Who is working on MariaDB 10.0?
+0 Vote Up -0Vote Down

There was some suggestion after my previous post (Who works on MariaDB and MySQL?) that I look at MariaDB 10.0 – so I have. My working was very simple, in a current MariaDB 10.0 BZR tree (somewhat beyond 10.0.3), I ran the following command:

bzr log -n0 -rtag:mariadb-10.0.0..|egrep '(author|committer): '| \
  sed -e 's/^\s*//; s/committer: //; s/author: //'| \
  sort -u|grep -iv oracle

Hacking the Jenkins BZR plugin
+2 Vote Up -0Vote Down

For Drizzle and for all of the projects we work on at Percona we use the Bazaar revision control system (largely because it’s what we were using at MySQL and it’s what MySQL still uses). We also use Jenkins.

We have a lot of jobs in our Jenkins. A lot. We build upstream MySQL 5.1, 5.5 and 5.6, Percona Server 5.1, Percona Server 5.5, XtraBackup 1.6, 2.0 and 2.1. For each of these we also have the normal trunk builds as well as …

Bzr and launchpad tricks: firefox plugin
+3 Vote Up -0Vote Down

If you work with bazaar, you have seen its URIs. You can find the complete list is in the bzr help urlspec. Although I commonly use only a subset of that, like bzr+ssh://bazaar.launchpad.net/~maria-captains/maria/5.2-serg/ and http://bazaar.launchpad.net/%2Bbranch/mysql-server/5.5/.

In addition I often use Launchpad aliases, such as lp:~maria-captains/maria/5.3-serg/, lp:maria/5.3, and lp:869001.

And finally, there are common abbreviations that we have used in MySQL, and …

xtrabackup bazaar repositories upgraded to 2a format
+2 Vote Up -0Vote Down

I have just upgraded the xtrabackup bazaar code repositories to the 2a format. This means that bzr 1.16 is required to access the source code repositories now.

If you get an error like the one below when working with a local branch, you’ll need to run “bzr upgrade” in it (see below for example). For branches on launchpad, you can use the web UI and hit the “upgrade branch” button.

stewart@willster:~/src/percona-xtrabackup$ bzr pull
Using saved parent location: bzr+ssh://bazaar.launchpad.net/%2Bbranch/percona-xtrabackup/

Persistent index statistics for InnoDB
+5 Vote Up -0Vote Down

In browsing the BZR tree for lp:mysql-server, I noticed some rather exciting code had been merged into the Innobase code.

You may be aware that InnoDB will do some index dives when opening a table to get some statistics about the indexes that can help the optimiser make good query plans.

The problem being that this is many disk seeks. It means that on server restart, you have to spend a whole bunch of time seeking around the disk reading index pages.

Not any more.

There is now code merged in to store the calculated …

InnoDB Revision History
+1 Vote Up -0Vote Down

This is a brief overview of the history of InnoDB with respect to the Version Control Systems (VCS) that were used for developing. It could be useful to people who want to trace back in time to find the origins of bugs or features.

Early days
InnoDB was born in the mid 1990s when Heikki Tuuri started developing this masterpiece. Heikki was a lone developer at that time and he did not use any VCS. There is no InnoDB revision history before 2001.

2001 – 2005
Then in 2001 InnoDB was imported into MySQL’s BitKeeper repository and development continued, recording the history there.

2005 …

The venue they chose this year was the "Cordoaria", a former rope factory located in the Belém district, close to the …

Bazaar importmbox plugin
+1 Vote Up -0Vote Down

Releasing and announcing software is win! I’ve had this bumming around for a bit, and for me (and I think others hacking on MySQL) it’s been rather useful. Simple plugin that takes each email in an mbox, applies the patch and commits it with the correct author to a bzr repo. Very useful if you use quilt and bzr together (“quilt mail –mbox” and then “bzr importmbox”).

I finally published it up at:

http://launchpad.net/bzr-importmbox

enjoy.

Aspects and benefits of distributed version control systems (DVCS)
+2 Vote Up -0Vote Down

This blog post is a by-product of my preparation work for an upcoming talk titled "Why you should be using a distributed version control system (DVCS) for your project" at SAPO Codebits in Lisbon (December 3-5, 2009). Publishing these thoughts prior to the conference serves two purposes: getting some peer review on my findings and acting as a teaser for the actual talk. So please let me know — did I cover the relevant aspects or did I miss anything? What's your take on DVCS vs. the …
