This will crash on master. Fix is currently in the per-txout PR. Edit: Sipa asked me to just add the fix here, doing so now. |
Thanks to Suhas Daftuar for figuring this out.

I can't review the code change in src/txdb.cpp since I don't know that code, but I can confirm that this test causes bitcoind to crash without the code change, and passes successfully with the code change.
A few nits inline. Also consider changing line 35 of the test from:
self.num_nodes = 2to:
self.num_nodes = 1I know that wsan't changed by this PR, but 2 nodes are unnecessary for this test, and changing it to 1 cuts the test time in half (from 5s to 2.5s on my pc) due to node startup/shutdown time.

Can you add a comment (or info log) here explaining what this test is for:
self.log.info("Test that gettxoutsetinfo() works for blockchain with just the genesis block")
test/functional/blockchain.py

Why not test all fields:
assert_equal(res2['bestblock'], node.getblockhash(0)))
assert_equal(len(res2['hash_serialized']), 64)There was a problem hiding this comment.
done (and also added that to the first check)

Again, a comment/info log would be nice here:
self.log.info("Test that gettxoutsetinfo() returns the same result after invalidate/reconsider block")
test/functional/blockchain.py
Outdated

Consider just testing equality of res and res3 for succinctness:
assert_equal(res, res3)There was a problem hiding this comment.
Equality will be the wrong comparison with the disk usage field which is about to be added.
