A Configuration-Driven Test Automation Tool for Linux: PyMergen

Having dealt with system designs and issues throughout my career, I always felt the need to quickly create and perform benchmark tests on Linux systems. I have finally released a Python tool to accomplish that task.

PyMergen is a configuration-driven test automation tool for Linux. It is intended to be a local command executor to automate repetitive and iterative testing actions on a Linux host to perform benchmarking and metric collection. The default collection logic is built around Linux Control Groups (cgroups) and Perf tools, and the functionality is extensible through a plugin mechanism.

Securing Symfony2 REST services with FOSOAuthServerBundle

Overview In my previous article, I wrote about setting up a Symfony2 REST service using FOSRestBundle. However, this REST service was behind a firewall protected by a generic form_login provider. Not really ideal if you wish to open your REST API to other applications. So in this article, I will try to explain how to set up FOSOAuthServerBundle to protect your REST API methods using OAuth2. Before we start getting into the gritty details, it is a good idea to have a look at the official OAuth2 documentation . Let's begin... FOSOAuthServerBundle Installation You have to install v1.1.0 of FOSOAuthServerBundle if you are using Symfony 2.0.x. If not, see the docs . First, add the following entries to your deps file: [FOSOAuthServerBundle] git=git://github.com/FriendsOfSymfony/FOSOAuthServerBundle.git target=bundles/FOS/OAuthServerBundle version=origin/1.1.x [oauth2-php] git=git://github.com/FriendsOfSymfony/oauth2-php.git Run the vendors script to install these...

Unexpected token "name" of value "if" ("end of statement block" expected) in "WebProfilerBundle:Collector:logger.html.twig"

Encountered this WebProfilerBundle error message when I ran the bin/vendors script to update my Symfony2 bundles. Make sure your deps file is up to date; you need to pay special attention to your version values. In this case, update your twig version to v1.2.0 as illustrated below: [twig] git=http://github.com/fabpot/Twig.git version=v1.2.0 Run the vendors script to update your bundle and the error message should disappear. You can get the most up to date deps file from the symfony-standard repository located at: https://github.com/symfony/symfony-standard/blob/master/deps

Symfony2 SecurityBundle and FOSUserBundle integration: How does it work?

Overview A couple of days ago, I realized I needed to add some new functionality to the login process. Specifically, I needed to track all previous login attempts. Not knowing anything about the new Symfony2 SecurityBundle, I had to go through the underlying code to understand what was going on. In the process, I think got a basic idea about how the new SecurityBundle interacts with FOSUserBundle. Configuration I have a basic security configuration as illustrated below. app/config/security.yml security: encoders: Symfony\Component\Security\Core\User\User: plaintext role_hierarchy: ROLE_ADMIN: ROLE_USER ROLE_SUPER_ADMIN: ROLE_ADMIN providers: fos_userbundle: id: fos_user.user_manager firewalls: main: pattern: .* form_login: provider: fos_userbundle check_path: /user/login_check login_path: /user/login lo...
