic going through ‘unix:///var/run/docker.sock’ . We can’t directly sniff the traffic on it as we don’t really control this socket. We first create a fake unix socket, say ‘/tmp/fake’ and relay all its traffic to ‘/var/run/docker.sock’ . In this way, regular interactions remain undisturbed, but the redirect allows socat to inspect traffic. (more…)
