eliminate!() click to toggle source

eliminate call info from the call tree. adds self and wait time to parent and attaches called methods to parent. merges call trees for methods called from both praent end self.

end
find_call(other) click to toggle source

find a specific call in list of children. returns nil if not found. note: there can’t be more than one child with a given target method. in other words: x.children.grep{|y|y.target==m}.size <= 1 for all method infos m and call infos x

# File lib/ruby-prof/call_info.rb, line 62
def find_call(other)
  matching = children.select { |kid| kid.target == other.target }
  raise "inconsistent call tree" unless matching.size <= 1
  matching.first
end
merge_call_tree(other) click to toggle source

merge two call trees. adds self, wait, and total time of other to self and merges children of other into children of self.

# File lib/ruby-prof/call_info.rb, line 69
def merge_call_tree(other)
  # $stderr.puts "merging #{self}\nand #{other}"
  self.called += other.called

  other.children.each do |other_kid|
    if kid = find_call(other_kid)
      # $stderr.puts "merging kids"
      kid.merge_call_tree(other_kid)
    else
      other_kid.parent = self
      children << other_kid
    end
  end
