No file descriptor on directories
---------------------------------
Key: JRUBY-3613
URL: http://jira.codehaus.org/browse/JRUBY-3613
Project: JRuby
Issue Type: Bug
Components: Miscellaneous
Environment: $ uname -v
Darwin Kernel Version 9.6.0: Mon Nov 24 17:37:00 PST 2008;

$ jruby -v
jruby 1.2.0 (ruby 1.8.6 patchlevel 287) (2009-03-16 rev 9419) [i386-java]
Reporter: Bram Wijnands
When calling sysopen on a directory i get the following error:
-----
$ jruby irb
irb(main):001:0> IO::sysopen "/dev"
Errno::ENOENT: No such file or directory - /dev
from (irb):2:in `sysopen'
from (irb):2
-----
Is this intended not to work ? When i tried this i assumed everything on the os
was a file and directory where essentially files tagged as directories, Running
this example in CRuby gives me back a file descriptor.
When trying to achieve this with Java integration i run into a strange error.
------
jruby_file = org.jruby.util.JRubyFile.create("/dev/","/dev")
p jruby_file.exists()
flags = ModeFlags.new(ModeFlags::RDONLY)
c = ChannelDescriptor.open("/dev/", "/dev", flags, 0, nil)
p c
------
Will print true and crash right after on creating the new ChannelDescriptor.
Which i find rather strange as it crashes on:
----ChannelDescriptor.java----
JRubyFile theFile = JRubyFile.create("/dev/", "/dev");
.....
RandomAccessFile file = new RandomAccessFile(theFile,
flags.toJavaModeString()); // <---- boom
-------
Isn't this error basiclly something that's been catched earlyer in the method
but gets recreated because the flags are always set to r&w on the
RandomAccessFile ?
( if (theFile.isDirectory() && flags.isWritable()) )
