Bug #628: Assigning to $0 truncates value

• Status: Rejected
• Assignee: -
• Target version: -

[mfurr (Mike Furr)]

=begin
Consider the code:
$0 = "abcdefghijklmnopqrstuvwxyz"
puts $0

If I save this in "test.rb" and then invoke: "ruby test.rb", I get:
abcdefghijk

More interestingly is that the level of truncation seems tied to the length of the command line. For instance, running "ruby -r yaml test.rb" outputs:
abcdefghijklmnopq

I'm running 1.8.7p72 (and this seems to be present in earlier versions, such as 1.8.5).

=begin
Not a bug.
$0 rewrites system provided area so that ps command can show it,
and its length is restricted by OS (and command line length on some platforms).
