84bc35d7a5 test: feature_rbf.py: check specified wallet type availability (Sebastian Falbesoner)
Pull request description:
The test currently leads to a failure if in general wallet support is compiled, but the library for the specified type (BDB/SQLite) is not, i.e. if started with the `--legacy-wallet` parameter, but bitcoind is compiled without BDB support, see e.g. https://github.com/bitcoin/bitcoin/pull/23682#issuecomment-989044207
Fix this by checking if the specified wallet type (BDB for legacy wallet, SQLite for descriptor wallet) is available.
Also move the helper `is_specified_wallet_compiled()` to the
test framework's class BitcoinTestFramework first, so it can be reused.
Should further pave the way for #23682. On my local instance without BDB compiled, all targets in test_runner pass now.

The test currently leads to a failure if in general wallet
support is compiled, but the library for the specified type
(BDB/SQLite) is not, i.e. if started with the
`--legacy-wallet` parameter, but bitcoind is compiled
without BDB support.

Also move the helper `is_specified_wallet_compiled()` to the

Currently the test performs the wallet-relevant parts if
_any_ wallet type support is compiled in, independently of
whether the test is run with legacy or descriptor wallet
specified. This leads to a failure if the test is started
with the `--legacy-wallet` parameter, but bitcoind is
compiled without BDB support.
Fix this by checking if the specified wallet type (BDB for

dce8c4c381 rpc: getblockfrompeer (Sjors Provoost)
b884ababc2 rpc: move Ensure* helpers to server_util.h (Sjors Provoost)
Pull request description:
This adds an RPC method to fetch a block directly from a peer. This can used to fetch stale blocks with lower proof of work that are normally ignored by the node (`headers-only` in `getchaintips`).
Usage:
```
bitcoin-cli getblockfrompeer HASH peer_n
```
Closes#20155
Limitations:
* you have to specify which peer to fetch the block from
* the node must already have the header

1dcba996d3 Coinbase receivedby rpcs release notes (Andrew Toth)
b5696750a9 Test including coinbase transactions in receivedby wallet rpcs (Andrew Toth)
bce20c34d6 Include coinbase transactions in receivedby wallet rpcs (Andrew Toth)
Pull request description:
The current `*receivedby*` RPCs filter out coinbase transactions. This doesn't seem correct since an output to your address in a coinbase transaction *is* receiving those coins.
This PR corrects this behaviour. Also, a new option `include_immature_coinbase` is added (default=`false`) that includes immature coinbase transactions when set to true.
However, since this is potentially a breaking change this PR introduces a hidden configuration option `-deprecatedrpc=exclude_coinbase`. This can be set to revert to previous behaviour. If no reports of broken workflow are received, then this option can be removed in a future release.
Fixes https://github.com/bitcoin/bitcoin/issues/14654.

35d928c632 rpc: deprecate fee fields from mempool entries (josibake)
Pull request description:
per #22682 , top level fee fields for mempool entries have been deprecated since 0.17 but are still returned. this PR properly deprecates them so that they are no longer returned unless `-deprecatedrpc=fees` is passed.
the first commit takes care of deprecation and also updates `test/functional/mempool_packages.py` to only use the `fees` object. the second commit adds a new functional test for `-deprecatedrpc=fees`
closes#22682
## questions for the reviewer
* `-deprecatedrpc=fees` made the most sense to me, but happy to change if there is a name that makes more sense
* #22682 seems to indicate that after some period of time, the fields will be removed all together. if we have a rough idea of when this will be, i can add a `TODO: fully remove in vXX` comment to `entryToJSON`
## testing
to get started on testing, compile, run the tests, and start your node with the deprecated rpcs flag:
```bash
./src/bitcoind -daemon -deprecatedrpc=fees
```
you should see entries with the deprecated fields like so:
```json
{
"<txid>": {
"fees": {
"base": 0.00000671,
"modified": 0.00000671,
"ancestor": 0.00000671,
"descendant": 0.00000671
},
"fee": 0.00000671,
"modifiedfee": 0.00000671,
"descendantfees": 671,
"ancestorfees": 671,
"vsize": 144,
"weight": 573,
...
},
```
you can also check `getmempoolentry` using any of the txid's from the output above.
next start the node without the deprecated flag, repeat the commands from above and verify that the deprecated fields are no longer present at the top level, but present in the "fees" object

Pull request description:
The functional test wallet_transactiontime_rescan.py currently fails on master branch, if descriptor wallets are used (argument `--descriptors`). This is due to the fact that in this case, the test framework maps the importaddress RPC calls to the importdescriptors RPC (rescan=False -> timestamp='now'), which always rescans blocks of the past 2 hours, based on the current MTP timestamp. In order to avoid importing the last address (wo3), we generate 10 more blocks with advanced time, to ensure that the balance after importing is zero:

Calling this test with descriptor wallets is also added to test runner. Fixes#23562.

