Does anyone have suggestions for tools that might help tracking down memory
leaks in ruby programs? I've done a bit of searching around and haven't
found anything.



Cheers,

Adam

I don't know about tools, too. But you can cook yourself something with
ObjectSpace. With this at least you can determine object counts and see
whether some class's counts grow beyond bounds.

Kind regards

If you are using Windows there is Ruby Memory Validator at
http://www.softwareverify.com

No Web page to describe it, but you can join the beta here:

the follow code is in the mkmf.rb:

*def checking_for(m)
f = caller[0][/in `(.*)'$/, 1] and f << ": " #` for vim
m = "checking for #{m}... "
message "%s", m
a = r = nil
Logging:ostpone do
r = yield
a = r ? "yes\n" : "no\n"
"#{f}#{m}-------------------- #{a}\n"
end
message(a)
Logging::message "--------------------\n\n"
r
end

*what meaning of the '*f = caller[0][/in `(.*)'$/, 1] and f << ": " #` for vim*'?

pls!

On Linux you can use Valgrind (valgrind.kde.org).

Are you experiencing the leaks when using external libraries or just core
Ruby?
