Issue #3013 has been updated by Markus Roberts. Status changed from Needs more information to Accepted Assigned to changed from Ricky Zhou to Markus Roberts
On IRC Ricky came up with this example of sysread returning an EINTR
#!/usr/bin/ruby
trap(:USR1) do
puts "Caught SIGUSR1"
end
r,w = IO.pipe
puts Process.pid
r.sysread(1)
and also noted that the same problem, at least potentially, exists in the
SELinux code (where it reads /proc/mounts).

Bug #3013: util.rb:execute broken on Ruby <1.8.3
http://projects.reductivelabs.com/issues/3013
Author: Ricky Zhou
Status: Accepted
Priority: Urgent
Assigned to: Markus Roberts
Category: exec
Target version: 0.25.3
Affected version: 0.25.2
Keywords:
Branch:
Apparently the patch in ticket #2731 introduced one more issue by using
readpartial, which isn't available until ruby 1.8.3 (RHEL4 at least is
affected). I'm not sure how this is normally handled in ruby, but if the
readpartial function is not available, the code should fall back to sysread
(along with some code for handling EINTR).
Anybody with better ruby knowledge know how this should be done?
