ZFS is on a completely open source license. Oracle's beef with Google comes from actions that occurred before Java was open sourced. It's hard to see how the two scenarios are even remotely related, other than "Oracle"

A large part of Oracle's case was based on alleging a Google developer had "copied" code that he himself had contributed to Java. I have to say it's made me a lot iffier on contributing to open source projects, or at least those owned by for-profit companies.

That's the same sort of thinking that leads people to condemn Islam for the actions of a few self-proclaimed Muslims.

Just saw a comment in another thread, stating Apple had slipped in improving their Unix layer, and here comes this. New file system is not a joking matter: Microsoft failed to deliver their new FS; Linux took years to go from ext2 to ext3 to ext4, and btrfs is in forever testing; most of *BSD still use their old ones; zfs took decade to become mainstream... The information currently is very scarce on this one, but I…

And Linux has the blessing/curse of having a million distros, each implementing their installer a little differently, exposing subtle bugs and inconsistencies in the FS/bootloader department.

And AFAIK, GNU Grub hasn't done a release in about four years now, and all the distros are using their own, custom beta build of it. It's a bit of a mess.

No checksumming?

I also didn't see any mention of compression. Hopefully those are at least being worked on and just didn't make it into the docs yet.

HFS+ already supports compression and it says APFS would support nearly all of the features of HFS+, so there's hope.

I'm going to be very cynical and say that based on their track record of major OS overhauls I am _not_ looking forward to the bugs and issues that will sneak past their QA. I still have nightmares of all the bugs with their wifi & USB stack changes in the last couple OSX releases. Please Apple, for your own good don't 'move fast and break things' with the filesystem. At the very least it's time for everyone to make sure they have a good backup system in place before touching this thing.

That is really interesting. I recognised with El Capitan that it already defaults to SMB instead of AFP when you don't give a scheme.

It would be really nice is there was a modern file system that "just worked" regardless of device. I'm tired of having exFAT/FAT being the only filesystem I can reliably use on multiple different OS-es painlessly, and even then I can't use it for all the functions of those OS-es (No time machine). Hopefully this will be open enough to enable that, though who knows how it will shake out.

Apple says they intend to open-source the file system in the docs. Open Source : "An open source implementation is not available at this time. Apple plans to document and publish the APFS volume format when Apple File System is released in 2017."

Just like they promised to open source FaceTime and iMessages? Apple has a history of making false promises in regards to open sourcing products.

> FaceTime

They got sued heavily for it. They had to completely change the implementation and it became a non-P2P video chat.

I think they'll only call this 'stable' once they enable it on new iPhones by default. Which might be 2017, 2018, …

It's not HFS. That in itself is a pretty huge advantage.

That's not really a useful statement. HFS+ has worked pretty well for many years and is really well tested. This will be a completely new filesystem, which means it will have lots of new code that can have bugs or incompatibilities with current apps. APFS sounds like it's going to be great, but I think not being HFS is a disadvantage rather than an advantage.

It's tested, so there's less risk of new and unexpected bugs, but the known problems are significant: https://blog.barthe.ph/2014/06/10/hfs-plus-bit-rot/.
