fadf6bd04f002d05aaff8eba74015e25a41966bc refactor: Remove unused request.fHelp (MarcoFalke) fad889cbf0b6c46da2e110b73cbea55e4ff7951e wallet: Make RPC help compile-time static (MarcoFalke) Pull request description: Currently calling `help` on a wallet RPC method will either return `help: unknown command: getnewaddress` or the actual help. This runtime dependency of the help is a bug that complicates any tool that relies on documentation. Also, the code that enables the bug is overly complicated and confusing. The fix is split into two commits: * First, a commit that can be reviewed with the `--color-moved=dimmed-zebra` option and tested with the included test. * Second, a commit that removes the complicated and confusing code.

Tests p2p message `msg_mempool`: a node that has `peerbloomfilters` enabled should send its mempool (disabled behavior already tested [here](https://github.com/bitcoin/bitcoin/blob/master/test/functional/p2p_mempool.py)). 2. Tests that bloomfilter peers with [`fRelay=False`](https://github.com/bitcoin/bips/blob/master/bip-0037.mediawiki#extensions-to-existing-messages) in the `version` message should not receive any invs until they set the filter. The rest is the same as whatโ€™s already tested in `p2p_filter.py`. 3. Tests that peers get disconnected if they send `filterload` or `filteradd` p2p messages to a node with bloom filters disabled. 4. Refactor: renames p2p_mempool.py to p2p_nobloomfilter_messages.py. 5.

You could manually parse the raw `"hex"` fields for transactions if you really wanted to, but this seems to defeat the point of having a JSONification of the raw block/transaction data. Without the nonce you can't: 1. calculate and validate the witness commitment yourself, you can generate the witness tx merkle root but you don't have the nonce to combine it with 2. reconstruct the raw block form because you don't have `scriptWitness` stack associated with the coinbase (although you know how big it will be and can guess the common case of `[0x000...000]`) I'm building some archiving tooling for block data and being able to do a validated two-way conversion is very helpful. ## What This PR simply makes the `txinwitness` field not dependent on whether we are working with the coinbase or not. So you get it for the coinbase as well as the rest. ## Examples Common case of a `[0x000...000]` nonce: 00000000000000000000140a7289f3aada855dfd23b0bb13bb5502b0ca60cdd7 ```json "vin": [ { "coinbase": "0368890904c1fe8d5e2f706f6f6c696e2e636f6d2ffabe6d6d5565843a681160cf7b08b1b74ac90a719e6d6ab28c16d336b924f0dc2fcabdc6010000000000000051bf2ad74af345dbe642154b2658931612a70d195e007add0100ffffffff", "txinwitness": [ "0000000000000000000000000000000000000000000000000000000000000000" ], "sequence": 4294967295 } ], ... ``` Novel nonce value: 000000000000000000008c31945b2012258366cc600a3e9a3ee0598e8f797731 ```json "vin": [ { "coinbase": "031862082cfabe6d6d80c099b5e21f4c186d54eb292e17026932e52b1b807fa1380574c5adc1c843450200000000000000", "txinwitness": [ "5b5032506f6f6c5d5b5032506f6f6c5d5b5032506f6f6c5d5b5032506f6f6c5d" ], "sequence": 4294967295 } ], ... ``` ## Alternatives This field could be renamed for the coinbase, `"witnessnonce"` perhaps. It could also be omitted when null/zero (`0x000...000`). ## Tests This didn't break any tests and I couldn't find an obvious way to include a test for this. If this is desired I'd apreicate some pointers.
