What are the requirements? Having a server with HTTP access and no hassles with low traffic limits. At this stage you’ll need about 5GB disk space, and you’ll use rsync to sync from the master servers (we’ll provide you with a script to help with that). Thanks!
With the new releases the traffic is up (not surprising) and while our existing mirrors appear to be doing ok so far, it’ll be good to have more available before we run into capacity or speed problems. We also haven’t yet split for geographic location, that too becomes a possibility with more mirrors.
See the OurDelta blog for details of this release. RHEL/CentOS packages also coming.
You can now apt-get your way to MariaDB 5.1, courtesy of OurDelta and in close cooperation with Monty Program Ab. To get started, simple follow the info on the Debian and Ubuntu pages.

For the GRAPH Engine documentation, see http://openquery.com/graph/doc. It’s not another general purpose engine, it’s a computation engine. Different beast altogether, but darn useful!
Since it’s new code, it’s only in the -Sail patchset (bleeding edge).
Some of you may have run the mysql-test-run tool which is the MySQL test suite. But did you know there are actually multiple suites? If you just run the tool, you don’t get everything!
Check out the mysql-test/suites subdirectory. That’s all the stuff you don’t get when just running the tool normally. If you take a peek at the Makefiles, you will find a target test-bt (build team) which shows the extra calls and parameters for the additional suites.
OurDelta has had some interesting cases where a build that’s otherwise ok would fail when users tried the test suite on their installation. We reckon such a test should definitely pass, and thus we had some more homework to do. So now OurDelta builds with as many tests as exist enabled, on all platforms and architectures. Slow yes, but that’s not an argument to not test something, right? Failing tests
[Read more...]We’ve been able to do MySQL 5.1 binary tarballs for a bit now (great working together with Kristian Nielsen of Monty Program), but packages are bit more tricky. Peter has been working on Debian/Ubuntu while I’ve focused on RH/CentOS. The following is from an OurDelta (trial build run) RPM install on CentOS 5 x64:

Peter Lieverdink (also known as cafuego on IRC/identi.ca, engineer on OurDelta builds and for Open Query) has co-authored a book that’s available since Monday. The title is Pro Linux System Administration published by Apress.
These days some people don’t want to bother with system administration, and either hire or outsource. Others want to find out more and do things themselves (home and small office use), and that’s the intended audience for this book.
Last year, Erik Ljungstrom (sensei in the #ourdelta IRC channel on Freenode) created patch for a bug Arjen identified with the handling of (among others) the open-files-limit option; the patch was first included in the OurDelta build of MySQL 5.0.67.
Now, Sun engineer Guilhem Bichot has committed the (modified) patch into the 6.0-maria tree, so it should appear in 6.0 and potentially 5.4. That’s good.
See http://bugs.mysql.com/40368 for details and history.
As I described yesterday, Open Query is doing some tests on SSDs and other devices pretending to be harddisks (SANs, battery-backed RAID controllers, etc). To aid this, I wrote a small tool to test the different kind of I/O operations MySQL would/could do, which is not quite the same as what other general purpose apps would do, and also not what other test tools measure. For instance, it tries Direct I/O as well as fsync() after each write, and also it a range of different I/O block sizes.
In a nutshell, it’s aimed to do what MySQL does, without MySQL! Testing lots of different setups for this particular purpose (even with fantastic tools like MySQL Sandbox) is a complete pest, and changing InnoDB page size requires a recompile. While Percona has tried a larger page size in the past and decided it wasn’t worth it (the default
[Read more...]We had to apply a weird tweak as the default Ubuntu Jaunty packages are named something like 5.1.30really-5.0.xx. Several people have filed bugs on it with Ubuntu on Launchpad.
What I suspect happened (unconfirmed!) is that Canonical was contemplating putting 5.1 into Jaunty, had it in a beta but went back to 5.0 before release. Since downgrading by version number is a manual process in apt-get, the above hack allows a downgrade that looks like an upgrade…
Our original Jaunty build worked fine if you were starting from scratch, however an upgrade from the default MySQL on Jaunty would not work. Peter has built 5.1.30really-5.0.77-d8-ourdelta, which upgrades happily from the default Jaunty install or any other earlier install (such as from Intrepid). If you upgrade from an earlier Ubuntu version, do make sure you fix up your
[Read more...]OurDelta builds of MySQL 5.0.77-d8 for Ubuntu 9.04 (Jaunty) builds are done, thanks to some smart and fast work by Peter. The packages are getting copied to the main site right now, and the mirrors should be up-to date within half a day or so.
…is that truth is stranger than fiction. Reality does not appear any more plausible than plain nonsense.
We were discussing this yesterday on #ourdelta (Freenode IRC) in the context of How MySQL really executes a query by Baron. Antony Curtis noted that if he’d write a truthful post on that topic, people would think it was made-up regardless of the day of the year!
Another proof of the premise: Baron has now put a giant banner above/below his post, explaining that it was a joke. Apparently that’s necessary?
I tend to come up with neat ideas for April Fools throughout the year, neglect to write them down, and come the day I have a blank. But, given the above, there’s another

