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.

Strictly speaking, this is a bug fix, because with the release of 0.16, we create segwit transactions in our wallet by default without checking if they are allowed by local policy. More broadly, this simplifies the code as if "premature witness" was always set to true with the corresponding command line args.

(Motivated by my opinion that the dev tools are mostly for generating code and updating the repo whereas the linters are read-only checks.) Also, adds a readme to clarify that checks and linters are only meant to prevent bugs and user facing issues, not merely stylistic preference or inconsistencies. (This is motivated by the diversity in developers and work flows as well as existing code styles. It would be too disruptive to change all existing code to a single style or too burdensome to force all developers to adhere to a single style. Also note that our style guide is changing, so locking in at the wrong style "too early" would only waste resources.)

This functionality has been requested for various reasons: - security (DoS): reject messages can reveal internal state that can be used to target certain resources such as the mempool more easily. - bandwidth: a typical node sends lots of reject messages; this counts against upstream bandwidth. Also the reject messages tend to be larger than the message that was rejected. On the other hand, reject messages can be useful while developing client software (I found them indispensable while creating bitcoin-submittx), as well as for our own test cases, so whatever the default becomes on the long run, IMO the functionality should be retained as option.

09c6699900 [qa] Handle disconnect_node race (Suhas Daftuar) Pull request description: Several tests call disconnect_nodes() on each node-pair in rapid succession, resulting in a race condition if a node disconnects a peer in-between the calculation of the nodeid's to disconnect and the invocation of the disconnectnode rpc call. Handle this. Tree-SHA512: 3078cea0006fcb507c812004a777c505eb1e9dda7c6df12dbbe72395a73ff6f6760f597b6492054f5487b34534417ddef5fbad30553c135c288c4b7cfce79223

2018-05-09[tests] Remove spurious error log in p2p_segwit.pyJohn Newbery
Since 265d7c44b1aae06aee93f745a865807732218a73, when wait_until() fails, an error message is logged to the test framework log. This means that if wait_until() is called inside a try-except with the expectation that it will fail, a spurious error message is logged. wait_until() shouldn't be called with the expectation of failure. Fix that in p2p_segwit.py.
