Consolidating MariaDB project tools
+3 Vote Up -0Vote Down

It is not a secret that we’ve been kicking the tires and playing with JIRA for project management. After using it since the beginning of the year most of us like the feel of it and we’ve decided that it makes sense to start using it more.

However, to my disdain, I've found out that it only partially work: the sphinx_snippets() user defined function is not included within the plugin library. After some quick poking I discovered that it was not added to the build, and when added, would not compile.
