Pull request description:

  These helpers are exclusively used in txmempool.cpp, hence they should also be moved there. The PR also contains a commit which fixes const-correctness for parents in `CTxMemPool::UpdateAncestorsOf` and declares them as reference to avoid a copy.

Merge bitcoin/bitcoin#23223: Disable lock contention logging in checkqueue_tests
6ae9f1cf9604227e9dfda1f6c91fc711d154362e Disable lock contention logging in checkqueue_tests (Jon Atack)

Pull request description:

  This patch disables lock contention logging in the checkqueue_tests as some of these tests are designed to be heavily contested to trigger race conditions or other issues. This created very large log files when run with DEBUG_LOCKCONTENTION defined (up to v22) or with lock logging enabled by default in current master.

  Examples running the following command:

  ```
  $ ./src/test/test_bitcoin -t checkqueue_tests/test_CheckQueue_Correct_Random -- DEBUG_LOG_OUT > testlog.txt

Pull request description:

  The dcd6eeb64adb2b532f5003cbb86ba65b3c08a87b commit (bitcoin/bitcoin#23288) introduced an intermittent failure in the `psbt_wallet_tests/psbt_updater_test` unit test. See bitcoin/bitcoin#23368.

  The test failure can be easily made reproducible with the following patch:
  ```diff
  --- a/src/scheduler.cpp

               Function f = taskQueue.begin()->second;

  This PR implements an idea which was mentioned in the [comment](https://github.com/bitcoin/bitcoin/issues/23368#issuecomment-953796339):
  > Yes, as I said before this looks like a race where the wallet is deleted before stopping the scheduler: [#23368 (comment)](https://github.com/bitcoin/bitcoin/issues/23368#issuecomment-952808824)
  >
  > IIRC, the order should be:

  >    * delete scheduler

  The second commit introduces a refactoring with no behavior change.

  Fixes bitcoin/bitcoin#23368.

26a50ab322614bceb5bc62e2c282f83e5987bad8 refactor: Split InterpretOption into Interpret{Key,Value} functions (Russell Yanofsky)

Pull request description:

  This is preparation for #16545 or another PR implementing type validation for ArgsManager settings. It fixes misleading usages of existing flags, prevents flags from being similarly misused in the future, and allows validation logic to be added without breaking backwards compatibility.

  ---

  Currently, ALLOW_{INT|BOOL|STRING} flags don't do any real validation, so current uses of these flags are misleading and will also break backwards compatibility whenever these flags are implemented in a future PR (draft PR is #16545).

  An additional complication is that while these flags don't do any real settings validation, they do affect whether setting negation syntax is allowed.

  Fix this mess by disabling ALLOW_{INT|BOOL|STRING} flags until they are implemented, and adding an unambiguous DISALLOW_NEGATION flag. This is done in three commits, with the first commit cleaning up some code, the second commit adding the DISALLOW_NEGATION flag, and the next commit disabling the ALLOW_{INT|BOOL|STRING} flags.

  None of the changes affect behavior in any way.

Pull request description:

  Previously, Add() would return true if the function created a new
  AddressInfo object, even if that object could not be successfully
  entered into the new table and was deleted. That would happen if the new
  table position was already taken and the existing entry could not be
  removed.

  Instead, return true if the new AddressInfo object is successfully
  entered into the new table. This fixes a bug in the "Added %i addresses"
  log, which would not always accurately log how many addresses had been
  added.

d2c4904ef707e2023ceb8dfbfe61a92c4060e100 test: MiniWallet: more deterministic coin selection for coinbase UTXOs (oldest first) (Sebastian Falbesoner)

Pull request description:

  The coin selection strategy for MiniWallet is quite straight-forward: simply pick a single UTXO with the largest value:

  ab25ef8c7f/test/functional/test_framework/wallet.py (L173-L174)

  If there are several candidates with the same value, however, it is not clear which one is taken.  This can be particularly problematic for coinbase outputs with fixed block subsidy, since spending could lead to a `bad-txns-premature-spend-of-coinbase` reject if an UTXO from a too-recent block is picked.  Introduce block height as second criteria (saved in `self._utxos` in the methods `generate(...)` and `rescan_utxos(...)`), in order to avoid potential issues with coinbases that are not matured yet. If there is a tie between coinbase UTXOs and non-coinbase UTXOs (the latter are added via `scan_tx(...)`), prefer the non-coinbase UTXOs, since those don't need to mature.

  The issue came up while refactoring the test rpc_blockchain.py, see https://github.com/bitcoin/bitcoin/pull/23371#discussion_r737401936 (PR #23371).

