Name has been confusing since it was introduced, and it was pointed in
recent review club as https://bitcoincore.reviews/10102 that it was
particularly unclear how interfaces::WalletClient was different from
interfaces::Wallet.

94d851d28cb909a8f1f8ab795f1d9fc74bebfc7f Fix bnb_search_test to use set equivalence for (Andrew Chow)
Pull request description:
Instead of returning a set of selected coins and their total value as separate items, encapsulate both of these, and other variables, into a new `SelectionResult` struct. This allows us to have all of the things relevant to a coin selection solution be in a single object. `SelectionResult` enables us to implement the waste calculation in a cleaner way.
All of the coin selection functions (`SelectCoinsBnB`, `KnapsackSolver`, `AttemptSelection`, and `SelectCoins`) are changed to use a `SelectionResult` as the output parameter.
Based on #22009

This removes the ability to set an offset in the SpanReader constructor,
as the current code is broken. All call sites use pos=0, so it is actually
unused. If future call sites need it, SpanReader{a, b, c, d} is equivalent
to SpanReader{a, b, c.subspan(d)}.
It also removes the ability to deserialize from SpanReader directly from
the constructor. This too is unused, and can be more idiomatically
simulated using (SpanReader{a, b, c} >> x >> y >> z) instead of
SpanReader{a, b, c, x, y, z}.

456e350926adde5dabdbc85fc0f017fb29bdadb3 wallet: resolve ambiguity of two ScriptPubKey managers providing same script (S3RK)
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.

f13a22a631efe01e1fbae4ae78a4901d14ebda3c wallet: Call load handlers without cs_wallet locked (João Barbosa)
Pull request description:
Don't have `cs_wallet` locked while calling each `context.wallet_load_fns`. A load handler can always lock `cs_wallet` if needed.
The lock was added in 1c7e25db0c to satisfy TSAN. With 44c430ffac most of the code requiring the lock is in `CWallet::AttachChain`. A comment is added to warn about wallets_mutex and cs_wallet lock ordering.

d8ee8f3cd32bbfefec931724f5798cbb088ceb6f refactor: Make CWalletTx sync state type-safe (Russell Yanofsky)
Pull request description:
Current `CWalletTx` state representation makes it possible to set inconsistent states that won't be handled correctly by wallet sync code or serialized & deserialized back into the same form.
For example, it is possible to call `setConflicted` without setting a conflicting block hash, or `setConfirmed` with no transaction index. And it's possible update individual `m_confirm` and `fInMempool` data fields without setting an overall consistent state that can be serialized and handled correctly.
Fix this without changing behavior by using `std::variant`, instead of an enum and collection of fields, to represent sync state, so state tracking code is safer and more legible.
This is a first step to fixing state tracking bugs https://github.com/bitcoin-core/bitcoin-devwiki/wiki/Wallet-Transaction-Conflict-Tracking, by adding an extra margin of safety that can prevent new bugs from being introduced as existing bugs are fixed.

54011e7aa274bdc1b921440cc8b4623aa1e0d89e refactor: use CWallet const shared pointers when possible (Karl-Johan Alm)
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.

Introduce convention to use const shared pointers everywhere, unless the shared pointer is modified at some point, which it very rarely is.
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.
|
|
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.
|
|
For BnB, we only want to check that sets are equivalent with their
values, whereas in knapsack we care about the outpoints.
|
|
|
|
For the generic wallet tests, make DescriptorScriptPubKeyMans. There are
still some wallet tests that test legacy wallet things. Those remain
unchanged.
|
|
The subtract fee from outputs assumes that the leftover input amount
will be dropped to fees. However this only happens if that amount is
less than the cost of change. In the event that it is higher than the
cost of change, the leftover amount will actually become a change
output. To avoid this scenario, force a change type which has a high
cost of change.
|
|
|
|
|
|
To avoid issues with test data leaking across tests cases, the global
vCoins and testWallet are removed from coinselector_tests and all of the
relevant functions reworked to not need them.
|
|
|
|
There is no change in behavior. This just helps prepare for the
transition from boost::filesystem to std::filesystem by avoiding calls
to methods which will be unsafe after the transaction to std::filesystem
to due lack of a boost::filesystem::path::imbue equivalent and inability
to set a predictable locale.

There are two more cases where waste can be 0, when:
- (Fee - LTF) == -Change Cost
- (Fee - LTF) == -Excess
Adding these two conditions explicitly in the unit test will help
pin the behavior, also demonstrate waste calculation scenarios to new
readers.

Followup to commit "MOVEONLY: CWallet transaction code out of
wallet.cpp/.h" that detaches and renames some CWalletTx methods, making
into them into standalone functions or CWallet methods instead.
There are no changes in behavior and no code changes that aren't purely
mechanical. It just gives spend and receive functions more consistent
names and removes the circular dependencies added by the earlier
MOVEONLY commit.
There are also no comment or documentation changes. Removed comments
from transaction.h are just migrated to spend.h, receive.h, and
wallet.h.

Pull request description:
Branch and Bound introduced a metric that we call waste. This metric is used as part of bounding the search tree, but it can be generalized to all coin selection solutions, including those with change. As such, this PR introduces the waste metric at a higher level so that we can run both of our coin selection algorithms (BnB and KnapsackSolver) and choose the one which has the least waste. In the event that both find a solution with the same change, we choose the one that spends more inputs.
Also this PR sets the long term feerate to 10 sat/vb rather than using the 1008 block estimate. This allows the long term feerate to be the feerate that we switch between consolidating and optimizing for fees. This also removes a bug where the long term feerate would incorrectly be set to the fallback fee. While this doesn't matter prior to this PR, it does have an effect following this. The long term feerate can be configured by the user through a new `-consolidatefeerate` option.
