From a9ef702a877a964bac724a56e2c0b5bee4ea7586 Mon Sep 17 00:00:00 2001 From: Ryan Ofsky Date: Wed, 4 Oct 2023 10:58:47 -0400 Subject: assumeutxo: change getchainstates RPC to return a list of chainstates Current getchainstates RPC returns "normal" and "snapshot" fields which are not ideal because it requires new "normal" and "snapshot" terms to be defined, and the definitions are not really consistent with internal code. (In the RPC interface, the "snapshot" chainstate becomes the "normal" chainstate after it is validated, while in internal code there is no "normal chainstate" and the "snapshot chainstate" is still called that temporarily after it is validated). The current getchainstatees RPC is also awkward to use if you to want information about the most-work chainstate because you have to look at the "snapshot" field if it exists, and otherwise fall back to the "normal" field. Fix these issues by having getchainstates just return a flat list of chainstates ordered by work, and adding new chainstate "validated" field alongside the existing "snapshot_blockhash" so it is explicit if a chainstate was originally loaded from a snapshot, and whether the snapshot has been validated. --- test/functional/feature_assumeutxo.py | 47 ++++++++++++++++------------------- 1 file changed, 22 insertions(+), 25 deletions(-) (limited to 'test/functional') diff --git a/test/functional/feature_assumeutxo.py b/test/functional/feature_assumeutxo.py index be0715df32..15cacc204c 100755 --- a/test/functional/feature_assumeutxo.py +++ b/test/functional/feature_assumeutxo.py @@ -128,10 +128,13 @@ class AssumeutxoTest(BitcoinTestFramework): assert_equal(loaded['coins_loaded'], SNAPSHOT_BASE_HEIGHT) assert_equal(loaded['base_height'], SNAPSHOT_BASE_HEIGHT) - monitor = n1.getchainstates() - assert_equal(monitor['normal']['blocks'], START_HEIGHT) - assert_equal(monitor['snapshot']['blocks'], SNAPSHOT_BASE_HEIGHT) - assert_equal(monitor['snapshot']['snapshot_blockhash'], dump_output['base_hash']) + normal, snapshot = n1.getchainstates()["chainstates"] + assert_equal(normal['blocks'], START_HEIGHT) + assert_equal(normal.get('snapshot_blockhash'), None) + assert_equal(normal['validated'], True) + assert_equal(snapshot['blocks'], SNAPSHOT_BASE_HEIGHT) + assert_equal(snapshot['snapshot_blockhash'], dump_output['base_hash']) + assert_equal(snapshot['validated'], False) assert_equal(n1.getblockchaininfo()["blocks"], SNAPSHOT_BASE_HEIGHT) @@ -159,20 +162,11 @@ class AssumeutxoTest(BitcoinTestFramework): self.connect_nodes(0, 1) self.log.info(f"Ensuring snapshot chain syncs to tip.
