Any interest in a bounty for a native ext2/ext3 file system?

As was mentioned by Steven Solie at AmiWest I have ported Leif Salomonsson's filesysbox.library and NTFS3G to AmigaOS 4.x rewriting them to make use of AmigaOS 4.x features like mutexes, the new vector port API and replacing some Morphos specific features like utf-8 conversion using charsets.library and usage of deviceio.library (to replace the latter I wrote a disk cache entirely from scratch). Also I have added some entirely new features like being able to rename and format a disk normally which is AFAIK not available in the MorphOS version.

Now that we have filesysbox.library on AmigaOS it should be possible to look at porting of other FUSE file systems:

http://sourceforge.net/apps/mediawiki ... dex.php?title=FileSystems

One in particular that I think would be interesting is this one:

http://sourceforge.net/projects/fuse-ext2/

The code structure is very similar to that of NTFS3G so I expect it should not be too hard for me to port it in the same way I have done NTFS3G. However as it still involves a large amount of work I would be more motivated if there was a bounty for it which is why I'm starting this thread.

As mentioned on the SF.net project page it supports ext2 and ext3 linux file systems (no mention of the latest ext4 though) so it could be useful f.e. for people who have Linux installed on their NG Amigas to exchange data between AmigaOS and Linux installations.

The code for the port will of course be released under GPL license when it is finished.

Please post in this thread you have questions about what I just wrote or if you are interested in donating to a bounty like this.

If it could be use to share easily a partition between AOS and Linux on the same computer.

Sure. I'm interested and I will participate.

Yes it will be useful for me. I will donate some money

I will donate too. Also if you will ever think about fat32, i will donate to port of better implementation too (if it will faster than our current cross-dos, of course as that is main worry about fat32).

I'm also interested in HFS, it seems to me MacOSX is starting is popular, and so it's nice to have HFS for emulators.

I'm interested in both EXT2/3 and HFS so I will support such a bounty.

By the way, many thanks for your effort in porting filesysbox and NTFS-3G to AmigaOS 4.

I could donate about 15euro which i normally do, i donated for about 6 apps last month. NTFS is what i lack most as fat i can already use. For the ext2/ext3/hfs would be a plus. You never know when someone comes with a harddrive/usb stick with a filesystem you normally dont use.

When can we enjoy your ports, is it when os4.2 releases or before ?

For me the EXT2Filesystem (68k) from Aminet works okay.
So it is maybe better to use your time for anything else.
But on the other hand it is always better to have a native version, so i would donate too :)

This file system doesn't support the new 64-bit dos packets so it won't work with files larger than 4 GB.

Sounds like a nice idea to me.

Would a undelete for fat be possible aswell? I'd donate xtra for such a feature.

I will surely donate for such a filesystem, because I need to access my Linux disks, but also because it is (apparently) much more than a straight port from another system.

Do you think you can already share the NTFS3G filesystem?

How fast does your implementation compares to the FUSE driver on Linux on the same computer in terms of performance?

The mentioned 68k implementation is what I use all the time, but for now I'll just say it doesn't work as well as it did. I would donate towards that "OS4" program.

I don't have Linux installed on my Sam so I can't do this comparison but one of the beta testers might be able to.

Kas1e did however do some speed comparisons with CrossDOS and the tests showed that it's very slow when dealing with many small files but it's more than twice as fast as CrossDOS when copying just one big file from RAM:. The bad performance with many small files is as far as I understand something that also Linux users are complaining about and is likely because of the reverse engineered nature of NTFS3G.

I don't need ext2/ext3 but I'd support the bounty to keep the boingball rolling.

Interest seems sufficient so I've posted a bounty suggestion on amigabounty.net for it now:
