Neat, where are the sources? Maybe someone wants to compile it for AROS and AmigaOS.

Perhaps it isnt a port of open source but code written from scratch?

Heh, you are right, I guess I'm too used to the normal witchhunt here at ANN.lu.

Hopefully someone with technical skills can ask the author, AROS has lacked a good way of intercommunicating with other filesystems for a while imho.

Nowhere in the readme I spot anything to base your conclusions on!

If it would not be opensource then how do you think it was ported to MOS ?

Ext2 is opensource as are most of the other GNU and linux stuff.

Me speculating that it is based on GPL is totally unfounded and I appologies, for my hasty conclusion. I confused this with something else.

Of course that doesn't mean it would be neat if it could be used with other Amiga clones too ;)

That doesn't help you since Amiga (and presumably MorphOS) filesystem handlers don't work like *nix ones. It still takes a lot of work to make drivers for non-trivial filesystems such as ex2/3 or reiserfs for Amiga or clones.

Its entirely possible this was written from scratch. It may even have been easier than porting it.

OTOH, it may be based on open source code. The only people who know are the people who wrote it..

In reply to Comment 19 (Peter Gordon):
I don't know wether it's completely closed source; however, a quick look at the readme would suggest so. In fact it's just an handler (not a complete filesystem) with read-only support ATM. These and the fact that it uses libDeviceIO (a MOS/Amiga SW) make me think that it might be an original development from scratch, still heavily WIP. If it was a port, I'd be lead to think it would have less MOS specific code/features in it, and would probably be a complete filesystem.
It's a very nice development nevertheless in both cases (be it OSS or closed source). Or am I wrong?
(yes, in case it uses GPL/LGPL code, the source code should be made available, but it's perfectly possible it's closed source)

Kind regards,
Andrea

Couldn't it have been written from scratch? Isn't that the most
preferable for system components like this anyway, I mean, slick and
lean, NATIVE code should give far better performance than ported *nix
code, shoudln't it?

Like the well documented Amiga API made it possible to write
complete new OS's from scratch, such as MorphOS and AROS, wouldn't it
be possible to write a filesystem handler from scratch based on the
well spread ext2 documentation?

Just because AROS is open source doesn't mean that MorphOS or OS4 is
it too, even though they build on the same API. Different code from
different developers achieving the same thing, but still not the same!

Uh, how could EXT2 be "open source"? It's a fileystem format, not a
piece of software. Well.. a filesystem format could be declared under
the GPL, I suppose, as it's not only valid for code. However, this
would then be with respect to modifications etc of the filesystem spec
itself, not of sourcecode capable of understanding the (original
specification of the) format.

Now, I don't really have much of a clue when it comes to filesystems,
but I doubt it's something you "port" easily from a *ix GPL source. To
the best of my knowledge, it's quite different on Amiga-like systems.

In reply to Comment 4 (Nicolas Mendoza):
Even if ext2 has been released as GPL, you can still make a closed source software that can read/write to ext2, as long as you don't use the code that was originally used for ext2. There are such programs already for Microsoft Windows and don't have any leagal problems even if it's closed source.

True, you don't port a linux filehandler easilly, but the core data manipulation code & read code should be portable, it's the interface between the hardware & the rest of the OS that's different.

Well, that's my understanding of it anyway ;)

In reply to Comment 26 (Johan Rönnblom):
.. except if you could GPL a single data structure, all of the whining about
the unfairness of software patents would be totally invalidated.

So you can't just "GPL" the filesystem for sure. As far as I know Marcin coded this all on his own from the (very available) documentation, and not based on any GPL'd code.

Amiga UAE users as WinUAE, Amithlon, LinuxUAE, others UAE and now AROS need several times to access to Linux partitions.
As several a Linux system in installed on their computer.


AND as only 68k AmigaOS 3.X apps can run on these Amiga systems, a 68 k port of that Linux File system will help that Amiga community to get access to their Linux partitions...


I hope you understand, why it is important, if a 68k port is made.


Sincerely

minor nit: UAE on linux doesn't need it. You can set up UAE to simply use the host file system which certainly makes it easier to move files around.

I understood, but there is a mistake.

So please stop put "Amiga" everywhere. The Amiga community = Amiga Classic, Aone and Pegasos users. nothing more.
When you emulate an atari on your pc you don't say "Atari community" so please don't say that for amiga.
