Bug #10859: Process.spawn raises TypeError when passing hash with symbols as env

• Status: Closed
• Assignee: -
• Target version: -
• ruby -v: ruby 2.3.0dev (2015-02-17 trunk 49623) [x86_64-linux]
• Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN

[bubo47 (Jakub Jursa)]

expected:

head :001 > Process.spawn({FOO: "bar"}, "bash")
 => 13479 

got in reality:

head :001 > Process.spawn({FOO: "bar"}, "bash")
TypeError: no implicit conversion of Symbol into String
...

when I pass {"FOO" => "bar"} as first parameter, everything works as expected. It would be nice though to have possibility to pass Hash with symbols as parameter (or, at least mention in documentation http://ruby-doc.org//core-2.2.0/Process.html#method-c-spawn that env hash cannot have symbols as keys)
