Process.setrlimit question

Ruby
1

why does this not blow up?

cfp:~ > cat a.rb
require ‘yaml’

factor = 100000000000000000

soft, hard = Process.getrlimit Process::RLIMIT_RSS
y ‘soft’ => soft, ‘hard’ => hard

Process.setrlimit Process::RLIMIT_RSS, soft/factor, hard/factor

soft, hard = Process.getrlimit Process::RLIMIT_RSS
y ‘soft’ => soft, ‘hard’ => hard

s = 42.chr * (soft + 1)
s[-1]

cfp:~ > sudo ruby a.rb; echo $?

hard: 9223372036854775807
soft: 9223372036854775807

hard: 92
soft: 92
0

i sort of expect this to get signaled and throw an exception?

cheers

setrlimit() doesn’t work on OS X.

well gosh - that’d explain it - doh! :wink:

seriously though - you’d think it’d throw like fork does on windows
though eh?

You would think. I’ve hit other situations like this with OS X, too. :frowning:
