Re: [multisync-users] Re: Re: [Multisync-users] Palm plugin

I am not too familiar with how Multisync handles things, but I did try 
one thing which sort-of did what I wanted.  What I did was to force the 
Palm plugin to always assume every record changed when doing a sync.  
That seemed to do most of the things I wanted when paired with the 
Evolution plugin.  But, a backup plugin sync of Evolution plugin, I 
noticed that the modification time of every record was being changed 
every time I synced the Palm device to Evolution.  That didn't seem 
exactly right to me.

Basically the lastSyncPC is supposed to be some sort of unique ID for 
each PC that you want to sync with.  Then, the sync software can check 
to see if it is the same as what it expects.  If it is different, then a 
"slow sync" would need to be performed to make sure that all changes are 
accounted for.

   

Sounds logical :)

 

Jpilot handles this, and I looked at the code a tiny bit yesterday.  I 
am not sure how the unique code is generated, since I didn't look at 
that part of the code, but it has a seemingly random number for that.

The big problem is that trying to figure out what changed on the Palm 
device gets very tricky when you can't rely on the modification flags 
for the records.  That is easy to see in the Jpilot code, which gets 
very complicated when the lastSyncPC ID doesn't match and it goes into 
"slow sync" mode.  I am not really sure how to solve it easily.
   

We already have this part implemented... (It is called "resync" in
multisync. So it should be pretty fast to write this. I will take care
of this (and some other stuff with the palm plugin) soon (e.g. when i
find some time :)
 

A full solution would probably have to involve making a Palm plugin copy 
of all the records so that they can be compared to the Palm device ones 
if needed.  Once the changes are determined there, they would be synced 
to the other Multisync plugin.  I guess that is a lot more code...

Or, I suppose I could try to just sync to one system... 

Even if the "full sync" mode isn't added to the Multisync plugin, it 
would probably be a good idea to warn the user that syncing with 
multiple desktop applications may result in strange behavior.
