I had first seen the interesting Rails logo in a talk by Terry Chay, while I was at OSCON, a few months ago.
Now, my esteemed colleague Jay Pipes has it on his laptop. It seems they’re making stickers, even.
Otherwise, my next task is to revamp our Ruby content. Currently, it looks a little sad. It has to at least be as good as Using MySQL With Ruby, no?
So, you want to compile Workbench for Linux, on Fedora 9. You need to install the following packages:
autoconf automake libtool libzip-devel libxml2-devel libsigc++20-devel libglade2-devel gtkmm24-devel mesa-libGLU-devel mysql-libs mysql mysql-devel uuid-devel lua-devel glitz-devel glitz-glx-devel pixman-devel pcre-devel libgnome-devel gtk+-devel pango-devel cairo
I feel I’m being too liberal with dependencies, but I’m not about to strip it, I just want to get it working first :)
You need to have ctemplate and ctemplate-devel installed from updates-testing-newkey (relevant koji build log).
By default, configure.in in Workbench looks for “google-ctemplate”, as opposed to just “ctemplate” as Fedora calls it. You can fix this (easy), or “cheat” – in /usr/local/include you can do sudo ln -s /usr/include/ctemplate google. Take your pick.
Now for the fun. Fedora includes gcc-4.3. Ubuntu ships gcc-4.2. Let’s just say gcc-4.3 got stricter (its C++ header dependency streamlining related). So strict, they have a useful porting to gcc-4.3 guide. Just FYI, I believe OpenSUSE is also shipping a more modern GCC (I expect the next Ubuntu release in the coming month to do the same).
So, start getting used to doing the following in files that lead the compiler to fail:
This will help get rid of error messages like: error: 'memset' was not declared in this scope. This stuff is already fixed in trunk (or the patch is being applied).
You will need to pick up cairo from source. Why? Because --enable-glitz isn’t on by default in the RPM spec file (similar with Ubuntu). The glitz backend is apparently still a release preview and doesn’t fully work yet. (I have spoken to Alfredo, and he says he’s just removed the requirement on glitz in trunk).
Now, once you’ve built cairo with glitz, before running ./autogen.sh, do: export PKGCONFIG_PATH=/usr/local/lib/pkgconfig. Then go ahead and make it.
There are still plenty of warnings that spew by. I have this vague idea that once Workbench for Linux sits on Launchpad, we’ll run a janitorial tree that fixes warnings in the code. A great way to garner community contributions!
Anyway, a lot of this is either fixed or patches will be applied to trunk. I expect a mysql-workbench-5.1.2-alpha out sooner than you think to eclipse 5.1.1-alpha. Again, superb work Alfredo (and MikeZ and the rest of the GUI team).
Excited with the release of the MySQL Connector/C++, I thought I’d get it going on Mac OS X.
You’ll first hit the problem that Mac OS X doesn’t come with CMake. So you’ll have to download it from the site – there’s a warning there that the .dmg installer only works for Tiger, but I ran it on Leopard, and its just fine. Don’t forget to allow it to create links in /usr/bin for ease of use.
After that, you will need to install glib. But to get glib going, you need some dependencies:
Installing them is simple: untar (tar -zxvpf package.tar.gz), ./configure, make, then a sudo make install.
Now, the README file or the instructions on the wiki will just work. I have several MySQL installations, so I preferred to specify what cmake found. I did this by:
cmake -D MYSQL_DIR:PATH=/usr/local/mysql/ -D GLIB_DIR:PATH=/usr/local/lib/glib-2.0/ .
Then a simple make, and you can go on and try the examples, in examples/. Try the connect application to make sure things are working. You will probably run into a snag though:
luna:examples ccharles$ ./connect
Connector/C++ connect basic usage example..
ERR: MySQL_DbcException in /Users/ccharles/code/mysql_connector_cpp_1_0_0_preview/examples/connect.cpp((function n/a)) on line 159
ERR: Cannot connect (MySQL error code: 0 )
Take a look at examples/examples.h, and look at the connection properties. It uses the test database, on localhost (127.0.0.1), standard port 3306, user is root, and the default password set there is root too. This may not be the commonest setting, so don’t hesitate to change the password or leave it blank (ala a default install), and rerun make. The sample applications will now work :)
Congratulations to Andrey, Ulf, and the rest of the connectors team in getting this going!
Do you use mod_auth_mysql, the Apache module that allows authentication of users to happen through a MySQL database?
If so, the nice folk at Automattic (makers of fine blogging software like Wordpress) have released a patched version that works with phpass.
With this, you can now have single sign on (SSO), with authentication against a WordPress blog (or bbPress forum). Note that WordPress (in 2.5 and later), doesn’t use MD5 hashes to store passwords any longer; instead they are salted and hashed with the phpass library. The Automattic folk use this to provide SSO for Trac and Subversion.
Read Barry’s announcement, and grab the patched mod_auth_mysql.
Presented by Ronan McBrien and Sourath Roy, both from Sun Microsystems. The highlight of the show for me? Seeing the Sun Media Receiver. Not much information about it, except from the Sun Labs Open Day.
Presented by Jonathan Haslam, Simon Ritter, Sun Microsystems
In what I thought was completely great showmanship between Jonathan Haslam and Simon ritter, it was simply, pure comedy, having the two of them on stage. No reason to go deeply into notes (as the verbose slides are available), but the actual demonstration, the writing the code on stage, and the dynamics between the two – that made this session pure gold to attend.
You can ask a system to panic with DTrace if you want!
Some terminology:
DTrace has a PID provider, to look at applications based on PID
dvm provider is a java.net project to add DTrace support in. Install a new shared library, and make sure its in the path.
DTrace in JDK6 exists as a hotspot provider. No need to download a shared library. Its also more feature-rich.
Project DAVE (DTrace Advanced Visualisation Environment) was demoed. Also note that there’s chime.
