[Owncloud] ownCloud Client 1.1.0 beta1

[Emre Erenoglu]

Hi Klaas,

I will test it tonight. But do you have any document that I can read to
understand how the sync process works?

Scenario 1: Team working on a document
1) files uploaded from client1 to server  (thus server assigns an ID to it,
is client aware of this ID?)
2) client2 syncs the file to his computer (is client2 aware of this ID)
3) client2 user updates the file
4) client2 understands in next scheduled sync that file is updated (new
timestamp in local?)  locally
5) client2 updates the server, server issues a new ID
Now, how does client1 understand that the file is updated on the server and
that he shall overwrite local version? (by comparing his ID & the ID he got
from server?)

Scenario 2: A conflict (same as above mostly, but client1 also updates in
the meantime)
1) files uploaded from client1 to server  (thus server assigns an ID to it,
is client aware of this ID?)
2) client2 syncs the file to his computer (is client2 aware of this ID)
3) client2 user updates the file
4) client2 understands in next scheduled sync that file is updated (new
timestamp in local?)
5) client2 updates the server, server issues a new ID
6) In the meantime, client1 user also updated the file
7) client1 tries to update file on server, sees a different ID than he
expected (conflict)
Now, how does client1 resolve the conflict?
A) Does not resolve, create two files
B) Does not resolve, raise a warning message box to user and ask him to
choose which version is right
C) Checks the timestamps on the server & client, overwrites the old one
(but then again server & client needs to have correct time!)

Above is a hypothetical workflow, the way the client & server works might
be totally different. I'm looking forward for your comments,

Best regards,
Emre
