Hello Michael, hello *,
after having installed Core Update 153 Development Build: next/e8ecc81a on my testing machine and rebooting, I am glad to finally confirm the libloc version included into it producing the correct and desired output for xt_geoip within a reasonable amount of time:
[root@maverick ~]# time location export --directory=tmp --format=xt_geoip
real 0m48.298s user 0m46.938s sys 0m0.301s
CPU is an Intel N3150, the system was under constant albeit medium load while executing this.
The generated IPv4 networks for DE look fine as they contain no apparent overlapping entries, while all of them are ordered ascending. After reloading the updating procedure by running
bash -x /usr/local/bin/update-location-database
pinging ping.ipfire.org (which is allowed by an outgoing firewall rule for destination country DE) works again. Yay.
To conclude, libloc now finally seems to be ready for production and the more accurate database version (which we have to generate and bake into Core Update 153, yet) - at least from my point of view.
Thanks, and best regards, Peter Müller
