[ruby-list:38778] ruby-dev summary 21833-21882 /draft

斉藤です。今週分の ruby-dev summary です。
毎度ですが添削宜しくお願いします。

申し送りは以下です。

* [ruby-dev:21639] load() blocks threadscheduling は
   まだ伸びないのと dRuby などの別案が挙がってる段階なので見送り。
   後でなにか実装が出て新スレッドが立ったら載せたいです。

* [ruby-dev:21879] win32 -r case sensitive はなかださんの
   解説をみると FAQ なようなので、記事としては載せてません。

* 不具合報告と fix らしいのはとりあえず全部抜いてます。
   話題の抜けなどありましたらご指摘歓迎。

できれば火曜、最悪でも水曜には出したいです。
では。

[ruby-dev:21809] lib/test/unit/ui/tk/testrunner.rb

   A new GUI interface for lib/test/unit using Tk extensions
   have been developed by Kazuhiro NISHIYAMA, with help from
   U.Nakamura, Nobu Nakada and Hidetoshi NAGAI.  The TK
   interface almost works well so far if you use a patch
   for pthread by NAGAI(See an article below). Let's try it out.


[ruby-dev:21819] error message of Array.new(9,0) {|x|x+1}

   Take_tk reported a strange error message from Array.new:

     Array.new(9,0){|x|x+1}
       #=> wrong number of arguments (ArgumentError)

   The cause is simple. Array.new takes only 4 styles of arguments,
   an another array, size of array, size and a default value or size and
   a block to generate default values.  In the example above uses 2 
argument
   styles at once and it confuses Ruby, but the error message is a 
little bit
   difficult for us to understand.  Not everyone knows all of 
initialization
   styles and method calling details inside of Ruby.

   Proper English message for this error is wanted.  Fell free to post it
   if you have any idea.


[ruby-dev:21833]
    pthread trouble on tcltklib (Re: ruby-tk hangs when exception is 
raised)

   Hidetoshi NAGAI commited a patch to make pthread and ruby thread works
   well together.  The patch will solve problems in extension libraries
   using pthreads, Tcl/Tk extension for example.  You can try it by 
adding
   "--with-pthread-ext" to configure options. The options is disabled
   by default.
   Nagai said the patch works, but it is just preliminary. Testing with
   other extensions using pthread and sending bug reports are welcome.


[ruby-dev:21846] StringIO#path

   In current implementation, StringIO#path behaves the same as
   StringIO#inspect.  This behavior is to provide polymorphic
   #path operation for applications uses not only File objects
   but also similar IO subclasses.  Nobu Nakada changed StringIO#path
   to return nil because it seems less likely functional for now.


[ruby-dev:21876] get_last_error or getLastError by DL::Importable

  　　　Take_tk found a difference of imported method name between Ruby/DL
   and Appolo.  For instance, When you import GetLastError() from
   kernel32.dll on Windows, Ruby/DL converts its name to "getLastError".
   Meanwhile, Appolo converts it to "get_last_error".

   Takaaki Tateishi, who is the maintainer of Ruby/DL, said that the
   behavior can be changed but he also received a request from who
   wants to use imported method name as-is, "GetLastError" in this case.

   They started talking about how Ruby/DL treat this and how to implement
   it.
