MariaDB moves development to Github

Today marks a milestone in terms of the MariaDB project – going forward, the MariaDB project plans to use Github and git for source code management. The migration happens from Launchpad and the bzr tool.

The 10.1 server development (under heavy development now) will happen on Github. You can check it out here: https://github.com/MariaDB/server. Feel free to watch, star or even fork the code, and send us contributions!

Previous maria-captains should now provide their Github IDs so that they can be accorded similar status. Send the IDs to the maria-developers mailing list.

The project eventually wants to move the 10.0, 5.5, 5.3, …

MySQL soon to store system tables in InnoDB

In the MySQL team, we are changing the system tables currently located in the mysql schema from MyISAM to InnoDB.

Looking at this historically:

  • MyISAM was the default storage engine up until MySQL 5.5.
  • In 5.5 almost 4 years ago, the default storage engine changed to InnoDB, however system tables used for features such as storing privileges and timezones remained as MyISAM.

Unlike MyISAM, InnoDB is an ACID compliant storage engine, with the behaviour that once a transaction commits, modifications are able to survive power-loss or other failures. This is a solid foundation to build applications on, since developers will need to handle fewer failures. To use an example:

  1. Customer places an order
  2. A confirmation email is sent
  3. Power is lost

Without durability, (2) could occur with no record of (1) occurring! …

MariaDB & MySQL Community Event videos & slides now up

If you couldn’t attend the MariaDB & MySQL Community Event in April 2014, held at the Hilton Santa Clara, fret not as there are slides and videos uploaded for you to watch at your leisure. There is likely to be at least one more community event later this year, so watch the space.

Currently on the page, you’ll find most of the talks with slides and the videos are professionally done – with slide overlays. The audio could be better on some, but for an event that was pulled together by Monty in less than 3 weeks, it’s not too shabby. You can learn What’s new in MariaDB 10, a little more about the SPIDER storage engine, more about …

Proposal to deprecate COM_REFRESH packet

In the MySQL team we are proposing to deprecate the COM_REFRESH packet in favor of specific queries to execute FLUSH commands. To provide a bit of context:

  • The MySQL server protocol allows for clients to speak API commands via both a query and binary protocol interface. The set of the API commands can be seen in the MySQL Client/Server Protocol internals documentation, or very simply as they appear in a single switch statement:
    # ./sql/sql_parse.cc:1009 (simplified view)
    
      switch (command) {
    
      case COM_REGISTER_SLAVE:
      {
        /* do stuff */
        break;
      }
      case COM_QUERY:
      {
        /* parse query, do stuff */
        break;
      }
      case COM_REFRESH:
      {
       /* equivalent to running a FLUSH command */
        break;
      }
      case COM_SHUTDOWN:
      {
        kill_mysql();
        break;
      }
    }

Proposal to deprecate the old password format

Improving security has been a high priority for MySQL 5.7. To give you an idea of some of the changes to date, I recommend reading Todd Farmer's blog: Redefining --ssl option, Password expiration policy, AES256 encryption.

In MySQL 5.7, we are also proposing to remove the 'old' format for saving passwords. To provide some historical context:

  • The old password format is a 16-byte hash and considered to be cryptographically weak. Code appears online (I won't link to it) which allows the hash to be brute-forced in …

Calling for all mysql_install_db feature requests

mysql_install_db is the program that is responsible for bootstrapping a fresh copy of MySQL and making sure all of the system tables are setup correctly. This program is usually invoked by other programs as part of installation, but in the case of .tar.gz downloads will need to be executed manually.

As part of our ongoing efforts to refactor and improve MySQL, we are looking at converting mysql_install_db from its current Perl script to a program written in C++. The aim of this change is to reduce external dependencies (Perl + a set of modules) and improve our cross-platform experience.

We plan for this transition to be mostly function neutral, but are open to feature requests for additional improvements as well.

Have you worked in packaging MySQL?
Do you have any suggestions on how mysql_install_db can be improved?
Please leave a comment, or get in …
