That's a Symbol up there; the new BleakHouse walks the sym_tbl as well as the regular heap. We now track the history of every individual object instead of just class counts. This means we can accurately (fingers crossed) identify where lingering objects were spawned.
On the flipside, analyzing the log file is slow (a decent-sized logfile will have hundreds of millions of rows). I wrote a pure-C CSV parser, which helps, and there's always the "better hardware" answer. I've been mainly running it on my Mac Mini; if I use the Opteron 2210 it goes much faster, since the analyzer is CPU-bound.
It doesn't make pretty graphs anymore but I'm not sure exactly how they would help. It would be easy enough to add them back.

A gem, not a plugin, because it needs to compile a C extension. First, uninstall the old versions to prevent version problems:
sudo gem uninstall bleak_house -a -i -x
Now:
sudo gem install bleak_house
Also, you need to rebuild your ruby-bleak-house binary, even if you already have one. Just run:
bleak --build
The RDoc has updated usage instructions.

I just want all you programmers out there to know just how hard this guy works, and how little time I get to actually see him. For the good of the cause I guess…. ;-)
Is it 3.2 or 3.0.2?
Still cant find on gem mirrors…
Karl: Use the direct links to the two gems, above. 3.2 is the latest. I’ve filed a Rubyforge ticket about the mirrors being messed up.
Martha: Soon ;)
evan: Make sure you remove that “anonymous girlfriend” spam… :P
Oh, snap!
By the way, the gem mirrors are fixed.
Evan: Line 42 in build.rb is a tiny bit mangled:
exec(“rm #{binary}; cp ./ruby #{binary};
chmod–755 #{binary}; echoe \” Done\"")
chmod doesn’t need ‘–’ and echoe is the olde fashioned command, nowe deprecated :)
One other thing, wget doesn’t exist on my mac–no prob, I modded it to use curl–but you might want to use curl by default.
Oops! Fixed in trunk. I’ll switch to curl, too.
There’s another bug in the queue, so once I fix that, I’ll update the gem.
ld is throwing up errors when it tries to make bleak_house. Here’s the error: http://pastie.caboo.se/102696
Ideas?
Ah; crap; ld is trying to link against the generic ruby binary rather than the ruby-bleak-house one.
I’ll figure something out.
Actually, it looks like you’re using Leopard? I don’t know how to fix compilation against the bundled package (also, I don’t have Leopard). If you install Ruby from MacPorts you should be ok.
Just thought I’d tell you that on my system (Ubuntu) I had to remove the ‘&’ characters from the system calls in “/usr/lib/ruby/gems/1.8/gems/bleakhouse-3.2/lib/bleakhouse/support/build.rb” to be able to use “bleak—build”. The ‘&’ forks the command so that the script continues without waiting for the command to complete, which causes the following commands to fail.
Strange that &> would background rather than redirect STDERR. Are you not using Bash, maybe?
I was able to successfully install bleak_house on my main dev machine running Tiger.
You’ve got 2 weeks to release a version that’s Leopard compatible. :-P
I think you mean, Apple has two weeks to make sure the Leopard Ruby build isn’t confused like the Tiger one was. :)
Yes, I am using bash, so my conclusion would be that the ruby interpreter uses another shell.
Hmm, well, I definitely can’t reproduce it. What does ruby –e ‘puts `env | grep SHELL`’ say? And perhaps bash —version?
I changed the &> in BleakHouse 3.3 to > and 2>&1; maybe that will work better for you.
I think that it might have to do with leopard building things universal by default... I'm not sure. But even with ARCHFLAGS="-i386" it's not happy.

I'm getting this error when trying to use it with Rails Edge:
/var/www/apps/XXXX/releases/20071130025107/vendor/rails/activesupport/lib/
active_support/core_ext/module/aliasing.rb:31:in

from /usr/lib64/ruby/gems/1.8/gems/bleak_house-3.5.1/lib/bleak_house/
rails/action_controller.rb:9
Any ideas?
Please report these bugs on the forum; it's easier to handle them there.

I think the RubyGem mirrors may be behind. It shows up when searching
But fails to install…
Come on Rubyforge! I only have so long on lunch!
