Plamen Todorov	6b82fd94eb	randomize mqtt client id with math/rand Cryptographic randomizer is not required for mqtt clientIds. They should be unique only among currently selected clients.	2019-10-08 20:24:31 +03:00
Plamen Todorov	c3b9a689bb	Use uuid as mqtt clientId Use crypto/random to generate unique mqtt client id. The tile38 prefix makes the connections easily identifiable in the mqtt broker logs.	2019-10-08 09:34:31 +03:00
Plamen Todorov	fb2aef2ce6	MQTT clientId should be unique Each mqtt hook establishes separate connection to the MQTT broker. If their clientIds are all equal the MQTT broker will disconnect the clients - the protocol does not allow 2 connected clients with the same name	2019-10-06 22:15:06 +03:00
tidwall	6257ddba78	Faster point in polygon / GeoJSON updates The big change is that the GeoJSON package has been completely rewritten to fix a few of geometry calculation bugs, increase performance, and to better follow the GeoJSON spec RFC 7946. GeoJSON updates - A LineString now requires at least two points. - All json members, even foreign, now persist with the object. - The bbox member persists too but is no longer used for geometry calculations. This is change in behavior. Previously Tile38 would treat the bbox as the object's physical rectangle. - Corrections to geometry intersects and within calculations. Faster spatial queries - The performance of Point-in-polygon and object intersect operations are greatly improved for complex polygons and line strings. It went from O(n) to roughly O(log n). - The same for all collection types with many children, including FeatureCollection, GeometryCollection, MultiPoint, MultiLineString, and MultiPolygon. Codebase changes - The pkg directory has been renamed to internal - The GeoJSON internal package has been moved to a seperate repo at https://github.com/tidwall/geojson. It's now vendored. Please look out for higher memory usage for datasets using complex shapes. A complex shape is one that has 64 or more points. For these shapes it's expected that there will be increase of least 54 bytes per point.	2018-10-13 04:30:48 -07:00
