Feed: Planet MySQL; Author: Frederic Descamps; This post is the fifth post of a series of articles on extending MySQL with the Component Infrastructure, the list above will be updated as new articles are published: We are back to our component and we will see how we can use the dynamic privilege component service to add a new privilege when we install our component. This privilege will be checked later when we will create our functions. Of course, when we uninstall our component, the privilege also needs to be removed. In this article we will only register and “unregister” our ... Read More

Downloading the sources As written in the first part, there are multiple ways to get the sources of MySQL and I use the repository on GitHub. You need then to have git installed: $ git clone https://github.com/mysql/mysql-server.git Then you need to prepare build directory: $ cd ... Read More

Feed: Planet MySQL; Author: Frederic Descamps; Before MySQL 8.0, to add a feature to MySQL, writing a plugin was the only way. Now it’s possible to quickly extend MySQL Server by writing a component. The MySQL Component Infrastructure is designed to overcome some of the architectural issues of the plugin subsystem, namely: plugins can only “talk” to the server and not with other pluginsplugins have access to the server symbols and can call them directly (no encapsulation)there’s no explicit set of dependencies of a plugin, thus it’s hard to initialize them properlyplugins require a running server to operate This article ...
