A while ago I asked for people and/or organizations to sponsor development on Maatkit (formerly MySQL Toolkit) so I could take a week off work and improve the Table Sync tool. I asked for $2500 USD, but several companies have graciously offered to cover that and then some.

I'm very happy about this, as it will allow me to dedicate a solid week to fixing bugs and adding features. There's a lot of demand for the tools, and there are a dozen or so bug reports unresolved for the table-sync tool, which I personally want to fix as much as anyone. So I'm very grateful for the support.

Here are the companies who have promised their financial support:

As a follow up to my post about Cesar Cerrudo's new whitepaper, earlier this month David Litchfield talked about putting honeypots in the database in his blog post, Database tripwires..., to catch someone snooping around. The basic idea for non-Oracle databases is to create some sort of alerting function (such as one that fires an email) that gets called by a view with an interesting sounding name or interesting sounding column names. Triggers could work for INSERT, UPDATE, and DELETE, if the attacker is attempting to alter data. However, if the attacker is simply collecting information, then triggers aren't effective because triggers can't be defined on SELECT operations. This is why he …

Maatkit (formerly MySQL Toolkit) version 1297 contains a significant update to MySQL Table Checksum (which will be renamed soon to avoid trademark violations). The changelog follows. What you don't see in the changelog is the unit test suite! I got a lot more of the code into modules that are tested and re-usable.

2007-11-18: version 1.1.19 

* Check for needed privileges on --replicate table before beginning. 
* Made some error messages more informative. 
* Fixed child process exit status with 8-bit right-shift. 
* Improved checksumming code auto-detects best algorithm and function. 
* Added --ignoreengine option; ignores federated and merge by default. 
* Added --columns and --checksum options. 
* Removed --chunkcol, --chunksize-exact, --index options. 
* --chunksize can be specified as a data size now. 
* Improved chunking algorithm handles more cases and uses fewer chunks. 
* Do not print --replcheck results for servers that are not …

Maatkit (formerly MySQL Toolkit) has for some time been released both as a bundle, and as individual tools. It's too much work to maintain the individual packages, and I don't think it really benefits anyone much, if at all. While the tools will still be versioned separately, I'm going to discontinue releases of the individual packages, and just release the one uber-package from now on.

This will also make it easier for me to manage the name change, but that's just an extra incentive; I've been considering this for a while.

By the way, Sourceforge indicated it would take up to a couple of days to finish the project's rename, but it took only a few minutes. Lots of broken links; I've asked for a permanent redirect from the old URLs to the new.

I am so lucky I married an archaeologist.

Choosing a new name for MySQL Toolkit has been a hassle. I wanted to avoid a literal name, such as, um, MySQL Toolkit. Short is good. And so on, and so on. All the while, the Phoenix/Firebird/Firefox naming debacle was in my thoughts. I only want to do this once.

This release fixes several bugs introduced in the last release as I replaced untested code with tested code -- how ironic! Actually, I knew that was virtually guaranteed to happen. Anyway, all the bugs you've helped me find are now fixed. I also fixed a long-standing bug in MySQL Table Sync, which I am otherwise trying to touch as little as possible for the time being. (Remember to contribute to the bounty, and get your employer to contribute as well, so I can do some real work on it in the next month or so!)

The other big news is that the parallel dump and restore tools are now 1.0.0 because I consider them feature-complete. I have put the most work into tab-separated dumps. These two tools can do something MySQL AB's tools can't currently do: restore data before creating triggers (when doing tab-delimited dumps). That's an obvious …

The 1.5.2 release of innotop contained two bugs, one very minor. The other was a crash because of the new functionality that aggregates results across many connections. I fixed them and released version 1.6.0, which I consider stable and ready for everyone to use. (My version naming convention for innotop is that even-numbered minor versions are for production use; odd-numbered, such as 1.5.2, are the development branch. That's why I release them under the innotop-devel package).

Your comments are welcome for the 1.8 roadmap.

Yep, it's true. "MySQL Toolkit" technically infringes on MySQL's trademark. I haven't been given a mandate or cease-and-desist order or anything, but as Marten Mickos (MySQL's CEO) told me, anything that starts with the word "MySQL" sounds like it comes from the company, and this project doesn't come from MySQL.

Suggestions are welcome. I'm totally uninspired. "Toolkit" was the best I could do when I named the project to begin with.

Thanks to a patch Dane Miller submitted, MySQL Heartbeat can now be used to monitor Slony-I replication lag for PostgreSQL. It works identically: it updates a record on the master and looks for it on the slave. You just have to specify the database driver on the command-line:

mysql-heartbeat [options] --dbidriver=Pg

Most of the tools in the MySQL Toolkit are very MySQL-specific. This one just happened to be an exception, and I'm happy it's useful for more than the original purpose.
