MYSQL Sandbox 3.0.55 and new Github replication scripts


Both MySQL and MariaDB have been busy, each introducing new features, sometimes creating the same feature, often with different syntax.

This is sometimes good for users, who have a wide choice. And sometimes it is bad, as once you are used to the deployment and syntax of one flavor, it is hard to switch to a different one. This problem is enhanced if you are dealing with an application, MySQL Sandbox, that needs to work well with all flavors.

The latest releases of MySQL Sandbox (3.0.51 to 3.0.55) have been necessary to solve minor and major troublesome points with MySQL 5.7.8 and MariaDB 10.1.

The current version (3.0.55) can install all the newest releases, including replication with MySQL 5.7.8 which suffers from a compatibility bug (better explored in a separate article). …

MySQL 5.7.6 is out. Be prepared for big changes



Today Oracle released MySQL 5.7.6 milestone 16. With this, MySQL 5.7 has been in development for over 2 years.
Compared to MySQL 5.6, the changes are quite extensive. The main effort of the team has been focused on speed, with performance reportedly improved from 2 to 3 times compared to previous releases.
A full list of what is new would take too much space here, but I would like to mention some key points:


  • Oracle has spent a considerable amount of energy in the improvement of MySQL security and safety. You will see many new features, but even more old features that were deprecated and more that were removed after deprecation in 5.6.
  • The installation process has been changing in every …

MariaDB 10 is a Sandbox killjoy?

Using MySQL Sandbox I can install multiple instances of MySQL. It is not uncommon for me to run 5 or 6 instances at once, and in some occasions, I get to have even 10 of them. It is usually not a problem. But today I had an issue while testing MariaDB, for which I needed 5 instances, and I the installation failed after the 4th one. To make sure that the host could run that many servers, I tried installing 10 instances of MySQL 5.6 and 5.7. All at once, for a grand total of 20 instances:

$ make_multiple_sandbox --how_many_nodes=10 5.6.14
installing node 1
installing node 2
installing node 3
installing node 4
installing node 5
installing node 6
installing node 7
installing node 8
installing node 9
installing node 10
group directory installed in $HOME/sandboxes/multi_msb_5_6_14
$ make_multiple_sandbox --how_many_nodes=10 5.7.4 …

Speaking at the MySQL NoSQL & Cloud Conference & Expo in Buenos Aires

I am on my way to Argentina, where I will be speaking at the MySQL NoSQL & Cloud Conference & Expo.

I have two talks: one on my pet project MySQL Sandbox and one on replication between MySQL and MongoDB (using another project dear to me, Tungsten Replicator.

It’s my first visit to Argentina and I will try to look around a bit before the conference. And I look forward to see many ex colleagues and well known speakers at the conference. The lineup includes speakers from Percona, EffectiveMySQL, PalominoDB, MariaDB, SkySQL, Tokutek, and OpenStack.

I am looking forward to this trip. My presentation on MongoDB replication is a first for me, and I am always pleased when I can break new ground. I have the feeling that the networking is …

RFC - DBdeployer : Bringing MySQL Sandbox to a new level


MySQL Sandbox is growing old

The MySQL Sandbox project has been around for 8 years, and it has gained considerable attention from the community. I have seen it mentioned in books and articles, used in other projects, and widely adopted by testers and bug reporters.
I have used it for more than testing, and it has saved me many hours of labor by allowing me to create database servers in a few seconds.
Yet, I have gathered a long list of grievance about it, both from my own experience and from other users feedback. Here goes.

  • MySQL Sandbox is not easy to install. For people used to install Perl modules, it feels natural. For experienced Perl users, installing it in user space without root access is …

MySQL Sandbox supports latest MySQL releases, has more metadata and docs

MySQL Sandbox has been updated again. The latest version is 3.0.38, which was just released. There were four releases in the space of one week, and this last one is just a polished edition.

Cherry-picking from the Change log:

  • Added option --bind_address to complement the effects of --remote_access;
  • The script 'enable_gtid' (for MySQL 5.6 +) now is durable. Previously the changes did not survive a restart.
  • Now you can install MariaDB with its bizarre version '10.0'
  • It also works well with MySQL 5.7. A bug prevented the creation of 'enable_gtid', but it …

Provisioning an Oracle slave using Tungsten and MySQL Sandbox

A few years ago, I used MySQL Sandbox to filter binary logs. While that one was a theoretical case, recently I came across a very practical case where we needed to provision an Oracle database, which is the designated slave of a MySQL master.

In this particular case, we needed to provision the Oracle slave with some auditing features in place. Therefore, mass load functions were not considered. What we needed was the contents of the MySQL database as binary rows i.e. the same format used for row-based replication.

To achieve the purpose as quickly and as painlessly as we could, I thought to employ the services of a MySQL Sandbox. The flow of information would be like this:

  1. Install a sandbox, using the same version and character set of the master;

MySQL Sandbox as a riddle

Shlomi Noach is the next chairman of the Percona Live 2013. As such, he has opened the preview of the conference by posting some talks of interests, which includes a riddle to win a free pass.

The riddle went unanswered, and Shlomi submitted it also to members of the review committee, getting only blank stares, including mine.

Who will open your present,
Make you play pleasant,
Tidy your mess,
Do the same for all else?

Wanting to give away the pass at all costs, Shlomi then published a new post, …

MySQL Sandbox 3.0.30 - now adapted to work with 5.5.30 and 5.6.10

The latest releases of MySQL Sandbox, in addition to deal with minor bugs, have mostly been necessary because of compatibility issues in MySQL, both 5.5 and 5.6.

When I found that MySQL 5.6 has some InnoDB tables inside the 'mysql' schema, I had to change the way that the sandbox used to remove all contents (the ./clear command.)

To achieve a smooth clean up, MySQL Sandbox now performs a dump of the mysql schema, and uses that saved data to restore the schema after a complete wipeout.

Unfortunately, when 5.5.30 was released, this operation resulted in a warning, due to a behavioral change.

After a careful change, and about 1200 unit tests, the latest version of …

Easily testing MySQL 5.6 GTID in a sandbox

MySQL 5.6 seems to be ready for GA. I have no inside information about it, but from some clues collected in various places I feel that the release should not be far away. Thus, it's time for some serious testing, and for that purpose I have worked at updating MySQL Sandbox with some urgent features.

I have just released MySQL Sandbox 3.0.28, with more support for MySQL 5.6. Notably in this release, there is suppression of MySQL 5.6 annoying verbosity, additional suppression of more annoying warnings ( actually a bug) when using empty passwords on …
