Method: ObjectSpace.trace_object_allocations

Defined in:
object_tracing.c

.trace_object_allocations { ... } ⇒ Object

Starts tracing object allocations from the ObjectSpace extension module.

For example:

require ‘objspace’

class C

include ObjectSpace

def foo
  trace_object_allocations do
    obj = Object.new
    p "#{allocation_sourcefile(obj)}:#{allocation_sourceline(obj)}"
  end
end

end

C.new.foo #=> “objtrace.rb:8”

This example has included the ObjectSpace module to make it easier to read, but you can also use the ::trace_object_allocations notation (recommended).

Note that this feature introduces a huge performance decrease and huge memory consumption.
