Fun with Bugs #33 - bugs fixed in MySQL 5.6.19
It seems Oracle released MySQL 5.6.19 yesterday. So, it's time to check what community bug reports are fixed there. Let's start with InnoDB. We have the following bugs fixed: Bug #72079 , "Upgrade from 5.6.10 to 5.6.16 crashes and leaves unusable DB". Hones...

Fun with Bugs #32 - some bugs I've reported in March
Comparing to the previous month I was not really productive bug reporter in March 2014 (partially because I spent few days at a nice FLOSS UK conference where I tried to give a session on PERFORMANCE_SCHEMA ). Just 12 reports, of them 5 documentation reques...

MySQL 5.6.17 will probably be announced officially at or immediately before Percona Live MySQL Conference & Expo next week. But official release notes are already available, so why not to check them carefully to find out what to expect from this 8th minor r...

Fun with Bugs #30 - quick review of my reports in February, 2014
I've got only one comment to my previous post about deadlock , and it was more like a hint based on a different use case, not a real explanation. So far there is nobody who wants to get free beer... Maybe this is even good, as I do not go to the conference ...

I just pushed the new CREATE OR REPLACE TABLE syntax into MariaDB 10.0, for the soon to be released 10.0.8-gamma (RC). (Before we had only CREATE OR REPLACE for views) When using the new syntax, the CREATE statement will auto...

Hi, thanks for your response. 5.6.19 doesn't have the patch applied. But, after some test's, the one in the bug did work, i have a chaos on my system after so many tests, i build from a fresh 5.6.17 package plus the package and then it works.

I thought that oracle has the public source code on bzr, aparently not.

Thanks a lot.

What's wrong with MySQL Manual
I think that MySQL Manual is one of the reasons why MySQL became and still remains popular. I find a lot of useful information (at least references to share with customers, if not real insights) there even after 9+ years of working with MySQL every day and ...

Why not setting up and alternative, "wiki"-style, free as in free-speech, and that has room for all MySQL/MariaDB/PS/any 3rd party-related projects? I got bored: http://myopendocs.org

Magic deadlock: what locks are really set by InnoDB?
Megabytes of text had been written already on InnoDB locking and deadlocks. Still, even very simple cases of deadlocks while working with a table having only one row sometimes make people wonder what happened and why. Today I want to check if this topic is ...
