Yeah; I would figure so, too.

what about the      #*.unison.tmp     files ?
don't they get erased  when a new session starts ?

IIRC this does apply to "beta" versions only - the latest stable
(2.9.1) does remove temporary files and folders created by a 2nd
running instance?

Sorry, I'd forgotten about this.  Version 2.9.1 will remove temp files of
other running unison processes during update detection.  2.9.20 and later
versions will remove only temp files associated with the current set of
roots.

Received unexpected header from the server

Hi,

I'm using:
- A Unison 2.9.1 client in a Windows XP platform,
- A Unison 2.9.1 server in a Solaris platform.

The connection from the client to the server is
performed through RSH coming from Cygwin 1.5.5-1 .

As I run the client, I get the following error
message:

<<
[remote] Shell connection: rsh (rsh, republique,
/nfs/home/xloiseau/bin/unison.solaris-textui, -server)

Received unexpected header from the server: expected
"Unison 2.9.1\n" but received "Unison 2.9.1\013".

This is probably because you have different versions
of Unison installed on the client and server machines.
>>

A lot of messages can be found through Google about
such problems which occured in the past with Cygwin
1.3.11 .

Among the found proposed solutions, I have tried to
set the CYGWIN environment variable to "binmode" or
"nobinmode".

File Synchronizer

I went to your download site and clicked on download latest stable version.  The next page contained list of stuff to download.  Which one is the latest stable version for Win-98????
 
I want to synchronize files between 2 computers, the same way PC anywhere synchronizes files.  Will your program work like this?
 
Thank you.
 
Dave

Re: Unison - can I get all the confirmations to appear in one go.

Hi Andrew,
	You can use unison in batch mode (unison -batch) but have a read of  
the manual about other cool stuff you can do with .prf files.

internal error syncing red hat 8 and 9

I've run into an odd problem: I've just upgraded my laptop from Red Hat
8.0 to Red Hat 9, while my desktop machine remains on Red Hat 8.0 for
the time being. Since doing the upgrade I've had unison fail to
synchronise using configurations that were working fine prior to the
upgrade. Unison scans the directories on both machines before reporting
"Internal error: New archives are not identical", but the contents of
the .unison directory have not been corrupted during the upgrade.

During the upgrade, however, I did backup and restore all the files on
the filesystems, so each file's inode number is likely to have changed.
Is this likely to be causing the problem? Any ideas how I could
workaround the problem? Does it represent a bug in unison?

-Mark.

I'm not precisely sure what is causing the behavior you're seeing, but in
general changing inode numbers out from under Unison is not a good idea --
it does rely on their stability.

The workaround for this (and for other situations where Unison seems
confused) is to delete all of Unison's archive files and synchronize again;
if the two replicas are content-identical, Unison will realize this and
recreate its archives.  (If they are not identical, you may have a little
cleanup to do -- e.g., if it sees a file on one side and not the other, it
will always try to propagate it -- so you will want to run it in interactive
mode and have a look at what files it thinks it wants to transfer.)
