Are syncadaptors supposed to sync deletions back from the server?

[Danielo Rodríguez]

Hello Everyone,

Playing with the couchdb adaptor some users have realized that there are problems with Draft tiddlers. Basically there are problems with deletions, and the draft tiddlers are the biggest problem related to this. Is supposed that the sync module should take care of this? I mean, will it ask for the syncadaptor deletions?

Regards

Hi Danielo

Deletions are not currently handled properly by the sync mechanism. A deletion from the browser will be synced to the server, but won't get propagated onwards to other users connected to the same server. The sync logic will need extending to make things work properly: essentially, the syncer module should assume that any tiddlers that are not returned by getSkinnyTiddlers() have been deleted on the server, and need deleting locally.

Best wishes

Jeremy.

Hello Jeremy

The sync logic will need extending to make things work properly: essentially, the syncer module should assume that any tiddlers that are not returned by getSkinnyTiddlers() have been deleted on the server, and need deleting locally.

That is a too destructive approach. What about those tiddlers that are not stored on the server but locally? What if TW is capable to talk to several servers/databases ? How does tiddlyspace handle this?
