File object opened via SSH is inconsistent with the file object API. Seek and write return nothing

[mxmlnkn]

This is kind of a duplicate of the paramiko issue. But, I think it could also be fixed in fsspec. I'm not sure whether fsspec does define a standard for the file object. If not, maybe it should? I find it highly unexpected that for the file object:

• seek does not return the new position
• write does not return the number of bytes written
• probably other issues?

This could be fixed here instead of upstream by adding a small wrapper around the paramiko file object. Of course, the same discussion about fsspec/sshfs applies here.

I'd be happy to see the file object wrapped.

Right, any fixes here might end up waster effort. I take it sshfs already fills out the file API?

Yes, it inherits from IOBase and then simply redirects to the asynchssh's seek and write, which are sufficiently compatible.
