Summary: RubyGems does not work properly with upcomming Ruby 1.9.2
Initial Comment:
With ruby ruby 1.9.2dev (2009-10-07) [i386-mswin32_90], coming from
win32-unicode-test branch, RubyGems does not work properly anymore. The problem
is in initialization of system_config_path variable. The original code is:
system_config_path =
begin
require 'Win32API'
CSIDL_COMMON_APPDATA = 0x0023
path = 0.chr * 260
SHGetFolderPath = Win32API.new 'shell32', 'SHGetFolderPath', 'PLPLP', 'L',
:stdcall
SHGetFolderPath.call nil, CSIDL_COMMON_APPDATA, nil, 1, path
path.strip
rescue LoadError
'/etc'
end
but it should be replaced by the following version:
system_config_path =
begin
require 'Win32API'
CSIDL_COMMON_APPDATA = 0x0023
path = 0.chr * 260
SHGetFolderPath = Win32API.new 'shell32', 'SHGetFolderPathW', 'PLPLP',
'L',
:stdcall
SHGetFolderPath.call nil, CSIDL_COMMON_APPDATA, nil, 1, path
path.force_encoding('UTF-16LE').encode!('UTF-8')
path.strip
rescue LoadError
'/etc'
end
i.e. the wide version of SHGetFolderPath should be used. However this code
should be probably specific for specific Ruby versions.
The problem can be reproduced for example on czech windows XP, where the method
SHGetFolderPath returns following string: "c:\Documents and Settings\All
Users\Data aplikací" ("c:\Documents and Settings\All Users\Application data" in
EN windows), with US-ASCII encoding, which is completely wrong.

Message:
Also, use dl instead of Win32API, as Win32API is deprecated.
And Luis, why not have one case for 1.8 and one for 1.9 here?

Message:
You're correct.
We can't implement Wide characters API as Ruby 1.8 do not support encoding in
the same way 1.9 does.
A workaround will be use Win32API completely for the encoding translation, but
I'm having hard time finding that right now.
