Well you can almost get there (completely if you're not changing schemas): mysqldump --single-transaction This option sends a START TRANSACTION SQL statement to the server before dumping data. It is useful only with transactional tables such as InnoDB, because then it dumps the consistent state of the database at the time when BEGIN was issued without blocking any applications.

Unfortunately, mysql still doesn't have transactional DDL, I believe...

Nor does Oracle, for what it's worth.

You have got to admire the evil villany we're up against. Buying the 'M' in LAMP and then exploiting that position. Business first, not the heart and minds of developers. Luckily the 'L' + 'A' + 'P' cannot be bought. LAPP stack anyone?

I take it the extra P is for PostgreSQL? As far as I could ever tell, the only advantage MySQL ever had over PostgreSQL 10 years ago is that it ran on Windows, and Postgres did not, back then. Oh, and by skipping ACID features, MySQL was faster. So, back in the day, that drove me to conclude that all the MySQL fans were crazy, and I decided to use Postgres at home, since Windows != server, and having done quite enoug…

Most Rubyists (I have no numbers for this, just a general sense of the community, I could be totally wrong, all generalizations are false, etc) use Nginx nowadays, so it'd be more like LNPR.

You publish a benchmark that says how inefficient this makes MySQL, and then that "feature" goes away.

I was more concerned about the copyright repercussions on clean-room reverse engineering the protocol. Obviously the protocol includes copyrightable information, now.

To the best of my knowledge, the best answer is "nobody knows". There are some vaguely similar things in the precedents, especially when it comes to protocols that require you to use a particular patent to talk to a given device, and IIRC there is some verbiage in some places that distinguishes copying around for simple transmission reasons rather than delivery to an end user (though I can't imagine how to stretch that to cover this case), but in this particular case, nobody knows.

In fact if you spend much time thinking about this it isn't at all hard to come up with a lot of scenarios that law doesn't have an answer for, in theory or in practice.

A nice fiction. The reality is that copyright covers verbatim copying. If you read a book and write a review, the term "derived work" makes English sense, but not legal sense. Similarly, if you read the MySQL code looking for magic words to say to the server to get it to give you data, saying those words is not copyright infringement. It's "learning", not "copying". If anyone used MySQL, I would write a BSD-licensed…

What would happen, if the protocol would require sending a picture of a picture of Mickey Mouse with each request (or some copy-righted novel)?

That's been tested in court before, in Sega v. Accolade (http://en.wikipedia.org/wiki/Sega_v._Accolade). (You had to display a Sega logo before your game could run, so you had to have their logo in your code)

In short, it's fair use.

MySQL is dual-licensed. If you download the community server, it's GPL licensed. If you want to distribute MySQL as part of your application, then your application may have to be GPL licensed as well, which is often undesirable. ISVs and others that need to distribute MySQL can buy one of the commercial editions to get it under a non-GPL license. If you're worried about the future, Oracle agreed to maintain the dual-…

If my PHP connects to a mysql database on the same host, and I sell that host as a product, I need to release that php code?

If the PHP code is hosted on your server, you're not redistributing it, so the GPL doesn't affect you at all.

If you are redistributing it (you ship it to your customers and they deploy it on their servers) I would find a lawyer.

My understanding from the Wikipedia article you linked is that you just had to have the string SEGA in a specific spot on your ROM, and that the logo was in fact part of the Genesis III BIOS. A four-character string and an image are pretty different, copyright-wise.

Oracle has updated the page and clarified their lowest offering:

Embedded Database6

6 MySQL Classic Edition is not available as an Annual Subscription. ISVs, OEMs and VARs can purchase a license to use as an embedded database.
