Just forget this! I've made a mistake applying the patch...

Now the patch is COMPLETELY added to the TAH client.
First result is that the download takes much longer than without the
patch since three XAPI calls are made. For the tile I've tested it took
603 seconds instead of 7 seconds. Then the resulting file size was much
bigger (41 MB instead of 7MB) and thus the client took much longer to
render the tile (1531 instead of 623 seconds) (does this include the
download time?). BUT the result is OK!! So, it is a interesting step in
the way to solve this issue.

I've tested with this tile:
http://tah.openstreetmap.org/Browse/details/tile/12/1106/1610/

Biggest disadvantage is that XAPI necessarily NEEDS TO BE up all the
time which is not always the case.

And the resulting data.osm file is not loadable in JOSM since there are
versions in the first part (from XAPI) but versions are missing in the
second part (from TRAPI).



I'm just thinking on a more complex but less server stressing solution
which would also solve some other problems (e.g. the very long way
problem). I will post it here soon... but someone else will have to
implement it since it requires changes to the client (and I'm not a
PEARL programmer) and an small additional server.


Cheers
Andre
