Update: I’ve been suffering some ungly and stupid bugs today, so I’ve fixed them and released version 0.2. It also includes a new script wp-update-home.

I’ve just published some scripts that help me manage my personal wordpress installations, and publish some plugins I’m working on.

Warning: these are early versions which I use for small tasks. If you find
a bug or have suggestions, contact me at jbernal@warp.es

After some delay we are proud to present MySQL Proxy 0.6.1.

This is a pure bug-fix release and fixes some assert()oins and the win32 support. It was branched off in December and it took a while to clean up the windows package until it passed the tests.

Download it from:

Changes:

• added new features to run-tests.lua (see README.TESTS)
• fixed error handling for socket functions on win32
• fixed sending fake server-greetings in connect_server()
• fixed assert()ions on write-errors

We are working hard on the next release of MySQL Workbench and are trying to follow our plan of getting a release out every second week. A lot of things have already been addressed, some new things came up. But we are clearly moving into the right direction and our investments in unit tests and UI tests seems to pay off as expected. More details in a post later this week.

It’s been a long time since we’ve started this project and it is time to make a checkpoint. So, I’ve decided to release final 1.0 version and make 1.X branch stable while all serious development with deep architectural changes will be done 2.X branch (trunk at this moment).

Changes from previous release:

• Perl semaphores implementation caused huge memory leaks (mmmd_mod).
• Now we do not send any commands to hard offline hosts with dead TCP/IP stack to prevent mointoring problems for other hosts.
• Removed legacy StartSlave method from agent code which caused problems on some Perl versions
• Added a few fixes to prevent non-exclusive roles from moving. This caused internal status structures to …

MySQL Proxy 0.6.0 has been tagged and should hit the mirrors near you pretty soon.

In the last 3 month of development we added a lot more features to the proxy-core which should bring the proxy closer to your needs. As always the proxy is transparent to your application, no requirement for a special language, no special needs for a platform and all customizable for your needs.

The most powerful feature is Read/Write Splitting which allows you to scale a application which is unaware of replication automaticly cross several slaves without changes to your application. Instance Scale Out we say.

The Proxy also became a 1st class citizen in the MySQL world …

So, we did it! New Best Tech Videos site version has been released today. Of course, it could have some issues, and we are really looking forward for your feedback on our support forums.

Let’s review main improvements we’ve made here:

• First of all, I want to mention our first step to socialization of the BTV - all our users could signup now and get their own lists of favorited, commented and voted videos and much more - they could have their own personal RSS feeds.
• Next cool thing we’ve prepared for you is user-generated content! You can find some great videos on the Net and share them with fellow BTV readers. At this moment our posting system works in pre-moderated mode to keep really high level of videos we post here, but later we want to delegate …

It has gotten a bit quiet around the MySQL Proxy over the last weeks, but I can assure you it was worth it.

Here in my hands I hold MySQL Proxy 0.5.0. Not just some binaries, no everything with sources. As always it is dual licensed under the GPL and commercial MySQL license. We worked hard to get everything ready for the release: the wiki, the forums, the public SVN trees ...

The proxy can do magic. Put in your ideas and say the magic words and there ... it works. :)

The proxy is fully scripted now which opens up the proxy to your ideas. The possibilities are endless. I can think of at least of the following features:

• load balancing
• fail over handling
• query analysis
• SQL macros
• query rewriting
• .... much more

The proxy started as side project of me and is now evolved into a full MySQL project maintained by the …

New alpha release 1.0-pre4 of the MySQL Master-Master Replication Manager. This release has lots of major fixes and I’m glad to announce first sponsored port of mmm to non-linux platform - it has been ported to Solaris 10. So, here are our changes in this version:

• Real checks timeouts - I’ve found and fixed lots of problems in checks timeout code and now if you specified in your mmm_mon.conf, that some check should timeout in 5 sec, it would timeout correctly on all supported platforms.
• External third-party tools using - On all supported non-linux platforms mmm will use system binaries for fping and arp_ping so porting to another platforms would be much easier.
• Agent …

• Man pages for mmmd_mon, mmmd_agent and mmm_control scripts
• Startup scripts added/fixed for mmmd_mon and mmmd_agent
• Installation script now requires iproute package to be installed on server.

As always, if you have any questions/suggestions, post them here or in mmm-devel mail list.

So, I’s been a long time since I wrote my last post here. Lots of work and almost no new interesting technologies in my work caused such delay. But today I’m proud to announce release of really interesting project: MySQL Master-Master replication manager - set of flexible scripts for management different MySQL deployment schemes with master-master replication involved.

More information about this software could be found in detailed announce in Peter Zaitsev blog (actually this software was created by me for his company’s client) or at project page. All your questions and suggestions welcomed in …
