mjolnir.traffic_extract configuration ignored and even rewritten when set to directory which is different from tile dir

[Ashen-Cz]

Reopening from valhalla/valhalla#4380 as @nilsnolde suggested:

Due to some infrastructure issues, I need to keep traffic and tile files separated. So my config looks something like this:

"tile_dir": "/custom_files/valhalla_tiles",
"tile_extract": "/custom_files/valhalla_tiles.tar",
"traffic_extract": "/valhalla/traffic.tar",

Interestingly, upon firing up Valhalla, I've noticed this on log: '(stat): /custom_files/traffic.tar No such file or directory'. I've double checked, modified traffic_extract to /valhalla/traffic.tar again, but it seems that every time I start Valhalla, the "traffic_extract" is rewritten back to /custom_files/traffic.tar . Is this by design and traffic must be in the same dir as tiles or is it bug?

I wouldn’t call it a bug, but it’s also not really necessary.. you can try removing this line:

docker-valhalla/scripts/configure_valhalla.sh

Line 126 in c0389c8

jq --arg d "${TRAFFIC_TAR}" '.mjolnir.traffic_extract = $d' "${CONFIG_FILE}"| sponge "${CONFIG_FILE}"

, should work.
