Nautilus+Unison to remote and local synchronization

Hi all,

The following unison related project was created on Cofundos.org (a platform for describing open-source
project ideas and pooling resources for their implementation):

*Nautilus+Unison to remote and local synchronization* by wladston
Tags: Plugin gnome sync unison nautilus remote_files
http://Cofundos.org/project.php?id=76

Project description: Integrate unison on nautilus, on a transparent way. User should be able to right
click a folder, select "sync", and then choose the remote medium, just like it's done on unison.

User should also mark a sync schedule option when configuring the sync (sync each day, sync each 2 days, sync
on sundays, etc.)

folders with are synced would appear with a different mini-icon (maybe a mirror drawing, or a networking
image or something like). When right clicked, the user should be able to select "configure sync" and edit
the sync options (schedule, and remote location, conflicts, everything from unison)

Nautilus should have a "synced folders" tab on the preference settings, where the user can edit the
profiles and view the current synced folders, much like one can do using unison.

The Nautilus File Manager is a part of Gnome : http://www.gnome.org/projects/nautilus/
And the Unison file synchronizer tool : http://www.cis.upenn.edu/~bcpierce/unison/

More info at: http://Cofundos.org/project.php?id=76

You can support this project by commenting it or bidding for its impementation!

which windows binary to use?

I have the old stable version and am tired to being bit by the
daylight savings bug that disables fastcheck every 6 months. I'm ready
to upgrade, but the list of newer windows binaries has three options
with no indication as to which I should take.

So which is the most stable of the following: 2.26.14, 2.27.47 (beta),
 or 2.28.23 (unstable)?

Bonus: Are there precompiled Linux binaries that are compatible with
any of these versions?

Your help is much appreciated & will also probably help other people
thinking of upgrading.

- Alan.

New archives ar not identical know problem?


Unison folks,

I see in Google lots of people have reported about a known problem where 
you get the message:

Fatal error: Internal error: New archives are not identical.

Does anyone know how to work around this?  Or is there a fix?

I've been using unison a lot lately.  But currently I can't get one 
unison system.prf file to run no matter what I try.

Thanks

Brent Allsop

For me, it turned out that my harddrive was giving up. A couple of weeks 
later I had to buy a new harddrive. First I saw the unison problems. Later 
I couldn't access certain files anymore. Then I knew that I was in trouble. 
After installing the new harddrive the unison problems just went away.

Unison spontaneously stopped working

I have been a happy Unison user for many years.  My main use of Unison
now is for handling filestore consistency between my Ubuntu workstation
and Ubuntu laptops.  I also use it for creating offsite backups from
Ubuntu to Solaris or Red Hat.   All this is working fine -- which is why
I use Unison :-)

I also occasionally have to use Windows :-(  Having managed to get GTK+
installed I can use either the GUI browser or the command line version
that comes with Cygwin.  Because Ubuntu is currently on 2.13.16 (though
the help about screen reports 2.13.15), this is the version I am using
from Cygwin.  Till a few days ago it was all working.  Then after one
sync, I started getting:

	Fatal error: Internal error: New archives are not identical.

I removed all the archive files just in case, and reran, with the same
result.  This happens with both GUI and command line.  I stripped down
the number of paths to two trivial ones, and still I get the problem.  I
ran with -debug all and the result is attached (hopefully this mail list
doesn't remove attachments).

I am assuming that the transfer has resulted in a file on the Windows
box that has a name that means the Ubuntu path and the Windows path can
never be reconciled.  But this is a wild guess.  The real question is
how to find what the problem actually is.

Thanks.

I tried doing a file system and bad block check on the Windows partition
of the disk on my machine and nothing came up.  I got the same thing
happen after.  So if the problem is disk sector related it is not
something that the Windows file system and bad block checker checks
for.

I believe the reason is that the path "home/users/russel/.bazaar/plugins"
exists on one replica but not on the other. This results in Unison
putting an entry for "home/users/russel/.bazaar/" in one of the
archive but not in the other, hence the failure.  (More recent
versions of unison will report a clear error message in this case.)

I believe you are 100% correct :-)

If only I had commented out that line in the paths specification along
with all the others things would have worked and I would have sussed the
solution.  As it is, I didn't, but you spotted the problem anyway, which
is great.  Thank you for taking the time to solve my problem, it is much
appreciated.

I can now sync up the Windows box, do the experiment I need to do and as
soon as possible reboot to a proper operating system ;-)

THanks again.

version mismatch

I'm in a spot.  I like/need the GUI version, my desktop is at a later version, and the server cannot easily be upgraded.

I really wish the "GUI" aspect of Unison was separate from the "protocol" aspect, and/or that the protocol would negotiate, (like say ssh does)....

oh well... <sigh>

If you cannot install anything on the server, then it's indeed difficult. Now you can have several versions of unison coexisting on one machine, and use the servercmd profile preference to choose which one to use. Would this work for you?
