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.

Calls CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON). Starts tracking memory allocations. See also OpenSSL.print_mem_leaks.

This is available only when built with a capable OpenSSL and –enable-debug configure option.

Clear default gem related variables. It is for test

Default options for gem commands for Ruby packagers.

The options here should be structured as an array of string “gem” command names as keys and a string of the default options as values.

Example:

def self.operating_system_defaults

{
    'install' => '--no-rdoc --no-ri --env-shebang',
    'update' => '--no-rdoc --no-ri --env-shebang'
}

The line number in the source code where this AST’s text began.

The line number in the source code where this AST’s text ended.

Initiates the SSL/TLS handshake as a client in non-blocking manner.

# emulates blocking connect
begin
  ssl.connect_nonblock
rescue IO::WaitReadable
  IO.select([s2])
  retry
rescue IO::WaitWritable
  IO.select(nil, [s2])
  retry
end

By specifying a keyword argument exception to false, you can indicate that connect_nonblock should not raise an IO::WaitReadable or IO::WaitWritable exception, but return the symbol :wait_readable or :wait_writable instead.

Returns the error string corresponding to the error code retrieved by error.
