ulimit alike in ruby?

[Patrick Gundlach]

Dear ruby-hackers,

is there any way to set resource limits in ruby? I am starting a
program (popen) that should not create files > 1 MB, so I think that
the linux/unix syscall setrlimit would be the best way for that.
Sure I can write an sh-wrapper or c-wrapper around the ruby process,
but I'd like to avoid that. But I haven't found any kernel#ulimit or
alike methods in ruby.

You could write an extension in C that calls the setrlimit function.
Have a look at pickaxe and the section named "Extending Ruby".

I haven't tried it though.

Hello Kent,

Check out http://raa.ruby-lang.org/project/rlimit/

rlimit as well as the other project mentioned there
(library/resource) is gone.

But thanks for the pointer, I should look at raa more often.

Thanks for the pointer! That looks doable (just did a quick test).

*hth*,

I think rlimit is what you are looking for. It is
already made. --David Ross

That is what I did now. I always skipped this chapter of pickaxe
'cause I was too afraid of it . Thanks again for your suggestion.

Thanks to David and Andrew for this nice book; I will buy a paper
copy of it when the new edition comes out.

the link to rlimits for you. It is a good library.

files. --David
