MySQL Server 8.0.18: Thanks for the Contributions

Tweet

In my blog series about external contributions to MySQL 8 we have reached version 8.0.18 which was released Monday 14 October 2019. Again the community has contributed to make MySQL better. Thank you.

The contributions to MySQL 8.0.18 includes several patches from Facebook as well as patches from Gillian Gunson, Przemysław Skibiński (Percona), Daniel Black, and Satya Bodapati (also Percona). The contributions are:

  • MySQL now provides more control over the use of compression to minimize the number of bytes sent over connections to the server. Previously, a given connection was either uncompressed or used the zlib compression algorithm. Now, it is also possible to use the zstd algorithm (zstd 1.3), and to …

MySQL 8.0.16 was released last week and includes many great features including support for CHECK constraints and upgrades without the need of mysql_upgrade.

MySQL Contributions status

This post is an update to the status of various MySQL bugs (some with patches) that I’ve filed over the past couple of years (or that people around me have). I’m not looking at POWER specific ones, as there are these too, but each of these bugs here deal with general correctness of the code base.

Firstly, let’s look at some points I’ve raised:

  • Incorrect locking for global_query_id (bug #72544)
    Raised on May 5th, 2014 on the internals list. As of today, no action (apart from Dimitri verifying the bug back in May 2014). There continues to be locking that perhaps only works by accident around query IDs.Soon, this bug will be two years old.
  • Endian code based on CPU type rather than endian define (bug …

Improving Sakila database

The Sakila sample database was created almost 10 years ago, as a sample set of data for MySQL courses and examples.

The database was developed by MySQL employees, with substantial contributions form the community.

Recently, the database was updated to use some of the features in MySQL 5.7. As a result, we had two sets of samples, one to use with MySQL 5.0+, and one that only loads with MySQL 5.7.

I filed a feature request, offering a patch to use conditional schema and data changes, which was incorporated very quickly into the official release.

The current release, available within the …

New GPL suits and an open source imbalance

A new round of GPL-based BusyBox suits has been filed, targeting big names in electronics and IT. We’ve long covered these series of GPL-based suits and settlements, but this latest round comes at an interesting time for open source software and its licensing.

First, we have the backdrop of the Oracle-Sun-MySQL acquisition, with opponents arguing to the world and the European Commission, which is reviewing the proposed merger before approving it, in part that the GPL is, ironically, granting too much power to its user, in this case Oracle. I’ve been quoted in the press and honestly agree with …

Automating MySQL Librarian tasks



The MySQL Librarian is a collection of community generated content, easy to search and to extend. If you have missed the announcement, you may look at Introducing the MySQL Librarian..
To add a new link, you have several ways. You can just use the Add A Link feature inside the Librarian. If the link to be added comes from Planet MySQL, every post has a link to facilitate the insertion to the Librarian. For everything else, adding a link is a manual task. Until today. …

The New MySQL Server Release Model

When I joined MySQL back in June of 2005, one of the first “MySQL Truths” I learned and repeated often when discussing MySQL with others was “release early, release often.” If you’ve been using MySQL for any length of time, you know what that statement means – it meant that MySQL was: (1) dedicated to getting new features and enhancements into the hands of its community so the software’s quality could be validated; (2) eager to take early feedback on those features so the input could rapidly be incorporated back into the product allowing everyone to benefit; (3) committed to very frequent releases of the software so helpful new features and/or external contributions that were ready for action could quickly be put into play and not sit idle on the shelf. And if you’ve been around Open Source for a while now, you know this is the spirit in which most providers of Open Source software operate.
