Hi all,


This is a summary of ruby-dev mailing list.


[ruby-dev:22577] modify of rb_class_of

K.Sasada posted a speed optimization patch for CLASS_OF(obj) and
its benchmark trial report, and Matz accepted it. Based on the
idea that the argument of rb_class_of(obj) is not special
constants in most cases, the patch adds "!SPECIAL_CONST_P(obj)"
(or similar statements) to the beginning of rb_class_of(VALUE obj).
You can find the trial report from:

The page above is written in Japanese, but the codes and results
are plain ASCII.


[ruby-dev:22581] [Oniguruma] /a{,n}/

K.Kosako extended Oniguruma's regexp syntax to handle "/a{,n}/"
as equivalent to the expression "/a,{0,n}/" when compiling
Oniguruma with the flag ONIG_SYNTAX_RUBY. To help users just
made a typo and did not mean to use it, Tanaka Akira gave
Kosako patches to raise warnings when the new expression
is used.
