The client library — libmysqlclient — is part of the same source code repository as the server. It comes both as a dynamic link library (.so), also called a shared library, and as a static link library (.a). During the 5.7 development cycle, we’ve made several improvements to the library, which has resulted in a bump from ABI version 18 to version 20.…

The 5.7.5 DMR is now available, and we’ve made some changes to our build system in this one, so I wanted to spend some time discussing how you would now build MySQL.
When we released our April labs release, I wrote about building MySQL with Boost. Now that the first GIS work using Boost.Geometry has passed all the hurdles and landed in a development milestone release (DMR), it’s time to revisit the topic. From now on (5.7.5 and newer), MySQL needs Boost headers to compile. It’s not optional.
We got a few bug …[Read more]
Section 6: "Profile a real case" 6.1 INTRODUCTION
Profiling & Debugging is an argument that would require an entire book, the aim of this(and the others) posts of this series is to give you the basic knowledge on how to work with these tools and techniques withing Eclipse. For instance if you want to learn to profile with OProfile you should study on the abundant and separate resources, you may start from: http://OProfile.sourceforge.net
6.2 ABOUT NAMING THE PROJECT
Section 5: "Prepare Eclipse for profiling" 5.1 INTRODUCTION
In this part we will prepare Eclipse to profile our recently
compiled(see Part 3) MariaDB(or MySQL).
Profiling means basically measuring where the time is spent by the application.
You may be interested in knowing how much time is spent in a specific function execution,
or you may want to know statistics about the dustribution of function calls, that is operating a data aggregation.
To run MariaDB from Eclipse we will actually create and install the tar.gz package resulting from compilation(See Part 2) in a separate directory, this will allow us to have MariaDB cleanly installed on a separate location and so it will be also easily possible to run it independently from Eclipse.
In these Blog posts series we assume:
yoda as developer user
Section 2: "COMPILE MARIADB IN ECLIPSE"
2.1 Download and prepare sources folder/>
We will need a directory to use as our playground, if you create
yoda in Section 1:
$ su - yoda
$ mkdir -p ~/playground
Download latest MariaDB 10 sources tar.gz and copy the archive into the above directory, you can latest sources from:
This guide will help you in compiling and debugging MariaDB (MySQL, Percona) within the Eclipse IDE on Linux and using cmake for source project preparation. It will be split in parts to keep each post lightweight and with a finite objective. At the end of reading this series of blog posts you should be able to:
- Prepare for compilation any MariaDB (MySQL, Percona) source release based on cmake framework.
In the newly released MySQL 5.7 labs release, users will find refactored GIS functions, as well as R-tree indexes in InnoDB. One notable change is that we have replaced a lot of the native code for geometry computation with an external library, namely Boost.Geometry. In fact, 5.7 will be the first MySQL release that depends on Boost. So why did we make such a move?
In recent years, we have seen a tremendous growth in location based services, and consequently GIS has become a strategically important area for MySQL. Our existing customers require more GIS features, and we believe this is a growing market opportunity.
Up to MySQL 5.6, GIS support in MySQL has been very limited, and the geometry algorithms implemented in MySQL were overly simple and couldn’t handle many corner cases. …[Read more]
We have a new April labs release that you can download from labs.mysql.com. There are more labs releases. Please try them all, but for now let’s focus on the one called “MySQL GIS, InnoDB R-tree, Parser Refactoring”.
The release contains InnoDB R-trees, the first step of our new GIS implementation, a refactored and faster parser and improved condition filtering cost calculations. You can download and run the binaries just like before, but if you want to build it from source, there are some details you should know. Otherwise you may fail to build MySQL (bug #72172).
This labs release requires Boost to build. Specifically, it requires Boost 1.55. But don’t go running off to boost.org looking for the latest tarball just yet — there’s no need for that. The MySQL build system will do everything …[Read more]
