That says what I was trying to far better than I could. Thanks.

We crossed posts, so I'll repeat the URLs from my previous try last year:

   <http://svn.haxx.se/users/archive-2007-10/0052.shtml>
   <http://svn.haxx.se/dev/archive-2007-10/0083.shtml>

The usual resolution is that the unix guys say "can you just write a
wrapper for your non-standard OS and doesn't fit our design?" and the
Mac guys give up and call the unix guys dismissive. ;-)

We discussed in great detail agreed to let it lie until 1.5 shipped
-- so I'm bringing it up again a year later.

(re-ordering replies slightly for clarity)

That was my argument -- it's a solution, it exists, and it doesn't
interfere with other platforms. For Mac OS, this has been well
defined for years (like 20).

In general, I would argue that the general form is that there should
be code in each platform client to save/restore that platform's
unique attributes.

Also, things like file creation and modification dates might want to
be synthesized from the repository.

This doesn't rule out cross-platform attributes -- an example being
that symlinks/aliases/shortcuts within a repository could be detected
stored in an canonical form (probably relative symlink), but that is
a separate discussion.

A slight generalization on Matt's patch would be to call listxattr()
on Mac OS X 10.4 and newer and save/restore all extended attributes
possibly with with an "xattr:" prefix with some glue for pre-10.4
(note that there's slight overlap between appledouble and xattr,
notably com.apple.FinderInfo).

Cheers,

-Steve
