Fun with Bugs #45 - On Some Bugs Fixed in MySQL 5.7.15

Oracle released MySQL 5.7.15 recently, earlier than expected. The reason for this "unexpected" release is not clear to me, but it could happen because of a couple of security related internal bug reports that got fixed:

  • "It was possible to write log files ending with .ini or .cnf that later could be parsed as option files. The general query log and slow query log can no longer be written to a file ending with .ini or .cnf. (Bug #24388753)
  • Privilege escalation was possible by exploiting the way REPAIR TABLE used temporary files. (Bug #24388746)"

Let me concentrate on the most important fixes to bugs and problems reported by Community users. …

Some thoughts on recent events (repost)

[something happened to this post and I am reposting it]
It was suggested by Monty that the posts I've made about MariaDB are for publicity. This simply isn't true. I would have much preferred a different outcome in my interactions with MariaDB. I figured that they would end up giving me a hard time, and I'd be stubborn and we'd both hate each other for as long as I could keep from leaving. A quick separation actually seems much better in such context. Regardless, I would have preferred to speak amicably to the MariaDB Corporation about switching the license back, or at least moving to the new license at the time of the notification of the community, ie, changing the license so that bug fixes for 1.3.4 were not mingled with new 2.0 features.

It could have been easily possible to have a 1.3.5 release that fixes the major bugs in 1.3 and then release a new set of features as 2.0. This would have been at least reasonable, but by …

Creating a MariaDB MaxScale router module

I wanted to do some tests with MariaDB MaxScale and realized that the two existing routers (beyond the binlog router that is, which is a bit special) didn't do what I wanted them to do. What I was looking for was a simple round-robin feature and none of readconnroute nor readwritesplit could be configured to do this, they are just too smart for my simple experiment.

Why would you want a round-robin router then? Well, one use case is when you are INSERTing a lot of data and you just want to persist it. You don't have the use case where you have to SELECT data from all servers, but in the case you need it, you just select from all servers until you find what you need. Let's think about log data that you don't care much about but that  you for some reason need to retain, maybe for corporate policy reasons or legal reasons. Using round-robin could, in theory, give you better performance, but that would require something way smarter …

Regardless, I would have preferred to speak amicably to the MariaDB Corporation about switching the license back, or at least moving to the new license at the time of the notification of the community, ie as the LAST checkin in the 2.0 branch. I would suggest they re-release 2.0 as GPL and move 2.1 to the BSL to allow the market to decide if they want to move to 2.1, or even take up 2.0, if they aren't guaranteed important (especially security!) fixes in the older …

On Open Source and Business Choices

Open Source is a whole-of-process approach to development that can produce high-quality products better tailored to users’ real world needs.  A key reason for this is the early feedback cycle built into that complete process.

Simply publishing something under an Open Source license (while not applying Open Source development processes) does not yield the same quality and other benefits.  So, not all Open Source is the same.

Publishing source of a product “later” (for instance when the monetary benefit has diminished for the company) is meaningless.  In this scenario, there is no “Open Source benefit” to users whatsoever, it’s simply a proprietary product. There is no opportunity for the client to make custom modifications or improvements, or ask a third party to work on such matters – neither is there any third party opportunity to verify and validate either code …

Thoughts on MaxScale new license

MaxScale has been open source until now, just like all MariaDB projects. But the 2.0 version is released under a new license called BSL, which basically makes the covered work non-free until the Change Date (in this case 2019-01-01), when the license will be converted to GPL.

Looks like open source friendly, after all. The license will be GPL, just be patient. And the code is available. Right?

No. Cmpletely wrong. For plenty of reasons.

Some reasons

It is a lock-in. No matter how many times Monty repeats that there is no lock-in, we have a brain. If you don’t allow anyone to fix bugs except for yourself, it is a lock-in. If you force your users to buy your support, they won’t buy your competitors support.

MariaDB business moves to a non-free product. Yes, 1.4 is …

Fired for supporting open source

I have been fired for speaking out about the GPL and MariaDB actions that have caused great harm to our ecosystem.

It has been pointed out that I have a non-compete agreement. None of my tools compete with MariaDB and I have no non-public knowledge of MariaDB technology. GPLScale remains free software under the GNU GPL license and it is my right to fork a github repo. I am not paid to work on GPLScale and I don't intend to get paid to maintain it by anyone. All my projects are labors of love.


Who wants to hire me? I'm dedicated, honest, open, and I have integrity. I'm willing to risk everything for what I believe in.

I have been a proponent of GPL for a long time, and I don't need publicity.

Emulating Sequences in MySQL and MariaDB

Sequences are objects defined by the SQL standard that are used to create monotonically increasing sequences of numeric values. Whenever nextval is called on a sequence object, it generates and returns the next number in the sequence. For MySQL and MariaDB users, this might sound similar to MySQL’s AUTO_INCREMENT columns, but there are some differences: Sequences are defined by the ... Read More

Basically Shitty License

Monty announced that he has created a new non-open source license called the "Business Source License" or BSL.  I think it should have a different name...

You see, Monty has fundamentally crafted a straw man to stand in for the general Open Source model by applying his experience in the dog-eat-dog world of forked software, in particular, the "ecosystem" of MySQL.  The software that MariaDB draws the majority of their income from is MariaDB, which is a fork of MySQL.  If you don't know the history, well, you see, SUN bought MySQL, Oracle bought Sun, and Monty, in an environment of nearly Biblical levels of FUD, forked MySQL into MariaDB (both products are named after his daughters).

While MariaDB was originally envisioned as a "drop in/drop out" replacement, it has diverged so far from the Oracle product that it is no longer even "drop in" with the latest versions of MySQL. Oracle is adding amazing new …
