Fun with Bugs #11 - Top 10 Optimizer Regression Bugs in MySQL 5.6
+1 Vote Up -0Vote Down

I've got a question from colleague last night on what bugs should users take into account if they plan to upgrade to MySQL 5.6 now. Simple answer is: it depends. If one of the new features or scalability improvements are really important, then bugs in other features or clearly identified problematic use cases may be just ignored or avoided.

But to be on a safe side users should at least check if they are (or may be) affected by a known regression bugs, when new version is slower or produce wrong results or crashes in cases that worked without problems before.

List of bugs in MySQL 5.6 that can be formally …

Fun with Bugs #10 - recently reported bugs affecting MySQL 5.6.12
+0 Vote Up -0Vote Down

MySQL 5.6.12 is available to community for more than a week already, so people started to test and use it. And, no wonder, new bug reports started to appear. Let's concentrate on them in this issue.

I'd like to start with a funny one.  Bug #69413 had scared some of my Facebook readers to death, as we see kernel mutex mentioned clearly in the release notes for 5.6.12. What, kernel mutex comes back again? No, it's just a result of null merge and, probably, …

So, it seems we have MySQL 5.6.12 released officially. We have great Changes in MySQL 5.6.12 page already widely shared and people already blogging about a feature implemented by my dear friend Sinisa.

Quick scroll over changes shows 130+ bugs fixed and it will surely take time to understand the impact of all these fixes. We have 2 months for this till next release, so eventually we'll find out what's good in …

Fun with bugs #7, still mostly about 5.6.11
+1 Vote Up -0Vote Down

It looks like now Oracle will release new 5.6.x every 2 months, so while I'd happily write about bugs fixed in 5.6.12 we still have to wait for the official release to happen. I am too impatient to wait for 5.6.12, so let me write this post of a classical kind - just a summary of my MySQL bugs' related posts on Facebook since the previous one.

I have to start with replication-related bugs in 5.6.11 pointed out by …

MySQL Sandbox supports latest MySQL releases, has more metadata and docs
+2 Vote Up -0Vote Down

MySQL Sandbox has been updated again. The latest version is 3.0.38, which was just released. There were four releases in the space of one week, and this last one is just a polished edition.

Cherry-picking from the Change log:

  • Added option --bind_address to complement the effects of --remote_access;
  • The script 'enable_gtid' (for MySQL 5.6 +) now is durable. Previously the changes did not …

Last time I had written about bugs here it was a beginning of February, and hardly somebody could imagine that we were going to have 2 more months of winter, 2 more months to wait for next MySQL 5.6 GA release or that in 2 months and two weeks I'll be speaking about MySQL in public for 50 minutes based on my own presentation, and speaking about bugs (surely)...

In any case, MySQL 5.6.11 …
