IO.open does not seem to work in jruby
--------------------------------------
Key: JRUBY-6225
URL: https://jira.codehaus.org/browse/JRUBY-6225
Project: JRuby
Issue Type: Bug
Components: Ruby 1.8.7, Ruby 1.9.2
Affects Versions: JRuby 1.6.5
Environment: Windows 7 64 bit
Reporter: Stephen O'Donnell
I have some code that works in MRI Ruby, and opens a pipe to processes and then
writes to their standard input.
The following code works in MRI ruby (1.8.7 and 1.9.2) and exits with a zero
(which is set in $?):
IO.popen("mysql -usodonnel -psodonnel", "w") do |p|
p.puts "use sodonnel;"
p.puts "select 1 from duall;"
p.puts "exit"
end
puts $?
However in JRuby 1.6.5, it fails to open any process I attempt, setting 256
into $?. The behaviour is the same with or without the --1.9 switch. No
exceptions are raised except by setting $?.
Is this a bug or limitation? I have not yet tried this on Linux to see if it is
a Windows specific issue.
My JRuby version is:
C:\Users\sodonnel\code\dbgeni>jruby -v
jruby 1.6.5 (ruby-1.8.7-p330) (2011-10-25 9dcd388) (Java HotSpot(TM) 64-Bit
Server VM 1.6.0_29) [Windows 7-amd64-java]
