[MacOS] DwarFS mount not seen through Finder

[rraihansaputra]

On mounting a valid DwarFS file, the files and directory can be seen on terminal and other programs (ex: VSCode) but Finder only shows the top level directories and no files.

Can provide more data/debugging if needed. AFAIK this relates to the communication between MacFUSE and DwarFS.

Hi and thanks for your feedback!

This is really odd. TBH, I'm not sure if I've notice this before, but I can definitely reproduce it here to some extent (I can see all directories, not only top level, but no files / links). I have absolutely no idea why this is happening.

I'd definitely appreciate any hints as to what could be missing in the interface between DwarFS and macFUSE.

I likely won't have time to dig into this myself before next week.

I've found the problem: the getxattr() call works quite differently on Linux and macOS.

On Linux, getxattr() returns ENODATA if an attribute doesn't exist, and that's also what the DwarFS FUSE driver returns.

On macOS, it is expected to return ENOATTR if an attribute doesn't exist. The macOS call doesn't even list ENODATA, at the same time, ENOATTR doesn't seem to exist on Linux.

This will be fixed in the next release.

You can actually work around the problem by using macFUSE's noapplexattr option, i.e.:

dwarfs image.dwarfs mountpoint -o noapplexattr

This should be fixed in v0.9.8, please re-open if there is still a problem.

Thank you for the quick response and the fix!
