*emacs vs. MacFUSE/sshfs

*emacs vs. MacFUSE/sshfs

[David Reitter]

I think this would have to be addressed on the Emacs level. I'm  
cc'ing the Emacs Bugs list.

PS.: You could use Tramp for the time being.

There appears to be a work-around that can be implemented in MacFUSE,
but it also appears emacs is aggressive/optimistic, and this might
affect other filesystems, not just MacFUSE-based ones.  A different
duration for the alarm signal might make sense on the Mac.

Editing remote files via sshfs in Aquamacs would be sweet.

Thanks,

Could you explain more about "it appears emacs is
aggressive/optimistic"?  In the Carbon port, the SIGALRM duration is 2
seconds by default and it's not too frequent.  If some file operation
takes much more time than that period, then it is desirable that it
works with signals so users/applications can interrupt the long
operation, IMO.

You can set it via `polling-period' if you need.

What kind of change on the Emacs side are the MacFUSE developers
suggesting?

I passed the question along to them.  I'll update here when I get  
something useful.

Thanks,
