nautilus-compare does not work with sftp mounts

Thanks. Patch works nicely. Dont know why obviously nobody else cares ?

sftp mounts, I imagine, are fairly rare - NFS and SAMBA being much more
common

Thanks for fixing

I have problem using GIO URIs for SFTP mounts with meld:

$ meld "sftp://user@server/home/filename1.txt" "sftp://user@server/home/filename2.txt"

* "[Errno 2] No such file or directory: 'sftp://user@server/home/filename1.txt'"
* "[Errno 2] No such file or directory: 'sftp://user@server/home/filename2.txt'"

However meld seems to support GVFS style URIs:

* "/run/user/1000/gvfs/sftp:host=server,user=user/home/filename1.txt"

Am I missing something here? How did it work for you? Does it still work? Do I need special version of meld for it? I am using meld 1.8.4 on Ubuntu 14.04 at the moment.

Yes, it seems meld 3.12.3 handles these URIs, however it's not default on Ubuntu 14.04. I cannot really find our when was this feature added to meld, so it's hard to add this new feature starting from certain version number. Any ideas about that? This seems to be bit connected, but I'm not sure:

* https://git.gnome.org/browse/meld/commit/?id=f236b50f649b0b55f3bda7ef201d7b76b55ab1d5

If I try compare GIO URI [1] with meld 3.12.0, I get an error on Ubuntu 14.04:

Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/meld/meldapp.py", line 73, in do_command_line
    tab = self.parse_args(command_line)
  File "/usr/lib/python2.7/dist-packages/meld/meldapp.py", line 316, in parse_args
    focus=i == 0)
  File "/usr/lib/python2.7/dist-packages/meld/meldapp.py", line 148, in open_files
    return window.open_paths(paths, **kwargs)
  File "/usr/lib/python2.7/dist-packages/meld/meldwindow.py", line 729, in open_paths
    paths, auto_compare=auto_compare, auto_merge=auto_merge)
  File "/usr/lib/python2.7/dist-packages/meld/meldwindow.py", line 667, in append_diff
    dirslist = [p for p in paths if os.path.isdir(p)]
  File "/usr/lib/python2.7/genericpath.py", line 41, in isdir
    st = os.stat(s)
TypeError: coercing to Unicode: need string or buffer, NoneType found

So it seems I need to package the feature to support meld from 3.12.1, which is also the one that is in current Debian stable and is reported to support GIO URIs.