2600db6c36c11bf49a0a113ee2e2274406ade61c test: fix misleading fee unit in mempool_limit.py (Sebastian Falbesoner)

Pull request description:

  The PR is a follow-up to #22543. The helper `send_large_txs` in its current interface has a fee_rate parameter, implying that it would create a transaction with exactly that rate. Unfortunately, this fee rate is only passed to MiniWallet's `create_self_transfer` method, which can't know that we append several tx outputs after, increasing the tx's vsize and decreasing it's fee rate accordingly.

  In our case, the fee rate is off by several orders of magnitude, as the tx's vsize changes changes from 96 to 67552 vbytes (>700x), i.e. the value passed to this function is neither really a fee rate nor an absolute fee, but something in-between, which is very confusing. It was suggested to simply in-line this helper as it's currently only used in this single test (https://github.com/bitcoin/bitcoin/pull/22543#discussion_r701685136, https://github.com/bitcoin/bitcoin/pull/22543#issuecomment-918986896), but I could imagine that this helper may also become useful for other tests and may be moved to a library (e.g. wallet.py) in the future.

  Clarify the interface by passing an absolute fee that is deducted in the end (and also verified, via testmempoolaccept) and also describe how we come up with the value passed. On master, the comment says that the fee rate needs to increased "massively"; this word is also removed because the fee rate only needs to be higher for the test to succeed.

96461989a2de737151bc4fb216221bf49cb53ce6 refactor: const shared_ptrs (Karl-Johan Alm)

Pull request description:

  ```C++
  const std::shared_ptr<CWallet> wallet = x;
  ```
  means we can not do `wallet = y`, but we can totally do `wallet->DestructiveOperation()`, contrary to what that line looks like.

  This PR

  * introduces a new convention: always use const shared pointers to `CWallet`s (even when we mutate the pointed-to thing)
  * uses `const shared_ptr<const CWallet>` everywhere where wallets are not modified

  In the future, this should preferably apply to all shared pointers, not limited to just `CWallet`s.

  Both of these serve the same purpose: to dispell the misconception that `const shared_ptr<X>` immutates `X`. It doesn't, and it's dangerous to leave this misconception as is, for obvious reasons.

2095df7b7b [addrman] Add Add_() inner function, fix Add() return semantics
Previously, Add() would return true if the function created a new
AddressInfo object, even if that object could not be successfully
entered into the new table and was deleted. That would happen if the new
table position was already taken and the existing entry could not be
removed.

Instead, return true if the new AddressInfo object is successfully
entered into the new table. This fixes a bug in the "Added %i addresses"
log, which would not always accurately log how many addresses had been
added.

p2p_addrv2_relay.py and p2p_addr_relay.py need to be updated since they
were incorrectly asserting on the buggy log (assuming that addresses are
added to addrman, when there could in fact be new table position
collisions that prevent some of those address records from being added).

d2c4904ef7 test: MiniWallet: more deterministic coin selection for coinbase UTXOs (oldest first)
The coin selection strategy for MiniWallet is quite straight-forward: simply
pick a single UTXO with the largest value:

self._utxos = sorted(self._utxos, key=lambda k: k['value'])
utxo_to_spend = utxo_to_spend or self._utxos.pop()

If there are several candidates with the same value, however, it is not clear
which one is taken.  This can be particularly problematic for coinbase outputs
with fixed block subsidy, since spending could lead to a
'bad-txns-premature-spend-of-coinbase' reject if an UTXO from a too-recent
block is picked.  Introduce block height as second criteria (saved in
self._utxos in the methods generate(...) and rescan_utxos(...)), in order to
avoid potential issues with coinbases that are not matured yet.

4718897ce3a7c728ff7aebbadabcc8ed7a0b8d6e test: add script_util helper for creating bare multisig scripts (Sebastian Falbesoner)

Pull request description:

  This PR is a follow-up to #22363 and #23118 and introduces a helper `keys_to_multisig_script` for creating bare multisig outputs in the form of
  ```
  OP_K PubKey1 PubKey2 ... PubKeyN OP_N OP_CHECKMULTISIG
  ```
  The function takes a list of pubkeys (both hex- and byte-strings are accepted due to the `script_util.check_key` helper being used internally) and optionally a threshold _k_. If no threshold is passed, a n-of-n multisig output is created, with _n_ being the number of passed pubkeys.

  Add separate `interfaces::Init` subclasses for `bitcoin-wallet`,  `bitcoin-gui`, and `bitcoin-qt` binaries instead of sharing `bitcoind` and `bitcoin-node` init subclasses in different binaries. After this, the new init subclasses can be customized in #10102, so node and wallet code is dropped from the `bitcoin-gui` binary and wallet code is dropped from into the `bitcoin-node` binary.

