java.io.File

[Jeroen Frijters]

Hi,

I just merged libgcj's Windows support in java.io.File to Classpath's
java.io.File and I noticed two small bugs. Attached is a patch for
gcc/libjava/java/io/File.java that adds support for "\c:" style paths to
normalizePath.

The second issue is a bit subtle. The native Win32 implementation of
getCanonicalPath, will resolve a relative file based on the current
Win32 directory, not the user.dir Java system property. Here's what I
ended up doing:

  public String getCanonicalPath() throws IOException
  {
    // On Windows, getAbsolutePath might end up calling us, so we
    // have to special case that call to avoid infinite recursion.
    if (separatorChar == '\\' && path.length() == 2 &&
	((path.charAt(0) >= 'a' && path.charAt(0) <= 'z') ||
	 (path.charAt(0) >= 'A' && path.charAt(0) <= 'Z')) &&
	path.charAt(1) == ':')
    {
	return VMFile.toCanonicalForm(path);
    }
    // Call getAbsolutePath first to make sure that we do the
    // current directory handling, because the native code
    // may have a different idea of the current directory.
    return VMFile.toCanonicalForm(getAbsolutePath());
  }

Regards,
Jeroen
