Who's afraid of MySQL forks?
There is much talk about MySQL forks and how they are going to replace MySQL, or take over MySQL user base, or become more powerful/profitable/popular/you-name-it than MySQL itself.
Let's clear some air on this topic. There is more about forks than meets the eye, especially if you think about a few obvious facts.
What's a fork? According to Wikipedia
a project fork happens when developers take a legal copy of source code from one software package and start independent development on it, creating a distinct piece of software.

By this definition, when someone who doesn't work at the MySQL project distributes a package that is based on MySQL code but differs …

Oracle Blamed for Laws of Nature

A catchy headline, and I believe more accurate than Oracle Puts the Squeeze on SMBs with MySQL Price Hike (Network World) and MySQL price hikes reveal depth of Oracle’s wallet love [MySQL Jacking up MySQL Prices] (The Register). Slightly more realistic is Oracle kills low-priced MySQL support (again The Register).

First, let’s review what Oracle has actually done: they ditched the MySQL enterprise Basic and Silver offerings. For Oracle, that makes sense. Their intended client base is “enterprise” (high end, think big corporates) and their MySQL sales and cost structure reflects this. It’s not a new thing that came with MySQL at Oracle, because MySQL at Sun …

Long tails on licensing questions

In my time at MySQL AB in the Community Relations possition (2004-2006) I wrote several articles on MySQL’s licensing for the MySQL web site. The core reason for having to explain anything was (and still is) the dual licensing of MySQL, in particular the client library. I left MySQL AB years ago, but people still ask me licensing questions. Below is an excerpt from one such question, and my response.

Protocol, the GPL, and how Bazaar can help

Mark Callaghan asks Can a protocol be GPL?, after finding a disturbing comment in a source file: Any re-implementations of this protocol must also be under GPL, unless one has got an license from MySQL AB stating otherwise.
I recall talking with one of the company lawyers about this matter, and he assured me that the GPL can't be used for a protocol, and that's why this notice was dropped from site a few years ago, even before the Sun acquisition.
This is thus an embarrassing piece of ancient history (which will hopefully be removed soon) that has been in our files for long time. For how long?
If we get the source trees from the public bazaar …

So tired of MySQL's old "GPLed network protocol" FUD.

Over in the blog post High Availability MySQL: Can a Protocol be GPL? Mark Callahan found the following comment in the source file sql/net_serv.c

This file is the net layer API for the MySQL client/server protocol, which is a tightly coupled, proprietary protocol owned by MySQL AB. Any re-implementations of this protocol must also be under GPL, unless one has got an license from MySQL AB stating otherwise.

I am second to few in being a fan and a proponent of the GPL.  However, this claim in this comment is utterly bogus. It dates back to willful misunderstanding and FUD spreading and the desire to strong-arm the sale of licenses on the part some people at the old MySQL AB company.

If license of source code followed network protocol of running implementation (which stretches "derived work" to an extent even …

As the GPL fades

We’re continuing to see signs that the dominant GPL open source license may be fading from favor among commercial open source software players. The latest move away from the GPL comes from content management software vendor Alfresco, which is moving to the LGPL after originally releasing its code under the GPL three years ago. The reasoning for the shift, according to Alfresco CEO John Newton, is the company sees greater opportunity beyond being a software application, particularly given the emergence of the Content Management Interoperability Services standard. Alfresco won mostly praise for its move, and it does make sense given where open source is going these days.

I believe the emerging trend away …

If you really want to "save" MySQL, start by encouraging them to release their docs under the GPL

I've talked about this before, but I think it bears repeating as we enter a new year. Sun has still not released the MySQL documentation under the GPL license, or any other free license. It's still not legal to modify and republish the database documentation. This hurts projects like XtraDB, MariaDB, Kickfire, Infobright and other companies which either have forked the GPL licensed version of MySQL, or entered into a proprietary license agreement with Sun.

These companies can't update the documentation to reflect the changes and enhancements which they have made to MySQL. I can't take the docs and publish changes or annotations without violating the license agreement for the docs.

If Sun wants to claim that MySQL is true open source then they must open source the documentation. If Oracle wants to claim that there is plenty of competition in the database market, they should be forced to open source the documentation. …
