Hello, I'm currently integrating, refactoring and fixing the original code, in the context of this branch: https://github.com/antirez/redis/commits/geo https://github.com/antirez/redis/commits/geo So far the code was simplified and polished, fixed (it did not returned the right set of elements in all the cases), GEORADIUS speed was improved. On the other side I removed all the JSON things and the Pub/Sub (IMHO is interesting to subscribe to areas to see objects entering/exiting them, not much to position updates since it's the same of doing PUBLISH+GEOADD from the client side). Added: GEOHASH to return a Geohash standard string from of a given element, mainly for interoperability. I'm also adding GEODIST (to calculate distances) and GEOPOS (to retrieve latitude/longitude of objects without the need to query for radius). The work will be available in the context of Redis 3.2, unless I get mad and merge back into 3.0, which is unlikely but not impossible. EDIT: before of three days ago I was not aware of Geohashing at all, so if you have five mins to check the code, I'll be glad :-) Thanks. I'm pretty confident that it's ok now after I added a fuzzy test that replicates the feature (by brute forcing distance computation) in Tcl that checks against the Redis output, but still... EDIT2: wanted to add that I'm very glad Matt efforts are not going to be wasted and we are finally merging this.
