[ruby-core:56798] [ruby-trunk - Feature #6216] SystemStackError backtraces should not be reduced to one line
From:
"thedarkone (Vit Z)" <thedarkone2@...>
Date:
2013-08-24 15:35:00 UTC
List:
ruby-core #56798
Issue #6216 has been updated by thedarkone (Vit Z).
=begin
I'm not sure @matz/@ko1 understood what @postmodern was trying to describe.
Given an (({overlfow.rb})) ruby program:
200.times do |i|
eval <<-RUBY_EVAL, nil, __FILE__, __LINE__ + 1
def foo_#{i}(&block)
foo_#{i+1}(&block)
end
RUBY_EVAL
def foo_200
yield
end
end
def bar
foo_0 { bar }
end
bar
When run on ruby 2.0, this is the output:
vit@localhost ~> ruby -v overflow.rb
ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-darwin12.2.0]
overflow.rb:4: stack level too deep (SystemStackError)
As can be seen, only a single line of backtrace data is provided, thus the only thing that is known - is the stack was blown while executing a (({foo_x})) method, but none of the (({foo_x})) methods are recursive (the real culprit is the (({bar})) method). Debugging an error like that is nigh impossible on Ruby 2.0.
Contrast this with other VMs:
rbx:

----------------------------------------
Feature #6216: SystemStackError backtraces should not be reduced to one line
https://bugs.ruby-lang.org/issues/6216#change-41339
Author: postmodern (Hal Brodigan)
Status: Assigned
Priority: Normal
Assignee: ko1 (Koichi Sasada)
Category: core
Target version: next minor
When debugging "SystemStackError: stack level too deep" exceptions, it is not helpful that the backtrace is reduced to one single line. Most of the time Ruby incorrectly identifies where cycles begin, resulting in an unrelated "file:line" as the backtrace. A more useful behaviour would be to print the last 30 lines of the backtrace, and have the developer identify which "file:line" is causing the cycle. This is similar to how JRuby handles SystemStackError backtraces.
