commit f337c14e52f8290a0ce993339cca757cf5249153 Author: Karsten Loesing karsten.loesing@gmx.net Date: Fri Sep 20 17:27:52 2013 +0200

Merge two writer classes to speed up rDNS lookups.

The NodeDataWriter and DetailsDataWriter did very similar things. They processed various descriptors and performed GeoIP and rDNS lookups to learn the latest status of a relay or bridge for summary and details documents. Merging these classes makes sense, because we can start rDNS lookups much earlier which then run in the background. --- src/org/torproject/onionoo/DetailsDataWriter.java | 683 --------------------- src/org/torproject/onionoo/Main.java | 32 +- src/org/torproject/onionoo/NodeDataWriter.java | 649 +++++++++++++++++++- 3 files changed, 655 insertions(+), 709 deletions(-)
