[jruby-dev] [jira] (JRUBY-6820) Unexpected behavior of IO.popen when giving arguments as an array containing strings

[Naohisa Goto (JIRA)]

Naohisa Goto created JRUBY-6820 Unexpected behavior of IO.popen when giving arguments as an array containing strings Issue Type: Bug Affects Versions: JRuby 1.7.0.pre1 Assignee: Thomas E Enebo Created: 06/Aug/12 9:21 AM Description: In IO#popen, to bypass the shell for avoiding messy shell escaping and potential security hole, giving command-line as an array containing string objects is available since Ruby 1.9. However, on JRuby, when passing arguments with shell special characters to IO#popen, whole arguments seem to be omitted. $ jruby -v -e 'p IO.popen(["/bin/echo", "(a)", "*" ], "r+") { |io| io.read }' jruby 1.7.0.preview1 (ruby-1.9.3-p203) (2012-05-19 00c8c98) (OpenJDK 64-Bit Server VM 1.6.0_20) [linux-amd64-java] "\n" In MRI, the /bin/echo works correctly. $ ruby -v -e 'p IO.popen(["/bin/echo", "(a)", "*" ], "r+") { |io| io.read }' ruby 1.9.3p253 (2012-07-04) [x86_64-linux] "(a) *\n" Project: JRuby Priority: Major Reporter: Naohisa Goto
