Continuing on from my previous post, MySQL code size over releases.

I wanted to look at the different branches/patch sets of MySQL out there and work out how far from upstream they deviated. I’m just going to compare against whatever upstream version the most easily accessible version is based on (be it 5.0.x, 5.1.x or whatever).

For MariaDB versions, I removed innodb_plugin and replaced it with xtradb for stats purposes as the MariaDB innodb_plugin is essentially the same as upstream and I don’t want to artificially inflate the diff size.

The first three major versions of MariaDB were all based on MySQL 5.1. I used sloccount and only counted C and C++ code.

So, let’s look at some of the MySQL patch sets/branches that are around. Firstly, let’s look at MariaDB:

I was discussing how to avoid surprising users and someone pointed out that what seems intuitive and rational to one person is often complete insanity for others. The mental gap between a developer and a user can often be a chasm far too wide to cross.

As the start of a bit of a delve into the various MySQL branches and patch sets that have been around, let’s start looking at the history of MySQL itself. This is how big MySQL has been over all of the major releases since the beginning (where beginning=3.23). (edit: These numbers were all gathered using sloccount and only counting C++ and C source files.)

Alongside SkySQL, we participate in SkySQL & MariaDB Meetups. These events are free to attend and you’ll get to meet & speak with SkySQL CEO Patrik Sallner and all round MariaDB man (& MySQL creator) Michael “Monty” Widenius.

“MySQL 5.6: Advantages in a Nutshell.” March 6 at 10 a.m. PST with host Peter Zaitsev.

This Wednesday (March 6 at 10 a.m. PST) I’ll be presenting a webinar titled “MySQL 5.6: Advantages in a Nutshell.” In this presentation, I will provide a brief overview of the advantages MySQL 5.6 offers. My focus is a practical one – to identify the conditions in which one or another feature can be successfully used providing significant gain, explicitly or transparently. There has been a lot of pretty cool stuff done in MySQL 5.6 and my goal is to get you excited to learn more and try it out.

Reserve your spot now and join me on Wednesday by …

I was discussing how to avoid surprising users and someone pointed out that what seems intuitive and rational to one person is often complete insanity for others. The mental gap between a developer and a user can often be a chasm far too wide to cross. Of all the bug reports I’ve filed against MySQL, here is my all-time favorite:

select * from t where a >= 1.0order by a;

Does not cause an error. I believe it should, because there should be a whitespace before ORDER BY.

Similar syntax errors such as “select 1e0from dual” were also accepted as valid SQL. Much soul-searching later, the official reply from MySQL’s development team:

The server behaves properly here:
- “1″ alone can not be an identifier, because it’s followed by a “.”
- therefore, the lexer parses “1″ as the beginning of a …
