Resuming chunks upload creates duplicates ?

[pieren]

Hi josm-team,

French users like the chunk uploads feature to import buildings from the cadastre. But it seems that if a chunk failes, a resuming will create duplicates in the database. By a quick look on the source, it seems that JOSM is updating its local ID's only when all chunks have succeeded. So if the 4th chunk upload failes, the first 3 chunks will be duplicated in the database at the next upload although they went well the first time (if I read correctly OsmServerWriter.uploadChangesInChunks()). Would it be possible to avoid such duplicates when resuming a chunks upload ?

Last time i checked, this was ok. Can you try on dev-server and confirm that it is really broken?

I simulated an exception and the succesfull chunks are correctly handled. So the duplicated data with bigger imports in the server are coming from somewhere else.

A few weeks ago a bug like you describe was closed. So it may be from that time.
