Notable changes since [previous update](https://github.com/bitcoin/bitcoin/pull/30660#pullrequestreview-2779505028) (`git range-diff master 77776c5 ea3cc83`).
* Changed parent test process to run a node, and use it to measure startup-times. That measurement is then used to to cap how long we wait before timing out due to wrong port.
* Forward test framework arguments like `--tmpdir` and `--timeout-factor` to child processes (now with stable hashing).
* Dropped the change to avoid logging node

This looks like it uses JSON-RPC inside Capnproto? Why not just use straight Capnproto?

I was under impression that the only wallet paths that could be loaded are:

https://github.com/bitcoin/bitcoin/blob/06439a14c884d7f81f331646ad361e88b3037a51/src/wallet/wallet.cpp#L2974-L2977

So it would not be possible to load a bare db outside -walletdir. And if the migration code was backing up a bare db file inside -walletdir like `arbitrarywalletname.db` it would just be backed up as `arbitrarywalletname.db_1223.bak`

Yes it is skipping the HTTP part of the protocol but keeping the JSON part. The capnproto interface this exposes looks like:

```
interface Rpc $Proxy.wrap("interfaces::Rpc") {
executeRpc @0 (context :Proxy.Context, request :Text, uri :Text, user :Text) -> (result :Text);
}
```

where `request` and `response` above are JSON text strings with the expected JSON-RPC fields. The schema could be u

I don't think anyone is planning to touch the legacy wallet code anymore, and the migration procedure no longer takes an hour either (which was the reason behind its creation). So I'd say it's no longer relevant as a benchmark.

Good point

This PR currently breaks that. Although `test_direct_file` doesn't currently fail, adding a check for the wallet's name in the backup path does make it fail, e.g.

Hi,

Two suggestions for this doc:

1. "the getBlockHash method of the generated Chain server subclass in bitcoin-wallet" Correction: This should be "in bitcoin-node", not "bitcoin-wallet", since the server class resides in the node process.

2. "capnp files in src/ipc/capnp/ was mostly done" Correction: "were mostly done" (subject-verb agreement: plural noun "files")

Thanks.

Should these be `(height - 1) % LOCKTIME_THRESHOLD` ? Or are we just assuming a hard fork to a new transaction format in the next 9500 years?

Maybe add something like

```python
genblock = create_block(hashprev=int(block["hash"], 16), tmpl=dict(height=block["height"]+1), ntime=block["time"]+1)
genblock.vtx[0].vin[0].nSequence = SEQUENCE_FINAL
genblock.vtx[0].rehash()
genblock.hashMerkleRoot = genblock.calc_merkle_root()
genblock.solve()
self.nodes[0].submitblock(genblock.serialize().hex())

Would it be more elegant to leave the genesis block's nSequence as `MAX_SEQUENCE` to avoid the implication that the genesis block might be timelocked? ie,

```c++
coinbase_tx.vin.resize(1);
coinbase_tx.vin[0].prevout.SetNull();
if (height > 0) {
coinbase_tx.nLockTime = static_cast<uint32_t>(height - 1);
coinbase_tx.vin[0].nSeqeunece = CTxIn::MAX_SEQUENCE_NONFINAL;
}
```

(https://github.com/bitcoin-core/gui/issues/867#issuecomment-2820150044)
To be clear, the actual issue is that cmake has POSITION_INDEPENDENT_CODE, which claims to implement PIC, but it does not. It enables PIE instead, which is not what you actually asked for, and they are unfortunately different enough to matter.

It's quite fine to enforce -fPIC (and also to link with -pie), but cmake simply does not provide the necessary builtin functionality to do it correctly.
