Testing MySQL 5.5 semi-synchronous replication
+12 Vote Up -0Vote Down

A few days ago I saw an article about Semi-Synchronous Replication in MySQL 5.5. It asks questions, and doesn't give answers beyond gut feeling. So I thought that I would do some practical testing of this new feature.
Before we go that way, though, let's revisit the theory.
How semi-synchronous replication works
Figure 1. A transaction with regular replication
With regular replication, you send a transaction to the master (1). When the COMMIT is received, the master executes it (2), and if successful it …

Slapping MySQL-Proxy
+0 Vote Up -0Vote Down

I have old applications that need to read (and write) MyISAM tables that themselves receive lots of bulk updates. Time to try MySQL-Proxy.

MySQL Proxy is light on documentation and very few people written anything about working.   Most of what I have read says MySQL-Proxy is not ready for prim time.  I have hope so I had to give it a try.

I started with thee VMware servers. I setup one master and two read only slaves.   I tested the replication with mysqlslap

Performance gain of MySQL 5.1 InnoDB plugin
+6 Vote Up -0Vote Down
You know already that InnoDB in MySQL 5.5 has great improvements in performance and scalability. You will have to wait a few months for that, though, because MySQL 5.5 is not GA yet.
But if you need some extra performance in MySQL 5.1, you may want to use the Innodb Plugin instead of the built-in one. As of version 5.1.47, the Innodb plugin is of GA quality, and it …

Down the rabbit hole
+0 Vote Up -0Vote Down

Generally I avoid going down rabbit holes but today I decided to see how deep a particular testing rabbit hole went. This post is a third in what seems be a continuing series of programming anecdotes. It’s not particularly MySQL-related so you can stop reading here unless you grok code stuff.

Before beginning work on issue 720 I ran the mk-table-checksum test suite to make sure it was in working order. No sense writing new tests and code when the old tests and code aren’t reliable. I actually …

Reviewed: Python Testing by Daniel Arbuckle
+0 Vote Up -0Vote Down

I’ve recently had the pleasure of reading “Python Testing: An easy and convenient approach to testing your python projects” from Packt Publishing. It’s been a quick read but a solid set of instructions on the different methods for the subject.

The book starts out very quickly with details about the various methods that are available, the means of automation for testing, and of course the environment you’d want to be in for working on the subjects that the book covers. It …

MariaDB Buildbot configuration file published

I have now published the Buildbot configuration file that we use for our continuous integration tests in our Buildbot setup. Every push into main and development branches of MariaDB is built and tested on a range of platforms to catch and fix any problems early (and we also test MySQL releases before merging to easily see whether any new problems already existed in MySQL or were …

Building MariaDB/MySQL with Buildbot and KVM
+5 Vote Up -1Vote Down

Testing and automation. These two are key to ensuring high quality of software releases.

Ever since I worked briefly in the team at MySQL AB that is responsible for creating the binary (and source) packages of MySQL releases, I have had the vision of a fully automated release procedure. Whenever someone pushes a new commit to the release branch revision control tree, the continuous integration test framework should kick in and do all the steps needed for producing release packages:

  • Checkout the new revision.
  • Build a source tarball, and save it. …
