From 50262d89531692473ff557c1061aee22aa4cca1c Mon Sep 17 00:00:00 2001 From: Suhas Daftuar Date: Tue, 18 Nov 2014 22:16:32 +0100 Subject: Allow block announcements with headers This replaces using inv messages to announce new blocks, when a peer requests (via the new "sendheaders" message) that blocks be announced with headers instead of inv's. Since headers-first was introduced, peers send getheaders messages in response to an inv, which requires generating a block locator that is large compared to the size of the header being requested, and requires an extra round-trip before a reorg can be relayed. Save time by tracking headers that a peer is likely to know about, and send a headers chain that would connect to a peer's known headers, unless the chain would be too big, in which case we revert to sending an inv instead. Based off of @sipa's commit to announce all blocks in a reorg via inv, which has been squashed into this commit.
