Fun with Bugs #42 - Bugs Fixed in MySQL 5.7.12
+0 Vote Up -0Vote Down

MySQL 5.7.12 was released more than 2 weeks ago. New features introduced there in a form of "rapid plugins" are widely discussed, but I am more interested in bugs reported by MySQL Community users that are fixed there. Unfortunately I do not see MySQL Community Release Notes by Morgan (like this) for quite a some time, so I have to continue describing key bug fixes and name people who reported and verified bugs in my "Fun with Bugs" series.

Re: JSON document fast lookup with MySQL 5.7
+1 Vote Up -0Vote Down

This is a response to the JSON document fast lookup with MySQL 5.7 article by Frederic Descamp.

It is very easy to also use MySQL Workbench and the new GeoJSON support to actually show the features.

My query:
SELECT ST_GeomFromGeoJSON(feature->"$.geometry",2) AS feature 
FROM test_features WHERE street='BEACH' ;

The result:

Exploring Metadata Locks with gdb - Studying Simple Case on Percona Server 5.7
+0 Vote Up -0Vote Down

I had forgotten the topic of studying metadata locks with gdb for quite a some time. Now that I've upgraded to Percona Server 5.7 and enjoy the remaining of my last free day as an independent MySQL Support Engineer doing nothing but some blogging, I think it's time to get back to gdb interactive sessions and try to answer the question I've got from customer back in Percona but had no chance to …

MySQL Sandboxes in Docker
+2 Vote Up -0Vote Down

Overview

When I got interested in Docker, I started playing idly with the idea of integrating containers and MySQL Sandbox. My first experiments were not encouraging. Using a container the same way I would use a regular server produced horrible results. I started by creating a Debian or CentOS container, installing MySQL Sandbox, and then importing an expanded tarball into the container. What happens is that tarballs of recent MySQL versions expand to roughly 2 GB of binaries. When you try to put that into a container you get a bloated file system. If you want to expand more than one tarball, you …

Fun with Bugs #41 - Bugs Fixed in MySQL 5.7.11
+0 Vote Up -0Vote Down

I've just noted that Oracle had released new versions of MySQL on February 5, 2016 formally, so while these days I am mostly thinking about the ways to do support properly, remembering my colleagues and trying to understand some of RocksDB internals, it's time to postpone all these and write about bugs again. This time about some of the public bug reports from MySQL Community and Oracle engineers that were fixed by Oracle in MySQL 5.7.11.

As usual, I'll try to mention who had reported a bug and who verified it, as I think that names …

A safer MySQL box in Docker
+0 Vote Up -0Vote Down

The MySQL team has been maintaining a MySQL image on Docker. They have been listening to requests from the community and reacting quickly. So far, they have fixed two bugs that I reported and introduced a feature request that I suggested to make the server more secure.

Thanks, folks!

My latest request was about password management in a MySQL container. I have mentioned in previous posts the compatibility problems introduced by MySQL 5.7 security enhancements. Let me recap the main issues here:

Why log_slave_updates is a bad default
+0 Vote Up -0Vote Down

In a recent post the MySQL product managers asked the community for feedback about proposed new defaults. One of the proposals is to make log-slave-updates on by default.

There are other important options that require some debate. They all look reasonable to me. This one, instead, which …

Frictionless MySQL installation
+0 Vote Up -0Vote Down

I saw an interesting post about the ability of installing MySQL 5.7 without changing existing tools and procedures. The post is a plea to make MySQL installation frictionless.

That post was followed by a conversation on Twitter, where the recent security enhancements are blamed for getting in the way of existing practices and need a rewrite of installation tools.

I know the problem very well, as I have faced the installation change in MySQL …

A Couple of MySQL 5.7 gotchas to be aware of
+2 Vote Up -0Vote Down

MySQL 5.7 GA was released a couple of months ago now with 5.7.9 and 5.7.10 has been published a few days ago.  So far initial testing of these versions looks pretty good and both versions have proved to be stable.

I have, however, been bitten by a couple of gotchas which if you are not aware of them may be a bit of a surprise. This post is to bring them to …
