Upload of a single way gives changeset with lots of other existing ways

[Ldp]

I downloaded an area in a new layer and added a single building (copy/pasted it from another layer). Then I uploaded, but the changeset now contained that building, and *lots* of other ways that I had downloaded. No existing nodes were uploaded, just lots of ways.

The way I added:
​http://www.openstreetmap.org/browse/way/44098703

The changeset JOSM created:
​http://www.openstreetmap.org/browse/changeset/3082764

JOSM 2427

I tried to reproduce:

• downloaded an area in layer 1
• created new layer 2
• createed a building in layer 2
• copy building from layer 2 in layer 1
• upload layer 1

==> everything is fine.

Anything else which is special in your case? Did you really upload the layer which only included one new building? What did the upload dialog show? Just a couple of nodes and one way to upload?

Tried again with 2431 & 2436, with and without plugins and also doing ant clean ; ant dist.

• Open JOSM.
• Drop a .osm on it with things to import. Every element is still unknown to OSM (negative id)
• Zoom in to near building to import.
• File -> New, File -> Download from OSM
• Activate first layer, select building, Copy, select OSM layer, Paste
• Press upload

The upload dialog says that it wants to add 9 nodes and a way. That's fine, that's my new building. It also says it wants to *modify* 76 other objects. Objects which happen to be in the same area I downloaded from OSM, but which I definately didn't touch.

The thing you did differently is to create both layers in the same session. That works for me too. Try creating an object and save it as .osm. Doesn't have to be a building. I also triggered this bug with an untagged 4-node area. Then restart, open JOSM, open/drag the .osm on JOSM, etc. Same as I did.

Test file, as mentioned in the previous comment

Same happend to me. Command stack lists 30 changes, Upload tried to edit 5000 additional ways.

Resulting changeset after cancelling upload: ​http://www.openstreetmap.org/browse/changeset/3086373

• JOSM 2417 (from Website), many plugins (updated today)
• only one layer
• ​First Upload was OK

Saving results in a .osm file with > 5000 ways marked with action='modify' (in addition to the 5 relations and 6 points I actually changed.

Steps:

• Downloaded map data
• Edited
• Uploaded (OK)
• Downloaded more map data
• Edited
• Uploading broken

Already fixed in r2431 after #3804?

[Ldp]

No, as I said above: I tried 2431 and 2436.

The #3804 cases also sound distinctly different.

[stoecker]

Dounds like the data merge function sets "modified" flag also for downloaded data.

Ticket #3905 has been marked as a duplicate of this ticket.

[Gubaer]

Should be fixed in r2443.

First tests (with 2447) look good. I cannot reproduce what I described above.
