-------------------------------------
Summary: Ruby does not deal with filesystem unicode chars properly
Key: JRUBY-6664
URL: https://jira.codehaus.org/browse/JRUBY-6664
Project: JRuby
Issue Type: Bug
Components: Encoding
Affects Versions: JRuby 1.6.4
Environment: Windows 7
Reporter: Fabio Zadrozny
I.e.: the code:
org.jruby.RubyFileTest.directory_p(ThreadContext, IRubyObject), which does:
runtime.getPosix().stat(file.getAbsolutePath()).isDirectory()
"No such file or directory" error is thrown.
Internally it does something as LibC.stat(path, fileStat), and apparently the
problem is that the LibC.stat is not converting the java string to the
filesystem encoding properly (note: my guess is that in windows it needs to be
converted to the mbcs encoding, while in Linux the string can probably be used
as is because it's an utf-8 string).
The code below reproduces the error in the same way that
org.jruby.RubyFileTest.directory_p(ThreadContext, IRubyObject) does (but in a
proper test-case).
{code}
import java.io.File;
import junit.framework.TestCase;
import org.jruby.Ruby;
import org.jruby.RubyFile;
import org.jruby.RubyString;
import org.jruby.util.JRubyFile;

public class UnicodeCharsJRubyTest extends TestCase

public void testUnicodeChars() throws Exception
{
File file = new File("unicodeáéíóú");
if (file.exists())
{
if (!file.delete())
{
fail("Unable to delete file: " + file);
}
}
try
{
if (!file.mkdirs())
{
fail("Unable to create directory: " + file);
}
Ruby runtime = Ruby.newInstance();
JRubyFile rubyFile = RubyFile.file(RubyString.newString(runtime,
file.getAbsolutePath()));
assertTrue(rubyFile.exists());
assertTrue(file.exists());
assertTrue(file.isDirectory());
try
{
assertTrue(runtime.getPosix().stat(rubyFile.getAbsolutePath()).isDirectory());
}
catch (Exception e)
{
throw new RuntimeException("Expecting posix layer to work
properly", e);
}
}
finally
{
if (file.exists())
{
file.delete();
}
}
}
}
{code}
