Bug #14505
Updated by lionel_perrin (Lionel PERRIN) almost 7 years ago
The following ruby code never returns ~~~ ruby `ruby -r oci8 -e puts 'hello'` # this never returns too: IO.popen(%w(ruby -r oci8 -e)+["puts 'hello'"]) { |o| puts o.read } # and this never returns too is blocked too: Open3.capture2(*%w(ruby -r oci8 -e)+["puts 'hello'"]) # and this is blocked too ~~~ while its python equivalent runs successfully ~~~ python import subprocess subprocess.call(['ruby', '-r', 'oci8', '-e', 'puts "hello"']) ~~~ The issue seems to require some 'unusual' context to be triggered. The ruby-oci8 (https://github.com/kubo/ruby-oci8) gem used by the subprocess loads an oracle dll which seems to open some file descriptors. Anyway, I wouldn't expect the caller to be affected by the libraries loaded by the subprocesses. Thanks for your help, Lionel
