Establishes proc as the handler for tracing, or disables tracing if the parameter is nil.

Note: this method is obsolete, please use TracePoint instead.

proc takes up to six parameters:

• an event name

• a filename

• a line number

• an object id

• a binding

• the name of a class

proc is invoked whenever an event occurs.

Events are:

c-call

call a C-language routine

c-return

return from a C-language routine

call

call a Ruby method

class

start a class or module definition),

end

finish a class or module definition),

line

execute code on a new line

raise

raise an exception

return

return from a Ruby method

Tracing is disabled within the context of proc.

  def test
    a = 1

  set_trace_func proc { |event, file, line, id, binding, classname|

  }

Counts objects size (in bytes) for each type.

Note that this information is incomplete. You need to deal with this information as only a HINT. Especially, total size of T_DATA may not right size.

It returns a hash as:

{:TOTAL=>1461154, :T_CLASS=>158280, :T_MODULE=>20672, :T_STRING=>527249, ...}

If the optional argument, result_hash, is given, it is overwritten and returned. This is intended to avoid probe effect.

The contents of the returned hash is implementation defined. It may be changed in future.

This method is only expected to work with C Ruby.

Counts objects for each T_DATA type.

This method is only for MRI developers interested in performance and memory usage of Ruby programs.

It returns a hash as:

{RubyVM::InstructionSequence=>504, :parser=>5, :barrier=>6,
 :mutex=>6, Proc=>60, RubyVM::Env=>57, Mutex=>1, Encoding=>99,
 ThreadGroup=>1, Binding=>1, Thread=>1, RubyVM=>1, :iseq=>1,
 Random=>1, ARGF.class=>1, Data=>1, :autoload=>3, Time=>2}
# T_DATA objects existing at startup on r32276.

If the optional argument, result_hash, is given, it is overwritten and returned. This is intended to avoid probe effect.

The contents of the returned hash is implementation specific and may change in the future.

In this version, keys are Class object or Symbol object.

If object is kind of normal (accessible) object, the key is Class object. If object is not a kind of normal (internal) object, the key is symbol name, registered by rb_data_type_struct.

This method is only expected to work with C Ruby.

Counts objects for each T_IMEMO type.

This method is only for MRI developers interested in performance and memory usage of Ruby programs.

It returns a hash as:

{:imemo_ifunc=>8,
 :imemo_svar=>7,
 :imemo_cref=>509,
 :imemo_memo=>1,
 :imemo_throw_data=>1}

If the optional argument, result_hash, is given, it is overwritten and returned. This is intended to avoid probe effect.

The contents of the returned hash is implementation specific and may change in the future.

In this version, keys are symbol objects.

This method is only expected to work with C Ruby.

Canonical Ordering

Returns the max number of flags interned to symbols.

Sets the max number of flags interned to symbols.

Munges ary into a valid Tuple.

Ensures hash is a valid Tuple.

Delete tuples which dead tuples from the TupleBag, returning the deleted tuples.

Adds a runtime dependency named gem with requirements to this gem.

Usage:

spec.add_runtime_dependency 'example', '~> 1.1', '>= 1.1.4'

Return currently unresolved specs that contain the file matching path.
