This gem introduce several methdos to
ObjectSpace to operate all of iseq objects in a process.
Ruby (MRI) 2.2 and erlier, all of bytecode (iseq: instruction sequence) are
RubyVM::InstructionSequence objects and we can touch them with
However Ruby 2.3 and later does not expose iseqs by
RubyVM::InstructionSequence. You need to use
RubyVM::InstructionSequence.of(proc or method object) to get
RubyVM::InstructionSequence and it is impossible to get all of iseqs in a process.
This gem provides
ObjectSpace.memsize_of_all_iseq to get all of iseqs in a process for Ruby 2.3 and later. Future Ruby version can provide same purpose API, but not sure.
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install iseq_collector
require 'iseq_collector' adds the following singleton methods to
ObjectSpace.count_iseq #=> Integer
ObjectSpace.memsize_of_all_iseq #=> Integer(this feature can be implemented by