I did a couple of sessions on OurDelta at the Linux.conf.au database miniconf: an overview of the project, a short delve into the features, and a “hacking the mysql server for dummies” which was found of particular interest. It’s a pity that session didn’t get accepted into the MySQL conference, it even had MySQL-uberguru Antony Curtis as co-speaker.
In the hacking talk in Hobart, I showed people the basic infrastructure of the source tree, then going through one particular patch and which changes it makes inside the server (and why). This is an excellent way to learn, as patches have a neat limited scope yet they do something significant. The good news is that the sessions were recorded, so when the
[Read more...]While hard at work, it’s important to be visible so people don’t wonder if there’s anything happening… the open source development model is extremely good for this, things are just public all the time. Some may find this a source of stress or potential embarassment, but I think it’s great and overall makes for better quality code, products, and a nicer work environment.
To see what’s going on with OurDelta right now, we need to take a peek at https://code.launchpad.net/percona-patches where the Percona developers have been busy putting in lots of changes in both the 5.0.67 tree (mainly little improvements and fixes to existing patches) as well as working on the 5.1 ports of the 5.0 patches. Launchpad lets you subscribe to a particular branch, so you get notified when there’s a new commit, and see the changeset comment. That’s a very handy way
[Read more...]OpenSQL Camp 2008 has come and gone, and hooray again for Baron who came up with the idea and made most of it happen (but let’s not forget Sheeri!) Events such as these are always educational, but the most interesting stuff happens outside of the organised sessions (and this being an un-conf, they weren’t that strictly planned anyway 
For me (Arjen) a major chunk of the exercise was acquiring jetlag there and back with no days to spare either side, but I feel it was well worth it. I spent most of the time listening and talking with people rather than coding. It was a great opportunity to catch up with Monty, the Percona crew (Baron, Peter, Vadim, Tom, and more - there’s so many of them now!), Brian, Stewart, Jay,

If you start with the d6 build, you probably have ourdelta.org in your repo files rather than mirror.ourdelta.org. Since we moved to using download mirrors, you need to update your repo config files. There are redirects in place for download users, but yum/apt-get generally don’t like redirects. For details on what your config should now look like, just take a peek at the information for each distro we currently support:
This week saw the release of OurDelta patchset d7 build of MySQL 5.0.67, basically a cleaned-up update of the earlier (and first) OurDelta d6 build. The number of downloads/fetches within the first few hours surpassed the total number from the previous weeks.
Downloads and yum/apt-get repository fetches now always go via one of our mirrors, as obviously the main server can’t possibly handle all that attention! By default you just get sent to “somewhere on the planet”, although you can tweak your repo setup to only use specific mirrors. If you want to become a mirror for OurDelta, drop us a line and we’ll be happy to add you in; the more the merrier!
Ubuntu 8.10 Intrepid is now also supported. We welcome input on which additional platforms are desirable.
