Fun with Bugs #29 - important bug fixes in MySQL 5.6.16
+3 Vote Up -0Vote Down

As you should already know, Oracle had released MySQL 5.6.16 officially on January 31, 2014. You can find all the details in official release notes. In this post I decided to concentrate on important fixes for bugs reported by community in 4 most important categories: InnoDB, replication, partitioning and optimizer.

Let's start with Bug #70768, "Persistent optimizer statistics often causes LOCK_open stalls". It's well known that persistent statistics for InnoDB …

Fun with Bugs #26 - MySQL bugs Oracle had not fixed for me (yet)
+0 Vote Up -0Vote Down

In the previous post in this series I've listed 15 MySQL bug reports, documentation and feature requests I've made in 2013 that got fixes or any other kind of solution. Now it's time to check what happened to the rest and try to think why.

First of all, no MySQL bug reporter is perfect (if only …

Fun with Bugs #25 - MySQL bugs Oracle fixed for me this year
+0 Vote Up -0Vote Down

I've checked recently and noted that I've sent 50 reports about MySQL bugs, features I'd like to see and unclear/missing manual pages this year. It all started with famous Bug #68079 (reported on January 14, 2013), that got a lot of attention, valuable workaround from Oracle and caused a lot of work that is going to improve MySQL scalability substantially in the future.

Oracle had also implemented this my (and not only mine!) feature request, Bug #69527, and in MySQL 5.7.3 PERFORMANCE_SCHEMA …

MySQL RPMS and the new yum repository
+1 Vote Up -0Vote Down

I was really pleased to see the announcement by Oracle MySQL yum repositories that they have now produced a yum repository from where the MySQL RPMs they provide can be downloaded. This makes keeping up to date much easier. Many companies setup internal yum repositories with the software they need as then updating servers is much easier and can be done with a simple command. For many people at home that means you set this up once and don’t need to check for updates and do manual downloads, but can do a quick yum update xxxx and you get the latest …

Quick link to Percona Toolkit bugs

In this post I wanted to highlight

percona.com/bugs/<tool>

 , for example: percona.com/bugs/pt-stalk.  This only works for Percona Toolkit.  We often advise people to check a tool’s current bugs, but we don’t always say how.

The official link for Percona Toolkit bugs on Launchpad is  …

Fun with Bugs #24 - PERFORMANCE_SCHEMA
+1 Vote Up -1Vote Down

It seems that one of my session proposals is accepted for Percona Live London 2013, so I have to prepare myself to speak about PERFORMANCE_SCHEMA new features and problems in MySQL 5.6. Bugs are going to be discussed, among other things. Let's check current active bugs (and some "Not a bug"s) related to PERFORMANCE_SCHEMA in this issue.

I'd like to start with Bug #68514 that got some attention this week again, in despite of its "Not a bug" …

It's all about bugs fixed: MySQL 5.6.14
+0 Vote Up -0Vote Down

Most of MySQL gurus and famous users are probably in San Francisco now, getting ready for fun at MySQL Connect. Part of that fun should come from the announcement of great new MySQL 5.6.14 release (that somewhat silently happened yesterday).

I am sitting at home though and I've seen at best 3 sunny days in September. The rest of the time it rains, so hardly I can do anything more funny and useful than review of MySQL bug reports even during my weekend. Let me try to tell you what MySQL 5.6.14 is really about and what you should expect …

New Shard-Query features checked into SVN
+0 Vote Up -0Vote Down

I checked some updates to Shard-Query into SVN. Partitioning support has been extended for MySQL 5.6+ to ALL partitioning types.

This includes all previously unsupported types including RANGE LIST/COLUMNS partitioned tables that are partitioned over more than one column, and HASH/KEY/LINEAR variants as well. Shard-Query now exclusively uses the PARTITION hint for partition elimination instead of WHERE clauses in MySQL 5.6. For 5.5 and previous versions, support remains limited to LIST,RANGE, and LIST/RANGE COLUMNS over a single column.

The old mysql interface DAL has been replaced completely by the PDO DAL.

There is no major …

MySQL Bugs Verification - Is It Really Simple?
+1 Vote Up -0Vote Down

While it was explained already by Sveta and others what does it really mean to "Verify" (or "Confirm", in Launchpad/Percona's terms) a bug in MySQL software, and why this step in a bug's life cycle is important, we still often read complains about too much time taken to verify the bug even with a clearly repeatable test case that can be just …
