Things to look out for while adding FUSE support to XFSTests

Things to look out for while adding FUSE support to XFSTests

[Bhumit Attarde]

Hello,

I’m a Google Summer of Code[1] student developer at KDE working on
integrating XFSTests with KDE’s KIO-FUSE[2]. KIO is a KDE framework
that provides and implements abstractions for accessing various types
of (virtual) filesystems in a cross-platform way. KIO-FUSE is a
project that lets you mount remote locations on your machine locally
using FUSE. We’re anticipating that integrating XFSTESTS with KIO-FUSE
would help us uncover previously undetected bugs in KIO-FUSE and
KIO-slaves[3] (ioslaves) as well as the various protocols themselves.
You can read a brief summary of the project by visiting the following
link: Integrating XFSTests with KDE KIO-FUSE[4].

As a part of the project, I’ll be adding FUSE support to XFSTests.
While a patch[5] was submitted for this, it seems to be abandoned. I’m
aiming to build on the mentioned patch, improve & test it after
rectifying the errors pointed out by the reviewer. Some main changes
that I will be making are --
I] changing $SUBTYP to $FUSE_SUBTYP
II] removing the added check case in `scratch_cleanup_files()`

Is there anything I should keep in mind or need to look out for while
working on this?

Thank you.

Best,
Bhumit Attarde

You should address this question to the FUSE maintainer who also
happens to be the author of path [5] (CCed).

Thanks,
Amir.

Thanks for picking this up.

I don't have any requirements except that it should work with the
passthrough filesystem found in the libfuse3 source.

Cc'ing fuse-devel to keep the libfuse maintainer in the loop as well.

Thanks,
Miklos
