"""Test whether we backfill data from the blockchain correctly.
For normal operation we will process any block after the initial start
height, or rescan height, but for gossip we actually also need to backfill
the blocks we skipped initially. We do so on-demand, whenever we see a
channel_announcement referencing a blockheight we haven't processed yet,
we fetch the entire block, extract P2WSH outputs and ask `bitcoin
gettxout` for each of them. We then store the block header in the `blocks`
table and the unspent outputs in the `utxoset` table.
The test consist of two nodes opening a channel at height X, and an
unrelated P2WSH transaction being sent at the same height (will be used to
check for completeness of the backfill). Then a second node starts at
height X+100 and connect to one of the nodes. It should not have the block
in its DB before connecting. After connecting it should sync the gossip,
triggering a backfill of block X, and all associated P2WSH outputs.
