Using gdb to understand what locks (and when) are really set by InnoDB. Part II.
In the previous post we checked lock requests while executing INSERT INTO t ... SELECT FROM tt where there is an auto_increment column for which the value is generated in the destination table with default innodb_autoinc_lock_mode=1 . Based on it I've repor...

Fun with Bugs #34 - Who has fun to verify your bugs (based on 5.6.21)
This time I decided not just to review all community bugs fixed in recent MySQL 5,6 GA release, 5.6.21, but also to mention who reported them ( Morgan does this recently) and, most important for this post - who verified them. As I've explained long time ago...

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,...

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

Fun with Bugs #35 - Bugs fixed in MySQL 5.6.24

Using gdb to understand what locks (and when) are really set by InnoDB. Part I.
There is a story behind this post. To make it short, the detailed study presented here started when I noted old Bug #72748 in "No feedback" status few days ago. I considered this status totally wrong and started a discussion on Facebook about it (yes, this ...

Fun with Bugs #31 - what's new in MySQL 5.6.17
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 ...