Merge bitcoin/bitcoin#23306: Make AddrMan support multiple ports per IP
92617b7a758c0425330fba4b886296730567927c Make AddrMan support multiple ports per IP (Pieter Wuille)

Pull request description:

  For a long part of Bitcoin's history, this codebase has aggressively avoided making automatic connections to anything but nodes running on port 8333. I'd like to propose changing that, and this is a first PR necessary for that.

  The folklore justification (eventually actually added as a comment to the codebase in #20668) is that this is to prevent the Bitcoin P2P network from being leveraged to perform a DoS attack on other services, if their IP/port would get rumoured. It appears, at least the current network scale - and probably significantly larger - that the impact is very low at best (see calculations by vasild in https://github.com/bitcoin/bitcoin/issues/5150#issuecomment-853888909 e.g.). Another possible justification would be a risk that treating different IP:port combinations separately would help perform Eclipse attacks (by an attacker rumouring their own IP with many ports). This concern is (a) no different than what is possible with IPv6 (where large ranges of IP addresses are very cheaply available), and (b) already hopefully sufficiently addressed by addrman's design (which limits access through based selected based on network groups).

  And this policy has downsides too; in particular, a fixed port is easy to detect, and a very obvious sign a Bitcoin node is running there.

  One obstacle in moving away from a default port that is the fact that addrman is currently restricted to a single entry per IP address. If ports are no longer expected to be generally always the default one, we need to deal with the case where conflicting information is relayed. It turns out there is a very natural solution to this: treat (IP,port) combination exactly as we're treating IPs now; this automatically means that the same IP may appear with multiple ports, simply because those would be distinct entries. Given that indexing into addrman's bucket _already_ uses the port number, the only change required is making all addrman lookup be (IP,port) (aka `CService`) based, rather than IP (aka `CNetAddr`) based.

  This PR doesn't include any change to the actual outbound connection preference logic, as perhaps that's something that we want to phase in more gradually.

b8c069b7a9 refactor: Add explicit DISALLOW_NEGATION ArgsManager flag to clarify flag usage
Currently, ALLOW_{INT|BOOL|STRING} flags don't do any real validation,
so current uses of these flags are misleading and will also break
backwards compatibility whenever these flags are implemented in a future
PR (draft PR is #16545).

An additional complication is that while these flags don't do any real
settings validation, they do affect whether setting negation syntax is
allowed.

Fix this mess by disabling ALLOW_{INT|BOOL|STRING} flags until they are
implemented, and adding an unambiguous DISALLOW_NEGATION flag. This is
done in two commits, with this commit adding the DISALLOW_NEGATION flag,
and the next commit disabling the ALLOW_{INT|BOOL|STRING} flags.

Pull request description:

  In the test `p2p_segwit.py`, there are many instances where we send a segwit block to a node with the expectation that it is rejected. For this purpose, the helper function `test_witness_block` exists which allows also to check for a specific reject `reason` that is asserted in the debug log:
  502d22ceed/test/functional/p2p_segwit.py (L119-L120)

  This PR aims to increase the precision of the tests by adding the expected reject reasons to all `test_witness_block` call instances (found via `grep`ing after `test_witness_block(.*accepted=False`). For some blocks that are rejected due to failed script verification, the exact reason is only shown in the debug log if parallel script verification is disabled. For this reason, the addition of the reasons is split up in two commits:
  * first, all instances are tackled that are not subject to script verification, i.e. it doesn't matter whether parallel script verification is enabled or not (e.g. `bad-blk-weight`, `bad-witness-merkle-match`...)
  * then, we explicitely set `-par=1` to only use one script thread, and add the remaining reasons (`non-mandatory-script-verify-flag` with the more specific reason in parantheses)

a78c2298080f173d0266e708267458a72eb2f600 tests: Place into mapWallet in coinselector_tests (Andrew Chow)

Pull request description:

  #23288 changed coinselector_tests to use `DescriptorScriptPubKeyMan`, but it also ended up significantly slowing down the test, from 4 seconds to over 1 minute. It appears that the source of this slow down is with `CWallet::AddToWallet`, and primarily due to writing data to the mock wallet database. Because the only thing that is actually needed is for the created transaction to be placed into `CWallet::mapWallet`, this PR removes the call to `AddToWallet` and just places the transaction into `mapWallet` directly. This reduces the test time to 5 seconds.

  To speed things up further, `CreateMockWalletDatabase` is changed to make a `SQLiteDatabase` instead of a `BerkeleyDatabase`. This is safe because there are no tests that require a specific mock database type.

refactor: use CWallet const shared pointers when possible
While const shared_ptr<X> gives us an immutable shared pointer to a mutable X (we can't set it to some other X later), shared_ptr<const X> gives us a shared pointer to an immutable X. Importantly, we can recast shared_ptr<X> into shared_ptr<const X>, but not the other way around. We do this for two reasons: because it makes the code safer to guarantee the wallet is not modified, and because it further dispells the misconception that const shared_ptr<X> gives immutability to X.

