From f19abd90537fe71e757fdbfc52cd2288e967bb6e Mon Sep 17 00:00:00 2001 From: Suhas Daftuar Date: Fri, 31 Mar 2017 13:24:35 -0400 Subject: [PATCH] [qa] Fixes segwit block relay test after inv-direct-fetch was disabled This test was passing because we never fetch blocks if we only receive an inv and not the header (after 037159cebf1eae4445050cec029986514ed4e9e2), and this test wasn't delivering the header. --- test/functional/p2p-segwit.py | 17 ++++++----------- 1 file changed, 6 insertions(+), 11 deletions(-) diff --git a/test/functional/p2p-segwit.py b/test/functional/p2p-segwit.py index 335777b2a..93d42b3df 100755 --- a/test/functional/p2p-segwit.py +++ b/test/functional/p2p-segwit.py @@ -61,16 +61,6 @@ class TestNode(NodeConnCB): self.send_message(msg) self.wait_for_getdata() - def announce_block(self, block, use_header): - with mininode_lock: - self.last_message.pop("getdata", None) - if use_header: - msg = msg_headers() - msg.headers = [ CBlockHeader(block) ] - self.send_message(msg) - else: - self.send_message(msg_inv(inv=[CInv(2, block.sha256)])) - def request_block(self, blockhash, inv_type, timeout=60): with mininode_lock: self.last_message.pop("block", None) @@ -1029,13 +1019,18 @@ class SegWitTest(BitcoinTestFramework): block4 = self.build_next_block(nVersion=4) block4.solve() self.old_node.getdataset = set() + # Blocks can be requested via direct-fetch (immediately upon processing the announcement) # or via parallel download (with an indeterminate delay from processing the announcement) # so to test that a block is NOT requested, we could guess a time period to sleep for, # and then check.
