Hi Dm,

Is there any different in the way sbbs handles LFN with addfiles under Windows and Linux?

I have files on a FAT32 filesystem mounted on my linux box and ls handles the LFN/SFN conversion nicely.

bbs@bbs:/sbbs/data/dirs/bbs/bbc/games/arcade$ ls -l MoonLand*
-rwxr-xr-x 1 bbs bbs 2753 May 10 00:28 MoonLander-2.zip
-rwxr-xr-x 1 bbs bbs 2736 May 10 00:28 MoonLander.zip bbs@bbs:/sbbs/data/dirs/bbs/bbc/games/arcade$ ls -l MoonLa~1.zip
-rwxr-xr-x 1 bbs bbs 2753 May 10 00:28 MoonLa~1.zip bbs@bbs:/sbbs/data/dirs/bbs/bbc/games/arcade$ ls -l MoonLa~2.zip
-rwxr-xr-x 1 bbs bbs 2736 May 10 00:28 MoonLa~2.zip bbs@bbs:/sbbs/data/dirs/bbs/bbc/games/arcade$

However when I try to import using addfiles, I get something rather different:

I would expect it to be creating short names.

Maybe you have a conversion for Linux users so they can addfiles and have them converted automatically.

If that's the case, any way to turn that off so I can see how it would work by letting the OS do the filename conversion? If that makes sense?

Thanks,
Nigel

Hi Dm,

Is there any different in the way sbbs handles LFN with addfiles under Windows and Linux?

Yes. Synchronet doesn't actually store LFN's, so it requires an OS API to translate between and short and long filenames. *nix OSes don't have such an API.

I have files on a FAT32 filesystem mounted on my linux box and ls handles the LFN/SFN conversion nicely.

I would expect it to be creating short names.

addfiles would have to call an OS function to get the short filenames. I know of no such API/function for Linux.

Maybe you have a conversion for Linux users so they can addfiles and have them converted automatically.

If that's the case, any way to turn that off so I can see how it would work by letting the OS do the filename conversion? If that makes sense?

The OS (or file system driver) is determining what the actual short filename will be. I would need a programmatic method of querying what that short filename is.

Yes. Synchronet doesn't actually store LFN's, so it requires an OS API to translate between and short and long filenames. *nix OSes don't have such an API.

I was hopeful that the kernel would take care of that on the linux side too, since I can write a long filename and then read it by the short filename using regular unix commands.

addfiles would have to call an OS function to get the short filenames. I know of no such API/function for Linux.

Would anything out of https://github.com/torvalds/linux/tree/master/fs/fat
be useful? There's stuff about long and short filename conversion in there.

Not sure if there's anything I can provide to help?

There's no unix command (or standard API) to say "give me the short name of this file".

addfiles would have to call an OS function to get the short filenames. I know of no such API/function for Linux.

Looking at the mdir source now. I suppose you could play with mdir a bit. I don't have any vfat partitions mounted, so I can't immediately play with it.
