ruby-dev summary 26662-26760

[Minero Aoki]

Hi all,

This is a summary of ruby-dev ML in these days.

[ruby-dev:26628] show information of --enable-pthreads

Hidetoshi NAGAI proposed a patch which reports that the working ruby
was compiled with --enable-pthreads option or not. Matz suggested
adding a new option, which prints all configure options.

[ruby-dev:26711] --with-static-linked-ext and require

IWATSUKI Hiroyuki reported a static linking related problem. With
--with-static-linked-ext, ruby cannot load xxx.rb when xxx.so is
static-linked:

$ ruby-1.9.0 -e '
p $".include?("openssl.so")
p require("openssl") # should require openssl.rb...
'
true
false # but not loaded.

This bug is fixed by Nobuyoshi NAKADA.

[ruby-dev:26723] reducing #coerce calls

Tadashi Saito posted a patch which reduces Fixnum#coerce calls in
numerical calculation. This patch doubles calculation speed on
average. Matz accepted this patch.

[ruby-dev:26743] zsuper with optional arguments

Hiroshi NAKAMURA reported a difference of "super" between Ruby 1.8
and 1.9:

~ % cat t
class Base
def initialize(a = 'base')
p a
end
end

class Derived < Base
def initialize(a = 'derived')
super
end
end

Derived.new(0)

~ % ruby-1.8.2 t
"derived"
~ % ruby-1.9.0 t
"base"

Matz selected 1.8 behavior.

Note that this is known issue; refer ruby-dev summary 23971-24053
([ruby-talk:108967]).

Will this be part of the Config hash in rbconfig? If not, why not?

Nice! It sounds like this is the best kind of performance optimization you
can get: rethinking a problem and reducing unnecessary overhead. I wonder
if this will eventually reduce the complaints from people who benchmark
Ruby against Foo and determine Foo is better because it's slightly faster.

Congratulations to Saito-san.

The problem is that we cannot check consistency between the running
binary and the required rbconfig.rb.
