Re: Status of HFS+ support (was hfs support for blocksize != 512)

Hi,

Im currently working on HFS+ support. Im assisted by Brad Boyer
(flar@pants.edu) . I currently target a remake of the hfsutils
originally created by rob@mars.org.

Great to hear. :-)

On the other hand: The hfs acces is normally not needed for heavy
concurrent acces. (Mhh, there might be AFP Servers publishing HFS
partions) For now it should be enough to have a global update
lock on the root of the node. Im not firm with kernel code yet, dont
ask me about the details :-)

Usermode and kernelmode implementation are two quite different things. I
know that from affs. Lots of things you can easily do in user space are
hard to do in the kernel, e.g. you have no virtual memory (so you to take
care not to waste too much memory), you are limited to page (cache) size
and of course all the possible, funny races in the kernel...

BTW do you plan a hfsck? I started more a hfsdump to better see and
understand the fs structure, that could be extended with consistency
checks and maybe later with repair functionality...

bye, Roman
