b55f9e9e6a Do not route through channels for which we did not receive 
both updates, because this often means one of the nodes is
offline.

f2d58d0e3f optimize channel_db: 
- use python objects mirrored by sql database
 - write sql to file asynchronously
 - the sql decorator is awaited in sweepstore, not in channel_db

62f58c18fe ChannelDB.on_node_announcement: some speed-up 
(e.g. for 100 node anns, was ~5 seconds, now 0.7 sec; so still slow)

93e8d4f953 channel_db: fix timestamp_range, reduce verbosity 2019-08-20 09:03:11 +02:00
ThomasV
aa398993cf lnrouter fixes: 
- use gossip_queries_req instead of initial_routing_sync
 - add connected nodes to recent peers only after successful init
 - derive timestamp used with gossip_timestamp_filter from channel_db
 - fix query_short_channel_ids:
     1. channel IDs must be sorted with zlib
     2. limit request to 100
     3. do not abuse this to request node_announcements; it is fine not to have all nodes.
 - fix get_recent_peers:
     1. do not set last_connected_date to 'now' if we never connected a node
     2. sql query was misconstructed and was returning only one peer
 - populate FALLBACK_NODE_LIST_MAINNET with nodes that have the requested flags
