Gee. Nobody really does much maintenance work on hfs/hfsplus any more.
I cc'ed the ppc guys as I expect that most HFS users are over there.
It seems like a pretty gross failure - others should be hitting it.
I wonder if it's a weird interaction with the loop driver.

Right.
I think that I could run some stress tests (say, like the exhaustive
regression tests that the ntfs-3g developers use), just to get some
basic functionality on HFS+ working.

Thanks once again, Andrew.

Just to make it clear: the reason why I loop-mounted the filesystem was
just to work with a low-risk situation and submit the image to the
recently "ported" fsck, just to get a little bit more confidence that I
didn't mess with the userspace side of things.
But, then, this surprise.
I had some minor inconsistencies with the HFS+ driver in the past, but
they were fixed by running the fsck.hfsplus that I packaged and I didn't
bother reporting it before. My mistake. :-(
Thanks, Rogério Brito.

I can explain the ls output in a very generic sense. This is what you
get if the lookup fails on a name returned by a readdir. I suspect
that creating hard links is failing in some way. In particular, the
"hidden dir" mentioned in the log is used to save the real files for
hard links.
As a quick explanation, HFS+ doesn't have a real concept of hard
links. Apple hacked it in after the fact. The way it works is that
there is a special hidden directory, and the real catalog entries
that match the real names are just references to the hidden file.
Both HFS and HFS+ have no separate notion of directory entries and
inode data. The metadata is stored in records keyed by file name.
Hard links were added after I stopped working on the HFS+ code, so
I don't know it in detail. I know it works for reading hard links,
but I never actually tried creating more links.

Is Roman Zippel still around ? (I added him to the CC list). AFAIK, He
maintains HFS and HFS+ (and was the last one to do any major work on
them).
