A fairy tale

Once upon a time I did an operating system upgrade, a minor one that should do no harm, but just get me up to date by fixing any bugs in the version I had been using. It seemed like a good idea.

All seemed to be fine. I use a package provided by an external vendor and not the one produced by the operating system provider as this vendor provides a newer version of the package and I need that. The vendor has to make his package fit in the os environment his package is built for and normally does a pretty good job.

I use automation to build my systems and when I built a new one some issues appeared. Related to the new version of the OS the provider had enhanced one of his packages and the installation pulled in new dependencies. The install of the external package I use then broke as it conflicted with the new dependency

This is a follow-up, troubleshooting article that goes hand-in-hand with my “Building MariaDB 5.1 on Windows Revisited” post, and covers some problems and their solutions that one might encounter when attempting to build MariaDB from source code on Microsoft Windows.

The first error I ran into was this, on my main compile step (i.e., the 2nd cmake command):

C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\Microsoft.Cpp
Common.targets(151,5): error MSB6006: "cmd.exe" exited with code 1.
[C:\mysql\mariadb-5.1.67\bld\scripts\GenFixPrivs.vcxproj]

That in itself doesn’t tell us too much. Searching the full compile output, we find:

Generating ../../scripts/mysql_fix_privilege_tables.sql
The system cannot find the file specified.
C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\Microsoft.Cpp
Common.targets(151,5):

I previously wrote an article on Building MariaDB 5.1 on Windows, but it was about 1.5 years ago (for 5.1.60; this is for 5.1.67), so I wanted to update this a little since I’ve built it entirely from the command-line this time (as well as highlight a couple problems/solutions – which I’ll cover in a subsequent troubleshooting post). This process it quite similar to my steps for building MariaDB 5.5 and MariaDB 10.0, however it’s slightly different since 5.1 requires you run the configure.js script before running cmake. Aside from that though, things are mostly the same.

Here is the full procedure:

Download 5.1.67

I wanted install MySQL 5.7.1 (1st Milestone Release) on Windows 7 and test it out a bit, so I did, and since things didn’t go as smooth as expected, I thought I’d share my experience, in case anyone else runs into the same issues.

I downloaded the .msi (mysql-5.7.1-m11-winx64.msi) from http://dev.mysql.com/downloads/mysql/ (then click the “Developmental Releases” tab) and installed it following the prompts. That seemed to complete fine, which was great. However, that was it – and not in a good way. I mean, the “installer” basically only unpacked the files to a location.

I was expecting the “configuration” tool to run, but it didn’t. It was not installed, and not an option.

I quickly read through the 5.7.1 changelog and found the config tool is not part of the

We have had some success with the introduction of glimpsee last month. Merci !
I would like to thanks all of you who have registered and those who are interested in glimpsee without even really knowing what’s going on.
It is really important for us to feel enthusiasm about our work, because we work hard to provide a tool that could improve your life.

We hope to offer a public beta release of glimpsee before the end of the year and many more surprises before. Meanwhile, we would like to offer you an incomplete FAQ about glimpsee, enjoy :
 

What is glimpsee?

A few years back, along with some folks at MySQL and in the open source community, we helped kick off a campaign against software patents in Europe.  This was a hot topic and surprisingly, it seemed no large companies were willing to step up the fight.  As a relatively young company, MySQL had a lot to lose if someone went on the attack against us using patents.  While we had a very small number of patents in our portfolio (mostly through acquisitions), we help them only for defensive purposes.  

It's been interesting to see some stories come out from NPR's Planet Money and This American Life shows that shed more light on software patents.

More than once I have wished that mysqldump was never created. In many backup scenarios it is better to use other tools such as xtrabackup. However, there is still times when I end up using mysqldump. For one thing it is included with the mysql packages. It's "always there". Secondly, it sometimes is really a good fit for the tasks. And occassionally, with a bit of work, you can make it do neat tricks. 

I'm going to cover a few of the tricks I have used over the years. Hopefully you will find them helpful. In some cases one of these might even save your bacon.

Trick One:

One of the annoying issues with mysqldump is its lack of flexibility. It's very easy to dump all databases (--all-databases option), or one or more databases (--databases). Even dumping a single table isn't too difficult. But what about all the tables that start with "a"? You

Overview

First off, the important news. Tungsten Replicator 2.1.0 was released today.
You can download it and give it a try right now.

Second, I would say that I am quite surprised at how much we have done in this release. The previous release (2.0.7) was in February, which is just a few months ago, and yet it looks like ages when I see the list of improvements, new features and bug fixes in the Release Notes. I did not realized it until I ran my last batch of checks to test the upgrade from the previous release, which I hadn’t run for quite a long
