Puts sometimes gives:in `write': Interrupted system call (Errno::EINTR)

Hugh_Sasse · 6 March 2003 14:45

I sometimes get the error message:
./parallel.rb:465:in `write’: Interrupted system call (Errno::EINTR)
which is actually from a line

465 puts “deassign: job is #{job.inspect}” if @debug

where job is likely to be fairly large.

ruby 1.6.7 (2002-03-01) [sparc-solaris2.9]

It’s rather irritating as it kills my program dead. If I wrap puts

class IO
alias :old_puts :puts
def puts(*args)
m = Mutex.new
m.synchronise {
old_puts args
}
end
end

Is that likely to help? Anything else I can do without breaking up
my data first, and having to reassemble it?

I think I fixed this one in somewhere during 1.7 development. Try
1.8.0 snapshot, if possible.

Sort of further to this, I run my automated build and test on the
latest snapshot, and the results, as well as the script that created
them, are below. HTH

Next job, try my code with this ruby

Ruby replacement for the sed script I could not get to work.

filter = false
filtering_finished = false
ARGF.readlines.each { |line|

if line =~ /^All Tests/
