Set Net::HTTP#continue_timeout AND pass - 'expect' => '100-continue' to a extra HTTP header. - - For example, the following code sends HTTP header and waits for getting - '100 continue' response before sending HTTP request body.

(new characters and scripts) - -* [experimental] Regexps now support Age property. - Unlike Perl, current implementation takes interpretation of the - interpretation of UTS #18. - http://www.unicode.org/reports/tr18/ - -* Turning on/off indentation warnings with directives. - ("# -*- warn-indent: true -*-" / "# -*- warn-indent: false -*-") - -=== Compatibility issues (excluding feature bug fixes) - - * Rational#to_d - - See above. |
