Introducing percona-patches for 5.1

Our patches for 5.0 have attracted significant interest.  You can read about SecondLife's experience here, as well as what Flickr had to say on their blog.  The main improvements come in both performance gains and improvements to diagnostics (such as the improvements to the slow log output, and INDEX_STATISTICS).

Despite having many requests to port these patches to 5.1, we simply haven't had the bandwidth as our main focus has been on developing XtraDB and XtraBackup.  Thankfully a customer (who prefers to stay unnamed) as stood up and sponsored the work to move the patches to 5.1.

To refresh, the most interesting patches are:

  • Performance patches for InnoDB ®. Although …

Fosdem 2010

Fosdem 2010 was my 10th fosdem Edition (including the first OSDEM)
As every year Fosdem suffered even more from it's own success.

On Friday evening ther was the obligatory Beer event... however as people need to eat to .. the Devops crowd fled the scene

I had made reservations for a 20 something group and with the CentOS crowd joining us (as there was some overlap anyhow) we were 25 when we arrived in the restaurant .

Dinner and Discussions were great .. I learned about some new projects and we had some insightfull dicussions on how fat your thin foil should be ...

After dinner we went back to the Beer Event were lots of Free Beer was tasted ...

Saturday was the first full day of Fosdem, as usual Fosdem was the victim of it's own success , too much interresting stuff to see .. too little time.

Lots of Devrooms had the "FULL" sign put up more than you want as a visitor ...
I …

MySQL Ruby Gem CentOS RHEL 5 Installation Error Troubleshooting

# gem install mysql
/usr/bin/ruby extconf.rb
checking for mysql_ssl_set()... no
checking for rb_str_set_len()... no
checking for rb_thread_start_timer()... no
checking for mysql.h... no
checking for mysql/mysql.h... no
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Searching the web for info on this error yields two basic solutions:

  1. Install the mysql-devel package (this provides the mysql.h file in /usr/include/mysql/).
  2. Run gem install mysql -- …
