[qa] Wait for specific block announcement in p2p-compactblocks
Change check_announcement_of_new_block() to wait specifically for the announcement of the newly created block, instead of waiting for any announcement at all. A difficult to reproduce failure in check_announcement_of_new_block() that happened in a travis build (https://travis-ci.org/bitcoin/bitcoin/jobs/175198367) might have happened because an older announcement was mistaken for the expected one. The error looked like: Assertion failed: Failed File ".../bitcoin/qa/rpc-tests/test_framework/test_framework.py", line 145, in main self.run_test() File ".../bitcoin/build/../qa/rpc-tests/p2p-compactblocks.py", line 787, in run_test self.test_sendcmpct(self.nodes[1], self.segwit_node, 2, old_node=self.old_node) File ".../bitcoin/build/../qa/rpc-tests/p2p-compactblocks.py", line 201, in test_sendcmpct check_announcement_of_new_block(node, test_node, lambda p: p.last_cmpctblock is None and p.last_inv is not None) File ".../bitcoin/build/../qa/rpc-tests/p2p-compactblocks.py", line 194, in check_announcement_of_new_block assert(predicate(peer)) This commit also changes the assertion failed message above to include more detailed information for debug.
