HFS+ Volumes are wrapped in a HFS-structure for security reasons, you
can
find out about his at some Website at Apple.

I once started doing a set of HFS+ Tools but got stuck due to personal
reasons.
The current state is that _reading_ works and writing works a little
bit.
I'd be happy someone would care about these. There is a (rotten) tarball

at penguinppc.org. I use(d) a CVS Repository at SuSE. Since I just
upgraded
to SuSE 7.3 I might try to build it again.

In case you are interested feel free to contact me.

uh, security reasons?  ive never heard that and can't believe it
provides any sort of real security.  the only motivation ive ever
read/heard about was to keep feebleminded macos users from being
confused and frightened by older versions of MacOS helpfully offering
to erase the HFS+ partitions/disks.

there are plenty of people who seem to care, just none of them a) know
enough about filesystem hacking to help, or b) don't care enough to
want to hack on it.  ;-)

Umm... last I checked, they were wrapped in an "almost" HFS structure so
that older machines whose { firmware, ROMs } didn't support HFS+ could
still boot from them....  Did I miss something?  :-)

No, you didn't ;) In fact, I even think recent MacOS (or is it MacOS X ?)
may create pure HFS+ volumes without the wrapper.

The main reason for the wrapper was for machines running non-HFS+ capable
filesystem to display something (where are all my files gone ?) instead
of proposing you to format the disk, and for the system to be able to
boot from HFS+ since OldWorld ROMs didn't understand it. Basically, the
wrapper contains a slim-fast MacOS System file which contains the necessary
HFS+ support to mount the real volume and continue booting from that.

libXrender bug crashes OpenOffice

[Jason E. Stewart]

Hey All,

While running Kevin Hendrix's build of OpenOffice I kept getting
Abort's for no reason. We've finally limited down to the Xrender
lib. When it's not on my system, OpenOffice runs fine, with it I get
crashes.

Kevin found a bug in the library and fixed it and OpenOffice runs fine
on his system with libXrender installed. I downloaded the latest xlibs
source from sid and checked, but his patch hasn't yet been
included.

Will it be included soon?

Thanks,
jas.

Err... and what does that have to do with Linux/PPC development? ;)

I think this makes sence because with Linux the HFS+ partition on my HD shows
up with the "where are all my files gone?" thing.  (Which BTW dropped me into
xmon when I vim'ed it...)  But the iPod did not show up with anything
intelligable.

Must be that the iPod is "pure" HFS+ when the other is a wrapper.

To quote a pointy eared character "Fascinating."

Thanks for the info,

Perhaps I was mistaken, but I thought that the bug only existed on
PPC. Is this too X-specific and should be posted elsewhere?

BTW how can I reproduce those crashes? No 'success' so far.

At least I didn't see anything PPC specific in the fix you posted.

In particular though, you should submit this in a bug against the Debian
xlibs package for it to be included there.

AFAIK the fix has already been applied to the XFree86 CVS trunk, so it
will be in the 4.2.0 release. Don't know about the 4.1 branch.


PS: No, you can't build only libXrender.
