xattrs problems on Mac OSX with resource forks

I am using the latest 3.0.0cvs  protocol version 30 Capabilities: 64- 
bit files, 32-bit system inums, 64-bit internal inums,
     socketpairs, hardlinks, symlinks, IPv6, batchfiles, inplace,  
append, no ACLs, xattrs
xattrs  cvs 1.77

I installed xattr for Mac OSX

Senario:
$ mkdir /Users/alan/Desktop/folder1
$ echo 'Hello' > /Users/alan/Desktop/folder1/file1
$ xattr --set color blue /Users/alan/Desktop/folder1/file1

In the Finder.app  I set file1 to the color green.
Drag a bit of text 'details' to folder1 to give /Users/alan/Desktop/ 
folder1/details.textClipping

$ xattr --list  /Users/alan/Desktop/folder1/*

/Users/alan/Desktop/folder1/details.textClipping

xattrs problems on Mac OSX with resource forks

I'm still finishing up this improved xattr implementation, but it's
getting pretty close to being in a good state.  I just checked in a
new version of the patch a little bit ago with some more fixes, but I
don't know if it will improve things for this particular problem.  I
should have a way to test Mac OS X soon, so I'll be able to track down
these issues at that point.
> And finally, the time on the TextClipping has changed
Yeah, that's a known bug in the xattr code where the time gets changed
due to an xattr change on the file.  I haven't gotten around to fixing
it yet, but it's on my list.

Thanks for testing!

This turned out to be a general problem with the requesting of truncated
xattr values for new files.  I just checked-in a fix for this to the
xattrs patch.  I also added a test for this to the testsuite file.
> And finally, the time on the TextClipping has changed
I fixed this a little bit ago.

So, things are looking better now.  Let me know if you find any more
problems.
