Bug #3215
Updated by jeremyevans0 (Jeremy Evans) over 4 years ago
=begin This is with a VS8 compiled version of ruby. Given this simple program (foo.rb): ----------->8---------cut--------8<------------ puts "*" * 20 p IO.popen('echo HI') {|f| f.readlines} puts "*" * 20 ----------->8---------cut--------8<------------ I get this: ----------->8---------cut--------8<------------ E:\test>bin\ruby.exe foo.rb ******************** The handle is invalid. [] ******************** E:\test> ----------->8---------cut--------8<------------ Interestingly, if I redirect to a file, it works: ----------->8---------cut--------8<------------ E:\test>bin\ruby.exe foo.rb > q E:\test>type q ******************** ["HI\n"] ******************** E:\test> ----------->8---------cut--------8<------------ I'm not sure what is going on, but I know that the python group had similar problems in python < 2.6.... maybe we can crib their solution?
