Package: unison
Version: 2.9.1-2
Severity: important

Some of the file properties are unavailable on some file systems
(for example fat32 does not support unix permissions) and
it seems unison cannot synchronize such file systems.
When I try to synchronize between ext and fat32,
files are copied from fat32 to ext, but not not from ext
to fat32. I get the following error message:
"Operation not permitted [chmod(/fat32_partition/directory/.#filename.0.unison.tmp)]"
It is even worse when there is a new directory on ext filesystem, because
unison shows the above message in a message box with only "Quit" button
available, so actually it aborts unconditionally.
An additional annoyance is that there are always differences in
file properties, even if the files are the same.
The solution is to ignore unavailable file attributes.

Hello,

This error has been more or less corrected by upstream developper. They
give a more explicit message about the problem and how to solve it:

[BGN] Copying tata from /mnt/home-nfs/gildor/tmp/unison-test to
/media/disk-3/unison-test
Failed: Failed to set permissions of file
/media/disk-3/unison-test/.unison.tata.edc195559b992c55f435fe470f0a7252.unison.tmp
to rw-rw-r--: the permissions was set to rwxr-xr-x instead. The
filesystem probably does not support all permission bits. You should
probably set the "perms" option to 0o1646 (or to 0 if you don't need to
synchronize permissions).

I think this is the more conservative choice.

I close the related bug.

Regards
Sylvain Le Gall
