Convert forking osm-p2p documents into a linear history.
Transforms a list of osm-p2p-db documents into a sublist with a linear (non-forking) history.
var defork = require('osm-p2p-defork')
osm.query([[-90, 90], [-180, 180]], function (err, docs) {
docs = defork(docs)
console.log(docs)
})outputs the results from the osm.query(), but with a linear history (no forked
documents).
var defork = require('osm-p2p-defork')Consumes a list of OSM documents, formatted as would be returned by
osm-p2p-db's query
function.
Returns the same documents, but with certain documents filtered to present a linear history.
Timestamps (a timestamp field) should be present on all documents. If they
aren't, sorting happens based on the document's version field. This guarantees
a non-forking history, but it will not likely be semantically what you want.
With npm installed, run
$ npm install osm-p2p-defork
