Client version: 0.2.100
Server version: 7c3a066d74d3
OS: Reproduced on Linux x86 and Vista 32bit 

After updating both my server and client, deleting all server side data, and initiating a first sync from a client, the process errors very early on throwing an error from the client engine, summarised here:

21:44	Engine.Clients	INFO	Applied 0 records, reconciled 0 records
2009-02-14 18:21:44	Engine.Clients	DEBUG	Preparing 2 outgoing records
2009-02-14 18:21:44	Engine.Clients	WARN	Sync failed

Thanks.  That clients file is broken indeed!

Comment 4

[Darren Worrall]

Thanks Dan :) Out of curiosity, could you explain how it's broken?

Should I delete the clients file(s) so I can get up and running again, or would you like me to leave it in place to test any fixes?

Here's the clients file after running it through jsonlint.org (to format it):

{
    "c3d88f13-337e-414b-a152-a5cb9cb60816": true,
    "1abfac95-96d1-40f4-8d54-8bcb2b835c2a": {
        "name": "Firefox",
        "type": "desktop"
    }
}

Each GUID corresponds to a client.  Notice how one just says 'true'?  That's wrong.

You could try deleting the file and clearing the clients .lastSync pref

Thanks for the explanation :)

Deleted the file on one machine, restarted Firefox and it's sync'ing again. Will get to my other clients over the next day or so and bring them all back online, will see if it trips up again. 

It must have happened at some point during the upgrade of the client and/or server, so the conditions have changed.

Let me know if you see it again.  I think it's leftover from a previous version of the clients engine.

I'm adding code that will clean it up on upgrade.
