[OSM-dev] osmosis with completeWays option behaves strangely

[ant]

Hi all,

I'm experimenting with osmosis boundig box operations in order to find 
out how completeWays, completeRelations and cascadingRelations behave. 
Comparing the outputs of bbox operations done with completeWays=yes and 
no, respectively, I found something weird. The completeWays output had 
two relations in it that were not there in the default output. I 
understood from the documentation that there should be extra nodes only.

I did:

osmosis --read-xml  file=bremen.osm --bounding-box bottom=53.129883 
left=8.481445 top=53.217773 right=8.569336 completeWays=no --write-xml 
file=nocompleteways
osmosis --read-xml  file=bremen.osm --bounding-box bottom=53.129883 
left=8.481445 top=53.217773 right=8.569336 completeWays=yes --write-xml 
file=completeways

diff nocompleteways completeways

...which gives a long list of nodes plus 2 relations, 20144 and 20614. 
Using osmosis 0.39.
Note also that the bounding box covers an area not fully contained by 
the excerpt.

cheers
