Developer tip: test MariaDB install/upgrade quickly with Docker

Here is a quick tip for any developer who might want to test if the latest development version of MariaDB installs/upgrades. Traditionally, developers seem to have a bunch of virtual machines lying around which they use to test MariaDB installation and upgrade related things. Snapshotting virtual images, keeping them up-to-date, starting, stopping etc. takes a lot of time and does not feel very convenient.

A much faster option would be to use pristine Docker images for every test. Docker images however normally only run one process and thus do not simulate a complete operating system and lack vital things like systemd interactions. …

Protected branches – ensuring code quality in git

In order to ensure that new (or changed) code does not break anything, there is an extensive test suite that is run to catch regressions during MariaDB Server development. Developers are expected to run the test suite locally and, after pushing the code to the remote repository, also check that the more extensive tests run on Travis CI and in particular Buildbot do not find any regressions either. However, sometimes developers are sloppy, make mistakes, don’t check the test results and in a hurry to just push their code change on the main branches, and then the test suite gives errors for everybody else from that point on. …
