First discussed in #10357 here: https://github.com/bitcoin/bitcoin/pull/10357#pullrequestreview-59963870 > ... we could simplify this (and possibly other) tests by just adding a way to know if a node is in IBD. I'd like to do that, but I'm not sure it makes sense to complicate this PR with discussion over how that information should be made available. Eg it's not clear to me that the notion of being in IBD is worth exposing to the casual user, versus a hidden rpc call or something, since the definition has changed over time, and may continue to change in the future. But I still do agree that at least for testing purposes it would be far simpler to expose the field somehow... This PR currently implements the simplest way of doing this: adding an `initialblockdownload` field to `getblockchaininfo`. Other approaches we could take: 1. add a new debug RPC method that exposes `IBD` and potentially other information. 2. add a parameter to `getblockchaininfo`, eg `debug_info`, which would cause it to return debug information including IBD 3. add a query string to the url `?debug=true` which would cause RPCs to return additional debug information. I quite like the idea of (3).

Merge #13451: rpc: expose CBlockIndex::nTx in getblock(header) 86edf4a2a502416ba8d6cebbce61030992f7ff6f expose CBlockIndex::nTx in getblock(header) (Gregory Sanders) Pull request description: Recent publication of a weakness in Bitcoin's merkle tree construction demonstrates many SPV applications vulnerable to an expensive to pull off yet still plausible attack: https://bitslog.wordpress.com/2018/06/09/leaf-node-weakness-in-bitcoin-merkle-tree-design/ Including the coinbase in the txoutproof seems the most effective fix, however results in a significant efficiency downgrade. Transactors will not even know a priori what the size of their proof will be within a couple orders of magnitude, unless they use the mid-state of SHA2 as detailed in the blog post. Some applications, like Elements blockchain platform that take SPV-style proofs have optional access to a bitcoind to verify these proofs of inclusion and check depth in the chain. Returning `CBlockIndex::nTx` would allow an extremely easy and compact way of checking the depth of the tree, with no additional overhead to the codebase, and works with pruned nodes. `getblockheader` is arguably not the place for it, but as mentioned before, is a natural workflow for us checking depth of a block in a possibly pruned node. We should also ensure that `verifytxoutproof` ends up validating this depth fact as well, but left this for another PR.

Merge #10711: [tests] Introduce TestNode 789733891 [tests] Introduce TestNode (John Newbery) Pull request description: Continues #10082 TestNode is a class responsible for all state related to a bitcoind node under test. It stores local state, is responsible for tracking the bitcoind process and delegates unrecognised messages to the RPC connection. This commit changes start_nodes and stop_nodes to start and stop the bitcoind nodes in parallel, making test setup and teardown much faster. On my vm, this changeset reduces total test_runner runtime for the base set of tests (including building the cache) from 263s to 195s (a 25% speedup). Note that the time reported by test_runner does not include time spent building the cache: *with TestNode*: ``` → date +"%T" ; ./test_runner.py -q ; date +"%T" 12:48:04 ..................................................................................................................................................................................................................................................................................................................................