Pull request description:
This PR fixes certain use-cases when **send-to-self** transactions are missing from `listtransactions` output.
1. When a receiving address is generated externally to the wallet
(e.g. same wallet running on two nodes, or by 3rd party from xpub)
2. When restoring backup with lost metadata, but keypool gap is not exceeded yet
When the block is connected or tx added to mempool we already mark used keys. This PR extends this logic to determine whether the destination is a receiving one and if yes add it to the address book with empty label.
Works both for legacy and descriptors wallets.
- For legacy it uses the internal flag from the keypool entry. Caveat: because we don't know which script type would be used we add all possible destinations for such keys.
- For descriptor wallets it uses internal flag for the script pub key manager. Caveat: it only works for active descriptors.

Pull request description:
It seems confusing to call `GetAdjustedTime` there, because no offset could have been retrieved from the network at this point. Even if connman was started, `timedata` needs at least 5 peer connections to calculate an offset.
Fix the confusion by replacing `GetAdjustedTime` with `GetTime`, which does not change behavior.
Also:
* Replace magic number with `MAX_FUTURE_BLOCK_TIME` to clarify the context
* Add test, which passes both on current master and this pull request

Remove 2 circular dependencies: validation - txmempool and validation - policy/rbf - txmempool
Validation should depend on txmempool (e.g. `CChainstateManager` has a mempool and we often need to know what's in our mempool to validate transactions), but txmempool is a data structure that shouldn't really need to know about chain state.
- Changes `removeForReorg()` to be parameterized by a callable that returns true/false (i.e. whether the transaction should be removed due to being now immature or nonfinal) instead of a `CChainState`. The mempool really shouldn't need to know about coinbase maturity or lockpoints, it just needs to know which entries to remove.

d9803f7a0a test: add stress tests for initialization (James O'Beirne)
23f85616a8 test: add node.chain_path and node.debug_log_path (James O'Beirne)
Pull request description:
In the course of coming up with a test plan for #23280, I thought it would be neat to include a Python snippet showing how I tested the initialization process. I quickly realized I was reinventing the functional test framework... so here's a new test.
This change bangs init around like the Fonz hitting a jukebox. It adds some interesting (read: lazy and random) coverage for the initialization process by
- interrupting init with SIGTERM after certain log statements,
- interrupting init at random points, and
- starting init with some essential data missing (block files, block indices, etc.) to test init error paths.
As far as I can tell, some of these code paths are uncovered otherwise (namely the startup errors).
---
Incidentally, I think I may have uncovered some kind of a bug or race condition with indexing initialization based on an intermittent failure in this testcase. This test sometimes fails after shutting down immediately after `loadblk` thread start:
```

and then fails to start up afterwards. Combined logs showing `Error: txindex best block of the index goes beyond pruned data`, when the node under test is not pruned:

6aed8b7e9b [test] tx processing before and after ibd (glozow)
b9e105b664 [net_processing] ignore all transactions during ibd (glozow)
Pull request description:
This is basically a mini, IBD-only version of #21224
Incoming transactions aren't really relevant until we're caught up. That's why we send a giant feefilter and don't send tx getdatas, but we also shouldn't process them if peers send them anyway. Simply ignore them.

- Actually generate an assumeutxo hash and display it
- Add nchaintx to output (necessary for use in chainparams entry)
- Add path of serialized UTXO file to output
No behavior change.
Parameterize removeForReorg using a CChain and callable that
encapsulates validation logic. The mempool shouldn't need to know a
bunch of details about coinbase maturity and lock finality. Instead,
just pass in a callable function that says true/false. Breaks circular
dependency by removing txmempool's dependency on validation.
a99ed89865 psbt: sign without finalizing (Andrew Chow)
Pull request description:
It can be useful to sign an input with `walletprocesspsbt` but not finalize that input if it is complete. This PR adds another option to `walletprocesspsbt` to be able to do that. We will still finalize by default.
This does not materially change the PSBT workflow since `finalizepsbt` needs to be called in order to extract the tx for broadcast.

988024fe37 test: add check_node_connections in util (brunoerg)
Pull request description:
This function (`check_node_connections`) exists in `feature_anchors.py` and `p2p_add_connections.py` and does the same thing in both, this PR moves this function to util to avoid repetition and facilitate maintenance.

fa4e09924b refactor: Replace validation.h include with forward-decl in miner.h (MarcoFalke)

fa53e3a58c scripted-diff: Move miner to src/node (MarcoFalke)
Pull request description:
It is impossible to run the miner without a node (validation, chainstate, mempool, rpc, ...). Also, the module is in the node library. Thus, it should be moved to `src/node`.
Also, replace the `validation.h` include in the header with a forward-declaration.