We want this convention, as it helps alleviate the misconception that a const shared pointer somehow results in a pointer to an immutable object, which is false.

a52f1d1340 walletdb: Use SQLiteDatabase for mock wallet databases
Default to SQLiteDatabase instead of BerkeleyDatabase for
CreateDummyWalletDatabase. Most tests already use descriptor wallets and
the mock db doesn't really matter for tests. The tests where it does
matter will make the db directly.

a78c229808 tests: Place into mapWallet in coinselector_tests
Instead of using AddToWallet so that making a COutput will work,
directly add the transaction into wallet.mapWallet. This bypasses many
checks that AddToWallet will do which are pointless and just slow down
this test.

  Use `Object::tr`, `QT_TRANSLATE_NOOP`, and `QCoreApplication::translate` as appropriate instead of using `_()` which doesn't get picked up.

  Replaces bitcoin/bitcoin#22764

  Edit: I checked that the strings end up in the appropriate context in `bitcoin_en.ts` after `make translate`:
  - "Settings file could not be read" "Settings file could not be written" end up in `bitcoin-core`
  - "(press q to shutdown and continue later)" and "press q to shutdown" end up in `SplashScreen`

Pull request description:

  The RPC gettransaction, listtransactions, and listsinceblock helps returned by `TransactionDescriptionString()` inform the user that the `trusted` boolean field is only present if the transaction is trusted and safe to spend from.

  The field is in fact returned by `WalletTxToJSON()` when the transaction has 0 confirmations (or negative confirmations, if conflicted), and it can be true or false.

  This patch fixes the help, adds test coverage, and touches up the help for the neighboring `generate` field.

d047ed729f1d4732d23324fc76849f3c657cdbe4 external_signer: improve fingerprint matching logic (stop on first match) (Sebastian Falbesoner)

Pull request description:

  The fingerprint matching logic in `ExternalSigner::SignTransaction` currently always iterates all inputs of a PSBT, even after a match has already been found. I guess the reason for that is not that it was not thought of, but rather the fact that breaking out of a nested loop is simply not possible (at least not without adding ugly constructs like gotos or extra state variables).
  This PR fixes this by using `std::any_of` from C++'s standard library, see http://www.cplusplus.com/reference/algorithm/any_of/

Pull request description:

  Currently, various tests use `LegacyScriptPubKeyMan` because it was convenient for the refactor that introduced the `ScriptPubKeyMan` interface. However, with the legacy wallet slated to be removed, these tests should not continue to use `LegacyScriptPubKeyMan` as they are not testing any specific legacy wallet behavior. These tests are changed to use `DescriptorScriptPubKeyMan`s.

  Some of the coin selection tests and benchmarks had a global `testWallet`, but this seemed to cause some issues with ensuring that descriptors were set up in that wallet for each test. Those have been restructured to not have any global variables that may be modified between tests.

  The tests which test specific legacy wallet behavior remain unchanged.

Merge bitcoin/bitcoin#23333: wallet: fix segfault by avoiding invalid default-ctored external_spk_managers entry
6911ab95f19d2b1f60f2d0b2f3961fa6639d4f31 wallet: fix segfault by avoiding invalid default-ctored `external_spk_managers` entry (Sebastian Falbesoner)

Pull request description:

  Fixes #23321 (bug reported by Josef Vondrlik (josef-v)).

  In the method `CWallet::LoadActiveScriptPubKeyMan`, the map `external_spk_managers` (or `internal_spk_managers`, if parameter `internal` is false) is accessed via std::map::operator[], which means that a default-ctored entry is created with a null-pointer as value, if the key doesn't exist.  As soon as this value is dereferenced, a segmentation fault occurs, e.g. in `CWallet::KeypoolCountExternalKeys`.

  The bevaviour can be reproduced by the following steps (starting with empty regtest datadir):

  ```
  $ ./src/bitcoind -regtest -daemon

Merge bitcoin/bitcoin#23140: Make CAddrman::Select_ select buckets, not positions, first
632aad9e6d8369750f4327a886ca5b3d3fed89bd Make CAddrman::Select_ select buckets, not positions, first (Pieter Wuille)

Pull request description:

  The original CAddrMan behaviour (before #5941) was to pick a uniformly random non-empty bucket, and then pick a random element from that bucket. That commit, which introduced deterministic placement of entries in buckets, changed this to picking a uniformly random non-empty bucket position instead.

  I believe that was a mistake. Buckets are our best metric for spreading out requests across independently-controlled nodes. That
  does mean that if a bucket has fewer entries, its entries are supposed to be picked more frequently.

  This PR reverts to the original high-level behavior, but on top of the deterministic placement logic.
